Crypto gains held for more than 365 days are tax-exempt (since 2023). Below that, a 28% rate applies on profit. Must be declared in the IRS (Annex G).

Key points

  • 0% rate for holding > 365 days
  • 28% on short-term gains
  • Declare in IRS Annex G
  • FIFO mandatory by default
  • Law no. 24-D/2022, art. 5

Calculate on your own history

The rate is only half the problem. To file, you need to match each disposal to the right acquisition under FIFO, convert to your currency at the date of each transaction, and separate short-term from long-term. ChainFolioAI does this from your transactions — connect wallets read-only or import a CSV from your exchange — and exports to PDF or Excel.
