Use this NHS lease car tax calculator to find out exactly how much Benefit-in-Kind (BIK) tax you will pay on a lease car through the NHS salary sacrifice car scheme. Enter your NHS pay band, the car's P11D value, CO₂ emissions, and lease term. The calculator returns your monthly BIK tax charge, your Income Tax and National Insurance savings, your pension contribution impact, and your true net monthly cost — calculated using HMRC-confirmed rates for the 2026/27 tax year.
NHS lease car tax is the Benefit-in-Kind (BIK) Income Tax charge that HMRC applies when your NHS employer provides you with a lease car as part of a salary sacrifice arrangement. 7Salary sacrifice cars are considered company cars by HMRC, classed as a non-cash benefit, and employees who have a salary sacrifice car pay company car tax — also known as Benefit-in-Kind (BIK).
The BIK charge exists because HMRC treats the private use of a lease car as additional income. 7The amount of company car tax you pay depends on the vehicle's CO₂ emissions, P11D value, and your personal tax rate.
The BIK tax is not deducted directly from your payslip as a line item. Instead, 4your company car benefit is reported on your tax code — check your code to confirm the right amount is being taxed. HMRC adjusts your personal allowance downward so that the tax is collected automatically through PAYE across the remaining months of the tax year.
Three inputs determine how much BIK tax you pay each year:
Input 1 — P11D Value: 2For company car tax, P11D value normally means the manufacturer list price when new, including VAT, delivery, and relevant accessories. It is not usually the discounted price, used-car value, or lease rental.
Input 2 — CO₂ Appropriate Percentage: 7BIK rates are set by the Government and can change each tax year. The appropriate percentage is a number assigned by HMRC to each CO₂ emissions band. The lower the emissions, the lower the percentage, and the lower the tax.
Input 3 — Your Marginal Income Tax Rate: 7The amount you pay will also change if you move into a different income tax band — for example, if you receive a company car as a 20% taxpayer and later move into the 40% tax bracket, the tax payable on your Benefit-in-Kind will increase accordingly.
The BIK tax formula is:
Annual BIK tax = P11D value × CO₂ appropriate percentage × your marginal Income Tax rate
Monthly BIK tax = Annual BIK tax ÷ 12
The calculator performs five calculations in sequence and returns all results instantly.
Step 1 — BIK Taxable Value Multiplies the car's P11D value by the HMRC CO₂ appropriate percentage for the 2026/27 tax year.
Step 2 — Annual and Monthly BIK Tax Applies your marginal Income Tax rate (20%, 40%, or 45% in England, Wales, and Northern Ireland; Scottish rates applied automatically for Scottish tax codes) to the BIK taxable value.
Step 3 — Income Tax Saving from Salary Sacrifice Calculates the Income Tax you no longer pay because the lease deduction reduces your gross taxable pay before PAYE is applied.
Step 4 — National Insurance Saving Calculates the employee Class 1 NI you save on the sacrificed salary. The employee NI rate is 8% on earnings between £12,570 and £50,270, and 2% above £50,270 for 2026/27.
Step 5 — True Net Monthly Cost Combines all four outputs into one definitive number:
Net monthly cost = Gross monthly lease payment − Monthly Income Tax saving − Monthly NI saving + Monthly BIK tax
11 For a 20% taxpayer, a £100 car lease deduction might only reduce actual take-home pay by roughly £70 to £80, depending on the NI bracket. For those in the higher 40% tax bracket, typically Band 8b and above, the savings are even more pronounced.
5 Company car BIK appropriate percentages rose by 1 percentage point for most bands from 6 April 2026 under the published HMRC schedule — a fully electric car is 4% in 2026/27, up from 3% in 2025/26, rising 1 percentage point per year to 9% by 2029/30, with the overall cap staying at 37%.

8 For salary sacrifice electric cars, Benefit-in-Kind is only 4% in 2026/27, rising slowly to reach 9% in 2030. With petrol cars starting at more than 25% Benefit-in-Kind, there are considerable tax savings when choosing an ultra-low emission car.

15 Salary sacrifice is when a portion of your gross (pre-tax) salary is exchanged for a benefit — in this case a leased vehicle. This can reduce your taxable income, which can reduce your Income Tax and National Insurance. 13 You pay for the lease from your salary before Income Tax and National Insurance are taken off, so you save the tax you would have paid on the lease. You give up part of your salary before tax each month, and in return your employer gives you a non-cash benefit — in this case, a new car of your choice.

14 A 40% taxpayer sacrificing £400 monthly saves £160 in income tax plus £48 in NI, making the true cost £192 instead of £400. Higher-rate NHS taxpayers (Band 8a and above) receive the largest proportional savings from the salary sacrifice mechanism.
