Portugal introduced a dedicated crypto tax framework through the 2023 State Budget (Law No. 24-D/2022), effective 1 January 2023, ending its former reputation as a European "crypto tax haven" where individual crypto gains were not specifically taxed. The new regime applies a 28% flat rate on short-term capital gains (assets held less than 365 days) while maintaining a full exemption for long-term gains (365 days or more), along with exemptions for crypto-to-crypto swaps and NFT transactions. Crypto service providers are regulated through the Banco de Portugal's VASP registration regime, which is now transitioning to MiCA under Law No. 69/2025.
On the regulatory side, Banco de Portugal authorises CASPs and supervises stablecoin issuers and AML/CFT compliance, while the CMVM (Comissão do Mercado de Valores Mobiliários) supervises the issuance of non-stablecoin crypto-assets and CASPs' business-conduct obligations, alongside its long-standing oversight of tokenized securities. Law No. 69/2025 (MiCA) and Law No. 70/2025 (Transfer of Funds Regulation), both published in December 2025, implement MiCAR and the EU TFR in Portugal, with existing Banco de Portugal registrants given until 1 July 2026 (or the date of a final decision on their MiCA application, whichever is earlier) to obtain full MiCAR authorization. A figure of "seven companies having obtained CASP status as of early 2026, including Mercado Bitcoin" was carried from the taxation source domain but could NOT be confirmed against a live register: the ESMA central CASP register (interim CSV, last published Dec 2024 snapshot) lists no CASP with Portugal as home Member State, and the Banco de Portugal register page was not fetchable (HTTP 403) on 2026-06-06 (see Verification Notes).
From 1 January 2026, Reporting CASPs (RCASPs) operating in the EU must collect crypto transaction data for reporting to Portuguese tax authorities (Autoridade Tributária e Aduaneira, AT) under DAC8, transposed domestically by Law No. 26/2026 of 3 June 2026, with the first report to the AT due by 31 May 2027 (covering 2026) and first CARF international exchange in 2027 -- a significant step for a jurisdiction that had no crypto-specific tax rules before 2023.
1. Regulatory Architecture
Portugal distributes crypto oversight across three authorities:
| Authority | Full Name | Role |
|---|---|---|
| Banco de Portugal | Banco de Portugal | Authorises CASPs; supervises stablecoin issuers and AML/CFT compliance; supervises VASP-to-MiCA transition |
| CMVM | Comissão do Mercado de Valores Mobiliários | Securities market regulator; supervises issuance of non-stablecoin crypto-assets, CASP business-conduct obligations, and tokenized securities |
| AT | Autoridade Tributária e Aduaneira | Tax authority; enforces crypto tax obligations; receives DAC8 CASP reports |
Primary legislation:
| Statute / Instrument | Function |
|---|---|
| 2023 State Budget (Law No. 24-D/2022, 30 December 2022) | Introduced the crypto tax framework; amended CIRS to include crypto across Categories B, E, and G |
| CIRS (Personal Income Tax Code) | Governs individual crypto taxation across three income categories |
| CIRC (Corporate Income Tax Code) | Applicable to corporate entities holding or trading crypto (19% standard mainland rate for FY beginning on/after 1 Jan 2026; SMEs 15% on first EUR 50,000) |
| MiCA Regulation (EU 2023/1114) | Applicable in Portugal from 30 December 2024 |
| Law No. 69/2025 (published December 2025) | Implements MiCAR in Portugal; designates competent authorities; establishes transitional rules |

| Law No. 26/2026 (3 June 2026, Diário da República 1st series No. 107) | Transposes DAC8 (Directive EU 2023/2226 / OECD CARF) and DAC9 (Directive EU 2025/872); amends CIRS, RGIT, and Decree-Law No. 61/2013 |
| Código do Imposto do Selo (Stamp Duty Code) | Potential 10% stamp duty on crypto donations |
VASP-to-MiCA transition timeline:
| Date | Development |
|---|---|
| Pre-2023 | No crypto-specific tax rules; de facto 0% regime for individuals |
| 1 January 2023 | 2023 State Budget crypto tax framework takes effect |
| 30 December 2024 | MiCA Regulation takes effect across the EU |
| December 2025 | Law No. 69/2025 (MiCA) and Law No. 70/2025 (TFR) published in Portugal |
| 1 January 2026 | DAC8 / CARF data collection by RCASPs begins |
| 3 June 2026 | Law No. 26/2026 transposes DAC8/CARF and DAC9 into Portuguese law |
| 1 July 2026 | Deadline for existing VASPs to obtain full MiCAR authorization (or earlier final decision) |
| 31 May 2027 | First RCASP report to the AT due (covering 2026); first CARF international exchange in 2027 |
2. Tax Reporting Obligations
Annual IRS Tax Return (Modelo 3)
Since 2024, individuals must report crypto transactions in the annual IRS tax return:
| Income Category | Form | Tax Treatment |
|---|---|---|
| Category G -- Capital Gains | Annex G | 28% flat rate on short-term gains (< 365 days); 0% on long-term gains (365+ days) |
| Category E -- Investment Income (staking, lending) | Annex E | 28% flat rate; in-kind staking rewards taxed only upon conversion to fiat |
| Category B -- Business Income (mining, issuance) | Annex B | Progressive rates (14.5%-48%) on 15% of gross income (simplified regime, coefficient 0.15) |
Filing deadline: Generally April-June of the following year.
