Self Assessment SA316 and SA251

Dear HMRC staff, My husband received SA316 and successfully submitted his self assessment 2023-2024 tax return to declare his saving interest .A reference number was given. The HMRC apps tax calculation stated that he is no need to pay the tax. However , we received SA251 today and inform us to send the tax return . May I ask. : 1)Since he had already submitted his tax return successfully, therefore it is nothing to do with the SA251 form . AmI right ? 2) The HMRC apps already state that he is no need to pay tax and the HMRC will not send us the letter for this tax return . The calculation in the apps is already the confirmed final calculation . Am I right ? Thanks for your advise . Thank you

Hi 

The SA251 exit letter is usually issued when a taxpayer's record has been automatically selected to be closed, after our systems have identified that the recipient will likely have no Self Assessment criteria in future.
It's probable that this is in response to our systems receiving the submitted return.
To confirm that the submitted return has been received, though, we would need to check your husband's record - to allow us to do this, contact us by webchat or phone via Self Assessment: general enquiries

Thank you

Dear HMRC staff, Thanks for the explanation. I also received SA251 exit letter in last year (May 2024) stated that 2023-24 is the last SA return. After checked, I haven’t any saving interest and no other income in this tax year 2024-25. So I don’t need to submit SA return for the tax year 2024-25, am I correct? Thanks for advise.

Hi,
That is correct. You can also confirm the closure of your record through your personal tax account, or by contacting our Self Assessment team.
