The deadlines for paying IMI vary depending on the amount to be paid.
The deadlines for making the property tax payment are as follows:
Up to 100 euros: just a single instalment, paid in May;
Between 100 and 500 euros: two instalments, paid in May and November;
From 500 euros: three instalments, paid in May, August and November.
This means that the deadline for paying the tax only ends on August 31 for property owners whose tax is more than 500 euros.