Important: Exempt long-term gains must still be reported -- "tax-free" does not mean "no reporting."
Tax Rate Summary
| Scenario | Rate | Conditions |
|---|---|---|
| Short-term capital gains (< 365 days) | 28% | Autonomous flat rate |
| Long-term capital gains (365+ days) | 0% (exempt) | Non-blacklisted jurisdictions only |
| Gains linked to tax haven blacklist | 35% | No holding period exemption applies |
| Staking/lending income (Category E) | 28% | 35% if blacklisted jurisdiction |
| Mining income (simplified regime) | Progressive (14.5%-48%) on 15% of gross | Coefficient 0.15; only 15% of revenue taxable |
| Corporate crypto gains (IRC) | 19% | Standard mainland rate for FY beginning on/after 1 Jan 2026 (reduced from 21% in 2024 / 20% in 2025); SMEs 15% on first EUR 50,000 |
| Crypto-to-crypto swaps | Not taxable | Explicitly exempt |
| NFT transactions | Not taxable | Expressly excluded from crypto tax regime |
Aggregation Option (Englobamento)
Taxpayers may opt to aggregate crypto capital gains with other income and apply progressive IRS rates (14.5%-48%) instead of the 28% flat rate. This may benefit taxpayers whose marginal rate is below 28%. Critically, loss carryforward (5 years) is only available if aggregation is elected.
CASP Reporting Obligations
Reporting CASPs (RCASPs) registered or operating in Portugal must, under Law No. 26/2026 (DAC8/CARF transposition), collect reportable user and transaction data from 1 January 2026 and submit the first annual report to the AT by 31 May 2027 (covering the 2026 calendar year), and by 31 May of each year thereafter. The statutory text quoted by Portuguese sources reads: "A comunicação assume periodicidade anual, devendo ser efetuada até ao dia 31 de maio de cada ano e reportar-se ao ano civil anterior, prevendo-se que a primeira comunicação, relativa ao ano de 2026, deva ocorrer até 31 de maio de 2027." The previously asserted "31 January of the following year" deadline is incorrect and is retired (it never appeared in the DAC8/CARF transposition). Reports must include full user identification (name, address, NIF, date and place of birth) and transaction detail (purchases, sales, exchanges, crypto payments, transfers to external wallets) with gross amounts and fair market value. Non-compliance carries fines ranging from EUR 2,000 to EUR 22,500 for registration/reporting failures.
DAC8 Automatic Reporting (from 2026; first report 2027)
Under the DAC8 directive (Directive EU 2023/2226 / OECD CARF), transposed domestically by Law No. 26/2026 of 3 June 2026:
- RCASPs operating in the EU collect reportable crypto transaction data from 1 January 2026
- Portuguese AT will receive the first RCASP report by 31 May 2027 (covering 2026), and automatic reports on Portuguese residents' crypto activities from all EU-based CASPs
- Data includes capital gains, staking income, wallet activity, and account balances
- First CARF international exchange covering 2026 transactions in 2027
Enforcement
| Violation | Penalty |
|---|---|
| Late filing | Surcharges and interest under general tax rules |
| Non-declaration of crypto (even exempt gains) | Penalties under the RGIT (General Tax Infringement Regime) |
| AML violations by VASPs | Significant fines for non-compliance with KYC/AML obligations |
| Tax evasion | Subject to RGIT criminal and administrative penalties |
3. Regulatory Direction
Portugal is on an alignment trajectory -- moving from its former outlier position (zero crypto tax, minimal regulation) to mainstream EU compliance through MiCA adoption and DAC8 reporting, while preserving some competitive features for long-term holders.
