IRS Rendas 2026: Anexo F, Rental Income and the 10% Rate

Anexo F is the annex to Portugal's annual IRS return (the Modelo 3 declaration) where Category F income — *rendimentos prediais*, i.e. rents — is declared. If you received residential rent in 2026 as an individual, you file Anexo F with your Modelo 3 the following spring, identifying the property, the lease, the amounts received and the documented expenses you deduct.

It applies to individual landlords; company-owned properties follow corporate tax rules instead. This guide covers landlords who hold property personally — the vast majority of Portugal's small landlords.

The standard rate: 25%. Under Art. 72º CIRS, residential rental income is taxed autonomously at a flat 25% — you pay 25% of the taxable rental result, regardless of your other income.

The new 10% rate — Decreto-Lei n.º 97/2026, de 20 de maio. Approved under the authorization of Lei n.º 9-A/2026, de 6 de março, this 2026 regime cuts the rate to 10% when all of the following hold:

The reduced rate applies to income received from 1 January 2026 until the end of 2029, and covers both new and in-progress contracts — an existing 3+ year lease at a moderate rent qualifies for its 2026 income onward.

The alternative: aggregation (englobamento). Instead of the autonomous rate, you may opt to aggregate rents with your other income and pay your general progressive IRS rates. This tends to benefit landlords whose total income falls in a lower bracket — run the numbers before opting in.

A worked example. Rent of €1,500 per month is €18,000 per year.

Note that €1,500 sits comfortably under the €2,300 ceiling, so a 3+ year contract for the tenant's permanent home at this rent qualifies, provided the Modelo 2 communication and the Anexo F declaration are in order.

Expenses reduce the taxable base. Documented expenses — maintenance and repairs, condominium charges, IMI — can be deducted from rental income before the rate is applied. Keep the invoices: undocumented expenses are not deductible.

Deadlines. Anexo F is filed with the Modelo 3 during the annual IRS filing window (April to June). Declare the amounts actually received in the year — if you updated the rent during 2026 using the INE coefficient (1,0224, per Aviso n.º 23174/2025/2), the annex must reflect the real, updated amounts.

CompliantLease keeps the paper trail Anexo F depends on: every rent you record in the ledger is tracked, and a courtesy receipt PDF is generated and sent automatically — so received amounts, receipts and the contract always tell the same story. Tax-season summaries that assemble the year's figures for your accountant are planned for launch. The official receipts and the tax filing itself remain on the Portal das Finanças.
