🚗 Company car tax: the basics (and why it gets complicated fast 👀)
Company cars might look like a simple employee benefit… but the tax rules behind them are anything but.
Here’s a clear breakdown of how it works 👇
💼 When is a company car taxed?
If an employee (or their household) gets a company car that’s available for private use, a tax charge usually applies.
👉 It doesn’t matter if they actually use it privately
👉 Just that it’s available for private use
💰 Cash equivalent: how tax is calculated
The taxable benefit is based on:
• The car’s original list price (not what was paid)
• Plus optional extras and VAT
• Multiplied by a CO₂-based percentage banding system
💡 Important points:
• Employee capital contributions can reduce the value (up to £5,000)
• Employee payments for private use also reduce the charge
• Diesel cars may have an extra 4% charge (unless RDE2 compliant)
• Maximum charge is capped at 37% of list price
⚡ Electric range matters
For lower-emission vehicles:
👉 CO₂ emissions + electric-only range determine the % charge
👉 The lower the emissions, the lower the tax bill (generally)
🚐 Cars vs vans vs pickups
Not everything is treated the same:
• Cars = most mechanically propelled vehicles
• Vans = goods vehicles under 3.5 tonnes
• Double cab pickups depend on payload (1 tonne rule is key)
👉 Classification can completely change the tax treatment.
👥 Pool cars exemption
A “pool car” can be tax-free if strict conditions are met:
✔ Used by multiple employees
✔ Not kept for one person’s exclusive use
✔ Private use is only incidental
✔ Not normally kept overnight at home
👉 If these conditions aren’t met, the exemption is lost.
⛔ Availability matters
Tax can be reduced if the car is genuinely unavailable (e.g. repairs), but:
👉 It must be unavailable for 30+ consecutive days
👉 Simply not using the car doesn’t count
💡 Bottom line
Company car tax isn’t just about the vehicle, it’s about:
➡️ Availability
➡️ Emissions
➡️ List price rules
➡️ And strict HMRC definitions
If you’re advising on company cars (or choosing one), the structure can make a big difference to the tax outcome 👍
