Vehicle Tax Shake-Up: Why Some Drivers Could Soon Face a £5,690 Bill

If you thought your car tax bill was already painful, brace yourself. The Treasury has confirmed a fresh round of Vehicle Excise Duty (VED) changes landing in April 2026, and for owners of the most polluting new cars, the numbers are eye-watering. We're talking about a first-year charge that could hit £5,690 for a single vehicle, a figure that has understandably caused a stir among motorists already squeezed by fuel costs, insurance premiums and the cost of living more broadly.

This isn't a one-off headline grab. It's part of a wider, ongoing recalibration of how the UK taxes vehicles, one that has been reshaping the rules for years and shows no sign of slowing down. Here's what's actually changing, why it matters, and what you need to do about it.

What's Actually Happening

According to reporting from the Mirror, the Treasury has responded to questions about the upcoming vehicle tax changes confirming that from April 2026, petrol and diesel car owners face increases to their annual VED, alongside a substantially higher first-year rate for the most polluting new vehicles entering the market. The £5,690 figure being quoted relates to that first-year charge, sometimes dubbed the "showroom tax", which is levied based on a car's CO2 emissions at the point of first registration.

This first-year rate system has existed in some form since 2017, when the government overhauled VED to link the initial tax bill directly to how much carbon dioxide a vehicle emits. The idea was straightforward: make the dirtiest cars more expensive to buy new, nudging manufacturers and buyers alike towards cleaner options. What's changed over the years is just how steep that penalty has become. The top-band first-year rate, for cars emitting the most CO2, has risen sharply in recent Budgets, and April 2026 marks another significant jump.

Beyond the headline first-year charge, the story also confirms that standard annual VED rates for petrol and diesel cars are rising too. These are typically adjusted in line with the Retail Prices Index (RPI), a mechanism successive governments have used to quietly increase the tax take each year without it looking like a dramatic policy shift. Multiply that modest-sounding percentage rise across millions of vehicles on UK roads and it adds up to a substantial amount of extra revenue for the Treasury.

Why This Matters Beyond the Headline Figure

It's easy to read "£5,690" and assume this is scaremongering, or that it only affects a tiny handful of supercar owners. The reality is more nuanced, but arguably more concerning for ordinary drivers.

First, the first-year rate applies to new cars only, and specifically to those in the highest emissions bands. That means it disproportionately hits larger petrol and diesel vehicles, including some SUVs and performance cars that remain popular with UK buyers despite the ongoing shift towards electrification. If you're looking at a new car in the coming year, this is a cost that needs factoring into your budget from day one, not something you can shrug off as somebody else's problem.

Second, and more broadly relevant, the increase to standard annual VED rates affects millions of existing car owners, not just those buying new. Whether you drive a five-year-old diesel estate or a modest petrol hatchback, your renewal notice from the DVLA is likely to arrive with a higher figure attached in 2026. For households already juggling rising insurance costs, petrol prices, and everyday bills, this is another line item creeping upwards.

There's also a bigger picture here worth understanding. VED has increasingly become a tool not just for raising revenue, but for steering driver behaviour. The government has been open about wanting to accelerate the transition to electric vehicles, and taxing high-emission petrol and diesel cars more heavily is one of the levers available to do that. Electric vehicles themselves are not exempt from this recalibration either. Since April 2025, EV owners have had to pay VED for the first time, closing a loophole that had existed since VED was introduced. The direction of travel is clear: as the vehicle fleet becomes more electrified, the tax system is being adjusted to ensure everyone contributes, whatever they drive.

The Legal and Regulatory Framework

VED is governed primarily by the Vehicle Excise and Registration Act 1994, with the specific bands and rates set out in secondary legislation and updated through annual Budget statements or Finance Acts. The system that links first-year rates to CO2 emissions was introduced in 2017 and has been tweaked repeatedly since, including the introduction of the Expensive Car Supplement, an additional annual charge for vehicles with a list price over £40,000, payable for several years after registration.

It's worth stressing that VED is a legal requirement, not an optional extra. Keeping a vehicle on a public road without valid tax (unless it's formally declared off-road with a Statutory Off Road Notification, or SORN) is a criminal offence, and the DVLA has increasingly sophisticated enforcement tools, including Automatic Number Plate Recognition cameras, to catch untaxed vehicles. Penalties for non-payment can escalate quickly, from a fixed penalty notice through to court action and, in persistent cases, vehicle clamping or seizure. If you're ever unsure about your vehicle's tax status, checking directly through the official gov.uk vehicle tax checker is the safest route, rather than relying on assumptions from a previous renewal.

The Treasury's involvement in confirming these changes, rather than leaving it to DVLA administrative updates, reflects that VED remains a fiscal policy tool as much as a motoring administration matter. Changes of this scale typically go through Parliamentary scrutiny as part of the Finance Bill process, giving MPs the opportunity to raise constituent concerns, though the practical outcome for drivers rarely changes once the rates are set.

What Drivers Should Know and Do

If you're concerned about how these changes might affect you, there are some practical steps worth taking now rather than waiting for your renewal reminder to land.

Check your vehicle's emissions band. Your car's CO2 figure, found on your V5C logbook or via the DVLA's online vehicle enquiry service, determines which VED band you fall into. Understanding where your car sits helps you anticipate roughly how much of an increase you're likely to see.

Factor tax into any new car purchase decisions. If you're shopping for a new petrol or diesel vehicle in the run-up to April 2026, the first-year rate could be a significant and unavoidable part of the on-the-road price, particularly for larger or more powerful models. It's worth asking dealers to confirm the exact first-year VED figure before you commit, rather than discovering it buried in the paperwork later.

Don't assume electric means exempt. Since the April 2025 changes, EVs are no longer free from VED, so if you're weighing up switching to electric partly on the assumption of ongoing tax exemption, that calculation has already shifted.

Set up a direct debit and keep your details current. Given rates are rising, it's worth double-checking that your DVLA record has your correct address and that any direct debit arrangement will simply update to the new rate automatically, avoiding an accidental lapse in cover.

If you're selling or buying privately, confirm the tax situation clearly. VED isn't transferable between owners, so buyers need to tax the vehicle themselves from the point of purchase. Getting this wrong, even briefly, can leave you exposed to enforcement action.

Looking Ahead

This latest increase is unlikely to be the last word on vehicle taxation reform. With the government continuing to grapple with how to replace lost fuel duty revenue as the vehicle fleet electrifies, alongside ongoing discussion around pay-per-mile style road pricing, VED changes of this kind are likely to keep appearing in future Budgets. For now, the practical takeaway for drivers is simple: check your figures early, don't get caught out by a higher-than-expected renewal notice, and if you're in the market for a new petrol or diesel car, make sure the first-year tax charge is part of your budgeting from the outset.

As with all tax matters, if you're uncertain how a specific change applies to your circumstances, the DVLA's official guidance or a qualified motoring finance adviser will give you the clarity that a headline figure alone cannot.
