Tesla Mileage Logbook & BIK Rules in Ireland: What Revenue Expects for Electric Company Cars

Yes. The business-versus-private mileage obligation applies fully to a 100% electric Tesla in Ireland. Revenue ties your tax directly to proven business kilometres, and a battery-electric car (0g/km CO2, Category A1) still needs a contemporaneous logbook to set your Benefit-in-Kind, apportion motor expenses and support VAT recovery. Being electric lowers the rates you pay, and you must still record and prove every business journey.

Who is concerned?

The rules apply to company-car drivers (and directors) charged Benefit-in-Kind as notional pay, whose BIK band is set by their annual business kilometres; self-employed sole traders and partnerships claiming motor expenses and capital allowances, who can only deduct the business proportion; and any VAT-registered business seeking partial VAT recovery on a qualifying passenger vehicle or on electricity used for business charging. Employers calculate and report the BIK; the employee must supply the mileage records.

For your electric Tesla

For a company car, an electric Tesla emits 0g/km of CO2, placing it in the most favourable band (Category A1 for 2026). The taxable benefit still swings with your proven business mileage: it falls from 15% of Original Market Value (0–26,000 business km) to 12% (26,001–39,000), 9% (39,001–48,000) and just 6% above 48,000 business km. Before that percentage is applied, an EV's OMV is first reduced by €10,000 (the reduction for categories A1 to D) plus a €20,000 EV-specific relief for 2026 (€30,000 in total). That total falls to €15,000 in 2027 (€5,000 plus €10,000) and €2,500 in 2028, as Budget 2027 (6 October 2026) did not extend the EV relief. Drivers with low business kilometres can also claim a 20% reduction of the cash equivalent, but only if they travel between 8,000 and 24,000 business km, work at least 20 hours per week, spend at least 70% of working time away from base, and keep a logbook.

What to record

  • ✓Date of each journey.
  • ✓Start and end location (from / to).
  • ✓Distance travelled, in kilometres.
  • ✓The business reason or purpose of the trip.

How to stay compliant

  1. 1

    Log every journey as you drive

    Capture the date, from/to, distance in kilometres and business purpose of each trip contemporaneously: Revenue expects a live logbook as evidence. A year-end reconstruction is weak and easily challenged.

  2. 2

    Keep a running business-kilometres total

    Your annual business-km figure sets your BIK band, your self-employed expense apportionment and your VAT business-use test. Track the business-versus-private split continuously so you can prove which band you fall into.

  3. 3

    Export and retain for six years

    Produce a clean, timestamped logbook for your employer, accountant or a Revenue audit, and keep all supporting records for six years so you can meet Revenue's look-back.

Weak or missing records default you to the worst outcome. Revenue may treat 8,000 km as private, the 20% low-business-kilometres BIK reduction becomes unavailable, and more BIK tax is charged. For the self-employed, the private element of motor expenses and capital allowances is disallowed and added back. Reclaimed VAT is clawed back if 60% business use is not met or evidenced. On an audit, under-declared BIK or over-claimed expenses and VAT lead to additional tax plus interest and penalties, and records must be produced across a six-year look-back.

Frequently asked questions

Does my electric Tesla still need a mileage logbook in Ireland?+

Yes. Being a 0g/km EV lowers your BIK rate (Category A1, from 15% down to 6% of OMV), and the obligation remains: you still need a contemporaneous logbook to prove business kilometres for BIK, motor expenses and VAT recovery.

Can I reclaim VAT on the electricity used to charge my Tesla for business?+

VAT on electricity used to charge an EV for business is recoverable, apportioned by your business-versus-private mileage split. The same logbook that supports your BIK also substantiates this recovery. An employer generally cannot recover VAT where an employee charges a company car at home.

What happens if I cannot prove my business mileage to Revenue?+

Revenue lets your employer assume 8,000 km are private, and the 20% low-business-kilometres BIK reduction cannot be claimed without a logbook. For VAT, up to 20% recovery on a qualifying passenger vehicle requires at least 60% business use, tested over a two-year period. If that business use is not proven, the recovered VAT is clawed back.
