What this calculator covers

Income Tax

IOM ITIP

10% on the first £6,500 of taxable income, then 21% above. Personal allowance of £17,000 (2026/27) applied before any tax. High earners above £100,000 see their allowance tapered at £1 per £2 over the threshold — reaching zero at £134,000.

Social Security

NI Contributions

Employee Class 1 NI deducted above the primary threshold (£9,152/year for 2026/27). Employer NI shown separately as an additional business cost above the secondary threshold — important for understanding the true cost of employment.

Pension & Tax Code

Accurate deductions

Enter your ITIP tax code to apply your actual personal allowance. Salary sacrifice pension reduces both your tax and NI base. Personal contributions reduce taxable income only. Employer pension shown as a separate business cost.
