From 1 January 2026, the mandatory VAT registration threshold is €51,130 of taxable turnover within a calendar year. This is the euro conversion of the previous BGN 100,000 threshold, applying the fixed BGN/EUR conversion rate of 1.95583. The threshold is monitored on a daily basis; once crossed, the company must submit a VAT registration application to the NRA within 7 calendar days.

Introduction
Value Added Tax (VAT — known in Bulgarian as ДДС, Данък върху Добавената Стойност) is a consumption tax levied on the supply of goods and services in Bulgaria and across the European Union. For businesses, VAT is not a cost — it is a pass-through: collected from customers on behalf of the state and offset against VAT paid on purchases. The net difference is remitted to, or recovered from, the Bulgarian National Revenue Agency (NRA / НАП) each month.
Understanding when VAT registration is required — and when it is strategically advisable — is one of the most important tax questions for any Bulgarian company. Get it wrong in either direction and the consequences are significant: register too late and the NRA will assess backdated VAT liability plus penalties on all taxable supplies made since the threshold was crossed; fail to register voluntarily when it would benefit the business and you forfeit the right to recover input VAT on purchases.
2026 brought two important changes to Bulgarian VAT law. First, with Bulgaria’s adoption of the euro on 1 January 2026, the mandatory registration threshold converted from BGN 100,000 to its euro equivalent of €51,130. Second, the measurement period for the threshold shifted from a rolling 12-month period to the calendar year (1 January to 31 December), monitored on a daily basis. Both changes require Bulgarian companies to adapt their turnover monitoring procedures.
This guide explains every scenario in which a Bulgarian company may be required or advised to register for VAT: the mandatory domestic threshold, the special rules for EU cross-border transactions, the OSS scheme for e-commerce, the rules for foreign companies operating in Bulgaria, and the strategic case for voluntary registration.
What Is VAT and How Does It Work for Businesses?
VAT is applied at each stage of the supply chain. A VAT-registered business charges VAT on its sales (output VAT) and deducts VAT paid on its purchases (input VAT). Only the net amount — output minus input — is remitted to the NRA. If input VAT exceeds output VAT in a given month, the company has a VAT credit that can be offset against future liabilities or claimed as a refund.
For a non-VAT-registered business, the situation is simpler but less favourable: no VAT is charged on sales, but no VAT can be recovered on purchases either. The VAT paid on office supplies, equipment, software, accounting services, and other business inputs becomes a permanent cost rather than a recoverable credit.
| Concept | Description | Example |
|---|---|---|
| Output VAT | VAT charged by the business on its sales and services | A Bulgarian company invoices a client €10,000 + 20% VAT = €12,000 total; the €2,000 VAT is output VAT |
| Input VAT | VAT paid by the business on its purchases | The same company pays €1,200 for accounting services (inc. €200 VAT); the €200 is input VAT |
| Net VAT payable | Output VAT minus input VAT — remitted to NRA by the 14th of the following month | €2,000 output − €200 input = €1,800 net VAT payable |
| VAT credit | When input VAT exceeds output VAT — refundable or offsetable | If input VAT is €3,000 and output is €1,000, the company has a €2,000 VAT credit |
| VAT refund | NRA refunds excess input VAT after three consecutive months of credit position | If credit persists for 3 months, a refund can be applied for; NRA processes within 30 days |
VAT IS NOT A COST FOR VAT-REGISTERED BUSINESSES: A common misconception is that VAT registration increases a company’s tax burden. For B2B companies (whose clients are also VAT-registered), this is not the case: the client recovers the VAT charged, so the gross invoice amount is irrelevant to the client’s cost. For B2C companies (selling to private consumers), VAT registration does affect final prices unless the business absorbs the VAT within its pricing. Bulgaria For Business advises on VAT strategy as part of every accounting engagement.
Mandatory VAT Registration — The Threshold Rule
The 2026 Threshold: €51,130
A Bulgarian company is legally required to register for VAT when its taxable turnover in Bulgaria reaches €51,130 within a calendar year. This threshold applies to the company’s aggregate taxable turnover — the sum of all taxable supplies of goods and services made in Bulgaria.
