Do I have to restate or refile my previous accounts to receive R&D tax credits?

Generally, you don’t need to restate or refile. Claims are treated as a prior-year tax adjustment, meaning they are made through your corporation tax return (CT600) instead of changing your published statutory accounts. This allows you to claim for qualifying R&D costs up to two years after the end of the accounting period.

You can alternatively choose to amend your prior-year accounts. Some businesses do this to show the R&D tax credit as income or to restate tax balances, but it’s not a requirement for HMRC.

Accounting treatment does depend on whether you’re claiming through the legacy schemes (SME or RDEC), or the merged scheme, but in either case, you still don’t need to restate your accounts.

It’s important to note that any amendments should be carefully considered with your accountant to ensure consistency between your statutory accounts and corporation tax filings.
