What is adjusted net income?

RIFT Roundup: 

• Total earnings minus tax-relieving extras: Adjusted Net Income (ANI) isn't what lands in your bank account - it's your total annual earnings (wages, overtime, site allowances, side hustles, bank interest) minus tax-relieving extras like pension payments and Gift Aid donations.

• Triggers child benefit tax traps: HMRC uses this figure to decide if you have to pay back Child Benefit; if your ANI passes £60,000, you start losing benefit money, and at £80,000, it's wiped out completely.

• Pensions reduce your ANI: Putting money into a pension lowers your ANI; because HMRC adds basic-rate tax relief back on top, paying £800 into a pension knocks a full £1,000 off your ANI calculation.

What does adjusted net income actually mean?

Adjusted net income is the figure HMRC uses after looking at your taxable income and then applying certain adjustments. 

A simple way to think about it is: 

• Total taxable income

• Minus certain tax reliefs and deductions

• Equals adjusted net income. 

It is worked out before your Personal Allowance is taken off. 

That last part matters. Your adjusted net income is not your final taxable income after allowances. It is the figure HMRC uses to decide whether certain allowances or charges apply in the first place. 

This is why two people with the same salary could have different adjusted net incomes. One might pay into a pension or make Gift Aid donations, while the other does not. Those details can change the final figure. 

"Adjusted Net Income sounds like dry tax jargon, but it directly hits your wallet. It's not your take-home pay - it's the official benchmark number HMRC uses to decide if you owe Child Benefit tax or if they should slash your tax-free allowance. The good news is that putting cash into a pension lowers this number, helping you protect your benefits." - Jason Scrivens-Waghorn (FCCA), RIFT Finance Director

Gross income vs adjusted net income

Gross income and adjusted net income are not the same thing. 

Your gross income is usually the total amount you earn before tax, National Insurance and other deductions. 

Adjusted net income is more specific. It starts with your total taxable income, then takes away certain reliefs and deductions recognised by HMRC. 

For example, your gross income might include your salary, rental income and savings interest. Your adjusted net income might be lower if you have made pension contributions or Gift Aid donations that qualify for relief. 

That difference can be important if you are close to a tax threshold. 

Why adjusted net income matters

Adjusted net income can affect how much tax you pay and whether certain charges apply. 

It is used for things like:

• checking whether your Personal Allowance is reduced

• working out the High Income Child Benefit Charge

• assessing certain tax reliefs and allowances

• understanding whether your tax code reflects your circumstances correctly 

This is where people can get caught out. 

You might look at your salary and assume you are comfortably below a threshold. But once other income is added, such as rental income, dividends or savings interest, your adjusted net income could be higher than expected.

The opposite can also happen. Pension contributions, Gift Aid and certain reliefs can bring the figure down. 

Adjusted net income and Personal Allowance

Most people in the UK get a tax-free Personal Allowance. 

• For the 2026/27 tax year, the standard Personal Allowance is £12,570.

• If your adjusted net income goes over £100,000, your Personal Allowance starts to reduce.

• For every £2 of adjusted net income above £100,000, you lose £1 of Personal Allowance.

• By the time your adjusted net income reaches £125,140, your Personal Allowance is usually gone completely. 

This creates what is often called the 60% tax trap, because income between £100,000 and £125,140 can be taxed very heavily once the lost allowance is factored in. 

If you are close to this threshold, it is worth understanding whether pension contributions, Gift Aid or other reliefs affect your adjusted net income.

Adjusted net income and Child Benefit

Adjusted net income is also used for the High Income Child Benefit Charge. 

From the 2024/25 tax year onwards, the charge starts when one partner has adjusted net income over £60,000. 

If one partner has adjusted net income of £80,000 or more, the full Child Benefit amount is usually clawed back through the charge. 

This applies to individuals, not household income. That means a household where one partner earns £65,000 and the other earns nothing may face the charge, while another household where both partners earn £55,000 may not. 

That can feel frustrating, but it is how the current system works. 

If you are claiming Child Benefit and your income is close to the threshold, adjusted net income is the figure to watch. 

What income counts towards adjusted net income?

HMRC includes taxable income from different sources when calculating adjusted net income. 

This can include:

• salary and wages

• bonuses and commission

• self-employed profits

• rental income

• savings interest

• dividends

• pension income

• some state benefits

• benefits in kind from work

• foreign income

• income from a trust 

This is why adjusted net income can catch people by surprise. It is not always just your main job that matters. 

If you have a side income, rent out a property, receive dividends or earn savings interest, those amounts can push your adjusted net income up. 

What can reduce adjusted net income?

Certain deductions and reliefs can reduce adjusted net income. 

Common examples include:

• pension contributions

• Gift Aid donations

• trading losses

• some property loss reliefs

• certain allowable deductions 

Pension contributions are especially important. If your pension provider has already given you basic-rate tax relief, HMRC may use the grossed-up amount when working out adjusted net income. For example, a £1,000 personal pension contribution may be treated as £1,250 for this purpose. 

Gift Aid works in a similar way. If you donate £100 to charity under Gift Aid, the grossed-up amount is £125. 

These details matter because they can bring your adjusted net income below important thresholds. 

