What is a French tax return package (liasse fiscale)? 2026 guide

The liasse fiscale is the tax filing package a French company under a real-results regime sends each year to the tax authority: a main return (2065-SD for corporate tax, 2031-SD for BIC, 2035-SD for BNC) plus supporting schedules, 19 schedules 2050-SD to 2059-G-SD under the standard regime, 7 schedules 2033-A-SD to 2033-G-SD under the simplified one. Electronic filing is mandatory.

Every year, companies operating in France under a standard tax regime must submit a formal tax filing package to the French tax authority (Direction Générale des Finances Publiques). This package is called the liasse fiscale. For non-French directors, holding company boards, or international groups with a French subsidiary, the concept can be opaque. This guide explains what the liasse fiscale contains, which forms apply depending on the tax regime, how French taxable profit differs from accounting profit, and what penalties apply if the filing is late or incomplete.

All figures, thresholds and deadlines below relate to financial years ending 31 December 2025, with filing due in 2026.

The liasse fiscale is the full set of standardised forms (a main tax result declaration plus supporting schedules) that a company subject to a real (réel) tax regime submits annually to the French tax authority to determine its taxable income. For financial years ending 31 December 2025, the electronic filing deadline is 20 May 2026. Without a filed liasse fiscale, the tax authority cannot assess the corporate tax due.

The liasse fiscale is not a single form. It is a structured filing dossier consisting of:

• A main declaration (the déclaration de résultat), which states the taxable profit or loss for the year after fiscal adjustments;
• A set of supporting schedules (tableaux annexes) that break down the balance sheet, income statement, fixed assets, provisions, tax credits, group relationships, and prior-year losses carried forward.

The filing must be submitted electronically, either through the EDI-TDFC system (via an approved accounting partner, accountant, or certified software) or through the company's online professional account on impots.gouv.fr (mode EFI). Paper filing is permitted only in exceptional, derogatory circumstances.

The liasse fiscale is distinct from the statutory accounts filed with the commercial court (greffe), from VAT returns, and from the payment of corporate tax. Each of these follows a separate calendar and separate forms.

Foreign directors often conflate these documents. The table below clarifies the distinctions under French law.

The statutory accounts go to the greffe and are publicly accessible. The liasse fiscale goes to the tax authority and is confidential between the company and the administration.

Tax package to the DGFiP, statutory accounts to the court registry#

Both filings start from the same bookkeeping, but they share neither their content, nor the event that starts the clock, nor their publicity regime. Treating them as one is the quickest way to miss one of the two.

Accounts are approved within six months of the year-end for an SA, an SARL or an EURL; for an SAS or an SASU, the shareholders set the deadline themselves. In practice, schedules 2050-SD to 2059-G-SD are never filed with the registry: they stay between the company and the tax authority, whereas the statutory accounts become readable by any third party unless the confidentiality option is used.

The form set depends on the company's tax regime and income category. Note that form numbers are French administrative codes and are not translated.

The thresholds sit in Article 302 septies A bis of the French Tax Code (Code général des impôts, CGI), which since recodification refers to Article L. 162-4 of the code des impositions sur les biens et services. They are tested against the previous calendar year's revenue, excluding VAT:

• €945,000 HT for sales of tangible goods, restaurant services, or the provision of accommodation;
• €286,000 HT for all other service activities.

Crossing a threshold in year N moves the company to the standard regime from year N+1: schedules are never switched mid-year. From that point the more detailed 2050 to 2059-G schedules replace the simplified 2033 series. A company may also opt for the standard regime while staying below the thresholds.

The supporting schedules, series by series#

The official 2032-NOT-SD guidance for the 2026 vintage is explicit: the standard-regime package consists of schedules 2050-SD to 2059-G-SD, that is 19 schedules. Each one carries the wording "mandatory form" under Article 53 A CGI.

Under the simplified regime the series drops to seven condensed schedules.

For liberal professions filing a controlled declaration, form 2035-SD comes with 2035-A-SD (tax income statement: receipts and expenses), 2035-B-SD (tax income statement: determination of the result), 2035-E-SD (value added produced during the year), 2035-F-SD (share capital) and 2035-G-SD (subsidiaries and shareholdings). The legal basis for these annexes is Article 40 A of Annex III to the CGI. Partnerships and similar groupings add form 2035-AS-SD, which shows how the result is allocated between the partners.

Any company or individual trader subject to a réel (actual results) tax regime must file. This covers:

• Companies subject to corporate tax (IS): SA, SAS, SASU, SARL, EURL that has opted for IS, SCI subject to IS;
• Sole traders and partnerships subject to income tax in the BIC category under a réel regime;
• Liberal professions filing under the controlled declaration (BNC déclaration contrôlée);
• Farming businesses under a réel agricultural regime, which file the dedicated 2143 and 2139 form series rather than the 2050 or 2033 schedules.

Auto-entrepreneurs (micro-entrepreneurs) do not file a liasse fiscale. The micro-BIC and micro-BNC regimes apply a flat-rate profit allowance to turnover. The individual files form 2042-C-PRO alongside their personal income tax return. No supporting schedules, no balance sheet annexes.

For international structures, an EURL whose sole shareholder is an individual and which has not opted for IS remains subject to personal income tax (BIC category) and must file a 2031-SD rather than a 2065-SD.

This is the least understood aspect of the liasse fiscale for non-French directors. French tax law and French accounting standards diverge on several points. The liasse fiscale reconciles them.

The formula: taxable profit = accounting profit + fiscal add-backs (réintégrations) - fiscal deductions (déductions extra-comptables).

Common add-backs increase the taxable base above accounting profit:

• Administrative fines and penalties (e.g. late payment fines imposed by public authorities);
• Depreciation on passenger vehicles above the statutory ceilings, and other luxury expenses listed in Article 39-4 CGI (line WF of schedule 2058-A);
• Business-entertainment expenses that exceed allowable limits;
• Provisions disallowed under French tax rules;
• Interest on shareholder current accounts above the legally deductible rate.

Common deductions reduce taxable profit below accounting profit:

• Parent-subsidiary participation exemption (régime mère-fille, Articles 145 and 216 CGI): the net income from qualifying shareholdings is deducted from taxable profit, whatever the country in which the subsidiary is established, subject to the statutory exclusions (notably shares in companies established in a non-cooperative State or territory). A quote-part de frais et charges equal to 5% of the gross dividend remains taxable, so the deduction is 95% of the gross amount, not 5%. The rate falls to 1% for distributions between members of a French tax group and, under conditions, for dividends from an EU or EEA subsidiary that could belong to that group;
• Long-term capital gains taxed at a reduced rate, reported separately;
• Certain qualifying tax-exempt income.

Worked example (representative illustration):

Corporate tax is assessed on €104,100, not on €100,000. The standard rate is 25%, and SMEs that meet the conditions of Article 219, I-b CGI pay a reduced 15% rate on the profit band up to €42,500, so 25% does not apply to the whole result. Here the €4,100 difference falls inside the 25% band and means an additional €1,025 in tax. Each of these adjustments must be supported by documentation in the working file. For groups with French subsidiaries benefiting from the parent-subsidiary regime, these adjustments can be considerably larger.

Schedule 2058-A, where the reconciliation actually happens#

Under the standard regime, the whole reconciliation lands on a single form: schedule 2058-A-SD, "détermination du résultat fiscal". It reads in two blocks, block I for add-backs and block II for deductions, ending with the taxable profit (line XN) or the loss carried forward (line XO).

That figure does not stand alone. Schedule 2058-B-SD tracks the stock of losses carried forward, the paid-holiday accruals and the non-deductible provisions, while 2058-C-SD carries the allocation of the result and various disclosures. Under the simplified regime the same work is condensed onto schedule 2033-B-SD, with line 350 for miscellaneous deductions and line 372 for the loss of the year.

For financial years ending 31 December 2025:

• 5 May 2026: legal deadline for paper filing (second working day after 1 May);
• 20 May 2026: deadline for electronic transmission via EDI-TDFC or EFI, which carries an additional 15 calendar days.

For companies with a financial year ending on a date other than 31 December, the filing must be submitted within three months of the year-end date.

Electronic filing is mandatory for all standard-regime companies under Article 1649 quater B quater CGI.

For full details on the 2026 calendar, interim payment deadlines, and how to request a deadline extension in exceptional circumstances, see the dedicated article: Date limite de dépôt de la liasse fiscale 2026.

Missing the deadline or filing on paper when electronic submission is mandatory carries specific financial penalties under French tax law.

Penalties for late or missing declaration (Article 1728 CGI):

Late interest (intérêts de retard) under Article 1727 CGI accrue at 0.20% per month on the tax not paid on time, after deducting the instalments that were duly paid.

Penalty for non-electronic filing (Article 1738 CGI):

Where paper filing is used when electronic submission is required, a penalty of 0.2% of the tax due applies, with a minimum of €60 per declaration.

For a company with €200,000 of taxable profit and IS of €50,000, a 40% surcharge (where a formal notice was issued and ignored) amounts to €20,000, plus late interest. Timely filing is the most straightforward risk management measure available.

In practice, four issues account for the majority of errors seen when reviewing client files or taking over from a previous accountant.

1. Unreconciled accounts at filing date. Year-end accruals, deferred charges, and provisions calculated outside the accounting system create discrepancies between the trial balance and the liasse figures. These surface at audit or during a tax review.

2. Wrong regime applied. The regime for year N depends on the previous calendar year's revenue. A company that crossed a threshold in N-1 must serve the 2050 to 2059-G schedules in N; continuing with the 2033 series produces an incorrect declaration that has to be filed again.

3. Missing fiscal add-backs. Fines, excess shareholder loan interest, and disallowed provisions that are booked in the accounts but not reported as réintégrations in the liasse understate taxable profit. The tax authority can reassess within the standard three-year limitation period, plus late interest.

4. Confusing the filing deadline with the payment deadline. Filing the liasse fiscale by 20 May does not discharge the payment obligation. For a 31 December year-end, the corporate tax balance is paid with form 2572-SD by 15 May of the following year (Article 1668, 2 CGI). 15 September is one of the four instalment dates, alongside 15 March, 15 June and 15 December. For companies with complex cross-border tax positions, the French corporate tax practice can help model both the filing and payment calendars in advance.

A well-prepared liasse fiscale is the output of a structured year-end process, not a last-minute exercise. The four steps we apply consistently in our closing engagements are:

1. Clean the accounting records before any fiscal work begins. Reconcile all third-party accounts, post accruals and provisions on documented calculations, and close the trial balance. No fiscal adjustment is reliable on an unreconciled accounting base.
2. Document every fiscal adjustment with a source reference. Each add-back and deduction entry in the liasse should trace back to a memo, a legal document, or a calculation worksheet retained in the permanent file.
3. Cross-review the liasse before transmission. The package is reviewed a second time after a deliberate pause, against a written control grid: consistency between the main declaration and its supporting schedules, prior-year carry-forwards, and agreement between the balance sheet totals and the final trial balance.
4. Transmit early. EDI platforms can experience congestion in the final days before the 20 May deadline. Filing five to ten days early provides a safety margin to resolve any transmission error.

If your French subsidiary or French-registered company does not yet have a structured year-end process, the Paris accounting practice can implement one with you before the next closing cycle.
