PIT-38 Tax Return -- Step-by-Step Guide for Investors

What Is PIT-38 and Who Needs to File It?

PIT-38 is the Polish tax form for reporting income from capital gains. You must file it if during the tax year you:

• Sold stocks, ETFs, or other securities
• Realized gains or losses on cryptocurrencies
• Received foreign dividends (self-reported)
• Sold shares in companies
• Closed positions on derivative instruments

Deadline for PIT-38 for 2025: April 30, 2026.

Important: even if you only had losses, it's worth filing PIT-38 -- you can deduct losses from gains over the next 5 years.

Where to Get Your Data

PIT-8C from Polish Brokers

Every Polish broker (XTB, mBank, Bossa, DM PKO) is required to send you a PIT-8C information form by the end of February. It contains:

• Revenue from securities sales
• Cost basis (purchase price + commissions)
• Gains or losses

Foreign Brokers

If you use Interactive Brokers, Degiro, or Trading 212, you won't receive PIT-8C. You must independently:

1. Download annual transaction statements
2. Convert each transaction to PLN using the NBP exchange rate from the business day before the transaction
3. Sum up all revenues and costs

This is tedious but mandatory. The NBP rate must be from the business day preceding the transaction date.

Cryptocurrencies

Crypto exchanges (Binance, Bybit, Zonda) don't issue PIT-8C. You must independently:

• Document every buy and sell transaction
• Convert to PLN using the exchange rate from the transaction date
• Include trading fees as costs

How to Fill Out PIT-38 -- Step by Step

Step 1: Gather Documents

• PIT-8C from Polish brokers
• Transaction statements from foreign brokers
• Crypto transaction history
• Commission and transfer confirmations

Step 2: Fill in Section C -- Securities Income

In row 1 (Sale of securities), enter:

• Revenue: total amount from sales
• Cost of revenue: total purchase cost + commissions
• Income/Loss: the difference

Example: You bought an ETF for 10,000 PLN (+ 29 PLN commission), sold for 12,500 PLN (+ 36 PLN commission):

• Revenue: 12,500 PLN
• Costs: 10,000 + 29 + 36 = 10,065 PLN
• Income: 2,435 PLN
• Tax: 2,435 x 19% = 463 PLN

Step 3: Fill in Section D -- Cryptocurrencies

Crypto is reported separately in Section D:

• Revenue from virtual currency sales
• Costs (purchase price, exchange fees, conversion costs)

Important: exchanging one cryptocurrency for another (e.g., BTC to ETH) is not a taxable event in Poland. Tax applies only when converting to fiat currency (PLN, EUR, USD) or purchasing goods/services.

Step 4: Deduct Prior Year Losses

If you had investment losses in previous years (up to 5 years back), you can deduct them:

• Method 1: deduct up to 50% of the loss in one year
• Method 2 (since 2019): one-time deduction up to 5,000,000 PLN

Example: You lost 8,000 PLN on stocks in 2024. In 2025, you gained 12,000 PLN:

• Deduct 4,000 PLN (50% of 8,000)
• Taxable base: 12,000 - 4,000 = 8,000 PLN
• Tax: 8,000 x 19% = 1,520 PLN (instead of 2,280 PLN)
• Savings: 760 PLN

Step 5: Calculate Tax and Submit

Sum all income from Sections C and D, subtract prior year losses, and calculate 19% tax on the result.

You can file:

• Electronically via e-Urzad Skarbowy (Twoj e-PIT portal)
• Through e-Deklaracje software
• On paper at the tax office (not recommended)

Common Mistakes on PIT-38

1. Omitting foreign transactions -- remember stocks bought through foreign brokers
2. Wrong NBP exchange rate -- use the rate from the day before, not the transaction day
3. Not reporting crypto -- mandatory since 2019
4. Forgetting commissions -- broker fees are deductible costs
5. Not reporting losses -- always report losses to use them in future years
6. Missing the deadline -- late filing results in penalties and interest

Simplifying Your Tax Filing

Investing across multiple platforms (XTB, Revolut, Binance, Interactive Brokers) makes tax filing complex. Freenance lets you track all investments in one place -- from stocks and ETFs to crypto. By integrating with popular Polish banks and brokers, it gives you a complete picture of your gains and losses, making PIT-38 preparation significantly easier.

Key Dates to Remember

Summary

PIT-38 isn't as complicated as it seems -- but it requires organization. Key principles:

• Collect documents throughout the year -- don't wait until April
• Remember foreign brokers -- no PIT-8C doesn't mean no obligation
• Report crypto in Section D -- it's a separate category
• Always report losses -- they'll be useful in coming years
• File early -- the e-Tax Office servers get overloaded in late April

Systematic transaction tracking throughout the year is the best strategy for painless tax filing. A tool like Freenance that aggregates all your investment data can make the difference between a stressful April and a smooth one.

