How to Set Up a Sole Proprietorship in Switzerland: Costs, Commercial Register, Tax and AHV

You want to start working for yourself. Do you need to create a company? How much will it cost? Do you need to register in the Commercial Register? What happens with AHV? And do you need a separate business account?

For many people starting a business alone in Switzerland, a sole proprietorship is one of the simplest ways to get started.

There's no minimum share capital, you don't need a notary to create one, and unlike a GmbH, you don't need to establish a separate legal entity before you can begin doing business.

But simplicity doesn't mean you're free from administrative setup.

You still need to understand your personal liability, establish your self-employed status for social-security purposes,keep appropriate financial records and check whether Commercial Register and VAT registration apply to you.

Here's how it works.

What is a sole proprietorship in Switzerland?

A sole proprietorship is a business owned and operated by one individual. Unlike a GmbH or AG, it isn't a separate legal entity from its owner.

There is no minimum capital requirement, making it relatively straightforward to start, but there is also no legal separation between the business owner and the businessin the same way there is with a GmbH.

As the owner, you generally bear personal responsibility for the obligations of the business.

A sole proprietorship can therefore be particularly suited to people whose businesses are closely connected to their own work:consultants, freelancers, craftspeople and other independent professionals, forexample.

In fact, sole proprietorships are the most common company form in Switzerland, but being easy to start doesn't automatically mean it's the right structure for every founder.

Sole proprietorship vs GmbH: which fits?

The fundamental difference is legal separation.

With a sole proprietorship, you and the business aren't separate legal entities, but a GmbH is its own legal entity.

That affects capital, liability, administration and how you take money from the business.

The absence of minimum capital can make a sole proprietorship particularly attractive when you're testing a business idea or moving into self-employment without wanting to commit CHF 20,000 of company capital.

But don't choose solely on setup cost. Ask yourself:

• Will I work alone?
• How much financial risk will the business take?
• Could the business incur significant liabilities?
• Will I eventually bring in co-founders or investors?
• How important is legal separation between me and the business?
• How large do I expect the business to become?

The answers can help determine whether the simplicity of a sole proprietorship outweighs the advantages of establishing a separate company.

What does a sole proprietorship cost to set up?

One of the main advantages of a sole proprietorship is that there is no statutory minimum share capital.

You don't need CHF 20,000 as you would when creating a GmbH. You also don't need a notary simply to establish the business. That means the basic formation costs can be relatively low. But “no minimum capital” doesn't mean “no costs”. Depending on your circumstances, you may still have costs relating to:

• Commercial Register registration, if applicable
• professional or fiduciary advice
• insurance
• licences or permits required for your activity
• equipment and software
• business premises
• website and marketing
• accounting and invoicing
• your business financial setup

The more useful question therefore is: How much cash do I need to get the business operating properly?

For a consultant working from home, that amount might be relatively small. For a trades person who needs tools, a vehicle, insurance and stock before issuing thefirst invoice, it could be considerably more.

No minimum capital requirement means there is less formal financial friction at the beginning, it doesn't mean you don't need astartup budget.

Commercial Register: mandatory or optional?

Not every sole proprietorship has to enter the Swiss Commercial Register from day one.

Registration is generally mandatory for a sole proprietorship operated in a commercial form once annual turnover exceeds CHF 100,000.

Below that level, registration may still be possible voluntarily depending on the circumstances.

Why register voluntarily?

An entry can provide greater visibility and credibility when dealing with customers, suppliers and other organisations.Registration can also provide protection for the business name within the applicable scope.

But registration brings consequences too, including additional formal obligations. The important point is not to confuse Commercial Register entry with becoming self-employed; they aren't the same process.

Registering as self-employed with AHV

This is one of the most important parts of setting yourself up properly.

In Switzerland, you don't simply decide that you're self-employed for social-security purposes. Your status is assessed by the relevant compensation office. The assessment looks at how you work.

Indicators of self-employment can include operating externally under your own name, issuing your own invoices, bearing your own financial risk, organising your work independently and working for multiple clients.

No single label or document automatically settles the question.

This matters particularly for someone leaving employment to work as an independent consultant.

