    FAQ: Tax Preparation Services

    Who needs to file a tax return in France?

    Every person residing in France for tax purposes, including in Lille, is legally bound to file an income tax return to the fiscal authorities. This applies to employees, self-employed professionals, entrepreneurs, and pensioners. Even if a taxpayer does not earn taxable income, they may still need to file a return to benefit from fiscal advantages or to prevent fines in case of future regularization.

    Non-French citizens living in France must also report their earnings if they are fiscally domiciled in France or work within the country. In the same way, those who own property in France, regardless of their residence status, are subject to declaration obligations for any income generated from rentals.

    What are the deadlines and penalties for late filing?

    Each year, the tax authorities in France publishes specific submission timelines for income tax returns, generally ranging from mid-May and early June, depending on the taxpayer’s department and submission channel (by post or electronically).

    As registered tax advisors, we use specialized tax software that enables us to prepare your tax return as early as January 1st. To ensure accuracy, optimize your tax situation, and avoid last-minute stress, we recommend contacting us as early as possible.

    Not complying with the official deadlines may trigger late fees, making early preparation even more important.

    A missed deadline leads to an additional fine: a 10% penalty applies if no notification is issued, which can rise to 40% if the fiscal administration officially issues a notice. Penalties for late payment of 0.20% per month is also added to the amount due. If the error is found to be deliberate or dishonest, higher penalties may be applied.

    How can I legally reduce my income tax?

    There are several legitimate methods to lower your tax bill in France. Real estate investment is an reliable way to enhance your tax situation, particularly through the furnished rental scheme for non-professionals, which provides fiscal incentives.

    Other fiscal tools include the Malraux scheme, which grants major tax relief for the rehabilitation of historic properties; the déficit foncier mechanism, which helps reduce taxable income through renovation deductions; and the Historic Monuments program, offering notable benefits for the conservation of protected properties.

    French assurance-vie is another advantageous option: after 8 years, it is subject to favorable tax treatment, making it an excellent tool for wealth transfer and fiscal planning.

    Participation in small business equity or fiscally supported funds like investment funds with tax perks can also provide a tax reduction of up to 25% of the eligible investment, depending on compliance with criteria.

    These are just a few examples! Our consultants are here to recommend the best options for tax reduction for greater efficiency.

    How to file your tax return online?

    The electronic tax submission process is the standard procedure of the French tax authorities, processed through the official government website French tax portal.

    However, as certified experts, we streamline the procedure for our clients. Instead of using their online portal, they simply fill out a dedicated form on our website.

    Once the information is entered, we handle the entire declaration process and file it electronically to the tax authorities via the EDI system, ensuring correctness, compliance, and speed—without any need for clients to access impots.gouv.fr.

    After submission, the tax administration determines what is payable or refundable or any eligible reimbursement.
