P11D & Benefits in Kind — What Trade Company Directors Need to Know (2026)

What Is a Benefit in Kind?

A benefit in kind (BiK) is a non-cash benefit that a company provides to a director or employee that has a taxable value. Because it's a reward you receive through your company rather than as salary, HMRC wants its share — so most BiKs create both an income tax charge on the individual and a National Insurance charge on the company.

For a typical trade limited company, the benefits that crop up most often are:

• A company van or car available for private use — by far the most common BiK in the trades.
• Fuel provided for private mileage in a company vehicle.
• Private medical insurance paid for by the company.
• Beneficial (cheap or interest-free) loans, including an overdrawn director's loan account over the threshold.
• Company assets used privately — tools, equipment, a laptop or phone used beyond incidental personal use, or assets transferred to you.

Not everything is taxable. Genuine business expenses, an exempt mobile phone, reasonable trivial benefits and tools provided solely for work don't create a BiK. The line is whether there's a private benefit — which is exactly why the van-versus-car distinction below matters so much.

What Is the P11D Form?

The P11D is the form your company uses to report the benefits in kind given to each director and employee to HMRC after the end of the tax year. The UK tax year runs to 5 April, and the reporting cycle works like this:

• After the 5 April year end, the company prepares a P11D for each director or employee who received reportable benefits.
• By 6 July following the tax year, the company files the P11D(s) with HMRC and gives each individual a copy of their own P11D.
• The company also files a P11D(b), which is the declaration and the calculation of Class 1A National Insurance due on the benefits.
• The Class 1A NIC must be paid to HMRC by 22 July if paying electronically (19 July for a cheque, but electronic is the norm).

Miss the 6 July filing deadline and HMRC charges penalties of around £100 per month per 50 employees, so even a one-director company should diarise the date. The employee doesn't pay the tax through the P11D itself — HMRC collects it by adjusting the individual's tax code or through their Self Assessment return (more on that below).

Big Change Coming: Payrolling Benefits in Kind

HMRC has announced that payrolling benefits in kind is becoming mandatory. Instead of reporting benefits once a year on a P11D, the taxable value of most benefits will be put through the payroll in real time, so the tax is collected month by month alongside salary — and the annual P11D for those benefits disappears.

The original target was April 2026, but the start date has been pushed back. Because the timeline has shifted and could move again, do not assume a particular year — check the current mandatory start date with HMRC or your accountant and plan your payroll software accordingly. If you already voluntarily payroll benefits, you're ahead of the curve. Note that Class 1A NIC on the benefits is still due even under payrolling; what changes is the income tax collection method and the end of the annual P11D for payrolled benefits.

The BiKs That Matter Most for a Trade Business

Below are the benefits a trade limited company is most likely to encounter, with how each is taxed. Figures are indexed annually — treat the numbers as indicative and confirm the current year's rates.

Company Van: The Big One for Trades

For most trade businesses the company van is the central question — and the good news is that for many directors the answer is a nil benefit. There are two possible charges on a van:

• The van benefit charge — a single fixed annual figure (around £4,000+ and indexed each year) that applies if the van is available for private use.
• The van fuel benefit charge — a much smaller fixed figure that applies only if the company also pays for fuel used on private journeys.

Critically, the van benefit charge is zero if private use is only "insignificant". This is known as the restricted private use condition. In plain terms, if the van is used for business and the only private use is ordinary commuting (home to a workplace) plus genuinely incidental private use — popping to the tip on the way home, picking up lunch — then there is no taxable benefit at all. That covers the vast majority of working trade vans.

What tips a van into a taxable benefit is significant private use: using it for the weekly supermarket shop, the school run, holidays or social trips. If that's happening, the full van benefit charge applies. The distinction is the same one HMRC uses for vans vs cars — a vehicle that's genuinely a working van used like a working van is treated very differently from a car.

Because the line is about how the van is actually used, records matter. A clear company policy that the van is for business and commuting only, backed by mileage logs, protects the nil benefit if HMRC ever asks. Don't assume nil and keep nothing — assume nil and be able to prove it.

