If your circumstances change

Your income changes 

You will not have to pay the tax charge if your or your partner’s individual ‘adjusted net income’ for the whole of a tax year is below the threshold.

Use the Child Benefit tax calculator to get an estimate of your adjusted net income changes and see if they may affect the tax charge.

You can choose to opt out or restart your Child Benefit payments at any time.

If your adjusted net income goes below the threshold and you no longer need to complete a Self Assessment tax return, you must tell HMRC.

You’re paying through Self Assessment and no longer need to send a tax return

If you no longer need to send a tax return for another reason, for example if you stop being self-employed - you can pay the tax charge through PAYE instead.

Contact HMRC by phone if you need to close your Self Assessment account and want to start paying the tax charge through PAYE.

You have a new child 

Claiming Child Benefit helps you qualify for: 

  • National Insurance credits, which protect your right to the State Pension 

  • other benefits like Guardian’s Allowance 

Child Benefit proves you (or your partner) support another child. You may pay less child maintenance for children not living with you.

You can make a new claim or just protect your entitlement to the above by:

+  sending a Child Benefit claim form

+  ticking the option to ‘not have the benefit paid’ 

A partner moves in or out

Your situation may change if your adjusted net income is over the threshold and you move in or split up with someone who’s getting Child Benefit.

If both you and your partner have an individual income that’s over the threshold, then whoever has the higher adjusted net income is responsible for paying the charge.

The tax charge applies from the date you move in together to either the date you permanently separate or the Child Benefit payments stop - for example because the child is too old to qualify for Child Benefit

Short periods apart do not count as separation, for example a hospital stay or working away from home.
