Key points

  • Article 45.º-C of the Tax Benefits Statute (EBF), part of the 2026 measures, taxes rental income (category F) from moderate-rent housing contracts at an autonomous 10% — applicable until 31 December 2029.
  • Rent is "moderate" under a cap of 2.5 times the guaranteed monthly minimum wage — for 2026, rent in the region of EUR 2,300 per month.
  • For category B income under organised accounting, taxation is limited to 50% of the income received.
  • The regime interlocks with non-resident IMT: committing the property to moderate letting (36 months within the first five years) is one of the two refund routes for the 7.5% surcharge — the two texts are read together.
  • The benefit has an end date; an investment plan carrying it beyond 2029 without a review clause rests on an assumption, not a statute.

A calibrated incentive, not a general regime

The Portuguese legislator did not lighten rental taxation: it bought a behaviour — capped, long, declared rents. The 10% rewards allocation, not ownership. Outside the template (rent above cap, tourist furnished, short lease), ordinary law resumes, full rates included.

The investor's arithmetic

At a cap of roughly EUR 2,300 monthly, the regime bounds gross income but secures the net: a final 10% against materially higher general-regime category F rates. On a mid-segment asset — precisely where market rent flirts with the cap — the net gap can invert the comparison with a dearer but heavier-taxed letting. It is a case-by-case computation; it is rarely made.

The interplay with the 7.5% IMT

For the non-resident hit by the flat acquisition rate, moderate letting is more than an income regime: it is the restitution route for the IMT surcharge (36 months of letting, continuous or not, within the first five years). The same contract then produces two effects — income taxed at 10%, IMT differential recovered. Few regimes offer that double reading; this one expires at end-2029.
