Savings Interest

If I owe more in taxable savings interest than could be collected by changing the tax code on my very small personal pension (my only other income), how will it be collected by HMRC. Will I have to fill in a self assessment tax form at the end of this tax year?

Hi,

No, you would receive a simple assessment tax calculation to collect the underpaid tax. You can see guidance here:

Thank you.