Imagine you leave your job on Friday and begin invoicing your former employer on Monday for effectively the same work, under very similar conditions. Calling yourself a sole proprietor doesn't necessarily make the relationship self-employment for AHV purposes. The working relationship matters.

If you're starting independently, contact the relevant compensation office and complete the process for recognition as self-employed.

Once recognised, you'll be responsible for your own AHV/OASI, IV/DI and EO/IC contributions.

What about pension and accident insurance?

Moving from employment into self-employment changes more than where your income comes from. It can also change your social-insurance position.

Self-employed people pay their own AHV/IV/EO contributions. However, they aren't automatically covered in the same way as employees.

Self-employed people aren't subject to compulsory unemployment insurance, mandatory occupational pension provision or compulsory accident insurance in the same way as employees. That means you need to consider what protection is appropriate for your circumstances.

For example,depending on your situation you may want to investigate voluntary accident cover, pension arrangements and other forms of insurance. And if your sole proprietorship later employs staff, you'll take on additional responsibilities as an employer.

Don't treat insurance and retirement provision as something to think about only once the business becomes successful, include them in your setup planning.

How does sole proprietorship tax work?

A sole proprietorship isn't a separate legal person from its owner. That means there isn't a separate corporate income tax return in the same way as for a GmbH. Instead,the business result forms part of the owner's personal tax position.

In simple terms, the income generated by your sole proprietorship, after allowable business expenses, contributes to your taxable personal income.

Business assets can also affect your personal wealth-tax position. The exact tax outcome depends on factors including your income, expenses, canton and municipality. This is one reason good record-keeping matters from the beginning.

You need to be able to distinguish business income and legitimate business expenses from your personal spending.

And remember that tax and VAT are different things.

Does a sole proprietorship need to register for VAT?

Being a sole proprietor doesn't automatically mean you're VAT-registered. VAT liability depends on the applicable VAT rules and turnover rather than simply your choice of legal form.

For most businesses, CHF 100,000 is an important threshold. A business is generally required to register for Swiss VAT when its relevant annual turnover reaches CHF 100,000, subject to the applicable rules and exceptions.

But don't confuse this with the CHF 100,000 Commercial Register threshold - they are separate requirements governed by different rules.

You may also be able to register for VAT voluntarily below the compulsory threshold.

How to setup a sole proprietorship step by step

Step 1: Decide whether a sole proprietorship is the right structure

Before doing anything else, make sure the structure fits the business you're building.

If you're working alone, have relatively straightforward needs and don't require legal separation between yourself and the business, a sole proprietorship can offer a simple route into self-employment.

If you're taking substantial financial risks,working with co-founders or planning outside investment, another structure maybe more appropriate.

Step 2: Decide how the business will present itself

Think about your business name and how you'll present yourself to customers. Specific rules apply to the naming of sole proprietorships, particularly where Commercial Register registration is involved.

Check the current requirements before committing money to branding, domains and signage.

Step 3: Start documenting your independent activity

Your compensation office will assess whether you're genuinely operating as self-employed.

Contracts, invoices, evidence of clients, business expenses, your website and other documentation can help demonstrate how you're operating.

Don't manufacture evidence simply to satisfy a checklist. The point is that your real activity should demonstrate independence.

Step 4: Apply for recognition as self-employed

Contact your relevant compensation office to establish your AHV status.

This is different from whether you're entered in the Commercial Register.

Step 5: Register in the Commercial Register if required

If your sole proprietorship meets the conditions requiring registration, including the applicable turnover threshold, complete the registration with the relevant cantonal Commercial Register.

If registration isn't mandatory, decide whether voluntary registration makes sense for you.

Step 6: Check your VAT position

Consider VAT from the beginning rather than wait in until you have already crossed a threshold. If you expect the business to generate sufficient relevant turnover, VAT liability can potentially apply from the start.

Step 7: Organise insurance and pension provision

Understand which protections no longer happen automatically when you move from employment to self-employment.

Consider accident insurance, pension provision and any insurance relevant to your profession and risks.

Step 8: Setup your financial administration

Before your first invoices start arriving and expenses begin accumulating, decide how you'll:

• issue invoices
• receive customer payments
• pay business expenses
• keep receipts and documents
• track income and costs
• prepare your accounting records
• monitor cash flow

This part is easy to postpone. It's also much easier to organise when there are ten transactions than when there are 1,000.

