Motor tax legislation does not provide for an appeals process.
There is a facility in place to declare a vehicle off the road where it is not going to be in use in a public place. A declaration of non-use must be made in the last month of an existing motor tax disc or renewed in the last month of a previously made declaration of non-use.
The declaration can be made for any number of calendar months between 3 and 12 months i.e. it cannot be made for a period of 1 or 2 months. If a vehicle is subsequently required to be put back on the road, the declaration can be broken at any time simply by taxing the vehicle.
Where a declaration is not made in advance, arrears of motor tax must be paid in full and motor tax paid for a minimum of 3 months before a declaration of non-use can then be made in the final month of the tax disc.
