PIT Tax Return in Poland

Annual tax return preparation and filing assistance

ONE PLUS prepares Polish annual PIT returns for employees, contractors, entrepreneurs and people with several income sources. We review tax residence, PIT-11 and other income statements, family circumstances, reliefs and foreign income.

We select the correct return, such as PIT-37, PIT-36, PIT-28, PIT-38 or PIT-39, calculate the tax and explain any payment or refund. PIT-11 is information supplied by a payer, not the annual return itself, so its figures must be reconciled with other income.

The client receives a reviewed return, help with electronic filing and UPO confirmation, or a correction of an earlier filing. Before submission, we confirm the relevant tax year and official deadline rather than carrying an old campaign’s dates into the current one.

PIT Tax Return Preparation in Poland

ONE PLUS provides professional PIT tax return preparation in Poland for employees, self-employed people, investors and foreign nationals. We select, prepare and file the annual return that matches the client’s income sources. We can also review and correct tax returns that have already been submitted.

We handle both straightforward PIT-37 returns based on PIT-11 forms and more complex tax cases. These may involve income from self-employment, rental property, the sale of real estate, employment abroad, investments, shares, foreign brokerage accounts or cryptocurrency transactions.

You can arrange PIT return preparation in Wrocław at our office or use our service remotely. We work with clients throughout Poland, regardless of where they live. If you are based in Warsaw, Kraków, Poznań, Gdańsk or any other Polish city–or if you have already moved abroad–you can send us your documents online.

The prices shown apply to standard cases where the client provides a complete set of documents. The final price may be higher if the case involves several sources of income, a large number of cryptocurrency transactions, foreign brokerage accounts, income from more than one country, the sale of property or corrections covering several tax years.

Preparation time is counted from the moment we receive all the necessary documents. It does not include the time required by the Polish tax office to process the return or issue a refund. We always confirm the final price and expected completion time before starting work.

Which PIT Returns Do We Prepare?

PIT-37 is the most common annual tax return for employees and people working under an umowa o pracę, umowa zlecenia or umowa o dzieło, where tax advances were deducted by a Polish employer or payer.

PIT-36 may be required for certain types of foreign income, unregistered business activity or self-employment taxed under the general rules. PIT-36L is used by self-employed people who pay the 19% flat-rate income tax.

PIT-28 applies mainly to private rental income and business activity taxed under the Polish lump-sum system known as ryczałt. PIT-38 covers income from shares, securities, financial instruments and cryptocurrency. PIT-39 is used when reporting income from the sale of property.

We also prepare the relevant attachments, including PIT/O and PIT/ZG, and correct returns for both the current year and previous tax years.

If you have more than one type of income, you may need to file more than one return. For example, employment income may be reported on PIT-37, while income from shares or cryptocurrency is reported separately on PIT-38.

PIT-37 Preparation Based on PIT-11

PIT-11 is the tax document issued by your employer. It shows your annual income, tax advances, deductible employment costs and social security contributions.

Using your PIT-11, we prepare the PIT-37 return, check your personal details, combine information from several employers and calculate whether you are entitled to a refund or need to pay additional tax. We also check which tax reliefs may apply to your situation.

Once you approve the calculation, we file the return and provide you with the official confirmation of submission, known as UPO.

If you worked for more than one employer during the year, you should provide a PIT-11 from each employer. A standard PIT-37 return costs PLN 80 and is usually prepared within one business day after we receive all the required information.

Correcting a PIT Tax Return

ONE PLUS can review and correct a PIT return that has already been filed. A correction may be necessary if your employer issued an amended PIT-11, one source of income was omitted, the wrong form was used or a tax relief was calculated incorrectly.

Corrections are also common when foreign income, investment income, cryptocurrency transactions or deductible expenses were not included in the original return. We can correct both recent returns and returns from previous years.

Our specialist reviews the original filing, recalculates the tax and prepares the amended return. If additional tax is due, we explain how much needs to be paid and which individual tax account should be used.

The price of a standard PIT-37 correction starts at PLN 100.

PIT-38 for Cryptocurrency

Cryptocurrency income and expenses are reported in Poland on a PIT-38 return. The calculation should be based on reliable transaction records and documents confirming the costs of purchasing crypto assets.

We review information from cryptocurrency exchanges and wallets, including purchases, disposals, fees and documented expenses. Where necessary, transactions are converted into Polish złoty in accordance with the applicable tax rules.

We can also carry forward eligible cryptocurrency costs from previous years or correct a PIT-38 return that has already been filed.

The basic price for a cryptocurrency PIT-38 return starts at PLN 150. The final price depends on the number of exchanges, wallets and transactions involved, as well as the format and quality of the transaction history provided.

PIT-38 for Investments and Securities

We prepare PIT-38 returns for income from shares, securities, financial instruments, equity interests and transactions completed through Polish or foreign brokers.

The calculation may include the purchase and sale price of assets, brokerage fees, foreign dividends and tax withheld abroad. Transactions made in foreign currencies must also be converted into Polish złoty using the correct exchange rates.

If a foreign broker has not issued a Polish PIT-8C form, we can prepare the calculation using brokerage statements, transaction reports and other documents supplied by the client.

PIT-39 for the Sale of Property

If you have sold a flat, house, plot of land or a share in a property, you may need to file a PIT-39 return.

Before preparing the return, we check when and how the property was acquired, its purchase and sale price, notarial fees and documented costs relating to renovations or improvements. We also consider whether the property was inherited or received as a gift and whether the housing tax relief may apply.

Tax is calculated on the taxable gain rather than the total sale price. The final result depends on how long you owned the property, which costs can be documented and whether you qualify for an exemption.

