Last IMI instalment of the year is due by 30 November. It must be paid by those whose annual property tax is over €100
By Monday, 30 November, owners of flats, houses, garages and plots of land must pay this year's last instalment of IMI, the annual property tax (gov.pt). The tax is based on the property you owned on 31 December last year and is paid in instalments, the number of which depends on the amount.
If your IMI for the year is no more than €100, it was due in full by 31 May, and there is nothing to pay in November. If it is between €100 and €500, there are two instalments: by 31 May and by 30 November. If it is over €500, there are three: by 31 May, 31 August and 30 November. Anyone who paid the whole amount in one go in May has nothing to pay in November either.
The payment details (referência multibanco) were in the notice the tax office sent in May. They can also be found in your Portal das Finanças account, in the IMI section, separately for each instalment. You can pay at a cash machine, through online banking or at a tax office.
If you miss the 30 November deadline, late-payment interest will start to build up, and the tax office may also fine you.
The IMI rate is set by the municipality: from 0.3% to 0.45% of the rateable value (VPT) for flats and houses, and 0.8% for rural plots. If a house has been empty for more than a year or is derelict, and is in an area with a housing shortage, the rate is ten times higher and rises by a further 20% each year (Notícias ao Minuto).
The consumer organisation DECO points out that the rateable value depends on the age of the building, but the tax office does not update it automatically. As a result, some owners pay more than they would after a new valuation. You can request a new valuation, but only by doing the sums will you know whether it is worth it.