The threshold of €51,130 is the direct euro conversion of the previous BGN 100,000 threshold (at the fixed BGN/EUR rate of 1.95583). The amount is set by the Bulgarian VAT Act (ЗДДС, Закон за данък върху добавената стойност) as amended following euro adoption.
| Period | Mandatory Registration Threshold | Currency |
|---|---|---|
| Until 31 December 2025 | BGN 100,000 | Bulgarian lev (BGN) |
| From 1 January 2026 | €51,130 | Euro (EUR) |
What Changed in 2026: Calendar Year vs. Rolling 12 Months
The 2026 reform introduced a more significant operational change than the currency conversion: the measurement period for the threshold shifted from a rolling 12-month lookback to a calendar year basis, monitored daily.
Under the pre-2026 rules, a company monitored its turnover over the preceding 12 consecutive months. If at any point during the year the cumulative 12-month total exceeded BGN 100,000, the registration obligation arose. This meant that a company with a strong autumn season could reach the threshold in October based on revenue from the previous November through October.
Under the 2026 rules, the relevant period is 1 January to 31 December of the current year. Turnover resets to zero on 1 January each year. However, the daily monitoring requirement means that a company must track its cumulative year-to-date turnover every day — not just at month end — because the 7-day registration deadline runs from the day the threshold is crossed, not from the end of the month.
| Rule | Pre-2026 | From 2026 |
|---|---|---|
| Measurement period | Rolling 12 consecutive months | Calendar year: 1 January – 31 December |
| Threshold currency | BGN 100,000 | €51,130 |
| Monitoring frequency | Monthly review sufficient | Daily monitoring required |
| Registration deadline | 7 days from end of month in which threshold exceeded | 7 days from the day the threshold is crossed |
| Turnover reset | Continuous rolling; no annual reset | Resets to €0 on 1 January each year |
DAILY MONITORING IS NOW MANDATORY: Under the 2026 rules, a company whose daily cumulative turnover crosses €51,130 must submit a VAT registration application within 7 days of that specific day — not 7 days from the end of the month. This means that a company generating €5,000 per day could cross the threshold on day 11 of the year and must apply by day 18. Bulgaria For Business tracks turnover thresholds for all accounting clients and issues alerts before the threshold is approached.
The 7-Day Registration Deadline
The 7-day deadline is one of the most unforgiving aspects of Bulgarian VAT law. Once the annual taxable turnover exceeds €51,130, the company has exactly 7 calendar days to submit a complete VAT registration application to the NRA. The NRA then has 14 days to process the application and issue the VAT registration certificate.
The liability consequences of missing this deadline are serious. If the NRA discovers that a company conducted taxable supplies after exceeding the threshold without being VAT-registered, it can assess the company as if it were VAT-registered from the date the threshold was crossed — requiring the company to pay the VAT it should have charged on all post-threshold invoices, out of the revenue it received (which did not include VAT). This effectively reduces the company’s post-threshold gross revenue by 20%.
| Event | Deadline |
|---|---|
| Day the €51,130 threshold is crossed (Day X) | Threshold date — registration obligation arises |
| VAT registration application must be submitted to NRA | By Day X + 7 (calendar days) |
| NRA processes application and issues VAT certificate | Within 14 days of complete application receipt |
| First VAT return due | 14th of the month following the first month of VAT registration |
| Penalty for late application | Fine of BGN 500–BGN 5,000 + backdated VAT liability on all post-threshold supplies |
What Counts Towards the €51,130 Threshold?
Not all revenue a Bulgarian company receives counts towards the mandatory VAT registration threshold. Understanding which supplies are included — and which are excluded — is essential for accurate threshold monitoring.
Included in the Threshold Calculation
- Taxable supplies of goods and services in Bulgaria — sales subject to 20% standard VAT or 9% reduced rate
- Zero-rated supplies — exports of goods to non-EU countries and intra-community supplies of goods to VAT-registered EU buyers are zero-rated but still taxable, and count towards the threshold
- Services provided to Bulgarian-established recipients that are taxable in Bulgaria
- Intra-community acquisitions that create a registration obligation (see EU transactions section below)
Excluded from the Threshold Calculation
- VAT-exempt supplies — certain financial services, healthcare, education, insurance, and rental of residential property are VAT-exempt and do not count
- Sales of capital assets (e.g. selling a company vehicle or piece of equipment used in the business)
- Incidental real estate transactions that are not the company’s core business
- Supplies outside Bulgaria — services supplied to non-Bulgarian recipients where the place of supply is outside Bulgaria
IMPORTANT: Services provided by a Bulgarian company to VAT-registered businesses in other EU member states are technically zero-rated in Bulgaria (the client accounts for VAT under the reverse charge mechanism in their country). These supplies are zero-rated but still taxable — they count towards the Bulgarian registration threshold. An IT company in Sofia providing services only to EU corporate clients can therefore reach the €51,130 threshold even though its invoices show 0% VAT.
