Key figures — as of 2026-09-19: €4.783 billion in spending pressure already locked into the 2027 accounts before a single new measure is added — Draft budget must reach Parliament by 10 October 2026 — Pension spending alone rises almost €2 billion, public-sector wages +€1.23 billion, debt interest +€776 million to ~€6.9 billion — Government has ruled out a fresh income-tax rate cut for 2027, on top of a €401 million IRS revenue drop already baked in from the 2026 reform.
No New IRS Cut This Round
Foreign residents hoping for a repeat of 2026's tax relief should adjust their expectations now. The government has been signalling that there will be no new proposal this year to lower the IRS rate. That's a meaningful shift after last year, when Lisbon widened income brackets and trimmed marginal rates for the second-to-fifth tax bands.
The reason is arithmetic, not ideology. The 2027 State Budget already carries a balance pressure of 4,783 million euros — the value of measures already approved or in force that weigh on next year's accounts, according to the unchanged-policies framework the government handed to Parliament. More than five billion of that is spending-side, driven mainly by pension increases and personnel costs.
For context, last year's equivalent framework for 2026 showed pressure of 4,449 million euros — so this year's starting hole is already wider before ministers write a single new line.
Where the Money Is Going
The breakdown makes clear why tax cuts have slipped down the list. Pension expenditure is expected to rise by almost €2 billion in 2027, while public-sector staffing costs will increase by €1.23 billion. On top of that, the government's debt interest bill is expected to rise by €776 million next year, taking the total interest bill to around €6.9 billion in 2027 — the largest annual rise since 2023.
There's a partial offset: higher salaries and pensions are expected to generate an additional €668 million in personal income tax and €471 million in social security contributions. But that revenue is a byproduct of wage growth, not a policy choice to cut anyone's tax bill.
IRS itself is already running a deficit heading into next year. The government is entering the drafting of the 2027 budget with a €401 million reduction in IRS revenue, before making any decision on tax rates — because the bracket-update rules applied in the 2026 budget to 2026 income only fully materialise in the annual IRS settlement made in 2027, according to public finance expert Carlos Lobo, as reported by ECO.
GrowIN's Reading of the Numbers
Finance Minister Joaquim Miranda Sarmento previously pledged that after the 2026 IRS reduction, the government intends to keep cutting the tax between 2027 and 2029, at a pace of €500 million a year. Set that promise against the €4.783 billion pressure already on the books for 2027, and the ratio is stark: the committed spending overhang is roughly 9.6 times larger than the annual tax-relief pace the government has floated for the coming years. That's GrowIN's own division of the two officially disclosed figures, and it explains why officials are hedging on rates rather than confirming a cut. Sarmento maintains the commitment to lower IRS by €2,000 million by the end of the legislature, but no longer guarantees an additional rate cut in 2027, conditioning it on how the public accounts evolve.
"For anyone budgeting a household in euros, 2027 looks like a standstill year on income tax — the government has the room to defend, not to give," says GrowIN Portugal Editorial.
What Foreign Residents Should Actually Expect
The draft law itself is on a clock. The State Budget proposal for 2027 should enter Parliament by 10 October, and since that date falls on a Saturday this year, it may slide to the first working day of the following week. Once it's tabled, negotiations with opposition parties determine the final shape — last year's budget picked up several late amendments in committee, and this year's minority government will again need votes it doesn't automatically have. The Communist Party has already put pressure on the Socialists over the negotiations, as Portugal's minority Democratic Alliance government navigates a fragile parliamentary arithmetic.
Unions are already lobbying in the other direction. Employers' confederations asked the government to include measures cutting the corporate tax burden and boosting worker housing, while trade unions pushed for IRS relief at pre-budget talks with social partners in mid-September. Whether either side moves the needle on personal income tax won't be clear until the committee-stage votes, typically in late October.
For foreigners already resident or planning a move, this means: don't build a 2027 relocation budget around a lower IRS bill. If you're mid-way through an IFICI application, a D7 or D8 process, or planning your first recibos verdes year, the tax brackets and rates confirmed for 2026 income remain your best planning baseline — check our tax & NIF hub for the current thresholds before assuming anything changes. The one area to watch is the rental-deduction ceiling, already legislated to rise again in 2027, which could offer modest relief to tenants regardless of what happens with income-tax rates.
What to Watch Next
The real test comes once the bill is public: whether Chega, PS or other blocs extract any last-minute IRS concession in exchange for their votes, as happened with 2026's marginal-rate cut. Until then, treat "no IRS relief" as the working assumption for 2027, not a final verdict — Portuguese budgets are rarely settled on the day they're tabled.
