Understanding Tax on Company Benefits: A Simple Guide for Employees and Employers

Ever received a company car, gym membership, or private medical insurance as part of your job? These perks—also known as “benefits in kind”—can make your job more rewarding, but they can also affect how much tax you or your employer will pay.

If you’re scratching your head about how all these things work, you’re not alone. Taxes on employee benefits can be a bit tricky. But don’t worry! In this blog post, we’ll break it down in simple terms so you know exactly what to expect—whether you’re giving or receiving these extras.

What Are Company Benefits?

Let’s start with the basics. Company benefits, or “benefits in kind,” are perks that an employee receives in addition to their salary. These can be small perks like free lunches or bigger ones like a company car or private healthcare.

So, what’s the big deal? Well, many of these benefits are considered taxable by HMRC—the UK’s tax authority.

Common Company Benefits You Might Receive

Some popular examples of benefits include:

• Company cars for personal use
• Health insurance paid for by your employer
• Subsidized gym memberships
• Interest-free loans over £10,000
• Accommodation provided by your employer
• Shares or share options

These extras can make a job very attractive, but they may also bump up your tax bill. Let’s take a closer look at how that works.

How Are Company Benefits Taxed?

Here’s where things get interesting. Not all benefits are treated the same by HMRC. Some are tax-free, but others are taxable and must be reported. If they are taxable, they’ll either be:

• Added to your taxable income – This means you’ll pay more tax through PAYE (Pay As You Earn).
• Reported by your employer via a P11D form – More on that shortly.

Think of it this way: if your employer gives you something of value instead of adding more money to your payslip, HMRC still wants to make sure it gets its share.

Real-Life Example

Imagine this: your employer gives you a company car you can also use on weekends. That’s a big plus, isn’t it? But because you get personal use out of it, HMRC sees it as extra income. The value of the benefit gets calculated and added to your yearly earnings. You pay income tax based on that total figure.

What Is a P11D Form?

Okay, here’s a term that often pops up: P11D. This is a form your employer uses to tell HMRC about the benefits you’ve received during the year.

Employers must submit this by the 6th of July *after* the end of the tax year (which ends on 5 April). You’ll also receive a copy for your records.

If you get your benefits “payrolled”—meaning the value is added to your pay each month—then you won’t see a P11D. Your tax gets adjusted in real time instead. Pretty handy, right?

Employer Responsibilities and Tax Implications

It’s not just employees who need to pay attention. If you’re an employer, offering perks can make your team happier and more motivated—but it also comes with responsibilities.

Here’s what employers need to do:

• Identify taxable benefits and assess their values
• Complete P11D forms for each employee (or use payroll if opted)
• Pay Class 1A National Insurance on most benefits
• Submit P11D(b) – This tells HMRC the total NIC (National Insurance Contributions) due on the benefits

For the 2023/24 tax year, the Class 1A NIC rate is 13.8%. So, giving benefits can cost employers money, too.

Which Benefits Are Tax-Free?

You might be wondering—are there any free perks from tax?

Yes! Not every benefit is taxable. Here are some common items that usually escape the taxman:

• Workplace parking
• Bikes and cycling equipment under the Cycle to Work scheme
• Mobile phones (if provided mostly for work)
• Staff canteens (if free or subsidized and available to all staff)
• Routine eye tests and glasses, if required for screen use

Nice to know, right? These can add real value to your job without added tax.

How to Check If You Owe Tax on a Benefit

Got a benefit and unsure if it’s taxable? A good first step is to speak with your HR or payroll department—they’ll usually know what counts.

You can also:

• Check your annual P11D form
• Review your tax code notice and see if benefits are included
• Use HMRC’s online tax checker tool

If your P11D lists any benefits, and your tax code doesn’t already factor them in, you may need to pay the difference through a Self Assessment or through an adjusted tax code.

Self-Employed? The Rules Are Different

This guide is mostly for employees, but if you’re self-employed, company benefits work differently. You don’t usually receive “benefits” in the same way. Instead, you claim allowable expenses and capital allowances for business-related items.

If you’re unsure about what counts, an accountant can help make sense of it.

Tips to Keep Your Tax Low (Legally!)

Nobody likes paying more tax than they must. Luckily, there are a few ways both employees and employers can work smarter:

For Employees:

• Use salary sacrifice wisely – Swap part of your salary for tax-efficient benefits such as pensions or cycle-to-work schemes.
• Review your tax code – Ensure benefits are properly included to avoid surprise bills.
• Claim any allowable expenses – Especially if you work from home or travel for work.

For Employers:

• Offer more tax-free benefits like Cycle to Work or staff meals instead of taxable perks
• Consider payrolling benefits to simplify reporting and spread out employees’ tax burden
• Stay on top of deadlines to avoid penalties from HMRC

Common Mistakes (And How to Avoid Them)

Filing your P11D late? Forgetting Class 1A NICs? These are common pitfalls. Here’s how to steer clear:

• Mark your calendar – Forms are due 6 July, payments by 22 July
• Keep records all year round – Don’t wait until the last minute
• Use payroll software or consult accountants – They can keep you compliant

Final Thoughts: Know Your Benefits, Know Your Taxes

Understanding tax on company benefits doesn’t have to be overwhelming. Think of it like this: HMRC wants tax on anything that gives you extra value beyond your pay.

If you’re an employee, familiarize yourself with which benefits are taxable and how they affect your income. If you’re an employer, make sure you’re reporting and paying what’s due.

Paying attention can save everyone time, money, and stress—making those company perks even more rewarding.
