FAQ: Tax Preparation Services
Who needs to file a tax return in France?
Anyone who is a tax resident in France, including in Dunkerque, is legally bound to file an income tax return to the tax authorities. This applies to employees, freelancers, business owners, and retirees. Even if a taxpayer does not earn taxable income, filing a declaration may still be necessary to access certain tax benefits or to avoid penalties in case of later tax adjustments.
Expats and foreign residents must also report their earnings if they live primarily in France or work within the country. Likewise, those who own property in France, regardless of their residence status, are required to file a return for any rental income received.
What are the deadlines and penalties for late filing?
Each year, the French tax office publishes specific submission timelines for annual tax declarations, generally ranging from mid-May and early June, depending on the place of residence and how the return is submitted (physical or digital).

As registered tax advisors, we rely on specialized tax software that allows us to start working on your tax return as early as January 1st. To guarantee precision, maximize your tax benefits, and stay ahead of deadlines, we suggest getting in touch as early as possible.
Not complying with the official due dates may lead to fines, making early preparation even more crucial.
A delayed filing leads to an additional fine: a 10% penalty applies if no notification is issued, going as high as 40% if the tax authorities officially issues a notice. Late payment interest of 0.20% per month is also charged on the outstanding sum. If the error is found to be deliberate or dishonest, higher penalties may be imposed.
How can I legally reduce my income tax?
There are several compliant approaches to reduce your income tax in France. Real estate investment is an reliable way to enhance your tax situation, particularly through the Non-Professional Furnished Rental (LMNP), which grants fiscal incentives.
Other tax-efficient strategies include the Malraux scheme, which offers strong incentives for the renovation of historic properties; the landlord renovation deduction, which lets property owners subtract works expenses; and the Historic Monuments program, offering important tax relief for the conservation of listed monuments.
French assurance-vie is another tax-efficient tool: after a holding period of 8 years, it is subject to favorable tax treatment, making it an excellent tool for estate planning and tax optimization.
SME investment or tax-incentivized funds like investment funds with tax perks can also lead to a tax reduction of up to 25% of the qualified contribution, depending on compliance with criteria.
There are many more possibilities! Our consultants are here to help you identify the best fiscal strategies for maximum tax reduction.
How to file your tax return online?
The electronic tax submission process is the recommended approach of the fiscal authorities in France, processed through the official government website impots.gouv.fr portal.
However, as authorized tax advisors, we make things easier for our clients. Instead of using their individual space, they simply submit a dedicated form on our website.
Once the information is entered, we manage the full tax submission and transmit it securely to the tax authorities via secure EDI connection, providing accuracy, compliance, and efficiency—without requiring clients to log in to impots.gouv.fr.
After submission, the tax administration determines what is payable or refundable or any eligible reimbursement.
