How to Avoid Inheritance Tax in Poland as a Foreigner: The SD-Z2 Exemption

Close relatives of the deceased — regardless of nationality or where they live — can claim a 100% inheritance tax exemption in Poland by filing form SD-Z2 with the Tax Office (Urząd Skarbowy) within 6 months of the inheritance confirmation becoming legally binding. This includes foreign heirs in the US, UK, Canada, Australia, and elsewhere. The exemption is absolute: you pay zero inheritance tax on any amount, whether the estate is worth 50,000 PLN or 5 million PLN.

The catch is the deadline. Miss the 6-month filing window by even one day and the exemption is permanently forfeited. You then pay standard Group I rates of 3–7% on the entire taxable amount above the statutory allowance (36,120 PLN for Group I in 2026). On an inherited Warsaw apartment worth 800,000 PLN, that's roughly 28,000–53,000 PLN in tax you could have legally avoided.

Who Qualifies for the SD-Z2 Exemption

The exemption applies to Group 0 relatives under Polish inheritance tax law. Citizenship and country of residence don't matter — only the relationship:

• Spouse
• Children (biological and adopted)
• Stepchildren
• Parents
• Siblings
• Grandchildren
• Grandparents

If you fall into any of these categories, you're eligible regardless of whether you're Polish, American, British, or any other nationality.

Who does NOT qualify: More distant relatives (aunts, uncles, cousins, in-laws) and unrelated beneficiaries. They fall under Group I, II, or III with progressively higher tax rates, and no SD-Z2 exemption is available.

The Three Traps That Catch Foreign Heirs

Trap 1: Miscounting the Deadline

The 6-month clock does not start from the date of death. It starts from the date the inheritance confirmation becomes legally binding (prawomocne).

• Notarial route: The Notarial Certificate of Succession (Poświadczenie Dziedziczenia) becomes binding the moment it's registered in the National Register — typically the same day as the notary appointment. Your 6-month clock starts immediately.
• Court route: The Court Decision (Postanowienie o Stwierdzeniu Nabycia Spadku) becomes binding 7 days after the last party is served, assuming no appeal is filed. If the court hearing is in June and the decision is mailed to the last heir in July, your clock may not start until late July.

Foreign heirs who count from the date of death — or from the date of the hearing — often miscalculate by weeks or months.

Trap 2: Not Knowing You Need to File

Polish law doesn't send you a reminder or a tax bill. The Tax Office doesn't know about your inheritance until you tell them. If you don't file SD-Z2, the exemption simply expires. The first time many foreigners learn about the filing requirement is when they try to sell the property and the notary asks for proof of tax settlement.

At that point, the Tax Office assesses back taxes at Group I rates plus interest — and the exemption cannot be retroactively claimed.

Trap 3: Filing the Wrong Form or at the Wrong Office

SD-Z2 must be filed at the Tax Office where the deceased last had their registered residence (zameldowanie), not where you live and not where the property is located. Foreign heirs unfamiliar with Polish administrative geography sometimes file at the wrong office, which can delay processing past the deadline.

The form itself must be filed in Polish. A sworn translation of your supporting documents (inheritance confirmation, identity documents) is required. Filing in English will not be accepted.

Step-by-Step: Filing SD-Z2 as a Foreign Heir

Step 1: Obtain the Inheritance Confirmation

Before you can file SD-Z2, you need a legally binding inheritance confirmation — either a Notarial Certificate or a Court Decision. This is the document that formally establishes you as an heir under Polish law.

Step 2: Identify the Correct Tax Office

Find the Urząd Skarbowy responsible for the deceased's last registered address. If the deceased lived in Warsaw's Mokotów district, you file at US Warszawa-Mokotów. This is not negotiable — the jurisdictional assignment is fixed by the deceased's zameldowanie.

Step 3: Complete Form SD-Z2

The form requires:

• Your identification details (foreign heirs use passport number)
• The deceased's identification details
• The relationship justifying Group 0 classification
• A description of inherited assets and their value
• The date the inheritance confirmation became legally binding

Step 4: Attach Supporting Documents

Include sworn-translated copies of:

• The inheritance confirmation (notarial certificate or court decision)
• Your passport or identity document
• Any property valuations if real estate is involved

Step 5: Submit Within the 6-Month Window

File in person (through your representative with Power of Attorney), by registered mail (przesyłka polecona) with return receipt, or electronically via ePUAP (requires a Polish Trusted Profile, which some foreign heirs won't have).

