What is a cash allowance?
A cash allowance is a set amount of money your employer offers instead of a company car. You receive the cash as part of your salary, and it’s yours to spend however you choose — including leasing, buying, or running your own car.
Key characteristics
- Paid as part of your net salary
- No tax advantages on the allowance itself
- Freedom to choose any vehicle or none at all
A cash allowance might seem simple, but the full cost to you depends on how you spend it — particularly after tax.
What is salary sacrifice?
Salary sacrifice is an arrangement where you give up part of your gross (pre-tax) salary in return for a benefit — often a company car. In 2026, salary sacrifice is especially effective for electric vehicles due to low Benefit-in-Kind (BiK) tax rates.
Key features
- Gross salary is reduced
- Income tax and National Insurance are calculated on lower income
- Often includes insurance, servicing, and maintenance
The tax savings are a major part of the benefit, particularly for higher-rate taxpayers.
Tax implications of each
Understanding how each option interacts with tax is essential when comparing real cost.
Cash allowance tax treatment
- Treated as taxable income
- Subject to income tax and National Insurance
- No additional tax benefit
Salary sacrifice tax treatment
- Reduces gross salary before income tax and NI
- BiK tax applies to company car benefit
- Net cost often lower than cash allowance spent on a personal lease or purchase
The result? Salary sacrifice usually reduces your effective tax bill compared with taking a cash allowance and spending it separately.
Cost comparison examples
Let’s compare how the real costs can differ when choosing salary sacrifice versus cash allowance options.
Scenario: Electric car preferred
- Salary sacrifice may reduce taxable income and NI
- Electric cars have very low BiK rates, lowering tax even further
- Cash allowance must cover lease, insurance, maintenance, and running costs after tax
In many cases, spending a cash allowance on a personal lease or purchase can end up costing more monthly than using a well-structured salary sacrifice scheme for the same vehicle.
Which option is better?
There’s no universal answer — it depends on your tax band, how much your employer offers as a cash allowance, and whether you want a new car.
Salary sacrifice tends to be better if:
- You are a higher-rate or additional-rate taxpayer
- You want an electric or plug-in hybrid car
- Your employer’s salary sacrifice scheme includes insurance and maintenance
Cash allowance may be better if:
- You prefer complete control over the car you choose
- You plan to use the cash allowance for non-car expenses
- Your tax situation doesn’t make salary sacrifice advantageous
Either way, calculating the real cost — including tax, running costs, deposit, and monthly charges — helps you decide objectively.
