This decision allows families to immediately benefit from the new tax reduction, anticipating the effect of the IRS cut approved by Parliament, which takes effect from January 1, 2026. Without this measure, the benefit would only be realized in the tax settlement in 2027.
The decree approving the adjustments to the IRS withholding tables for November 2026 has already been published in the Diário da República.
In December, the currently applicable withholding tax tables will be reinstated.
