Register a Company in Thurgau: Tax, Costs & Guide

Canton Thurgau sits on the southern shore of Lake Constance (Bodensee), bordering Germany to the north and positioned within easy reach of Austria to the east. With a population of roughly 280,000, it is a mid-sized canton that has built its economy on food production, precision manufacturing, and logistics rather than on financial services or corporate headquarters. For businesses that value low operating costs, competitive taxation, and direct access to the southern German and Austrian markets, Thurgau offers a combination that few Swiss cantons can match.

The canton’s effective corporate tax rate of approximately 13.4 per cent places it well below the Swiss average. Office and industrial rents are among the lowest in the German-speaking part of the country. Yet Frauenfeld, the cantonal capital, sits just 50 minutes from Zurich by train, and Kreuzlingen is directly adjacent to the German city of Konstanz. This balance between affordability and connectivity makes Thurgau a practical choice for production-oriented companies, cross-border traders, and cost-conscious founders who do not need a Zurich postcode.

This guide covers the full process of registering a company in Canton Thurgau: the commercial register, tax rates, key industries, and how the canton compares with its neighbours. For a broader view of the region, see the Zurich Region business guide or the main cantons overview.

What Does Canton Thurgau Offer Businesses?

Thurgau is bordered by Lake Constance and Germany to the north, Canton St. Gallen to the east and south, and Canton Zurich to the west. The canton’s geography is predominantly flat to gently rolling, which has historically favoured agriculture and, more recently, logistics and warehousing operations that require large floor plates at reasonable cost.

The canton’s economic structure leans towards the secondary sector (manufacturing, construction) to a greater degree than most German-speaking cantons. Roughly 30 per cent of employment is in industry, compared with a national average of around 20 per cent. This gives Thurgau a distinctive character: it is a canton where things are made, stored, and shipped rather than traded or financed.

How Does the Commercial Register Work in Thurgau?

The Handelsregisteramt des Kantons Thurgau, based in Frauenfeld, processes all company registrations, amendments, and deletions for the canton.

Contact Details

The Thurgau register handles a smaller volume of filings than Zurich or Zug, which can work in your favour: processing times are reliable, and the staff are accessible for queries. Standard GmbH and AG registrations are processed within five to fifteen business days.

Fees

Registration fees follow the federal schedule established by the Commercial Register Ordinance (HRegV):

Notary fees in Thurgau are regulated by cantonal ordinance and are generally at the lower end of the Swiss range. For a standard GmbH formation, expect notary costs of CHF 1,200 to CHF 2,000.

What Are the Corporate Tax Rates in Canton Thurgau?

Thurgau’s effective combined corporate tax rate of approximately 13.4 per cent makes it one of the more tax-friendly cantons in German-speaking Switzerland. While it cannot match the sub-12 per cent rates of Zug or Nidwalden, it undercuts Zurich by over six percentage points and sits below the Swiss average.

Tax Breakdown

Capital Tax

The canton levies an annual capital tax on equity at approximately 0.05 per cent. For a company with CHF 500,000 in equity, this amounts to CHF 250 per year.

Municipal Variation

The 13.4 per cent figure applies to Frauenfeld, the cantonal capital. Other municipalities apply different multipliers, though the variation within Thurgau is modest. Kreuzlingen, Amriswil, Weinfelden, and Arbon all fall within a range of roughly 12.8 to 14.0 per cent. Choosing the right municipality can shave a fraction off your tax bill, but the differences within the canton are far smaller than the gap between Thurgau and higher-tax cantons like Zurich.

What Are the Main Industries and Economic Strengths?

Thurgau’s economy is rooted in production, processing, and trade. The canton has three distinctive strengths that set it apart from its more service-oriented neighbours.

Food production and agriculture. Thurgau is Switzerland’s apple canton, producing roughly a third of the country’s apple crop. Beyond agriculture, the canton hosts a significant food processing cluster. Companies in dairy, beverages, confectionery, and convenience food operate production facilities here, drawn by the combination of agricultural supply chains, affordable industrial space, and proximity to German retail markets. The Thurgau food industry benefits from Switzerland’s strong reputation for quality while accessing the EU’s larger consumer base through established trade channels.

Manufacturing and precision engineering. The canton has a long tradition of metalworking, plastics processing, and machine building. Small and medium-sized enterprises (SMEs) form the backbone of this sector, with many family-owned companies supplying components to automotive, medical device, and industrial equipment manufacturers across the DACH region (Germany, Austria, Switzerland). Skilled manufacturing labour is more readily available and less expensive than in Zurich or the Basel region.

Logistics and warehousing. Thurgau’s flat terrain, motorway connections (A1 and A7), and border position make it a natural logistics hub. The availability of large industrial plots at competitive land prices has attracted distribution centres serving both Swiss and southern German markets. The proximity to the Konstanz border crossing enables efficient cross-border supply chain operations.

