Can I email my tax return to HMRC?

As per title, can I send the pdfs via email or do I need to print them and send them via post? (I can't use online services because I do not have access to my account and HMRC has no help for me, so I have to go paper tax return). And if I do have to print them, where do I send them exactly? Is the following correct? Self Assessment HM Revenue and Customs BX9 1AS United Kingdom Last question: I know I'm late and I will probably get a £100 penalty but I'm still within the three months, so I shouldn't be charged with the bigger penalty. What happens if they don't open the letter within the end of January? Will I get a bigger penalty and then I have to appeal it or I'm just not going to get one? Thanks

Hi,

We would only accept the returns by post, the address you gave is the correct one. When a return is received we note on the system the date of receipt, even though the return will not be processed until a later date.

Thank you.
