Mortgages for self-employed buyers in Czechia

A designer invoices a steady stream of clients, pays her taxes on time and has saved a deposit. She applies for a mortgage and is offered much less than she expected, because the bank has read her tax return. The return shows a profit far below her turnover, thanks to a perfectly legal tax method. This is the most common surprise for self-employed buyers in Czechia, and it is easy to see coming.

This explainer covers how banks read a self-employed person's income, which documents they ask for, and how the tax regime you choose affects the loan. It is general information about how lenders behave, not a promise that any bank will lend.

Why the tax return is the starting point

A salaried employee shows payslips. A self-employed person (OSVČ, a person with a trade licence or freelance activity) shows a tax return. The bank's logic is simple: the money you can spend on a mortgage is the money left after business costs, and the most checkable record of that is the return filed with the Financial Administration. Turnover is not income. Profit is.

Czech tax law lets many self-employed people deduct flat-rate expenses instead of actual costs: 80% for crafts and agriculture (expenses capped at CZK 1.6 million a year), 60% for most other trades (cap CZK 1.2 million), 40% for liberal professions (cap CZK 800,000) and 30% for business rental (cap CZK 600,000). The caps mean the flat rate applies in full only up to CZK 2 million of income (as of 2026; check the Financial Administration). Our explainer on the flat-rate tax regime sets this out. The flat rate is convenient and legal, and it produces a low taxable base on purpose.

A hypothetical illustration: a tradesperson with an annual turnover of CZK 1,000,000 who uses the 60% flat rate has a taxable base of CZK 400,000 before deductions. The bank reads the CZK 400,000 line, not the CZK 1,000,000. The figures are invented, and each bank applies its own method, but the principle is general.

Paušální daň and what the bank sees

Some self-employed people use the lump-sum tax regime (paušální daň), which replaces income tax and the social and health insurance advances with one monthly payment, within a turnover band. The attraction is simplicity: no income tax return is filed. The cost, for a borrower, is that there is no tax return for the bank to read. Banks that accept lump-sum taxpayers typically ask for other proof: the notice confirming the regime, bank statements, invoices or a turnover confirmation, and sometimes a confirmation from the tax office. Some banks are more cautious about this group, or count a fixed share of turnover. The bands and amounts change, so check the Financial Administration and ČSSZ for current figures.

If you plan to apply within a year or two, think about which regime produces the record a bank can use. That is a tax question as much as a mortgage question, so ask your accountant, not only your broker.

How long a history do banks want

Banks differ, and the details move, but in market practice a common expectation is at least one completed tax year of self-employment, more often two, and sometimes a longer record if income is volatile. A person who has just started has the hardest time, unless they moved straight from employment into the same field. The reasoning is the same as for employees on probation: the bank wants evidence that the income is stable and likely to continue.

Where income varies, a bank may average two years or use the lower year. A drop in the latest year counts against you. A sharp jump in the latest year may be treated with caution until it repeats.

Documents you will usually need

• the tax returns for the relevant years, with the proof of filing;
• the tax office's confirmation that you have no arrears, and the same from the social security and health insurance bodies;
• proof of the trade licence or registration;
• business account statements, and personal account statements;
• invoices or contracts that show the income is recurring;
• for an accounting entity, balance sheet and profit and loss account.

The social security administration (ČSSZ) and the health insurer issue confirmations of payment status on request. Order them early, because the bank wants them recent. Our guide to becoming self-employed in Czechia describes the registration and contributions behind these papers.

Company owners are a separate case

If you run an s.r.o. and pay yourself a salary or dividends, the bank looks at the salary, the dividends and sometimes the company's accounts. Profit that stays in the company is not your personal income, and a bank may treat it cautiously or ignore it. The choice between running a business as a sole trader or a company is made on tax and liability grounds; see OSVČ versus s.r.o.. Mortgage readiness is one more factor to weigh, not the deciding one.

The own contribution and the rules that apply to all

Self-employed applicants are covered by the same ČNB recommendations as everyone else: a maximum loan-to-value of 80%, or 90% for applicants under 36, and the income limits DTI and DSTI are switched off (as of 2026; check ČNB). A bank may apply a stricter internal LTV to self-employed applicants, so the deposit you need may be higher than the general limit. Our guide to how much deposit you need shows the arithmetic.

If you are a foreign freelancer, the picture has additional layers: a residence permit linked to a trade licence, foreign clients and income in another currency. See mortgages for foreigners and using foreign income for a Czech mortgage. The Hypoteky.com guide to mortgages for foreigners gives a general orientation, and the borrowing estimator shows a rough range, though a self-employed profile is hard to capture in a simple tool.

Frequently asked questions

Frequently asked questions

Do I need two years of self-employment to get a mortgage?

Many banks ask for one to two completed tax years. Policies vary, and a move from the same field of employment can shorten the requirement.

Does the flat rate reduce what I can borrow?

It can, because it lowers the taxable profit that banks usually count. Ask the bank which figure it uses.

Can I use lump-sum tax and still get a mortgage?

Some banks accept it with alternative proof such as statements and a tax office confirmation. Others are stricter. Compare lenders.

Do I need a larger deposit as a freelancer?

Sometimes. The general ČNB limit applies, but a bank can set a stricter one for self-employed applicants.

A practical next step

Take your last two tax returns to a broker or bank adviser and ask one question: what income figure will you use for my application? The answer tells you whether the loan you want is realistic, and whether to adjust your plan a year ahead.
