UK tax law treats private car sales differently from business disposals. Private sellers are not subject to Capital Gains Tax on the disposal of personal assets including vehicles, as personal use assets are exempt from CGT. This creates a significant advantage for private sellers compared to other investment assets that might generate CGT liability. ## Tax on Car Sale Rates and Regulations No Capital Gains Tax applies to private car sales. No VAT applies to private used car sales. Company car disposals by businesses may attract Corporation Tax on the gain or allow a deduction for the loss, depending on the disposal value relative to the tax written-down value of the asset. ### DVLA Notification: The Critical Step When selling a vehicle, the most urgent legal obligation is notifying DVLA of the change of registered keeper using the V5C seller's section. This notification protects the seller from offences and fines committed by the new keeper using the vehicle. Failure to notify DVLA within the required timeframe can result in fines and penalty points being issued to the previous keeper. The seller should complete the yellow slip of the V5C logbook and hand it to the buyer at the time of sale. The seller retains the brown slip as proof of notification and should retain it until confirming that DVLA has processed the change of keeper. The buyer should receive a new V5C from DVLA within two weeks. ### Road Tax Does Not Transfer Road tax is non-transferable and does not accompany the vehicle in any circumstances. The seller receives no refund of any unused road tax period at the time of sale, and the buyer must tax the vehicle immediately upon purchase. DVLA's online system enables immediate online taxation for the new keeper. This is one of the most common areas of confusion in private car sales. Buyers who collect a vehicle assuming the tax transfers may find themselves driving an untaxed vehicle until they complete the online taxation process, exposing themselves to an £80 fixed penalty for driving without tax. ### Business and Company Car Disposals When a business disposes of a company car, the disposal proceeds are compared to the tax written-down value of the vehicle to determine whether a taxable gain or deductible loss arises. A gain on disposal of a company car is subject to Corporation Tax, while a loss can be set against other taxable profits. The disposal value of a company car is reported on form P11D as a benefit-in-kind issue when the car is first provided and as a disposal value when it is returned or sold. The difference between the original P11D value and the disposal value affects the total BIK tax paid over the vehicle's life as a company car. ## Frequently Asked Questions **Do I have to pay tax if I sell my car for more than I bought it for?** No. Private car sales are exempt from Capital Gains Tax regardless of the sale price relative to the purchase price. This applies to all personal-use assets including classic cars, supercars, and any other vehicle sold privately. **Can I transfer road tax to the buyer?** No. Road tax cannot be transferred or refunded between sellers and buyers. The seller loses any unused tax period, and the buyer must tax the vehicle from the date of purchase using DVLA's online system. **What happens to the MOT if I sell my car?** The MOT certificate remains with the vehicle, not the seller. The buyer should verify the MOT expiry date before purchase and budget for a new MOT if the current certificate will expire shortly after purchase. **Are car dealers required to charge VAT on used car sales?** Car dealers selling used cars can operate under the VAT margin scheme, which taxes only the profit margin on each sale rather than the full sale price. This allows dealers to sell at prices that include VAT at effective rates below the standard 20 percent.
