I paid my self assessment tax online today using a debit card through HMRC's website.
Within minutes I received a warning security text from my bank telling me that my debit card had been used to make an overseas transaction. I should call if I'm concerned.
Well - I was concerned that HMRC might somehow be involved in some offshore banking scam.
So I called LloydsTSB. Seems the text message was a mistake. Paying the taxman does not, after all, involve an overseas transaction! Phew.