For remote heirs: your Polish representative with a properly apostilled PoA can file on your behalf. Registered mail counts by the postmark date, not the delivery date — if you're cutting it close, mail is safer than hoping for an in-person appointment slot.

What Happens If You Miss the Deadline

If the 6-month window passes without a valid SD-Z2 filing, you are assessed at Group I tax rates:

For a Warsaw apartment worth 800,000 PLN, the tax on the amount above the allowance (763,880 PLN) would be approximately 53,000 PLN. For a bank account with 200,000 PLN, approximately 11,400 PLN.

There is no appeal, no hardship exception, and no way to retroactively claim the exemption. The deadline is absolute under the Polish Tax Ordinance.

The EU Regulation 650/2012 Complication

Under EU Succession Regulation 650/2012, the law governing the succession is the law of the deceased's habitual residence at death — unless they chose the law of their nationality in a will. But Polish inheritance tax is a separate matter from succession law. Even if the succession itself is governed by US, UK, or Australian law (because the deceased habitually resided there), any Polish assets — bank accounts, real estate, vehicles — are still subject to Polish inheritance tax.

This means a British expat who dies in London with a Polish bank account triggers a Polish tax obligation on that account. The SD-Z2 exemption still applies if the heir is a qualifying relative, but the filing must still happen at the Tax Office corresponding to the deceased's last Polish registered address (or, if never registered, at the Tax Office for the capital — US Warszawa).

Who This Is For

• Foreign heirs (US, UK, Canadian, Australian, or any nationality) who qualify as Group 0 relatives and want to claim the 100% inheritance tax exemption
• Families in the early stages of estate settlement who need to understand and track the SD-Z2 deadline
• Remote heirs coordinating with a Polish representative to handle the filing
• Anyone who has already obtained an inheritance confirmation and needs to act on the tax filing before the window closes

Who This Is NOT For

• Distant relatives or unrelated beneficiaries who don't qualify for Group 0 status — they pay standard rates regardless of when they file
• Heirs who already missed the deadline — the exemption cannot be recovered, though a tax advisor can help minimize the assessment
• Estates with no Polish assets — if all assets are outside Poland, Polish inheritance tax doesn't apply

Frequently Asked Questions

Does my nationality affect the SD-Z2 exemption?

No. The exemption is based entirely on your relationship to the deceased, not your citizenship. A US citizen who is the child of the deceased qualifies exactly the same as a Polish citizen who is the child of the deceased. The only difference is that foreign heirs typically need sworn translations and apostilled documents that Polish heirs don't.

Can I file SD-Z2 electronically from abroad?

You can file via ePUAP (the Polish government's electronic platform), but this requires a Polish Trusted Profile (Profil Zaufany), which foreign nationals can only obtain in person at a Polish consulate or government office. For most foreign heirs, filing through a representative with Power of Attorney — either in person or by registered mail — is more practical.

What if I didn't know about the inheritance until after 6 months?

The 6-month clock starts from when you learned of the inheritance, not from the date of death. If you can document that you only learned of your inheritance status after the 6-month mark from the death, the clock starts from your actual knowledge date. However, "learning of the inheritance" means learning of your legal entitlement — typically when the inheritance confirmation is served on you, not when you first heard someone died.

Does Poland have a tax treaty that eliminates the inheritance tax for US or UK citizens?

Poland has no inheritance tax treaty with the United States. There is a limited UK-Poland double taxation convention, but it primarily covers income tax, not inheritance tax. Polish inheritance tax on Polish assets applies regardless of the heir's tax residency. However, some home countries allow a credit for foreign inheritance taxes paid — consult your home-country tax advisor.

Is the SD-Z2 deadline really that strict?

Yes. There is no grace period, no extension process, and no discretionary relief. Polish courts have consistently upheld the absolute nature of the deadline. The only flexibility is in calculating when the clock starts — which is why understanding whether your inheritance confirmation became legally binding through the notarial (immediate) or court (7-day appeal window) route is critical.
