If such guarantees are provided it is because the tax administration has a certain number of prerogatives in the event of conducting an accounting audit, it has a right of communication (particularly with third parties), this provision being provided for in article R13-1 of the LPF (Book of Fiscal Procedures).
With respect to an accounting audit, this procedure is conducted over several stages, initially even before deciding that an accounting audit will be carried out, the auditor shall collect a number of items. For this end, it will examine the files made available to the tax administration (tax declarations, e.g. annual tax returns, annual salary declarations, tax on company vehicles, VAT declarations, annual corporate documents such as minutes, reports of previous audits if there are any, local tax notices etc.).
