Tax on savings interest.

[oncemoreuntothebeachdearfriends]

I've de-registered for Self-Assessment tax return, & it's been accepted by HMRC.
However, I've probably exceeded the £1000 limit on savings interest for 2024/25.
Is this income reported automatically to HMRC? Or do I need to tell them ?

The info on their website appears to contradict the info in their letter to me.

Thank you.

Do you use up your personal tax allowance on earnings from employment?

The banks and building societies must report interest paid to their customers to HMRC by 30th June. Your tax record will be updated automatically with your figures.

If you owe tax and you’re not in Self Assessment you’ll get a P800 calculation telling you how much you owe on the basis of what your bank/building soc report. It would likely arrive in July or August but could be later. HMRC would try to collect the underpayment by updating your tax code with your employer or pension provider. If they can’t you’d get a bill with instructions about how to pay.

I think that’s right, anyway.

Thanks for the replies.

Yes, income is greater than personal tax allowance.

That's a relief. Their letter mentioned a penalty if I didn't tell them everything, but all my income is reported .
