The government, as announced, is moving to an average 30% cut for presumptions involving cars, real estate, and boats. The most significant change comes in automobiles. Until now, the presumption has been determined almost exclusively by cubic capacity, with discounts for age of 30% (5-10 years) and 50% (over 10). But this was seen as a distortion, since a new vehicle is unlikely to have higher maintenance costs than a fifteen-year-old one. This practice even acted as a barrier to the purchase of new cars. Now, for vehicles after 2010 (up to 15 years old), the objective costs will be determined based on emissions. The scale is: -1-122 g CO2 → €2,000 -123-139 g → +€30/g -140-166 g → +45€/gram -Over 166 g → +60€/gram So a 1,500 cc car with 102 g CO2 had a presumption of 5,800€ (or half if over 10 years old).
