Portugal's government has released its new IRS rates, broken down by income bracket and by tax regime, according to Público. The tables, published on Friday, September 18, 2026, set out how much more taxpayers could receive over the course of a year under the revised schedule. Público also published simulations alongside the rates so readers can see how the changes apply to different earnings levels.
The government's own website has posted simulation tools as well, letting taxpayers work out what they stand to save. Expresso reported on the same release, framing it around the question of how much a household gains from the latest cut. The rates and the simulations together form the practical side of the announcement: not just the percentages, but the euro amounts attached to each tier.
The tax changes arrive as part of a wider set of measures the government has presented against the rising cost of living, a plan covered by Euronews. In a separate announcement, Prime Minister Montenegro set out support measures on fuel prices while rejecting what he described as repeating a past mistake, according to RTP. The IRS tables are the most concrete element so far, since they allow earners to check their own position rather than rely on aggregate figures.
For now, the detail available is limited to the published rates and the accompanying simulations. What remains to be seen is how the new brackets translate into actual withholding on payslips in the coming months, and whether the government's broader cost-of-living package moves beyond the fuel measures Montenegro has already outlined.
