Bank of HMRC - overpaid tax interest

[borderreiver]

HMRC only send you letters for paying money back even if you contact them by email.

Exactly, that was my point!

Thanks for the concern guys but it was legit.

Got an email (due to having paperless notifications set on the government gateway thing where you log in for self assessment and company stuff like VAT returns) saying I had a new message and to log into my HMRC account to access it. No link or anything in the email for security reasons.

Logged onto the gateway and accessed the message about the overpayment and refund due. Went into the side bar options to see a breakdown option showing it was accumulation and interest thereof going back to 2010.
