Mining, issuance and validation fall in Category B. The simplified regime uses 0.15 or 0.95 by activity. A reporting provider communicates by 31 May. The 31 May report covers the preceding calendar year.
Timing and Possible Delays
Set by the tax year and transaction records
The work is planned around the tax year, wallet exports, exchange statements, asset classifications and activity records.
What delays it
The work takes longer when an exchange export is incomplete, wallets cannot be reconciled, received-asset records are missing or the activity spans several countries and tax years.
What to prepare now
Organise your residence, wallet, exchange, activity, foreign-tax and prior-filing records before the work begins.
Wallet Records, Classification and Reporting
The wallet and activity ledger
A certified accountant labels each line by acquisition, disposal, remuneration, mining, issuance or validation so the CIRS category rests on an identifiable transaction history. A certified accountant then separates habitual activity from isolated transactions before applying the relevant reporting treatment.
The evidence for the holding period
A certified accountant links the original acquisition to each later disposal or crypto-for-crypto exchange before applying the 365-day rule and any carried-forward value. You should preserve the export metadata that shows the wallet or exchange source when a transaction history spans multiple platforms.
The provider report and your return
Provider statements are stored with the wallet ledger, and the records that support your own Portuguese IRS return are marked. A certified accountant then checks the provider data against your income and disposal schedule before the agreed return is prepared.
Set out your crypto tax position
State where you lived, which assets and wallets you used, how you received or disposed of crypto-assets and which filings already exist.