Foreign Broker Reporting — Interactive Brokers (IBKR)

Getting Your IBKR Tax Data

Interactive Brokers is the most popular foreign broker among Polish investors, but it doesn't issue PIT-8C. You must generate your own tax report.

Step-by-step:

1. Log in to IBKR Client Portal → Performance & Reports → Statements

2. Select "Activity Statement" → Period: Annual (2025) → Format: CSV or PDF

3. Key sections to extract:

   • Trades: All buy/sell transactions with dates, amounts, and currencies
   • Dividends: All dividend payments received (with withholding tax)
   • Interest: Any interest paid or received
   • Fees: All commissions and fees paid
   • Forex: Currency conversion transactions

4. For tax filing purposes, you also need the "Tax Report" available under Reports → Tax Reports → Tax Information Statement

IBKR Currency Conversion Challenge

The most time-consuming part: Every IBKR transaction is in foreign currency (typically USD or EUR). You must convert each one to PLN using the NBP rate from the business day before the transaction.

Practical approach:

• Download the full transaction list as CSV
• Use a spreadsheet to batch-convert using NBP rates
• Tools like pit38.pl or e-pity can import IBKR statements and handle conversion automatically
• Freenance tracks your portfolio gains — useful when preparing your PIT-38 filing → freenance.io

IBKR Dividend Reporting

US dividends from IBKR:

• IBKR withholds 15% US tax (with W-8BEN form on file)
• Report gross dividend in PIT-38 or PIT-36 (depending on character)
• Claim foreign tax credit for the 15% withheld
• Pay difference between Polish 19% and US 15% = 4% additional tax

Example:

• Received $1,000 in Apple dividends
• IBKR withheld $150 (15% US tax)
• NBP rate: 4.20 PLN/USD
• Polish gross income: 4,200 PLN
• Polish tax due: 4,200 × 19% = 798 PLN
• Foreign tax credit: 150 × 4.20 = 630 PLN
• Net Polish tax: 798 - 630 = 168 PLN

Foreign Broker Reporting — XTB

XTB Tax Reporting (Polish Broker With Foreign Markets)

XTB is a Polish-licensed broker, which means it issues PIT-8C for Polish market transactions. However, foreign market transactions may require additional attention.

What XTB provides:

• PIT-8C for GPW (Warsaw Stock Exchange) trades — automatically sent by end of February
• Annual tax statement for foreign market trades
• Transaction history downloadable as CSV

What you need to do:

• Verify that PIT-8C includes all your transactions
• For CFD trading, ensure gains/losses from contracts for difference are included
• XTB's PIT-8C covers both Polish and foreign stocks traded through the platform
• Currency conversion is handled by XTB in the PIT-8C

XTB-specific tips:

• Check the "Tax Summary" section in your XTB account settings
• Download the annual report before the PIT-8C arrives to verify amounts
• If you traded on both real stocks and CFDs, confirm both are in the PIT-8C
• XTB's fractional shares (synthetic) may be treated differently — verify classification

Loss Carry-Forward Rules — Detailed Explanation

How Investment Loss Deduction Works

Polish tax law allows two methods for deducting investment losses:

Method 1: Standard Deduction (up to 50% per year)

You can deduct up to 50% of your total loss in any single year, spread over up to 5 years.

Example:

• 2024 loss: 20,000 PLN
• 2025 gain: 30,000 PLN → Deduct 10,000 PLN (50% of loss) → Tax on 20,000 PLN
• 2026 gain: 15,000 PLN → Deduct remaining 10,000 PLN → Tax on 5,000 PLN
• Total tax saved: (10,000 + 10,000) × 19% = 3,800 PLN

Method 2: One-Time Deduction (up to 5,000,000 PLN)

Since 2019, you can deduct the entire loss in one year, provided the loss doesn't exceed 5,000,000 PLN.

Example:

• 2024 loss: 20,000 PLN (under 5M limit)
• 2025 gain: 30,000 PLN → Deduct full 20,000 PLN → Tax on 10,000 PLN
• Tax saved: 20,000 × 19% = 3,800 PLN (same amount, but in one year instead of two)

Important Loss Deduction Rules

• Losses from securities (Section C) can only offset securities gains — not crypto gains
• Crypto losses (Section D) can only offset crypto gains — not securities gains
• Losses expire after 5 years — use them or lose them
• You must have filed PIT-38 reporting the loss — unfiled losses cannot be deducted later
• Losses carry forward automatically in the e-PIT system if prior returns were filed electronically

Dividend Tax Treatment in Detail

Polish Dividends (GPW-Listed Companies)

Flat 19% withholding tax — automatically deducted by the broker. No action needed on PIT-38; these are reported separately and are considered "final tax."

