For a few years, we had income from letting out our home whilst we lived in tied accommodation with my husband's job. I did all the tax returns in my name during this time, declaring the full income less allowable expenses and then paying the tax due. It now seems this was a cock up and we should both have been doing a tax return, declaring it 50:50. Does anyone know if there are implications from this please as we are shitting ourselves that it means somehow we might have more to pay? Or is it just the case that it's an admin thing that just needs to be clarified with HMRC? Thanks ever so much, if anyone knows and can help. (Will see a tax advisor v soon if necessary. )
