Most people in the UK don't have to do a tax return, if you do have to do a tax return doing it online (at least if you have the relevant information handy) isn't difficult - probably takes me 30 minutes on a simple year and on a complex year I pay an accountant to do it.
Exactly, if our going to allow all of the hackable information to be stored online by your government so you can shave 20mins from a yearly task then your a fuc*g idiot.
Exactly as happens when I pay my UK taxes online!
