You don't start a sole proprietorship in Switzerland by filling out a form — you start by sending your first invoice. Only after that do you register with the AHV compensation fund (Switzerland's old-age and disability insurance), enter the Commercial Register (mandatory from CHF 100,000 turnover), and become liable for VAT (also from CHF 100,000). Here's what you actually need, in the right order.

This is the most important thing nobody at the bank, the Commercial Register, or the notary's office told us when we started out in 2021. Most websites on the topic begin with the business plan and end with the tax advisor. Real life looks different. You start with a customer, write a professional invoice, and only then register with the right offices. This article walks you through that practical sequence — with the actual CHF thresholds, real processing times, and the pitfalls that can cost you money.

Key Takeaways

• You don't need any upfront registration to become self-employed in Switzerland. The AHV recognises your self-employed status based on invoices to at least two or three different clients.
• Only once your annual turnover hits CHF 100,000 does the Commercial Register entry (CHF 120) and VAT registration become mandatory.
• Simplified bookkeeping (the so-called "Milchbüechli" cash-basis accounting) is allowed until your turnover exceeds CHF 500,000.
• In practice, AHV recognition as self-employed takes 8 to 12 weeks from when you submit your documents.
• Setup costs range from CHF 0 (DIY via EasyGov) to around CHF 600 if you use a notary or a setup service.

What is a sole proprietorship, exactly?

A sole proprietorship (Einzelfirma or Einzelunternehmen in German) is the simplest legal form in Switzerland. A single individual runs the business in their own name, with unlimited personal liability and no minimum capital. The business name must include your family name, optionally with an industry descriptor or made-up addition.

Switzerland has more than 300,000 active sole proprietorships. According to the Institute for Young Entrepreneurs (IFJ), around a third of all new businesses are registered as sole proprietorships — over 27,000 new entries in the first half of 2024 alone. It's the standard legal form for freelancers, the self-employed, and small service providers.

The key features at a glance:

• No minimum capital required (unlike a GmbH at CHF 20,000 or an AG at CHF 100,000).
• Personal liability with your private assets.
• Taxes flow through your personal tax return, not a separate corporate tax.
• Commercial Register entry only mandatory from CHF 100,000 annual turnover.
• Simplified bookkeeping allowed as long as turnover stays under CHF 500,000.

The Swiss way: work first, register later

Here's the point most guides get wrong or explain too late. In Switzerland, you don't become self-employed by filing an application — you become self-employed by actually doing the work and invoicing clients. The AHV compensation fund only recognises your status retroactively, once it can see that you're genuinely working at your own risk and for multiple clients.

Picture Marc, a fictional web designer in Zurich. Marc wants to freelance full-time. Instead of filing paperwork, he lands three small clients, writes three clean invoices with his name, address, and a short description of services. Only then does he register with his canton's compensation fund and submit copies of those three invoices. That's the same path most successful Swiss freelancers have taken. Including us.

This sequence has a practical advantage: you don't waste time or money on a registration before you know whether your idea actually finds customers. If the first contract never lands, you have no obligations, no open memberships, and no paperwork legacy.

Tip from experience: As soon as you write your first invoice, you'll need a professional tool for it. Magic Heidi sends your first Swiss invoice in under two minutes and is free to use without a credit card.

The AHV's 3-client test

The AHV compensation fund wants to see that you're working independently in economic terms. Concretely that means: at least two or three different clients, your own infrastructure (laptop, workspace, insurance), invoices issued in your own name, and bearing the entrepreneurial risk yourself.

If you only have a single client, you'll quickly be flagged for "false self-employment" (Scheinselbständigkeit). That's not just a theoretical issue. The AHV can refuse to grant you self-employed status, your client may end up owing back social charges, and you remain legally classified as an employee. If you start out with only one big client, find a second smaller one quickly. Even five hours of consulting per month is often enough to set things straight.

Obligations kick in at the threshold levels

This table is the shortest version of every Swiss threshold you need to know as a sole proprietor:

Keep this table close. It saves you 90 percent of the usual debates with fiduciaries.

Eligibility: who can start a sole proprietorship in Switzerland?

Almost any individual with residency in Switzerland can start a sole proprietorship. The conditions are clear, but they vary depending on your residency status.

