What that tell me then is,

I transfer ownership as i owed back tax. It give ten days for Non use immediately following purchase of a second hand vehicle.

If you only have 10 to fill the form in and it take 12 to process are you hit with 3 months tax?

One to watch out for. The Tax office processed my form on the 19 and the car was not registered on till the 30. I'm in the system so i should be fine.

Looks like Leins was right as well they might be charging next year to process the form
