Portugal has just cut income tax again, and this time the cut is backdated to 1 January. If you are a British resident here, the Portugal income tax cut 2026 will reduce your bill for this year, but probably not in the way the headlines suggest, and for most UK pensioners not this month.

I have had a run of messages from clients this week asking why their neighbour’s pension went up in November and theirs did not. The answer sits in the difference between a tax cut and a change to tax withholding. In this article I will walk through what has changed, who actually gains, roughly how much, and what is still only a proposal for 2027.

What has actually changed with the Portugal income tax cut 2026

Two separate things have happened, and they are easy to muddle.

First, the government has made an extraordinary cut to IRS (Imposto sobre o Rendimento das Pessoas Singulares, which is Portuguese personal income tax). The rates for the first six of the nine income bands have been reduced by between 0.3 and 0.5 percentage points. Parliament authorised the change in late October, the Council of Ministers approved the decree-law at the end of the month, and it applies to income earned from 1 January 2026.

Second, to get some of that money into pockets before Christmas, the tax withheld from Portuguese salaries and pensions paid in November 2026 has been halved for one month only. Normal withholding returns in December.

The first is a real reduction in the tax you owe for the year. The second is only a matter of timing, and I will come back to why that matters.

The new IRS rates for 2026 income

Based on the published figures, this is how the general rates for 2026 now look. The band thresholds are the ones already in force for 2026; only the rates in the first six bands have moved.

Taxable income (2026)	Previous rate	New rate
Up to €8,342	12.5%	12.2%
€8,342 to €12,587	15.7%	15.2%
€12,587 to €17,838	21.2%	20.7%
€17,838 to €23,089	24.1%	23.6%
€23,089 to €29,397	31.1%	30.6%
€29,397 to €43,090	34.9%	34.6%
€43,090 to €46,566	43.1%	43.1% (unchanged)
€46,566 to €86,634	44.6%	44.6% (unchanged)
Over €86,634	48%	48% (unchanged)

Portugal taxes income in slices, so higher earners benefit too. Someone whose income reaches the top bands still pays the lower rates on the slices that fall into the first six.

The government describes this as the sixth IRS reduction since April 2024 and says around three million households will benefit. One caveat: Madeira and the Azores set their own reduced rates, so the figures above are for the mainland.

How much is the cut worth in practice?

This is where I would gently manage expectations. A cut of 0.3 to 0.5 percentage points is welcome, but it will not change anyone’s retirement.

Here are my own calculations using the table above. They are per person, on taxable income (that is, income after the standard deductions), and they ignore other reliefs, so treat them as illustrations rather than a forecast of your own bill.

• Taxable income of €20,000: a saving of roughly €83 for the year.
• Taxable income of €30,000: a saving of roughly €132 for the year.
• Taxable income of €43,090 or more: a saving of roughly €171 for the year, which is the most any one person can gain from this change.

Married couples and those in a recognised civil partnership who file jointly have their income split between them before the bands are applied. In that case the saving can apply to each half, so a couple could gain up to around twice the single figure.

So the realistic answer for most of my clients is somewhere between the cost of a good lunch and a modest weekend away. Worth having, but not worth reorganising your finances around.

Why most UK pensioners will not see more money in November

This is the part that has caused confusion. The halved withholding in November applies to tax deducted at source by Portuguese employers and Portuguese pension payers. If you work for a Portuguese company or receive a Portuguese pension, you should see a higher net payment this month.

Most British retirees here are in a different position. Your UK private or workplace pension is typically paid gross from the UK once HMRC has issued an NT (no tax) code, and your UK State Pension is paid gross anyway. Nobody is withholding Portuguese tax from those payments each month, so there is nothing to halve.

Instead, you declare that income on your annual Portuguese return (the Modelo 3), filed between April and June for the previous year. That is when the rate cut reaches you: when your 2026 income is assessed in 2027, the new lower rates will be used.

If you are still having UK tax deducted from a pension that should be taxable only in Portugal under the double taxation agreement, that is a separate issue and one worth fixing. HMRC’s guidance on tax on your UK income if you live abroad is the place to start.

A halved withholding is not a halved tax bill

For readers who do have Portuguese salaries or pensions, please do not read November’s payslip as a sign of things to come. Withholding is simply an advance payment towards your final bill for the year.

Because the rate cut is backdated to January, you have been over-paying slightly through withholding for ten months. Halving November is the government’s rough-and-ready way of handing that back now, rather than making you wait for a refund in 2027.

The flip side is that it is blunt. For some people, one halved month will hand back more than the cut is actually worth. If that is you, expect a smaller refund than usual next summer, or possibly a little to pay. It is sensible to keep that in mind rather than treating the extra as a windfall.

