Business Taxation: Taxes, Deductions and Optimization

Introduction

Business taxation constitutes one of the major strategic levers of an organization's financial performance. In France, the tax framework applicable to businesses is based on a complex set of rules stemming from the General Tax Code (CGI), the Monetary and Financial Code, and European directives. Between Corporate Income Tax (IS), Value Added Tax (VAT), social contributions and Economic Territorial Contribution (CET), managers must master a dense tax ecosystem to optimize their tax burden while scrupulously complying with legislation. This article provides a comprehensive overview of the main taxes, available tax deductions, applicable special regimes, and legal optimization strategies for 2024.

Corporate Income Tax (IS): Mechanisms and Rates

Corporate Income Tax applies by default to capital companies (SA, SAS, SARL) and, by option, to certain structures such as SCIs or EURLs. Since the progressive reform initiated by the 2018 Finance Act, the normal rate of Corporate Income Tax has been reduced to 25% for all fiscal years opened from January 1, 2022, in accordance with article 219 of the CGI.

SMEs benefit from a reduced rate of 15% on the first bracket of €42,500 of profits, subject to conditions: revenue less than €10 million and capital fully paid up and owned at least 75% by natural persons. Beyond this bracket, the normal rate applies.

The calculation of taxable income differs from accounting income: certain expenses must be added back (fines, non-deductible taxes, excessive gifts), while other income may benefit from preferential regimes (long-term capital gains taxed at 0% on equity stakes, parent-subsidiary regime exempting 95% of dividends received).

VAT: Collection, Deduction and Applicable Regimes

VAT, an indirect consumption tax, represents the largest source of tax revenue for the French State. The applicable rates are: 20% (standard rate), 10% (restaurants, renovation work), 5.5% (basic necessities, books) and 2.1% (reimbursable medicines, press).

The VAT mechanism allows the business to deduct the VAT incurred on its purchases (deductible VAT) from the VAT collected from its customers (collected VAT). The balance is remitted to the tax administration according to a variable frequency: monthly, quarterly or annually depending on the tax regime.

Three regimes coexist: the exemption from collection (exemption from VAT up to €91,900 of revenue for commercial activities), the simplified regime (annual revenue declaration CA12 with semi-annual installments) and the normal standard regime (monthly declaration CA3).

Tax Deductions and Strategic Tax Credits

Legal tax optimization is largely based on the judicious use of deductions and tax credits. The Research Tax Credit (CIR), codified in article 244 quater B of the CGI, allows deduction of 30% of R&D expenses up to €100 million, and 5% beyond. The Innovation Tax Credit (CII) extends this scheme to SMEs at 20% of innovation expenses.

Other levers exist: productive accelerated depreciation, corporate sponsorship (60% reduction of contributions within 0.5% of revenue), deduction of borrowing costs (capped at 30% of fiscal EBITDA according to the ATAD directive), and loss carryforward (forward without limitation of duration, backward over one fiscal year up to €1 million).

Legal Tax Optimization Strategies

Effective tax optimization combines several approaches: choice of appropriate legal structure, compensation/dividend arbitration for the manager, strategic activity location, and use of international tax treaties to avoid double taxation. Fiscal integration (article 223 A of the CGI) allows groups held 95% owned to consolidate their tax results, offsetting profits and losses of subsidiaries.
