This guide explains how to use the Count.ie company-car bik and take-home impact. Calculate 2026 car BIK, supported EV reductions, a single employee's take-home impact and employer-cost assumptions. Follow the inputs, method and worked example below, then compare your own scenario.
Guide written .
Open the Company-car BIK and take-home impact calculatorWhat to prepare
- Use the contract, pay records, service dates and applicable working pattern.
- Identify the relevant jurisdiction, rule date and employee category.
- Separate contractual arrangements from statutory minima and employer-cost estimates.
Understand the inputs
- Assumed employer PRSI rate for incremental BIK (%)
- Scenario input only; confirm payroll classification/rate. This input is applied throughout the estimate, not phased through the year.
The calculation method
2026 BIK = max(0, adjusted OMV × CO₂/mileage band − direct employee contribution). OMV reduction is €10,000 except category E, plus €20,000 for electricity-only cars. Compare the existing published-2026 single PAYE calculation with and without notional pay; remove notional cash and direct contributions from take-home.
Worked example
Illustrative inputs and their result.
Example inputs
- Original Irish market value including VAT/VRT (€)
- 55000
- Electricity-only car (not a hybrid)
- Yes
- Certified CO₂ emissions (g/km)
- 0
- Full-year business distance excluding commuting (km)
- 23000
- Direct annual contribution to employer (€)
- 0
- Annual cash salary excluding BIK (€)
- 60000
- Annual personal pension contribution (€)
- 0
- Assumed employer PRSI rate for incremental BIK (%)
- 11.4
- Employer's annual lease/ownership and running costs (€)
- 8000
Calculated example result
- Taxable Benefit
- €3,750.00
- Monthly Take Home Reduction
- €147.62
How to interpret the result
A payroll or employment estimate does not determine a legal entitlement by itself. Contract terms, eligibility, service history and specific statutory exceptions can matter.
Compare the same role and working pattern when changing a pay or staffing assumption. Confirm statutory questions with the cited guidance or a qualified adviser.
Common mistakes to avoid
- Do not mix weekly, monthly and annual pay without converting consistently.
- Check whether service dates and working days are included as the method requires.
- Do not assume all employees share the same eligibility or contribution treatment.
Assumptions and sources
Full-year single-assessed Class A employee aged 35, standard tax credits. Employer PRSI is an entered scenario rate. Vans, part-year availability, pool cars, special 20%-reduction concessions, married/medical-card/age profiles and foreign OMV adjustments are not supported.
Rules checked . Baseline rules year: 2026. Reviewed scope: 2026 full-year car/EV cash equivalent; restricted employee PAYE scenario. This does not verify every selectable year, date or Budget announcement profile.
