Portugal Crypto Tax Guide 2026
Filing Portugal crypto taxes? Learn how Portugal taxes crypto in 2026, including the 365-day rule, 28% rate, staking, mining, Modelo 3, and Anexo G reporting.

Portugal generally taxes short-term crypto gains when you sell or spend crypto after holding it for fewer than 365 days, often at the 28% autonomous rate. Qualifying gains and losses from crypto held for 365 days or more are generally excluded, while crypto-to-crypto trades are usually deferred rather than taxed immediately.
That makes Portugal favorable for some long-term crypto investors, while several activities can still create tax, Stamp Duty, or reporting obligations. Staking, mining, business activity, gifts, NFTs, DeFi, and Modelo 3 (Form 3) reporting can all change the result.
Quick answer
Portugal taxes crypto through different IRS categories depending on what happened. In Portugal, IRS means Imposto sobre o Rendimento das Pessoas Singulares, the individual income tax system.
- Sell or spend crypto after holding it for fewer than 365 days: usually a Category G capital gain or loss, with positive short-term gains generally taxed at 28%.
- Sell qualifying crypto held for 365 days or more: gains and losses are generally excluded from IRS.
- Trade one crypto for another crypto: usually deferred, with the acquisition value carried into the crypto you receive.
- Earn passive staking, lending, or other crypto-paid Category E rewards: generally deferred with zero acquisition value until later disposal.
- Mine or validate crypto: usually review Category B business or professional income first. Non-habitual mining can instead be reviewed under Category G, with no tax at receipt and later disposal analysis.
- Receive a crypto-asset airdrop: the category depends on why you received it, but crypto-asset airdrops generally do not create receipt-side tax. A later disposal or conversion can create Category G tax unless the 365-day exclusion applies.
- Receive crypto as a gift or inheritance: check Stamp Duty rules, not just IRS.
- Report crypto through Modelo 3 (Form 3) and the relevant annexes, usually Anexo G (Annex G), Anexo G1 (Annex G1), Anexo B (Annex B), Anexo E (Annex E), or Anexo J (Annex J).

Is crypto taxed in Portugal?
Yes. Portugal taxes crypto when a transaction falls into a taxable category under the Portuguese IRS rules or the Stamp Duty rules.
For most individual investors, the main category is Category G, which covers capital gains from onerous disposals of crypto-assets that are not securities. A sale for EUR is the clearest example. Spending crypto on goods or services can also be a disposal because you exchange crypto for non-crypto consideration.
Portugal also has two other important income categories:
- Category E: certain capital income, including remuneration from crypto-asset operations. When that remuneration is paid in crypto, Portugal's Article 5 rule generally defers taxation until the later disposal of the received crypto.
- Category B: business or professional income, including habitual mining, validation, or professional crypto activity.
Stamp Duty can apply to gratuitous transfers, including crypto gifts and inheritances. That is separate from whether a later sale creates an IRS capital gain.
What changed for Portugal crypto taxes in 2026?
Two current-law points matter for 2026 Portugal crypto tax filing.
First, Decreto-Lei n.º 97/2026 of May 20, 2026 renumbered parts of CIRS Article 10. The current AT version of CIRS Article 10 places the main crypto rules in Article 10(20) through Article 10(25):
- Article 10(20): definition of crypto-asset.
- Article 10(21): unique and non-fungible crypto-assets are excluded from that definition for this special regime.
- Article 10(22): gains and losses from qualifying crypto held for 365 days or more are excluded.
- Article 10(23): crypto-for-crypto exchanges are generally not taxed at the swap moment, with acquisition value carried into the asset received.
- Article 10(24): the long-term exclusion and deferral can be denied when the taxpayer or counterparty is outside the required EU, EEA, treaty, or information-exchange network.
- Article 10(25): loss of Portuguese tax residence can create a deemed disposal.
Second, CIRS Article 124-A was amended by Lei 26/2026 on June 3, 2026. The current rule requires reporting crypto-asset service providers subject to the referenced reporting regime to report information to AT by May 31 each year for the prior calendar year.
