Current Rate (6 April to 5 April)
10% on first £6,500 of taxable income; 20% above. Personal allowance £14,500.
Example
A single Manx resident earning £40,000 salary has taxable income of £25,500 (£40,000 minus £14,500 allowance). They pay £650 (10% on £6,500) + £3,800 (20% on £19,000) = £4,450 income tax.
How Income Tax (Isle of Man) works in Isle of Man
The Isle of Man's income tax system is administered by the Assessor of Income Tax and differs materially from the UK system. The Manx rates are significantly lower than UK equivalents, with no higher rate band equivalent to the UK's 40% rate.
Key 2025/26 figures: - Personal allowance: £14,500 (significantly higher than UK's £12,570) - Basic rate: 10% on first £6,500 of taxable income - Higher rate: 20% on income above £6,500 of taxable income - No additional rate equivalent to UK 45% — the 20% rate applies to all income above the basic band
Joint taxation: Married couples and civil partners resident in the Isle of Man may elect for joint assessment or separate assessment. Joint assessment allows each partner to claim their full personal allowance and may reduce overall liability where one partner earns less.
Dividend income: Isle of Man resident individuals receiving dividends from Manx companies have already had corporate tax paid on profits (at 0%). The Isle of Man does not apply a separate dividend tax rate — dividends are treated as ordinary income subject to the 10%/20% bands (after allowances). This contrasts significantly with UK rules where dividends have their own tax rates and the dividend allowance.
Self-assessment: The IoM operates self-assessment for income tax, with a return (Form IT1) due 6 months after the tax year end (i.e., 5 October). Online filing via the Government's MyGov.IM service is available.
PAYE: Employers deduct income tax and National Insurance under the Isle of Man's ITIP (Income Tax Instalment Payments) system, equivalent to UK PAYE.
Non-residents: Non-residents pay Isle of Man income tax only on income with an Isle of Man source (employment in the IoM, IoM-based property income, etc.).
