Assistance Required for Filing Corporation Tax Return

Hi, I am filing my tax return through HMRC’s services for my company, which was registered on 13 April 2023. While filing, HMRC split the return into two periods: 13 April 2023 to 12 April 2024 (I have already filed this return successfully). 13 April 2024 to 30 April 2024. When I attempted to file the return for the second period, I encountered an error stating that the sales limit of £31,167 has been exceeded and I need to use commercial software to file the return for 13 April 2024 to 30 April 2024. Could you please advise on how to resolve this error? Alternatively, if filing through commercial software is mandatory, can you recommend some free software options to file my return? As the due date is 14 January, I would greatly appreciate your prompt assistance.

The commercial software and service suppliers listed in this guidance have given evidence that they’ve developed software or manage a service (or both), that can produce one or more elements of a Company Tax Return:

It seems that HMRC’s system automatically flagged your sales limit, as your total turnover may have exceeded the threshold. To resolve this, you will need to use commercial software for the second period. Free commercial software options include: TaxCalc (limited free filing for simple returns) GoSimpleTax (offers free filing for basic returns) Ensure you choose one that meets your filing requirements. If the issue persists, contacting HMRC support may also help clarify any system-related concerns.
