VAT in Bulgaria: when registration actually applies to you

Most foreigners in Bulgaria never touch ДДС. The moment you start freelancing for clients abroad, though, VAT rules can apply to you well before you'd expect — sometimes from your very first invoice.

If you're an employee on a Bulgarian payroll, none of this applies to you — VAT is a business-side tax. It becomes relevant the moment you invoice anyone yourself: as a freelancer, an EOOD owner, or a landlord running a larger rental operation.

The rates

The standard rate is 20%, applied to most goods and services. A reduced 9% rate applies to a narrower set of categories, most notably hotel accommodation. If you're not sure which rate applies to what you sell, that's a question for an accountant, not a guess — misapplying a rate on invoices is a common, avoidable filing error.

Registration types at a glance

There isn't one single "VAT registration" — Bulgaria has a few, and which one applies to you depends on what you sell and to whom.

The rest of this guide walks through each one. Read the article 97a section closely if you're a freelancer with any EU business clients — it's the one that actually surprises people.

Mandatory registration: the €51,130 threshold

You must register for VAT once your taxable turnover passes €51,130 in a calendar year. A 2026 change matters here: the reference period is now the calendar year, where it used to be a rolling 12 months — so the clock resets every 1 January rather than tracking a continuous trailing window. If you're close to the threshold, know which version applies to your situation.

Once you cross it, you have 7 days to apply for registration with НАП. This isn't a "get around to it" deadline — miss it and you can be liable for VAT retroactively plus penalties.

Watch your running total, not just your invoice-to-invoice amounts — it's easy to notice a big single payment but miss that a string of smaller ones has quietly added up over the year. Reviewing turnover monthly, not just at tax time, is the only reliable way to catch the threshold before you cross it rather than after.

Voluntary registration: registering before you have to

You can register for VAT at any point, regardless of turnover. Two things to weigh before you do:

• It's binding for 24 months — you can't de-register on a whim if it turns out not to suit you.
• It lets you reclaim input VAT on business purchases, which matters if you buy equipment, software, or services with VAT on the invoice and sell mostly to VAT-registered businesses (B2B) who don't mind seeing VAT on your invoices either.

If your clients are mostly consumers or non-VAT-registered small businesses, voluntary registration usually isn't worth the paperwork. If you're B2B-heavy with real input costs, it often is.

The one that catches freelancers off guard: article 97a

This is the rule most people building a company or freelance practice in Bulgaria have never heard of until it applies to them. Under article 97a, a separate registration for services applies even if you're nowhere near the €51,130 threshold, when you:

• Buy services from a business established in another EU country, or
• Sell services to a business established in another EU country

The mechanism exists because cross-border B2B services are usually taxed where the customer is (see reverse charge, below) — the 97a registration is what lets НАП and your counterpart's tax authority track that correctly. Check with НАП or an accountant whether your specific client relationships trigger it; the exact scope depends on where your clients are and what you're selling them.

Selling to EU consumers: the OSS scheme

If you sell digital services directly to consumers (not businesses) across the EU — apps, downloads, online courses, subscriptions — you'd otherwise need to register for VAT separately in every EU country where you have customers. The One Stop Shop (OSS) scheme avoids that: you register once, charge the VAT rate of each customer's country, and file a single consolidated return that distributes the VAT to the right countries. Worth setting up before you have EU consumer customers at any scale, not after.

This matters specifically for B2C, not B2B — if your EU customers are businesses rather than consumers, you're in reverse-charge territory instead (below), which is a different mechanism entirely. Selling a mix of both means tracking, for every sale, whether the buyer is a business or a private individual.

Intra-EU B2B: reverse charge

When you invoice a VAT-registered business in another EU country, the standard mechanism is reverse charge: you invoice without Bulgarian VAT, and your customer accounts for the VAT themselves under their own country's rules. This is the normal, expected way most freelancer-to-EU-business invoices work once you're registered — it's not something you opt into separately.

In practice this means your invoice to a German or French agency client shows 0% VAT with a note that the reverse charge applies, and you don't collect or remit VAT on that sale yourself. It's simpler than it sounds, but it only works cleanly once your own registration (typically triggered by article 97a) is in place — get the sequencing right rather than guessing at the invoice format.

Once you're registered: monthly returns

VAT-registered businesses and freelancers file a VAT return every month, due by the 14th of the following month, regardless of whether you had any VAT-able activity that month. Nil months still need a nil return — missing filings (not just missing payments) draw penalties.

VAT registration is separate from БУЛСТАТ or company registration

Registering as a freelancer (БУЛСТАТ) or setting up an EOOD (Trade Register) doesn't automatically make you VAT-registered — they're different systems with different triggers. You can be a freelancer or company owner for years without ever needing VAT registration, or you can need it from your very first invoice if article 97a applies. Don't assume one registration covers the other; check each separately. See our freelancer vs. company guide for the BULSTAT/Trade Register side.

Records to keep once you're registered

VAT registration comes with a paper trail obligation, not just a return to file: a VAT purchase and sales journal, copies of every invoice issued and received, and proof of the reverse-charge status for any EU B2B transactions. Most freelancers and small EOODs handle this through their accounting software or accountant rather than manually — worth setting up from your first VAT-relevant invoice rather than reconstructing it later.

Where people get stuck

The recurring story is a solo freelancer who checks the €51,130 threshold, sees they're nowhere close, and assumes VAT doesn't apply to them yet — then finds out article 97a already required them to register the moment they started invoicing an EU business client. If any of your income comes from EU business clients, treat the 97a question as something to resolve on day one, not something to revisit once you're bigger. See our freelancer vs. company guide and tax basics guide for how VAT sits alongside income tax and social security in your overall setup.

Quick checklist before your first invoice

• Confirm whether any of your clients are EU-established businesses — if so, check article 97a with НАП before invoicing
• Confirm whether any of your customers are EU consumers buying digital services — if so, look into OSS
• Track your Bulgarian taxable turnover against the €51,130 calendar-year threshold
• Decide whether voluntary registration makes sense given your input costs and client mix
• If registered, calendar the 14th of every month for your VAT return — including nil months
