\text{ICE Base Tax (1001-1600cc)} = [500 + 0.75 \times (cc - 1000)] \times 0.78 \\
\text{Age Surcharge (Age > 10 yrs)} = \text{Base Tax} \times (10\% \text{ to } 50\%) \\
\text{EV Annual Tax} = \text{Power Rating (kW) Tiered Tax} \times 0.78 + \text{AFC } (S\$700) \\
\text{6-Month Road Tax} = \frac{\text{Annual Road Tax}}{2} \times 1.05LTA road tax for petrol cars is calculated on engine capacity tiers multiplied by a 0.78 factor, with an age surcharge between 10% and 50% for cars older than 10 years. Fully electric vehicles (EVs) are taxed on maximum motor output (kW) plus an Additional Flat Component (AFC) of S$700/year to recover fuel duties. Renewing road tax for 6 months incurs a 5% administrative surcharge.

Petrol cars in Singapore contribute to road upkeep via fuel excise duty paid at the pump. Because EVs do not consume petrol, LTA introduced the Additional Flat Component (AFC)—phased in and fixed at S$700 per annum from 2023—to level road revenue contributions.
Once a car passes 10 years, LTA levies an age surcharge of 10% in Year 11, scaling up by 10% each year to a maximum of 50% from Year 15 onwards. For instance, a S$1,200 annual tax jumps to S$1,800 after 15 years.
Yes, renewing for 12 months is cheaper. Paying road tax on a 6-month basis includes a 5% surcharge (Formula: Annual / 2 * 1.05). Paying twice over a year means you incur 5% more tax overall.