Can AT see your crypto?
AT visibility is increasing. Current CIRS Article 124-A requires covered reporting crypto-asset service providers to report certain information to the Autoridade Tributária e Aduaneira by May 31 for the prior calendar year.
This reporting is Portugal's implementation of DAC8, the EU directive (Directive (EU) 2023/2226) that incorporates the OECD Crypto-Asset Reporting Framework (CARF). Covered crypto-asset service providers report account and transaction information for Portugal-resident users, and tax authorities automatically exchange that information across the EU and CARF partner jurisdictions.
AT visibility still has practical limits. Coverage depends on the provider, the facts, and the reporting regime, especially for self-custody wallets, DeFi interactions, and platforms outside the EU and CARF reporting network. Your filing obligation remains separate: a transaction can be reportable on Modelo 3 even if a platform does not report it directly to AT.
Good records matter more as reporting expands. If AT receives platform information, your return should be able to reconcile the transaction history, cost basis, holding period, fees, and category treatment.
How much crypto tax do you pay in Portugal?
Short-term taxable Category G crypto gains are generally taxed at the 28% autonomous rate. This rate applies to the positive balance of gains and losses from the relevant transactions unless the taxpayer elects aggregation, known as englobamento.
Aggregation can move crypto gains into Portugal's progressive IRS rates. It can also matter for losses because the five-year carry-forward for certain Category G losses is available only when the taxpayer elects, or is required to use, aggregation. That choice depends on the taxpayer's broader income, losses, residence status, and filing position.
Category B income has a different system. Under the simplified regime, Article 31 applies coefficients to determine taxable income. Habitual mining income uses a 0.95 coefficient. Other crypto operations within the simplified-regime rules can use a 0.15 coefficient. Category B taxpayers need more tailored advice because business classification changes the return, the records you must keep, and can trigger Portuguese social security contributions for self-employed taxpayers.
Category E crypto remuneration has its own timing rule. When the remuneration is paid in crypto, Article 5(11) taxes it as a capital gain when the received crypto is later disposed of. If the remuneration is paid in fiat or another non-crypto form, the reporting path can differ.
How do residence, NHR, and IFICI affect crypto taxes?
Portugal tax residence matters because residents generally report worldwide income, while nonresidents generally report only Portugal-source income. A person can become Portuguese tax resident by spending more than 183 days in Portugal in a relevant 12-month period, or by having a dwelling available in conditions that indicate an intention to use it as a habitual residence.
That matters for crypto because a Portugal resident may need to report activity on foreign crypto exchanges, foreign platform income, and cross-border crypto transactions on Modelo 3. A nonresident's Portugal filing position depends on whether the crypto income or gain is treated as Portugal-source.
The Non-Habitual Resident (NHR) regime closed to new entrants beginning January 1, 2024, subject to transition rules. Its replacement, the IFICI regime (Incentivo Fiscal à Investigação CientÃfica e Inovação, the Tax Incentive for Scientific Research and Innovation), is narrower and does not create a general exemption for Category G crypto gains, Category E crypto yield, mining, or validation activity.

When is crypto tax-free in Portugal?
Some crypto activity is outside immediate IRS tax in Portugal, but the reason matters. A transaction can be outside tax, deferred, excluded after a holding period of 365 days or more, or routed to a different tax such as Stamp Duty.
Buying and holding crypto
Buying crypto with EUR and holding it creates records for a later calculation. You still need the acquisition date, EUR cost, fees, provider, and wallet.
Moving crypto between your own wallets
Transfers between your own wallets are non-disposals when ownership does not change. Keep records that connect both wallets to you, especially if the transfer later looks like a sale, gift, bridge, or withdrawal from an exchange.
Selling qualifying crypto held for 365 days or more
Article 10(22) excludes gains and losses from qualifying crypto-assets held for 365 days or more. That means the gain is generally excluded from IRS, and the loss is generally excluded too.
The threshold is exactly 365 days. The exclusion applies to qualifying crypto-assets, while unique NFTs, securities, and transactions affected by the anti-fragmentation rule can require a separate analysis.
