Whether you're an expat weighing a move between London and Rome, a remote worker choosing your tax residence, or simply curious about how two of Europe's largest economies stack up fiscally, understanding the United Kingdom vs Italy income tax landscape is essential. In this comprehensive income tax comparison for 2025/2026, we break down rates, brackets, allowances, and real-world scenarios so you can make informed financial decisions.
Both the UK and Italy operate progressive income tax systems, but they differ significantly in structure, rates, and the additional levies that affect your take-home pay. This tax comparison United Kingdom Italy guide will walk you through everything you need to know.
How Income Tax Works: UK vs Italy at a Glance
Before diving into the details, here's a high-level overview of how each country approaches personal income tax:
| Feature | United Kingdom | Italy |
|---|---|---|
| Tax Year | 6 April 2025 – 5 April 2026 | 1 January 2025 – 31 December 2025 |
| Currency | GBP (£) | EUR (€) |
| Tax Authority | HMRC | Agenzia delle Entrate |
| Progressive Brackets | 3 main rates (+ additional) | 4 brackets |
| Top Marginal Rate | 45% | 43% |
| Personal Allowance | £12,570 | Varies (up to €1,955 credit) |
| Local/Regional Tax | None on income (Council Tax is separate) | Yes – regional & municipal surcharges |
As the table shows, while both systems are progressive, Italy layers on regional and municipal taxes that can significantly increase the effective rate. The UK system is arguably simpler in structure but has its own complexities, particularly around the tapering of the personal allowance for high earners.
UK Income Tax Rates and Brackets for 2025/2026
The United Kingdom's income tax system for the 2025/2026 tax year (6 April 2025 to 5 April 2026) applies to residents on their worldwide income. Non-residents are generally taxed only on UK-sourced income.
Tax-Free Personal Allowance
Every UK taxpayer is entitled to a personal allowance of £12,570, meaning the first £12,570 of annual income is tax-free. However, this allowance is gradually reduced by £1 for every £2 of income above £100,000, meaning it is completely eliminated once income reaches £125,140.
Income Tax Bands
| Band | Taxable Income | 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% |
Note for Scotland: Scottish taxpayers have a different rate structure with six bands (including a starter rate of 19%, an intermediate rate of 21%, and an advanced rate of 45% before the top rate of 48%). This guide focuses on the rates for England, Wales, and Northern Ireland.
National Insurance Contributions (NICs)
While not technically income tax, National Insurance Contributions are a mandatory payroll deduction that effectively increases the tax burden:
- Employee NIC (Class 1): 8% on earnings between £12,570 and £50,270; 2% on earnings above £50,270
- Employer NIC: 15% on earnings above £5,000 (paid by the employer)
When you combine income tax and employee NICs, a UK basic-rate taxpayer faces a combined marginal rate of 28% (20% tax + 8% NIC), while a higher-rate taxpayer faces 42% (40% + 2%).

Italy Income Tax Rates and Brackets for 2025
Italy's personal income tax — known as IRPEF (Imposta sul Reddito delle Persone Fisiche) — applies to the worldwide income of Italian tax residents. Non-residents are taxed only on Italian-sourced income.
IRPEF Tax Brackets
For the 2025 tax year, Italy applies the following national income tax rates:
| Bracket | Taxable Income (EUR) | Rate |
|---|---|---|
| 1st Bracket | €0 – €28,000 | 23% |
| 2nd Bracket | €28,001 – €50,000 | 35% |
| 3rd Bracket | €50,001 – €100,000 | 43% |
| 4th Bracket | Over €100,000 | 43% |
Italy consolidated its tax brackets in recent years. The third and fourth brackets share the same 43% rate, but the structure remains as shown above following the 2025 fiscal provisions.
Tax Credits Instead of a Personal Allowance
Unlike the UK, Italy does not have a straightforward personal allowance. Instead, it uses a system of tax credits (detrazioni) that reduce your tax liability:
- Employment income credit: Up to approximately €1,955 for employees, gradually decreasing as income rises and phasing out entirely above €50,000.
- Self-employment income credit: A smaller credit is available for self-employed individuals.
- Pension income credit: Retirees receive a separate, slightly different credit.
These credits effectively create a tax-free threshold of roughly €8,500 for employees, though the exact amount depends on individual circumstances.