Swiss citizens and C-permit holders

If you're a Swiss citizen or hold a C settlement permit, there are no specific administrative hurdles. You register with the compensation fund, enter the Commercial Register if needed, and get going.

EU/EFTA citizens

You need a valid residence permit (B or C) and a Swiss address. Self-employment is not a special case under the Free Movement of Persons agreement, but your cantonal migration office wants to be informed when you start a self-employed activity.

Third-country nationals

This is where it gets more complicated. If you're from a non-EU/EFTA country, you'll usually need a separate permit for self-employed activity, often combined with requirements about your business model, investment volume, and contribution to the Swiss economy. Talk to your canton's migration office early. Cantonal practice varies considerably.

Regulated professions

Certain activities require a professional licence regardless of legal form. These include doctors, lawyers, fiduciaries with a FINMA mandate, architects in some cantons, vets, and certain skilled trades that require a master craftsman certificate. The SME portal overview lists the main free and regulated professions.

How to register as self-employed in Switzerland: 7 steps

Here's the checklist for how it actually works. Not the textbook 12-point plan, but the order that works in practice.

Step 1: Write your first invoice

Before applying anywhere, find one or two paying clients and issue invoices. A Swiss invoice needs: your name, your address, the client's address, an invoice date, a description of services, the amount in CHF, and ideally a Swiss QR code for payment. That's it. If you're not yet VAT-registered, state that explicitly on the invoice.

Need a template, or want to set up your tool properly from day one? Take a look at our comparison of the best invoicing software for Swiss freelancers — it lays out the main options with their strengths and weaknesses.

Step 2: Pick a clean business name

The rule is simple: a sole proprietorship must include your family name. Examples: "Müller Webdesign", "Sarah Keller Coaching", "Atelier Rossi". You can add an industry term, a creative element, or your first name, but the family name is mandatory. Before registering with the Commercial Register, check on zefix.admin.ch whether the name you want is available and whether similar spellings already exist.

Pro tip: pick a name that still fits if you specialise in five years. A name that's too narrow (e.g. "Müller Wordpress Service") gets expensive to change once you want to offer more.

Step 3: Register with the AHV compensation fund

Once you've issued two or three invoices, register as self-employed with your canton's AHV compensation fund. You fill out a form, attach copies of your first invoices, briefly describe your business model, and confirm that you bear the entrepreneurial risk.

Processing takes 8 to 12 weeks in practice, sometimes longer. You can and should keep working normally during that time. The AHV recognises you retroactively once your documents are reviewed and issues a written confirmation of self-employed status. That confirmation is your most important document: banks, insurers, landlords, and clients can all ask to see it.

The AHV contribution rate in 2026 sits between 5.371% and 10% of your net profit, scaled by income. On a net profit of CHF 80,000 you'd pay around CHF 8,000 in AHV per year. These contributions are deductible as a business expense.

Step 4: Check whether you're liable for VAT

As long as your worldwide annual turnover is under CHF 100,000, you're not liable for VAT. You issue invoices without VAT, skip quarterly filings, and don't need a VAT tool. Once you cross the threshold, you have 30 days to register with the Federal Tax Administration (ESTV).

There's an important exception: voluntary registration. If you carry a lot of business expenses with VAT (software, hardware, travel), you can register voluntarily and reclaim input VAT. For a designer with CHF 30,000 turnover and CHF 8,000 in business expenses, that can mean several hundred francs per year. Our guide to VAT accounting in Switzerland explains the choice between the effective method and the flat-rate (Saldosteuersatz) method with examples.

Step 5: Decide on the Commercial Register entry

Below CHF 100,000 in annual turnover, the Commercial Register entry is voluntary. Above CHF 100,000 it becomes mandatory. The entry costs a one-off CHF 120 (federal fee, with possible additional cantonal costs) and gives you two practical advantages: clear external existence and protection of your business name within the canton.

You can do the entry yourself for free at einzelfirma.easygov.swiss, the federal online portal. Processing takes 5 to 15 working days depending on the canton. Notarised signatures are not always required — many cantons accept digital signatures.