Trading crypto for crypto
Crypto-to-crypto trades are generally deferred under Article 10(23). If you exchange BTC for ETH, Portugal generally does not tax the trade at that moment. The ETH takes the acquisition value of the BTC you delivered.
Gifts and inheritances
Receiving crypto as a gift or inheritance can create Stamp Duty issues, including a 10% duty on gratuitous transfers, unless a family exemption or small-gift exclusion applies.
Close family transfers to a spouse or de facto partner, descendant, or ascendant can be exempt from Stamp Duty. Small-gift exclusions can also apply, including EUR 5,000 for certain close-family transfers and EUR 500 for certain social-custom transfers. A later sale by the recipient can still require a capital gains analysis.
Which crypto transactions are taxable in Portugal?
Selling crypto for EUR
Selling qualifying crypto for EUR after holding it for fewer than 365 days is the clearest taxable Category G transaction. The gain or loss is measured against your acquisition value and deductible acquisition or disposal expenses.
Example: You buy 1 ETH for EUR 2,000 on May 1, 2026. You sell it for EUR 3,200 on October 1, 2026 and pay EUR 50 in deductible fees. Your gain is EUR 1,150. If the 28% autonomous rate applies, the tax on that gain is EUR 322.
Selling crypto for another fiat currency
Selling crypto for USD, GBP, or another fiat currency is also a disposal. Convert values to EUR using a reasonable, supportable exchange-rate record for the transaction date.
Spending crypto
Using crypto to buy goods or services is a disposal. The consideration is the item or service you received. If you spend crypto after holding it for fewer than 365 days and the asset increased in value, the gain can be taxed under Category G.
Selling or redeeming stablecoins
Stablecoins are crypto-assets unless a specific asset has a different legal character. A stablecoin sale or redemption can create a disposal. A stablecoin-for-crypto swap can fall within the crypto-for-crypto deferral if both assets are qualifying crypto-assets, but facts matter.
Paying fees in crypto
Fees paid in crypto can create a disposal of the fee token. The same fee can also support the cost or disposal calculation for the related transaction when it is a necessary and effective acquisition or disposal expense. Keep exchange fee, gas fee, and transaction hash records.
Receiving crypto as payment
If you receive crypto for work, services, habitual mining, validation, or business activity, review the income category before filing. Wages, professional income, and business income can fall outside the basic Category G investor framework.
Selling or trading NFTs
Portugal's special crypto regime excludes unique and non-fungible crypto-assets from the crypto-asset definition used for Article 10's crypto rules. Unique NFTs use a separate analysis: the 365-day exclusion, crypto-for-crypto deferral, crypto FIFO rule, and 28% autonomous crypto rate apply to qualifying crypto-assets within that special regime.
An occasional NFT sale can require general Category G analysis, while creator or business activity can fall under Category B. The result depends on what the NFT represents and how the taxpayer uses it.
Which crypto transactions are deferred or outside immediate tax?
Buying crypto
Buying crypto with fiat creates the cost basis and acquisition date that matter later. No disposal occurs at purchase.
Holding crypto
Portugal taxes disposals rather than unrealized private-investor gains. A price increase by itself does not create tax, and Portugal has no general wealth tax on crypto-assets.
Wallet transfers
Moving crypto from one wallet you own to another wallet you own remains a non-disposal when ownership does not change. If CoinTracker, an exchange, or a tax advisor cannot identify both sides of the transfer, an unmatched outflow can look like a taxable sale. Label and document transfers carefully.
Crypto-to-crypto trades
Crypto-to-crypto trades are generally deferred. The trade still matters because it changes the asset you hold and affects the acquisition-value chain for the later sale.
Crypto-paid Category E remuneration
Article 5(11) is an important Portugal-specific rule. If Category E remuneration from crypto-asset operations is paid in crypto-assets, taxation is deferred until the later disposal of the received crypto. Because no amount is taxed at receipt in that crypto-paid case, the received lot should use zero acquisition value, plus any separately allowable expenses, not receipt-day fair market value.
