The Autumn Budget 2026 was delivered on 28 October, and if you are a British expat in Portugal the obvious question is: does any of it actually affect me? The honest answer is “some of it, in ways that are easy to miss”. Most headlines are written for people living in the UK, so this guide picks out what matters for UK expats with pensions, savings or investments.

A quick caveat before we start. Budget announcements are subject to legislation and detail often emerges in the days and weeks afterwards, so I have flagged where something is not yet confirmed. Everything below is based on the early reporting and analysis available at the time of writing.

The Headlines at a Glance

Based on the early analysis from investment and wealth firms, the main points relevant to pensions and savings appear to be:

• Tax on savings and property income rises by a further 2 percentage points from April 2027.
• A new allowance from April 2027 is designed to stop pensioners on the full new State Pension being pushed into income tax. The detailed mechanics, including how it tapers for higher incomes, are still awaited.
• The tax-free pension lump sum is unchanged. It remains 25%, up to the Lump Sum Allowance of £268,275. Cuts had been rumoured but were not announced.
• The planned cut to the cash ISA allowance has been dropped, so the overall annual ISA allowance stays at £20,000.
• Capital gains tax rates and the annual exempt amount were reported as unchanged.
• The full new State Pension is reported to rise by 3.9% to £13,036 a year.
• Income tax thresholds stay frozen until April 2031, and the inheritance tax nil-rate band stays at £325,000.

Now let us look at what each of these means if you live in Portugal.

Pensions: The Lump Sum Is Safe, For Now

Many of my clients were worried that the 25% tax-free lump sum would be cut. It was not, and the Lump Sum Allowance stays at £268,275. For anyone planning to take a lump sum in the next few years, that is a relief, though the fact that a cut was discussed at all is a reminder that pension rules can change quickly.

It is worth remembering that the “tax-free” label applies to the UK. Portugal does not always treat a UK lump sum the same way, so you should always check the Portuguese tax position before taking one. I cover this in more detail in our guide to the UK pension 25% tax-free lump sum and Portuguese tax.

The State Pension Increase

If the reported 3.9% rise is confirmed, the full new State Pension will increase to £13,036 a year. One piece of good news for people in Portugal is that, unlike in some countries, UK State Pensions paid to people living in Portugal are normally uprated each year. If you are drawing a UK State Pension here, you can generally expect the increase.

The new pensioner allowance is aimed at UK taxpayers, so it is unlikely to change your day-to-day position if you are tax resident in Portugal and your pension is taxed there. Where you pay tax on your pension depends on residence and on the UK-Portugal double taxation agreement, and it is something to confirm with an adviser rather than assume.

Savings and Property Income: Check Where You Are Taxed

The rise in tax on savings and property income from April 2027 is the measure most likely to generate headlines. For UK residents it means a higher bill on interest and rental income.

For expats, the key question is where the income is taxed. If you are resident in Portugal, your worldwide savings and investment income is generally taxable in Portugal, with relief for UK tax in certain cases under the double taxation agreement. UK rental income from a property you still own is a different story: the UK normally keeps a right to tax it, so the change may well affect you if you have kept a UK buy-to-let.

If you have UK property, UK savings accounts or UK-based investments, this is a good time to review whether they are still the right home for your money.

ISAs: The Cash Cut Is Off the Table

The earlier plan to reduce the cash ISA allowance has been dropped, which is a relief for UK savers. For UK expats, though, the more important point is unchanged: once you become non-resident you generally cannot pay into an ISA, and you should take advice about what happens to your existing ISAs when you live abroad. Our guide on what happens to your ISA when you move to Portugal is a good starting point.

Inheritance Tax and Pensions

Although it was not a new Budget measure, the rule that most unused pension pots will fall within the scope of UK inheritance tax from 6 April 2027 is now firmly on the horizon. The nil-rate band remains frozen at £325,000.

Whether this applies to you depends on your UK inheritance tax status, which is now based on how long you have been resident in the UK rather than simply your domicile. If you have been away for many years, you may fall outside the UK inheritance tax net, but the transition rules can be complex. Portugal also has its own taxes on inheritance and gifts, so cross-border estate planning is worth doing carefully.

What Should UK Expats in Portugal Do Now?

1. Do not make rushed decisions. Much of the detail is still to come, so wait for the legislation before changing anything major.
2. Review UK-source income. If you receive UK rent or interest, work out how the 2027 changes might affect you and where the income is taxed.
3. Revisit your estate plan. The treatment of pensions in inheritance tax is a good reason to check your beneficiaries and wills in both countries.
4. Check your pension income strategy. If you are planning to take a lump sum or start drawdown, model the Portuguese tax first.
5. Keep your paperwork up to date. Good records make every one of these decisions easier.

Why Budget Timing Matters for Cross-Border Planning

When you live in two tax systems, a UK Budget rarely changes one thing in isolation. A change in the UK can alter how a double taxation agreement applies, which in turn alters the Portuguese bill. That is why I always advise clients to look at the whole picture, rather than reacting to a single headline.

Most of the measures announced take effect from April 2027, which gives you more than a tax year to prepare. In my experience, the people who fare best are the ones who use that time calmly: gathering their pension statements, reviewing where their income is taxed, and making sure their wills and beneficiary nominations are up to date in both countries.

It is also a good moment to think about currency. Many expats draw sterling income but spend euros, and a more settled outlook on UK tax does not remove exchange rate risk. If you have not reviewed how much of your income you convert, and when, it is worth putting that on your list alongside the tax points above.

Frequently Asked Questions

Did the Autumn Budget 2026 change the pension tax-free lump sum?

Based on early reports, no. The 25% tax-free cash remains, up to the Lump Sum Allowance of £268,275. Rumoured cuts were not announced.

Will UK expats in Portugal get the State Pension increase?

UK State Pensions paid to people living in Portugal are normally uprated each year, so you would generally expect to receive the increase once it is confirmed.

Does the rise in savings tax affect me if I live in Portugal?

It depends on where your income is taxed. Portuguese residents are generally taxed in Portugal on their worldwide savings income, but UK rental income may still be taxed in the UK.

Are pensions now subject to inheritance tax?

From 6 April 2027, most unused pension pots are due to fall within the scope of UK inheritance tax. Whether it applies to you depends on your UK residence history, so personal advice is important.

Should I change my plans because of the Budget?

Probably not immediately. Wait for the detail and the legislation, then review your plans with a cross-border adviser.

What to Do Next

For most UK expats in Portugal, the Autumn Budget 2026 is more about the details than the headlines. The lump sum survived, the State Pension rises, and the changes to savings tax and pension inheritance tax are worth planning for rather than panicking over.
