Key figures — as of 2026-10-15: Despacho n.º 12523-A/2026 (14 October) halves IRS withholding on salaries and pensions paid between 1–30 November 2026, including the Christmas subsidy — relief applies up to €20,221/month gross for single taxpayers and €20,468/month for married couples — standard tables (Despacho n.º 233-A/2026) resume automatically from 1 December 2026 — underlying 2026 rate cuts of 0.3–0.5 percentage points across brackets 1–6 apply retroactively from 1 January 2026.
The despacho, in plain terms
Portugal's Ministry of Finance published Despacho n.º 12523-A/2026, approving adjustments to the IRS withholding tables for November 2026. The timing matters: it lands the week before payroll runs for November, so companies across the country have to apply it immediately.
What's unusual is the mechanism. Rather than issuing brand-new rate tables, the Government opted to halve the tax deducted from eligible earnings under the existing rules instead of introducing revised monthly withholding tables, as it had done in previous years when similar mid-year cuts required employers to update payroll software. In practice, payroll departments take whatever the January 2026 table says is owed and simply deduct half of it for the month.
The relief isn't limited to base salary. The Government decided to cut IRS withholding by 50% to reflect the extraordinary tax reduction approved by Parliament, which lowers rates on the first six brackets by between 0.3 and 0.5 percentage points, and crucially this applies to both salaries and pensions paid in November, including the Christmas subsidy.
Why it's happening now
Parliament approved a further IRS cut effective from the start of the year, but the mechanics of adjusting withholding tables mid-cycle meant workers hadn't yet felt it in their payslips. The Government's own communication frames it directly: the move allows the Christmas subsidy paid that month to benefit too, letting families enjoy the new tax reduction immediately, after Parliament approved a new IRS cut with effect from 1 January 2026.
The underlying rate changes break down as a 0.3 percentage-point cut in the first bracket to 12.2%, and 0.5 point cuts from the second to fifth brackets, bringing them to 15.2%, 20.7%, 23.6% and 30.6%, with the sixth bracket trimmed by a further margin. Because Portugal operates a progressive income tax system, the lower rates also benefit taxpayers in higher brackets on the portions of their income taxed at the reduced levels — so this isn't just a low-earner story.
Who qualifies, and who doesn't
There's a ceiling. Single taxpayers with gross monthly salaries above €20,221 must still pay the full withholding in November, while for married taxpayers the threshold sits at €20,468. Below those levels, the discount applies automatically — no form, no opt-in, nothing to file with Finanças.
Real numbers help here. A single worker without dependents on a €1,000 gross salary normally has €35 withheld for IRS each month; in November that drops to €18, or stays at €35 if they receive the full Christmas subsidy that month. Scale that up: on a €1,500 salary, the usual monthly withholding of €168 would have been €336 in November once the Christmas subsidy is added — the 50% cut brings that back down to €168, putting an extra €168 in the worker's pocket.
GrowIN's calculation: mid-range earners feel it too
Using the official 2026 withholding table, a single employee without dependents earning close to €2,499 gross sits at an effective monthly withholding rate of roughly 18.8%, equivalent to about €470 deducted under normal rules. Halve that for November and the worker keeps roughly an extra €235 in that single payslip — before accounting for any Christmas subsidy paid the same month, which could push the one-off gain closer to €470. For a foreign employee on a typical relocation-level salary, that's a meaningful one-month bump landing without any paperwork.
"This is the rare tax change where foreign employees in Portugal don't have to lift a finger to see the benefit — it simply shows up in the November payslip," says GrowIN Portugal Editorial.
Temporary, not permanent
Don't bank on this continuing. The dispatch confirms that the standard withholding tables approved in January will apply again from 1 December 2026, and the relief is temporary, as full withholding rates return in December, meaning workers should not expect the higher take-home pay to continue into the final month of the year. Any gap between what was withheld all year and what's actually owed still gets reconciled at the annual IRS filing between 1 April and 30 June 2027, as always — see our tax & NIF guide for how that annual settlement works for foreign residents.
Worth watching: this one-month measure could be followed by additional savings next year under the Government's proposed State Budget for 2027, submitted to Parliament on 8 October. For now, foreign employees and pensioners on Portuguese payroll just need to check their November payslip — the change should already be there.
