Electric car tax: build an annual budget for today and 2028

Start with the question you are actually answering

A useful tax budget starts with a date, rather than a car badge. “What will I pay when I renew this year?” and “What might I need to put aside for 2028?” are different questions. A combined number without those dates can look precise while answering neither.

For an ordinary battery electric passenger car, write down its first-registration date, the start of its next tax year and its original list price including relevant options. Then make a separate estimate of annual miles. Our examples assume no exemption, a full annual renewal and one annual payment. They do not include charging, insurance, servicing or depreciation.

A current bill: start with the two existing components

For 2026/27, standard annual VED is £200 and an eligible expensive car adds £440. The worked current example below renews on 1 October 2026: a car first registered on 1 October 2025 with a £35,000 original list price. Its calculation is £200 + £0 = £200. The mileage charge has not started.

Divide £200 by 12 and you get £16.67 as a rounded monthly saving target. That is a budgeting exercise, not the amount DVLA will collect each month. Payment frequency can change the actual charge: the published standard-rate total for twelve monthly Direct Debit payments is £210. Compare the full annual amounts when choosing how to pay.

A future illustration: add miles, then stress-test them

The announced eVED launch rate gives a simple planning formula for a BEV: annual miles × £0.03. In the 2028 examples we hold today’s £200 VED and £440 supplement constant. Actual future VED may change; the figures are illustrations, not bills issued by DVLA.

At 8,000 miles the mileage component is £240. At 18,000 miles it is £540. The £300 gap follows entirely from 10,000 more miles; it does not depend on the car’s battery size. Adding a £440 supplement to the higher-mileage example raises the illustrative total from £740 to £1,180.

Turn the illustration into a reserve you can use

A £440 annual illustration would mean saving about £36.67 each month. £1,180 would mean about £98.33. Keep those reserves separate from your energy budget so that a change in public charging prices does not hide a tax shortfall. Revisit your mileage estimate after a house move, a new commute or a change in working pattern.

For a sensitivity check, every additional 1,000 BEV miles adds £30 at the announced launch rate. An extra 4,000 miles would therefore require another £120, or £10 per month as a saving target. This lets you test a plausible change in use without pretending to forecast your journeys exactly.

Know when the calculation stops being suitable

The calculator covers annual renewals from the second year. It does not calculate a new car’s first licence, special exemptions or part-year billing. A renewal spanning April 2028 needs transitional treatment rather than a full-year mileage charge. Use the official renewal notice for an amount due now, and recheck published rates before relying on a future budget.
