The Czech Republic is being called Europe's new tax paradise for freelancers. Headlines claim a 4% effective income tax. Some say even lower. And with the flat tax regime (paušální daň), you can pay as little as EUR 48/year in actual income tax.
Bulgaria, meanwhile, offers a 10% flat tax — 7.5% effective for freelancers after the automatic 25% expense deduction. Both are EU member states. Both are in Central/Eastern Europe. Both are affordable.
So which one is actually cheaper? The answer depends on how much you earn, what you spend, and how you define "cheaper." This article runs the real numbers — income tax, social contributions, health insurance, cost of living — at four income levels. No cherry-picked statistics. No marketing spin.
How Each Tax System Works
Bulgaria: The 10% Flat Tax
Bulgaria's system is simple. Freelancers (svobodna profesiya) receive an automatic 25% expense deduction on gross income — no receipts required. The remaining 75% is taxed at 10% flat. That's an effective income tax of 7.5% on gross income, regardless of how much you earn. No brackets, no phase-outs, no cliffs.
Social contributions (pension + health) are capped at a maximum monthly insurance base of EUR 2,111.64/month. Once your income exceeds this ceiling, your social payments are fixed — they don't increase further. The total contribution rate is approximately 27.8%.
Since January 1, 2026, all amounts are in euros. For a detailed breakdown, read our Ultimate Guide to Bulgaria Tax Residency.
Czech Republic: The 60/40 Rule
Czech freelancers (OSVČ — osoba samostatně výdělečně činná) have three options:
Option 1: Standard regime with lump-sum expenses (most common)
- 60% lump-sum expense deduction — only 40% of gross income is taxable (capped at CZK 1,200,000 in deductions).
- Income tax: 15% on taxable income up to CZK 1,762,812 (~EUR 70,500); 23% above.
- Basic taxpayer discount: CZK 30,840/year (~EUR 1,230) — deducted directly from tax owed.
- Result: effective income tax of approximately 4-6% on gross income at typical freelancer earnings.
Option 2: Flat tax regime (paušální daň)
- One fixed monthly payment covering income tax + social + health insurance.
- Band I (income up to CZK 1,500,000 / ~EUR 60,000): CZK 9,984/month (~EUR 400) — of which only CZK 100 (~EUR 4) is income tax.
- Band II (up to CZK 2,000,000 / ~EUR 80,000): CZK 16,745/month (~EUR 670).
- Band III (up to CZK 3,000,000 / ~EUR 120,000): CZK 27,139/month (~EUR 1,086).
- Zero paperwork — no annual tax return required.
Option 3: Actual expenses — track real business expenses instead of the 60% lump sum. Rarely beneficial unless you have very high actual costs.
Key difference: The Czech Republic's low headline tax rate comes from the 60% expense deduction. Bulgaria's comes from the flat 10% rate. But income tax is only part of the picture — social contributions are where the comparison gets interesting.
Real Numbers: Tax + Social at Every Income Level
Here's what you actually pay in each country — income tax plus social and health contributions. All amounts in EUR for easy comparison (Czech CZK converted at 1 EUR = 25 CZK).
At EUR 40,000/year
| Bulgaria | Czech Republic (flat tax) | Czech Republic (standard) | |
|---|---|---|---|
| Gross income | EUR 40,000 | EUR 40,000 | EUR 40,000 |
| Income tax | EUR 3,000 | EUR 48 | EUR 1,170 |
| Social contributions | EUR 5,560 | EUR 3,154 | EUR 2,330 |
| Health insurance | (included above) | EUR 1,587 | EUR 1,587 |
| Total tax + social | EUR 8,560 | EUR 4,789 | EUR 5,087 |
| Effective rate | 21.4% | 12.0% | 12.7% |
| Net income | EUR 31,440 | EUR 35,211 | EUR 34,913 |
Winner at EUR 40K: Czech Republic — by approximately EUR 3,500-4,400/year. The flat tax regime is unbeatable at this level.
At EUR 60,000/year
| Bulgaria | Czech Republic (flat tax) | Czech Republic (standard) | |
|---|---|---|---|
| Gross income | EUR 60,000 | EUR 60,000 | EUR 60,000 |
| Income tax | EUR 4,500 | EUR 48 | EUR 2,370 |
| Social contributions | EUR 7,044 | EUR 3,154 | EUR 3,504 |
| Health insurance | (included above) | EUR 1,587 | EUR 1,620 |
| Total tax + social | EUR 11,544 | EUR 4,789 | EUR 7,494 |
| Effective rate | 19.2% | 8.0% | 12.5% |
| Net income | EUR 48,456 | EUR 55,211 | EUR 52,506 |
Winner at EUR 60K: Czech Republic — the flat tax regime saves you EUR 6,755 versus Bulgaria. Even the standard Czech route saves EUR 4,050.