Regional and Municipal Surcharges
A critical difference in the tax comparison United Kingdom Italy is that Italian taxpayers must also pay:
- Regional surcharge (addizionale regionale): Ranges from 1.23% to 3.33% depending on the region. For example, Lazio (Rome) charges up to 3.33%, while some regions charge the minimum 1.23%.
- Municipal surcharge (addizionale comunale): Ranges from 0% to 0.9% depending on the municipality.
These surcharges are calculated on the same taxable income and can add 2% to 4% on top of the national IRPEF rates, significantly increasing the effective tax burden.

Side-by-Side Comparison: Practical Tax Examples
Let's compare the income tax burden in both countries using practical salary examples. For Italy, we'll assume the taxpayer lives in Rome (Lazio region, with a combined regional/municipal surcharge of approximately 3.5%). For the UK, we'll use the England/Wales rates.
Example 1: Moderate Salary – £40,000 / €47,000
Assumptions: Single employee, no dependents, standard deductions/allowances.
United Kingdom (£40,000):
- Personal allowance: £12,570 at 0% = £0
- Basic rate: £27,430 at 20% = £5,486
- Total income tax: £5,486
- Employee NIC: ~£2,194
- Combined tax + NIC: ~£7,680
- Effective rate (tax only): ~13.7%
- Effective rate (tax + NIC): ~19.2%
Italy (€47,000):
- First €28,000 at 23% = €6,440
- Next €19,000 at 35% = €6,650
- Gross IRPEF: €13,090
- Less employment tax credit: ~€600 (reduced at this income level)
- Net IRPEF: ~€12,490
- Regional/municipal surcharge (~3.5%): ~€1,645
- Total income tax: ~€14,135
- Effective rate: ~30.1%
At this moderate income level, the Italian tax burden is notably higher, even before considering Italy's social security contributions (approximately 9.19% for employees).
Example 2: Higher Salary – £80,000 / €94,000
United Kingdom (£80,000):
- Personal allowance: £12,570 at 0%
- Basic rate: £37,700 at 20% = £7,540
- Higher rate: £29,730 at 40% = £11,892
- Total income tax: £19,432
- Employee NIC: ~£4,244
- Combined tax + NIC: ~£23,676
- Effective rate (tax only): ~24.3%
- Effective rate (tax + NIC): ~29.6%
Italy (€94,000):
- First €28,000 at 23% = €6,440
- Next €22,000 at 35% = €7,700
- Next €44,000 at 43% = €18,920
- Gross IRPEF: €33,060
- Less employment tax credit: €0 (phased out above €50,000)
- Regional/municipal surcharge (~3.5%): ~€3,290
- Total income tax: ~€36,350
- Effective rate: ~38.7%
At higher income levels, the gap widens considerably. The Italian taxpayer faces an effective rate nearly 15 percentage points higher than their UK counterpart (when comparing tax only). Even when UK NICs are included, Italy remains significantly more expensive.
Example 3: High Earner – £150,000 / €176,000
United Kingdom (£150,000):
- Personal allowance: £0 (tapered away above £125,140)
- Basic rate: £37,700 at 20% = £7,540
- Higher rate: £87,430 at 40% = £34,972
- Additional rate: £24,870 at 45% = £11,192
- Total income tax: £53,704
- Effective rate (tax only): ~35.8%
Italy (€176,000):
- First €28,000 at 23% = €6,440
- Next €22,000 at 35% = €7,700
- Remaining €126,000 at 43% = €54,180
- Gross IRPEF: €68,320
- Regional/municipal surcharge (~3.5%): ~€6,160
- Total income tax: ~€74,480
- Effective rate: ~42.3%
For high earners, Italy's income tax burden is approximately 6.5 percentage points higher than the UK's — a difference of roughly €11,500 (or ~£9,800) in absolute terms.
Key Differences Beyond the Tax Brackets
Social Security Contributions
Both countries levy social security contributions on top of income tax:
- UK: Employee National Insurance at 8%/2% (as described above)
- Italy: Employee social contributions of approximately 9.19% of gross salary (employer contributions are around 30%)
Italian social contributions are generally higher, which further increases the overall tax wedge.
