Use form TC689 to authorise someone else (an 'intermediary') to act on your behalf for your tax credits or Child Benefit. Intermediaries – use the PDF version of form TC689 if you require a printed version to complete with your client, for example during a home visit.

Use form TC689 if you want an intermediary, such as Citizens Advice, to act on your behalf for your tax credits or Child Benefit.
Don’t use form TC689 to authorise a paid agent such as an accountant or other professional adviser to act on your behalf. You should use form 64-8 instead.
Before you start
If you are using an older browser, for example, Internet Explorer 8, you’ll need to update it or use a different browser. Find out more about browsers.
You’ll need to fill in the form fully before you can print it. You can’t save a partly completed form so we suggest you gather all your information together before you begin to fill it in.