Foreign Dividends — Step-by-Step

1. Determine the source country tax treaty rate

• US: 15% (with W-8BEN)
• UK: 0%
• Germany: 26.375%
• Ireland: 25%

2. Convert to PLN

• Use NBP rate from business day before payment date
• Not the ex-dividend date — the actual payment date

3. Calculate Polish tax obligation

• Gross dividend × 19% = Polish tax due
• Minus foreign tax withheld (converted to PLN)
• Pay the difference (if positive)

4. Report correctly

• Foreign dividends go on PIT-36 (not PIT-38) if you're also filing PIT-36
• If PIT-38 is your only return, include in the appropriate section
• Use Attachment PIT/ZG for foreign income reporting

Double Taxation Pitfall

The most common expensive mistake: Paying full 19% Polish tax on dividends where foreign tax was already withheld, without claiming the foreign tax credit. On $10,000 in US dividends, this costs you ~2,500 PLN unnecessarily.

Complete Income Types for PIT-38

Understanding exactly what income must be reported on PIT-38 is crucial for compliance. Here's a comprehensive breakdown:

Capital Gains (Section C)

• Stock sales — individual company shares
• ETF sales — both accumulating and distributing
• Mutual fund redemptions — TFI fund units
• Bond sales — corporate and government bonds (excluding Polish Treasury bonds which are tax-exempt)

• Warrant exercises — employee stock options
• REIT sales — real estate investment trusts
• Commodity ETF sales — gold, oil, agricultural ETFs

Cryptocurrency Income (Section D)

• Crypto spending — buying goods/services with cryptocurrency
• Mining income — reported at market value when mined
• Staking rewards — DeFi and proof-of-stake rewards

Detailed Step-by-Step PIT-38 Filing Guide

Step 1: Organize Your Documents (January-February)

Create a filing system:

• Folder for each broker/exchange
• Separate folders for stocks, crypto, and foreign investments
• Monthly bank statements showing transfers
• Currency conversion records

Download all statements:

• XTB: Go to Reports → Annual Tax Statement
• mBank eMakler: Statements → Tax documents
• Bossa: Reports section
• Interactive Brokers: Reports → Tax Reports → Annual Statement
• Binance: Wallet → Transaction History → Generate Statement
• Bybit: Account → Transaction History

Step 2: Currency Conversion Calculations

For every foreign transaction, you need the NBP (Polish National Bank) exchange rate from the business day before the transaction.

NBP Rate Lookup:

1. Visit nbp.pl → Exchange rates
2. Find the date: day before your transaction
3. If it's a weekend/holiday, use the last business day
4. Use "Table A" rates for major currencies

Conversion formula:

• Purchase cost in PLN = Foreign amount × NBP rate (day before purchase)
• Sale revenue in PLN = Foreign amount × NBP rate (day before sale)

Example calculation:

• Bought 100 shares of AAPL at $150 on March 15, 2025
• NBP USD rate on March 14, 2025: 4.2500 PLN/USD
• Purchase cost: 100 × $150 × 4.2500 = 63,750 PLN
• Sold 100 shares at $180 on June 20, 2025
• NBP USD rate on June 19, 2025: 4.1800 PLN/USD
• Sale revenue: 100 × $180 × 4.1800 = 75,240 PLN
• Capital gain: 75,240 - 63,750 = 11,490 PLN

Step 3: Complete Section-by-Section Filing

Personal Information Section:

• PESEL number

ETF Tax Treatment Details

Accumulating vs Distributing ETFs

Accumulating ETFs (most popular for Polish investors):

• No dividend distributions to report separately
• Tax only when you sell the ETF shares
• Simpler tax reporting
• Examples: VWCE, CSPX, IWDA

Distributing ETFs:

• Quarterly/annual dividend payments subject to tax
• Must report dividends as foreign income if from EU ETFs
• Also report capital gains when selling
• More complex tax situation

ETF Domicile Impact

Irish-domiciled ETFs (most European ETFs):

• Subject to 19% Polish capital gains tax
• No withholding tax at source
• Examples: Vanguard FTSE All-World (IE), iShares Core S&P 500 (IE)

Luxembourg-domiciled ETFs:

• Subject to 19% Polish capital gains tax
• No withholding tax at source
• Less common than Irish ETFs

US-domiciled ETFs (not directly accessible to EU investors):