Voluntary VAT Registration
A Bulgarian company may register for VAT at any time, regardless of its turnover level, from the moment of company registration. Voluntary registration is the norm for internationally oriented businesses, not the exception. For B2B companies trading within the EU, the benefits of voluntary registration from day one substantially outweigh the compliance overhead.
When Voluntary Registration Is Strongly Recommended
| Business Situation | Voluntary Registration Advisable? | Key Reason |
|---|---|---|
| Consulting or services to EU corporate clients | Yes — strongly recommended | Enables zero-rated intra-EU B2B invoicing; EU clients strongly prefer VAT-registered suppliers |
| IT company (SaaS, development, digital services) | Yes — strongly recommended | EU clients apply reverse charge on zero-rated invoices; VAT registration is standard expectation |
| E-commerce (goods to EU consumers) | Yes | Required for OSS registration; enables pan-EU B2C compliance from a single Bulgarian filing |
| Import of goods into Bulgaria | Yes | Import VAT (20%) is recoverable as input VAT only if the company is VAT-registered |
| Significant startup investment in equipment | Yes | Input VAT on equipment purchases is recoverable; can generate a VAT refund in the first months |
| BPO / shared service centre | Yes | Standard for B2B operations with EU counterparties |
| Real estate transactions | Context-dependent | Specific VAT rules apply to property; legal advice recommended |
| Very small local B2C business (e.g. local retail) | Not always | For B2C businesses with purely local clientele and modest turnover, compliance overhead may outweigh benefits |
Key Benefits of Voluntary Registration
- Recovery of input VAT on all business purchases — accounting fees, office rent, equipment, software, professional services
- Issue zero-rated invoices to VAT-registered EU clients — the reverse charge mechanism applies; no Bulgarian VAT is charged
- Enhanced credibility with EU business partners — a Bulgarian VAT number (BG + UIC) is a visible marker of a legitimate, professionally operated EU company
- Eligibility for the EU One Stop Shop (OSS) scheme for B2C e-commerce
- Ability to reclaim import VAT on goods imported from outside the EU
- Avoidance of retrospective registration complications if turnover grows faster than expected
BULGARIA FOR BUSINESS RECOMMENDATION: We strongly recommend voluntary VAT registration from day one for any Bulgarian company that will invoice EU businesses, import goods, or make significant capital expenditure in the first year. The compliance overhead is manageable — one monthly filing — while the commercial and financial benefits are substantial. Our accounting packages include VAT registration and all monthly VAT filings from €80/month.
VAT Registration for EU Cross-Border Transactions
This is one of the most important sections for internationally oriented Bulgarian companies. EU VAT rules create registration obligations that can arise independently of the domestic €51,130 threshold — triggered by specific types of cross-border transactions regardless of the company’s total annual turnover.
Intra-Community Acquisitions of Goods
When a Bulgarian VAT-registered company purchases goods from a VAT-registered supplier in another EU member state, this is an intra-community acquisition. The Bulgarian company accounts for Bulgarian VAT under the reverse charge mechanism: it self-assesses output VAT on the acquisition value and simultaneously deducts the same amount as input VAT. For a fully taxable company, the net VAT effect is zero — but the transaction must be reported.
A non-VAT-registered Bulgarian company that makes intra-community acquisitions exceeding €20,000 in a calendar year becomes obligatorily registered for VAT purposes for those acquisitions, regardless of its domestic turnover. This is a separate registration threshold specifically for intra-community goods purchases.
