โœˆ๏ธ Per diem: travel expenses abroad

  1. Calculate the kWh consumed for the vehicle (via your charging point or app).

  2. Multiply by the official CREG rate.

  3. Create a expense report dedicated to these charges.

๐Ÿš— Mileage allowances: professional trips with your personal vehicle

You don't have a company car, but you use your personal vehicle for professional trips (excluding home โ€“ workplace commutes)? Your company can reimburse these trips via a flat-rate mileage allowance.

๐Ÿงพ To be reimbursed: create a "mileage allowance" expense report each month or each quarter:

  • Detail your trips day by day.

  • Indicate the number of kilometres travelled, the fuel type and the COโ‚‚ emission rate of the vehicle.

๐Ÿ“† Current rate (until 30/06/2026): โ‚ฌ0.4449/km
โ€‹

๐Ÿ“Œ Cap: 24,000 km/year, to be justified.

๐Ÿšดโ€โ™‚๏ธ Cycling allowance

As a director, if you use a bicycle for your home โ†” workplace commute, you can benefit from a mileage allowance exempt from tax and social contributions.

๐Ÿงพ To be reimbursed: create a "cycling allowance" expense report each month or each quarter.

  • ๐Ÿ’ถ Amount from 01/01/2025: โ‚ฌ0.37 per km

  • ๐Ÿ“… Annual cap: up to โ‚ฌ3,610, i.e. approximately 10,028 km at this rate

  • ๐Ÿ’ผ Exempt if you opt for the flat-rate professional expenses under PIT, otherwise taxable

  • ๐Ÿข Can be combined with a company bicycle.


๐Ÿงพ Other expenses paid with your personal account

For all other types of expenses (equipment, software, restaurants, etc.):

  • ๐Ÿ“ธ Keep the receipt or invoice.

  • ๐Ÿ“ค Upload the supporting document to your expenses in the application.

  • ๐Ÿ’ณ Indicate that you paid with your personal account when submitting (the amount will be transferred to your director's current account โ€“ your accountant handles this at the end of the quarter).

๐Ÿ’ฐ Once your director's current account is in credit, you can reimburse yourself.

๐Ÿ’ก Try to avoid paying professional expenses not included in an expense report with your personal account as much as possible.
