Gibraltar Self-Employed Net Income Calculator
Calculate sole trader net income in Gibraltar after income tax (GIBS or ABS) and self-employed social insurance contributions, with allowance stacking explained.
What a Gibraltar sole trader keeps after tax and social insurance
Self-employed sole traders in Gibraltar are taxed on the same income tax rules as employees — the lower of ABS (personal allowance of £3,455, then 14%/17%/39% bands) or GIBS — but pay social insurance at a different rate and without an employer contribution alongside it.
For 2026/27, self-employed social insurance is 20% of earnings, roughly double the employee rate, reflecting that there's no separate employer-side contribution being paid on your behalf. This calculator applies both the income tax rules and the self-employed social insurance rules to show what you actually keep from your trading income.
What's included in this calculation
- Income tax under the lower of ABS (£3,455 allowance, then 14%/17%/39%) or GIBS
- Self-employed social insurance at 20% of earnings, with a minimum annual contribution of £1,583.40 and a maximum of £2,923.83
- No employer-side social insurance contribution to account for, unlike an employee
- The same personal allowance and tax bands apply as they would to an employee earning the same gross amount