Services Received from Foreign Suppliers (Reverse Charge)
When a Bulgarian company receives services from a foreign supplier — whether from another EU member state or from outside the EU — and the place of supply is Bulgaria, the Bulgarian company must account for Bulgarian VAT under the reverse charge mechanism. Common examples include: Google Ads, Facebook advertising, cloud software subscriptions (AWS, Azure, Salesforce), consulting from foreign providers, and any digital service from a non-EU provider.
If a Bulgarian company receives such services and is not VAT-registered, it may be required to register specifically to account for reverse charge VAT on these supplies — again, independently of the domestic turnover threshold.
Intra-Community Supplies of Goods
A Bulgarian company that sells and dispatches goods to a VAT-registered buyer in another EU member state makes an intra-community supply. This supply is zero-rated in Bulgaria (the buyer accounts for VAT in their country), but the Bulgarian company must be VAT-registered to apply the zero rate and must report the supply in a monthly VIES declaration.
| Transaction Type | VAT Treatment in Bulgaria | Registration Consequence |
|---|---|---|
| Services provided to EU VAT-registered business (B2B) | Zero-rated — reverse charge applies in client’s country; 0% VAT on invoice | Must be VAT-registered to issue zero-rated invoice; counts towards domestic threshold |
| Goods sold to EU VAT-registered business | Zero-rated intra-community supply; must verify client VAT number via VIES | Must be VAT-registered; VIES declaration required monthly |
| Goods purchased from EU VAT-registered business | Reverse charge — self-assess Bulgarian VAT; simultaneously deductible as input VAT | If acquisitions exceed €20,000/year: mandatory registration for acquisitions |
| Services received from EU or non-EU supplier (B2B) | Reverse charge — Bulgarian company self-assesses VAT | May trigger registration obligation even if domestic threshold not reached |
| Digital services to EU consumers (B2C) | VAT of consumer’s country applies — OSS scheme simplifies compliance | OSS registration required if EU B2C digital sales exceed €10,000/year |
E-Commerce and the EU One Stop Shop (OSS) Scheme
The EU Distance Selling Threshold: €10,000
The EU introduced a harmonised threshold for B2C distance sales in 2021. A Bulgarian company selling goods or digital services to private consumers in other EU member states is subject to the VAT rules of the consumer’s country once its total annual EU B2C sales exceed €10,000. Below €10,000, Bulgarian VAT applies to all EU B2C sales.
Once the €10,000 threshold is exceeded, the seller has two options: register for VAT in each EU country where consumers are located (impractical for small businesses), or register for the EU One Stop Shop (OSS) scheme in Bulgaria and file a single quarterly OSS VAT return covering all EU member states.
The EU One Stop Shop (OSS) Scheme
The OSS scheme allows a Bulgarian company to register for VAT in a single EU member state (Bulgaria) and report and pay VAT on all B2C sales of goods and digital services across all 27 EU member states through a single quarterly return filed with the Bulgarian NRA. The NRA then distributes the VAT to the relevant member states.
- Who needs OSS: Any Bulgarian company making B2C sales of goods or digital services to consumers in other EU member states exceeding €10,000 per year in aggregate
- How to register: OSS registration is handled by the Bulgarian NRA through the NRA’s e-services portal; a Bulgarian VAT number is required before OSS registration
- Filing: Quarterly OSS VAT returns; different VAT rates apply depending on the consumer’s country; the OSS return must show sales broken down by member state
- Payment: The total OSS VAT due for all EU countries is paid to the Bulgarian NRA, which distributes it to the relevant member states
- Platforms and marketplaces: Amazon, eBay, Shopify, and other marketplace platforms may collect and remit VAT on behalf of sellers under EU deemed supplier rules; the interaction with the seller’s own OSS registration must be managed carefully
| E-Commerce Scenario | VAT Treatment | Registration Required |
|---|---|---|
| Bulgarian company sells to Bulgarian consumers only | 20% Bulgarian VAT on all sales | Only if domestic threshold (€51,130) exceeded; optional otherwise |
| Bulgarian company sells to EU consumers, total EU B2C sales < €10,000/year | 20% Bulgarian VAT on all sales regardless of consumer’s country | Optional — voluntary Bulgarian VAT registration recommended |
| Bulgarian company sells to EU consumers, total EU B2C sales > €10,000/year | VAT of each consumer’s country applies to sales in that country | OSS registration required (via Bulgarian NRA); Bulgarian VAT registration is a prerequisite |
| Bulgarian company sells digital services to EU consumers via platform | Platform (deemed supplier) may collect VAT; check platform’s VAT handling | Consult with Bulgaria For Business on interaction between platform VAT and OSS |
| Bulgarian company sells goods to EU VAT-registered businesses (B2B) | Zero-rated — reverse charge in buyer’s country | Bulgarian VAT registration required to issue zero-rated invoices; VIES declaration required |
Non-Residents and Foreign Companies — Special Rules
For foreign companies — those established outside Bulgaria that conduct taxable activities in Bulgaria — the domestic €51,130 threshold may not apply at all. This is one of the most frequently overlooked aspects of Bulgarian VAT law for internationally managed companies.
