In short
A housing loan from the company social benefits fund (ZFŚS) is cheap, but it is still a loan. Under the KNF Recommendation S (10.7) a bank should make sure the down payment does not come from a credit or a loan, so it will usually not accept it as a down payment. It is not in BIK, but the deduction is visible on your salary certificate and payslip. A loan of 30,000 zł for 5 years at 2% means an instalment of about 526 zł and about 65,000 zł less mortgage. It is safer to use it for purchase costs, renovation or furnishing and always to declare it to the bank.
Who can get a ZFŚS housing loan
The Polish act on the company social benefits fund (ustawa o zakładowym funduszu świadczeń socjalnych) includes “repayable or non-repayable help for housing purposes on terms set out in an agreement” (art. 2 point 1). Employers with at least 50 full-time employees on 1 January must have the fund, and public budget units regardless of size; with 20 to 49 full-time employees the fund is created at the request of a trade union (art. 3). Employees and their families, pensioners and other persons named in the fund’s rules can use it. The act sets no amounts, interest or terms: they are in your employer’s fund rules (regulamin), and help depends on your life, family and financial situation (art. 8). Ask HR for the current rules.
Down payment: usually not
Recommendation 10.7 of the KNF Recommendation S says a bank should make sure the funds for the down payment do not come from a credit, a loan or a grant. A ZFŚS loan is cheaper than a cash loan, but you have to repay it. Non-repayable help from the fund, if the rules provide for it, is different: keep the decision and the transfer confirmation from your employer.
The bank will see it, even without BIK
Employers do not report to BIK, but bank salary certificate forms ask whether your salary is encumbered, on what grounds and by how much a month, and HR usually enters the deducted instalment there. The payout and the lower net salary are visible on your statement. Leaving the loan out of the application or giving a false source of the down payment is a criminal offence in Poland (art. 297 of the Criminal Code).
How much capacity it costs
| You are short of 30,000 zł | Instalment | Less mortgage |
|---|---|---|
| ZFŚS loan, 5 years, 2% | 526 zł | 65,351 zł |
| Cash loan, 5 years, 10% | 637 zł | 79,219 zł |
| ZFŚS loan after the mortgage payout | 526 zł | 0 zł |
The bank tests capacity at 9% over 30 years. The ZFŚS interest rate is an example, set by the fund rules.
Where it really helps
- purchase costs (PCC tax, notary, agency fee) when the down payment comes from your savings and you declare the loan,
- renovation and furnishing after the mortgage is paid out, when it no longer affects the bank’s decision (check whether your loan agreement requires you to report new debts),
- a cash reserve for the first months of repayment.
If the employer writes off part of the loan, the amount is taxable employment income (art. 12(1) of the PIT act). The rules may also make the rest of the loan due at once when you leave the job, and your guarantors are liable if you stop paying.

Frequently asked questions
Can a ZFŚS loan be my down payment in Poland?
Usually not. KNF Recommendation S (10.7) says a bank should make sure the down payment does not come from a credit or a loan, and a ZFŚS loan has to be repaid. Non-repayable help from the fund is different, if the rules provide for it.
Will the bank see a ZFŚS loan if it is not in BIK?
Yes. The salary certificate has a field on salary deductions, where HR usually enters the instalment, and the payout and lower net salary are visible on your statement. You also have to declare it in the application.
What is the best use of a ZFŚS loan when buying a flat?
Purchase costs, if you declare the loan, or renovation and furnishing after the mortgage payout, when it no longer affects the bank’s decision.
