About 70 percent of the annual marchamo is taxes. And it is the Ministerio de Hacienda that approves the formula that assesses the value of each motor vehicle or other craft that is subject to the tax.
Tuesday the ministry issued a statement defending its calculations. It said the formula has been reviewed by the Escuela de Estadística de la Universidad de Costa Rica and was fixed by law.
The taxes also are levied on boats and aircraft. The rate ranged from 1.2 to 3.5 percent of assessed value.
However, there is growing concern that the valuations are out of step with real market value.
The ministry had an answer for that, too.
If anyone believed that the assessed value of the vehicle is incorrect, there is a way to seek a change. The vehicle owner has to argue the case by using copies of classified advertising and similar evidence. Most will not because there is a lot of paperwork involved.
The situation has caught the attention of some lawmakers and those in the vehicle trade.