Do work expenses reduced adjusted net income?

This depends on the type of expense and how it is claimed. 

Some allowable expenses can reduce the amount of income you pay tax on. This is particularly relevant if you have paid out of pocket for work costs that were necessary for your job and were not reimbursed by your employer. 

Common work-related costs may include:

• work travel

• mileage

• tools

• uniforms or protective clothing

• professional fees

• certain accommodation costs

• meals while travelling for work 

For PAYE workers, these claims can often result in tax relief rather than simply changing your adjusted net income in the same way as pension contributions or Gift Aid. 

The main point is this: if you are not claiming relief on costs you had to cover yourself, you could be paying more tax than necessary. 

How to calculate adjusted net income

You can work out adjusted net income by following a few steps. 

Step 1: Add up your taxable income 

Start with all taxable income, including:

• employment income

• self-employed profits

• rental income

• savings interest

• dividends

• pension income

• taxable benefits 

Step 2: Take off eligible reliefs 

Deduct reliefs such as:

• pension contributions paid gross

• certain trading losses

• qualifying property losses 

Step 3: Take off Gift Aid donations 

Use the grossed-up amount. 

For example, if you donate £80 through Gift Aid, the grossed-up amount is £100. 

Step 4: Take off pension contributions where basic-rate relief has already been given 

Again, use the grossed-up amount. 

For example, if you pay £800 into a personal pension and the pension provider claims £200 basic-rate relief, the grossed-up contribution is £1,000. 

Step 5: Check whether any amounts need adding back 

In some specific cases, certain deductions need adding back, such as some relief for payments to trade unions or police organisations. 

After those steps, the figure left is your adjusted net income. 

Example: adjusted net income calculation 

Let’s keep it simple. 

You have:

• salary: £68,000

• savings interest: £1,000

• rental income: £3,000 

Your total taxable income is £72,000. 

You also paid: 

• £2,000 into a personal pension

• £400 to charity through Gift Aid 

If both need grossing up:

• pension contribution becomes £2,500

• Gift Aid donation becomes £500 

Your adjusted net income would be: 

£72,000 
minus £2,500 pension contribution 
minus £500 Gift Aid 
= £69,000 adjusted net income. 

This is the figure HMRC would use when checking certain thresholds.

How Adjusted Net Income (ANI) Affects Your Tax & Benefits

Why young workers should understand net income

You do not need to earn six figures for adjusted net income to matter. 

It can become relevant if you:

• start a side hustle

• pick up freelance work

• receive bonuses or commission

• have more than one job

• start renting out a room or property

• receive taxable benefits through work

• begin making pension contributions 

For younger workers, the biggest risk is not usually deliberate tax avoidance or anything dramatic. It is simply not realising that extra income counts. 

A few hundred pounds here and there can affect tax codes, repayments, allowances or charges, especially once more income streams are involved. 

Adjusted net income and student loans

Student loan repayments are usually based on income above the relevant repayment threshold, and the rules depend on your plan type. 

Adjusted net income is not the main term most people need when checking student loan repayments, but your wider income position still matters. 

If you have PAYE income and Self Assessment income, for example, your repayments may be calculated across more than one route. 

The key point is that extra income can affect more than just Income Tax. 

Signs your adjusted net income could be wrong

Your adjusted net income may not be accurate if HMRC does not have the full picture. 

Red flags include:

• you have changed jobs recently

• you have more than one job

• you started a side income

• you receive rental income

• you are on a strange or unexpected tax code

• you stopped or started pension contributions

• your Child Benefit charge looks wrong

• you have unclaimed work expenses

• your payslip deductions changed suddenly 

If something does not look right, it is worth checking sooner rather than later. 

Could you be overpaying tax?

Yes, it is possible. 

People often overpay tax because:

• their tax code is wrong

• HMRC has incomplete information

• work expenses have not been claimed

• pension relief has not been applied properly

• multiple income sources have been coded incorrectly

• emergency tax has not been corrected 

In some cases, HMRC may refund overpaid tax automatically. In other cases, you need to claim it. 

That is why checking your tax position matters. 

RIFT suggestions

If you are near a threshold, do not just look at your salary. 

Look at the whole picture:

• salary

• bonuses

• side income

• rental income

• savings interest

• dividends

• benefits in kind

• pension contributions

• Gift Aid

• claimable work expenses 

This gives you a much better view of whether HMRC is taxing you correctly. 

When to get expert help 

Adjusted net income can be straightforward for some people and more complicated for others. 

It is worth getting help if:

• you have multiple income sources

• you are close to the £60,000 Child Benefit threshold

• you are close to or over £100,000

• you complete Self Assessment

• you have changed jobs recently

• you think your tax code is wrong

• you have not claimed work expenses before 

A quick check can help you avoid unexpected tax charges and spot refunds you may have missed. 

Don’t let HMRC keep money that should be yours 

Adjusted net income is not just another tax phrase. It can affect your allowances, charges and the amount of tax you actually pay. 

If HMRC has the wrong information, or if you have not claimed relief on costs you were entitled to claim, you could be paying more than necessary. 

Many people are surprised to discover they are owed money back.