The Optional Remuneration Arrangement (OpRA) rule, introduced by HMRC on 6 April 2017, changed how BIK tax is calculated for salary sacrifice cars. 3Employees who have the option of a cash allowance or company car will pay tax on the higher of the benefit on the car or the cash allowance amount.
For NHS salary sacrifice, OpRA means the taxable BIK is the higher of:
Practical example of OpRA on an electric car:
Without OpRA, the BIK tax would be £1,600 × 20% = £320/year. OpRA increases the tax liability on EVs, but the NI saving, the fully inclusive package value (insurance, servicing, road tax, breakdown cover), and the ultra-low running costs still make EVs the most tax-efficient option in the NHS scheme for the majority of staff.
Ultra-low emission vehicles (ULEVs) with CO₂ of 75 g/km or below that were registered before 6 April 2017 are exempt from OpRA. All NHS Fleet Solutions cars ordered today are subject to OpRA.
13 You make savings via salary sacrifice — by paying less tax, you pay less overall than if you had leased a car yourself privately. With NHS Fleet Solutions there is much more included in your monthly cost: insurance (for you and up to 4 additional drivers), road tax, routine servicing, breakdown cover, tyre cover, and windscreen cover. 12 The scheme enables you to drive a brand new car of your choice with all the main running costs — such as servicing and maintenance, insurance, road tax, breakdown and recovery — included in a fixed monthly amount which is paid through salary sacrifice.
No deposit is required at any point. 13NHS Fleet Solutions offers 24- and 36-month contracts. 15If you decide to take on an NHS salary sacrifice car through the scheme every time your term ends, you can get a brand new vehicle, which is usually every 2 to 4 years.
If you choose a fully electric vehicle, 13opting for a fully electric car means you also have the option of adding a home charging point to your order, which you would also pay for via monthly salary sacrifice.
12 The salary sacrifice car scheme saves you money on tax and NI contributions, but can have an impact on your pension or benefits, which you should consider before applying. 10 Salary sacrifice can affect pension contributions, statutory payments, mortgage affordability assessments, and other salary-linked benefits.
Under the 2015 NHS Pension Scheme (CARE), your pension accrues at 1/54th of your pensionable earnings each year. 11The most significant hidden cost of a salary sacrifice in the NHS is the impact on your NHS Pension. In the 2015 CARE (Career Average Revalued Earnings) scheme, your pension is built up based on 1/54th of your pensionable earnings.
A salary sacrifice of £400/month (£4,800/year) reduces annual pensionable pay by £4,800.
Pension accrual lost per year of sacrifice: £4,800 ÷ 54 = £88.89 less annual pension added in that year
Over a 3-year lease: £88.89 × 3 = £266.67 less annual pension in retirement
Over a 20-year retirement (retirement at 67, life expectancy 87): £266.67 × 20 = £5,333 total pension income lost from one 3-year lease
14 Salary sacrifice reduces gross pensionable income. NHS pension contributions calculate on post-sacrifice salary. A £370 monthly sacrifice reduces annual pensionable income by £4,440. Over 30 years, this compounds into £45,000–£60,000 in reduced pension pot. Short-term leasing (3–4 years) minimises the impact.
The pension impact is modest for most Band 2–7 staff on short lease terms. The risk is highest for:
If you are a high earner, HMRC will restore your full salary when the lease ends. This salary increase can cause a pension growth spike that breaches the Annual Allowance, triggering an unexpected tax charge. Seek independent financial advice if you earn above £75,000 before committing to a lease.
Scotland operates its own Income Tax system with six bands, and your BIK tax calculation changes accordingly.
Scottish Band | Rate | Threshold 2025/26 |
Personal Allowance | 0% | Up to £12,570 |
Starter Rate | 19% | £12,571 – £14,876 |
Basic Rate | 20% | £14,877 – £26,561 |
Intermediate Rate | 21% | £26,562 – £43,662 |
Higher Rate | 42% | £43,663 – £75,000 |
Advanced Rate | 45% | £75,001 – £125,140 |
Top Rate | 48% | Over £125,140 |
Disclosure: The thresholds above are 2025/26 figures published by Revenue Scotland. The 2026/27 Scottish thresholds should be verified at revenue.scot once confirmed.
A Band 7 nurse in Scotland earning £46,148 pays 42% (Scottish Higher Rate) on a portion of income — not the 20% English basic rate. The BIK tax formula remains the same, but the tax rate applied is higher, making electric cars even more financially advantageous for Scottish higher-rate taxpayers relative to petrol alternatives.
The calculator on this page automatically detects and applies Scottish Income Tax rates for tax codes beginning with "S".
These are two distinct arrangements with different eligibility criteria and tax treatments. Understanding the difference is essential before calculating your true cost.