Tax Deductions and Credits
Both countries offer deductions and credits, but the systems differ:
United Kingdom:
- Pension contributions receive tax relief at your marginal rate
- Marriage allowance (transferable £1,260 to a spouse)
- Limited deductions for work-related expenses
- Gift Aid donations receive tax relief
Italy:
- 19% tax credit on medical expenses exceeding €129
- 19% credit on mortgage interest (up to €4,000)
- Credits for dependent family members
- Various "bonus" deductions for home renovations (50%-65% over multiple years)
- Deduction for social security contributions
Italy's deduction system is more extensive but also more complex, often requiring detailed documentation.
Special Tax Regimes
Italy's Flat Tax for New Residents: Italy offers an attractive flat tax regime for high-net-worth individuals who transfer their tax residence to Italy. Under this scheme, qualifying individuals can pay a lump sum of €200,000 per year (€25,000 for each qualifying family member) on all foreign-sourced income, regardless of the amount. This can be extraordinarily beneficial for wealthy individuals.
Additionally, Italy has historically offered favorable tax regimes for workers and researchers relocating to Italy, though these programs have been modified for 2025 and now offer a 50% income tax exemption (down from 70%) for qualifying individuals who transfer their residence to Italy, subject to specific conditions and income caps.
United Kingdom: The UK's previous non-domicile ("non-dom") regime, which allowed certain residents to avoid UK tax on foreign income and gains not remitted to the UK, has been reformed from April 2025. A new Foreign Income and Gains (FIG) regime provides a four-year exemption for qualifying new arrivals, after which worldwide income is fully taxable.
Double Taxation Agreement
The UK and Italy have a comprehensive double taxation agreement (DTA) that prevents the same income from being taxed in both countries. Key provisions include:
- Employment income is generally taxed where the work is performed
- Pension income has specific rules depending on whether it's a government or private pension
- Dividends, interest, and royalties have reduced withholding tax rates
- Capital gains are generally taxed in the country of residence
If you have income in both countries, this treaty is critical to avoiding double taxation. You'll typically receive a foreign tax credit in your country of residence for taxes paid in the other country.
Filing Deadlines and Compliance
Understanding when and how to file is just as important as knowing the rates.
United Kingdom
- PAYE (Pay As You Earn): Most employees have tax deducted at source, and many do not need to file a return.
- Self-Assessment deadline: 31 January following the end of the tax year (e.g., 31 January 2027 for the 2025/2026 tax year) for online filing.
- Paper returns: Due by 31 October.
- Payment deadline: 31 January (with a possible second payment on account due 31 July).
Italy
- Modello 730 (simplified return for employees/pensioners): Due by 30 September 2026 for the 2025 tax year.
- Modello Redditi PF (comprehensive return): Due by 30 November 2026 for the 2025 tax year.
- Tax payments: First advance payment by 30 June, second advance by 30 November, and the balance by 30 June of the following year.
Italy's system is more complex, and many taxpayers rely on CAF (Centri di Assistenza Fiscale) — tax assistance centers — or professional accountants (commercialisti) to handle their returns.
Frequently Asked Questions
Which country has higher income tax, the UK or Italy?
Italy generally has a higher income tax burden than the United Kingdom at most income levels. When you factor in regional and municipal surcharges, Italian taxpayers can face effective rates 5-15 percentage points higher than their UK counterparts, depending on income level and region of residence.
Do I have to pay tax in both countries if I move from the UK to Italy?
Not on the same income, thanks to the UK-Italy double taxation agreement. However, you may have tax obligations in both countries during the year of transition, and you'll need to determine your tax residence status carefully. Income earned while resident in the UK is taxable there, and income earned while resident in Italy is taxable in Italy.
Is Italy's flat tax regime available to everyone?
No. The €200,000 lump-sum flat tax is available only to individuals who have not been Italian tax residents for at least nine of the previous ten tax years before transferring their residence to Italy. It applies only to foreign-sourced income; Italian-sourced income is taxed under normal IRPEF rules.
Are UK National Insurance Contributions comparable to Italian social security?
Both serve a similar purpose (funding state pensions, healthcare, and social benefits), but Italian employee social contributions (~9.19%) are higher than UK employee NICs (~8%/2%). Employer-side contributions are dramatically higher in Italy (~30%) compared to the UK (~15%).
