The 2028 Hybrid Tax Trap: Bringing Clarity to Your Next Company Car Decision
The 2028 Hybrid Tax Trap: Bringing Clarity to Your Next Company Car Decision
We are increasingly being asked whether buying or leasing a hybrid car through a limited company still makes financial sense.
For several years, plug-in hybrids (PHEVs) have been a popular, tax-efficient choice for company directors, offering low Benefit-in-Kind (BiK) tax rates, corporation tax relief and flexibility for longer journeys.
However, changes to HMRC rules mean the tax advantages of hybrid vehicles are set to reduce significantly over the next few years.
If you’re considering your next company car, it’s worth understanding what’s changing and how it could affect your decision.
The Four-Year BiK Outlook: The 2028 Cliff Edge
Currently HMRC rewards long-range plug-in hybrids. If your PHEV has CO2 emissions under 50g/km and a high electric-only range, your personal BiK rate is kept low, closely matching a pure electric vehicle (EV).
From 6 April 2028 this range protection disappears entirely. HMRC is scrapping the electric-range brackets for all company cars emitting between 1–50g/km. Instead, every single plug-in hybrid will be moved onto a steep, flat mandatory rate.
This is how the BiK percentages look over the next four tax years:
What this means for your cash flow
If you enter into a standard three or four-year lease on a premium £50,000 long-range plug-in hybrid today, you will hit this tax wall right in the middle of your agreement.
- For you personally: As a 40% higher-rate taxpayer, your personal annual tax bill for that car will jump from around £800 this year to £3,600 by 2028/29.
- For your business: Your limited company’s Class 1A National Insurance contribution on that benefit will rise from £300 to £1,350 per year.
Corporate Tax relief: Capital allowances
The rules for writing off the cost of the vehicle against your company’s taxable profits also look very different depending on what you drive:
- Pure EVs: Brand new electric cars attract a 100% First-Year Allowance (FYA). Your business can deduct the entire purchase price from taxable profits on day one, reducing your Corporation Tax bill straight away.
- Hybrids (1–50g/km): These do not qualify for the upfront deduction. They sit in the Main Pool, meaning the company can only write off 18% of the remaining value each year.
- Standard Hybrids (Over 50g/km): These are restricted to the Special Rate Pool, giving you a slow 6% deduction annually.
Which tax savings are still available for hybrids?
If you genuinely prefer a hybrid or your mileage patterns mean an EV isn't practical, it is still possible to claim some tax relief through the business:
- Running Costs: The company can pay for and fully offset all legitimate running expenses, including business motor insurance, repairs, servicing, road tax, and breakdown cover, against its Corporation Tax.
- VAT on Leases: While you cannot usually reclaim VAT if you buy a company car outright, if you lease a hybrid, you can reclaim 50% of the VAT on your monthly finance payments, even with private use.
Our advice: How to plan ahead
If your priority is pure tax efficiency, a fully electric vehicle remains the clear winner under current HMRC rules.
If you have your heart set on a petrol hybrid, running it through a limited company is rapidly becoming an expensive option. For many of our clients it is now far more practical and cost-effective to take profits from the business via dividends, buy or lease the hybrid personally and then have the company pay you the statutory tax-free mileage rate of 45p per mile for your business travel.