A foreign company (a company established outside Bulgaria) that makes taxable supplies in Bulgaria — for example, by selling goods stored in a Bulgarian warehouse, providing services at a Bulgarian location, or conducting any activity that constitutes a taxable supply in Bulgaria — may be required to register for Bulgarian VAT before making its first taxable supply, regardless of the value of that supply.
The specific rules depend on whether the foreign company has a fixed establishment in Bulgaria (a branch, office, or place from which it conducts business), whether it appoints a Bulgarian tax representative, and the nature of its taxable activities. This area of VAT law is complex and company-specific; Bulgaria For Business strongly recommends obtaining specific legal and tax advice before a foreign company commences any taxable activity in Bulgaria.
| Entity Type | Mandatory Registration Threshold | Key Note |
|---|---|---|
| Bulgarian company (EOOD, OOD) | €51,130 annual taxable turnover in calendar year | Daily monitoring required; 7-day registration deadline upon threshold breach |
| Bulgarian company — intra-community acquisitions only | €20,000 annual intra-EU goods purchases | Separate threshold; triggered by buying goods from EU suppliers above this level |
| Foreign company with Bulgarian taxable activity | May be required before first taxable supply | No minimum threshold in many cases; legal advice essential before commencing activity |
| Foreign company — digital B2C services to Bulgarian consumers | First supply may trigger registration or OSS obligation | EU non-Union OSS scheme available for non-EU companies; Bulgarian VAT registration may be required |
TAX REPRESENTATIVE: A non-EU company registering for Bulgarian VAT may be required to appoint a Bulgarian tax representative — a locally established person or entity that assumes joint liability for the company’s Bulgarian VAT obligations. Bulgaria For Business acts as tax representative for qualifying non-EU entities. Contact our team before initiating any Bulgarian VAT registration for a non-Bulgarian company.
Bulgarian VAT Rates — Overview
Bulgaria applies three VAT rates and several special treatments to different categories of supply. All VAT-registered companies must apply the correct rate to each supply they make.
| Rate | Description | Common Applications |
|---|---|---|
| 20% — Standard rate | Applies to all goods and services not covered by a reduced or zero rate; the default rate for most business transactions | Consulting, IT services, professional services, software, most goods, office rental, advertising |
| 9% — Reduced rate | Applies to specific categories defined by the Bulgarian VAT Act and EU VAT Directive | Hotel accommodation and tourist packages; physical and electronic books; baby food; certain food products |
| 0% — Zero rate (taxable) | Zero VAT charged but the supply is taxable; input VAT is recoverable | Exports of goods outside the EU; intra-community supplies to VAT-registered EU buyers; international transport |
| Exempt (no VAT) | Outside the scope of VAT; no VAT charged; no right to deduct input VAT on related costs | Healthcare services; education; financial and insurance services; residential property rental; postal services |
| Reverse charge — 0% on invoice | Bulgarian company self-accounts for VAT on behalf of foreign supplier; no VAT on the invoice itself | Services received from EU companies; digital services from non-EU providers; intra-community goods acquisitions |
Advantages and Obligations of VAT Registration
Key Benefits
| Benefit | Practical Impact |
|---|---|
| Recovery of input VAT on all business purchases | VAT paid on accounting fees, office rent, equipment, software, and professional services is fully recoverable; reduces effective cost of all inputs by 20% |
| Zero-rated invoicing to EU VAT-registered clients | Invoices to EU B2B clients show 0% VAT; clients apply reverse charge in their country; no administrative friction for your EU partners |
| Enhanced credibility with EU business partners | A Bulgarian VAT number (BG + UIC) is verifiable via the European Commission’s VIES system; many EU companies require a VAT number from suppliers as a standard procurement criterion |
