IMI Rates in 2025: What to Expect

In Portugal, IMI rates are applied by each municipality within a set range:

  • Urban Properties: 0.3% to 0.45% of the property’s taxable value (VPT – Valor Patrimonial Tributário).
  • Rural Properties: Fixed at 0.8%.
  • Properties Owned by Entities in Tax Havens: 7.5%.

Most municipalities, including Lisbon, Faro, Lagos, Leiria, Oeiras, Sintra, and Viseu, maintain the lowest IMI rate of 0.3%, according to the Portal das Finanças. Meanwhile, Nazaré, Mafra, and Cartaxo apply the maximum rate of 0.45%.

To check the IMI rate for a specific municipality, visit the Portal das Finanças for official data.

How is IMI Calculated?

IMI is based on the VPT of the property, a value determined by the Portuguese Tax Authority using factors such as:

  • Property size
  • Year of construction
  • Location
  • Market value of similar properties
  • Overall condition

For example, if a property in Lisbon has a VPT of 200.000€ and the local IMI rate is 0.3%, the annual IMI will be 600€. However, keep in mind that the VPT can be re-evaluated annually.

When Should IMI Be Paid?

The IMI payment schedule depends on the amount due:

  • Up to 100€: Full payment in May.
  • Between 100€ and 500€: Two payments, in May and November.
  • Above 500€: Three payments, in May, August, and November.

The Tax Authority (Finanças) issues IMI payment notices in April, providing payment references and deadlines. You can choose to pay the IMI in full or in installments. Late payments may result in interest charges, and persistent delays could lead to tax enforcement action.

How Does IMI Impact Your Real Estate Investment in Portugal?

IMI is a key factor to consider when planning long-term property investments in Portugal. It directly impacts rental yields and overall return on investment (ROI). Non-resident buyers should factor IMI into their property budget and explore potential exemptions and incentives.

Some attractive tax benefits for investors include Portugal’s Golden Visa and the Non-Habitual Resident (NHR) regime, both of which can provide significant financial advantages. To navigate these tax complexities and optimize your investment, consulting with a specialized real estate agency like Vasco Invest is highly recommended.