Step 6: Sort out your insurance

Which insurances are actually mandatory and which are merely recommended is one of the biggest sources of confusion. Here's the practical list:

Mandatory:

• AHV/IV/EO (once recognised by the compensation fund).
• Health insurance (basic coverage, like everyone living in Switzerland).

Not mandatory, but usually wise:

• BVG / 2nd pillar (always voluntary for the self-employed — join via a professional association or the Substitute Occupational Benefit Institution / Stiftung Auffangeinrichtung BVG).
• Professional liability insurance (CHF 250 to CHF 1,500 per year depending on the field).
• Daily sickness benefits insurance (between CHF 1,000 and CHF 4,000 per year, depending on the waiting period).
• Accident insurance (often available as an add-on through your health insurer).

Optional, often unnecessary in the early years:

• Legal expenses, cyber, contents, etc.

Start with professional liability, especially if you do consulting or creative work. Build out the rest once your business is stable.

Step 7: Set up your invoicing tool

That completes the formation. What follows is running the business, and on day one that needs exactly one decision: how you issue invoices and where your receipts land. Switching mid-year is painful, so 30 minutes upfront pay off here.

Everything else about running the business is deliberately outside this formation guide:

• What the bookkeeping obligations actually are, what the monthly routine covers and how private withdrawals work: sole proprietorship accounting in Switzerland
• Which tool fits you and how the Swiss providers differ: Swiss accounting software

Sole proprietorship costs: what do you actually pay in Switzerland?

The practical answer: between CHF 0 and CHF 600, depending on how much you do yourself and whether you enter the Commercial Register.

The pricier options are rarely necessary. If your business model is simple and you don't need bespoke contracts, the DIY route via EasyGov works perfectly well. Save your money for professional liability insurance and a good bookkeeping tool.

When do I need to register as self-employed?

You need to register as soon as you're issuing invoices to clients on a recurring basis and the activity is intended to last. In practice that means: after your first two or three invoices, or once you plan to earn more than CHF 2,500 net per year. A one-off invoice doesn't trigger any registration.

The most important deadline is this: once you achieve "self-employed" status, your social charges start running. The AHV calculates retroactively from the date of your first business activity. If you've waited six months, you'll get a bill covering six months. It saves stress to register quickly after your first invoices.

A fictional example: Sarah, a fictional coach in Bern, starts in March, lands two clients, and writes five invoices totalling CHF 8,000. In May she registers with the AHV. In July her recognition comes through. She pays AHV contributions retroactively from March on her actual net profit, which on this volume is a few hundred francs. If she'd waited a year, she would have received a single annual bill of around CHF 1,200, plus interest for late payment.

AHV, BVG, and insurance: what's actually mandatory

Swiss social insurance is the topic that scares freelancers most. The reality is manageable. You pay less than an employee, but you also have less protection. Once you understand that, you can plan accordingly.

AHV/IV/EO is mandatory

Once you're recognised, you pay AHV/IV/EO on your net profit. In 2026, the contribution rate is between 5.371% and 10%, scaled by income:

• Net profit under CHF 10,100: minimum contribution CHF 530 / year.
• Net profit CHF 10,100 to CHF 60,500: gradually rising from 5.371% to 10%.
• Net profit over CHF 60,500: full rate of 10%.

For a fictional IT consultant like Marco in Zug with CHF 120,000 net profit, that's CHF 12,000 in AHV per year. For a fictional web designer Anna in Zurich with CHF 50,000 net profit, it's around CHF 4,200. These contributions are fully deductible as a business expense, which lowers your tax bill.

BVG: always voluntary for the self-employed

Sole proprietors are exempt from the BVG obligation, regardless of income. You can sign up voluntarily — either through a professional association or through the Substitute Occupational Benefit Institution (Stiftung Auffangeinrichtung BVG). The BVG only becomes mandatory for you once you yourself employ staff whose salary reaches the entry threshold.

Pro tip: even without BVG, Pillar 3a is worth it. Up to CHF 7,258 per year (2026) is deductible if you have a pension fund, and up to 20% of net profit (max CHF 36,288) for self-employed people without a pension fund.

Accident insurance: often misexplained

Self-employed people are not subject to UVG (mandatory accident insurance). You're covered for accidents through your health insurer (with an add-on, if you've requested one). Separate accident insurance isn't required, but it can make sense for self-employed people doing physical work.

