Motor tax is payable on an annual, half-yearly or quarterly basis. The rates applicable to the half-yearly and quarterly options are 55.5% and 28.25% of the annual charge, respectively. These relativities have remained generally consistent since the 1960's.
Of the 4,960,487 motor tax discs issued in 2020, 1,985,929 were annual, 730,453 were bi-annual and 2,244,104 were quarterly.
Of the 3,762,793 discs issued to the end of September 2021, 1,675,285 were annual, 548,870 were bi-annual and 1,538,638 were quarterly.
Gross motor tax receipts in 2020 were just under €940m. Gross motor tax receipts to the end of September 2021 were almost €721m.
The loss to the Exchequer arising from the elimination of the additional charge for these options has been estimated at just under €41.3m, based on the volume of transactions for 2020. The loss of income that would arise from changing these arrangements would have a negative impact on the total collected via motor tax and would have to be borne elsewhere in the motor tax system or through the taxation system generally.
