Taxation and business taxes: 2026 guide

Updated March 2026 - Business taxation is not just about corporate tax. A company must often manage several layers in parallel: VAT, IS, deposits, economic contribution, taxation of distributions, possible withholdings and additional reporting obligations. In 2026, the subject is not only to know each tax, but to organize their interaction.

Companies should generally monitor:

• ▸VAT;
• ▸read** ;
• ▸the CFE;
• ▸depending on the case, deductions, additional taxes or sectoral obligations;
• ▸and taxation linked to distributions or international flows.

VAT and IS concentrate the majority of calendar and reconciliation errors. This is particularly true when the accounting is not reviewed regularly or the cash flow is managed too late.

• ▸the impact of IS advance payments;
• ▸consistency between accounting results and tax results;
• ▸management of supporting documents;
• ▸documentation of intra-group flows;
• ▸the tax consequences of legal decisions.
