Income

Bonus is assumed to be a one-off annual payment made in a single month alongside your regular salary. Results may differ for weekly or four-weekly paid employees or those receiving regular variable pay.

Pension

⚠ Annual Allowance: pension contributions are capped at £60,000/year (2026/27) or 100% of earnings if lower. If you have triggered the Money Purchase Annual Allowance (MPAA) the limit falls to £10,000. We do not verify this — if in doubt seek independent financial advice.
