DON’T LOSE YOUR PERSONAL ALLOWANCE…
For every £2 that your adjusted net income exceeds £100,000, the £11,850 personal allowance is reduced by £1. This results in an effective personal income tax rate of 60%.
Pension contributions and Gift Aid can help to reduce adjusted net income and save tax.
The restriction applies between £100,000 and £123,700 adjusted net income.
Another way that you could avoid this trap would be to agree with your employer to sacrifice some of your salary in exchange for a tax-free benefit in kind.
These rules changed from 6 April 2017 but employer pension contributions, bicycles, and employer provided childcare would continue to be tax effective.