Emerging sectors. Clean technology, agricultural technology, and remote-first technology companies are a growing presence. The Startfeld programme, which operates across eastern Switzerland, provides mentoring, networking events, and access to early-stage funding for innovative businesses based in the region.

What Is the Bodensee Cross-Border Trade Advantage?

Thurgau’s position on Lake Constance gives it a geographic advantage that is difficult to replicate from an inland canton. The Bodensee region encompasses parts of Switzerland, Germany, Austria, and Liechtenstein, creating a cross-border economic zone with a combined population of roughly four million people.

Kreuzlingen-Konstanz. The towns of Kreuzlingen (Switzerland) and Konstanz (Germany) are directly adjacent, separated only by a border that has become increasingly seamless for goods and commuters. Companies registered in Kreuzlingen can maintain a Swiss corporate structure with its associated legal and tax benefits while being physically minutes from the German market.

Cross-border labour. Approximately 8,000 German and Austrian residents commute daily into Thurgau for work. This cross-border labour pool supplements the canton’s domestic workforce, particularly in manufacturing and technical roles. Wage expectations for cross-border commuters are typically lower than for Swiss-resident employees, which reduces payroll costs without compromising skill levels.

Trade corridors. The A7 motorway connects Thurgau to Ulm and Stuttgart via the Konstanz border crossing. The A1 links the canton westward to Zurich and eastward to St. Gallen. These corridors support efficient distribution to both Swiss cities and the southern German industrial belt.

For businesses targeting the DACH market from a Swiss base, Thurgau provides the shortest path between Swiss corporate advantages and German-Austrian customer proximity.

How Does Thurgau Compare with Neighbouring Cantons?

Thurgau vs Zurich: The tax saving is substantial. A company earning CHF 1 million in profit saves roughly CHF 63,000 per year in Thurgau compared with Zurich. Add the 60 to 70 per cent reduction in office rents, and total operating costs can be significantly lower. The trade-off is clear: Zurich offers unmatched access to talent, clients, and capital. Thurgau works best for businesses that do not require daily face-to-face interaction in Switzerland’s financial centre.

Thurgau vs Aargau: Aargau has a substantially larger economy and stronger manufacturing ecosystem but a higher tax rate (18.6 per cent versus 13.4 per cent). For production-oriented businesses, the choice often comes down to supply chain considerations and specific site availability rather than tax alone. Aargau’s proximity to Basel is an advantage for pharma suppliers; Thurgau’s border position favours companies focused on the German market.

Thurgau vs Schaffhausen: Both cantons offer similar tax rates and low operating costs. Schaffhausen is smaller and more compact, with a strong presence of multinational industrial companies. Thurgau offers a larger territory, more diverse industrial sites, and direct Lake Constance access. For most businesses, the choice depends on specific location requirements and industry clusters.

How Do You Register a Company in Thurgau Step by Step?

The registration process in Canton Thurgau follows the standard Swiss procedure. Here are the Thurgau-specific details.

1. Verify your company name. Search Zefix to confirm that your chosen name is not already in use across any Swiss canton. The Federal Commercial Registry Office (EHRA) has final authority over name approval.

2. Engage a Thurgau notary. Canton Thurgau uses publicly licensed notaries who draft the articles of association, prepare the formation deed, and handle submission to the Handelsregisteramt. Notary fees for a standard GmbH typically range from CHF 1,200 to CHF 2,000.

3. Open a capital deposit account. Approach a bank to open a blocked capital deposit account. The Thurgauer Kantonalbank (TKB) is the local cantonal bank and handles incorporations routinely. Deposit the full share capital: CHF 20,000 for a GmbH or CHF 100,000 for an AG (minimum 50 per cent paid in). Allow one to two weeks for account opening.

4. Execute the formation deed. All founders attend the notarial session or provide authorised representatives. The notary certifies the articles of association, director appointments, and any audit opt-out declaration.

5. Submit to the Thurgau commercial register. The notary files the complete application with the Handelsregisteramt in Frauenfeld. Expect processing within five to fifteen business days. Upon registration, the company receives its CHE number (UID) and appears in Zefix.

6. Complete post-registration formalities. Register with the Steuerverwaltung des Kantons Thurgau for corporate tax. Enrol with the cantonal social insurance office (SVA Thurgau) for AHV/IV/EO contributions. Arrange mandatory accident insurance (UVG) and occupational pension coverage (BVG) if you employ staff. Register for VAT with the Federal Tax Administration if annual revenue exceeds CHF 100,000.

Frequently Asked Questions

How long does it take to register a company in Canton Thurgau?

The Handelsregisteramt des Kantons Thurgau in Frauenfeld processes standard GmbH and AG registrations within five to fifteen business days after receiving a complete application. The entire formation process, from engaging a notary to receiving your confirmed register entry and CHE number, typically takes three to four weeks. Submitting complete, error-free documentation through a local notary who regularly works with the Thurgau register is the most reliable way to avoid delays.

What is the effective corporate tax rate in Canton Thurgau?