| Eligibility for EU One Stop Shop (OSS) | OSS is available only to VAT-registered companies; enables pan-EU B2C compliance through a single quarterly Bulgarian filing |
| VAT recovery on imports | Import VAT (20%) paid at Bulgarian customs on goods from non-EU countries is recoverable as input VAT; without VAT registration, this becomes a permanent cost |
| VAT refund entitlement | If input VAT exceeds output VAT for three consecutive months, a refund can be claimed; particularly relevant during startup phases with high capital expenditure |
Ongoing Compliance Obligations
VAT registration creates a permanent set of monthly compliance obligations. All of the following are handled by Bulgaria For Business as part of every accounting package:
| Obligation | Deadline | Description |
|---|---|---|
| Monthly VAT return (Справка-декларация) | 14th of the following month | Summary of output VAT charged and input VAT deductible for the month; filed electronically with NRA |
| VAT purchase ledger (Дневник покупки) | 14th of the following month | Detailed listing of all purchase invoices on which input VAT was claimed |
| VAT sales ledger (Дневник продажби) | 14th of the following month | Detailed listing of all sales invoices issued during the month |
| VIES declaration | 14th of the following month | Required only in months where intra-community supplies of goods or services to EU VAT-registered buyers occurred; reports the amounts and VAT numbers of EU clients |
| Intrastat declaration | 10th of the following month | Required only if annual intra-EU goods trade exceeds statistical thresholds (dispatches > BGN 780,000 or arrivals > BGN 1,550,000) |
| VAT payment | 14th of the following month | Net VAT due (output minus input) transferred to NRA; late payment attracts interest at ~10% per annum |
Common VAT Mistakes Foreign Entrepreneurs Make
Failing to Monitor Turnover Daily
The 2026 shift to calendar-year-based daily monitoring caught many businesses unprepared. A company that generated €4,500/month in January 2026 and experienced rapid growth in Q2 could cross the €51,130 threshold in late May. Without daily tracking, the 7-day deadline passes unnoticed, and the NRA assesses backdated VAT plus penalties. Bulgaria For Business provides automated threshold monitoring for all accounting clients.
Miscalculating Taxable Turnover
Including VAT-exempt supplies (financial services, healthcare, residential rental) in the threshold calculation overstates taxable turnover and may lead to premature registration. Excluding zero-rated exports from the threshold calculation understates it and may cause late registration. The distinction between exempt, zero-rated, and taxable-at-0% supplies is technical and requires professional accounting guidance.
Ignoring EU Cross-Border Triggers
A Bulgarian IT company providing services to EU B2B clients may reach the domestic threshold without receiving a single Bulgarian client payment, as zero-rated intra-EU services count towards the threshold. More critically, the same company receiving reverse-charge services from Google, AWS, or Salesforce may face a registration obligation independently of its own turnover level. Many companies discover this only when the NRA raises a query.
Missing the 7-Day Deadline
The 7-day deadline from the threshold-crossing day is absolute. There is no grace period, no application for extension, and no opportunity to cure a missed deadline without penalty. The only effective mitigation is proactive monitoring with a buffer — Bulgaria For Business issues alerts when clients approach 90% of the registration threshold.
Incorrect Application of the OSS Scheme
OSS is a reporting scheme, not a VAT registration scheme. A company cannot use OSS to avoid Bulgarian VAT registration — OSS registration requires a Bulgarian VAT number as a prerequisite. Additionally, OSS covers B2C sales only; B2B intra-EU supplies must still be reported through the regular Bulgarian VAT return and VIES declaration. Confusing these two streams leads to both over-reporting and under-reporting in different filing systems.
