Before you start

You'll be able to update 1 or all of:

  • if you've got back together with the person you pay child support to or receive it from
  • the children leaving your care or no longer qualifying children
  • your dependent children
  • recognised care, either adding or changing it
  • any other changes you want to tell us about.

Go to your child support account

You'll find your child support account panel on the homepage in your myIR account. 

It will say either: 

From the account panel, select 'More...'

Go to 'Child support change of circumstances' then select your change type

Follow the prompts to enter the requested information.

What happens next

If there are changes to your payments, we will send you a new Child support to pay or Child support entitlement letter. If you're registered for myIR, you'll receive this electronically, otherwise we'll send it to you by post.

You can see new payment details in myIR.
