VAT is the tax most likely to surprise a new Bulgarian company owner — not because the rate is unusual, but because the registration triggers are. Some companies must register before earning a single euro of Bulgarian revenue; others can trade for months below the threshold with no VAT at all. Here is the map.
The Basics
- Standard rate: 20% on most goods and services;
- Reduced rate: 9% for a narrow list (hotel accommodation, books and certain others);
- 0% / exempt: intra-EU supplies of goods to VAT-registered buyers, exports outside the EU, and specific exempt activities (financial services, certain real estate transactions, health, education).
VAT returns are filed monthly, by the 14th of the following month, together with sales and purchase ledgers. Once registered, compliance is a rhythm, not an event — which is why registration timing is a real decision.
Trigger 1: The Turnover Threshold
Registration becomes mandatory when your taxable turnover reaches EUR 51,130 (the converted statutory threshold). Once you hit it, you must file for registration within 7 days. Miss the deadline and the NRA will register you retroactively — with VAT due on the sales you made unregistered, out of your own pocket.
Directors should track turnover monthly. The threshold counts taxable turnover — exempt supplies and most foreign-place-of-supply services do not count toward it, which cuts both ways depending on your business model.
Trigger 2: EU B2B Services — the Rule Nobody Expects
Here is the one that catches international founders: a Bulgarian company that receives or provides services to EU businesses must register under the special regime of Art. 97a of the VAT Act regardless of turnover — even from day one.
Buy Google or Meta advertising, pay for SaaS subscriptions from an EU supplier, invoice a German client for consulting — each of these triggers the obligation. The Art. 97a registration is lighter than full registration (you apply reverse charge and cannot deduct input VAT), but it is mandatory, the deadline is 7 days before the first transaction, and penalties apply for operating without it.
In practice, almost every service business we register ends up needing VAT registration immediately. Budget for it from the start.
Trigger 3: Distance Sales and Digital Products (OSS)
Selling goods or digital services to EU consumers? Once your cross-border B2C sales exceed EUR 10,000 per year EU-wide, you charge the customer's local VAT rate — administered conveniently through a single OSS (One Stop Shop) registration in Bulgaria rather than registering in every member state. E-commerce founders should plan for OSS almost by default.
Voluntary Registration: Often the Smart Move
Any company may register voluntarily before reaching the threshold. It usually pays when:
- your clients are VAT-registered businesses (they reclaim your VAT, so the 20% costs them nothing);
- you have significant startup costs — registration lets you deduct input VAT on equipment, software and services;
- you sell mostly zero-rated exports or intra-EU supplies — you charge 0% but reclaim input VAT, often producing refunds.
Voluntary registration is less attractive for B2C businesses selling to Bulgarian consumers, where the 20% comes straight out of your margin.
What Registration Involves
- Application to the NRA (online with an e-signature or through an authorized accountant);
- The NRA may request evidence of activity — contracts, invoices, premises;
- Registration is typically completed within two weeks;
- From then on: monthly returns and ledgers, VIES declarations for intra-EU supplies, and proper VAT invoicing.
Frequently Asked Questions
What is the VAT registration threshold in Bulgaria?
EUR 51,130 of taxable turnover. Reaching it obliges you to apply for registration within 7 days.
Does my company need VAT registration to work with EU clients?
Yes, in almost all service scenarios. Providing services to, or receiving services from, EU businesses triggers mandatory registration under Art. 97a regardless of turnover — including buying EU advertising or software.
What is the VAT rate in Bulgaria?
The standard rate is 20%, with a 9% reduced rate for hotel accommodation, books and certain other supplies. Intra-EU B2B supplies of goods and exports are zero-rated.
Should I register for VAT voluntarily?
Usually yes if your clients are businesses or your sales are zero-rated exports — you reclaim input VAT at no cost to your customers. Usually no if you sell to Bulgarian consumers below the threshold.
How often are VAT returns filed?
Monthly, by the 14th of the following month, together with electronic sales and purchase ledgers.
