IMI in Lagos: the rate is set per parish
The municipality of Lagos (Faro district) does not set a single IMI rate: it sets one per freguesia. So there is no figure here — printing a zero would be printing something untrue. Your own rate is on the Autoridade Tributária bill and at the câmara municipal.

Why there is no figure
8 of the 308 municipalities do not report a single rate to the Autoridade Tributária: they report one per freguesia. The cell stays empty and we say why, instead of filling it with a zero nobody pays.
Median price per m² in Lagos
In Lagos the median sale value of family dwellings was 3 855 € per m². It is a 12-month median; the last quarter counted is Q1 2026.
- New housing only: 4 131 € per m².
- Existing housing only: 3 727 € per m².
- Flats only: 3 797 € per m².
It is the median of sale prices registered with the tax authority, not of asking prices in listings: what was paid, not what is wanted. It covers family dwellings of 20 m² gross private area and above.
It is not a valuation of your property. Half of the sales in the municipality were above this figure per m² and half below; what one flat is worth depends on the street, the floor, the condition and the year.
INE recalculates these figures retrospectively: the same quarter can change after publication. What stands here is always the latest figure according to INE; the date below is when INE last updated the indicator, not the date this quarter was recomputed.

Purchasing power in Lagos
Purchasing power per capita in Lagos is 94.37, on a scale where Portugal = 100 (2021).
It measures how much is bought per resident against the national average: 100 is the country average, above is more, below is less. It is not income or wages — it is an index combining consumption and purchasing capacity.

How the rate changed
Lagos set no single rate in any of the verified years — it sets one per freguesia, so there is no series to show.
What the municipality decides and what the law decides
The rate on urban property is set by the municipality itself, but not freely: the law fixes the range from 0,3 % to 0,45 % (CIMI, article 112.º, n.º 1). For rural property there is no choice at all — the rate of 0,8 % is written into the same paragraph.
The municipal assembly decides, and it decides for each year. It may also set the rate per freguesia instead of for the whole municipality — which is why 8 of the 308 have no single rate (article 112.º, n.º 5).
If the municipality does not report its decision to the Autoridade Tributária by 31 December, the minimum rate of 0,3 % applies (article 112.º, n.º 14). That is one reason why 199 of the 300 municipalities with a single rate sit exactly on the lower bound.
The rate on one particular property can still go up: tripled for property left vacant for more than a year and for ruins (n.º 3); in urban-pressure zones, by up to 100 % for short-term rental and up to 25 % for housing that is neither let nor the owner's own permanent home (n.º 19), and that increase rises to 50 % where the owner is a company (n.º 20); by up to 30 % for dilapidated buildings (n.º 8).
And it can go down: by up to 30 % in urban-regeneration or depopulation-relief areas (n.º 6), by up to 20 % for let urban property (n.º 7), by up to 50 % for buildings of public interest or cultural heritage (n.º 12).
When it is paid
The tax is for the previous year and is owed by whoever was on record as owner on 31 December of that year (article 113.º, n.º 1). The 2025 rate on this page is the bill that arrives in 2026.
The Autoridade Tributária issues the assessment in February and April of the following year (article 113.º, n.º 2).
It is paid in instalments, and how many depends on the amount (article 120.º, n.º 1): up to and including 100 €, one instalment in May; above 100 € and up to 500 €, two, in May and November; above 500 €, three, in May, August and November.
Missing one instalment makes the rest fall due immediately (article 120.º, n.º 4).
If the tax to be collected comes to less than 10 €, no assessment is issued at all (article 113.º, n.º 6).
