Tax audits and disputes
We support and represent you in the event of claims, regularization procedures, audits or disputes with the tax authorities, or before the courts in the event of an appeal.
Challenging a tax decision
Receiving an official tax assessment, a tax ruling or a tax reminder can raise a number of questions. These rulings can result from a number of situations: a tax return not filed on time, a discrepancy between the amounts declared and those retained by the tax authorities, or the subsequent discovery of tax items not initially taken into account.
Swiss tax law provides for the possibility of contesting such decisions within a strict 30-day time limit from the date of notification. Our team will be with you every step of the way, analyzing the basis for the decision, gathering the relevant supporting documents and preparing the arguments needed to defend your interests.
In the event of notification, it is essential that you contact us immediately, so that we can act quickly and effectively to protect your rights.
Regularize your tax situation
Tax regularization by spontaneous denunciation is a voluntary procedure that enables a taxpayer to declare undeclared income, assets or patrimonial property elements, thereby limiting additional tax and criminal penalties.
This possibility, provided for under Swiss tax law, is part of a context of increasing transparency between tax authorities – notably with the introduction of the automatic exchange of information (AEOI).
