Poland crypto tax guide 2025: Latest KAS updates

Many crypto activities are tax-exempt under the current KAS guidance. These activities include:

💳  Buying crypto with PLN, EUR, or another fiat currency.

🔁  Transferring crypto between your own wallets.

🔒  Holding crypto.

💸  Trading crypto for crypto.

💰  Receiving cryptocurrencies through a variety of means, for example, mining, staking, airdrops, and more.

Generally speaking, the most common crypto-related activities are subject to capital gains tax treatment.

However, there are some activities that are treated as ordinary income.

Taxable events under the current guidance include:

🏡  Selling crypto for fiat currency.

🤝🏽  Using crypto to purchase goods, services, or property rights

🧸  Settling liabilities with crypto

Any of these transactions that result in a profit will be taxed at 19%.

The current guidance from KAS is only concerned with transactions where crypto is converted to fiat currencies, like PLN. As such, many transactions where you’re in receipt of crypto, which would often be considered income in other countries, may be tax free. 

However, in instances where you’re in receipt of crypto with no allowable costs, it is likely that you’d, therefore, have a zero cost basis, meaning the entirety of your proceeds at the point you converted them to PLN or another fiat currency would be considered taxable. KAS is quite clear that only purchase and sales fees relating to crypto are allowable, and things like mining equipment costs, electricity costs, and so on, would not be allowable costs. 

KAS has very specific requirements for the accounting and reporting of crypto in your tax return.

KAS has made it clear that when reporting cryptocurrency transactions, you must report both your total costs and total sales related to crypto. Costs include all cryptocurrency purchases and any allowable expenses, while sales refer to any income generated from selling crypto. This information must be compiled and reported annually. Even if you don’t generate any income from crypto in a particular year, you are still required to report any costs incurred.

You can calculate your taxable income from crypto using the following formula:

Taxable income from crypto = Total revenue from sales in the year – Tax-deductible costs in the year

If your expenses for acquiring cryptocurrency exceed the income from selling it in a given year (or if you don’t earn any income from crypto sales that year), the excess costs can be carried forward to the next tax year. In future years, you can treat this surplus as part of your regular tax-deductible costs, similar to any new acquisition costs.

Only expenses directly connected to the purchase and sale of virtual currencies qualify as tax-deductible costs.

Expenses related to financing crypto purchases (such as loans or credits) cannot be deducted. Similarly, costs associated with mining—such as mining equipment and electricity—are not tax-deductible. Additionally, costs incurred when exchanging one virtual currency for another are excluded from deductible expenses.

KAS have no guidance on the tax implications of lost or stolen crypto. You should consult with an experienced tax advisor for advice on your specific circumstances.

Once you’ve calculated your costs and sales, you need to report this in your annual tax return in PIT-38 by April 30.

Keeping track of your costs and sales in line with KAS guidance is challenging for active investors. That’s why many choose to use a crypto tax calculator like Koinly to simplify the process.
