Absolutely! Plug-in hybrid vehicles (PHEV) can also be charged at home. CREG reimbursement applies to all electrical energy you charge at home, regardless of vehicle type (fully electric or hybrid).

CREG publishes new tariffs every quarter. These are automatically used by our calculator as soon as they become available, so you always calculate the most current reimbursement.

CREG tariffs are legally established for company cars. Show your employer the official CREG document and the PDF report from our calculator as proof of correct calculation.

Tax implications of charging cost reimbursements

Understand the fiscal aspects of CREG reimbursements for both employees and employers in Belgium.

For employees

  • Voordeel: CREG reimbursements are tax-free benefits up to the official maximum. Reimbursements within CREG limits do not count as taxable benefit in kind.
  • Aangifte: Tax return: CREG reimbursements normally do not need to be declared if they stay within official limits. However, keep all documentation.
  • Overschrijding: Exceeding limits: Reimbursements above the CREG maximum are taxed as benefit in kind and must be declared.

For employers

  • Aftrek: Business expenses: the deductibility of CREG reimbursements follows the deductibility rules of the car itself (depending on vehicle type and order date) — check with your accountant.
  • Sociale zekerheid: Social security: No social security contributions due on CREG reimbursements within official limits.
  • Administratie: Administration: Employers must keep correct records of all reimbursements and be able to demonstrate them to tax authorities.

For self-employed

Regional differences in Belgium: CREG rates per region

Flanders

Grid operator: Fluvius. Characteristics: Capacity tariffs and digital meters. CREG rates: Usually in middle range due to stable grid structure. Specifics: Green certificates can influence rates.

Wallonia

Grid operators: ORES and RESA. Characteristics: Traditional tariff structure with day/night rates. CREG rates: Often lower due to different grid costs. Specifics: Premiums for renewable energy.

Brussels-Capital Region

Grid operator: Sibelga. Characteristics: Urban grid structure with high density. CREG rates: Often highest due to urban grid costs. Specifics: Specific city regulations.

Practical implications

  • Home address determines region: Your CREG reimbursement is calculated based on where you live and charge, not where you work.
  • Moving between regions: When moving to another region, your rate must be adjusted from the moving date.
  • Border cases: If you live in one region and charge in another, the rate of the charging location applies.
