Sole Trader - Missed supplier invoice Tags after Accounts submitted

Hello,

I missed several Supplier invoice Tags in the last accounting period. Unfortunately the Period is Locked and I have submitted my Tax Return to the HMRC. I do not at this stage wish to re-submit amended accounts to the HMRC as this will incur additional Accountant fees . I just want to move the dates of the transactions into this accounting period. I did not pay tax this year, so no real tax issue. Can this be done?

You would wither need to rollback the last year-end journals which will unlock the period or amend the year-end journal to move the balance elsewhere.
