About Taxbordr: founder-led crypto tax advisory
Taxbordr is a Lisbon-based cross-border tax advisory founded by Telmo Ramos, member of the Ordem dos Economistas, Cédula nº 16379. Telmo trained at KPMG Luxembourg and EY Lisbon. He founded Taxbordr in 2022. The firm has handled 250+ cross-border cases including pre-2023 holders relying on the old exempt regime, post-2023 Cat E / Cat G / Cat B classifications, miner Cat B / SS positions, NFT disposals, DeFi yield reporting on Anexo E, and US Form 1099-DA reconciliations. Every crypto position goes out under his name with documented FIFO basis and category mapping.
The three categories
Category G (capital gains). Disposals of crypto held by a private individual. Legal basis: CIRS art 10 n.º 1 al. k) (introduced by Lei 24-D/2022 effective 1 January 2023). Rate: 28% autonomous per CIRS art 72 below 365-day holding; exempt at or above 365 days. Excluded from exemption: crypto issued by entities resident in blacklisted jurisdictions (Portaria 150/2004), taxable at higher rates regardless of holding period. Crypto-to-crypto swaps are NOT realisation events under the Portuguese rule; basis carries; the holding period for the new asset starts at the swap date for the new-asset 365-day clock.
Category E (capital income / passive yield). Staking rewards, lending interest, liquidity-pool yield, DeFi protocol yield. Taxable at 28% flat per CIRS art 72 at receipt, regardless of any holding period of the underlying asset. No 365-day exemption applies to Cat E. Receipt timing follows the protocol mechanics (each reward distribution is a Cat E event in EUR-equivalent at the date of receipt).
Category B (business income / regular activity). Regular and systematic crypto trading, organised mining, professional market-making. Progressive IRS rates per CIRS art 68 plus Segurança Social contributions per Código Contributivo (typically 21.4% on 70% of declared turnover). The "regular and systematic" test is fact-based: frequency of trades, organisational structure, dedicated equipment (mining), client-facing activity, and time devoted. Day-trading at scale typically qualifies; occasional disposals do not.
The 365-day rule (Cat G specifically)
For Cat G disposals by a private investor:
Less than 365 days: 28% flat autonomous, with optional aggregation (englobamento) at progressive rates if it produces a lower outcome
365 days or more: exempt, provided the asset is not from a blacklisted jurisdiction and is not classified as a security token under CIRS rules
The holding period is calculated per disposal on a FIFO basis
Crypto-to-crypto swaps reset the holding period for the new asset (the new-asset 365-day clock starts on the swap date), but the swap itself is not a Cat G realisation event under the current PT rule
Bitcoin specifically
Bitcoin is treated under the same three-category framework as any other cryptoasset. There is no Bitcoin-specific carve-out. The classification depends on the activity, not the asset:
Bitcoin held by a private investor and disposed of after 1+ year: Cat G, exempt
Bitcoin sold within 365 days: Cat G, 28% autonomous
Bitcoin staking or lending yield: Cat E, 28% at receipt
Bitcoin mining (organised): Cat B, progressive + SS
Reporting on Modelo 3
Cat G crypto disposals: Anexo G1 (line for crypto disposals); each disposal reported with acquisition date, disposal date, EUR-equivalent gain
Cat E crypto yield: Anexo E (capital income); each receipt date, gross amount, withholding tax if any
Cat B activity: Anexo B (simplified regime) or Anexo C (organised accounting); Recibos Verdes invoicing for Portuguese-source revenue
Foreign-exchange gains in EUR: all amounts converted at the AT-published or BdP reference rate for the date of the event
IFICI for crypto-active residents
Foreign-source Cat G crypto gains can be exempt under IFICI's exemption method (CIRS art 81 n.º 4) where the regime applies. Cat E foreign-source likewise. Cat B is taxed at the IFICI 20% rate where the activity falls within qualifying CAE codes per Portaria 352/2024/1; otherwise standard rates apply. Blacklisted-jurisdiction issuers are excluded from exemption per CIRS art 81 n.º 5.
