HM Revenue and Customs (HMRC) has launched an initial trial that will end the sending of Corporation Tax reminder letters.
Launched earlier this month, the trial is designed to continue HMRC’s push to streamline their services.
It will encourage businesses to complete their tax returns digitally and the tax authorities target to reduce the number of letters they send by 70 per cent.
Only a small number of companies that have agents are involved in the trial at this stage, but there are plans to expand the trail to more businesses, including ones without agents.
With the trail set to run until December 2025 and other letters for Corporation Tax stopped, its important businesses know their Corporation Tax deadlines, can adapt to the changes and are comfortable with filing tax returns digitally.
What Corporation Tax letters have HMRC stopped sending?
Prior to the launch of this trial, in June 2025, HMRC announced it had stopped sending businesses a series of Corporation Tax letters.
That list included CT205/A, CT207, CT209, CT603A and CT608. In short, HMRC is not sending return reminders, interest statements, payment receipts, agent list of issued notices to deliver company tax return and instalment payment reminders.
HMRC stress this is part of their continued drive to improve its services for taxpayers and businesses by incorporating digital methods.
While this puts emphasis on HMRC’s commitment to their transformation roadmap, it also means businesses will need to know their deadlines and ensure they have plans in place to avoid any interest charges.
What is the latest trial introducing?
Having stopped sending several Corporation Tax letters last month, the latest trial is focused on CT208/A, which is payment reminder letters.
Running until December 2025, this would mean businesses involved would not receive a payment reminder letter and would need to look online to ensure they know when they must pay their Corporation Tax.
HMRC will monitor the trial throughout the process, confirming it will stop it at any point should the trial pose difficult challenges and have a negative impact on customers.
What does the trial and HMRC’s change in approach mean for my business?
HMRC is pushing ahead with its transformation roadmap, which is designed to improve digital services for individuals and small businesses and make their services accessible for all.
We have seen HMRC introduce a brand-new PAYE system for over 35 million UK Taxpayers. The Corporation Tax changes very much focus on businesses, encouraging them to embrace the digital services and utilise that to put measures in place.
Taking away Corporation Tax letters means businesses must ensure they know their deadlines but also where they can access statements and receipts.
You need to take responsibility and ensure you have the ability to access all the information, and you need and know your deadlines as failure to pay on time has serious consequences.
The current rate of interest sits at 8.25 per cent and should you not pay your Corporation Tax on time, the interest would be added on top.
