Portugal - Deadline for paying AIMI has started and ends at the end of September

The deadline for settling the Additional Municipal Property Tax (AIMI) began in September and runs until the end of the month. This tax applies only to properties with a high Taxable Property Value (VPT), with differentiated rates depending on the VPT amount and the taxpayer’s status.

The AIMI — Additional Municipal Property Tax — can be paid from 1 September 2025 and the deadline is the end of September.

It applies only to owners whose Taxable Property Value (VPT) exceeds €600,000. The Portuguese Tax Authority calculates it in June based on the VPT recorded as of 1 January of the fiscal year.

Rates for individuals vary by VPT:

• 0.7 % for VPT from €600,000 to €1,000,000,

• 1 % for VPT above €1,000,000 and up to €2,000,000,

• 1.5 % for VPT above €2,000,000.

For corporations, a flat rate of 0.4 % applies to the entire VPT of residential urban buildings and land for construction.

Properties held by entities in tax havens face a higher rate of 7.5 %.

In 2024, the State collected €154.52 million in AIMI, covering 570,961 properties owned by 93,516 taxpayers. Of this, €121.02 million came from corporations and €33.5 million from individuals.

Conclusion

AIMI represents a significant fiscal burden for owners of high-value properties. It is essential to meet the deadline by the end of September to avoid penalties such as interest or fines. Given the financial impact, property owners should proactively verify applicable rates and use the correct references to make timely payments.
