Salary Sacrifice vs Salary Deduction: Choosing Between Them

In this guide, we’ll break down the difference between salary sacrifice and salary deduction, look at when each makes sense, and explain why salary sacrifice, particularly for electric cars, has become one of the most effective ways to offer a high-impact, cost-efficient benefit.

By the end, you should have a clear view of which approach fits your business, and why some benefits work far better when they’re built as proper schemes rather than simple deductions.

What is salary sacrifice?

Salary sacrifice is an agreement between you and your employer to swap part of your gross salary for a benefit.

Instead of being paid all your salary in cash, you agree to “sacrifice” a portion of it. In return, your employer provides something of value, like extra pension contributions, childcare, or in this case - an electric car.

That money is taken before tax and National Insurance are worked out.

So while your headline salary goes down on paper, your take-home pay often doesn’t fall by the same amount, because you’re paying less tax overall.

Here’s a simple way to think about it:

• You earn £X
• You agree to give up £Y in exchange for a benefit
• Your tax and NI are calculated on £X minus £Y

That’s what makes salary sacrifice different from just paying for something normally.

It’s commonly used for things like:

• Pension contributions
• Cycle to Work schemes
• Childcare (older schemes)
• Electric cars through salary sacrifice

Not every benefit is treated the same for tax, but when it’s set up properly, salary sacrifice can be a genuinely tax-efficient way to pay for something you were planning to pay for anyway.

What is salary deduction?

Salary deduction is when money is taken from your pay after tax has already been worked out. In other words, you’re paid your full salary first, tax and National Insurance are applied as normal, and then a deduction is made from your take-home pay to cover a cost.

There’s no special tax treatment here. It’s simply a way of paying for something through payroll.

A simple way to picture it:

• You earn £X
• Tax and NI are calculated on the full £X
• £Y is then deducted from what hits your bank account

Salary deductions are commonly used for things like:

• Union or professional membership fees
• Repaying a workplace loan
• Charity donations
• Gym memberships or other voluntary benefits

They’re often convenient because everything comes out automatically and you don’t need to set up separate payments. But financially, they work the same as paying for something yourself via direct debit.

That’s why salary deduction and salary sacrifice can feel similar when you hear the terms for the first time. Both reduce what you take home each month. But only one can reduce the amount of tax you pay in the first place - salary sacrifice.

Salary sacrifice vs salary deduction: What’s the difference?

The easiest way to understand the difference between salary sacrifice and salary deduction is to look at them side by side.

Key difference 1: How tax and National Insurance are treated

This is where the biggest difference between salary sacrifice and salary deduction shows up and why the two shouldn’t be confused.

With salary sacrifice, the cost of the benefit is taken from your pay before Income Tax and National Insurance are calculated. That means your taxable salary is lower, so you usually pay less tax and NI overall.

This is not some dodgy tax avoidance ploy. In fact, it's completely backed by the government as a way to incentivise certain schemes. You’re simply not paying tax on the part of your salary you’ve chosen to swap for a benefit instead.

With salary deduction, it works the other way around. Tax and National Insurance are calculated on your full salary first, and only then is the cost deducted from your take-home pay. From a tax point of view, it’s exactly the same as paying for something yourself by direct debit.

That’s why salary sacrifice can lead to meaningful savings, while salary deduction generally can’t.

This difference is especially important for electric cars. EVs benefit from very low Benefit-in-Kind (BIK) tax rates, which means you can reduce your taxable salary and only pay a small amount of tax on the benefit itself. 

Put simply:

• Salary sacrifice reduces the amount of your income that’s taxed
• EVs are taxed very lightly as a benefit

When those two things come together, the savings can be significant. loveelectric drivers, for example, save an average of £290/month on their lease cost. 

That is why many people find it’s the most cost-effective way to drive an electric car. 

There are also tax advantages on the employer side, including National Insurance savings, which help explain why EV salary sacrifice schemes are so widely offered.

Key difference 2: Effect on pensions and other benefits

This is where people often pause and think, “Hang on, could this affect my pension?”

It’s a fair question, and the answer depends on whether you’re using salary sacrifice or salary deduction.

With salary sacrifice, your contractual salary is technically lower. Because pension contributions are often calculated as a percentage of your salary, this can mean:

• Your own pension contributions are slightly lower
• Your employer’s contributions could also be lower

That said, many employers are well aware of this and choose to protect pension contributions by continuing to calculate them based on your pre-sacrifice salary. It’s very common, but not universal, so it’s always worth checking your scheme details with the provider and your employer.

With salary deduction, there’s no impact at all. Your salary on record doesn’t change, so pension contributions continue exactly as before.

A similar principle applies to other benefits that are linked to salary, such as:

• Maternity or paternity pay
• Sick pay
• Life assurance

Again, some employers base these on your pre-sacrifice salary, others don’t.

The important thing to remember is this: salary sacrifice doesn’t automatically reduce your pension or benefits. It just means they’re calculated differently, depending on how your employer has set things up.

If pensions or family-related benefits are a top priority for you, it’s worth asking a simple question before opting in: “Are my benefits based on my pre- or post-sacrifice salary?”

