The Czech tax system offers numerous ways to reduce what you owe — if you know where to look. Tax credits cut your tax bill directly, while deductions lower your taxable income. Here's your complete guide to maximizing both in 2026.
The Basic Taxpayer Credit
Let's start with the good news: every taxpayer in Czechia gets a basic credit of 30,840 CZK per year. You don't need to do anything special to qualify — if you have taxable income, you get this credit automatically.
This alone covers the tax on approximately 205,000 CZK of income. For many part-time workers or those with modest earnings, it means paying little to no income tax.
Spouse Credit
If your spouse had annual income below 68,000 CZK, you can claim an additional 24,840 CZK credit. This applies whether your spouse stayed home with children, was unemployed, or simply had very low earnings.
For spouses with disabilities, the credit doubles to 49,680 CZK.
Requirements:
- You must be married as of January 1st of the tax year
- You must share a household
- Your spouse's income must be below the threshold
Child Tax Benefit
This is one of the most valuable benefits in the Czech system. The amounts increase with each child:
- First child: 15,204 CZK per year
- Second child: 22,320 CZK per year
- Third and additional children: 27,840 CZK per year
Here's what makes this special: if the credit exceeds your tax liability, you receive the difference as a cash payment (daňový bonus). A family with three children could receive over 65,000 CZK annually.
For children with ZTP/P disability status, all amounts double.
Student Credit
Students up to 26 years old (or 28 for doctoral programs) can claim 4,020 CZK annually. You must be continuously preparing for a profession through study.
Disability Credits
Depending on the degree of disability:
- Disability degree I or II: 2,520 CZK
- Disability degree III: 5,040 CZK
- ZTP/P card holder: 16,140 CZK
Deductions That Lower Your Tax Base
Credits reduce your tax directly. Deductions reduce the income your tax is calculated on. Both save you money, but they work differently.
Mortgage Interest
Interest paid on a mortgage for your primary residence can be deducted up to 150,000 CZK per year. The property must be where you actually live, not an investment property.
Pension Savings
Contributions to pension funds (penzijní připojištění or doplňkové penzijní spoření) are deductible up to 24,000 CZK annually. The deduction applies to contributions exceeding 12,000 CZK per year.
Life Insurance
Private life insurance premiums qualify for deduction up to 24,000 CZK. The policy must meet specific requirements: minimum duration, payout after age 60, and other conditions.
Charitable Donations
Gifts to qualified charitable organizations are deductible if they exceed 1,000 CZK or 2% of your tax base. Maximum deduction is 15% of your tax base.
How to Claim These Benefits
In your tax return:
- Section 5 is for deductions (nezdanitelné části základu daně)
- Section 6 is for credits and child tax benefit
- Attach supporting documents: birth certificates, study confirmations, employer certificates for spouses, etc.
Practical Tips for Maximum Savings
- Check that you're claiming every credit you qualify for
- If both spouses work, calculate who benefits more from child credits
- Consider end-of-year contributions to pension funds to maximize deductions
- Keep all documentation for at least three years after filing
