### How Taxable Income Is Calculated

Taxable income is your gross income from all sources (employment, self-employment, property, investments) minus your personal allowance.

Example: An employed individual earning £40,000 gross: - Gross income: £40,000 - Less personal allowance: £14,500 - Taxable income: £25,500

Income tax calculation: - 10% on first £6,500 = £650 - 20% on remaining £19,000 = £3,800 - Total income tax: £4,450

Effective overall rate on gross income: 11.1% (£4,450 / £40,000)

### Comparison to UK Income Tax on the Same £40,000

UK calculation: - Gross income: £40,000 - Less personal allowance: £12,570 - Taxable income: £27,430 - UK basic rate (20%) on £27,430 = £5,486 - Effective rate on gross: 13.7%

The Isle of Man resident saves £1,036 per year on the same salary — a meaningful but not enormous saving at this income level. The saving grows significantly at higher incomes.

### High Income Example: £150,000

Isle of Man: - Less personal allowance: £14,500 - Taxable income: £135,500 - 10% on first £6,500 = £650 - 20% on remaining £129,000 = £25,800 - Total tax: £26,450 - Effective rate: 17.6%

UK: - Personal allowance tapered to zero above £100,000 (lost £1 for every £2 above £100,000) - £27,430 at 20%, significant income at 40%, and income above £125,140 at 45% - Total income tax approximately: £54,430 - Effective rate: approximately 36.3%

The Isle of Man resident saves approximately £27,980 per year on a £150,000 income — just in income tax before considering NIC savings.

### Married Couple and Civil Partner Elections

Married couples and civil partners resident in the Isle of Man may elect for:

Separate assessment: Each partner is assessed independently on their own income. Both receive their full personal allowance of £14,500. This is the default.

Joint assessment: Income is combined and allocated between partners to minimise total tax liability. Generally beneficial where one partner has income below their personal allowance and the other earns above the basic rate band.

Example joint election: Partner A earns £60,000, Partner B earns £8,000. - Separately: Partner A pays approximately £8,700 tax; Partner B pays zero (income below allowance) - Jointly: No material difference in this case as both personal allowances are already in use

Joint election benefits where one partner has no or very little income, allowing transfer of allowance or income between spouses.

### What Income Is Included?

All sources of income are included in the Isle of Man income tax computation: - Employment income (salary, wages, bonuses, benefits in kind) - Pensions - Self-employment profits - Rental income from Isle of Man properties (at 20%) - Dividends from companies (no separate dividend rate in IoM — included in total income) - Interest income - Overseas income received by Manx residents (subject to relief under DTAs)

### Self-Employment: ITIP and National Insurance

Self-employed individuals pay income tax via self-assessment (Form IT1, due 6 October). They also pay: - Class 2 NICs: flat-rate weekly contribution - Class 4 NICs: 8% on profits between lower and upper limits; 1% above

Directors who take a salary through the company ITIP system pay income tax monthly via ITIP (the Manx PAYE equivalent), with a year-end reconciliation.

### Manx Tax Return Deadline

Personal income tax returns (Form IT1) are due by 6 October each year — 6 months after the tax year ends on 5 April. This is significantly earlier in the tax calendar than the UK's 31 January self-assessment deadline.