The effective combined corporate tax rate in Thurgau is approximately 13.4 per cent, covering federal, cantonal, and municipal taxes. This positions Thurgau in the lower third of Swiss cantons for tax burden, well below the national average of roughly 14.5 per cent. The exact rate varies slightly depending on the municipality. Frauenfeld and Kreuzlingen apply modestly different municipal multipliers, but the variation within the canton is narrow. Capital tax on equity is charged at approximately 0.05 per cent, which on a GmbH with CHF 100,000 in equity amounts to just CHF 50 per year.

Can I register a company in Thurgau if I live in Germany or Austria?

You can form and register a company in Canton Thurgau regardless of your nationality or country of residence. However, Swiss law requires at least one person authorised to represent the company to be domiciled in Switzerland. If you reside in Germany or Austria, you must appoint a Swiss-resident director or use a nominee director service. Many fiduciaries in Thurgau have specific experience serving cross-border entrepreneurs from the Bodensee region. Speak to an expert for guidance on structuring management to satisfy the residency requirement.

What are the advantages of registering in Thurgau rather than Zurich?

Thurgau offers three main advantages over Zurich. First, the corporate tax rate of 13.4 per cent is roughly six percentage points below Zurich's 19.7 per cent. On a CHF 500,000 profit, that equates to annual savings of approximately CHF 31,500. Second, office rents in Thurgau are 60 to 70 per cent lower than Zurich prime rates, with quality commercial space available from CHF 120 to CHF 200 per square metre per year. Third, industrial and warehouse space is readily available at competitive rates, which matters for manufacturing, logistics, and food processing businesses. The trade-off is a smaller local talent pool and less direct access to Zurich's financial services ecosystem.

Is Thurgau suitable for technology companies or startups?

Thurgau is increasingly viable for technology companies, particularly those that operate with distributed teams and do not require daily client meetings in Zurich. The Startfeld programme, active across eastern Switzerland, provides coaching, networking, and access to seed funding for early-stage companies. Office rents are a fraction of Zurich prices, which extends runway for bootstrapped startups. The canton's excellent fibre-optic infrastructure supports remote-first operations. However, if your business model depends on proximity to venture capital partners, talent from ETH Zurich, or a dense tech ecosystem, Zurich remains the stronger choice.

What documents do I need to register a company in Thurgau?

For a GmbH or AG formation in Canton Thurgau, you will need the following: notarised articles of association (prepared by a licensed Thurgau notary), a bank confirmation of the capital deposit, valid identification for all founders and directors (passport or Swiss ID), proof of the registered office address (a lease agreement or confirmation of domicile from a fiduciary), and specimen signatures for all persons with signatory authority. If any founder is a legal entity, you must also provide a certified extract from their own commercial register. The notary compiles and submits the full application package to the Handelsregisteramt in Frauenfeld.

Where is the Thurgau commercial register office located?

The Handelsregisteramt des Kantons Thurgau is located at Schlossmühlestrasse 9 in Frauenfeld. The office handles all company registrations, amendments, and deletions for entities domiciled in Canton Thurgau. Electronic filing from notaries is standard practice and accelerates processing. Existing register entries can be searched via the federal Zefix portal at zefix.ch.

What are the post-registration obligations for a new Thurgau company?

After receiving confirmation from the commercial register, a newly formed Thurgau company must register with the Kantonales Steueramt Thurgau for corporate income and capital tax purposes. If annual taxable turnover is expected to exceed CHF 100,000, VAT registration with the Federal Tax Administration is required. Companies that employ staff must register with the SVA Thurgau for AHV/IV/EO social insurance contributions, arrange mandatory accident insurance under UVG, and join a pension fund under BVG. The cantonal business register entry also triggers a SHAB (Swiss Official Gazette of Commerce) publication, which makes the company publicly visible.

Is Thurgau well positioned for cross-border trade with Germany?

Thurgau is one of Switzerland's best-positioned cantons for cross-border business with Germany. Kreuzlingen borders the German city of Konstanz directly, with no effective gap between the two urban areas. The Rhine marks the canton's northern border, with multiple crossing points into Baden-Württemberg. German-speaking throughout, Thurgau shares cultural and language compatibility with clients and suppliers across the border. Companies in trade, logistics, food processing, and manufacturing regularly use Thurgau as a base for serving the southern German market while benefiting from Swiss legal stability and comparatively low corporate taxation.

Does Thurgau's food production cluster offer advantages for agri-food companies?

Thurgau has one of the strongest concentrations of food production companies in Switzerland. The canton's agricultural base, combined with food processing, packaging, and cold storage infrastructure, makes it a natural home for businesses in the agri-food value chain. Major food producers have established production facilities in the canton, and the proximity to German and Austrian retail distribution networks reduces logistics costs. Cantonal support through Thurgau's economic promotion services includes assistance with site selection, introductions to the local supplier network, and guidance on available premises for food-grade production environments.
