Government projections indicate that roughly 5.6 million vehicles will be subject to this tax in the 2028-29 fiscal year. The Office for Budget Responsibility has estimated revenue of £1.1 billion for that period. Revenues are expected to grow to £1.435 billion in 2029-30 and reach £1.865 billion by 2030-31. The implementation process now includes legislation, payment systems, mileage verification, refunds, penalties, and procedures for appeals and disputes. Motorists will start paying this fee when they renew their vehicle tax after April 1, 2028.
