Portugal vs UK Tax for Expats 2026 - After the Non-Dom Abolition

For British expats - and Americans/others considering both - the Portugal vs UK tax decision changed fundamentally on April 6, 2025. That’s when the UK abolished the centuries-old “non-dom” regime that had let foreign-domiciled UK residents shelter foreign income from UK tax indefinitely. In its place: the Foreign Income and Gains (FIG) regime, a 4-year window of full relief for new UK arrivals.

This guide compares Portugal and UK for 2026, with full coverage of the new FIG regime and side-by-side numbers at typical income levels.

The headline numbers

Personal income tax rates (2026):

Tax point	Portugal (IRS)	UK (Income Tax + employee NI)
Personal allowance	None (mínimo de existência €12,880)	£12,570 (tapered above £100k)
Lowest bracket	12.5% (up to €8,342)	0% (up to £12,570) → 20% (£12,570-£50,270)
Bracket at £50k / €58k	44.6% (PT marginal)	40% (UK marginal)
Top bracket	48% (above €86,634)	45% (above £125,140)
Solidarity / extra	+2.5% above €80k, +5% above €250k	Personal allowance taper effective +20% on £100k-£125k slice
Employee SS / NI	11% flat	8% (£12,570-£50,270) / 2% (above £50,270)

UK income tax 2026:

• £0 - £12,570: 0% (personal allowance)
• £12,571 - £50,270: 20%
• £50,271 - £125,140: 40%
• Above £125,140: 45%

The UK personal allowance is the largest structural difference: the first £12,570 (~€14,500) is completely tax-free. Portugal’s mínimo de existência (€12,880) achieves something similar but only as a backstop, not a band.

UK NI rates are also lower than PT SS at most income levels. NI tops out at 2% above £50,270 - meaningfully cheaper than Portugal’s 11% across the whole income range.

Who’s lower at each income level?

Currency conversion at GBP 1 = €1.16 (rough 2026 rate). Numbers rounded.

£30,000 / €34,800 single employee:

• Portugal: IRS €4,890 + SS €3,830 = €8,720 (25.1%)
• UK: Income Tax £3,486 + NI £1,394 = £4,880 (€5,660, 16.3%)

UK saves ~£3,000 / €3,500 per year. UK personal allowance + lower NI + lower 20% basic rate dominate.

£60,000 / €69,600 single employee:

• Portugal: IRS €13,990 + SS €7,660 = €21,650 (31.1%)
• UK: Income Tax £11,486 + NI £3,394 = £14,880 (€17,260, 24.8%)

UK saves ~£3,800 / €4,400 per year. The UK 40% bracket starts later than the Portuguese 44.6% bracket, and NI’s 2% above £50k is much cheaper than Portuguese 11%.

£100,000 / €116,000 single employee:

• Portugal: IRS €36,920 + SS €12,760 = €49,680 (42.8%)
• UK: Income Tax £27,432 + NI £4,394 = £31,826 (€36,920, 31.8%)

£100k single employee

~£11,000 / year

At £125,140+ where the UK 45% additional rate kicks in: the gap narrows. At £150,000:

• Portugal: ~€68,800
• UK: ~£52,200 (≈€60,500)

UK still ~€8,000 cheaper, but converging.

At all standard-regime income levels, UK is cheaper than Portugal for employees. The personal allowance, lower employee NI, and lower bracket structure all favor the UK.

Freelancers / self-employed

UK self-employed: Pay Income Tax on profit (revenue minus expenses) at standard bands, plus Class 2 NI (£3.50/week if profits > £6,725) and Class 4 NI (6% on £12,570-£50,270, 2% above). VAT registration required if revenue > £90k.

Portugal recibos verdes: Year-1 stack (50% IRS reduction + 12-month SS exemption), then Cat B simplified (75% taxable presumption, 21.4% SS on 70% base).

£40,000 / €46,400 freelancer, Year 1:

Component	Portugal (Year 1)	UK (sole trader)
Income tax / IRS	€2,180 (37.5% × €46.4k → IRS)	£5,486 (£40k − £12.57k allowance × 20%)
Social Security / NI	€0 (year-1 exemption)	£1,829 (Class 4 6% × £30,477 + Class 2 £182)
Total	€2,180 (4.7%)	£7,315 (€8,490, 18.3%)

Portugal year-1 wins by ~€6,300 / £5,400. UK has no equivalent year-1 exemption.

