Portugal Capital Gains Tax on Property: 2026 Guide

Quick Answer: Non-residents pay 28% on the capital gain when selling Portuguese property. Residents include 50% of the gain in their IRS return at marginal rates. Primary-home reinvestment within 36 months can defer tax for residents.

Capital Gains Tax Rates — Residents vs Non-Residents

Capital gains tax on Portuguese property depends entirely on your tax residency status. Non-residents face a straightforward flat rate, while residents use progressive inclusion.

Non-Resident Rate: 28% Flat

Non-residents selling Portuguese property pay 28% tax on the capital gain. This rate applies regardless of:

How long you owned the property
Property value or gain amount
Whether it was rental investment or holiday home
Your home country tax obligations

Resident Rate: 50% Inclusion

Portuguese tax residents include 50% of the capital gain in their annual IRS (income tax) return. The included amount gets taxed at your marginal rate:

Annual Income (€)	Marginal IRS Rate	Effective CGT Rate
Under 7,703	14.5%	7.25%
7,703 - 11,623	23%	11.5%
11,623 - 16,472	28.5%	14.25%
16,472 - 21,321	35%	17.5%
21,321 - 27,146	37%	18.5%
27,146 - 39,791	45%	22.5%
Over 39,791	48%	24%

Example: If you’re a Portuguese resident earning €25,000 annually and sell investment property with €30,000 gain:

Taxable amount: €30,000 × 50% = €15,000
Tax rate: 37% (your marginal rate)
Capital gains tax: €15,000 × 37% = €5,550

How to Calculate Capital Gains

Capital gains = Sale Price - Adjusted Cost Basis - Selling Costs

Determining Your Cost Basis

Your cost basis includes:

Original Purchase Costs:

Property purchase price
IMT (property transfer tax) paid at purchase
Notary and registration fees
Legal fees and surveys
Real estate agent commission (buyer’s side)

Improvement Costs (with receipts):

Renovations and construction work
Structural improvements
New installations (pool, garage, central heating)
Kitchen and bathroom upgrades
Not included: Regular maintenance, repairs, or furnishing

Inflation Adjustments for Long Holdings

Portugal allows inflation adjustments on qualifying costs:

Purchase price and improvement costs older than 5 years
Uses official inflation coefficients published annually
Can significantly reduce taxable gains on long-term holdings

Example: Property bought in 2015 for €200,000 gets inflated to approximately €235,000 in 2026 calculations.

Deductible Selling Costs

When selling, deduct these costs from your gain:

Real estate agent commission (typically 5-6%)
Legal fees for sale completion
Notary and registration costs
Property certificates and inspections
Marketing costs with receipts

Primary Residence Exemptions

The Main Exemption: Reinvestment Rule

If you sell your primary residence and reinvest proceeds in another Portuguese property, you can defer capital gains tax entirely:

Requirements:

Property must be your primary residence for 2+ years
Purchase replacement property in Portugal within 36 months
Invest equal or greater amount than the sale proceeds
Replacement property becomes your new primary residence

How it works: The tax isn’t forgiven—it’s deferred. Your new property’s cost basis reduces by the deferred gain amount.

Age-Based Exemptions

Residents over 65 get partial exemptions:

Up to €50,000 of gain is tax-free if you’re over 65
Applies to primary residence sales only
Combines with reinvestment exemption for maximum benefit

Worked Example: Primary Residence Sale

Scenario: Portuguese resident couple, both 67, selling primary home after 8 years:

Sale price: €450,000
Original cost (inflation-adjusted): €280,000
Improvement costs: €35,000
Selling costs: €25,000
Raw gain: €450,000 - €280,000 - €35,000 - €25,000 = €110,000

Tax calculation:

Age exemption: €50,000 × 2 spouses = €100,000 exempt
Remaining gain: €110,000 - €100,000 = €10,000
Taxable (50% inclusion): €10,000 × 50% = €5,000
Tax due: €5,000 × 37% = €1,850

If reinvesting: €0 tax due immediately, but cost basis of new property reduces by €110,000.

Real Estate Investment Scenarios

Buy-to-Let Property Sale

Non-resident investor example:

Purchase price (2020): €180,000
Purchase costs: €12,000 (IMT + fees)
Renovations: €25,000
Sale price (2026): €280,000
Sale costs: €16,000

Calculation:

Total cost basis: €180,000 + €12,000 + €25,000 = €217,000
Net proceeds: €280,000 - €16,000 = €264,000
Capital gain: €264,000 - €217,000 = €47,000
Tax due: €47,000 × 28% = €13,160

Holiday Home Disposal

Portuguese resident selling Algarve apartment:

Owned for 12 years as holiday home
Original cost: €120,000 (inflated to €145,000)
Sale price: €220,000
Selling costs: €13,000
Capital gain: €220,000 - €145,000 - €13,000 = €62,000

