## How this works
LTA sets road tax per 6 months by formula. For petrol cars it is based on engine capacity (EC): S$200 up to 600 cc; S$200 + S$0.125 per cc above 600 up to 1,000 cc; S$250 + S$0.375 per cc above 1,000 up to 1,600 cc; S$475 + S$0.75 per cc above 1,600 up to 3,000 cc; and S$1,525 + S$1 per cc above 3,000 cc. Each result is multiplied by 0.782. A 12-month renewal is twice the 6-month amount.

Electric cars are taxed on the motor's maximum power rating in kW: S$200 up to 7.5 kW; S$200 + S$2 per kW up to 30 kW; S$250 + S$3.75 per kW up to 230 kW; S$1,525 + S$10 per kW above that, each × 0.782, plus an additional flat component of S$350 every 6 months. Petrol-electric hybrids are worked out on both engine capacity and motor power, and pay the higher.

Motorcycles pay S$40 up to 200 cc, S$40 + S$0.15 per cc up to 1,000 cc, and S$160 + S$0.30 per cc above, × 0.782 per 6 months (electric motorcycles use kW, plus a S$100 flat component). Vehicles more than 10 years old pay a surcharge of 10% of road tax, rising 10 points a year to 50% for those more than 14 years old. This tool applies it to the formula amount; LTA's road tax enquiry gives the exact bill.
