DAC-8 cryptocurrency reporting in 2026: What data will be sent to the tax authorities?
All cryptocurrency platforms available in Europe are required to collect data relating to your transactions. From 1 January 2026, the Polish tax authorities will have access to this data under the DAC-8 Directive.
The tax office will have access to information on all your transactions involving cryptocurrencies, NFTs, token collections, cryptocurrency contracts and derivatives (CFDs), including:
- Quantity and purchase price
- Quantity and sale price
- Quantity of assets held in your portfolio
- Information on exchanges (e.g. one cryptocurrency for another, NFTs for cryptocurrency)
The data provided to the tax office will also include your first name, surname, tax identification numbers and residential address.
When will DAC-8 come into force? From what date will transaction data be reported to the tax office under DAC-8?
The first data is due to be submitted to the Polish tax offices by the end of January 2027. It will cover all your transactions carried out in 2026.
PLEASE NOTE: if you hold assets acquired or mined before 2026, but sell or exchange them during 2026, they will still be subject to reporting. The tax office has the right to ask you to explain how you came into possession of them – the exchange will not provide this information as part of the DAC-8 for 2026.
When planning transactions involving cryptocurrencies or NFTs, you should analyse the impact of potential tax liabilities and reporting obligations that you will face once the cryptocurrency platform passes on the relevant information to the tax office.
How will DAC-8 affect taxation? What tax rates and obligations apply to cryptocurrencies?
If you are a tax resident in Poland (you stay in Poland for more than 183 days a year, or you have your vital or business interests here) – you are liable for tax in Poland, even if the exchange on which you trade cryptocurrencies is based abroad.
PLEASE NOTE: this also applies to people who have not yet obtained a permanent or temporary residence permit or a Polish Card.
Profits from cryptocurrency transactions are subject to taxation in Poland at a rate of 19%, and must be reported in the PIT-38 tax return.
What if I haven’t declared / don’t declare the sale of cryptocurrencies or NFTs?
The Tax Office has the right to summon you to provide an explanation if you have not filed the relevant tax return in Poland, and your exchange’s DAC-8 report indicates that you hold a wallet there and carry out transactions.
The tax office will seek to estimate your income, for example based on similar transactions from the same period, and summon you to file a tax return and pay the tax along with interest. It may also impose a tax penalty for failing to declare income from cryptocurrencies.
As of the date of publication of this article, penalty interest in such a situation amounts to 16.5% per annum. However, if you report your transactions correctly before being summoned, in most cases you can benefit from the minimum interest rate of 5.5% per annum and avoid a tax penalty and proceedings by the tax office.
What can I do now in relation to the DAC-8 Directive in Poland, and how should I sell cryptocurrencies to avoid penalties and tax interest?
- If you plan to sell cryptocurrency or NFTs acquired in previous years in 2026, you should gather documentation substantiating their acquisition value.
- When planning to sell an asset in 2026, you should factor in the amount of tax that will be payable at the end of the year. Proper planning of cryptocurrency transactions can help you minimise or even avoid tax.
- You should collect the data necessary to report all your transactions at the end of the year.

Please get in touch – we can help you plan your transactions from a tax perspective, calculate the tax due on cryptocurrency sales, prepare explanations, or gather the documents required for your tax return.
In Poland, similar regulations currently apply, for example, to online sales (DAC-7).

That is why it is worth planning your tax returns and transactions now.
We provide support in securing your transactions, determining the lowest possible tax and fees, and if you have already received a summons from the tax office, we can represent you before the authorities and draft the necessary letters and explanations. Please feel free to contact us!
