What is adjusted net income?
Adjusted net income (ANI) is your total taxable income minus certain deductions — pension contributions, Gift Aid donations, and trading losses. It determines whether your personal allowance is reduced above £100,000 [VERIFY] and whether you owe the High Income Child Benefit Charge above £60,000[VERIFY]. Managing ANI is one of the highest-value tax planning opportunities for directors, high earners, and landlords. [VERIFY at gov.uk]
Why ANI matters — key thresholds [VERIFY]
| ANI threshold [VERIFY] | What triggers | Impact |
|---|---|---|
| Above £60,000 [VERIFY] | High Income Child Benefit Charge starts | 1% charge per £200 above £60k |
| Above £80,000 [VERIFY] | Full HICBC — all Child Benefit clawed back | Full Child Benefit repaid via tax |
| Above £100,000 [VERIFY] | Personal allowance taper begins | £1 allowance lost per £2 income — effective 60% rate |
| Above ~£125,140 [VERIFY] | Personal allowance fully withdrawn | No personal allowance — pay tax from £0 |

How to reduce adjusted net income
Employer pension contributions →
Paid by your limited company. Reduce company taxable profits AND come out before ANI is calculated. Most tax-efficient for director-shareholders. Subject to annual allowance. [VERIFY]
Personal pension contributions (SIPP) →
You pay into a SIPP. Basic rate relief added automatically. The gross contribution reduces ANI. Can restore personal allowance and avoid HICBC.
Gift Aid donations →
The gross value of Gift Aid donations reduces ANI. Must have paid enough tax to cover the basic rate relief claimed.
Salary/dividend optimisation →
For company directors: structuring salary to keep ANI below key thresholds. Works alongside pension contributions.
Adjusted net income — FAQs
What is adjusted net income?
Adjusted net income (ANI) is your total income from all sources minus certain deductions. It is used by HMRC to calculate: (1) whether your personal allowance is reduced (above £100,000 [VERIFY]); (2) whether you owe the High Income Child Benefit Charge (above £60,000 [VERIFY]); (3) whether your pension annual allowance is tapered (for very high earners). Reducing your ANI is one of the most important tax planning actions for high earners.
How is adjusted net income calculated?
Start with your total income: employment income, self-employment profit, rental income, investment income, pension income, and any other taxable income. Subtract: gross personal pension contributions (the amount before basic rate tax relief), Gift Aid donations (the gross amount), trading losses, certain employment expenses. The result is your adjusted net income. [VERIFY: HMRC's exact formula at gov.uk/guidance/adjusted-net-income]
Why does adjusted net income matter at £100,000?
The personal allowance tapers by £1 for every £2 of income above £100,000 [VERIFY]. By the time ANI reaches £125,140 [VERIFY], the personal allowance is completely withdrawn. This creates an effective 60% tax rate on income between £100,000 and £125,140 — one of the highest marginal rates in the UK tax system. Reducing ANI below £100,000 through pension contributions or Gift Aid restores the full personal allowance. [VERIFY: current figures at gov.uk/income-tax-rates]
What is the High Income Child Benefit Charge?
If either parent in a household has ANI above £60,000 [VERIFY], a tax charge applies that claws back Child Benefit. Above £80,000 [VERIFY], the full Child Benefit is clawed back. The charge is calculated at 1% of the Child Benefit for every £200 of ANI above £60,000. Reducing ANI below £60,000 through pension contributions avoids the charge entirely.

How can I reduce my adjusted net income?
The most common and effective methods: (1) Employer pension contributions — these come out before ANI is calculated and reduce the company's corporation tax; (2) Personal pension contributions — these reduce ANI and attract basic rate relief automatically, plus the ANI reduction restores the personal allowance; (3) Gift Aid charitable donations — the gross donation reduces ANI; (4) For business owners: salary/dividend optimisation to keep ANI below key thresholds.
