If you're weighing up a career move between London and Milan—or simply curious about how two of Europe's largest economies stack up on personal taxation—this United Kingdom Italy income tax comparison is for you. Understanding which country has lower income tax isn't as simple as glancing at headline rates; allowances, brackets, social contributions, and special regimes all play a role.
In this guide we'll walk through every detail you need for the 2025/2026 tax year, including current brackets, personal allowances, practical salary examples, social security contributions, and tips for expats navigating both systems.
How Income Tax Works in the United Kingdom (2025/2026)
The UK operates a progressive income tax system administered by HM Revenue & Customs (HMRC). For the 2025/2026 tax year (6 April 2025 – 5 April 2026), the key parameters are as follows.
UK Tax Bands and Rates
| Band | Taxable Income (GBP) | Rate |
|---|---|---|
| Personal Allowance | £0 – £12,570 | 0% |
| Basic Rate | £12,571 – £50,270 | 20% |
| Higher Rate | £50,271 – £125,140 | 40% |
| Additional Rate | Over £125,140 | 45% |
Key points:
- The Personal Allowance of £12,570 is gradually withdrawn for individuals earning above £100,000, creating an effective 60% marginal rate on income between £100,000 and £125,140.
- Scotland has its own income tax bands (Starter, Basic, Intermediate, Higher, Advanced, and Top rates) that differ from the rest of the UK.
- Dividends and savings income have their own allowances and rates.

National Insurance Contributions (NICs)
On top of income tax, UK employees pay Class 1 National Insurance at:
- 8% on earnings between £12,570 and £50,270
- 2% on earnings above £50,270
Employers also pay NICs at 15% on earnings above the secondary threshold (£5,000 for 2025/2026), though this doesn't directly reduce take-home pay.
How Income Tax Works in Italy (2025/2026)
Italy's personal income tax—IRPEF (Imposta sul Reddito delle Persone Fisiche)—is also progressive and is administered by the Agenzia delle Entrate. For the 2025 fiscal year (calendar year 1 January – 31 December 2025), the government has confirmed a streamlined three-bracket system.
Italian IRPEF Brackets and Rates
| Bracket | Taxable Income (EUR) | Rate |
|---|---|---|
| 1st Bracket | €0 – €28,000 | 23% |
| 2nd Bracket | €28,001 – €50,000 | 35% |
| 3rd Bracket | Over €50,000 | 43% |
Italian Deductions and No-Tax Area
- Employees benefit from a no-tax area (area di non-tassabilità) of approximately €8,500 of income effectively tax-free thanks to a deduction that offsets the 23% rate on the first portion of income.
- Additional deductions exist for dependent family members, mortgage interest, medical expenses, education costs, and more.
- Regional (addizionale regionale) and municipal (addizionale comunale) surcharges add between roughly 1.23% and 3.33% (regional) and 0% to 0.9% (municipal) on top of IRPEF, depending on where you live. In cities like Rome or Milan, these surcharges can meaningfully increase the overall tax burden.

Italian Social Security Contributions
Employees in Italy pay social security contributions (INPS) at approximately 9.19% of gross salary (up to a ceiling of around €119,650 for 2025). Employers contribute a far larger share—roughly 30%–32%—but, as in the UK, this doesn't directly reduce the employee's gross-to-net calculation in the same way.
United Kingdom vs Italy: Side-by-Side Rate Comparison
Comparing the two systems at a glance makes it easier to spot the structural differences.
| Feature | United Kingdom (2025/2026) | Italy (2025) |
|---|---|---|
| Top Marginal Rate | 45% (over £125,140) | 43% (over €50,000) + regional/municipal surcharges |
| Effective Top Rate (incl. surcharges) | 45% (+ 2% NIC) = ~47% | 43% + ~2–4% surcharges = ~45–47% |
| Tax-Free Allowance | £12,570 (~€14,700*) | ~€8,500 effective no-tax area |
| Lowest Positive Rate | 20% | 23% |
| Employee Social Security | 8% / 2% (NIC) | ~9.19% (INPS) |
| Number of Brackets | 3 taxable bands | 3 brackets |
*Currency conversion approximate at €1.17 per £1.
Quick takeaway: The UK's larger tax-free allowance and lower starting rate (20% vs 23%) generally benefit lower and middle-income earners. Italy's brackets kick in harder at the bottom but the top marginal rate of 43% is slightly lower than the UK's 45%. However, Italian regional and municipal surcharges can erode that advantage.
Practical Examples: Which Country Has Lower Income Tax?
Numbers tell the real story. Below we compare the approximate income tax plus employee social contributions for three salary levels. We assume a single employee with no dependents, standard deductions only, and residency in the respective country. For Italy we assume average regional/municipal surcharges of roughly 2.5% combined.
Example 1: Modest Salary – £30,000 / €35,100
United Kingdom:
- Income tax: (£30,000 − £12,570) × 20% = £3,486
- NICs: (£30,000 − £12,570) × 8% = £1,394
- Total deductions: £4,880 (~16.3% effective rate)
Italy (€35,100):
- IRPEF: €28,000 × 23% + €7,100 × 35% = €6,440 + €2,485 = €8,925, minus employee deduction (~€1,200) ≈ €7,725
- Regional/municipal surcharges: ~€878
- INPS: €35,100 × 9.19% ≈ €3,226
- Total deductions: ~€11,829 (~33.7% effective rate)
Winner at this level: United Kingdom by a wide margin. The generous Personal Allowance and 20% basic rate keep the UK burden much lower.