Near-term developments:
- 1 July 2026 deadline: Existing VASPs registered with Banco de Portugal must obtain full MiCAR authorization (or earlier final decision) or cease operations
- DAC8 data flow: Law No. 26/2026 (3 June 2026) transposes DAC8/CARF; first RCASP report to the AT due 31 May 2027 and first CARF international exchange in 2027, covering 2026 data
- NHR closure / IFICI (NHR 2.0): The original Non-Habitual Resident regime closed to new applicants on 1 January 2024. The replacement IFICI is targeted at highly qualified professionals in scientific research and innovation -- it does not benefit crypto investors, removing a former attraction for international crypto-focused relocations
- Enforcement capacity maturing: Portugal's enforcement infrastructure for crypto tax compliance is still developing, having only existed since 2023
Distinctive features:
- The combination of 365-day holding period exemption with crypto-to-crypto non-taxability preserves significant appeal for buy-and-hold strategies, despite the end of the zero-tax era
- The mining simplified regime (coefficient 0.15) is extremely favorable -- effectively taxing only 15% of gross mining income
- In-kind staking rewards are not taxed at receipt; taxation is deferred until conversion to fiat, reducing cash-flow pressure on stakers
- NFT transactions are expressly excluded from the crypto tax regime
- The 35% blacklisted jurisdiction rate, with denial of the holding period exemption, adds complexity for transactions involving listed tax havens
- Retroactive holding period calculation from the original acquisition date (even before 2023) was a fair transition provision for long-term holders
Portugal's evolution:
| Period | Status | Key Feature |
|---|---|---|
| Pre-2023 | De facto crypto tax haven | No specific tax rules; AT generally did not tax individual crypto gains |
| 2023 | Tax framework introduced | 28% short-term rate; 365-day exemption; Category B/E/G classification |
| 2024 | Mandatory reporting begins | Crypto transactions must be declared on Modelo 3 tax return |
| 2025 | MiCA transposition | Law No. 69/2025 (MiCA) and Law No. 70/2025 (TFR) implement MiCAR; designate competent authorities |
| 2026 | DAC8 transposed | Law No. 26/2026 (3 June 2026) transposes DAC8/CARF; RCASP data collection from 1 Jan 2026, first AT report 31 May 2027 |
4. Recent Developments (since 2026-03-20)
-
3 June 2026 — Law No. 26/2026 transposes DAC8/CARF and DAC9. Published in the Diário da República, 1st series, No. 107, Law No. 26/2026 transposes Directive (EU) 2023/2226 (DAC8 / OECD Crypto-Asset Reporting Framework) and Directive (EU) 2025/872 (DAC9 / Pillar Two information exchange), amending the CIRS, the RGIT, and Decree-Law No. 61/2013. It does not change IRS or IRC rates; RCASP data collection runs from 1 January 2026 with the first report to the AT due 31 May 2027 (covering 2026) and the first CARF international exchange in 2027. Non-compliance fines range from EUR 2,000 to EUR 22,500. (Madeira Corporate Services · Regfollower)
-
MiCA supervisory split confirmed. Under Law No. 69/2025 (MiCA) and Law No. 70/2025 (TFR), Banco de Portugal authorises CASPs and supervises stablecoin issuers, while the CMVM supervises issuance of non-stablecoin crypto-assets and CASPs' business-conduct obligations. Existing VASPs may operate until 1 July 2026 or the date of a final decision on their MiCA application, whichever is earlier. (DLA Piper · Banco de Portugal)

Verification Notes
Reconciled on 2026-06-04 against the refreshed source-domain file content/deep-research/digital-asset-taxation/regulations/europe/portugal.md (modified 2026-06-04) and verified against primary/secondary regulator sources.
