Disagree with a revenue correction notice.

If you receive a revenue correction notice from HMRC and believe the change to your tax return is incorrect, you have the right to reject it. This process applies to taxpayers named in the notice or their authorised agents. To reject a correction, you must follow the specific instructions provided on your notice and submit the required form, which includes providing your National Insurance number and the reference number from the notice. You may also include supporting evidence, such as payslips or invoices, and HMRC will typically respond to your submission within 30 calendar days.