£40,000 / €46,400 freelancer, year 3+:

• Portugal: IRS ~€7,400 + SS ~€6,950 = €14,350 (30.9%)
• UK: Income Tax £5,486 + NI £1,829 = £7,315 (€8,490, 18.3%)

By year 3, UK is meaningfully cheaper than Portugal for self-employed at this income level - primarily because UK Class 4 NI maxes at 2% above £50k while Portuguese Cat B SS continues at 21.4% × 70% base.

Special regimes - the post-2025 picture

UK FIG regime (effective April 6, 2025):

For “new arrivers” - those who haven’t been UK tax-resident in any of the last 10 years:

• 100% relief on foreign income and foreign capital gains for the first 4 tax years of UK residence
• Must explicitly claim FIG each year; claiming forfeits personal allowance, capital gains annual exempt amount, and certain reliefs
• After year 4: full UK taxation on worldwide income (no transition)
• Replaces the entire pre-2025 non-dom / remittance basis system

Portugal NHR (legacy, closed since 2024-01-01):

• 20% flat on PT-source qualifying income, 10 years
• Most foreign income exempt
• 10% flat on foreign pensions

Portugal IFICI (2024+ replacement):

• 20% flat on PT-source qualifying income, 10 years
• Most foreign income exempt (similar to NHR)
• Narrower eligibility (R&D / innovation / university)

Comparison: 4-year UK FIG vs 10-year Portugal NHR/IFICI:

Feature	UK FIG	Portugal IFICI
Foreign income relief	100% exempt	100% exempt (most categories)
PT/UK-source income	Standard rates	20% flat (qualifying)
Duration	4 years	10 years
Eligibility	10-year UK-non-resident requirement	5-of-6-year PT-non-resident requirement + IFICI activity
After window	Full standard rates kick in	Full standard rates kick in

For someone with significant foreign passive income (US/UK dividends, foreign rental, foreign business income):

Years 1-4: UK FIG and Portugal IFICI both exempt foreign income. Roughly tied. Years 5-10: Portugal IFICI continues exempting foreign income at 20% flat on PT-source. UK FIG ends - full UK taxation kicks in. Years 11+: Both lose preferential treatment, full standard rates.

Portugal saves ~6 years of foreign-income exemption vs the UK if you stay long-term. This is meaningful - for a £100k/year foreign dividend stream, the difference can exceed £200,000 over the 10-year window.

UK FIG wins when:

• You’re staying 4 years or less (matching FIG window)
• You don’t qualify for IFICI (general professional services)
• You strongly prefer UK lifestyle / language / family ties

Portugal NHR/IFICI wins when:

• You’re committing 5+ years
• Your work qualifies for IFICI (genuine R&D / research / qualified ICT)
• You’re an existing NHR holder
• You have ongoing foreign income that you want exempt for the long haul

Inheritance tax - Portugal’s clear win

This is the structural difference that grows in importance with wealth and age.

UK Inheritance Tax (IHT):

• 40% on estate value above £325,000 (frozen until 2030)
• Spouse/civil-partner transfers exempt
• Residence Nil Rate Band: additional £175k if leaving primary residence to direct descendants
• Effective combined nil-rate-band: up to £500k per person (£1M for a couple)
• Various reliefs: 7-year gift rule, Business Property Relief, Agricultural Property Relief

Portugal:

• No inheritance tax between direct relatives (spouse, children, parents, grandchildren)
• 10% Imposto de Selo on transfers between non-direct relatives (siblings, friends, cousins)

For a £2 million estate passed to a single child:

• UK: ~£600,000 IHT (after nil-rate-bands and standard reliefs)
• Portugal: £0

This is permanent - even after NHR/IFICI ends, Portugal’s no-inheritance-tax-for-direct-relatives stays in effect. For wealthy expats with adult children, Portuguese tax residence often makes sense purely on inheritance grounds, regardless of income tax math.

Caveat for British expats: UK domicile is not tax residence. You can be PT tax resident and still UK-domiciled (and thus UK-IHT-exposed on worldwide assets) for years after moving. The new 2025 rules link IHT exposure to long-term UK residence (10 of last 20 years for “long-term resident” status), so genuine emigration to Portugal eventually gets you out of UK IHT - but slowly.

