Corporate tax in Switzerland
Corporate tax questions that cross cantonal borders
Swiss corporate tax questions rarely stay inside one canton. A company registered in Zürich, a group with entities in Genève and Lugano, or a holding structure sitting between Switzerland and the EU all raise the same problem: which rules apply, which authority decides, and who can act for you. Switzerland is a federal state of 26 cantons where substantive commercial law is unified but the administration of justice remains largely cantonal, and where court proceedings are conducted in German, French or Italian depending on the canton. Lawyers admitted in one canton may represent parties throughout Switzerland, so your adviser does not need to sit in the same city as your case. Tell us what you are dealing with — an assessment, a cross-border structure, a group reorganisation or a dispute — and we match you with a corporate tax lawyer in Switzerland who handles it.
Switzerland in practice
How corporate tax matters work in Switzerland
Two features shape almost every Swiss corporate tax file: the federal state’s 26 cantons and the country’s position outside the European Union. Below is how the framework actually operates, from the specialist federal courts to the deadlines that decide whether a challenge is admissible.
Where tax disputes are decided
Federal administrative matters are heard at first instance by the Federal Administrative Court in St. Gallen, while ordinary civil and criminal cases begin in district and cantonal courts. Appeals ultimately reach the Federal Supreme Court in Lausanne. An appeal against a federal administrative ruling must be brought within 30 days, which is why the file is usually built before the decision is issued.
One federal law, 26 cantonal court systems
Substantive commercial law is unified at federal level, but the organisation of the courts, the composition of the judiciary and the rules on court fees and party compensation remain largely cantonal. Since 2011 a single federal Civil Procedure Code has applied across the country, yet the same federal law is still applied through 26 different court systems, which shapes both timetable and cost.
The language of proceedings follows the canton
Switzerland has four national languages — German, French, Italian and Romansh — and each canton determines its own official language or languages. Proceedings are therefore conducted in German, French or Italian depending on the canton. For groups operating across Zürich, Genève, Lugano and Bern, filings, hearings and correspondence may run in more than one language.
Who may advise and represent your company
A lawyer must hold a cantonal practising certificate and be entered on the cantonal lawyers’ roll under the Federal Act on the Free Movement of Lawyers. A single admission is recognised nationwide, so a lawyer admitted in one canton may represent parties before judicial authorities throughout Switzerland. Cantonal supervisory authorities oversee the profession, with the FSA/SAV as the national umbrella body.
Costs, advances and party compensation
There is no single federal court-fee tariff for ordinary civil cases: cantonal tariff schedules apply, and fees are generally proportional to the value in dispute. As a rule the claimant pays an advance on court costs, and the unsuccessful party bears the costs of the proceedings. The court fixes party compensation under the cantonal tariff, while lawyers’ fees are freely agreed or set by cantonal schedules.
Cross-border structures and the Lugano Convention
Switzerland is not a member of the European Union and conducts its relations with the EU through a network of sectoral bilateral agreements. For cross-border civil and commercial litigation it is party to the Lugano Convention of 2007, which aligns the rules on jurisdiction and the recognition and enforcement of judgments with the EU’s Brussels I regime. That matters whenever a Swiss entity is sued, or sues, in an EU member state.

Typical situations
What clients bring to us
Most corporate tax files in Switzerland start with the same three uncertainties.
You do not know which canton decides
Your company is registered in one canton, your group has entities in others, and the authority that will assess or review the file is not obvious. Guessing wrong costs time, and deadlines run whether or not you were ready.
Cross-border exposure you cannot map
Payments, royalties or holdings touch an EU member state, and you need to understand jurisdiction and enforcement before a dispute starts. Switzerland is outside the EU, so the answer runs through bilateral agreements and the Lugano Convention rather than EU rules.
A file that spans more than one language
Your group files in German-speaking Zürich and French-speaking Genève, and the language of proceedings follows the canton. Documents, hearings and correspondence may need to move between German, French and Italian, and a single-language adviser can slow the whole matter down.

Questions
Frequently asked questions
How do I choose a corporate tax lawyer in Switzerland?
Start with the matter itself: an assessment dispute, a cross-border structure, an intra-group reorganisation or a canton-specific question. Lawyers admitted in one canton may represent parties throughout Switzerland, so location matters less than expertise. Tell us your situation and we match you with a corporate tax lawyer in Switzerland whose practice covers it.
Can a lawyer admitted in one canton represent my company in another canton?
Yes. Under the Federal Act on the Free Movement of Lawyers, a lawyer must hold a cantonal practising certificate and be entered on the cantonal lawyers’ roll, but that admission is recognised nationwide. A lawyer admitted in any canton may represent parties before judicial authorities throughout Switzerland. You are not tied to a lawyer sitting in the canton where the case is heard.
Do I have to be represented by a lawyer in Swiss proceedings?
In civil procedure there is no general obligation: parties may appear in person and may instruct any person capable of acting as their representative. Before the Federal Supreme Court, however, parties must be represented by an admitted lawyer in civil matters. In criminal proceedings the accused is entitled to a defence lawyer, and in serious cases defence counsel is mandatory.
How long do we have to challenge a federal administrative ruling?
An appeal against a federal administrative ruling must be brought within 30 days. Because the window is short and the formal requirements are strict, the file is normally prepared before the ruling is issued rather than after. Miss the deadline and that route to review can close.
How are court costs and lawyers’ fees handled in Switzerland?
There is no single federal court-fee tariff for ordinary civil cases; cantonal tariff schedules apply and fees are generally proportional to the value in dispute. As a rule the claimant pays an advance on court costs, and the unsuccessful party bears the costs of the proceedings. Lawyers’ fees are freely agreed or set by cantonal schedules.
Does Switzerland’s non-EU status affect cross-border disputes?
It does. Switzerland is not an EU member and conducts its relations with the EU through sectoral bilateral agreements. For cross-border civil and commercial litigation it is party to the Lugano Convention of 2007, which aligns the rules on jurisdiction and the recognition and enforcement of judgments with the EU’s Brussels I regime. That shapes how a dispute between a Swiss and an EU party is run.
