A Polestar 4 salary sacrifice lets a UK higher-rate taxpayer run one of the more interesting premium EVs on sale for a net monthly cost that a personal lease cannot match, because the electric-car benefit-in-kind rate is still only 4 per cent for 2026/27. The Polestar 4 is the rakish, fast, long-range electric coupe-SUV famous for deleting its rear window, and on payroll the maths is genuinely compelling. Here is how the sums work, the Single Motor versus Dual Motor decision, and the quirks worth understanding before you sign.
What a Polestar 4 sal-sac actually costs
As with any electric salary-sacrifice car, the saving comes from avoiding income tax and national insurance on the sacrificed salary, while the tax on the car itself stays tiny thanks to the 4 per cent rate. We read the rate from the HMRC schedule and worked the figures below from Polestar UK list pricing; always re-run them on your exact P11D and scheme quote.
- EV BiK rate 2026/27: 4 per cent, per HMRC’s appropriate-percentage tables (checked 31 May 2026).
- Range on tap: the Long Range Single Motor is rated for well over 350 miles, easing the charging routine.
- Cost lever: the Single Motor’s lower P11D makes it cheaper in benefit-in-kind and usually in monthly sacrifice than the Dual Motor.
How a Polestar 4 salary sacrifice puts the EV within reach
Salary sacrifice works by having your employer lease the car while you give up a slice of gross pay to fund it. Because that sacrifice happens before income tax and national insurance, a higher-rate employee effectively buys the lease at close to 42 per cent off, before the small benefit-in-kind charge is added. On a car like the Polestar 4, which lists in genuinely premium territory, that gross-pay mechanism is what turns an expensive EV into an affordable monthly figure, and it is why sacrifice suits a £60,000 EV far better than a personal lease ever could.
The usual guardrail applies: the sacrifice cannot push your gross pay below the National Minimum Wage, so a £60,000-plus car on a modest salary may be capped. The saving is also at its largest for higher and additional-rate taxpayers, where the income-tax relief is 40 or 45 per cent rather than 20.
The benefit-in-kind sum on an electric Polestar
The tax you pay on the car is its P11D value times the appropriate percentage times your marginal rate. For a zero-emission car that percentage is 4 per cent in 2026/27 per HMRC’s company-car tax guidance, rising to 5 per cent in 2027/28, 7 per cent in 2028/29 and 9 per cent in 2029/30. We quote these from the official schedule rather than memory because Budgets move them, and you should confirm the figure for your start year. Even at the top of that path, the Polestar 4’s company-car tax is a rounding error next to an equivalent petrol performance car.
Single Motor or Dual Motor: the P11D decision
The Polestar 4 comes as a rear-drive Long Range Single Motor and a much more powerful all-wheel-drive Long Range Dual Motor. The Single Motor is the value choice on sacrifice: it has the lower P11D, the longer official range, and more than enough pace for the school run and the motorway. The Dual Motor is seriously quick but its higher P11D pushes up the benefit-in-kind and usually the monthly cost. Our view is to take the Single Motor unless you specifically want the performance, because on payroll you pay for that bigger P11D every month for the life of the agreement.
A worked example on a Polestar 4 Long Range
Say the Single Motor carries a P11D of about £60,000 (use Polestar UK’s current figure for your spec and options). At 2026/27’s 4 per cent rate, the taxable benefit is £2,400 a year, so a higher-rate taxpayer pays £960 of benefit-in-kind tax annually, around £80 a month, on the car. That is the whole company-car tax bill on a £60,000 EV. The headline saving then comes from funding the lease out of gross salary, sparing a higher-rate employee 40 per cent income tax and 2 per cent national insurance on that money, which is what drops the true net cost beneath a comparable personal lease with insurance and maintenance added in.
| Polestar 4 Single Motor BiK (P11D ~£60,000, 4%) | Taxable benefit | BiK tax |
|---|---|---|
| Basic-rate (20%) taxpayer | £2,400/yr | £480/yr (£40/mo) |
| Higher-rate (40%) taxpayer | £2,400/yr | £960/yr (£80/mo) |
| Additional-rate (45%) taxpayer | £2,400/yr | £1,080/yr (£90/mo) |
The no-rear-window question and what is in the scheme
The Polestar 4’s signature party trick is the deleted rear window, replaced by a roof-mounted camera feeding a digital rearview mirror. In practice most owners adapt quickly and enjoy the airy, lounge-like rear cabin it allows, but it is worth a test drive to be sure it suits you, because it is the one thing about this car people react strongly to. On the scheme itself, check what is bundled: most premium salary-sacrifice packages include insurance, maintenance, tyres and breakdown, plus often a home charger or charging credit. Pin down the mileage allowance, the excess rate, and the early-exit terms. If you are cross-shopping rivals, our Tesla Model 3 salary sacrifice and BMW i4 salary sacrifice guides run the same maths, and our Polestar 2 salary sacrifice guide covers the cheaper sibling.

What to nail down before you order a Polestar 4
Settle these before you place the order:
- Confirm the EV benefit-in-kind rate for your start tax year on the HMRC tables, not an old figure.
- Get the exact P11D for your chosen Single Motor or Dual Motor spec from Polestar UK and recompute the BiK.
- Test the digital rearview mirror and rear visibility on a real drive to be sure the no-window layout suits you.
- Ask what happens on early exit if you leave the employer, and the size of any termination charge.
- Check whether insurance, maintenance, tyres and a home charger are included, plus the mileage limit and excess rate.
- Confirm the sacrifice keeps your gross pay above the National Minimum Wage on a car of this price.
The CDE verdict
For a UK higher or additional-rate taxpayer who wants something more distinctive than the obvious German and Tesla choices, a Polestar 4 salary sacrifice is a genuinely smart move in 2026. The 4 per cent rate keeps the company-car tax to around £80 a month for a higher-rate driver on a £60,000 EV, the gross-pay sacrifice strips income tax and NI off the lease, and you get a fast, long-range, beautifully finished car into the bargain. We would take the Single Motor for the best balance of range, P11D and monthly cost, drive the no-rear-window layout before committing, and read the early-exit clause closely. The buyers who should pause are those whose salary brings the National Minimum Wage floor into play, and anyone who cannot live with the camera mirror. For everyone else, this is one of the most appealing sal-sac cars on sale.
