My elderly mum is getting this every year.
Her income is a state pension, a pension from last UK employment, and a pension from Hungary.
This was all gone through by HMRC in recent years and I believe her tax code has been adjusted to take care of the last one.
She had some company shares but these have been sold.
The thing is that she was never more than a basic rate taxpayer.
What is the procedure for stopping the tax return being sent to her?
