Tax Residency Certificate CFR-1 in Poland, Who Gets It and How to Apply

A tax residency certificate (certyfikat rezydencji, often called CFR-1 after the application form) confirms that you are a Polish tax resident. A foreign payer, bank or tax authority may ask for it to apply a double taxation treaty instead of its own tax rules. In Poland you get it from the tax office within 7 days, and free of charge when you apply online.

What the certificate is and when you need it

The tax office issues the certificate on the basis of art. 306l of the Tax Ordinance. It confirms your place of residence, or a company’s registered office, in Poland for tax purposes. You need it in three typical situations:

• a foreign payer has to withhold tax from a payment to you, for example on royalties, licence fees, interest or dividends, and can apply the reduced treaty rate or an exemption only with proof of your residence;
• a foreign tax authority asks you to prove where you are taxed;
• you claim tax relief or a tax refund abroad.

In Poland the same mechanism works for non-residents. A Polish payer relies on a foreign certificate to apply a treaty rate, and for income such as civil-law contracts or royalties it reports the payment to a non-resident on an IFT-1R, as described in our article on IFT-1 and IFT-1R.

Who counts as a Polish tax resident

Under art. 3 ust. 1a of the Personal Income Tax Act, you are a Polish tax resident if you meet either of two conditions.

• Your center of personal or economic interests is in Poland. Personal interests mean where your family lives and where your everyday life takes place. Economic interests mean where you earn your main income, run your business, hold investments and manage your assets.
• You stay in Poland longer than 183 days in a tax year. The days are counted within the calendar year and, in tax office practice, do not have to be continuous.

A Polish tax resident declares all income in Poland, from Polish and foreign sources, and applies the relevant double taxation treaty to income taxed abroad.

Sometimes a person meets the residency criteria of two countries at once, for example with family in Poland and more than 183 days of work in another country. The treaty between the two countries then decides. Most treaties follow art. 4 of the OECD Model Tax Convention and check a permanent home, the center of vital interests, the habitual abode and nationality, and if none of these settles it, the two tax authorities agree between themselves. The Polish certificate names one country and confirms residency under the treaty with that country, so you need a separate certificate for each country. If you have not formally ended your residency in your previous country, settle this with a tax advisor before you apply.

How to apply online, through e-Doręczenia or on paper

You apply to the tax office (urząd skarbowy) competent for your place of residence or, for a company, for its tax matters. According to podatki.gov.pl there are three channels.

The simplest route is e-Urząd Skarbowy, where the application is under Documents, Submit a document, WN-CFR. You log in through login.gov.pl with a Trusted Profile, an e-ID card or online banking, or with mObywatel. Sending the application from e-Urząd Skarbowy requires consent to e-Korespondencja in your account.

Do not send the application through ePUAP. Since January 1, 2026, a submission in a form other than the ones the Tax Ordinance allows is left unexamined, and the office does not have to tell you (art. 169 § 1b). The form on podatki.gov.pl is recommended but not mandatory, and you can also file a general letter that names the certificate you need. You choose whether you receive the certificate in e-Urząd Skarbowy, at your e-Doręczenia address or on paper.

What to prepare, how long it takes and what period it covers

Have these details ready to avoid follow-up questions:

• your identification data, your PESEL or NIP, name or company name and address in Poland;
• the country for which the certificate is needed;
• the period it should cover;
• the purpose, for example applying a double taxation treaty with a foreign payer;
• if a proxy files for you, a general power of attorney (PPO-1), which is filed only in e-Urząd Skarbowy and need not be attached, or a special power of attorney (PPS-1) with PLN 17 stamp duty.

The office issues the certificate without undue delay and no later than 7 days after the application (art. 306a § 5 of the Tax Ordinance). A refusal takes the form of an order (postanowienie), which you can challenge with an interlocutory appeal (zażalenie) within 7 days of delivery (art. 306c and art. 236 § 2).

That rule comes from art. 306a § 3 of the Tax Ordinance. No Polish provision sets how long a Polish certificate stays valid abroad. The foreign payer applies the rules of its own country, and many ask for a current certificate every year. Apply well before a payment deadline, so that the 7 days the office has, plus delivery, fit in.

CFR-1 for B2B contractors with foreign clients

If you run a sole proprietorship (JDG) and work as a B2B contractor, check first whether your client’s country withholds tax on your payment at all. Fees for services you perform in Poland are usually not taxed at source in the US or the UK. A US client typically asks for form W-8BEN, which documents that you are not a US person.

The certificate matters most when the payer does withhold tax, for example on licence fees for software or other intellectual property, or in countries that tax service fees at source. Some clients’ compliance teams ask for it anyway before the first payment. In the typical case you live and work in Poland, so the income is taxed here under the form of taxation you chose for the JDG, and that form has no bearing on whether you need a certificate.