US-side reporting (US persons)
For US persons resident in Portugal:
IRS treats crypto as property; report disposals on Form 8949 and Schedule D
Form 1099-DA: mandatory broker reporting from 1 January 2025; basis reporting from 2026 (per IRS final regs)
FBAR (FinCEN 114) and Form 8938 thresholds may apply to custodial wallets at foreign exchanges
US tax on the same gains under the Saving Clause; recover Portuguese tax via FTC on Form 1116
Wash-sale rules do not currently apply to crypto on the US side, but proposed legislation has been pending
Common mistakes
Treating staking yield as Cat G (it is Cat E and not subject to the 365-day exemption)
Aggregating crypto disposals (englobamento) when 28% autonomous is the better result
Failing to test for Cat B classification when activity is regular and systematic
Missing the blacklist-jurisdiction exception for IFICI exemption
Treating crypto-to-crypto swaps as taxable events (they are not realisation events under current PT rules)
Forgetting to convert each event to EUR at the AT or BdP reference rate (a year-end reconstruction is rarely defensible)
Treating pre-2023 holdings as still exempt under the old regime (the old exemption position ended with Lei 24-D/2022)

Frequently Asked Questions
Is crypto taxable in Portugal?
Yes, since 1 January 2023 under Lei 24-D/2022. Three categories: Cat G (private capital gains), Cat E (passive yield), Cat B (regular activity). Cat G holdings ≥ 365 days are exempt; below 365 days taxed at 28% autonomous (CIRS art 72). Cat E (staking, lending) is 28% flat at receipt with no 365-day rule. Cat B is progressive plus Segurança Social.
How does the 365-day crypto holding rule work in Portugal?
For Cat G private-investor disposals, holdings ≥ 365 days are exempt; below 365 days taxed at 28% autonomous per CIRS art 72. The holding period is calculated per disposal on FIFO basis. Excludes crypto from blacklisted jurisdictions and security-classified tokens. The rule applies only to Cat G; staking yield (Cat E) and regular-activity gains (Cat B) do not qualify regardless of holding period.
How is staking and DeFi yield taxed in Portugal?
As Category E (capital income) at 28% flat at receipt per CIRS art 72, regardless of any holding period of the underlying asset. Each reward distribution is a Cat E event in EUR-equivalent at the date of receipt. Reported on Anexo E. The 365-day exemption does not apply.
Are crypto-to-crypto swaps taxable in Portugal?
Under current PT rules, crypto-to-crypto swaps are not realisation events for Cat G; basis carries from the old asset to the new asset. The 365-day holding clock for the new asset starts at the swap date. Swaps for FIAT (EUR, USD, etc.) are realisation events.
Do Portuguese rules treat Bitcoin differently from altcoins?
No. Bitcoin is treated under the same three-category framework as any other cryptoasset. There is no Bitcoin-specific carve-out. Classification depends on the activity (private holding vs staking vs regular trading vs mining), not on the asset.
How does IFICI affect crypto taxation?
Foreign-source Cat G crypto gains are exempt under the IFICI exemption method per CIRS art 81 n.º 4 (EBF art 58-A), with mandatory aggregation for rate calculation. Cat E foreign-source likewise. Cat B at the IFICI 20% rate where the activity falls within qualifying CAE codes per Portaria 352/2024/1. Blacklisted-jurisdiction issuers are excluded from exemption.
What is Form 1099-DA and how does it affect Portuguese-resident US persons?
Form 1099-DA is the new IRS broker reporting form for digital assets. Mandatory broker reporting started 1 January 2025; basis reporting from 2026 per IRS final regulations. US persons resident in Portugal will receive 1099-DA from US-based exchanges and must reconcile against Form 8949 / Schedule D. The Portuguese-side reporting on Anexo G1 / Anexo E / Anexo B remains unchanged.
When does crypto activity qualify as Cat B in Portugal?
When the activity is regular and systematic. The test is fact-based: trade frequency, organisational structure, dedicated equipment (mining), client-facing activity, time devoted. Day-trading at scale typically qualifies. Occasional disposals do not. Cat B triggers progressive IRS rates plus Segurança Social contributions and may require Recibos Verdes registration.
