Update (31st January, 1am): Well, the good news is that I think my first ever tax return has been entirely filled in. I’m sure I’m being very generous to the tax man, but such is the price of not being good with these things. The bad news is that the tax website has entirely stopped working, so I’m unable to be sure that they got it (I didn’t see a ‘we’ve got your tax return’ screen, though I did get an encouraging e-mail). I’m also unable to pay my tax, so at this moment the £100 fine is still coming my way. Anyway, giving up and going to bed.
Update (31st January, 9am): All done and paid. Hurrah!