Tax calculation:

Taxable amount: €62,000 × 50% = €31,000
Assuming 35% marginal rate: €31,000 × 35% = €10,850

Multiple Property Portfolios

Offsetting Gains and Losses

You can offset capital losses against gains in the same tax year:

Portfolio example:

Property A gain: €40,000
Property B loss: €15,000
Property C gain: €25,000
Net gain: €40,000 + €25,000 - €15,000 = €50,000

For non-residents: Tax on €50,000 at 28% = €14,000 For residents: Include €25,000 (50%) in IRS return

Loss Carryforward Rules

Unused capital losses can carry forward for 5 years:

Year 1: €20,000 loss, €8,000 gain = €12,000 loss carried forward
Year 2: €30,000 gain - €12,000 carried loss = €18,000 taxable gain
Losses must be used chronologically (oldest first)

International Tax Considerations

Double Taxation Treaties

Portugal has tax treaties with most countries to prevent double taxation:

Common treaty provisions:

Capital gains typically taxable in country where property located (Portugal)
Your home country may give credit for Portuguese tax paid
Some treaties have different rules for primary residences

Key treaty countries:

UK: Portugal can tax property gains; UK gives credit
USA: Same property-source taxation rule applies
Germany: Complex rules depending on holding period
France: Generally Portugal-source taxation accepted

Tax Planning for Nomads

Establishing Portuguese tax residency can reduce capital gains tax:

Qualify for resident rates (typically lower effective rate)
Access to primary residence exemptions
Ability to use progressive system and deductions

Requirements for Portuguese tax residency:

Spend over 183 days per year in Portugal, OR
Have a permanent home in Portugal on December 31st

NHR Program Considerations

Non-Habitual Resident (NHR) status doesn’t affect Portuguese capital gains tax:

Property gains still subject to standard resident rates
NHR benefits apply to foreign income, not Portuguese property
Primary residence exemptions still available

Filing Requirements and Deadlines

Non-Resident Obligations

Primary residence reinvestment serves similar purpose
Corporate restructuring may allow tax deferral
EU directive provisions for cross-border exchanges

Common Mistakes to Avoid

Record-Keeping Failures

Keep detailed records of:

Quick Reference Summary

Taxpayer Type	Rate	Filing Deadline	Key Exemptions
Non-Resident	28% flat	31 days after sale	None available
Resident	7.25%-24% effective	July 31st (annual)	Primary residence reinvestment

Key planning opportunities: Residency optimization, timing of sales, loss harvesting, reinvestment deferrals

Portugal’s capital gains tax system rewards long-term primary residence ownership while maintaining competitive rates for international investors. Understanding your residency status and available exemptions can save thousands in unnecessary taxes.

Worked exit example: non-resident investor (€400k purchase, 5-year hold)

Purchase in 2021 at €400,000 plus €30,000 IMT and €5,000 closing costs (cost basis €435,000). Sale in 2026 at €510,000 with €15,000 agent and legal fees. Gross gain: €60,000. Non-resident CGT at 28%: €16,800 net tax. Effective tax on gross appreciation: about 14% of the €110,513 price rise because only net gain is taxed after documented costs.

Line item	Amount
Sale price	€510,000
Minus cost basis (purchase + IMT + fees)	€435,000
Minus selling costs	€15,000
Taxable gain	€60,000
CGT at 28% (non-resident)	€16,800
Net proceeds after CGT	€478,200

Residents with the same numbers would include €30,000 (50% of gain) in IRS. At a 35% marginal rate, tax is €10,500, lower than the flat non-resident charge in this scenario, but high earners can pay more.

Portuguese Estate field note

We stress-test exit models with clients before CPCV: if your hold period is under three years, CGT and selling costs can erase most of the gross yield you projected from Airbnb or long-term rent. Pair this page with due diligence and AL licensing if STR income is part of the thesis.

Plan exit before you buy: cost of buying property, IMT reform 2026, rental yield guide, investment pillar, buy as foreigner.

How to calculate taxable gain (step-by-step)

Use this sequence when your lawyer sends the pre-sale estimate:

Start with the escritura sale price (not the agency marketing ask).
Subtract documented cost basis: purchase price, IMT paid at acquisition, stamp duty, notary and registration at purchase, and capital improvements with VAT invoices.
Subtract selling costs: agency commission, lawyer, energy certificate if required for sale.
Apply 28% to the net gain if you are non-resident; residents include 50% of the net gain in IRS.

Example: bought €380,000 in 2022, spent €45,000 on documented kitchen and HVAC, sell €520,000 in 2027 with €18,000 selling costs. Net gain ≈ €77,000. Non-resident CGT ≈ €21,560. Effective rate on total price appreciation is lower than 28% because basis includes fees and works.

