Income From Savings

Thank you for the replies.
My dad pays a small amount of income tax due to having a state pension AND a private pension. Was I incorrect in thinking,  that as the building Society deducted the tax at source, that it would not mean that he would have to pay Tax again on the interest?

yes, you are correct it your thinking.
once tax is deducted at source by the building soceity before any interest is paid, your dad will not recieve a bill for any additional tax.

so easy to have said yes, and the answer would be right in both cases....... very confusing...
