The Tax Authority has closed the door on any flexibility regarding deadlines for reinvesting capital gains in a primary residence to qualify for an IRS exemption. In a recent binding ruling, the Tax Authority concluded that delays in urban planning licensing—even when proven—do not justify extending the 36-month legal deadline.

The IRS withholding tables (tabelas de retenção na fonte) are government-published schedules that determine how much personal income tax (Imposto sobre o Rendimento das Pessoas Singulares — IRS) employers must deduct from each paycheck. They take into account gross pay, marital status, number of dependents, and disability status.
The tables are updated annually (and sometimes mid-year when budgets change), directly affecting monthly take-home pay. When tables are revised downward, workers see more in their pay packet; when raised, less. Any difference between amounts withheld and the actual tax owed is settled when the annual IRS return (Modelo 3) is filed, typically between April and June.
Employees and pensioners should check the current tables — published by the Autoridade Tributária e Aduaneira (AT) — whenever they change, as the impact on net income can be significant.
Capital gains (mais-valias) are the profits earned from selling an asset, such as a home, for a higher price than it was bought. In Portugal, residents can often avoid paying tax on these gains if they reinvest the full sale proceeds into a new primary residence within 36 months. The Tax Authority (Autoridade Tributária) recently confirmed this deadline is absolute and does not account for external delays like slow building permits.
