Polestar 4 on salary sacrifice in 2026: the higher-rate taxpayer’s verdict

I’ve spent the past fortnight running the numbers on the Polestar 4 because a reader emailed me a screenshot of a quote and asked, quite reasonably, whether it was too good to be true. The figure I keep coming back to, which lines up with Polestar’s own salary sacrifice pages as of June 2026, is a Long Range Single Motor landing at roughly £446.76 a month net for a 40% taxpayer. That is the sort of number that makes people do a double-take, and it deserves a proper, sceptical look rather than a cheer.

What you’re actually agreeing to pay (salary sacrifice)

Let me put the two variants side by side, because the gap between them is where most of the decision sits. The Long Range Single Motor (94kWh, a 305-mile WLTP range and 0-62mph in 7.4 seconds) quotes at £746 a month gross. After income tax and National Insurance relief, and once you’ve absorbed the benefit-in-kind charge, that comes down to £446.76 a month for a higher-rate taxpayer. Step up to the Dual Motor (same 94kWh battery, but a shorter 285-mile range because the second motor is thirsty) and the gross is £824, netting £493.18.

One caveat before we go further: these are illustrative figures, not a finance offer. Salary sacrifice isn’t a credit agreement, but the net numbers still hinge on your own salary, tax code and your employer’s specific scheme, so treat everything here as a worked example built on the published 2026 quotes and the 2026/27 tax rates, and read any real quote as subject to status. Your own figure will differ.

So the real-world difference between the two is about £46 a month. For that you get meaningfully more performance and meaningfully less range. I’ll come back to why that trade-off matters, but hold the thought: you are paying more, every month, for a car that goes less far on a charge.

Why the net figure is so much lower than the sticker

The mechanism here isn’t magic, and I think it’s worth understanding rather than just trusting. With salary sacrifice you give up gross salary in exchange for the car, so you never pay income tax or NI on the money that funds the lease. As SalaryTax sets out, a higher-rate taxpayer sacrificing £500 a month saves around £200 in income tax plus £10–£25 in NI. The only clawback is the benefit-in-kind charge on the car itself.

And on an EV that charge is currently tiny. The BiK rate is 4% in 2026/27. On the Polestar 4’s P11D value of £59,990, 4% is a taxable benefit of about £2,400 a year, so a 40% taxpayer hands roughly £960 of that back to HMRC, somewhere around £80 a month. Net it all off and, as the Electric Car Scheme explains, higher-rate taxpayers typically come out 40–50% cheaper than a personal lease, often £175–£195 a month better off on a car of this size.

The rising BiK is the bit I’d plan around

Here is what stops me treating that 4% as permanent. The rate is legislated to climb: 5% in 2027/28, 7% in 2028/29, and 9% in 2029/30. None of that is a rumour: it’s pre-announced HMRC policy, and the rest of the salary sacrifice framework is, by every account I can find, unchanged for 2026 with no caps or restrictions bolted on.

What that means in practice is that your BiK bill more than doubles over a typical lease. At 4% you’re paying roughly £80 a month in tax on the benefit; at 9% on the same P11D you’re closer to £180. That’s an extra £100 a month creeping in by 2029/30, not enough to wreck the deal, but enough that the headline net figure you sign up to in 2026 is the best month you’ll ever have. If you’re being sold on £446.76, mentally pencil in a number that drifts upward each April.

Single Motor or Dual Motor?

For salary sacrifice specifically, I’d take the Single Motor almost every time, and the reasoning is unglamorous. You’re already getting the performance subsidised by the tax relief, so the £46-a-month premium for the Dual Motor buys you acceleration you’ll rarely use while costing you 20 miles of range you’ll genuinely miss in winter. A 305-mile WLTP figure realistically becomes something closer to 230–240 in cold weather on a motorway; lop 20 off that and the Dual Motor starts to feel like a car you plan journeys around. The Single Motor is the one I’d actually live with.

Who this works for, and who should walk away

This is a genuinely strong deal for a specific person: a 40% taxpayer, in stable employment, whose employer already runs a scheme, who can commit to the full term, and who has somewhere to charge at home or work. If that’s you, the Polestar 4 Single Motor at sub-£450 net is one of the better large-EV propositions I’ve looked at this year, and it’s worth comparing the indicative market lease pricing for the same spec at an independent broker such as UK Carline to see how a personal lease compares, remembering any salary sacrifice arrangement runs through your own employer’s scheme provider rather than a broker.

But I’d tell three groups to think harder. If you’re a basic-rate taxpayer, the savings are real but far less dramatic: the maths leans much more on the 40% relief than people assume. If there’s any chance you’ll leave the job mid-term, understand your scheme’s early-exit terms before you fall for the monthly figure, because salary sacrifice cars can be expensive to hand back early. And if salary sacrifice would drag any of your income below the National Minimum Wage, you simply can’t do it, and a £446 sacrifice is not trivial against a modest salary.

The honest bottom line

I came to this expecting to find a catch, and the catch is just time: the deal is excellent today and quietly less excellent every year as BiK climbs to 9%. That’s not a reason to avoid it: it’s a reason to go in with your eyes open and treat the 2026 net figure as a ceiling on value, not a floor. If I were a higher-rate taxpayer with a charger on the drive and a scheme on offer, I’d take the Long Range Single Motor and I’d do it sooner rather than later, precisely because the 4% window is the cheapest this car will ever be to run. The one thing that would change my mind is job uncertainty: if my role felt shaky, no monthly saving would be worth being locked into a four-figure gross sacrifice I might have to unwind early.