Practical Examples
Example 1: Sofia IT Company — Services to German and French Clients
| Business | Bulgarian EOOD providing software development services exclusively to EU corporate clients (B2B) |
| Annual revenue | €80,000 — entirely from German and French VAT-registered companies |
| VAT on invoices | 0% — zero-rated intra-community services; clients apply reverse charge in their countries |
| Does it count towards threshold? | Yes — zero-rated supplies are still taxable supplies; they count in full towards the €51,130 threshold |
| Registration obligation | Mandatory — revenue of €80,000 exceeds the €51,130 threshold; registration required within 7 days of threshold crossing |
| VIES obligation | Yes — monthly VIES declaration required for all intra-community services to EU VAT-registered clients |
| Bulgaria For Business recommendation | Register voluntarily from day one; EU clients expect a VAT number; enables input VAT recovery on all business costs |
Example 2: E-Commerce Store Selling to EU Consumers via Shopify
| Business | Bulgarian OOD selling physical goods via Shopify to private consumers across the EU (B2C) |
| Annual B2C revenue | €65,000 total; split across Germany (€25K), France (€18K), Netherlands (€12K), others (€10K) |
| Bulgarian domestic sales | €8,000 |
| Total annual turnover | €73,000 |
| Domestic threshold | Exceeded (€73,000 > €51,130) — mandatory Bulgarian VAT registration required |
| EU distance selling threshold | Exceeded (€65,000 EU B2C > €10,000) — OSS registration required |
| Action required | 1) Register for Bulgarian VAT (mandatory); 2) Register for OSS in Bulgaria; 3) File quarterly OSS returns covering all EU B2C sales at each country’s VAT rate |
Example 3: Consulting Company That Crosses €51,130 in May
| Business | Bulgarian EOOD providing marketing consulting to EU and Bulgarian clients |
| Turnover Jan–Apr 2026 | €42,000 (cumulative year-to-date) |
| Threshold crossed | 15 May 2026 — invoice for €10,500 brings year-to-date total to €52,500, crossing €51,130 |
| Registration deadline | 22 May 2026 (7 calendar days from 15 May) |
| Consequence of missing deadline | NRA can assess backdated VAT (20%) on all post-threshold invoices; effectively reduces gross revenue by 20% retrospectively |
| First VAT return due | 14 June 2026 (for the period from registration date through 31 May) |
| Bulgaria For Business action | Threshold alert issued by our system when turnover reaches €45,000; application prepared and submitted before deadline |
Example 4: Foreign Company Making Its First Bulgarian Taxable Supply
| Business | UK-registered LTD providing professional training services at Bulgarian corporate events |
| Bulgarian revenue | €8,000 — first engagement in Bulgaria; well below €51,130 threshold |
| Is threshold registration triggered? | Possibly not — but the €51,130 threshold applies to Bulgarian-established companies; different rules may apply to foreign companies |
| Registration obligation | Potentially required before the first taxable supply in Bulgaria, regardless of value — depends on the nature of the activity and whether the company has a fixed establishment in Bulgaria |
| Action required | Specific legal and VAT assessment before commencing any Bulgarian activity; Bulgaria For Business provides VAT registration assessment for non-Bulgarian entities |
| Tax representative | A non-EU company (UK post-Brexit) may be required to appoint a Bulgarian tax representative; Bulgaria For Business provides this service |
Penalties for Late or Non-Registration
The Bulgarian NRA actively enforces VAT registration deadlines. The penalties for late or missed registration are substantial and apply cumulatively:
| Violation | Penalty |
|---|---|
| Late VAT registration application (after 7-day deadline) | Fine of BGN 500–BGN 5,000 imposed on the company |
| Continued trading without VAT registration after threshold breach | NRA assesses the company as VAT-registered from the date of threshold breach; company is liable for 20% VAT on all post-threshold invoices, whether or not VAT was charged to clients |
| Personal liability of the director | Directors may be personally fined BGN 500–BGN 2,000 for late registration in addition to the company fine |
| Interest on unpaid VAT | ~10% per annum (BNB base rate + 10 percentage points) on any backdated VAT liability from the date it became due |
| Late VAT return filing | Fine of BGN 500–BGN 1,000 per late return; interest on any unpaid VAT at ~10% per annum |
| Failure to issue valid VAT invoice | Fine of BGN 1,000–BGN 10,000; the client’s right to deduct input VAT may also be challenged |
BACKDATED ASSESSMENT IS THE BIGGEST RISK: If the NRA determines that a company should have registered for VAT on, say, 20 March and it only registered in September, the NRA can assess 20% VAT on every invoice issued between 20 March and the actual registration date. If those invoices did not include VAT (because the company was not yet registered), the VAT must be paid out of the revenue already received — effectively reducing net income by approximately 16.7% (20/120) on the unregistered period’s revenue.
