What the deadline covers

Property tax in Poland is a local levy. Consequently, the money goes to the municipality where the property sits, not to the national budget. Moreover, cities such as Warsaw administer their own decisions. Therefore, you must check the decision you received from the local tax office. Individuals usually pay the tax in four instalments. The dates are 15 March, 15 May, 15 September and 15 November. However, if your yearly tax does not exceed 100 PLN, you pay it in one instalment on the first date. In addition, the tax can apply to land, buildings, parts of buildings, and separate flats. Owners are not always the only taxpayers. Possessors and perpetual users may also face the charge. Furthermore, state or municipal property managers may sometimes have duties too.

property tax deadline Poland: rates and who sets them

The municipality council sets the rates within legal limits. For 2026, the maximum rate for residential buildings is 1.25 PLN per square metre. Conversely, businesses may face a much higher cap. The top rate for business premises is 35.53 PLN per square metre. However, councils often apply lower rates. Therefore, your actual bill depends on the local decision and your property size. Also, the tax office issues a decision that states the amount and instalment schedule. Consequently, you do not need to calculate the tax yourself.

Late payment, interest and serious penalties

If you miss the 15 September deadline, the amount becomes a tax arrear the next day. Consequently, the tax office can charge late interest. Moreover, the municipality may begin administrative enforcement if you still do not pay. However, missing one instalment does not automatically trigger a massive criminal fine. The high fines reported in the press relate to separate crimes under the Fiscal Penal Code. For example, deliberate concealment of taxable base may lead to fines up to 64,080 PLN in 2026. Nonetheless, ordinary late payment more commonly results in interest and collection costs, not immediate criminal charges.

Bought a property recently? Actions to take

If you bought a property, you must notify the tax office within 14 days. Use form IN-1 for properties and building objects. In addition, provide the attachments the municipality asks for. Moreover, check whether the tax office sent you a new decision. If not, contact the local tax department. Also, ensure you can pay by bank transfer to the designated account. If you lack a PESEL (national ID number), ask the office for guidance. Note: PESEL is the Polish personal ID. ZUS refers to the social insurance institution. NFZ manages public health insurance. These institutions differ from municipal tax tasks, but expats often meet them when registering residency.

💡 GOOD TO KNOW: Check your tax decision well before 15 September. Pay by bank transfer to the account listed on the decision. If you bought a flat, file form IN-1 within 14 days. If you lack a PESEL or Polish language skills, ask a translator or your notary for help. Contact the local Urzad Gminy/City Hall for exact amounts. Keep proofs of payment.