We can prepare a new PIT-39 return or correct one that has already been submitted.

PIT-28 for Rental Income

Private rental income in Poland is generally reported on a PIT-28 return. To prepare the calculation, we need information about the rent received, the rental period, the number of properties and any tax payments made during the year.

If the property is jointly owned by spouses, we also check how the rental income should be reported between them. When the rented property is located outside Poland, the calculation may additionally depend on your tax residency and the relevant double taxation agreement.

Preparation of a standard PIT-28 return costs PLN 150.

Foreign Income in a Polish PIT Return

We assist clients who have received income from outside Poland. This may include a salary from a foreign employer, remote work, a foreign pension, rental income, business income, dividends or investment income.

Before preparing the return, we determine the client’s tax residency and check the relevant double taxation agreement. We then establish whether the foreign income must be declared in Poland and whether an additional PIT/ZG form is required.

Foreign income cases are assessed individually because the correct method of taxation depends on the country, the type of income and the client’s personal circumstances.

Tax Reliefs and Refunds

When preparing a PIT return, we check whether the client may qualify for available tax reliefs. These may include child tax relief, joint filing with a spouse, internet relief, IKZE deductions, rehabilitation relief, thermomodernisation relief and deductions for eligible donations.

The final calculation may result in a tax refund, no tax due or an additional payment. We explain the result before submitting the return.

ONE PLUS cannot guarantee that every client will receive a refund. The amount depends on the income earned, tax advances already paid, eligible expenses and the right to claim tax reliefs.

Documents Required for PIT Preparation

For a standard PIT-37 return, we usually need your PIT-11 forms, PESEL or NIP number, current address and information about any tax reliefs you wish to claim. We may also ask for your bank account details if you expect a tax refund.

For more complex returns, additional documents may be required. These may include foreign income statements, proof of tax paid abroad, brokerage reports, cryptocurrency transaction histories, rental documents, property purchase and sale agreements, invoices confirming eligible expenses or a copy of a previously filed return.

The exact list of documents depends on your sources of income and the type of PIT return required.

How to Order PIT Return Preparation

Contact ONE PLUS and briefly describe your sources of income. We will identify which return or returns you need and tell you which documents to provide.

You can send the documents online or bring them to our office in Wrocław. Our specialist will prepare the calculation and explain whether you are entitled to a refund or need to pay additional tax. Once you approve the result, we will file the return and provide the official UPO confirmation.

A standard PIT return is usually prepared within one business day after we receive the complete set of documents.

I contacted ONE PLUS in Wroclaw when I decided to apply for a residence permit. The team supported my case and advised me on what to prepare and when. I got the result about 5 months later. I was satisfied with the cooperation.

I moved to Poland and eventually decided to start preparing documents to obtain Polish citizenship. I contacted ONE PLUS and I was happy with the cooperation. They helped me choose the necessary documents, gave legal consultations and contacted the offices. I also received advice on legalization and help with sorting out documents in Poland. Everything went smoothly, problems were solved step by step, and I understood what to do at each stage. Thank you to the ONE PLUS team for the help and support!

The help I received concerned immigration, legal residence, preparing documents and obtaining a residence card. It is important to find specialists who know the law, explain each stage clearly and help avoid unnecessary difficulties. Professional legal advice can be useful for understanding application deadlines, the requirements for forms and certificates, and your rights and obligations. I would also highlight the help of an immigration lawyer who can explain complicated issues in plain language, answer questions and guide you through the next steps.

Hello. I would especially like to rate the ONE PLUS agency for the high level of professionalism of the people working there. Aleksander, the coordinator, is a responsible person.

I contacted ONE PLUS about a Polish residence permit. I needed to sort out my documents and understand how to go through all the stages of the application correctly. I received legal advice, help with preparing the necessary documents and explanations about the next steps. Everything became much clearer; I didn't have to search through various sources myself. Thank you for the help and support.

For a long time I could not manage the legalization procedure in Poland on my own. After the consultation everything became much clearer. I received clear answers to all my questions and help preparing the documents. I recommend.

Great service for those who value their time. I needed urgent legalization advice, and the lawyers prepared a plan of action straight away.

Thank you for your help with the legalization of my stay in Poland. Everything was organized professionally, without unnecessary formalities. They prepared the documents, explained everything and stayed in contact.

I asked for help preparing a residence card. The specialists explained everything in detail and suggested the next steps.

For the second time in such a short period I managed to sort out a prepaid card through One Plus, all legally and at the highest level. I recommend.

2024

I decided to contact this company on a friend's recommendation. To be honest, I don't regret it! They helped me with the formalities of registering my company, which operates in a foreign country and can be difficult to handle on your own. They handled everything within the agreed deadline and without unnecessary problems. They always respond and help solve even the most difficult problems. Thank you very much for your cooperation.

2025

The best company that will bring a case to a positive outcome, help you obtain compensation from unfair inspectors and provide competent advice to Wroclaw entrepreneurs. I submitted an application in 2019, the inspector changed 3 times, I received compensation of 2400 zloty and a decision on business activity. And all thanks to One Plus and Tatiana, who handled my case from the very beginning. Without any additional fees, the compensation turned out to be higher than the cost of the service. Thank you for the "walk" with the office and for the professionalism of the whole team!

2023

I registered the reel through ONE PLUS. I really liked how fast it was, the whole procedure took only 2 days. Great!

We applied to One Plus for registration as a sole proprietorship. Later we applied for permanent residence. Collecting the documents did not take long. We submitted the application at the beginning of December, and the document was issued at the beginning of June. Everything went quickly and smoothly. Now we are waiting for our plastic card.
