Professional crypto trader in Poland: PIT-38 and the business exception

Poland does not move ordinary proprietary crypto trading into general business income merely because the person is self-employed or trades frequently. The Ministry of Finance states that acquisitions and disposals of virtual currency are reported in PIT-38 even when performed within a business, except for specified AML-regulated virtual-currency service activity.

Critical classification rule: the Polish Ministry of Finance updated its official virtual-currency page on 24 June 2026. It says PIT-38 is filed even when a person buys or disposes of virtual currency within an existing business. The exception is activity covered by the specified virtual-currency service-provider definition in the AML Act. High trade frequency alone does not activate that exception.

Proprietary trader versus crypto service provider

A tax-report dropdown should not ask every Polish user to choose “professional trader” as if it freely changes rates. It should ask whether the taxpayer conducts the specific regulated service activity and otherwise keep own-account virtual-currency transactions in the statutory PIT-38 stream.

What counts as an odpłatne zbycie?

The official guidance defines taxable disposal as exchanging virtual currency for legal tender, goods, services or a property right other than virtual currency, or settling another obligation with it. A crypto-to-crypto exchange is not taxed at that moment under this regime.

That is different from many countries. A BTC-to-USDT swap should preserve documented costs and quantities but does not by itself create Polish virtual-currency revenue. A later sale for PLN or payment for a service does. The Poland crypto guide explains the annual calculation.

PIT-38, deadline and 19% tax

The annual PIT-38 return is filed from 15 February through 30 April of the following year. The official rate on the positive difference between qualifying virtual-currency revenue and deductible costs is 19%. The report must show current-year costs and previously unabsorbed costs in their proper fields.

Polish exchanges are not generally required to furnish PIT-8C or PIT-11 for these trades. The absence of a statement does not eliminate the filing obligation. Wallet, exchange and bank data must therefore support the taxpayer's own calculation.

Costs are recognized annually, not lot-by-lot gain

Documented direct expenditure to acquire virtual currency and documented costs connected with its disposal are deductible under the special rules. All qualifying acquisition costs incurred in a year are reported even if no taxable disposal occurred that year.

If costs exceed revenue, official guidance says taxable income is zero and the excess increases virtual-currency costs in the next year. It is not described as an ordinary tax loss that can be freely offset against salary, securities or general business income. This distinction belongs in the report.

• separate current-year and brought-forward costs;
• exclude financing costs such as loan interest where the official rule denies them;
• do not deduct costs of crypto-to-crypto exchange as a separate disposal cost;
• retain intermediary invoices and exchange-fee evidence;
• carry excess costs forward without inventing a loss expiry.

What changes for an AML-regulated provider?

The statutory exception concerns businesses performing the virtual-currency activities referenced in Article 2(1)(12) of the AML legislation, such as qualifying exchange or intermediation services. Their own facts, authorization/registration position, books, customer transactions and fee income must be evaluated as business activity.

It is not enough that a sole proprietor trades from a business bank account. A software company, consultant or online shop that also buys crypto does not become an AML virtual-currency provider from that investment alone.

Staking, mining, airdrops and DeFi

The special disposal page does not resolve every receipt. Mining services, validator activity, staking rewards, airdrops, lending and liquidity incentives require analysis of how and when the taxpayer obtained the token and whether income arose before its later disposal.

Do not count receipt value and later sale revenue twice without the statutory cost treatment. The Poland staking and DeFi guide separates rewards, principal and token exchanges while leaving uncertain classifications for review.

Futures and perpetuals are not virtual currency merely by label

A cash-settled future or perpetual can be a derivative contract rather than a disposal of virtual currency. Contract terms and settlement determine the Polish category. Open-position events are informational; the report uses closed-position broker P&L, with funding and fees separately documented.

Reconstructing opening time or entry price can improve position evidence but must not replace the exchange's known realized P&L. Missing values remain not determinable.

Evidence and reconciliation

1. Import all exchanges, wallets and bank flows.
2. Pair own transfers and preserve costs.
3. Separate crypto-to-crypto swaps from taxable disposals.
4. Aggregate qualifying annual revenue and direct costs.
5. Carry forward unabsorbed costs from prior PIT-38 returns.
6. Separate rewards, services and derivatives.
7. Reconcile the result to PLN valuations and supporting files.

Exchange exports alone may not meet every bookkeeping need for a regulated provider. The Poland exchange-report guide explains how to preserve IDs, timestamps and bank reconciliation.
