Understanding Deductible Expenses and the FEC (Accounting Entries File) in France for 2026

As a freelancer or small business owner in France, understanding deductible expenses, the FEC (Fichier des Écritures Comptables), and VAT deadlines is crucial for compliance and tax efficiency. In 2026, these requirements remain central to managing your finances, whether you’re under the régime réel or micro-fiscal system. This guide explains what you need to know to stay on top of your obligations and optimise your tax deductions.

What Are Deductible Expenses for Freelancers and SMEs in France?

Deductible expenses are costs incurred in the direct interest of your business that can be subtracted from your taxable income. However, the rules differ depending on your tax regime.

Under the Régime Réel d’Imposition

If you’re under the régime réel, you can deduct a wide range of expenses, provided they are:

• Justified: You must have receipts, invoices, or contracts to prove the expense.
• Directly linked to your business activity: Personal expenses or those unrelated to your work cannot be deducted.

Common deductible expenses include:

• Purchases of raw materials or goods for resale
• Rent and utilities (if your workspace is dedicated to your business)
• Repairs and maintenance of professional equipment
• Depreciation of assets like computers, vehicles, or machinery
• Professional taxes (e.g., Cotisation Foncière des Entreprises or CFE)
• Social charges (under specific conditions)
• Home office expenses (a portion of rent, electricity, and internet if you work from home)

⚠️ Important: Mixed expenses (both personal and professional) must be split proportionally. For example, if you use your phone for business 60% of the time, you can only deduct 60% of the bill.

Under the Micro-Fiscal Regime

If you’re under the micro-fiscal regime, you cannot deduct actual expenses. Instead, the tax authorities apply a flat-rate deduction based on your turnover:

• 34% for sales of goods
• 50% for service-based businesses
• 71% for non-commercial profits (BNC)

This simplified system is designed for very small businesses with low turnover. However, if your business grows, you may need to switch to the régime réel to benefit from actual expense deductions.

What Is the FEC (Fichier des Écritures Comptables)?

The FEC is a digital file that contains all your accounting entries for a fiscal year. It is mandatory for all businesses using computerized accounting systems and must be provided to the French tax authorities (Direction Générale des Finances Publiques or DGFiP) in case of an audit.

Key Requirements for the FEC

The FEC must include 18 mandatory fields for each accounting entry, such as:

• Date of the entry
• Account number (following the French Plan Comptable Général or PCG)
• Label or description of the transaction
• Amount (debit and credit)
• Supporting document reference (e.g., invoice number)
• Journal code (e.g., sales, purchases, bank)

The file must also:

• Be chronological and sequential (no gaps in numbering)
• Be balanced (total debits = total credits)
• Exclude centralization and closing entries (e.g., year-end adjustments)

How to Ensure Your FEC Is Compliant

The DGFiP provides a free tool called TestComptaDemat to verify your FEC’s compliance before submission. Using this tool can help you avoid costly penalties.

If your FEC is missing or non-compliant, the tax authorities can impose a fine of up to €5,000. To streamline this process, tools like accounting exports can generate a compliant FEC in just a few clicks, ensuring you meet all legal requirements without the hassle.

VAT Deadlines for Freelancers and SMEs in 2026

VAT (Taxe sur la Valeur Ajoutée or TVA) is a critical part of your tax obligations. The deadlines and requirements depend on your VAT regime.

Régime Réel Normal (Monthly or Quarterly Declarations)

If you’re under the régime réel normal, you must declare and pay VAT either:

• Monthly: Between the 15th and 24th of the following month (e.g., VAT for September 2026 is due between October 15 and 24, 2026).
• Quarterly: Between the 15th and 24th of the month following the end of the quarter (e.g., VAT for Q3 2026 is due between October 15 and 24, 2026).

Régime Simplifié (Annual Declaration)

Under the régime simplifié, you file an annual VAT return (CA12) by May 5, 2026, for the fiscal year ending December 31, 2025. You may also need to pay semi-annual installments in July and December.

Franchise en Base (VAT Exemption)

If your turnover is below the VAT threshold, you are exempt from VAT declarations. For 2026, the thresholds are:

• €94,300 for service-based businesses
• €100,300 for sales of goods

⚠️ Note: Even if you’re exempt from VAT, you must still keep accurate records of your income and expenses for tax purposes.

How to Simplify Your Accounting and Stay Compliant

Managing deductible expenses, the FEC, and VAT deadlines can be overwhelming, especially for small business owners. Here’s how you can streamline the process:

Use Accounting Software

Accounting software can help you:

• Track deductible expenses automatically
• Generate a compliant FEC with minimal effort
• Stay on top of VAT deadlines with reminders

For example, tools offering Factur-X 2026 compliance ensure your invoices meet the latest legal standards, reducing the risk of errors during audits.

Automate Your Exports

Generating the FEC manually can be time-consuming and prone to errors. Instead, use tools that offer accounting exports to create compliant files in formats like FEC, CSV, or Excel. This saves time and ensures accuracy.

Monitor Your Cash Flow

A dashboard can provide real-time insights into your revenue, expenses, and VAT obligations. This helps you anticipate deadlines and avoid last-minute stress.
