How does Isle of Man tax compare to UK tax?

## Isle of Man vs UK Tax Comparison (2025/26)

### Corporate Income Tax

| | Isle of Man | United Kingdom | |--|--|--| | Standard rate | 0% | 25% (profits above £250,000) | | Lower rate | N/A | 19% (profits up to £50,000) | | Banking income | 10% | 25% + 3% surcharge = 28% | | Land/property income | 20% | 25% |

For most trading and investment companies, the Isle of Man's 0% corporate tax rate represents an enormous difference compared to the UK's 25% main rate. A company with £500,000 of annual profit pays £0 in Manx corporate tax versus £125,000 UK corporation tax.

### Capital Gains Tax

| | Isle of Man | United Kingdom | |--|--|--| | Individual CGT | 0% | 18% (basic rate) / 24% (higher rate) on property; 10%/20% on other assets | | Company CGT | 0% (within 0% corporate tax) | 25% corporation tax on chargeable gains |

No capital gains tax exists in the Isle of Man for individuals or companies. UK individuals may face CGT of up to 24% on property gains and 20% on other gains at the higher rate.

### Inheritance Tax / Wealth Transfer

| | Isle of Man | United Kingdom | |--|--|--| | Inheritance Tax | 0% — no IHT | 40% on estates above £325,000 threshold | | Residence nil-rate band | N/A | £175,000 additional allowance for passing on a family home |

### Income Tax

| | Isle of Man | United Kingdom | |--|--|--| | Personal allowance | £14,500 | £12,570 | | Basic rate | 10% (on first £6,500 of taxable income) | 20% | | Higher rate | 20% (on all income above basic band) | 40% (on income £50,270–£125,140) | | Additional rate | None | 45% (on income above £125,140) | | Dividend tax (basic rate) | 10%/20% via normal income tax bands | 8.75% (dividend ordinary rate) | | Dividend tax (higher rate) | 20% max | 33.75% | | Dividend allowance | None — but low rate applies | £500 (2024/25) |

The difference for high earners is stark. A UK additional-rate taxpayer faces a combined marginal rate of income tax + NI of over 47% (45% income tax + 2% NI above UEL). An Isle of Man resident in an equivalent position pays a maximum 20% income tax plus Manx NIC rates.

### National Insurance

| | Isle of Man | United Kingdom | |--|--|--| | Employee rate (main rate) | 11% (between £145–£833/week) | 8% (post-April 2024 cut) | | Employee rate (upper) | 1% (above £833/week) | 2% | | Employer rate | 13.6% | 13.8% |

Interestingly, Isle of Man employee NIC rates (11%) are higher than current UK rates (8% after the April 2024 reduction), though the employer rate is very similar.

### VAT

| | Isle of Man | United Kingdom | |--|--|--| | Standard rate | 20% | 20% | | Reduced rate | 5% | 5% | | Zero rate | 0% | 0% | | Registration threshold | £90,000 | £90,000 | | Administration | IoM Treasury | HMRC |

VAT is effectively identical — same rates, same rules, same threshold — reflecting the single VAT area between the IoM and UK.

### Stamp Duty

| | Isle of Man | United Kingdom | |--|--|--| | SDLT on property | Manx Stamp Duty applies on IoM property | SDLT up to 12% on UK residential property | | Stamp duty on share transfers | 0% | 0.5% SDRT |

### Overall Assessment

For a genuine Isle of Man resident or business operating on the island, the combined tax savings can be very substantial:

• A company earning £500,000 saves £125,000 per year in corporate tax alone
• A high-earning individual avoids the 40–45% income tax bands — paying 20% maximum
• No CGT on investments
• No IHT on estates passed to heirs

These advantages are lawful and available to individuals and businesses that genuinely relocate to and operate from the Isle of Man. They are not available to UK residents who simply incorporate a Manx company while remaining in the UK.