Frequently asked questions
Key questions answered for international clients considering Bulgaria.
Yes — and for most internationally oriented businesses, voluntary registration from day one is strongly recommended. A Bulgarian company may register for VAT at any time regardless of its turnover level. The main benefits are: recovery of input VAT on all business purchases; the ability to issue zero-rated invoices to EU VAT-registered clients; and eligibility for the EU One Stop Shop scheme for B2C e-commerce. Bulgaria For Business includes VAT registration in every standard company registration package.
It depends on the nature and location of the taxable activity. A foreign company (not established in Bulgaria) that makes taxable supplies in Bulgaria may be required to register before its first taxable supply, regardless of amount — the domestic €51,130 threshold may not apply. The specific obligation depends on whether the company has a fixed Bulgarian establishment, the type of supply, and applicable EU VAT rules. Professional advice is essential before any non-Bulgarian entity commences taxable activity in Bulgaria.
Yes — effectively. To issue zero-rated invoices to EU VAT-registered business clients, a Bulgarian company must be VAT-registered. Without registration, it would need to charge 20% Bulgarian VAT on all invoices, which EU clients may be able to recover but prefer not to manage. VAT registration is the standard expectation of any EU B2B counterparty. Additionally, zero-rated intra-EU B2B supplies count towards the mandatory registration threshold, so companies with significant EU client revenue will typically cross the threshold in any case.
The EU One Stop Shop (OSS) is a VAT compliance scheme for businesses making B2C sales of goods or digital services to consumers in multiple EU member states. Instead of registering for VAT in each consumer’s country, an OSS-registered Bulgarian company files a single quarterly OSS VAT return with the Bulgarian NRA, covering sales to consumers in all 27 EU member states at each country’s applicable VAT rate. The NRA then distributes the VAT to the relevant member states. OSS is available to any Bulgarian VAT-registered company with EU B2C sales exceeding €10,000 per year.
Within 7 calendar days of the day the €51,130 threshold is crossed. The 7-day period runs from the specific day the cumulative year-to-date turnover exceeds the threshold — not from the end of the month. Under the 2026 daily monitoring requirement, a company must track its turnover day by day. Bulgaria For Business issues alerts to accounting clients when turnover approaches the registration threshold to ensure the 7-day deadline is never missed.
The NRA can impose fines of BGN 500–BGN 5,000 on the company for late application, plus a personal fine of BGN 500–BGN 2,000 on the director. More significantly, the NRA can assess backdated VAT on all taxable supplies made from the date the threshold was crossed until actual registration. If invoices during this period did not include VAT, the company must pay 20% VAT from its own revenue — retrospectively reducing net income on the unregistered period by approximately 16.7%.
Yes, below the €51,130 threshold — but it is typically not advisable. Most IT companies serving EU corporate clients should register voluntarily from day one. EU clients strongly prefer VAT-registered suppliers (zero-rated invoicing is cleaner). Input VAT on business purchases (software, equipment, accounting) is recoverable only if the company is VAT-registered. And zero-rated EU services count towards the mandatory threshold anyway, so most active IT companies will reach the mandatory threshold within their first year.
Yes — practically. Import VAT (20%) is charged at Bulgarian customs on the customs value of imported goods. This import VAT is recoverable as input VAT, but only by a VAT-registered company. A non-VAT-registered company importing goods pays 20% import VAT at customs with no right of recovery — permanently increasing its cost of goods. For any company importing goods regularly, VAT registration is financially essential.
VAT registration is beneficial at any turnover level when: the company makes significant capital expenditure (VAT on equipment and fit-out is recoverable); the company imports goods (import VAT recovered); the company incurs significant operating costs with VAT (accounting, legal, IT services); or the company invoices EU B2B clients and wants to issue zero-rated invoices. For a startup investing €20,000 in equipment in its first month, VAT registration could generate a €4,000 input VAT refund in the first quarter — regardless of whether any revenue has been invoiced yet.