Company Car: A Far Bigger Tax Bill

A company car is taxed completely differently — and usually far more heavily — than a van. The taxable benefit is a percentage of the car's list price (P11D value), and that percentage is set by the car's CO2 emissions and, for plug-in hybrids and electric cars, its electric-only range.

• Petrol and diesel cars sit at high BiK percentages, often 25–37% of list price, so a £35,000 car can create a benefit of £9,000–£13,000 a year that you pay income tax on.
• Fully electric cars have a very low BiK percentage (a low single-digit percentage, rising slowly over the coming years). This makes a company electric car one of the most tax-efficient benefits available to a director right now.
• Car fuel benefit applies on top if the company pays for private fuel. It's calculated by applying the same CO2 percentage to a fixed fuel benefit figure, and for most directors it's not worth taking — the tax often exceeds the fuel's value. Reimbursing the company for private fuel usually beats taking the benefit.

The headline for trades: a working van can be a nil benefit, while a car almost always creates a meaningful tax charge unless it's electric. If you don't need a car for the work, a van is dramatically cheaper to run through the company. If you want a company car, make it electric.

Beneficial Loans, Medical Cover and Assets

Beneficial loans and the director's loan account

If the company lends a director money cheaply or interest-free and the balance exceeds £10,000 at any point in the tax year, a benefit in kind arises. It's calculated as interest at HMRC's official rate on the outstanding balance, less any interest you actually paid. This commonly catches directors who run an overdrawn director's loan account — keep the balance below £10,000 or charge yourself the official rate of interest to avoid the BiK. (Note the separate s455 corporation tax charge can also apply to an overdrawn loan account that isn't repaid in time — a different issue, but worth flagging to your accountant.)

Private medical insurance

If the company pays for private medical cover for you, the benefit is the premium the company pays, reported on the P11D, with income tax for you and Class 1A NIC for the company. It's a popular owner perk but it is a taxable benefit — budget for the tax.

Assets used or transferred privately

If you have private use of a company asset (beyond incidental use), the benefit is generally 20% of the asset's value each year. If the company gives or sells you an asset below market value, the benefit is broadly the market value less anything you paid. Tools and equipment used purely for the job don't count — it's personal use that triggers the charge.

Who Pays What — The Tax Split

Benefits in kind create a charge on both sides, and it's important to understand who pays which part:

• The director or employee pays income tax on the value of the benefit. HMRC usually collects this by reducing your tax code (so a bit more tax comes off any salary), or you declare and pay it through your Self Assessment tax return if you file one. There's no employee National Insurance on most benefits.
• The company pays Class 1A National Insurance on the total benefits, currently at the employer NIC rate, due by 22 July after the tax year. This is a genuine cost to the company on top of providing the benefit.

So a benefit that looks "free" because no cash changed hands still costs you income tax personally and costs the company Class 1A NIC. Factor both in when deciding whether a benefit is worth providing through the company.

Practical Tips for Trade Directors

• Keep good van usage records. A written company policy restricting the van to business and commuting, plus mileage logs, is what supports a nil van benefit if HMRC asks. The records are cheap insurance against a four-figure annual charge.
• Prefer a van over a car where the work allows — a genuine working van can be a nil benefit while a non-electric car rarely is.
• If you want a company car, go electric. The very low BiK percentage on fully electric cars makes them one of the few genuinely tax-efficient benefits available right now.
• Avoid taking private fuel as a benefit. For both vans and cars, the fuel benefit charge often costs more in tax than the fuel is worth — reimburse the company for private mileage instead.
• Watch the director's loan account. Keep it under £10,000, or charge the official rate of interest, to sidestep the beneficial loan BiK.
• Diarise the P11D dates. File and issue copies by 6 July, pay Class 1A NIC by 22 July, and check where the mandatory payrolling start date now sits.
• Talk to your accountant. The figures change every year and your specific circumstances matter — a short conversation can save a lot of tax and avoid penalties.
