It is possible to make changes if you have done a mistake on your self-assessment tax return after filing it, any changes must be made within 12 months of the usual 31 January filing deadline. Somehow if you miss the deadline you can make the changes by writing to HMRC.

3 Reasons to File an Amended Return

You may need to submit an updated return to get a larger refund or because you realised that you owe the IRS more money than you expected.

Some reasons individuals submit amendments to their tax returns include forgetting to declare certain income, recognising that they should have or shouldnot have claimed certain credits, or improperly reporting dependents on their tax returns.

Other typical causes for submitting an updated tax return include receiving late tax documents such as W-2s or 1099s after the original return has already been submitted. You must file an updated return to reflect any income omitted from your first return.

1. Ensure that there are no mistakes or omissions in your revenue.

If you find out after you have already filed that you forgot to include income on your return

(for example, from a Form W-2 or 1099), or if you get a corrected information statement that

has different amounts of income or withholding, you will need to file an amended refund to

correct the error.

This is the case regardless of whether you are due a higher tax refund or will have a greater

tax liability. If you don't revise your return and you wind up owing more money in taxes, the

Internal Revenue Service (IRS) will most likely give you a CP2000 notice, which may come

with severe penalties.

2. You should consider changing your filing status.

If the conditions are right, you may switch your file status to one that provides you with more

favourable tax treatment.

For instance, if you claimed Head of household status when you were eligible for the Single

filing status, your standard deduction would be reduced by $3,000. It is not always possible

to modify your filing status since your circumstances determine it, but if you find that you

need to, it is a valid reason to submit an amended refund UK.

3. Change your deductions.

If you itemise your deductions erroneously, claimed certain expenditures in error, or

inadvertently included or excluded a dependent, you must submit an amended refund UK to

rectify these mistakes. This might avoid issues in the future, such as notifications or an audit

by the IRS.


After making alterations to your tax return after filing it, you’ll need to make any amendments within the first year of filing it. Self-assessment errors are frustrating but they can be managed. Most people file their Self-assessment returns online, and you can file your return on paper as well. You must have all the documentary proofs related to the changes.

Once your tax returns have been filed, you’ll likely keep a little patience. You shouldn’t file a second tax return, since it can create confusion and slow down the processing.

While you will become confirmed that, HMRC received your amended refund file through mail or e-filed, then calling them for the information won’t speed up the process and it will make it more problematic for them to do their job.
