Require self assessment statement with paying in form

My mother who is 100 is worried because we haven't received the paperwork to confirm how much tax is due and how and where to pay it. I have tried ringing the 3300 number and kept on hold before being cut off. I simply want to know from HMRC whether the statement has been sent and the possibility of it being emailed to me. Because we filled in a paper self assessment I don't think it can be paid online as we don't have an account. And as we have no specific amount we can't pay at a bank. Help please !!!!

Hi,

You can make a payment online even if the return was filed by paper. If she has not received a letter stating the amount due you will need to contact our Self Assessment team again.

Self Assessment: general enquiries

Thank you.
