what to do if you need to change your tax returncreative77
If, like us at Appleleaf Accountancy, you made it and breathed a sigh of relief at the end of January after meeting the self-assessment tax return deadline for 2018/19, well done it is out the way for another year.
However, what can you do, if anything, if you suddenly realise in your haste you need to correct your return?
If you have made a mistake on your return, for example entered a number incorrectly or forgotten to include something, all is not lost. As long as you are within the time limit, the error can be corrected by filing an amended return.
If you are in time to file an amended return, the process that you need to follow will depend on whether you filed your return online or on paper.
If you filed your return online, you simply amend your return online. To do this:
- Sign in to your personal tax account using your User ID and password.
- Once in your account, select ‘Self-Assessment Account’. If this does not appear as an option, simply skip this step.
- Select ‘More Self-Assessment details’.
- Choose ‘At a glance’ from the left-hand menu.
- Choose ‘Tax Return options’.
- Choose the tax year for the year you want to amend.
- Go into the tax return, make the changes you want to make, and file the return again.
Remember to check that it has been submitted and that you have received a submission receipt.
Check the revised tax calculation too in case you need to pay more tax as a result of the changes, but remember to take account of what you have already paid.
If you opted to file your return on paper by 31 October 2019, to make a change you will need to download a new tax return. This can be done from the www.gov.uk website.
Fill in the pages that you wish to change and write ‘Amendment’ on each page. Make sure you include your name and unique taxpayer reference (UTR) on each page too. Send the corrected pages to the address where you sent your original return.
If you used commercial software to file the return, contact your software provider to find out how to file an amended return. If your software does not allow for this, contact HMRC.
You have until 31 January 2021 to make changes to your 2018/19 tax return.
If you have missed the deadline, you will need to write to HMRC instead. This may be the case if you find a mistake in your 2017/18 return after 31 January 2020. In the letter, you will need to say which tax year you are amending, why you think you have paid too much or too little tax and by how much. You have four years from the end of the tax year to claim a refund if you have overpaid.
changes to the tax bill
If amending the return changes the amount that you owe, you should pay any excess straight away. Interest will be charged on tax paid late. If your 2018/19 liability changes, your payments on account for 2019/20 may change too.
If as a result of the changes made to the return you have paid too much tax, you can request a repayment from your personal tax account.
