Submitting Amended Tax Returns - Self Assessment Software

Andica Self Assessment Software for Individuals (SA100), Partnerships (SA800) and Trust and Estates (SA900) provides feature to submit amendments to the returns that a tax payer has already submitted to HMRC.

Customers can make changes or correct mistakes to their tax returns and submit an amended return through the software regardless of where the original tax return was submitted from and how it was submitted.

Submissions of amended self assessment tax returns are subject to deadlines published on HMRC's website and limitations to the numbers of amended returns that can be submitted. At the time of publication, HMRC have a limit of maximum of 9 submissions for amended returns.

An amended tax return should only be submitted if you want to modify the original tax return that has been recorded by HMRC within their system.

Brief explanation of an Original and Amended tax return .

Submitting Amended tax returns where the original return was submitted through Andica Software:

Summary below is provided on assumption that the software and tax return data for tax year for which you want to send amended returns has been installed and is accessible on your computer. If not, you can purchase a new software licence to process amended returns.

  1. Start the software and open the record for which you want to submit an amended return.

  2. Review the tax returns from the start and check all the entries and make any amendments you require. Navigate by clicking 'Next' and 'Finish' on all sections and review your returns and reports.

  3. Access the 'File By Internet' routine using one of the methods as described in the user guide.

    On the 'File By Internet' screen, select the 'Tick if this is an amended return' option

    You should only do this if you have previously successfully submitted your returns using 'Live submission' and HMRC have recorded the original submission in their system and you now want to resubmit the returns with an amendment to the earlier returns.

  4. If you had used this software for 'Live submission' of the original tax return and the submission was successfully accepted by HMRC, you will get a message "Your tax return may have already been submitted using the Live submission. Click OK to Preview, Print or Clear the earlier submission receipt. Click Cancel to abort this submission process." Click OK.

  5. 'File by internet details' screen will be displayed with submission receipt of the last submission. Ensure the correct submission receipt is selected.

  6. Click 'Clear' and confirm 'Yes' on the message box to clear the submission history of the previous submission.

  7. The submission will now start.