At EUR 100,000/year
| Bulgaria | Czech Republic (standard) | |
|---|---|---|
| Gross income | EUR 100,000 | EUR 100,000 |
| Income tax | EUR 7,500 | EUR 5,670 |
| Social contributions | EUR 7,044 | EUR 5,840 |
| Health insurance | (included above) | EUR 2,700 |
| Total tax + social | EUR 14,544 | EUR 14,210 |
| Effective rate | 14.5% | 14.2% |
| Net income | EUR 85,456 | EUR 85,790 |
At EUR 100K: essentially a tie. The Czech flat tax is unavailable above ~EUR 60K (Band I) or ~EUR 120K (Band III). On the standard route, Bulgaria's capped social contributions nearly equal Czech contributions. The difference is just EUR 334/year.
At EUR 150,000/year
| Bulgaria | Czech Republic (standard) | |
|---|---|---|
| Gross income | EUR 150,000 | EUR 150,000 |
| Income tax | EUR 11,250 | EUR 11,650 |
| Social contributions | EUR 7,044 | EUR 8,760 |
| Health insurance | (included above) | EUR 4,050 |
| Total tax + social | EUR 18,294 | EUR 24,460 |
| Effective rate | 12.2% | 16.3% |
| Net income | EUR 131,706 | EUR 125,540 |
Winner at EUR 150K: Bulgaria — by EUR 6,166/year. Bulgaria's flat 10% rate and capped social contributions create a growing advantage as income rises. The Czech Republic's 23% bracket (which kicks in above ~EUR 70,500) and uncapped social contributions on higher assessment bases work against high earners.
The crossover point: Bulgaria becomes the cheaper option somewhere between EUR 80,000 and EUR 100,000 annual income. Below that, the Czech Republic wins on pure tax burden. Above that, Bulgaria pulls ahead — and the gap widens with every additional euro earned.
Beyond Tax: The Factors That Change the Calculation
Cost of Living: Sofia vs Prague
This is where Bulgaria often wins even at lower income levels. Sofia is 25-40% cheaper than Prague across all categories:
| Expense | Sofia | Prague | Difference |
|---|---|---|---|
| 1-bed apartment (city center) | ~EUR 500/month | ~EUR 750/month | +50% |
| Meal at mid-range restaurant | ~EUR 12 | ~EUR 16 | +33% |
| Monthly transport pass | ~EUR 25 | ~EUR 30 | +20% |
| Gym membership | ~EUR 25 | ~EUR 40 | +60% |
| Groceries (monthly) | ~EUR 200 | ~EUR 270 | +35% |
| Total monthly budget | ~EUR 1,200-1,600 | ~EUR 1,600-2,200 | +30-40% |
At the lower end, the cost-of-living difference is approximately EUR 5,000-7,000/year. This can offset or even exceed the Czech Republic's tax advantage at incomes below EUR 60,000.
Currency: Euro vs Czech Koruna
This factor is underestimated by most comparisons:
- Bulgaria adopted the Euro on January 1, 2026. If you invoice in EUR (which most international freelancers do), there is zero conversion risk. Income, expenses, taxes — everything is in the same currency.
- Czech Republic uses the Czech Koruna (CZK), with no confirmed Euro adoption date. Every EUR invoice involves a CZK conversion. Tax filings are in CZK. A 5% CZK/EUR swing in the wrong direction can wipe out the Czech tax advantage entirely.
Real example: In 2022, the CZK strengthened roughly 7% against the EUR over the year. A Czech freelancer earning EUR 60,000 lost approximately EUR 4,000 in purchasing power versus what they had budgeted — more than the entire tax difference between the two countries at that income level.
Setup Complexity
| Factor | Bulgaria | Czech Republic |
|---|---|---|
| Registration type | Svobodna profesiya (freelancer) | Živnostenský list (trade license) |
| Registration time | 1 day | 1-5 days |
| EU citizens | No residency permit needed | No residency permit needed |
| Non-EU citizens | Digital Nomad Visa (since Dec 2025) | Zivno Visa (stricter) |
| Language barrier | Bulgarian (Cyrillic script) | Czech |
| Tax filing | Annual (deadline April 30) | Annual (deadline April 1) or flat tax (no filing) |
| VAT threshold | EUR 51,130 | CZK 2,000,000 (~EUR 80,000) |
| Accounting language | EUR (since 2026) | CZK |
Other Factors
- Double taxation treaties: Bulgaria has 70+ treaties; Czech Republic has 90+. Both cover all major countries.
- EU access: Both are EU and Schengen members. Czech Republic joined Schengen in 2007; Bulgaria joined in 2024 (air/sea) with full land borders pending.
- Healthcare quality: Prague has an edge in hospital infrastructure. Sofia is catching up with modern private clinics. Both have public healthcare via contributions.
- International community: Prague has a larger, more established expat community. Sofia's is growing rapidly, particularly in tech and digital nomad circles.
- Internet and infrastructure: Both cities offer fast internet (typically 100+ Mbps fiber) and good coworking spaces.
Who Should Choose Which
Choose the Czech Republic if:
