Tax status and tax cost are different
A tax check tells you whether the vehicle is currently shown as taxed or SORN. Tax cost is about the rate that may apply when you tax the vehicle yourself after purchase.
Registration date matters
UK Vehicle Excise Duty rules have changed over time. Two cars with similar emissions can therefore have different tax treatment if they were first registered under different tax systems.
Use the rate as part of your running-cost comparison
Vehicle tax is only one ownership cost. Compare it with fuel, insurance, servicing, tyres and expected maintenance before deciding which used car offers the best overall value.
