Salary Sacrifice Car vs Car Loan or PCP 2026/27

Written and reviewed by James Whitfield. Last updated for the 2026/27 tax year.

Quick answer — 2026/27

For a new electric car, salary sacrifice is usually cheaper than a personal car loan or PCP because the lease comes out of gross pay — you save income tax (20%, 40% or 45%) and employee NI (8% or 2%) on it, and pay only 4% Benefit-in-Kind tax on the car in 2026/27. A car loan or PCP is paid from net income with no tax relief. Salary sacrifice also usually bundles insurance, servicing, tyres and breakdown into one figure. A loan or PCP tends to win only for a petrol or diesel car (where the BIK charge is far higher), a cheap used car, or if you value owning the vehicle at the end.

"Should I get the car through salary sacrifice or just take out a loan?" is one of the most common questions about EV schemes. The honest answer depends on the type of car and your tax rate. This guide walks through how each option is taxed, a worked comparison for a higher-rate taxpayer, and the situations where a loan or PCP actually comes out ahead.

How each option is taxed

Salary sacrifice (electric car)

Your employer leases the car and you give up part of your gross salary to cover it. Because the sacrifice reduces your contractual pay, you never pay income tax or National Insurance on that money. In exchange, the car is a Benefit in Kind: for a fully electric (zero-emission) car the taxable percentage is 4% of the P11D value in 2026/27 (rising to 5% in 2027/28). You pay income tax on that small BIK figure at your marginal rate.

Income tax saved on the sacrifice: 20%, 40% or 45% depending on your band.
Employee NI saved on the sacrifice: 8% between £12,570 and £50,270, or 2% above.
BIK tax owed: 4% × P11D value, taxed at your marginal rate.
Insurance, servicing, tyres, breakdown cover and road tax are normally included in the monthly figure.

Personal car loan or PCP

You borrow the money (or finance it through PCP) and repay from your take-home pay — income that has already been taxed and had NI deducted. There is no BIK, because you own or are buying the car personally, but there is also no tax relief. You arrange and pay for insurance, servicing, tyres and road tax yourself, on top of the finance.

Worked comparison — higher-rate taxpayer, £40,000 electric car

Take a 40% taxpayer choosing a £40,000 (P11D) electric car. The salary-sacrifice scheme quotes £500 a month gross (£6,000 a year), fully maintained and insured. The figures below are illustrative — your own quote, P11D value and tax band will change the result.

Gross sacrifice: £6,000 a year.
Tax + NI saved: 42% × £6,000 = £2,520, so the net cost of the sacrifice is about £3,480 a year (£290/month).
BIK tax: 4% × £40,000 = £1,600 taxable benefit × 40% = £640 a year (about £53/month).
Total net cost: roughly £4,120 a year, or about £343 a month — for a brand-new EV with insurance, servicing and tyres included.

To match that on a personal loan or PCP, you would need finance plus insurance, servicing and tyres for under about £343 a month from your take-home pay — difficult on a new £40,000 EV, especially once fully-comprehensive insurance is added. For a new electric car, salary sacrifice usually wins clearly for higher-rate taxpayers, and still helps at basic rate (where you save 28% rather than 42%).

When a car loan or PCP wins

Petrol or diesel cars. Salary sacrifice tax savings are largely wiped out by the much higher BIK on non-electric cars (which can be 25–37% of P11D). For a petrol or diesel car a loan or PCP is usually cheaper.
Cheap or used cars. Sacrifice schemes are built around new leases. For a modest used car, a small loan repaid from net pay can cost less overall.
You want to own the car. With salary sacrifice you hand the car back at the end; with a loan (or PCP with a final payment) you can keep it.
You may leave your job. Early-exit charges can apply if you leave mid-lease — a personal loan stays with you regardless of employer.
Low earners. The sacrifice must not take your cash pay below the National Minimum Wage, which can limit or block the scheme.

Other things to weigh up

Salary sacrifice lowers your contractual salary, which can affect mortgage affordability assessments and any salary-linked benefits (life cover, statutory maternity pay). A car loan or PCP has no effect on your stated salary but is a personal debt that a lender will see on a credit check. Both belong in the decision, not just the monthly cost.

Frequently asked questions

Is salary sacrifice cheaper than a car loan?

For a new electric car, usually yes — the lease is paid from gross salary, saving income tax and NI, and the Benefit-in-Kind charge is only 4% of the car's value in 2026/27. A loan or PCP is repaid from taxed income with no relief. For a petrol or diesel car, or a cheap used car, a loan is often cheaper because the BIK charge on non-electric cars is much higher.

Do I own the car with salary sacrifice?

No. Salary sacrifice is a lease arranged by your employer — you hand the car back at the end of the term. With a loan you own the car outright, and with PCP you can own it by making the optional final payment. If keeping the car matters to you, that favours a loan or PCP.

What happens to salary sacrifice if I leave my job?

The car is tied to your employment, so leaving mid-lease can trigger early-termination charges, depending on your scheme's rules. Some schemes include protection or an early-exit insurance option. Always read the exit clauses before signing. A personal loan or PCP is unaffected by changing jobs.

Does salary sacrifice for a car affect my mortgage?

It can. Salary sacrifice reduces your contractual gross salary, and many mortgage lenders assess affordability on the post-sacrifice figure. A car loan does not reduce your salary but appears as a monthly commitment and debt on your credit file. Both can influence how much you can borrow.
