Bulgaria’s first eurozone year, and the VAT threshold UK SMEs should be watching
Daniel Malbašić, founder of Bulgarian.LLC comments: Bulgaria joined the euro on 1 January 2026. Eight months in, the country’s figures make an awkward advertisement and a useful case study — and one line item in them has a direct read-across for UK SMEs running an EU entity.
The growth number is good. Bulgarian GDP grew 3.1% year on year in the first quarter of 2026, the fourth-highest rate in the European Union.
The inflation number is not. Annual HICP inflation ran 6.3% in May, 5.2% in June and 4.1% in July — easing, but still the second-highest rate in the euro area behind Latvia at 5.6%, against a bloc average of 2.9%. The drivers cited are an external energy shock, second-round effects in services, higher labour costs and food prices — not, on the Commission’s own analysis, the currency changeover itself, though the changeover is what most business owners there blame.
The fiscal position tightened. The 2026 state budget was not adopted until 24 July, seven months into the year, following the resignation of the previous government in December 2025 and a snap election on 19 April. It carries a 5.7% deficit and a EUR 10.1bn new debt ceiling.
The tax rates did not move. Corporate income tax remains a flat 10%, the lowest headline rate in the EU. Dividend withholding tax remains 5% for individual shareholders, and nil for qualifying EU and EEA corporate parents. A proposal in the November 2025 draft budget to double the dividend rate to 10% was never enacted; it lapsed when the government fell, and the July budget did not revive it.
The number with a UK read-across
The item worth a diary note is the VAT registration threshold.
For 2026 it stands at EUR 51,130, and the basis of calculation changed with the euro changeover: registration is now triggered by taxable turnover in the current or previous calendar year, rather than on a rolling twelve-month look-back. For any business near the line, that is a different compliance question with a different answer, and the switch has caught out companies that were tracking the old rolling measure.
A bill before parliament would raise the threshold to EUR 85,000 with effect from 1 January 2027 — the ceiling permitted under the EU’s SME VAT rules. If enacted, it would put Bulgaria’s registration threshold within a few thousand pounds of the UK’s own GBP 90,000, having spent years an order of magnitude below it.
For a UK SME with a small EU-facing subsidiary — the classic post-Brexit structure set up to hold an EU VAT number, service EU customers, or keep a distribution arrangement inside the single market — that changes the arithmetic of whether the entity registers at all in its early years. It is a proposal, not law, and the sensible planning posture is to model both outcomes rather than to act on the draft.
What this does and does not tell a UK business
Two cautions belong on the end of any set of numbers like these.
First, the inflation figure is not a footnote. A 10% corporate rate on profits is attractive; a cost base rising at 4.1% to 6.3% a year erodes the advantage for any operation that actually employs people locally. Bulgaria has been sold to foreign owners for a decade on the tax rate alone. In 2026 the tax rate is the stable part of the picture and the cost base is the volatile one, which is the reverse of the pitch most owners were given.
Second, an EU entity earns its keep through what it actually does. Where a company is managed and controlled, where its people are, and whether it has genuine substance determine how it is treated — by tax authorities and, increasingly, by banks conducting their own reviews. A registered address and a set of accounts filed from elsewhere is not a structure; it is an exposure with a company number.
The eurozone entry has removed one real friction: cross-border invoicing between Bulgaria and the rest of the euro area no longer carries a conversion layer, and the hedging cost that went with it has gone. For a business genuinely trading across the bloc, that is a permanent operational saving, and it is the change with the least commentary attached to it.
