Looking at the direct.gov.uk web site, it tells me that... "If your vehicle has been untaxed, because you've just bought it, the tax disc has run out or a SORN is in force, you can tax from the first day of the month in which you apply." "If you want the tax disc to start on the first day of the next calendar month, you cannot tax your vehicle more than two days in advance." The first suggests that if my bike's SORNed and want to tax it to start from 1 March, I'll have to tax it on the 1st March or later. With that being a Sunday, I'll have to wait until the Monday, which is too late. Contrary to that, the second paragraph suggests that if I want the tax to start on 1 March, I can apply for it up yo 2 days early, i.e. Friday or Saturday. Can anyone confirm that should I go into the post office on Saturday I'll be able to start my tax off from the Sunday?
