Tax on property sale — rules and deadlines

Property‑sale tax applies to a paid transfer completed before the statutory period ends. It most often appears when you sell a flat or house shortly after acquisition and must file PIT‑39. Three elements are key: correct 5‑year counting, proper cost documentation, and checking whether housing relief applies. Below is a practical guide with examples and a checklist to help you settle safely.

When the tax obligation arises

As a rule, PIT applies if the sale occurs before 5 years counted from the end of the acquisition or construction year. After that period, the sale is tax‑neutral. If the sale is earlier, you must calculate income and report it in PIT‑39.

Keep in mind that if the sale is treated as professional activity (e.g., within a business), different rules may apply. In such cases the settlement requires a separate analysis.

How to count 5 years and the acquisition moment

A common mistake is counting the term from the purchase date. The statutory period runs from the end of the year in which the property was acquired or built. In practice, even a few months can shift the “tax‑free” moment. With inheritance or gifts, the acquisition moment may follow specific rules, so it’s worth verifying your case.

Housing relief — when it applies

If you sell before 5 years, you may use housing relief. In short, it requires spending proceeds on your own housing purposes within the statutory time limit and reporting this in PIT‑39. In practice, that can include buying a new property, building, or repaying a housing loan tied to your own needs. The relief is not automatic — you must meet conditions and document the expenses.

The key point is that the expenses must be actually incurred and properly documented. In case of verification, proof of payment and the link to your own housing purpose matter.

Deductible costs — what lowers the tax base

The tax base can be reduced by, among others:

• acquisition cost (price from the deed),
• documented value‑increasing improvements,
• selling costs (e.g., agency, listings, valuations).

Missing documents mean a higher risk that costs will be questioned. Keep invoices and contracts, and consult in doubtful cases.

PIT‑39 and documents — checklist

You file the declaration in the annual PIT deadline, even if you use housing relief. Practical checklist:

1. Acquisition deed and sale deed.
2. Proof of selling costs (agency, listings).
3. Invoices/receipts for improvements.
4. Evidence of housing‑purpose spending (for relief).
5. Verified acquisition date and end of the 5‑year period.

Example and common mistakes

Example (illustrative): sale price 750,000 PLN, acquisition cost 520,000 PLN, improvements 40,000 PLN, selling costs 15,000 PLN. Income is 175,000 PLN. If housing expenses are 60,000 PLN, the base drops to 115,000 PLN and the 19% tax is calculated from that amount.

Common mistakes:

• counting 5 years from the purchase date,
• missing cost documentation,
• skipping PIT‑39 when relief applies,
• confusing inheritance tax with sale tax.
