I have noticed that both my husband and I have had a deduction made to our tax codes for untaxed interest.

We are both only in receipt of company pensions and are entitled to the standard rate of tax-free income so surely should be allowed £1,000 personal savings allowance.

Interest received in both cases is less than this allowance. In my case I only receive £7,000 a year in pensions so this makes any deduction even stranger.

Can you please advise if this is a common problem. I know in my case it doesn't make any difference to my income but my husband is now paying a small amount of tax which I believe is incorrect.

My husband wrote to HMRC last year about this but has never received a response from them.
