Correcting Ltd Company Returns

I need to correct a previous Ltd company tax return, but it is more than 12 months since the filing deadline. How do I do this? I also need to submit my 2023-24 return in January 2025. How can I submit this accurately given a previous year’s return is incorrect? Will it not force me to incorrectly offset the losses from that tax return?

Hi ,
 

Amendments to a Company Tax Return must be submitted two years from the end of the relevant Account Period. After this period it is no longer possible to submit an amendment and any existing self-assessment will be left unchanged. To pursue an error you may wish to consider a claim under Schedule 18 of the Finance Act 1998 Para 51 and SACM12005 – Overpayment Relief. To claim, please follow the format set out in SACM12150 - Overpayment relief: Form of claims - Overpayment relief: Form of claims - HMRC internal manual - GOV.UK The best place to find government services and information   . Submit your Income Tax Self-Assessment based on the calculations for the current year on the corrected position from the prior year. Do not offset incorrect losses or carry forwards from the uncorrected return. You should also explain your adjustments in the “additional information” section of the Tax return. State clearly that the figures account for the correction of the previous return. Thank you .
