Well credit where credit due - a pretty quick response:
Motorists who choose to tax every six months are not being discriminated against. It is an option provided to those who prefer not to commit to the full annual rate and recognises that a twelve month disc may not always be appropriate.
Vehicle Tax is set by law at an annual rate and there is provision for a tax disc obtained for six months, calculated at half the annual rate of vehicle tax plus 10% of the total sum. The extra 10% surcharge covers the cost of the extra tax disc, the reminders sent out to the customer, and the handling charges involved in the issue of two discs. To waive the premium would encourage a general switch from yearly to twice-yearly taxing. This would inevitably result in higher costs for a tax disc, which might have to be reflected in the overall cost of vehicle tax discs.
I don't agree with this - indirect discrimination is occurring as those who prefer/need to pay bi-annually are being charged an excessive premium. As to the amount being to cover costs - nonsense! For some, vehicle tax is around £450 a year so how is £45 justified when for others it is £100 and therefore a £10 surcharge? I've also asked how much a tax disc and reminder costs so we'll see what comes next. Also why instalments aren't possible when many other taxes can be paid in instalments.
Not quite sure where I'm going with this but I don't feel like letting go just yet - I really don't think it's right!