Portugal generally defers the tax in this crypto-paid Category E case rather than erasing it.
Gifts and inheritances before later disposal
A gift or inheritance can create Stamp Duty issues at receipt. The recipient's Category G question usually arises later, when they sell or otherwise dispose of the crypto.
How are staking, mining, airdrops, and DeFi taxed?
Staking and lending rewards
Passive staking or lending rewards can fall under Category E as income from crypto-asset operations. When those rewards are paid in crypto, Article 5(11) generally taxes them later as a capital gain when you dispose of the received crypto. The deferred reward lot should use zero acquisition value, not receipt-day fair market value, so the deferred value is taxed when the crypto is later disposed of.
Native staking lock-ups can be different from reward receipts. Locking tokens for staking is generally not a sale if you keep ownership of the same tokens. Liquid staking is more complex because you may receive a separate token, and Portugal has no direct AT rule for every protocol design.
Mining and validator activity
Mining and validation can fall under Category B when they are habitual business, professional, or commercial activity. Under the simplified regime, mining income uses a 0.95 coefficient, while other crypto operations covered by the simplified-regime rule can use a 0.15 coefficient.
Habituality is facts-based. Relevant factors include frequency and regularity, whether the taxpayer is deliberately generating income, and the economic significance of the activity compared with the taxpayer's overall profile.
Where mining is not habitual business, professional, or commercial activity, the received crypto can instead fall into the Category G capital gains framework. In that case, no tax generally arises at receipt. The later sale, conversion to fiat, spend, or other disposal is reviewed under the short-term 28% Category G rule or the 365-day exclusion, depending on the holding period and the other requirements.
Mining generally needs a Category B business or professional income review because many mining arrangements are ongoing and infrastructure-heavy. Miners and validators should review registration, business-income, expense, VAT, and social security questions with a Portuguese tax advisor.
Airdrops
Airdrops need a facts-based category review. If you receive crypto-assets through an airdrop, receipt generally does not create tax at the moment you receive the tokens. The later sale, conversion to fiat, spend, or other disposal moves into the Category G analysis, including the 28% short-term rate or the 365-day exclusion when the requirements are met.
The category still depends on why you received the airdrop. Airdrops paid as remuneration for crypto-asset operations can fall under Category E. If that income is paid in crypto-assets, the same deferred-tax logic applies: no receipt-side tax, zero acquisition value, and later Category G analysis when the tokens are disposed of. If the airdrop is paid in cash or fiat currency, current Category E tax can apply. If the airdrop is connected to services, promotion, or business activity, Category B may be relevant. Keep the claim, wallet, and project records.
Hard forks
Hard forks need careful records because Portugal's crypto guidance does not give a complete consumer rule for every fork. A chain split by itself may not be a disposal of your existing crypto, but receiving and later selling forked coins can create basis, timing, and reporting questions. Keep records showing when you gained control of the new tokens.
Wrapping and bridging
Wrapping and bridging need facts. A same-owner bridge between wallets may be closer to a transfer, while a burn-and-mint bridge or wrapper can look like a crypto-for-crypto exchange. Article 10(23) may support deferral where the consideration is another qualifying crypto-asset, but AT has not published a binding rule for every bridge or wrapper.
Bridge treatment depends on the mechanics. Match the bridge legs, keep transaction hashes, and document beneficial ownership.
Liquidity pools
Adding assets to a liquidity pool and receiving LP tokens can require a crypto-for-crypto or disposal analysis. Portugal's statutory deferral can be relevant if the consideration is another qualifying crypto-asset, but LP token mechanics vary.
The tax result can change when you add liquidity, remove liquidity, earn rewards, or sell LP tokens. Keep protocol records and have a Portuguese tax advisor review material DeFi positions before filing.
Margin, futures, and derivatives
Crypto margin, futures, and derivatives are complex, and their Portuguese tax treatment is not settled, so they need advisor review. Portugal taxes crypto-assets and financial derivatives under different rules, and the treatment of crypto futures in particular is unsettled. Work with a tax advisor if you traded perpetuals, used margin, had forced liquidations, paid margin fees in crypto, or received funding payments.
