Important Changes to Corporation Tax Notices

Changes to Corporation Tax Notices – what you need to know

From September this year, companies are expected to check the CT Online View Liabilities and Payments (L&P) rather than rely on paper copies of the letters and information traditionally sent out by HMRC.
Businesses can no longer rely on HMRC to send out paper reminders for corporation tax returns 28 days before the due date, so businesses should set up an internal reminder system. As currently happens, we will remind you of the payment due date when we send out details of your liability.

You can check a corporation tax return status and return details online.

HMRC will no longer send out the following letters and information:

• Acknowledgement of receipt of a corporation tax return (CT620 ACK)
• Letter showing the key corporation tax filing and payment dates (CT610/CT610A)
• Budget insert which shows the changes to corporation tax following the Budget and is usually issued with the notice to deliver a company tax return
• Authorising your agent form (64/8) which used to be issued with the “Information for new companies letter” (Form CT41G)
• Filing reminder letters which used to be issued 28 days before the return due date
• Notes issued with the corporation tax return
• Various other corporation tax form such as the notice of amendment to a return
