VAT is where most foreign-owned Bulgarian companies first meet the tax authority, and where avoidable penalties are most common. Registration is not always optional, the trigger is not always turnover, and the obligation can arise before you expect it.

When registration is mandatory

The familiar trigger is taxable turnover exceeding a threshold over a look-back period REVIEW: current threshold and look-back window. Once crossed, registration must be applied for within a short statutory deadline, and the obligation runs from that point whether or not you have applied.

Less familiar, and more often missed, are the triggers that have nothing to do with your turnover:

  • Intra-EU acquisitions of goods above a set value.
  • Receiving services from a supplier established in another member state, where the reverse charge applies. This can oblige a company with almost no revenue to register — a Bulgarian start-up paying for foreign advertising or software is a routine example.
  • Distance sales to Bulgarian consumers by a business established elsewhere.

A company can therefore be required to register in its first month of trading.

Voluntary registration

Registering before you are obliged to is often the right commercial decision. It allows you to recover input VAT on set-up costs — equipment, professional fees, office fit-out — which is otherwise a permanent cost. It also avoids the awkwardness of issuing invoices without VAT to business customers who expect it.

The trade-off is immediate compliance: returns, ledgers and deadlines from day one, regardless of activity level.

The process

Registration is an application to the National Revenue Agency supported by company documents and evidence of the ground relied on. Processing typically takes a matter of days once the file is complete REVIEW: current statutory processing period. A registered company receives a Bulgarian VAT number valid for intra-EU trade.

The most common cause of delay is an incomplete evidential file rather than any substantive objection.

After registration

Compliance is monthly. Each period you must file a return with purchase and sales ledgers, and pay any balance by the deadline REVIEW: current filing and payment deadline. Intra-EU supplies additionally require recapitulative statements.

Two points that repeatedly cause difficulty:

  • Invoice formalities. Bulgarian rules on invoice content are applied strictly. A deficient invoice can cost the recipient the right to deduct.
  • Refund positions. Companies in a persistent repayment position — exporters and start-ups in particular — should expect verification. Preparing for that in advance is far easier than responding to it under a deadline.

Rates

A standard rate applies to most supplies, with reduced rates for defined categories such as accommodation and certain goods REVIEW: current standard and reduced rates, and the categories each covers. Some supplies are exempt and some zero-rated — the distinction matters, because exempt supplies restrict input recovery while zero-rated ones do not.

Deregistration

Deregistration can be voluntary, where turnover falls below the threshold, or mandatory on cessation. It is not costless: a final adjustment on assets still held may fall due. Companies winding down often overlook this and treat deregistration as a formality.

How we help

We advise on whether an obligation has already arisen, handle the registration file, and work alongside our partner accounting practice on the monthly cycle so the legal and accounting positions do not drift apart. Where a company is already late, we deal with the disclosure and mitigation rather than leaving it to be discovered.
