Example Use Case

Marta, a Polish investor, made 200+ stock trades in 2024 through Freedom24, including US and EU stocks. Since Freedom24 is based in Cyprus, it doesn't generate a PIT-8C declaration. So Marta needs to:

1. Match each sale to its original purchase (including partial closures)
2. Convert all foreign amounts to PLN using NBP rates from transaction dates
3. Calculate total income/costs for tax declaration
4. Manually fill the PIT-8C declaration

With pit8c, she simply runs:

pit8c freedom24 annual_report_2024.xlsx

The tool automatically:

• Processes all trades from the XLSX report
• Matches sales with purchases using FIFO
• Applies correct NBP exchange rates (even for weekend trades)
• Generates ready-to-submit PIT-8C (.pdf file)
• Creates audit-ready XLSX with all calculations

No more spreadsheet errors or manual rate lookups. 🚀

Usage

Processing an Annual Report

To process your annual tax report (.xlsx file with all the trades made during the year), use:

pit8c <broker> <tax_report_file>

• broker: the broker’s name (lowercase).
• tax_report_file: the XLSX file with all your trades downloaded from the supported broker.

The tool will:

1. Read the broker’s XLSX file.
2. Convert all trades (buy and sell) into an internal unified structure based on ISIN and currency.
3. Apply FIFO matching to determine partial closures.
4. Compute income and costs for each matched position.
5. Generate PIT-8C PDF report and save it near the input file.
6. Print D section of PIT-8C report to console.
7. Write the closed positions near the input file (for audit).

Example:

pit8c freedom24 annual_report_2024.xlsx
