The Finance Director's Guide to Mastering Company Car Tax and BIK in 2026/27

The Impact of 15% Class 1A NICs on Fleet Cost Reduction

For the employer, the cost of a company car is largely driven by Class 1A National Insurance Contributions (NICs). With the rate effectively sitting at 15% for the 2026/27 period, the multiplier effect on BIK values has never been more relevant to your P&L.

The calculation is straightforward but punishing for high-emission fleets: P11D Value x BIK% x 15% = Annual Employer NIC Cost

When you transition a driver from a 30% BIK petrol car to a 4% BIK electric car, you aren't just saving the employee money; you are slashing the employer's NIC liability by over 85% per vehicle. This is a primary driver for fleet cost reduction strategies in 2026.

By strategically selecting vehicles with the optimum balance of P11D value and BIK banding, we help businesses mitigate the impact of the 15% NIC rate while maintaining a high-quality vehicle offering for staff.

Strategic Procurement: The £50k Expensive Car Supplement for EVs

A welcome development for the 2026/27 tax year is the adjustment to the Vehicle Excise Duty (VED) "expensive car supplement."

Previously, cars with a list price over £40,000 were subject to an additional annual supplement for five years. However, from 1 April 2026, the threshold for electric vehicles increases to £50,000.

What this means for your policy:

• Wider Choice: You can now include more premium, long-range EVs in your fleet policy without incurring the heavy VED penalty.
• Strategic Advantage: For vehicles priced between £40,000 and £50,000, the saving is approximately £440 per year compared to an equivalent ICE vehicle.
• Retention: Being able to offer "executive" level electric vehicles at a lower total cost to the business is a powerful tool for talent retention.

If your current policy is capped at £40k to avoid this tax, it is time for a strategic review. We can help you model how this threshold shift opens up new possibilities for your electric vehicle fleet.

Maximising Employee Value through Salary Sacrifice

Perhaps the most potent tool in the Finance Director’s arsenal for 2026/27 is the Salary Sacrifice arrangement. Because the BIK for EVs remains low at 4%, the tax efficiency of paying for a car out of gross salary is unparalleled.

The Problem-Solution Framework

• The Problem: Inflationary pressures and the rising cost of living make traditional salary increases expensive for the business and often underwhelming for the employee after tax and NICs.
• The Solution: A bespoke salary sacrifice car scheme. The employee "sacrifices" a portion of their gross salary in exchange for a brand-new electric car.

Because the BIK is only 4%, the employee pays very little tax on the benefit, while the business saves on Employer NICs (the difference between NICs on the sacrificed salary vs NICs on the 4% BIK). It is a rare "win-win" that supports your net zero fleet goals without increasing your overheads.
