My partner has had a bill from HMRC to the tune of around £1700, this is due to him not filing his tax returns as he registered for self assessment back in 2017 for a job he didn't end up doing. Its an issue in itself but the kicker is that two years ago he had the same letter and said he had spoken to HMRC and sorted it back then. He's now claiming to not remember the letter or apparently having sorted it back then. I am absolutely livid with him. It feels like he's just dragging me down with him and all his stupid financial decisions to the point in seriously reconsidering our relationship.
