Bulgaria — which adopts the euro in 2026 — runs the flattest, lowest tax system in the EU: a 10% flat income tax, 10% corporate tax, and 5% dividend tax. The practical consequence is unusual and rather pleasant: it almost doesn't matter which status you choose — you keep a lot either way.
Here's the 2026 net take-home for the same gross as an employee, a freelancer, or through a company:
| Gross / year | Employee | Freelancer | Company | Best |
|---|---|---|---|---|
| €25,000 | €19,400 | €18,434 | €19,306 | Employee, by €93 |
| €30,000 | €23,577 | €22,120 | €23,581 | Company, by €4 |
| €40,000 | €32,577 | €30,094 | €32,131 | Employee, by €446 |
| €50,000 | €41,577 | €39,344 | €40,681 | Employee, by €896 |
| €75,000 | €64,077 | €62,469 | €62,056 | Employee, by €1,608 |
| €100,000 | €86,577 | €85,594 | €83,431 | Employee, by €983 |
(2026 rates, single filer, profit distributed. Estimates — see caveats.)
Two things jump out. First, the three options are within a whisker of each other — at €30,000 the gap is literally €4. Second, look at the effective rates: they fall as income rises, from ~22% down to 13% at €100,000. That's the opposite of every progressive system, and it's the headline reason people move here.
Why the rates fall with income
Bulgaria's income tax is a flat 10% — it never climbs. What varies is social security, which is charged only up to a maximum insurable base. Once your income passes that ceiling, additional earnings are taxed at just the flat 10% with no further contributions. So the more you earn, the closer your effective rate drifts toward 10% — hence 13% at €100k.
Because the flat rate applies to everyone, the employee, freelancer, and company outcomes barely diverge:
- Employee: 10% tax + capped social contributions → usually the narrow winner.
- Freelancer: similar, but the self-employed social contribution (СОЛ) base leaves them a touch behind.
- Company: 10% corporate + 5% dividend ≈ 14.5% combined — competitive, and it even edges ahead at €30k.
The takeaway
In Bulgaria, choose your status for practical reasons — liability, clients, admin — not for tax. The tax system won't punish you either way, which is a genuinely rare thing in Europe. If you want the lowest effective rate, higher income + the social ceiling does most of the work regardless of wrapper.
Caveats (read these)
- These are estimates from a deterministic calculator, not tax advice.
- Figures are in euro (Bulgaria adopts the euro in 2026); the underlying law was denominated in leva and converted at the fixed rate.
- The maximum social insurance base drives the falling effective rate — confirm the current ceiling for your year.
- Optional self-employed sickness cover and employer mid-band rates are simplified.
