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.
This form gives your written consent for HMRC to exchange and disclose information relevant to the compliance check with the adviser named. It relates only to the compliance check of the period(s) that you enter on this form and covers all matters administered by HMRC that are being checked.
This is a temporary authorisation and will not cancel or amend any permanent authorisation that you have already sent to HMRC.
