The tax burden of a company is not only reduced by choosing the tax regime or maximizing deductible expenses. The most profitable levers often lie in the fine management of VAT flows, the timing of amortizations, and the balance between remuneration and distribution, three areas we detail here.
Electronic invoicing and VAT management: the new area of tax optimization
Since September 1, 2026, all companies subject to VAT must receive electronic invoices via an approved platform. Large companies and mid-sized enterprises must also issue these invoices and transmit e-reporting data. This change profoundly restructures VAT management.
The standardization of data mechanically reduces declaration errors, and thus the risk of reassessment. We observe that the issue goes beyond compliance: the granularity of the collected data allows for the management of VAT credits in almost real time. A VAT credit recovered two months ahead of the usual schedule directly improves cash flow.
With the tax administration now having a digital mirror of your flows, inconsistencies between declared revenue and issued invoices will be detected much faster. Any tax optimization strategy that relied on approximate time delays becomes risky. Document rigor is no longer a luxury; it is a prerequisite.

Amortizations and provisions: tax calendar and smoothing of taxable income
The choice between linear and declining amortization is not just an accounting issue. Declining amortization accelerates tax deduction in the early years, which reduces corporate tax at a time when the investment weighs most heavily on cash flow.
We recommend mapping all depreciable assets at the beginning of the fiscal year to balance between the two methods according to the projected income profile. A company anticipating a very profitable year has an interest in increasing amortization allocations for that specific year.
Provisions for charges and risks
Provisions remain an underutilized lever. A provision for litigation, for inventory depreciation, or for customer guarantees is deductible from taxable income if it is justified and individualized. The condition is strict: the risk must be probable and quantifiable at year-end.
In practice, many companies fail to provision doubtful receivables or contractual guarantees, which artificially inflates their taxable income. A systematic audit of provisionable risks before year-end reduces the tax burden without any complex arrangements.
Exceptional contribution on the profits of large companies
The finance law has extended the exceptional contribution on the profits of large companies. This measure targets companies whose revenue exceeds a high threshold, with an additional rate added to the normal corporate tax rate.
For the affected companies, optimization involves a detailed analysis of the distribution of results among group entities. The parent-subsidiary regime and tax consolidation allow results to be consolidated and deficits of one subsidiary to be absorbed by the profits of another. This mechanism remains the most effective for smoothing the taxable base at the group level.
- Tax consolidation requires that the parent company holds at least 95% of the subsidiary’s capital and that the fiscal years are aligned.
- The parent-subsidiary regime exempts almost all dividends distributed, provided there is a minimum holding of 5% maintained for at least two years.
- Both regimes are cumulative but impose distinct reporting obligations that must be anticipated from the group’s structuring.
Balancing remuneration and dividends: impact on overall taxation
The remuneration of the manager is deductible from the company’s income, reducing the corporate tax base. Dividends, on the other hand, are paid after corporate tax and are subject to a flat tax or progressive scale on the manager’s side.
The appropriate balance depends on the manager’s personal marginal tax rate, the applicable corporate tax rate (reduced or normal rate), and the level of social charges on the remuneration. A manager of an LLC subject to the TNS regime bears social contributions on dividends exceeding 10% of the share capital, which radically changes the calculation compared to a president of a SAS.
Tax credits not to be overlooked
The research tax credit (CIR) and the innovation tax credit (CII) remain among the most generous schemes in the French tax system. The CIR covers a significant portion of eligible R&D expenses. We find that many industrial or technological SMEs underestimate their eligibility, particularly regarding personnel expenses allocated to research.
- Technology watch expenses are eligible for the CIR up to an annual cap.
- The CII concerns expenses for the design of prototypes or pilot installations of new products, with a narrower scope than the CIR.
- Both credits are declared on specific forms (2069-A for the CIR) and are subject to frequent controls: technical documentation must be prepared in advance, not at the time of control.
Reducing the tax burden relies less on sophisticated arrangements and more on management discipline: provisioning what needs to be, amortizing at the right pace, and documenting each tax credit. Synchronizing the remuneration strategy with the manager’s tax profile complements this approach, especially when data from electronic invoicing allows for real-time monitoring.