How do you calculate crypto gains and losses in Portugal?
For Category G crypto disposals, the starting formula is:
Taxable gain or loss = disposal value - acquisition value - deductible expenses
Deductible expenses can include necessary and effective costs tied to the acquisition or disposal, such as exchange commissions or gas fees, when records support the amount.
Use EUR values
Portugal tax reporting uses EUR. For every transaction, keep the EUR fair market value on the transaction date, the exchange-rate source, and the fee record.
Apply FIFO per service provider
Portugal applies FIFO to crypto-assets, and the rule applies separately by crypto-asset service provider.
Example: You bought 1 SOL on Provider A in January and 1 SOL on Provider A in June. You sell 1 SOL from Provider A in September. The January Provider A lot is disposed of first. If you also hold SOL on Provider B, the Provider B lots are tracked separately for this rule.
Check the 365-day rule
The 365-day holding period is critical:
- Disposal before 365 days: short-term Category G analysis.
- Disposal at 365 days or later: gains and losses generally excluded for qualifying crypto-assets.
Example: You buy BTC for EUR 10,000 on January 1, 2026 and sell it for EUR 14,000 on July 1, 2026. The holding period is under 365 days, so the EUR 4,000 gain is generally in the short-term Category G calculation.
If you sell the same BTC after holding it for 365 days or more, the gain is generally excluded. If it is sold at a loss after a holding period of 365 days or more, that loss is generally excluded too.
Account for crypto-to-crypto deferral
A crypto-to-crypto trade usually does not create immediate tax. It still carries your acquisition value into the new asset.
Example: You buy BTC for EUR 20,000 on January 15, 2026. On June 15, 2026, you trade that BTC for ETH when the BTC is worth EUR 25,000. Portugal generally does not tax the EUR 5,000 gain at the BTC-to-ETH swap. The ETH carries the EUR 20,000 acquisition value into the later disposal analysis.
Understand losses and aggregation
Short-term Category G crypto losses can offset short-term Category G gains in the same year. A negative balance can be carried forward for 5 years only when the taxpayer elects, or is required to use, aggregation.
Example: You have EUR 5,000 of short-term crypto gains and EUR 2,000 of short-term crypto losses in the same year. Your net positive balance is EUR 3,000 before applying the relevant rate. If instead your short-term balance is negative, you can carry the loss forward for five years, but only if you elect aggregation on the return for the loss year, and again in the year you use it. Skipping the election forfeits the carryforward. Aggregation moves your other aggregation-eligible income onto the progressive rates for that year, so it is worth electing when your marginal rate stays at or below 28%. In the top bracket it is mandatory.
How do you report crypto taxes in Portugal?
Portugal individual taxpayers report annual income through Modelo 3. Crypto reporting can involve several annexes depending on the transaction type.
| Form or annex | Common crypto use |
|---|---|
| Modelo 3 | Main individual income tax return |
| Anexo G | Taxable short-term Category G crypto gains and losses |
| Anexo G1 | Informational reporting for excluded long-term crypto gains or disposals, where applicable |
| Anexo B | Mining, validation, or professional crypto activity |
| Anexo E | Capital income, including relevant crypto remuneration |
| Anexo J | Foreign-source income or foreign platform situations |
This guide uses annex-level guidance. It does not assign exact line-by-line entries because AT form layouts, taxpayer facts, and software workflows can change.
Filing deadline
The standard filing window is April 1 to June 30 of the year after the tax year. For 2026 income, the standard filing window is April 1 to June 30, 2027.
For 2025 income filed in 2026, the standard filing deadline is June 30, 2026. When the assessment is issued on the normal timeline, payment is generally due by August 31. Late filing by a natural person can trigger a fine of EUR 150 to EUR 3,750.
Late payment can also trigger juros de mora, Portuguese late-payment interest, from the day after the legal payment deadline until payment.
Article 60 allows a limited extension to December 31 where foreign-source income creates a foreign tax credit issue and the foreign tax amount is not determined by the normal deadline. The taxpayer must notify AT within the normal filing period and identify the income and source state.
