Income Tax Paris – How to Deduct Work-Related Expenses: Standard Allowance vs. Actual Costs

If you work in Paris or elsewhere in France and have work-related expenses—such as commuting, meals, or job-specific equipment—you may be able to reduce your income tax. The French tax system allows you to choose between a standard 10% deduction and deducting your actual professional expenses (“frais réels”). By default, the 10% flat deduction applies automatically. Here’s everything you need to know about optimizing your income tax in Paris for 2025.

For official information, you can also refer to the Service-Public.fr guide on professional expenses.

The 10% Standard Deduction: Simplified Tax Relief

Who qualifies?

No specific criteria are required. The 10% allowance is automatically applied to all salaried income to reflect regular professional expenses.

What does it cover?

This flat-rate deduction is intended to cover typical day-to-day costs such as:

• Travel between your home and workplace

• Meals taken during working hours

• Purchase of personal job-related materials (e.g. documentation not reimbursed by your employer)

In 2025, the minimum deduction is €504 per person, and the maximum is capped at €14,426 per person.

Telework Tax Relief

If you received an allowance from your employer to cover work-from-home expenses, this is tax-exempt up to:

• €2.70 per remote workday

• €59.40 per month

• €626.40 per year (for 2024 income)

How to apply the standard deduction?

There’s nothing you need to do. It is applied automatically by the tax authorities. However, each member of your household can opt individually to deduct actual expenses instead if it’s financially advantageous.

Deducting Actual Professional Expenses (“Frais Réels”)

When is this option better?

If your eligible expenses exceed the amount covered by the 10% deduction, deducting actual expenses may reduce your income tax in Paris or anywhere in France. However, you must choose only one method—you cannot combine both for the same salary. Household members can each choose the most beneficial option for their situation.

What are the requirements?

To qualify for the actual cost deduction, your expenses must:

• Be necessary for your job

• Be incurred and paid during the 2024 tax year

• Be justified with receipts or similar documentation

What expenses can be deducted?

Common deductible costs include:

• Transportation between home and workplace

• Meal expenses during work

• Travel costs for professional activities

• Training costs related to your job

• Work-related tools, subscriptions, or space (if not reimbursed)

Special Notes:

• Carpooling is deductible, but only your share of the cost is eligible.

• If you use an electric vehicle, your travel-related deduction is increased by 20%.

👉 You can estimate your mileage deduction using the official kilometric expense calculator.

How to Declare Actual Expenses?

If you choose to deduct actual professional expenses instead of the standard allowance, you must:

• Report the total amount of professional expenses you’re claiming

• Include a breakdown detailing the type and amount of each expense in a note or annex

• Add to your taxable salary any reimbursements your employer gave you for professional expenses

Important:
Keep all receipts, invoices, or other proof of expenses for at least 3 years, as you may be asked to provide them in case of a tax audit.
