Portugal remains one of Europe's most popular markets for foreign buyers — but the spread between gross and net yield is wider than most newcomers expect. Four taxes do most of the work. The figures below are the same baseline assumptions HypeCity's tax engine uses; treat them as modeling defaults, not gospel, and verify the current schedule with a Portuguese notary before signing.

1. IMT — the transfer tax at purchase

IMT (Imposto Municipal sobre as Transmissões) is progressive and lands at roughly ~6% on a typical investor-grade purchase, with rates varying by price band, property type and whether it is a primary residence. On top of IMT comes stamp duty and notary/registration costs — budget the full acquisition stack before comparing Portugal to markets with thinner closing costs.

2. IMI — the annual holding tax

IMI (the municipal property tax) is comparatively gentle — modeled at ~0.4% of taxable value per year, set municipality by municipality. It rarely kills a deal, but on thin-yield prime Lisbon it is not nothing.

3. Rental income — 28% flat

Non-resident rental income is taxed at a flat 28% (residents can opt into progressive scales). A property grossing €1,700/month loses ~€476 of it to tax before a single expense — model net-of-tax yield, not advertised yield. This single line is why HypeCity scores every Portuguese neighborhood net of per-country tax.

4. Capital gains — 28% at exit

Non-resident capital gains are modeled at 28%. Holding-period reliefs, reinvestment exemptions for residents, and the post-NHR regime landscape change frequently — the old NHR program closed to new applicants, and its successor regime is narrower. This is the section where a Portuguese tax adviser pays for themselves several times over.

Worked example. €480,000 Lisbon T2 at €1,700/month gross: ~€28,800 IMT at purchase, ~€1,900/year IMI, rent taxed to ~€1,224/month net — a 4.25% gross yield becomes roughly 2.8–3.0% net of tax before financing. Run your own numbers in the Tax Exposure Letter or the 10-year Cash Flow tool.

Where in Portugal? Let the data argue

HypeCity scores Portuguese neighborhoods from Alfama to Foz do Douro inside a catalog of 24,051 worldwide — yield, momentum, and risk, already adjusted for the tax layer above. Open the Leaderboard and filter to Portugal, or ask Antonia for the cross-border view from your home country (treaty relief on that 28% withholding depends on where you are tax-resident).
