With effect from 1 January 1993 the Revenue Commissioners have been given statutory responsibility for maintaining a register of all vehicles in the State and for collecting vehicle registration tax (VRT). The Finance Act, 1992, provides that the VRT charged in relation to a car shall be a percentage of its value and that the value shall be taken to be the open market selling price (OMSP) of the car at the time of the charging of the tax thereon.
In the case of new cars the OMSP is the price, inclusive of all taxes and duties, declared to the Revenue Commissioners by the manufacturers or sole distributor. In the case of second hand cars, being registered in the State for the first time, the OMSP is determined so as to ensure that the VRT chargeable on the vehicle will be equivalent to that residing in an equivalent model of the same age and condition already registered in the State. In determining this value the age, condition, mileage etc., are taken into account as are any enhancements or extras that may be fitted.
The Commissioners maintain a computer database or car models and prices based on the age and specification of the vehicle. To obtain the VRT payable specific details of the car are entered into the computer which will then calculate the OMSP and appropriate VRT payable. This computer database is used by all Vehicle Registration Offices thereby ensuring consistency in the calculation of VRT from office to office. The database is being constantly updated to take account of models not previously encountered, and to allow for the passage of time.
The VRT database is not available in hardcopy. Because of the size of the database, and the frequency of updates, it would not be practicable to produce a printed version. It should be noted that prior to the introduction of VRT there was no centralised database of secondhand car prices and the Customs Tariffs never contained such a listing.
