Portugal Tax Guide for Property Investors 2026

By Taxpert Editorial · Last reviewed: 26 April 2026

Portugal's property market has attracted substantial international investment. Understanding the full tax cost — from purchase (IMT, IS) through rental income (Cat. F) to eventual sale (Cat. G) — is essential for accurate return calculations. This guide covers each stage.

Purchase taxes

IMT — Imposto Municipal sobre Transmissões

IMT is paid by the buyer on every property purchase. Rates depend on property type and purchase price:

• Primary residence: 0% up to €97,064; progressive up to 8% on amounts above €1,050,400
• Secondary / investment: Flat 6% (urban) or 5% (rural)
• Commercial: 6.5%
• Properties via offshore entities: 10%

IS — Imposto do Selo

Stamp duty (IS) of 0.8% applies to all property purchases. On a €400,000 property, this is €3,200.

Annual property tax: IMI

IMI is charged annually on the fiscal value (VPT — valor patrimonial tributário) of the property. The VPT is usually lower than market value, especially for older properties.

• Urban: 0.3%–0.45% of VPT (set by each municipality)
• Rural: 0.8% of VPT
• Primary residence: significant exemption for owner-occupiers in the first years

IMI is deductible as an operating expense for landlords computing Cat. F rental income.

Rental income: Category F

Rental income from Portuguese property is Category F. Default rate: 28% flat (taxa autónoma). Significant reductions for long-term leases:

• Lease under 5 years: 28%
• 5–10 years: 26%
• 10–20 years: 15%
• 20+ years: 10%
• Moderate rents program: 10%

Deductible expenses for landlords: IMI, condominium fees, insurance, maintenance costs (subject to documentation), and depreciation on furniture for furnished rentals. Mortgage interest is not deductible for residential buy-to-let (commercial property may allow partial deduction under organized accounting).

Short-term rental (Alojamento Local)

Short-term rental (Airbnb-style) via an Alojamento Local (AL) license is classified as Cat. B self-employment income, not Cat. F. Under the simplified regime, the coefficient for apartment AL is 0.55 — meaning 55% of gross revenue is taxable. AL income may qualify for IFICI if the taxpayer has an AL business structure, but this is complex — consult a TOC.

Capital gains: Category G

When you sell a property, the gain is Category G. For Portuguese tax residents:

• 50% inclusion rule: Only 50% of the net gain is taxable for residents
• Rate: 28% flat on the taxable 50%, or aggregation with progressive brackets
• Primary residence exemption: If you reinvest the full sale proceeds into another primary residence within 24 months (or 36 months pre-purchase), the gain is fully exempt
• Inflation adjustment: AT applies official coefficients to the acquisition cost for properties held longer — reducing the taxable gain

For non-residents: 28% on 100% of the gain (EU/EEA residents can elect aggregation and apply the 50% inclusion).

Capital gains calculation example

Purchased 2015 for €250,000 (plus €15,000 purchase costs). Sold 2026 for €420,000 (minus €8,000 agent fees). Assume AT inflation coefficient of 1.08 for 2015.

• Adjusted acquisition cost: (€250,000 + €15,000) × 1.08 = €286,200
• Net proceeds: €420,000 − €8,000 = €412,000
• Net gain: €412,000 − €286,200 = €125,800
• Taxable 50%: €62,900
• IRS at 28%: €17,612

Portfolio structure considerations

Property held through a Portuguese company (sociedade) may face different IMI rates (0.4%), IRC (21% corporate tax) on rental income and gains, and IMT at corporate rates. For one or two properties, individual ownership is usually simpler. For larger portfolios, a structure analysis with a TOC and tax lawyer is worthwhile.