Step-by-step reporting process
- Gather your crypto transaction history for the calendar year.
- Identify disposals, crypto-to-crypto trades, wallet transfers, income, gifts, DeFi activity, and fees.
- Calculate acquisition value, disposal value, fees, and holding period in EUR.
- Apply FIFO per crypto-asset service provider.
- Separate short-term taxable disposals from long-term excluded disposals.
- Review whether income belongs on Anexo B, E, G, G1, or J.
- Decide with an advisor whether aggregation is appropriate.
- Keep the full transaction and calculation file with the return support.
When should you work with a tax advisor?
Work with a Portuguese tax advisor if your facts go beyond simple buy, hold, sell activity.
Advisor review is especially important for:
- High-volume trading.
- DeFi, liquid staking, wrapping, bridging, and liquidity pools.
- NFTs.
- Margin, futures, perpetuals, and forced liquidations.
- Mining or validation.
- Crypto income paid for work or services.
- Gifts, inheritances, or charitable donations.
- Exit from Portuguese tax residence.
- NHR transition, IFICI, or cross-border residency.
- Aggregation elections and loss carry-forwards.
What crypto tax records should you keep?
Keep enough records to prove the category, value, holding period, and reporting position for each transaction.
Keep these records at least through the ordinary 4-year assessment period. A 12-year period can apply for undeclared facts connected with tax-haven jurisdictions or undisclosed foreign accounts.
| Record | Why it matters |
|---|---|
| Transaction date and time | Supports holding period and annual reporting |
| Asset disposed or received | Identifies whether the crypto rules apply |
| EUR fair market value | Supports proceeds, currently taxed income values, and nonzero basis values where applicable |
| Provider or wallet | Supports FIFO per service provider |
| Fees | Supports acquisition and disposal expense calculations |
| Transaction hash | Supports on-chain proof |
| Transfer notes | Shows self-transfers were not sales or gifts |
| Cost basis file | Supports gain/loss calculations |
| Income category notes | Separates Category E, B, and G treatment |
| Gift or inheritance documents | Supports Stamp Duty and family-exemption analysis |
For DeFi, keep extra records. A tax advisor may need protocol names, LP token receipts, wrapped token movements, bridge legs, reward claims, and wallet ownership evidence.
Common Portugal crypto tax mistakes
Assuming Portugal never taxes crypto
Portugal can be favorable for long-term holders, but short-term disposals, income, business activity, Stamp Duty, and reporting obligations still matter.
Missing the 365-day threshold
The 365-day rule is a cliff. A sale before the threshold can be taxable. A qualifying sale at or after the threshold is generally excluded, and the loss is generally excluded too.
Treating every crypto-to-crypto trade as a taxable sale
Crypto-to-crypto trades are generally deferred, not taxed at the moment of the swap. The crypto you receive takes the acquisition value of the crypto you delivered, and the gain is reviewed at the later disposal.
Calling every NFT tax-free
Unique NFTs are excluded from the special crypto-asset regime. Each NFT sale needs its own Category G or business-income analysis.
Taxing every staking reward on receipt
Article 5(11) can defer crypto-paid Category E remuneration until the later disposal of the received crypto. The deferred lot should use zero acquisition value, not receipt-day fair market value.
Filing only Anexo G
Simple short-term sales may belong on Anexo G, but mining, validation, capital income, foreign-source income, and long-term excluded gains can require other annexes.
Ignoring provider-level FIFO
Portugal applies FIFO per crypto-asset service provider. A universal lot method can produce the wrong result if it ignores provider separation.
Assuming AT cannot receive crypto data
Current Article 124-A requires covered reporting crypto-asset service providers to report certain information to AT. Non-reporting by one platform does not remove your filing obligation.
Overclaiming losses
Long-term excluded losses generally do not reduce taxable gains. Short-term losses have same-year use, and carry-forward depends on aggregation.
How can you reduce crypto tax risk in Portugal?
Lower tax risk starts with accurate records and correct classification.