Other taxes - VAT, property, vehicles, capital gains

Tax	Portugal	UK
VAT (standard)	23%	20%
VAT (intermediate)	13%	5% (specific items only)
VAT (reduced)	6%	0% (essentials)
Property tax (annual)	IMI 0.3-0.45% of VPT	Council Tax (band-based, ~£800-£3,500/year)
Property purchase	IMT 0-8% + Selo 0.8%	SDLT 0-12% (with first-home relief, surcharges)
Capital gains	28% flat	10/20% (basic/higher rate) on most; 18/24% on residential property; 24% on carried interest
Capital gains personal exemption	None	£3,000/year (2026, post-cuts)

UK CGT is structurally friendlier than Portugal’s flat 28% for basic-rate taxpayers (10%) and roughly tied for higher-rate taxpayers (20%). For property, UK 24% beats Portugal’s 28%.

VAT in the UK is 3pp lower across the board - small but compounds for high consumption.

Worked total: £60,000 single freelancer, Year 3

Tax	Portugal	UK (sole trader)
Income tax	€13,990	£11,486 (€13,320)
Social Security / NI	€10,420	£2,279 (€2,640)
VAT on £30k consumption	~€5,000	~£3,800 (€4,400)
Vehicle tax	€150	£180 (€210)
Property tax (£200k home)	€700	£1,400 (€1,620)
Total annual	~€30,260 (43.5%)	~£19,145 / €22,200 (31.9%)

UK saves ~£8,000 / €8,000 per year for established freelancers in standard regime. The Class 4 NI cap above £50,270 is the dominant factor.

When to choose which

Choose Portugal if:

• You have significant foreign passive income and plan to stay 5+ years - IFICI’s 10-year exemption beats UK FIG’s 4-year window
• You have substantial wealth or older parents with significant estates - no inheritance tax for direct relatives is structural and permanent
• You qualify for IFICI (genuine R&D / research / university work)
• You’re an existing NHR holder - irreplaceable
• You’re a first-year freelancer - the year-1 stack is real
• You prefer the climate, cost of living, or specific Portuguese cities

Choose UK if:

• You’re a high-earning standard-regime employee - UK income tax + NI is consistently 5-15% cheaper than Portuguese standard
• You’re staying 4 years or less - FIG covers exactly that window
• You don’t have significant foreign passive income - FIG vs NHR/IFICI doesn’t matter
• You’re already UK-domiciled and want to stay close to family/business ties
• You prefer English-language services, NHS familiarity, or specific UK cities

Toss-up:

• Mid-income employees (£30k-£60k) with no special regime: UK is 3-5pp cheaper but lifestyle factors dominate
• Pensioners: depends on pension type and amount; both countries offer reasonable treatment

Common comparison mistakes

Using pre-2025 UK non-dom information. The remittance basis is gone for new arrivals from April 6, 2025. Articles published before that date describe an obsolete regime.

Ignoring inheritance tax. UK 40% IHT above £325k is one of the highest IHT rates in the world. Portugal’s 0% for direct relatives represents potentially hundreds of thousands of pounds in lifetime savings for wealthier families.

Forgetting the personal allowance taper. UK personal allowance reduces by £1 for every £2 above £100k earned. Effective marginal rate on £100k-£125k is 60% - worse than any Portuguese bracket. This wipes out some of the UK tax advantage at this specific income range.

Mixing UK domicile with UK tax residence. Old UK domicile rules persisted until April 2025; new long-term-resident rules (April 2025+) link IHT exposure to actual UK residence history. A British citizen who’s been PT tax resident for 6+ years has genuine reduced UK-IHT exposure on non-UK assets.

Comparing UK FIG to NHR pensioner regime. NHR’s 10% pensioner rate is closed to new applicants (since 2024). Greek 5A’s 7% pensioner regime is now the better European alternative for foreign pension income.

Run your own numbers

The TAXCLARA calculator handles the Portuguese side. For the UK side, HMRC’s Personal Tax Account simulator is the best official source. For inheritance modeling, the difference is dramatic enough that running both sides through the calculator and your own back-of-envelope IHT estimate will be informative.

For broader context: see the Portugal vs Spain comparison (Beckham Law), the Portugal vs Italy comparison (impatriati), and the Portugal vs Greece comparison (Article 5A pensioner regime).
