Your total taxable income minus certain reliefs, used to determine allowance eligibility.
Adjusted Net Income is your total taxable income minus certain tax reliefs, such as pension contributions (paid gross) and Gift Aid donations. HMRC uses this figure to determine whether your Personal Allowance should be reduced (the taper above £100,000) and whether you need to pay the High Income Child Benefit Charge. It is a critical number for high earners because it determines access to key tax allowances.
