By MoneyBees

Work out your car or motorcycle road tax from LTA's formulas: by cc for petrol and diesel, by kW plus the flat component for EVs, hybrids, and the surcharge after 10 years.

Frequently asked questions

How is road tax calculated in Singapore?

For a petrol car, LTA sets a base amount by engine capacity and multiplies it by 0.782. A 1,598cc car pays (S$250 + S$0.375 x 598) x 0.782, which is S$370.86 every 6 months.

How much road tax does an electric car pay?

Road tax is based on the motor's power rating in kW, times 0.782, plus an Additional Flat Component of S$350 every 6 months. A 100 kW car pays S$400.78 plus S$350, so S$750.78 every 6 months.

How is road tax worked out for a hybrid?

LTA works out the road tax twice, once by engine capacity and once by the electric power rating, and you pay the higher amount. Hybrids do not pay the electric car flat component.

What is the road tax surcharge for old cars?

Once a vehicle is more than 10 years old, LTA adds a surcharge of 10% of the road tax. It goes up 10 points each year, to 50% once the vehicle is more than 14 years old.

Do diesel cars pay more road tax?

Yes. A diesel car pays road tax by engine capacity plus a special tax that depends on its emission standard. For a Euro V car it is S$0.20 per cc less S$100, at least S$100, every 6 months.

Can I pay road tax for 6 or 12 months?

Either. Off-peak cars, revised off-peak cars and weekend cars can only renew for 12 months.

Where do I check the exact amount?

OneMotoring shows the road tax payable for your vehicle number. This calculator uses LTA's published formulas, so its figure can differ by a few cents from rounding.
