Ignorant question about savings interest and tax returns
Having always worked in the public sector, for a modest salary, I have never done a tax return in my life until very recently, when it became necessary due to becoming an accidental landlord. Most of my income is occupational pension taxed at source. If I have money in savings accounts on which I earn interest, am I supposed to list all the interest on the tax return? I have never done so. Do they have other ways of finding out what interest I may be earning? Please excuse this naive question. Thanks for any genuine advice.

Of course you ahould have, it's a return of all your taxable income. How much are we talking in interest?
HMRC are notified of it and if there is additional tax to pay then there may be interest and penalties charged.

Yes, unless the accounts are ISAs.
How did you answer this question?

The interest earned would have been in the low hundreds, if that

Giving a clearly false answer to a simple yes/no question, and then formally declaring that you'd answered it truthfully, is obviously not a good idea, but if doing so didn't actually affect your tax liability (assuming taxable interest would have fitted within your personal savings allowance) then it's unlikely that you'd be subjected to any punitive action from HMRC.

The savings providers will send details of your interest earned to HMRC . So for tax year 25/26 they will send the details around about June/July 2026.
At that point probably HMRC will notice you did not declare any interest on your tax return and will query that.

You can go back and amend the tax return to include the interest you should have declared. (Start by ticking Yes instead of No to that question and then you'll get the pages you need to fill in) Don't leave it too long - I think there is a time limit for amending self assessment tax returns.

You need to find the correct figures for the interest earned. You will have been sent (or possibly notified by email of its availability online) a statement/certificate of the interest earned by each of your savings accounts in the last financial year.
