What is adjusted net income?
Adjusted net income is the figure HMRC uses for the income limits that matter most to families: the £100,000 limit for funded childcare and Tax-Free Childcare, the Personal Allowance taper (the 60% tax trap) and the Child Benefit charge. It's worked out for each person separately.
Start with your taxable income
- Salary and bonuses, after any salary sacrifice
- Taxable benefits, such as private medical insurance or a company car
- Savings interest and dividends
- Other taxable income, such as self-employment or rent
Then take off
- Pension contributions taken from pay before tax (net pay)
- Personal pension contributions, grossed up: what you pay plus 25%
- Gift Aid donations, grossed up the same way
- Trading losses, if you have them
An example
A parent earns £105,000, gets £1,000 of bank interest and pays £4,000 into a personal pension. The pension counts as £5,000 gross, so adjusted net income is £105,000 + £1,000 − £5,000 = £101,000. That's still over £100,000, so the family would lose funded hours and Tax-Free Childcare. Paying in another £800 (£1,000 gross) would bring it to £100,000.
