Adjusted Net Income (ANI) is the HMRC figure behind these threshold checks
Adjusted Net Income (ANI) starts with your taxable income, then takes off certain reliefs such as qualifying pension contributions and Gift Aid. It is the figure HMRC uses for rules such as the High Income Child Benefit Charge, Tax-Free Childcare and the £100,000 Personal Allowance taper.
Worked examples
These examples are designed to make ANI easier to picture in real life. They show why two people with similar salaries can still land on different threshold outcomes.
Salary £95,000, no other adjustments
ANI is usually close to £95,000. If there are no extra taxable amounts or qualifying reliefs, salary can be a reasonable first estimate.
Why it matters: sometimes the quick answer really is close to the headline salary.
Salary £103,000, £4,000 gross pension
ANI can fall to about £99,000. A qualifying gross pension contribution can move someone back below the £100,000 Personal Allowance taper line.
Why it matters: the right pension figure can change the threshold outcome completely.
Salary £62,000, £800 Gift Aid donation
ANI can fall by about £1,000. HMRC uses the grossed-up value of a Gift Aid donation when working out ANI.
Why it matters: many readers understate Gift Aid’s effect because they use the cash amount only.
Salary £99,000, bonus and benefits
ANI can still end up above £100,000. A bonus, taxable benefits or extra investment income can push ANI above a line even where base salary sits below it.
Why it matters: ANI is a tax number, not just an employment-contract number.
What ANI is usually used for
Most readers are not calculating ANI for fun. They are trying to answer a threshold question quickly and avoid using the wrong number.
ANI is the number behind several family and higher-income rules
The biggest practical uses are checking the Child Benefit charge, the £100,000 Personal Allowance taper and childcare rules that use adjusted net income. That is why this page focuses on the ANI figure first, then points you to the next decision page.
Use ANI when a rule mentions a threshold, not salary alone
If a page asks whether you are above £60,000, £80,000 or £100,000, the right question is usually whether your adjusted net income is above that line after reliefs.
What often counts in
- Employment income and bonuses
- Taxable benefits
- Other taxable income such as savings interest or dividends
What can reduce ANI
- Qualifying gross pension contributions
- Grossed-up Gift Aid donations
- Checking the full income picture rather than salary alone
What people often miss
These are the mistakes that usually lead to the wrong threshold answer, even when the reader already knows roughly how ANI works.
Using net pay or take-home pay
ANI is not worked out from the amount you keep after tax. It is based on taxable income before Personal Allowances, then reduced by the reliefs HMRC says count.
Ignoring benefits, bonuses or other income
People often remember salary and forget the pieces that actually move them over a threshold. A small extra amount can be enough to change the result.
Once you have ANI, move to the rule page that uses it
That usually means the Child Benefit charge page, the £100k tax-trap page or the childcare threshold page. This calculator is the number-building step before those decisions.

Questions people usually ask
Is Adjusted Net Income (ANI) the same as salary?
No. Salary may be the starting point, but ANI can move up or down once other taxable income and qualifying reliefs are included.
Do pension contributions reduce ANI?
Yes. Qualifying gross pension contributions can reduce ANI and sometimes change a threshold outcome completely.
Why does ANI matter so much?
Because several UK tax and family-support rules use Adjusted Net Income (ANI) rather than salary, including the High Income Child Benefit Charge (HICBC), the £100,000 Personal Allowance taper and the Tax-Free Childcare income limit.
