Optimize the tax result before closing

Update April 2026 - Optimizing the tax result before closing cannot be improvised: it is prepared methodically, entry by entry, supporting document by supporting document. It is during this window — between the end of the financial year and the production of the tax return — that the company still has real leverage to secure its tax liability.

In short: Optimizing the tax result before closing involves reviewing déductible expenses, justified provisions, depreciation, doubtful debts and extra-accounting restatements, in order to reduce tax in strict compliance with the legal framework defined by the CGI and the BOFiP.

The tax result is not mechanically deducted from the accounting result. It is obtained after a series of restatements — reinstatements and deductions — that the company must identify before the bundle is frozen.

Once the déclaration of results has been submitted, any correction requires a corrective déclaration, with the additional controls and delays that this implies (impôts.gouv.fr — Déclaration of results).

Anticipating allows you to:

• Control the tax burden rather than incurring it;
• Secure each writing with solid documentation;
• Avoid adjustments linked to insufficiently justified charges;
• Preserve cash flow by choosing between rémunération and distribution.

The starting point for any optimization is understanding the gap between these two results.

The accounting result#

It reflects the economic performance of the company according to the rules of the general accounting plan (PCG). This is the number at the bottom of the income statement.

The tax result#

It is obtained by applying to the accounting result adjustments provided for by the General Tax Code (CGI):

• Reinstatements: charges deducted from an accounting point of view but not tax déductible (fines, lavish expenses, non-déductible portion of depreciation, etc.);
• Deductions: income taxed in accounting but tax exempt, or carry forward of previous déficits.

Understanding these mechanisms is the first step in controlled optimization. To learn more, consult our article Taxation and business taxes.

1. Exhaustive review of déductible expenses#

Each charge must be linked to the exercise and justified by supporting documentation. Before closing, systematically check:

• Charges to be paid (CAP): invoices not yet received but for which the service has been provided. The absence of invoicing does not exempt the charge from being recorded (BOFiP BOI-BIC-CHG-40).
• Products to be received (PAR): services invoiced but not yet recorded.
• Conversion differences: unrealized losses on receivables and debts in foreign currencies, to be provisioned before closing.

Supporting document required: invoice, purchase order, contract or any document establishing the reality and amount of the charge. In the event of an audit, the tax administration requires a set of matching clues.

2. Provisions: when and how to recognize them?#

Provisions for risks and charges (accounts 15) are tax déductible when they meet three cumulative conditions (article 39-1-5° of the CGI):

• Probable loss or expense: the event must be probable, not just possible;
• Reasonably estimable amount: a quantified range must be able to be documented;
• Event arising during the financial year: a future risk not attributable to the financial year cannot be provisioned.

Examples of regularly accepted provisions:

• Provision for ongoing labor dispute;
• Provision for depreciation of obsolete stocks;
• Provision for warranty given on products sold;
• Provision for restructuring decided before closing.

Please note: "convenience" provisions, without objective basis, are systematically reinstated during a tax audit. The BOFiP (BOI-BIC-PROV-10) requires a probability supported by concrete éléments.

3. Depreciation: leave nothing on the table#

Depreciation constitutes one of the most powerful – and most regulated – levers of tax optimization.

Check before closing:

• Unrecognized depreciation: an asset put into service but not yet depreciated must be retroactively depreciated;
• Exceptional depreciation: they allow accelerated depreciation in certain cases (BOI-BIC-AMT-20-20);
• The cap for passenger vehicles: the fraction of the acquisition price exceeding €18,300 (or €30,000 for electric vehicles) is not depreciable for tax purposes;
• Exceptional depreciation: certain devices (digital, ecological transition) entitle you to increased depreciation.

4. Bad debts: when to write off?#

A debt becomes tax déductible when it is definitely irrecoverable. Before closing:

• Identify customers in proven difficulty (collective proceedings, cessation of payment);
• Document the reminders made and the absence of recovery;
• Write off the receivable as a loss or set aside a provision for depreciation if irrecoverability is probable but not yet certain.

Tax clarification: a simple provision for doubtful debt is déductible if the doubt is substantiated. A definitive loss (abandoned debt) is directly déductible as an expense, subject to proof of the irremediable nature of the debtor's situation.

5. Compensation and distribution arbitrations#

At the end of the financial year, several decisions have a direct impact on the tax result:

• Executive rémunération: a reasonable increase, justified by the activity, remains a déductible expense for the company;
• Dividends vs reinvestment: the distribution of dividends is not tax déductible, unlike reinvestment in productive assets;
• Incentive and participation: these schemes give right to social and tax exemptions under conditions (BOI-BIC-CHG-30-10).

Certain errors systematically recur during tax audits:

• Expenses without invoice: an expense recorded without supporting documentation will be reinstated, plus penalties;
• Undocumented provisions: provisioning "just in case" without an objective élément exposes you to reinstatement;
• Forgotten or incorrectly calculated depreciation: an asset not depreciated during a financial year generally cannot be recovered subsequently without a corrective déclaration;
• Confusion between déductible and non-déductible expenses: fines, late payment penalties, sumptuary expenses are never déductible;
• Forgotten extra-accounting adjustments: form 2058-A requires the exhaustive list of reinstatements and deductions.

To avoid not missing key deadlines, consult our article Tax package submission deadline 2026.

A structured tax review generally follows these steps:

1. Accounting-tax reconciliation: verification that each expense recorded is tax éligible;
2. Inventory of restatements: list of reinstatements and deductions to be made on form 2058;
3. Review of provisions and depreciation: control of compliance with the BOFiP and the CGI;
4. Analysis of receivables and debts: identification of potential losses and conversion differences;
5. Year-end arbitrations: simulation of the tax impact of the différent options (rémunération, dividends, investment);
6. Documentation: creation of a traceable working file, ready in the event of an inspection.

Hayot Expertise Advice: The best optimization before closing is often the most discreet: a clean file, justified entries and decisions taken early enough to be fully documented.

We prepare the pre-closing review, identify sensitive items and secure arbitrations before producing the package.

Launch a pre-closing tax review

Optimizing the tax result before closing does not mean forcing the figure. It means making what needs to be reliable while there is still time to act usefully. Each charge reviewed, each provision documented, each depreciation verified reduces the risk of adjustment and contributes to a controlled tax charge.

Companies who anticipate this review — rather than treating it as an administrative formality — derive a double benefit: a legitimate tax saving and total peace of mind in the face of a possible tax audit.