Reports also indicate the halving does not apply to very high earners (salaries above roughly €20,000 a month and pensions above roughly €18,000 a month), and that employers who miss it can correct the position in later payments before the end of December.

Who will not benefit from the rate cut?

Not every expat’s income is taxed on the standard bands, so not everyone gains.

• NHR holders: if you still have Non-Habitual Resident status, your foreign pension income is generally taxed at a flat 10% (or exempt, for those registered before the 2020 change who kept the older terms). That flat rate has not changed.
• UK government service pensions: most civil service, armed forces, police, fire, teachers’ and local government pensions remain taxable only in the UK under the treaty, unless you are a Portuguese national. A Portuguese rate cut does not directly reduce the tax on them.
• Income taxed at flat rates: savings interest, dividends and most investment gains are normally taxed at a flat 28% unless you choose to add them to your other income. The 28% rate is not part of this change.
• Very low taxable incomes: if your income is already below the level at which IRS is due, there is no tax to cut.

There is one planning point hidden in that list. Because the scale rates are a little lower, the choice between paying the flat 28% on investment income or opting to aggregate it with your other income (known as englobamento) shifts very slightly in favour of aggregating for people on modest incomes. It is a marginal change, but it is worth your accountant re-running the numbers when your 2026 return is prepared.

What is proposed for 2027 (and not yet law)

Separately, the government’s State Budget proposal for 2027 was submitted to Parliament on 8 October. The headline income tax measures in the proposal are:

• the band thresholds rising by about 3.88%, so that pay and pension increases are less likely to push you into a higher band;
• the reduced rates above carried forward into 2027;
• an increase in the minimum income level below which no IRS is paid.

Under the proposal, the first band would run up to €8,666 and the top 48% rate would start at €89,995.

I want to be plain about the status of this. The budget passed its first general vote in late October, and the final overall vote is planned for 24 November. Until that vote has happened and the law is published, the 2027 figures are proposals and can still be amended. I will update readers once the final version is confirmed.

For UK pensioners there is a quiet benefit in the threshold increase. Your pension arrives in sterling, so its euro value moves with the exchange rate as well as with annual increases. Wider bands give a little more headroom before more of your income falls into a higher slice.

What should UK expats do now?

For most people the honest answer is: very little, but check a few things.

1. If you have a Portuguese salary or pension, look at your November payment. If the withholding has not been reduced, ask your employer or pension payer, as corrections can be made in December.
2. Do not spend the difference twice. The November boost and next year’s refund come from the same pot.
3. Keep your 2026 records tidy. UK pension statements, P60s, bank interest and dividend vouchers will all be needed for your Modelo 3 next spring. The return is filed through the Portal das Finanças.
4. Review withdrawals before 31 December. Portugal’s tax year is the calendar year. If you are drawing flexibly from a UK pension, how much you take before year end decides which bands it lands in. With slightly lower rates and wider bands proposed for 2027, timing can make a modest difference.
5. Check your regime. If your NHR status is ending soon, the standard bands above are what you will move on to, so it is worth understanding them before that happens.

Frequently Asked Questions

Does the Portugal income tax cut 2026 apply to my UK pension?

Yes, if you are a Portuguese tax resident and your UK pension is taxed in Portugal at the standard scale rates. The lower rates will be applied when your 2026 income is assessed in 2027. It does not apply to pension income taxed at the flat NHR rate, or to UK government service pensions that are taxable only in the UK.

Why did my pension not go up in November?

The halved November withholding only affects tax deducted at source in Portugal. UK pensions paid gross from the UK have no Portuguese tax withheld each month, so there was nothing to reduce. You receive the benefit of the rate cut through your annual tax return instead.

Will I get a bigger tax refund in 2027?

Not necessarily. If you had Portuguese tax withheld, November’s reduction has already handed some of the saving back, so your refund could be similar or even smaller. If you pay your tax through the annual return, your final bill should simply be a little lower than it would otherwise have been.

Are the 2027 tax bands confirmed?

No. They are part of the State Budget proposal for 2027, which is still going through Parliament, with the final vote planned for 24 November 2026. The figures could change before the law is published.

Do I need to do anything to claim the cut?

No. There is no application. The new rates are applied automatically when the tax authority calculates your 2026 assessment after you file your return.

What to Do Next

Portugal’s 2026 income tax cut is real and backdated, but modest: at most around €170 per person for the year on my calculations. The halved November withholding is a timing change for people paid in Portugal, not an extra cut, and most UK pensioners will see the benefit through next year’s return instead. The 2027 changes look helpful but are not yet law.
