Surprising Tax Obligation: Civil Law Transaction Tax May Cost You Thousands

Many individuals are unaware that certain everyday agreements may come with a tax obligation. The Civil Law Transaction Tax (PCC) applies to transactions such as sales, loans, and donations made between private individuals. Under Polish law, taxpayers have just 14 days from the date of the agreement to file a declaration and pay the tax.

Failure to meet this deadline can be costly. In 2025, fines for non-compliance can reach as high as PLN 93,320. One of the most common situations where PCC applies is the purchase of a used car from a private seller. In such cases, the buyer is responsible for paying 2% of the car’s market value, not necessarily the amount stated in the contract. The tax office can verify and challenge undervalued declarations; if discrepancies exceed 33%, the buyer may be charged the cost of a valuation expert.

The PCC-3 form (or PCC-2 if there are multiple taxpayers) must be submitted to the tax office, either in person or electronically, and the corresponding tax paid within 14 days. However, when a notary is involved, as in notarial deeds, the notary takes on the responsibility of filing and paying the tax.

Penalties for delay may include fiscal and criminal proceedings. Fines start at PLN 466.60 and depend on the delay duration and individual circumstances. However, taxpayers may reduce penalties through “active regret”—voluntarily reporting the oversight and settling the due amount with interest.

Certain situations are exempt from PCC, such as purchases from businesses, gifts from close relatives, transactions under PLN 1,000, or buying a vehicle abroad.

Staying informed and timely with these obligations is essential to avoid unexpected and hefty fines.