Clarity upfront avoids surprises later and helps you decide whether salary sacrifice is right for you at this stage.

Key difference 2: Minimum wage rules

One important rule applies to salary sacrifice, but not to salary deduction and it’s in regards to minimum wage.

When you use salary sacrifice, your pay is reduced before tax. Because of that, the law states that your salary cannot be reduced below the National Minimum Wage or National Living Wage once the sacrifice is taken into account.

This means:

• Payroll must check that your post-sacrifice pay still meets minimum wage rules
• If it doesn’t, you won’t be able to use salary sacrifice for that benefit
• This can limit eligibility for lower earners or higher-cost benefits

This is a legal requirement that employers have to follow.

Salary deduction doesn’t have this restriction. Because deductions happen after tax, your gross pay stays the same, so minimum wage rules aren’t affected.

This is why you’ll sometimes see salary sacrifice schemes described as “subject to eligibility checks”. 

The good news is that this check is usually handled entirely by payroll or the scheme provider. If you’re eligible, you won’t need to worry about it. And if you’re not, it’ll be flagged before anything is set up, meaning you’ll never ‘accidentally’ fall under the legal minimum wage threshold.

Some salary sacrifice providers go to great lengths to make the scheme as accessible and affordable to as many people as possible. For example, at loveelectric we offer used EVs as part of our EV salary sacrifice scheme so that the benefit can be used by more employees.

Which is better: salary sacrifice or salary deduction?

Salary sacrifice isn’t something you can apply to just any perk. It only works when the benefit is offered through a properly set-up, HMRC-compliant scheme. When that’s in place, it can deliver far more value than a simple payroll deduction. 

It’s typically the better option when:

• The benefit is supported by tax incentives (like pensions or electric cars)
• You want the benefit to feel meaningful
• You’re thinking about retention, attraction and long-term value

Because salary sacrifice reduces employees’ taxable pay, it often delivers much higher perceived value without increasing your direct costs. In many cases, employers also make National Insurance savings, which can help keep the scheme cost-neutral.

Salary deduction is often the right choice if:

• The benefit you want to offer doesn’t come with any tax advantages
• You want minimal setup and no contractual changes
• The benefit is low-cost or optional

For things like gym memberships, professional subscriptions, or small voluntary benefits, salary deduction is usually sufficient. It’s easy to administer and doesn’t change how pay or benefits are calculated.

Choosing your salary sacrifice scheme

Once you’ve decided that salary sacrifice is the right structure, the next question is which scheme to offer.

Your options are: 

• Pensions
• Cycle to Work
• Childcare (legacy schemes only)
• Electric cars

All of these technically qualify, but they don’t all deliver the same level of impact.

Pensions are already expected. Cycle to Work appeals to a small group. Childcare is no longer open to new joiners. So if the goal is to introduce a salary sacrifice benefit that employees actually notice, talk about, and use, attention quickly turns to electric cars.

An EV scheme takes one of the biggest everyday costs employees face and applies the full advantage of salary sacrifice to it. Plus, it helps companies meet sustainability goals. 

And with a salary sacrifice scheme provider like loveelectric, your employees get access to the lowest EV prices in the UK. Maximum affordability means maximum uptake at your company.

Everyone at your company will be excited to take advantage, saving up to 60% off on their dream EV. Including you! Check out the range of cars available and find out how much you can save with our salary sacrifice calculator. 

Salary sacrifice and salary deduction FAQs 

What’s the main difference between salary sacrifice and salary deduction?

The key difference is when tax is applied.

• Salary sacrifice reduces an employee’s salary before Income Tax and National Insurance are calculated.
• Salary deduction takes money after tax and National Insurance have already been applied.

Can any benefit be offered through salary sacrifice?

No. Salary sacrifice can only be used for benefits that are delivered through a formal, HMRC-compliant scheme.

Common examples include pensions, Cycle to Work, and electric car schemes. You can’t simply apply salary sacrifice to any perk or expense, it has to be structured properly to meet tax and employment rules.

Salary deduction is more flexible, but it doesn’t offer the same financial advantages.

Is salary sacrifice more expensive for employers to run?

Not necessarily. In many cases, salary sacrifice schemes are cost-neutral for employers.

Because employees’ taxable pay is reduced, employers often save on National Insurance contributions, which can help offset scheme costs. With well-designed schemes, employers can offer a high-value benefit without increasing salary budgets.

Should we offer salary sacrifice or salary deduction if we’re just starting out?

If you want to offer a benefit that employees genuinely value, and one that supports retention, attraction, and long-term engagement, salary sacrifice is usually the better starting point when a suitable scheme exists.

Salary deduction works well for smaller, optional perks. Salary sacrifice is the better tool when you want to make a meaningful impact without increasing pay.

Can we offer both salary sacrifice and salary deduction benefits?

Yes. Many employers use both, depending on the benefit.

Salary sacrifice is typically reserved for scheme-based, tax-efficient benefits (like pensions or EVs), while salary deduction is used for simpler, optional extras. They’re not competing approaches because they solve different problems.