- Check holding periods before disposing of crypto.
- Separate crypto-to-crypto deferrals from fiat sales and spending.
- Keep provider-level FIFO records.
- Preserve wallet-transfer evidence.
- Review DeFi and NFT transactions before filing.
- Model aggregation only with your full income picture.
- Confirm whether any counterparty is in a favorable-tax jurisdiction.
- Keep advisor-ready transaction notes.

Portugal crypto tax FAQ
Is crypto taxed in Portugal in 2026?
Yes. Portugal taxes crypto through Category G, Category E, Category B, and Stamp Duty depending on the activity. Short-term capital gains from qualifying crypto disposals are generally taxed at 28%, while qualifying gains and losses from crypto held for 365 days or more are generally excluded.
Is Portugal tax-free for crypto?
No. Portugal can be favorable for long-term holders, but short-term sales, spending, mining, validation, certain rewards, gifts, inheritances, NFTs, DeFi, and reporting obligations can still create tax or filing consequences.
What is the 365-day crypto tax rule in Portugal?
Article 10(22) generally excludes gains and losses from qualifying crypto-assets held for 365 days or more. If the crypto is sold before 365 days, a Category G gain or loss analysis generally applies.
Are crypto-to-crypto trades taxed in Portugal?
Crypto-to-crypto trades are generally deferred under Article 10(23). If the consideration you receive is another qualifying crypto-asset, Portugal generally does not tax the swap at that moment. The received crypto takes the acquisition value of the crypto you delivered.
Does swapping crypto reset my holding period in Portugal?
Crypto-to-crypto swaps are generally not taxed at the moment of the trade, and the crypto you receive takes the acquisition value of the crypto you delivered. How the 365-day holding period is counted across a swap is not settled by published AT guidance, so check with a Portuguese tax advisor before relying on a swap to reach the long-term exclusion.
What tax rate applies to crypto gains in Portugal?
Short-term taxable Category G crypto gains are generally taxed at the 28% autonomous rate unless the taxpayer elects aggregation. Aggregation can move the gain into progressive IRS rates and can affect loss carry-forward eligibility.
How are staking rewards taxed in Portugal?
Passive crypto rewards can fall under Category E. If the reward is paid in crypto, Article 5(11) generally taxes it later as a capital gain when the received crypto is disposed of. The deferred reward lot should use zero acquisition value. Liquid staking and some DeFi reward structures need fact-specific review.
How are airdrops taxed in Portugal?
Crypto-asset airdrops generally are not taxed at receipt. The later sale, conversion to fiat, spend, or other disposal can be taxed under Category G at 28% unless the 365-day exclusion applies.

How is crypto mining taxed in Portugal?
Mining usually needs a Category B business or professional income review because many mining arrangements are habitual and infrastructure-heavy. Under the simplified regime, mining income uses a 0.95 coefficient. If mining is not habitual business, professional, or commercial activity, the received crypto can instead be reviewed under Category G, with no tax at receipt and later disposal analysis.
Are NFTs taxed in Portugal?
Yes. NFT sales can be taxable in Portugal. Unique and non-fungible crypto-assets are excluded from the special crypto-asset regime in Article 10, so the crypto 365-day exclusion, crypto-for-crypto deferral, provider-level FIFO rule, and 28% autonomous crypto rate apply only when the asset is a qualifying crypto-asset. An occasional NFT sale can require general Category G analysis, while creator or business activity can fall under Category B.
How do I report crypto on Modelo 3 (Form 3)?

Do I use Anexo G (Annex G) or Anexo G1 (Annex G1) for crypto?

Are crypto gifts or inheritances taxed in Portugal?

A later sale by the recipient can still require a capital gains analysis.
Does IFICI or old NHR exempt crypto gains?

Can AT see crypto held on foreign exchanges?
AT visibility is increasing through CIRS Article 124-A and reporting by covered crypto-asset service providers. AT may not see every self-custody or DeFi transaction, but lack of direct platform reporting does not remove a taxpayer's reporting obligations.
Can CoinTracker help with Portugal crypto taxes?
