Trading Taxes in Portugal: Complete Guide

Portugal’s capital gains tax on securities (mais-valias) is governed by the Código do IRS and administered by the Autoridade Tributária e Aduaneira (AT). For traders, the headline rate is a flat 28% on gains from stocks, ETFs, bonds, and derivatives — but several planning levers, including an aggregation election and a crypto holding exemption, can significantly reduce the effective tax burden.

Who This Applies To

Portugal’s capital gains rules apply to all Portuguese tax residents who trade securities, derivatives, or cryptocurrency. Tax residency is triggered by spending 183 or more days in Portugal during a calendar year, or by maintaining a habitual residence there. This is particularly relevant for digital nomad traders arriving on D8 visas — once the 183-day threshold is crossed, worldwide trading income becomes taxable in Portugal.

The rules cover stocks, ETFs, bonds, CFDs, futures, options, and forex. Both domestic and international brokers are included. Interactive Brokers and Trading 212 are the most popular platforms among Portugal-based traders, with Degiro also widely used.

Key Rules

28% Flat Rate (Código do IRS, Art. 72)

All capital gains from securities fall under Category G income and are taxed at a flat 28% rate by default. This applies to the net gain on each disposal — purchase price is deducted from sale price, and the difference is taxed. Unlike France’s 30% flat tax, Portugal’s rate excludes social contributions from the capital gains calculation.

Aggregation Election (Englobamento)

Residents can opt to aggregate capital gains with all other income and pay progressive IRS rates instead of the flat 28%. The 2024 progressive brackets range from 14.5% to 48%. The break-even point is approximately €28,000 in total taxable income — below that threshold, aggregation produces a lower effective rate. Above it, the flat 28% is typically better. Note that choosing aggregation applies to all Category G income for that tax year, not selectively.

Crypto 365-Day Holding Exemption

Since January 2023 (Lei 24-D/2022, Art. 233), cryptocurrency gains are taxed at 28% if the asset is sold within 365 days of acquisition. Crypto held for more than one year is completely exempt from capital gains tax. This creates a clear planning lever: timing disposals to exceed the 365-day mark eliminates the tax entirely. Exempt gains are still reported on Anexo G1 for transparency. For more on crypto trading taxes, see the dedicated guide.

Derivatives and Forex at 28%

CFDs, futures, options, and forex spot trades are all taxed identically at the 28% flat rate. Losses within Category G can offset gains in the same tax year, but cannot be carried forward to subsequent years or offset against other income categories. A trader with €8,000 in CFD gains and €3,000 in CFD losses pays 28% on the net €5,000 (€1,400).

NHR Closure and IFICI Replacement

The Non-Habitual Resident (NHR) regime offered 0% tax on foreign-source capital gains for 10 years — a major draw for relocating traders. It closed to new applicants on January 1, 2024. The replacement IFICI incentive (Incentivo Fiscal à Investigação Científica e Inovação) provides a 20% flat rate on qualifying employment and self-employment income, but explicitly excludes passive investment income. For traders, IFICI offers no benefit on trading gains.

Anexo G Filing Deadline

Taxable gains are reported on IRS Anexo G, submitted as part of the annual IRS declaration by June 30 following the tax year. Exempt gains (such as crypto held over 365 days) are reported separately on Anexo G1.

Practical Examples

Digital nomad trader in Lisbon: A US-based trader moves to Lisbon on a D8 visa in March 2025, trading US stocks via Interactive Brokers and holding 2 BTC purchased in 2023. In her first Portuguese tax year, she realizes €15,000 in stock trading gains and sells 1 BTC for a €20,000 gain (held over 365 days). The BTC gain is fully exempt and reported on Anexo G1. For the €15,000 in stock gains, she compares the flat 28% (€4,200) against aggregation with her €22,000 freelance income — a total of €37,000 taxed at a blended rate of roughly 25%, producing approximately €3,750 on the gains portion. She elects aggregation, saving €450. Had she qualified for the now-closed NHR regime, the foreign-source stock gains would have been taxed at 0% — a €4,200 annual difference.

CFD trader offsetting losses: A Lisbon-based trader realizes €12,000 in CFD gains and €5,000 in CFD losses during 2025. The net taxable gain is €7,000, taxed at 28% for a total of €1,960. Unlike Spain, Portugal has no equivalent of the Modelo 720 foreign asset reporting requirement, and unlike the US wash sale rule, there are no restrictions on repurchasing sold positions.

Crypto timing strategy: A trader buys ETH in February 2025 for €10,000 and it appreciates to €18,000 by January 2026. If she sells in January (within 365 days), she owes 28% on the €8,000 gain (€2,240). By waiting until March 2026 (past the 365-day mark), the entire gain is exempt. For active crypto traders, tax-loss harvesting on short-held positions can offset gains on other short-held disposals.

How JournalPlus Helps with Compliance

JournalPlus tracks every trade with precise timestamps and calculates holding periods automatically, making it simple to identify which crypto positions have crossed the 365-day exemption threshold. This removes guesswork from the most valuable tax planning decision Portuguese crypto traders face.

The tax report export separates Category G taxable gains from Anexo G1 exempt gains, matching the format required by the Autoridade Tributária. Traders can export a clean summary of net gains and losses by asset class, broken down by stocks, derivatives, and crypto — ready for a contabilista certificado to review.

For tax-conscious traders using the aggregation election, JournalPlus provides running year-to-date gain totals so traders can model whether the flat 28% or progressive rates will produce a lower tax bill before the year ends.

Frequently Asked Questions

What is the capital gains tax rate for traders in Portugal?

Portugal applies a flat 28% tax on capital gains from securities under Category G income (Código do IRS, Art. 72). Residents can elect aggregation (englobamento) to be taxed at progressive rates from 14.5% to 48%, which produces savings when total taxable income falls below roughly €28,000.

Is cryptocurrency trading tax-free in Portugal?

Not entirely. Since January 2023, crypto sold within 365 days of purchase is taxed at the standard 28% flat rate. However, crypto held for more than 365 days remains fully exempt from capital gains tax under Lei 24-D/2022, Art. 233 — reported on Anexo G1 for transparency but generating zero tax liability.

Does Portugal have a wash sale rule?

No. Portugal has no equivalent of the US wash sale rule, no stamp duty on electronic trades, and no wealth tax. Traders can sell a position at a loss and immediately repurchase the same security without the loss being disallowed, making Portugal more flexible than many jurisdictions for tax-loss harvesting strategies.

What happened to Portugal’s NHR tax regime for traders?

The Non-Habitual Resident regime closed to new applicants on January 1, 2024. It previously offered 0% tax on foreign-source capital gains for 10 years. The replacement IFICI incentive provides a 20% flat rate on qualifying employment income but does not cover passive investment gains — a significant downgrade for relocating traders.

When do digital nomad traders become tax residents in Portugal?

Traders on a D8 digital nomad visa become Portuguese tax residents after spending 183 or more days in the country during a calendar year. Once this threshold is crossed, worldwide income — including all foreign trading gains — becomes subject to Portuguese taxation and must be reported via the annual IRS declaration by June 30.
