Every year, as tax deadlines approach, many individuals and businesses in France feel overwhelmed by the complexity of impôt sur le revenu, cotisations sociales, TVA, and the growing administrative requirements. For freelancers, consultants, and small business owners, the stress often comes from fear of errors, missing deductions, or misunderstanding social and fiscal obligations.

This is where a French tax consultant (conseiller fiscal / expert-comptable) becomes essential.
They help prevent costly mistakes, optimize your taxes, and ensure full compliance with French laws—whether you’re under the micro-entreprise, régime réel, BIC/BNC, SASU, or other structures.

This guide will help you understand when you need a tax consultant, what they can do for you, and how to find the right expert near you.

Why You Might Need a Tax Consultant in France

A French tax consultant can help with:

• Understanding TVA obligations

• Declaring revenue from rentals (LMNP/LMP)

Life events in France have a direct impact on taxes:

• Creating a business (micro-entreprise, EI, EURL, SASU…)

A tax expert helps optimize your fiscal situation and avoid unpleasant surprises.

✔ 3. Starting a Business

Launching a business in France involves choosing the right legal status, setting up accounting, and understanding social charges through URSSAF, CPAM, CIPAV, SSI, or impôts.

A consultant can assist with:
