Optimising taxable profit before year-end close: 2026 guide

The year-end close is not a routine administrative step. It is the last opportunity to activate, in a documented and legally sound way, the adjustments that reduce your taxable profit under French tax law. Once the closing date passes, your room for manoeuvre narrows sharply.

This guide covers the core mechanisms under French law, the thresholds applicable in 2026, and a full worked example showing the concrete impact of a well-structured pre-close tax review.

In brief: before the close, you can legally reduce your résultat fiscal (taxable profit) by recording justified provisions, accrued charges (charges à payer) attachable to the financial year, and by verifying mandatory add-backs such as vehicle depreciation in excess of the statutory cap. These adjustments flow through form 2058-A of the liasse fiscale. A structured review conducted four to eight weeks before the closing date is the realistic minimum to act effectively.

In French accounting, the résultat fiscal is not simply the profit shown in your income statement. It is derived from your accounting profit through a series of extra-accounting adjustments: certain recorded expenses are not tax-deductible (add-backs, or réintégrations), while other tax-deductible items may not yet be recorded (deductions). Form 2058-A of the liasse fiscale formalises this reconciliation.

Acting before the close gives you two distinct advantages. First, you can record the deductible charges and provisions that already exist for the financial year but have not yet been entered. Second, you can identify unavoidable add-backs early enough to manage their cash impact on the corporate income tax (impôt sur les sociétés, or IS) due.

Waiting until the tax return to discover these items means reacting. Anticipating them means steering.

A note for 2026: an exceptional surcharge on IS (CESBE) applies to groups with turnover exceeding €1.5 billion. This affects roughly a hundred large French groups and has no bearing on the vast majority of SMEs.

Your accounting profit and your taxable profit diverge systematically. The table below summarises the most common adjustments.

Table — Common add-backs and deductions (form 2058-A)

This framework applies under the French Code général des impôts (CGI). It is specific to French tax law and does not correspond directly to UK or US tax treatments.

1. Accrued charges (charges à payer) and deferred income#

Under French tax law, an expense is deductible in the year the service was performed, even if the invoice has not yet been received. This is the matching principle as applied in French fiscal doctrine (BOI-BIC-CHG-40). A consultant's invoice covering December, received in January, must be accrued at the December close.

In practice: review all commitments not yet invoiced at year-end — professional fees, rent, subcontracting, maintenance. Each documented accrual directly reduces the taxable base.

2. Provisions for risks and charges (Art. 39-1-5° CGI)#

A provision is tax-deductible in France only when three cumulative conditions are met:

• Probable: the loss or charge must be probable, not merely possible.
• Clearly identified: the amount must be estimated with sufficient precision, even if approximate, and supported by documentation.
• Attachable to the year: the underlying facts must have arisen during the financial year being closed.

These conditions are set out in BOFiP reference BOI-BIC-PROV-10. A provision created "by way of caution" without documented justification will be systematically reversed upon tax audit.

Common valid provisions: employment tribunal proceedings with formal notice received, contractual warranty obligations on completed sales, stock write-downs based on a valued physical inventory.

3. Depreciation: accelerated allowances and the vehicle cap#

Accelerated (dérogatoire) depreciation allows certain qualifying assets to be depreciated for tax purposes faster than their economic useful life. The gap between tax depreciation and accounting depreciation flows through a regulated reserve, with a deferred IS impact.

For passenger vehicles, Article 39-4 CGI caps the deductible depreciation base according to CO2 emissions. The 2026 scale is as follows:

Table — Passenger vehicle depreciation caps 2026 (Art. 39-4 CGI)

This cap applies to the acquisition price including VAT, and extends to long-term lease (LLD) and hire-purchase (LOA) contracts. The portion of depreciation above the cap is added back each year over the vehicle's depreciation period.

4. Doubtful receivables and stock write-downs#

A receivable from a client facing financial difficulty can be provisioned, provided objective evidence exists at the closing date: a formal demand letter that went unanswered, insolvency proceedings opened, documented correspondence. A stock write-down requires a valued physical inventory confirming that net realisable value falls below cost.

5. Remuneration versus distribution trade-off#

If the year is expected to be profitable, a supplementary management remuneration decided and recorded before the close reduces the IS base. The charge is deductible provided it corresponds to actual work performed and is not excessive relative to market norms (Art. 39-1-1° CGI).

Dividends, by contrast, are not deductible from the company's profit. The trade-off between additional remuneration and profit retention must weigh social charges, the director's personal tax position, and the company's equity requirements. See our analysis of French holding company taxation for structures involving dividend repatriation.

Consider a SARL whose financial year ends 31 December 2025. A review conducted in mid-November produces the following findings.

Starting position

Accounting profit before tax: €120,000

Add-backs identified

• Passenger vehicle acquired for €40,000 TTC, emitting 130 g/km CO2 (cap: €18,300). Depreciation was calculated on the full €40,000 over five years. Non-deductible fraction: (€40,000 − €18,300) / 5 = €4,340 add-back for the year.
• Tax penalty recorded in accounts: €2,000 (not deductible, Art. 39-2 CGI).

Total add-backs: +€6,340

Deductions activated

• Provision for employment tribunal: formal notice received in October, solicitor instructed, documented assessment between €12,000 and €18,000 → provision set at €15,000, supported by the legal file (Art. 39-1-5° CGI).
• Accrued charges: advisory fees covering November–December, services rendered, invoice not yet received → €8,000 accrued (BOI-BIC-CHG-40).

Total deductions: −€23,000

Adjusted taxable profit

IS comparison

Without review (base €120,000):

• 15% × €42,500 = €6,375
• 25% × €77,500 = €19,375
• Total IS: €25,750

After review (base €103,340):

• 15% × €42,500 = €6,375
• 25% × €60,840 = €15,210
• Total IS: €21,585

IS saving: €4,165 — achieved without any additional expenditure, purely through rigorous documentation of pre-existing rights.

This type of review consistently produces IS differences of €3,000 to €12,000 for SMEs with profit between €80,000 and €250,000. The exercise is not about creating expenses that do not exist; it is about ensuring that legitimate deductions are not left on the table.

Note: the reduced IS rate of 15% applies to the first €42,500 of taxable profit for qualifying SMEs (turnover below €10 million, capital at least 75% held by individuals).

Discovering add-backs only at the tax return stage. The vehicle cap, non-deductible penalties, and similar items increase the IS base mechanically. Identifying them at closing date at least allows you to plan the cash outflow.

Creating provisions without contemporaneous documentation. A provision recorded in December without a document dated within the financial year will not withstand a tax audit. French fiscal doctrine requires precise facts at the closing date. Without a letter, court filing, legal opinion or formal estimate, the provision is legally fragile.

Missing accruals on recurring services. December rent paid in January, year-end advisory fees, prorated annual subscriptions: these charges are attachable to the year and must be accrued before the close.

Underestimating document collection lead times. Assembling the evidence for a valid provision — lawyer's letter, court filing, valued inventory — takes time. Starting the review six weeks before the closing date is a realistic operational minimum.

A structured review follows six steps:

1. Interim pre-balance sheet — extract a trial balance at month minus one or two to obtain a first estimate of expected profit.

2. Accrued charges inventory — list all contractual commitments in progress but not yet invoiced: rent, service providers, subcontractors, advisers.

3. Review of existing provisions — verify that each provision on the balance sheet remains justified, estimated, and documented. Provisions that are no longer warranted are reversed into profit.

4. New provisions — list risks that arose or became more precisely defined during the year: litigation, warranties, obsolete stock, doubtful receivables.

5. Add-back checklist — systematic verification of vehicles, fines, mixed-use expenses, and directors' remuneration.

6. IS simulation and trade-off analysis — compute expected IS with and without the identified levers, analyse the remuneration/dividend trade-off, and verify eligibility for the reduced 15% rate.

A pre-close tax review is a steering exercise, not a formality. It documents your rights, secures your deductions, and prevents unpleasant surprises at the liasse fiscale stage.