• Would be subject to US withholding tax if accessible
• Must use EU equivalents instead

REIT ETF Special Considerations

REITs (Real Estate Investment Trusts) held through ETFs have special tax treatment:

• REIT dividends within ETFs are still subject to capital gains tax
• No special real estate tax rates apply
• Report the same as regular ETF sales

Common PIT-38 Mistakes to Avoid

Documentation Errors

• Missing transaction records — keep all broker statements
• Wrong currency conversion dates — use day before, not transaction day
• Incomplete cost basis — include all commissions and fees
• Mixed up tax years — December 31 sale is current year income

Calculation Mistakes

• Using wrong NBP rates — table A for major currencies, table C for others
• Forgetting transaction costs — deduct all broker commissions
• Double-counting losses — each loss can only be used once
• Mixing crypto and securities — separate sections for different asset types

Filing Process Errors

• Missing electronic signature — returns must be properly signed
• Wrong tax office selection — use office based on your residence
• Late submission — April 30 deadline is firm
• Insufficient payment — pay full calculated tax by deadline

Frequently Asked Questions

Do I need to file PIT-38 if I only had losses?

Yes, filing losses allows you to carry them forward for up to 5 years to offset future gains. Even if you owe no tax, filing preserves your ability to use losses in the future.

What if I forgot to file PIT-38 in previous years?

You can file amended returns for up to 5 years. However, late filing penalties may apply. Consult a tax advisor for complex situations involving multiple missed years.

Can I hire someone to prepare my PIT-38?

Yes, tax advisors and accounting firms can prepare PIT-38 returns. Fees typically range from 200-800 PLN depending on complexity. Choose someone experienced with investment taxation.

What if I disagree with tax office interpretation?

You can appeal tax office decisions. First step is filing an objection with the same office. If unsuccessful, you can appeal to administrative courts. Consider professional tax advice for significant amounts.

How do I handle IPO allocations and rights issues?

IPO shares are treated as purchases at the IPO price. Rights issues may or may not trigger taxable events depending on structure. Complex corporate actions often require professional tax advice.

What about employee stock options (ESOP)?

Stock option exercises are generally taxable income at exercise date. Subsequent sale of shares is capital gains. Complex area requiring careful documentation of exercise dates and prices.

Do I need to report IKE/IKZE transactions on PIT-38?

No. Transactions within IKE and IKZE accounts are tax-sheltered and do not appear on PIT-38. You only report IKE/IKZE if you make an early withdrawal (which triggers taxation), but even then it's handled differently — your provider reports it.

How do I handle stock splits on PIT-38?

Stock splits don't trigger a taxable event. Your cost basis per share adjusts proportionally. For example, if you bought 10 shares at 100 PLN each and a 2:1 split occurs, you now have 20 shares with a cost basis of 50 PLN each. Report the adjusted figures when you eventually sell.

What if I received shares as a gift or inheritance?

Gifted shares: your cost basis is the donor's original purchase price. Inherited shares: cost basis is the market value on the date of death (or the probate valuation date). Both are complex — consider professional advice for significant amounts.

Can I file PIT-38 after the April 30 deadline?

You can file late, but penalties apply. Late filing incurs a fine calculated based on the minimum wage (currently 1/30 per day of delay). Additionally, unpaid tax accrues interest at ~8.5% annually from May 1. File as soon as possible to minimize penalties — the tax office may reduce fines for voluntary late filings.

How do I report P2P lending income (Mintos, PeerBerry)?

P2P lending interest from foreign platforms is generally treated as capital income. Report the total interest received (converted to PLN) in Section C of PIT-38. Withholding tax from the platform's country can be credited against Polish tax using the appropriate tax treaty. Keep all statements from the platform as documentation.

What about Revolut stock trading on PIT-38?

Revolut operates through a Lithuanian entity (Revolut Securities Europe UAB). You won't receive a PIT-8C. Download your annual statement from the Revolut app (Stocks → Account Statement), convert all transactions to PLN using NBP rates, and report in Section C of PIT-38. Revolut provides transaction details in EUR, which simplifies the conversion somewhat.

Conclusion

PIT-38 filing doesn't have to be overwhelming with proper preparation and organization. The key is maintaining good records throughout the year and understanding which transactions trigger tax obligations.

Freenance simplifies this process by automatically categorizing investment transactions, tracking gains and losses, and helping you understand your overall tax liability before filing season. Instead of scrambling to reconstruct your investment activity in April, you'll have a clear picture of your tax situation year-round.

Remember: when in doubt, consult a qualified tax advisor. The cost of professional advice is often less than the penalties for incorrect filing or missed opportunities for tax optimization.
