Once effective, the reform will reduce the autonomous IRS rate on rental income from 25% to 10% for landlords charging rents up to €2,300 per month. The reduction applies to both new and existing contracts, for income earned until 31 December 2029.

Who can benefit?

The 10% rate applies to residential leases that fall within the definition of “moderate rent”, a concept aimed at covering mainstream housing for middle-income families.

Under the proposal, moderate rent corresponds to a monthly value not exceeding 2.5 times the national minimum wage projected for 2026, currently around €2,300.

Example: a landlord receiving €1,500/month would pay around €1,800/year in IRS, instead of €4,500, representing a 60% reduction.

Both existing and new leases may benefit, provided they meet the eligibility thresholds.

Landlords offering rents 20% below the municipal median may access a full IRS exemption under the new Simplified Affordable Rental Regime, which replaces the former rental support programme.

Key requirements include:

  • Minimum 3-year contracts for permanent residence;
  • Compliance with rent caps at 80% of the local median price.

Impact on companies

Corporate taxpayers (IRC) also benefit: eligible rental income will be taxed on only 50% of its value, reducing the effective rate.

The measure aims to promote more accessible rental options by reducing risk for landlords and increasing net profitability. Whether this will widen supply in a constrained housing market remains to be seen.
