Why can electric car BIK change between 2026 and 2027?

Electric vehicle BIK calculations can include year-specific provisions that change the effective taxable base. As those provisions change over time, the estimate can change even with the same vehicle and salary inputs.

How should I compare an EV company car vs a non-EV company car?

Compare both cars in the same year first using the same salary and mileage assumptions. Then switch years to see how the estimate changes. Treat the result as planning only and validate against payroll treatment if needed.

Is the EV BIK result an exact tax figure?

No. It is an estimate for scenario planning. Payroll setup and personal circumstances can change actual outcomes.

1) Why the year switch matters

EV BIK estimates can change across years because year-specific provisions can affect the taxable base used in the calculation. This means the same car and salary can produce different estimates in different tax years.

If you are making a multi-year decision (leasing, employer fleet choice, or role change), use the year switch to understand the direction and magnitude of change.

2) A safe EV comparison checklist

Keep salary constant and compare only the vehicle scenario.
Use the same mileage assumption for both cars.
Compare one year first, then switch years for a planning view.
Validate against payroll if you already receive the benefit.

3) When the EV decision is OMV-sensitive

If two EV choices are close, small differences in OMV can move the estimated taxable benefit value. If you are unsure, test multiple OMV values to see whether your decision is robust.

A robust decision is one where the outcome stays similar across a sensible range of OMV assumptions.