Interaction with annual holding taxes

Capital gains tax is separate from IMI and AIMI paid while you own the asset. Non-resident rental income is often withheld at 28% as well, so a single year can involve three different Portuguese tax touchpoints: IMI in April, rent withholding monthly, and CGT on exit. Budget all three in your investment pillar model.

Decision framework for investors

Before you buy, model exit tax in three scenarios: 5-year hold with 5% appreciation, 24-month flip, and residency change from non-resident to resident mid-hold. Non-resident 28% flat often beats resident marginal rates only for lower IRS brackets.

Risks and red flags on capital gains

Selling without a Modelo 3 or non-resident return within 31 days triggers penalties and interest.
Undocumented renovation costs cannot reduce the gain; keep invoices with NIF and property address.
Primary-home reinvestment exemption requires proof of habitual residence, not a holiday home.
US and UK citizens may owe home-country tax after Portuguese CGT; treaty relief varies.
Inheritance step-up in basis helps heirs but stamp duty and registration still apply on transfer.

Buyer scenarios: exit tax by profile

Profile	Typical CGT outcome	Planning note
US non-resident investor	28% on net gain + possible US reporting	Model PFIC and foreign tax credit with CPA
Portuguese resident retiree	50% inclusion, often 14.5–35% effective	Primary home reinvestment if downsizing
Brazilian diaspora resident	Resident rules after 183 days	Align with IMT refund timeline
French Algarve second home	28% non-resident if FR tax resident	Compare with stamp duty on next purchase

Pros and cons summary

Pros	Cons
Clear 28% non-resident rate	No holding-period discount for non-residents
Deductible acquisition and improvement costs	Strict documentation required
Resident reinvestment deferral on primary home	Holiday lets do not qualify as primary
Loss carry-forward for residents	Cross-border double taxation risk

Exit tax scenarios at three purchase price points

The table below models a non-resident buyer at three price points using a six-year hold and 4% annual appreciation. Purchase costs include IMT at 7.5% plus notary, registration, and legal at 2%. Selling costs at 6%.

Purchase price	Sale price (6 yr)	Cost basis	Selling costs	Taxable gain	CGT at 28%	Net after CGT
€350,000	€442,000	€378,500	€26,520	€37,000	€10,360	€405,120
€500,000	€631,500	€540,000	€37,890	€53,610	€15,011	€578,599
€600,000	€757,800	€648,000	€45,468	€64,332	€18,013	€694,319

CGT applies only to the net gain, not the sale price. A €600,000 buyer who appreciates to €757,800 pays an effective tax of under 7% on the gross price increase once allowable costs are deducted.

Portuguese resident comparison at €600,000: include €32,166 (50% of the gain) in IRS at 37% marginal rate equals €11,901. A 48% bracket resident would pay €15,440, which exceeds the flat non-resident rate. Non-resident status becomes advantageous for higher earners even at the 28% flat rate.

Worked scenario A: Cascais apartment at €350,000

Maria, a UK tax resident, buys a Cascais one-bed in 2020 for €350,000, paying IMT of €14,860 and €4,300 in notary and legal fees. She spends €12,000 on kitchen and bathroom works in 2021 and keeps all VAT invoices linked to her NIF and the property address. She sells in 2026 for €434,000 with agency and legal totalling €23,870.

Cost basis: €350,000 + €14,860 + €4,300 + €12,000 = €381,160. Net proceeds: €410,130. Taxable gain: €28,970. CGT: €8,112.

Without the documented renovation the gain would have been €40,970 and CGT €11,472. Keeping invoices saved €3,360 in tax. For the full acquisition cost stack that becomes cost basis, see stamp duty and cost of buying.

Worked scenario B: Porto penthouse at €500,000

Carlos and Ana, Portuguese tax residents, buy a Porto penthouse as their primary residence in 2022 for €500,000 and sell in 2026 for €610,000. Selling costs total €31,000.

Taxable gain: €48,000. Taxable amount after 50% inclusion: €24,000. At 37% marginal rate the tax is €8,880.

They reinvest the full net proceeds in a suburban family home. Reinvestment exemption applies: no CGT is due today. The new property’s cost basis is reduced by €48,000, so future gains on that asset start from a lower base, but the couple pays nothing at this exit.

Worked scenario C: Algarve villa at €600,000

David, a US passport holder with no Portuguese tax residency, buys an Algarve villa for €600,000 in 2021, completes €18,000 in pool and terrace works with invoices, and sells in 2026 for €710,000 with €38,000 in selling costs.

Cost basis: €600,000 + €38,600 (IMT and fees) + €18,000 = €656,600. Net proceeds: €672,000. Taxable gain: €15,400. CGT at 28%: €4,312.

