The Municipal Assembly of Santiago do Cacém has approved the reduction of the Municipality's variable participation in IRS from 5% to 4.5%, effective from 2027, representing a tax relief for residents.

The decision, which takes effect in 2027, will allow 0.5% of the settled IRS to remain in the disposable income of the municipality's families. The Municipal Chamber's proposal was approved by the Municipal Assembly following a vote.
The vote saw 16 votes in favour, cast by 12 elected members from the STC – Somos Todos Cidadãos movement, 2 from Chega, 1 from the PS, and 1 from the CDU. There were 14 votes against, with 13 from the CDU and 1 from the Renovar Santiago do Cacém movement.
This measure continues the strategy of tax relief, aiming to balance the reduction of the tax burden with the municipality's financial sustainability.
In the same session, the implementation of the Family IMI (Municipal Property Tax) was also approved. This measure provides fixed reductions in the IMI for households with dependents: 30 euros for one dependent, 70 euros for two, and 140 euros for three or more.
Through these two initiatives, the Municipality of Santiago do Cacém strengthens its support mechanisms for family income, aligning fiscal policy with budgetary balance.