Corrections made during the 2026-06-04 reconciliation (Correction Protocol):
- Corporate IRC rate corrected from 21% to 19%. The 2026 State Budget set the standard mainland IRC headline rate at 19% for financial years beginning on or after 1 January 2026 (21% in 2024, 20% in 2025, scheduled to fall further to 18%/17%); qualifying SMEs are taxed at 15% on the first EUR 50,000. Corrected in Sections 1 (legislation table) and 2 (Tax Rate Summary) to match the taxation source-domain file. Verified via PwC Tax Summaries.
- CASP reporting deadline corrected from "31 January of the following year" to "31 May 2027". Under Law No. 26/2026, the first RCASP report to the AT is due 31 May 2027 for 2026 activity. The prior "31 January" date could not be confirmed against any primary source for the DAC8/CARF regime and is treated as NOT VERIFIED. Verified via Madeira Corporate Services and Regfollower.
- DAC8 framing corrected. The file previously described DAC8 only as "effective 1 January 2026". The domestic transposition is Law No. 26/2026 of 3 June 2026; added across Sections 1, 2, 3 and the new Section 4.
- MiCA implementation completed. Added Law No. 70/2025 (TFR) alongside Law No. 69/2025 (MiCA) and clarified the Banco de Portugal / CMVM supervisory split (BdP authorises CASPs and supervises stablecoins; CMVM supervises non-stablecoin issuance and CASP conduct) and the "earlier final decision" qualifier on the 1 July 2026 deadline.
Targeted gap-closure pass (2026-06-06):
- CASP count "seven companies … including Mercado Bitcoin" — gap remains OPEN; wording sharpened. Attempted to re-count authorised Portuguese CASPs against a live register. The ESMA central CASP register (interim CSV, https://www.esma.europa.eu/sites/default/files/2024-12/CASPS.csv, last-published Dec-2024 snapshot — fetched 2026-06-06) lists no CASP with Portugal (PT) as home Member State; the only PT-associated entries are Spanish-authorised firms (BBVA, Openbank, CNMV) passporting in. The Banco de Portugal VASP/CASP register page (https://www.bportugal.pt/en/page/registration-virtual-assets-service-providers) and the MiCA press release returned HTTP 403 and could not be fetched. The "seven companies" figure therefore could not be confirmed against any live register; the intro now states this explicitly. The ESMA snapshot is stale (predates Portugal's MiCA implementation under Law 69/2025), so its zero count is NOT evidence the figure is wrong — it simply cannot corroborate it. Treated as NOT VERIFIED.
- CASP reporting deadline "31 January of the following year" — definitively RETIRED; replaced 31 May 2027 corroborated by verbatim statutory text. Two Portuguese sources reproduce/quote the Law No. 26/2026 statutory wording: SAPO/Lusa ("os prestadores de serviços de criptoativos devem comunicar à AT, todos os anos, a partir deste ano e até ao dia 31 de maio") and TOF Advogados, which quotes the provision verbatim: "A comunicação assume periodicidade anual, devendo ser efetuada até ao dia 31 de maio de cada ano e reportar-se ao ano civil anterior, prevendo-se que a primeira comunicação, relativa ao ano de 2026, deva ocorrer até 31 de maio de 2027." The "31 January" date is confirmed incorrect for the DAC8/CARF regime and is retired in Section 2. NOTE: this corroboration is from a national press agency and a law firm (secondary, Priority 6/8). The Diário da República primary text (diariodarepublica.pt detalhe page for Lei 26/2026) is JS-rendered and returned no fetchable body on 2026-06-06, so a fetched-primary close was not achieved; the gap is downgraded to primary-known-but-unfetchable. Sources fetched: SAPO/Lusa, TOF Advogados.
Not verified / data gaps:
- The "seven companies obtained CASP status as of early 2026, including Mercado Bitcoin" count is carried from the taxation source-domain file (sourced to DLA Piper / Lightspark) and could not be re-counted against a live Banco de Portugal / CMVM / ESMA register (see 2026-06-06 pass above) — NOT VERIFIED.
- Portugal does not publish a CASP application or licence fee schedule, minimum-capital figure, or surety-bond requirement specific to this licence in the sources reviewed; MiCA capital requirements apply at the EU level by service class (NOT independently verified here — see EU-level MiCA references).
- The 10% Stamp Duty application to crypto donations and any parent-child exemption remain only partially clarified in primary guidance (NOT fully VERIFIED).
- DeFi-specific tax treatment remains without dedicated AT guidance (NOT VERIFIED); general-principles inference retained from the source domain.
