Adjusted Net Income is the figure these tax thresholds actually use
When a UK tax rule mentions £60,000, £80,000 or £100,000, it almost never means the salary on your contract. It means your Adjusted Net Income (ANI) — your total taxable income after qualifying pension contributions and Gift Aid have been taken off.
Get that one figure right and the rest falls into place. The High Income Child Benefit Charge, the £100,000 Personal Allowance taper and the Tax-Free Childcare limit are all measured against your ANI, not your headline pay. Bonuses, taxable benefits and savings or dividend income push it up; pension contributions and Gift Aid bring it back down.
Worked examples
Two people on almost identical salaries can land on opposite sides of a threshold. These quick scenarios show how that happens, and why ANI is the figure doing the deciding.
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.
In practice: 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.
The lever: 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.
Easy to miss: 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.
Worth remembering: 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: a £90,000 salary plus a £10,000 bonus is £100,000
- Taxable benefits: private medical cover adds its taxable value
- Other taxable income such as savings interest or dividends: £1,500 of dividends is included
What can reduce ANI
- Qualifying gross pension contributions: £5,000 gross reduces ANI by £5,000
- Grossed-up Gift Aid donations: £80 donated counts as £100 off
- Checking the full income picture rather than salary alone: salary is the starting point, not the answer
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
What is adjusted net income?
Adjusted net income is your total taxable income for the year — salary, bonus, taxable benefits and income such as savings interest or dividends — minus a few specific reliefs, mainly grossed-up pension contributions and Gift Aid. It is the figure HMRC uses for several income thresholds.
Is adjusted net income the same as my salary?
No. Salary is usually the starting point, but adjusted net income can sit above or below it once other taxable income and qualifying reliefs are taken into account.
Is adjusted net income before or after tax?
It is based on your taxable income before your Personal Allowance is applied, then reduced by qualifying reliefs. It is not your take-home pay after tax.
Do pension contributions reduce adjusted net income?
Yes. Qualifying gross pension contributions come off your adjusted net income, which can sometimes move you back below a threshold such as £60,000 or £100,000.
Do dividends and savings interest count towards adjusted net income?
They can. Adjusted net income is based on total taxable income, which can include taxable savings interest and dividends on top of your salary.
Why does adjusted net income matter so much?
Because the High Income Child Benefit Charge, the £100,000 Personal Allowance taper and the Tax-Free Childcare limit are all measured against adjusted net income, not your headline salary.