US citizens must report the gain on Form 1040 Schedule D. Portuguese CGT paid generally provides a foreign tax credit, but dollar-euro movement can create a modest additional US liability. Model the currency scenario with your CPA before agreeing a sale price with the buyer.

Wave 3 process: how DL 97/2026 affects CGT planning

DL 97/2026 and the associated AT circulars update three practical aspects of the exit landscape. First, the flat 7.5% non-resident IMT replaces the earlier progressive schedule for most urban purchases, changing the cost basis that flows into your CGT calculation (see IMT reform hub for full rate comparison). Second, the AT portal now accepts non-resident CGT filings electronically rather than requiring an in-person submission within 31 days, materially reducing compliance risk for sellers living abroad. Third, official guidance now explicitly extends the primary-home reinvestment exemption to EU-resident retirees downsizing within Portugal, resolving a long-standing ambiguity for that buyer group.

For total acquisition cost modelling, pair this guide with stamp duty before you run exit projections. For pre-purchase legal checks that affect which costs qualify as deductible cost basis, see due diligence. If you plan to generate rental income before eventual sale, the moderate-rent incentives guide explains how structured leases interact with holding-cost offset and the overall exit model.

Investors building a full acquisition-to-exit model should treat IMT and stamp duty at purchase, holding taxes (IMI and AIMI) annually, and CGT at exit as three separate line items before arriving at a net IRR figure.

Tax planning checklist before you sell

Before you agree a sale price, verify these eight points with your Portuguese lawyer and tax adviser:

Confirm cost basis documentation: purchase deed, all acquisition receipts, capital improvement invoices with NIF and property address, and inflation-adjusted figures for costs older than five years.
Check your tax residency status. One wrong assumption on resident versus non-resident changes the tax calculation entirely.
Review loss carry-forward positions from other Portuguese properties sold in the past five years.
Confirm the primary-home qualification: two or more years of habitual residence with supporting utility bills, municipal registration, and AT records.
Calculate the reinvestment window. If you plan to claim the exemption, you have 36 months from the sale date to complete purchase of the replacement property.
Obtain a double-taxation treaty opinion from your home-country tax adviser to confirm foreign credit availability.
Get three independent valuations before setting the asking price: underpricing creates negotiating room but has no CGT benefit and reduces net proceeds directly.
Verify the non-resident filing deadline. It is 31 days from deed date, not completion of funds transfer. Missing it by one day triggers a 20% penalty on the tax due.

Frequently Asked Questions

What is the capital gains tax rate for non-residents selling Portuguese property?

Non-residents pay a flat 28% tax rate on the capital gain from Portuguese property sales. This rate applies regardless of how long you owned the property.

How is capital gains tax calculated for Portuguese residents?

Portuguese residents include 50% of the capital gain in their annual IRS income tax return, taxed at their marginal rate (14.5% to 48%). The effective rate is typically 7.25% to 24%.

Can I reinvest capital gains to avoid tax in Portugal?

Yes, if you sell your primary residence and reinvest the proceeds in another Portuguese property within 36 months, you can defer capital gains tax through the reinvestment exemption.

What expenses can I deduct from capital gains in Portugal?

You can deduct original purchase price, IMT tax, notary fees, registration costs, improvement costs with receipts, and selling costs including real estate agent fees.

How long do I need to hold Portuguese property to get tax benefits?

There's no minimum holding period for preferential rates. However, improvements older than 5 years get inflation adjustments, and primary home exemptions require 2+ years of residence.

Do I pay capital gains tax if I inherit Portuguese property?

No capital gains tax on inheritance. Your cost basis becomes the property's market value at inheritance date, so future sales calculate gains from that higher baseline.

Can I offset capital gains with losses from other Portuguese properties?

Yes, capital losses from Portuguese property can offset capital gains in the same tax year. Unused losses can carry forward for up to 5 years.

When must I pay capital gains tax after selling Portuguese property?

Non-residents must file and pay within 31 days of the sale completion. Residents include gains in their annual IRS return, due by July 31st of the following year.

What is the exit tax on a €500,000 Portuguese property after a six-year hold?

A non-resident buying at €500,000 and selling six years later at roughly €631,500 faces approximate CGT of around €15,000 on a taxable gain of €53,610, after deducting purchase fees, documented improvements, and selling costs. The 28% flat rate applies to the net gain only, not the full sale price, keeping the effective tax under 8% of the total price appreciation.

Does DL 97/2026 change the capital gains tax rate for non-residents?

DL 97/2026 primarily changes the IMT transfer tax rate and administrative procedures, not CGT. Capital gains tax remains 28% flat for non-residents. Wave 3 reforms allow electronic non-resident CGT filings and clarify the primary-home reinvestment exemption for EU-resident retirees downsizing to smaller Portuguese properties.
