What happens if your income exceeds £100K 2023-24?

If you earn over £100,000 in any tax year your personal allowance is gradually reduced by £1 for every £2 of adjusted net income over £100,000 irrespective of age. This means that any taxable receipt that takes your income over £100,000 will result in a reduction in personal tax allowances. Accordingly, your personal Income Tax allowance would be reduced to zero if your adjusted net income is £125,140 or above.

Your adjusted net income is your total taxable income before any personal allowances, less certain tax reliefs such as trading losses and certain charitable donations and pension contributions.

For the current tax year, if your adjusted net income is likely to fall between £100,000 and £125,140 you would pay an effective marginal rate of tax of 60% as your £12,570 tax-free personal allowance is gradually withdrawn.

If your income sits within this band, you should consider planning opportunities available to avoid this personal allowance trap by reducing your income below £100,000. This can include giving gifts to charity, increasing pension contributions and participating in certain investment schemes.

A higher rate or additional rate taxpayer who wanted to reduce their tax bill could make a gift to charity in the current tax year and elect to carry back the contribution to 2022-23. A request to carry back the donation must be made before or at the same time as the 2022-23 self-assessment return is completed i.e., by 31 January 2024.
