Flat-Rate Tax in Czechia 2026: Rates and Contributions for OSVČ

Updated: 19.07.2026

The flat-rate tax in Czechia (paušální daň) is a single monthly payment for self-employed OSVČ that replaces three separate obligations at once: income tax, social insurance, and health insurance. Three bands apply in 2026 — 9,162, 16,745 and 27,139 Kč per month — and as of 1 July 2026 the first-band payment was reduced from 9,984 to 9,162 Kč, retroactively from January.

The scheme is available to OSVČ with annual income up to 2 million Kč who are not DPH payers. Below you'll find the current 2026 amounts, a comparison with the standard tax scheme, minimum zálohy (advance payments) for social and health insurance, and all the relevant deadlines. If you're just planning to open a živnost in Czechia, it's worth deciding on your tax regime right away — you can only switch it starting from a new calendar year.

What paušální daň is and why it's convenient

The flat-rate tax combines income tax, contributions to ČSSZ (social insurance), and contributions to a health insurer (VZP or another) into a single payment made to the Finanční správa (tax office) account. Payment is due by the 20th of each month.

2026 flat-rate tax rates: three bands

Your band depends on your annual income and the type of activity you do — more precisely, on which percentage expense paušál (80%, 60%, or 40%) you'd be entitled to use under the standard scheme.

BandMonthly paymentOf which taxSocial insuranceHealth insuranceAnnual income
I9,162 Kč (9,984 Kč was paid January–June)100 Kč5,756 Kč3,306 Kčup to 1 million Kč — any activity; up to 1.5 million if at least 75% of income qualifies for the 80% or 60% paušál; up to 2 million if 75% of income qualifies for the 80% paušál
II16,745 Kč4,963 Kč8,191 Kč3,591 Kčup to 1.5 million Kč; up to 2 million if 75% of income qualifies for the 80% or 60% paušál
III27,139 Kč9,320 Kč12,527 Kč5,292 Kčup to 2 million Kč

Which band applies to you with income between 1 and 2 million Kč depends on the structure of your income — it's worth checking the "at least 75% of income at the 80% or 60% paušál" rule with an accountant or on the Finanční správa website.

First-band reduction from July 2026: 4,932 Kč overpayment

Parliament scrapped a planned increase in the minimum social-insurance base from 35% to 40% of the average wage (48,967 Kč in 2026). As a result, the first-band payment dropped from 9,984 to 9,162 Kč — retroactively from 1 January 2026. Anyone who paid at the old rate from January through June now has an overpayment of 4,932 Kč.

Using it is simple: reduce any of your remaining monthly payments for 2026. For example, for July you'd only need to transfer 4,230 Kč instead of 9,162 Kč. You can also spread the overpayment across several months — say, paying 8,340 Kč from July through December — or, if you haven't used it by year-end, request a refund from Finanční správa afterward. Bands II and III remain unchanged.

Who can switch to the flat-rate regime

The application — oznámení o vstupu do paušálního režimu — must be filed by 10 January (or the next business day if that date falls on a weekend; in 2026 the deadline was 12 January) via the MOJE daně portal, a datová schránka, or in person at the tax office. You can't switch mid-year; the exception is new OSVČ, who can join the regime immediately upon registering their business. If you're still deciding on a work format, compare živnost vs. an employment contract.

The standard scheme: OSVČ taxes and contributions in 2026

Outside the flat-rate regime, an OSVČ makes three separate payments and once a year files a tax return plus two přehledy reports — to ČSSZ and to their health insurer. Expenses can be deducted either as actual costs or via a percentage paušál: 80% for trade-based (řemeslná) živnosti and agriculture, 60% for other types of živnost (free-trade, licensed, or concession-based), and 40% for free professions and copyright income.

Health insurance13.5%50% of profit, but no less than the minimum baseVZP or another insurer

The basic personal tax credit (sleva na poplatníka) is 30,840 Kč per year: with modest profit, income tax often ends up at zero, and part of the zálohy already paid gets refunded — we covered how this works in our article on tax refunds in Czechia.

Minimum zálohy in 2026

The same July amendment restored the minimum social-insurance base to 35% of the average wage instead of the planned 40% — minimum monthly advances went down, and the base itself was recalculated retroactively from 1 January 2026. OSVČ pay the new amount starting with the July contribution.

ContributionMain activitySecondary activity
Social insurance (ČSSZ)5,005 Kč from July 2026 (5,720 Kč was paid January–June)1,574 Kč — unchanged
Health insurance3,306 Kč — unchangedno minimum — calculated from actual profit

The January–June overpayment — up to 4,290 Kč for those who paid the minimum — can be reclaimed in three ways: file an application with your local OSSZ by the end of 2026 (funds are refunded within 60 days), ask for it to be credited against future zálohy, or have it factored into the annual přehled calculation for 2026. Check your new payment amount on the ePortál ČSSZ. First-time OSVČ (those who haven't run a business in the last 20 years) benefit from a reduced minimum social-insurance contribution of 3,575 Kč per month; confirm the current figure with ČSSZ. For secondary self-employment with annual profit below the decisive threshold (117,521 Kč in 2026), social-insurance contributions can be skipped entirely. The minimum health-insurance advance remains unchanged at 3,306 Kč per month.

Flat-rate tax or the standard scheme: which is better

There's no one-size-fits-all answer — it all comes down to your profitability and eligibility for deductions. Here are some guidelines.

An exact calculation based on your own numbers takes a specialist under an hour: the tax accountants in our directory can run both scenarios and handle the switch for you.

FAQ: common questions about the flat-rate tax

Do I need to file a tax return under the flat-rate tax?

No, as long as you met the scheme's conditions throughout the year. If your income exceeded your band's limit but stayed within 2 million Kč, you still don't need a full tax return: you file an oznámení (notification) with the tax office and pay the difference up to the higher band's amount — before the tax-return deadline. A full tax return and both přehledy are only required if you breach the scheme's conditions — income above 2 million Kč, or the appearance of employment income.

Can the flat-rate regime be combined with employment?

Practically no: any income from dependent activity, other than income taxed at source (srážková daň), disqualifies you from the regime. Side work under a dohoda o provedení práce within the srážková daň threshold is allowed.

Are child and mortgage deductions taken into account?

No. Under the flat-rate regime, all slevy and deductions are unavailable, including the child tax bonus. If you have significant deductions, the standard scheme is almost always more favorable — run the numbers for both before switching.

What should I do about the first-band overpayment for January–June 2026?

The 4,932 Kč overpayment is already sitting on your tax account. Reduce your July payment to 4,230 Kč, spread the amount across subsequent months, or request a refund from the tax office after year-end.

Does the flat-rate tax count toward pension service?

Yes. The social-insurance portion of the payment goes to ČSSZ, so service years accrue just as for a regular OSVČ. However, in the first band the contribution base is only 15% above the minimum, so the resulting pension will be modest — if you want, you can boost it with voluntary contributions.

What happens if income exceeds 2 million Kč?

You fall out of the flat-rate regime: for that year you must file a tax return and přehledy, and you should also check whether you're now required to register as a DPH payer. If the situation is unclear, bring in an accountant — late filing and late payment both incur fines and penalties.
