On the standard rules the UK wins at every salary, and Portugal has the heaviest burden of any market we compare against it. At the equivalent of £200,000 a Portuguese employee keeps 49.8% of gross.
The gap is widest in the middle, at about 15.3 points around £50,000, which is exactly where most people moving for work land. What changes the answer is IFICI, and most people who assume they qualify do not.

This is the share of gross kept after IRS and employee Segurança Social. It does not depend on the exchange rate, which makes it the durable way to compare the two systems.
| Equivalent salary | UK keeps | Portugal keeps | Gap |
|---|---|---|---|
| £30,000 | 83.7% | 70.7% | 13.1 pts |
| £50,000 | 79.0% | 63.7% | 15.3 pts |
| £80,000 | 71.2% | 58.2% | 13.0 pts |
| £120,000 | 63.5% | 53.6% | 9.9 pts |
| £200,000 | 58.9% | 49.8% | 9.1 pts |
Notice the shape: the gap grows to £50,000 and then shrinks. That is not Portugal easing off, it is the UK catching up as the personal allowance tapers away above £100,000. Portugal's own column falls steadily throughout, because employee Segurança Social is a flat 11% with no ceiling and IRS runs up to 48%.
IFICI changes the arithmetic entirely
IFICI, the regime that replaced non-habitual residency from 1 January 2025, taxes qualifying employment income at a flat 20% IRS for ten years. Against progressive rates reaching 48%, that is transformative at the top of the range.
| Portuguese gross | Progressive | Under IFICI | Extra a year |
|---|---|---|---|
| €58,450 | 63.7% | 71.2% | €4,355 |
| €93,520 | 58.2% | 71.2% | €12,114 |
| €140,280 | 53.6% | 71.2% | €24,692 |
Under IFICI the share kept is flat at about 71.2% regardless of salary, because a flat IRS rate and a flat 11% social security produce a flat total. That is a completely different animal from the progressive column, and it is why the regime question matters more than the country question here.
IFICI is much narrower than the old NHR
Do not assume you qualify because you read about NHR. IFICI is restricted to highly qualified activities in scientific research and innovation, covering specified roles in science, technology, healthcare, education and green energy. You must not have been a Portuguese tax resident in the previous five years, you must work in a qualifying activity each year to keep the benefit, and pensions are no longer exempt as they were under NHR. Our IFICI guide works through the eligibility in detail.
How these figures were produced
The progressive figures are PayMetric Labs' own calculations with our UK and Portuguese tax engines at 2026 rates, for a single filer with no dependants on mainland Portugal. The IFICI column is our own calculation applying the flat 20% IRS rate to the same net employment income base the engine derives, plus the standard 11% employee Segurança Social; our Portuguese engine models the progressive regime, so treat the IFICI figures as a well-founded estimate rather than an engine output. Converted at £1 = €1.1635, European Central Bank reference rates, 23 September 2026.
Fourteen payments, not twelve
Portuguese employees receive holiday and Christmas subsidies on top of monthly salary, so an annual package normally runs across 14 payments. Multiplying a monthly Portuguese figure by 12 understates the package by roughly 17%, which is large enough to change an offer decision on its own.
Ask which basis a quoted salary uses before comparing it with anything. Our guide to the subsídio de férias and subsídio de Natal covers how the two subsidies are paid and taxed.

Frequently asked questions
Does the UK or Portugal leave you with more of your salary?
The UK, at every salary level, and by more than most people expect. At the equivalent of £50,000 a UK employee keeps 79.0% of gross against 63.7% in Portugal, a gap of 15.3 percentage points. Portugal has the heaviest headline burden of any market we compare against the UK, keeping only 49.8% at the equivalent of £200,000.
Where is the gap widest?
In the middle, at around £50,000, not at the top. Portugal's IRS brackets rise steeply through ordinary professional salaries, so the squeeze is hardest exactly where most people moving for work will land. The gap then narrows above £100,000, because the UK's personal allowance taper starts dragging the UK side down.
What is IFICI and does it change the answer?
Completely, if you qualify. IFICI, sometimes called NHR 2.0, replaced the old non-habitual resident regime from 1 January 2025. It taxes qualifying Portuguese employment income at a flat 20% IRS for ten years instead of progressive rates that reach 48%. On the equivalent of £120,000 that lifts what you keep from 53.6% to about 71.2%, worth roughly €24,692 a year.
Will I qualify for IFICI?
Probably not, and this is the part that catches people. IFICI is far narrower than the old NHR. It is restricted to highly qualified activities in scientific research and innovation, which in practice covers specified roles in science, technology, healthcare, education and green energy. You must also not have been a Portuguese tax resident in the previous five years, and you have to work in a qualifying activity each year to keep it. Pensions, which the old NHR exempted, are no longer covered.
Are Portuguese social security contributions high?
The employee rate is a flat 11% of gross with no ceiling, which is simpler than the UK's banded National Insurance but keeps accruing on every euro. The employer pays considerably more on top. The absence of a ceiling is part of why Portugal's effective rate keeps climbing rather than flattening the way Germany's or Brazil's does.
Does Portugal pay 14 months rather than 12?
Yes, and it materially changes an offer comparison. Portuguese employees receive holiday and Christmas subsidies, so an annual package is normally expressed across 14 payments. A monthly Portuguese figure multiplied by 12 understates the package by about 17%. Ask whether a quoted salary is the 12-month or 14-month basis before comparing it with a UK number.
How reliable is the currency conversion here?
Treat it as illustrative and check the live rate. The percentages are the durable part of this comparison, because the share of gross you keep does not depend on the exchange rate. The rate used is stated and dated beside the cash table above, and comes from the European Central Bank's daily reference rates.
What does this comparison leave out?
UK pension salary sacrifice and student loan repayments. Portuguese dependants and the many IRS deductions available on the progressive regime. The holiday and Christmas subsidies, which favour Portugal. Regional rates, since Madeira and the Azores differ from the mainland. And cost of living, which is the main reason people consider the move in the first place.
Figures are PayMetric Labs' own calculations using our UK and Portuguese tax engines at 2026 rates, for a single filer with no dependants on mainland Portugal and a single UK taxpayer with no pension contributions or student loan. IFICI figures are our own estimate applying the 20% flat rate, verified against the regime rules in September 2026. Holiday and Christmas subsidies are excluded.