The next step: your business account

When business income arrives in the same account you use for rent, groceries, holidays and personal subscriptions, understanding what's happening in the business becomes harder than it needs to be.

Separating your business finances can make it easier to:

• see what the business is earning
• track expenses
• reconcile transactions
• prepare information for your accountant or fiduciary
• understand cash flow
• keep personal and business spending distinct

This becomes particularly useful at tax time, and it helps establish a good habit from your first customer onwards:

Treat the business like a business.

Your first invoice and first payment

Registering your business is an important step, but getting paid is where it starts to feel real.

Before sending your first invoice, make sure you understand what information it should contain, your payment terms and whether VAT applies to you.

Then think about what happens after you press send.

Ideally, the process should be simple:

invoice sent → payment due → payment received →transaction matched → records updated

This might feel excessive when you only have one or two customers, but creating a clear process early means you don't have to rebuild your financial administration when the business becomes busier.

When does it make sense to switch to a GmbH?

Starting as a sole proprietor doesn't mean you have to remain one forever.

The structure that makes sense when you're earning your first CHF 30,000 may not necessarily be the structure that makes sense once you're employing people, taking on larger contracts or building a business with substantial assets and liabilities.

A GmbH may become worth considering as the business grows and your priorities change.

Possible reasons for reviewing your structure include:

• increasing business risk or liabilities
• wanting clearer legal separation between personal and business
• assets
• bringing other owners into the business
• employing a growing team
• changing financing needs
• tax and succession considerations
• wanting a company structure better suited to future growth

There isn't one turnover figure at which every sole proprietorship should automatically become a GmbH. The right moment depends on the circumstances of the business and the owner.

If you're reaching that point, speak to a fiduciary or tax adviser and compare the implications before changing structure.

From self-employed to operational

Starting a sole proprietorship can be remarkably simple. Running one well requires a little more structure.

You need:

• customers
• to invoice them
• to get paid
• to understand your costs
• to keep money aside for obligations such as tax and social-security contributions
• enough visibility over your finances to know how the business is doing

That's why your financial setup matters from the first weeks, not just once the business becomes large enough to need an accountant.

Helvo helps bring your business account, payments,invoicing and financial management together in one place, giving you a clearer view of the money behind your business while reducing the number of separate processes you need to manage.

Starting the business should be simple. Understanding its finances should be too.

Frequently asked questions about sole proprietorships in Switzerland

When must I register my sole proprietorship in the Commercial Register?

Commercial Register registration is generally mandatory for a sole proprietorship operated in a commercial form once annual turnover exceeds CHF 100,000.

Below that threshold, voluntary registration may still be possible.

Commercial Register registration should not be confused with recognition as self-employed for AHV purposes.

How is a sole proprietorship taxed?

A sole proprietorship isn't a separate legal entity from its owner.

The business result therefore forms part of the owner's personal tax position rather than being taxed separately as the profitof a legal entity such as a GmbH.

The precise tax treatment depends on your individual circumstances and location.

How do I register a sole proprietorship with AHV?

You should contact the relevant compensation office to apply for recognition as self-employed.

The office assesses your actual working circumstances rather than simply accepting the legal label you give your activity.

Factors can include whether you operate in your own name, bear your own financial risk, organise your work independently and work for multiple clients.

Do I need a separate business account for a sole proprietorship?

A separate business account isn't automatically a legal requirement for every sole proprietorship.

However, separating personal and business transactions can make bookkeeping, tax preparation, cash-flow monitoring andeveryday financial management considerably clearer.

Do I need CHF 20,000 to start a sole proprietorship?

No - a sole proprietorship has no statutory minimum capital requirement.

The CHF 20,000 minimum capital requirement applies to a GmbH, not a sole proprietorship.

You should still calculate how much money you realistically need to start and operate your business.

Does a sole proprietorship need to register for VAT?

Not automatically.

VAT liability depends on your business activities and relevant turnover.

For most businesses, CHF 100,000 of relevant annual turnover is the key threshold, although the precise rules and exceptions need to be considered.