Example 2: Mid-Level Salary – £55,000 / €64,350
United Kingdom:
- Income tax: (£50,270 − £12,570) × 20% + (£55,000 − £50,270) × 40% = £7,540 + £1,892 = £9,432
- NICs: (£50,270 − £12,570) × 8% + (£55,000 − £50,270) × 2% = £3,016 + £95 = £3,111
- Total deductions: £12,543 (~22.8%)
Italy (€64,350):
- IRPEF: €28,000 × 23% + €22,000 × 35% + €14,350 × 43% = €6,440 + €7,700 + €6,171 = €20,311, minus reduced deduction (~€600) ≈ €19,711
- Surcharges: ~€1,609
- INPS: €64,350 × 9.19% ≈ €5,914
- Total deductions: ~€27,234 (~42.3%)
Winner: United Kingdom, again decisively. The combination of the higher tax-free threshold and lower basic rate means the UK employee takes home considerably more.
Example 3: High Salary – £120,000 / €140,400
United Kingdom:
- Personal Allowance is reduced to £2,860 (tapered withdrawal above £100,000)
- Income tax calculation: complex due to taper; approximately £40,100
- NICs: approximately £4,514
- Total deductions: ~£44,614 (~37.2%)
Italy (€140,400):
- IRPEF: €6,440 + €7,700 + (€90,400 × 43%) = €6,440 + €7,700 + €38,872 = €53,012, minus minimal deduction ≈ €52,700
- Surcharges: ~€3,510
- INPS: €140,400 × 9.19% (capped) ≈ €10,994
- Total deductions: ~€67,204 (~47.9%)
Winner: United Kingdom. Even at high earnings where the UK's 45% and NIC taper bite, the Italian combination of IRPEF, surcharges, and INPS still exceeds the UK burden.
These examples clearly show that the United Kingdom generally has lower income tax than Italy across virtually all income levels, primarily due to the larger tax-free allowance and lower starting rate.
Special Regimes and Expat Considerations
Headline rates don't always tell the full story. Both countries offer incentives that can dramatically alter the comparison.
Italy's Impatriate Tax Regime (Regime Impatriati)
Italy has historically attracted foreign talent with its impatriate regime, which allows qualifying individuals who transfer tax residence to Italy to pay income tax on only 50% (or in some cases 30%) of their employment income for a period of five years (extendable). Recent legislative changes for 2025 have tightened eligibility requirements and reduced the exemption to 50% for new applicants, with a cap of €600,000 of qualifying income.
- Who qualifies? Workers who have not been Italian tax residents for at least the two (or three, under new rules) preceding years and commit to residing in Italy for at least four years.
- Impact: An expat earning €100,000 could effectively pay IRPEF on only €50,000, dramatically lowering the effective rate.
Italy's Flat Tax for New Residents
High-net-worth individuals can opt for Italy's flat tax regime for new residents (regime forfettario per neo-residenti), paying a €200,000 per year lump sum on all foreign-sourced income, regardless of amount. This is extraordinarily attractive for wealthy individuals with significant overseas investment income.
UK: Non-Domicile Changes (2025/2026)
The UK's longstanding non-domicile (non-dom) regime—which allowed qualifying residents to avoid UK tax on foreign income and gains by not remitting them to the UK—was abolished from 6 April 2025. It has been replaced with a four-year Foreign Income and Gains (FIG) regime for new arrivals. Under the new rules:
- Individuals who become UK tax resident after a period of ten consecutive years of non-residence can elect to exclude foreign income and gains from UK tax for their first four tax years of residence.
- After four years, worldwide income is fully taxable.
This is more restrictive than the old non-dom regime but still offers short-term relief for incoming expats.
Double Taxation Treaty
The UK and Italy have a comprehensive double taxation agreement (DTA) that prevents the same income from being taxed twice. Key provisions include:
- Employment income is generally taxed in the country where the work is performed.
- Pensions are typically taxed in the country of residence (with some exceptions for government pensions).
- Dividends, interest, and royalties are subject to reduced withholding rates.
If you're moving between the two countries, understanding the DTA is critical for avoiding unexpected liabilities.
Common Mistakes and Misconceptions
When making a United Kingdom Italy income tax comparison, people frequently fall into these traps:
- Ignoring social security contributions. Italy's INPS employee rate (~9.19%) is higher than the UK's NIC rates for most earners. Excluding these paints an incomplete picture.
- Forgetting Italian regional and municipal surcharges. IRPEF alone doesn't represent the full Italian tax burden. Add 2–4% for local surcharges.
- Assuming the UK's Personal Allowance applies to everyone. High earners above £100,000 lose the allowance, and non-residents may not be entitled to it depending on their nationality and treaty rights.
- Overlooking Italy's special regimes. An expat eligible for the impatriate regime could pay less total tax in Italy than in the UK, reversing the general comparison.
- Comparing headline top rates only. Italy's 43% looks lower than the UK's 45%, but surcharges and INPS push Italy's effective top marginal rate above the UK's in most cases.
Frequently Asked Questions
Which country has lower income tax, the UK or Italy?
For most salary levels, the United Kingdom has lower income tax than Italy when you account for IRPEF, regional/municipal surcharges, and social security contributions. The UK's generous Personal Allowance (£12,570) and 20% basic rate provide a significant advantage at low-to-mid incomes.
Is Italy's flat tax regime better than living in the UK for wealthy individuals?
Potentially, yes. Italy's €200,000 lump-sum flat tax on all foreign-sourced income can be extremely advantageous for high-net-worth individuals with substantial overseas earnings. The UK's new FIG regime offers only four years of foreign income relief.
Do I pay tax in both countries if I move from the UK to Italy?
The UK-Italy double taxation treaty ensures you won't be taxed twice on the same income. However, you may need to file returns in both countries during a transition year, and some income types may be taxable in the source country. Professional advice is strongly recommended.
