If you are self-employed in the Czech Republic paying the minimal social contribution, your monthly expenses are about to decrease. In May 2026, the Czech Parliament voted to reverse a significant social insurance increase that had been in effect since 2024. Most freelancers will see a reduction in their monthly bills starting in June.
Furthermore, because this change is retroactive, you have likely been overpaying since January 2026. This money belongs to you, and here is how to reclaim it.
What Changed and Why?
In 2024, as part of a government “consolidation package,” the minimum assessment base for social insurance was raised from 35% to 40% of the average wage. The assessment base is essentially the “floor” or minimum amount the state uses to calculate your insurance, even if your actual profits are lower.
On May 26, 2026, the Czech Parliament overruled the Senate to drop this base back to 35%.
The Financial Impact:
- Standard Self-Employed: A monthly saving of up to 715 CZK.
- Flat Tax Regime (1st Band): A monthly saving of 822 CZK.
Note: The Flat Tax regime is a simplified system where you pay one fixed monthly amount that covers income tax, social insurance, and health insurance in a single payment. Learn how it works in Czechia in 2026 and whether it’s the right choice for you.
When Do the New Rates Apply?
The lower rates take effect once the President signs the bill and it is published, which is expected in June 2026.
Important: These updates do not happen automatically in your bank’s standing orders. If you have an accountant, contact them immediately to adjust your payments for June.
How to Claim Your 2026 Refund
Since the lower rate applies to the whole year, you have been overpaying since January. Your path to a refund depends on your tax setup:
- Standard Tax Regime: You will need to submit a formal refund request to your local Social Security Administration at the end of the year after you file your annual report.
- Flat Tax Regime: You have two options. You can either reduce your future monthly payments for the rest of 2026 to “use up” the credit.
What to do once the law takes effect
- Confirm your regime: Check your last payment or ask your accountant if you are on the Flat Tax or Standard regime.
- Adjust your payments: Ensure your June/July social insurance payment reflects the new 35% base.
- Plan your refund: Decide if you want the cash now (for Flat Taxers) or at the end of the year.