Taxes as a sole proprietor: what you actually pay

There's no separate corporate tax. Your business result flows directly into your personal tax return. Your net profit (turnover minus business expenses minus AHV contributions) is added to your other income and taxed at your canton's ordinary rate. That's much simpler than running a GmbH, but it can be more expensive at very high incomes.

Deductible expenses include anything that's business-related: office rent or a home-office allowance, computer, software, travel, training, phone, professional liability, AHV contributions, Pillar 3a (proportionally), meals with clients. Keep receipts for everything. Swiss tax authorities generally accept a digital photo or PDF, as long as the date, amount, and issuer are visible.

If sorting receipts manually is a chore: Magic Heidi's AI receipt scanner automatically extracts the date, amount, VAT, and vendor — you just take the photo.

Self-employed on the side in Switzerland: special case with pitfalls

Many people start their self-employment alongside a regular job. That's legal and often tax-efficient, but it has two quirks. First: as soon as your side income exceeds CHF 2,500 / year net, side-job freelancers also need to register their self-employed activity with the AHV compensation fund. You then pay AHV separately on the side income.

Second: your main employer usually doesn't need to approve, as long as your employment contract doesn't have clauses against competing activities. Check your contract upfront, not your boss. If your contract includes a duty of loyalty or a non-compete, that can cause problems.

A fictional example: Lukas works 80% as a mechanical engineer in Aarau and does consulting on the side for family-owned businesses. After two years, the side income brings in CHF 30,000. He registers with the AHV, pays additional AHV on that amount, but can deduct all business expenses (laptop, software, client travel). He benefits tax-wise because his effective business expense ratio is around 25%. Once the side income reaches CHF 60,000 and is stable, Lukas starts thinking about going full-time.

Self-employed without capital: is it really possible?

Yes, with no caveats. A sole proprietorship has no minimum capital. You don't need a blocked account like with a GmbH (CHF 20,000), and you don't need an investor. What you do need are first clients and some liquidity to bridge the first two or three months until invoices are paid.

The risks deserve a realistic look. You're personally liable with your private assets for business debts. If you own a home or have meaningful savings, don't skip professional liability insurance, and consider switching to a GmbH early on (once net profit is consistently above CHF 100,000).

In practice, the most common first-year expenses are:

• Laptop or software: CHF 2,000-4,000
• Professional liability: CHF 250-1,500
• Tools and subscriptions (bookkeeping, hosting, Adobe, etc.): CHF 1,000-2,500
• AHV advance payments (based on estimate): CHF 2,000-8,000
• Optional: first website, business cards, advertising CHF 500-2,000

You don't need more than that to begin with. Don't let anyone push you into loans or fancy office tours before your business is stable.

When switching to a GmbH makes sense

The rule of thumb: from a stable net profit of CHF 100,000 to CHF 120,000 per year, switching to a GmbH often pays off — mainly for liability and tax reasons. A GmbH with CHF 20,000 minimum capital protects your private assets, lets you pay yourself a salary (with social-insurance benefits), and lets you retain profit inside the company. The conversion costs CHF 1,500 to CHF 4,000 with notary and fiduciary.

Stick with the sole proprietorship if you're under CHF 80,000 net profit per year, have a simple business model, and want to avoid the complexity of a GmbH. Above CHF 120,000, the GmbH usually becomes the better solution. Between CHF 80,000 and CHF 120,000 there's a grey zone where a quick consultation with a fiduciary saves money.

The most common mistakes when starting a sole proprietorship (from real cases)

From conversations with hundreds of Swiss freelancers, the same mistakes keep coming up:

These mistakes cost money, but they're all avoidable. Set yourself up properly at the start, and the rest runs itself.

Your next step

Starting a sole proprietorship in Switzerland isn't hard, but the right sequence saves you money and stress. First the invoice, then the AHV registration, then Commercial Register and VAT if needed. Keep the thresholds in mind (CHF 100,000 for Commercial Register and VAT, CHF 500,000 for double-entry bookkeeping), sort your insurance pragmatically, and set up your bookkeeping tool properly from day one.