Feature | NHS Business Lease Car | NHS Salary Sacrifice Car |
Eligibility | Staff travelling 1,000+ business miles/year | All permanent NHS staff (Trust-dependent) |
Payment mechanism | Deducted from gross pay | Salary sacrifice from gross pay |
BIK tax charged? | Yes — P11D × CO₂ % | Yes — higher of BIK or salary sacrificed (OpRA) |
Business mileage reimbursement | Yes — at HMRC advisory fuel rates, tax-free | No — all miles treated as personal |
Pension impact | Yes — reduces pensionable pay | Yes — reduces pensionable pay |
Insurance included? | Yes | Yes |
Ownership at end of term | No — return the vehicle | No — return the vehicle |
The key distinction on tax is business mileage reimbursement. NHS staff with 1,000 or more business miles per year receive tax-free mileage payments under the business lease arrangement. Under salary sacrifice, all mileage is personal and no HMRC fuel rate reimbursement applies.
12 In partnership with scheme providers, all permanent members of staff at participating NHS Foundation Trusts are able to lease a vehicle through salary sacrifice. 10 The general process is simple. Eligible staff register through the official scheme, browse available vehicles, choose a car, and submit an application. Once approved by the employer and scheme provider, the order is processed and the vehicle is delivered when available. Lease terms often run for two or three years. At the end of the agreement, the employee usually returns the car and may choose another vehicle if they remain eligible. 15 Staff must work for a company that participates in the salary sacrifice scheme and must earn enough that the deductions from their salary do not take them below minimum wage — £30,000 annual salary is the lowest considered for salary sacrifice by many providers.
NHS Fleet Solutions 13is the UK's original and largest public sector salary sacrifice scheme, currently providing the scheme to over 300 organisations.
5 Your personal allowance is effectively reduced by the P11D value, meaning you pay more tax through PAYE each month. For example, if your P11D benefits total £5,000 and you are a 40% taxpayer, HMRC will collect an extra £2,000 over the year through your reduced tax code — roughly £167 per month less in your take-home pay. Your employer reports the car on form P11D. HMRC issues a revised tax code and collects the charge automatically through your payslip.
4 Pure electric vehicles have a BIK rate of just 3% for 2025/26, making them significantly cheaper to run as company cars than petrol or diesel equivalents. The rate is scheduled to rise gradually: 4% in 2026/27 and 5% in 2027/28, still well below combustion engine rates.
The calculation is: £35,000 × 4% × your tax rate.
Yes — higher-rate taxpayers receive the greatest salary sacrifice savings. 14A 40% taxpayer pays £192 net monthly with salary sacrifice versus £300+ for personal leasing. However, the pension impact is proportionally larger for high earners, and the Annual Allowance risk must be assessed before signing.
Yes. 11For the 2026/27 financial year, it is more important than ever to understand how salary sacrifice deductions interact with pensionable pay. Because salary sacrifice reduces your headline salary, it can have a ripple effect on your future retirement benefits, your maternity entitlements, and even your mortgage affordability. Most mortgage lenders calculate affordability on your post-sacrifice gross salary. Declare the sacrifice arrangement to your mortgage adviser before applying.
10 The main risks relate to long-term affordability, employment changes, mileage limits, and the effect on salary-related benefits. Early termination is generally not permitted unless you experience a qualifying life event — such as redundancy, long-term sick leave, or maternity leave. Early exit charges apply in most cases. Review the full contract terms before ordering.
The BIK tax itself does not change — it is tied to the car's P11D value and CO₂ emissions, not your employer. However, moving Trust may affect the salary sacrifice arrangement. Your new Trust must participate in the same scheme. If they do not, the lease contract may need to be terminated early, incurring charges.
12 The salary sacrifice car scheme can have an impact on your pension or benefits, which you should consider before applying. During maternity leave, your statutory maternity pay is calculated on your post-sacrifice salary. If your maternity pay falls below the monthly lease deduction, you may need to cover the shortfall from your own savings. Confirm the maternity pay implication with your NHS Trust's payroll team before leasing.
11 If you choose a high-emission petrol or diesel car, the Benefit-in-Kind tax can often outweigh the salary sacrifice savings. This is why many NHS staff are moving toward ultra-low emission vehicles or electric vehicles, which currently attract significantly lower Benefit-in-Kind rates for the 2026/27 tax year. For most NHS staff at Band 5–7, a petrol car emitting 120+ g/km produces a BIK tax charge that eliminates all Income Tax and NI savings from the salary sacrifice, resulting in no net benefit.
13 When you return your car, your salary goes back to normal. 10 At the end of the agreement, the employee usually returns the car and may choose another vehicle if they remain eligible. You are responsible for returning the vehicle within the agreed mileage limit and in fair condition. Excess mileage charges and damage charges apply at the provider's published rates. You receive notification approximately 6 months before the contract end date to begin selecting a replacement vehicle.
