How to join a compensation fund as a self-employed person in Switzerland: criteria, steps, documents and AVS/AI/APG contribution rates.
Reading time: 12 min
A compensation fund is the body that collects your AVS, AI and APG contributions when you work on a self-employed basis in Switzerland. Unlike an employee, whose employer withholds and pays these contributions, a self-employed person must join a fund on their own, usually the fund of the canton where the business has its registered office, and then declare their income each year so that their contributions can be calculated. It is also this fund that decides, case by case, whether your activity really qualifies for self-employed status.
In brief
- Self-employed status is not automatic: the compensation fund recognizes it, case by case, on the basis of precise economic criteria.
- You join your trade association's fund if you are a member, otherwise the cantonal fund where you work, without delay once your activity starts.
- From CHF 60,500 of determining income, the AVS/AI/APG contribution rate is a flat 10%; below that, it follows a sliding scale.
What is a compensation fund?
A compensation fund is the body, cantonal or professional, responsible for collecting contributions to the Swiss 1st pillar: old-age and survivors' insurance (AVS), disability insurance (AI) and the loss of earnings compensation scheme (APG). It also keeps each insured person's individual account. In return, these contributions give entitlement to benefits: an old-age pension, disability benefits and loss of earnings compensation, depending on your situation.
As a self-employed person, you pay all of these contributions yourself. This personal responsibility is what most concretely distinguishes the self-employed from employees as far as social insurance is concerned.
There are two families of compensation funds in Switzerland. The cantonal funds, one per canton, accept anyone working on their territory. The professional funds are attached to a trade association and take in the members of that association first.
The choice between these two families changes nothing in the statutory contribution rates, which are set at federal level and are the same whatever the body. It mainly determines who you deal with administratively day to day, and sometimes additional services specific to a given professional fund.

Are you considered self-employed for AVS purposes?
Self-employed status is never acquired automatically just because you invoice for your services. The compensation fund assesses your situation as a whole against several criteria:
- Trading under your own business name: entry in the commercial register or a business directory, your own letterhead and advertising material, invoices in your name, registration for VAT where applicable.
- Bearing the economic risk of the activity: investments you finance yourself, your own operating resources, the risk of clients not paying, rent for your own premises.
- Organizing your business freely: you set your working hours, organize your work, can hand work over to third parties and choose the assignments you take on.
- Working for several clients: an activity carried out for several clients is generally considered self-employed, while working for a single client is generally an indication of employment.

The fund rules on your actual situation, not only on your contracts, and it assesses each activity separately: the same person can be recognized as self-employed for one activity and as an employee for another, in the same year. An architect employed part time in a firm can, alongside that job, build up a consulting activity for other clients: that second activity may be recognized as self-employed if it meets the criteria on its own, regardless of the person's employee status elsewhere. It is the activity that is classified, not just the person.
Owning your own company is a frequent source of confusion, and deserves a word of its own.
Common misconception
Running your own SA or Sàrl on your own is not enough: for AVS purposes, the shareholder or partner remains an employee of their own company.
Self-employed status has concrete consequences for your social cover. You are not insured against unemployment: this insurance is not open to the self-employed, not even on a voluntary basis. Accident insurance (LAA) and the 2nd pillar (LPP) are not compulsory for you: they remain optional and at your own expense if you wish to take them out.

How do you join a compensation fund when you become self-employed?
The affiliation process depends first on your sector of activity, then on the canton where you work.
- Check whether your trade has its own fund. If you are a member of a trade association with its own compensation fund, you join that fund directly.
- Otherwise, contact the cantonal compensation fund of the canton where your business has its registered office. Each canton has a single cantonal AVS fund.
- Gather the supporting documents that fit your situation: a commercial lease or management contract for the place of business, proof of equipment purchases for the capital invested, client invoices and contracts for the activity and business relationships, communication materials for marketing activities, an extract from the commercial register or official authorizations depending on your sector.
- Submit your application without delay once your activity starts. Some cantonal funds explicitly recommend doing so during the first quarter after launch, but this is not a single federal legal deadline: the exact deadline and the precise documents to provide depend on the fund concerned, so check directly with it.

Before submitting your file, gather all of these documents in one go rather than sending them one by one: this generally speeds up the fund's review of your application. Depending on your sector, some documents carry more weight than others: a lease will count for more in a craft business that needs premises, while client contracts and invoices will be central to a consulting activity without heavy equipment investment.
Once you have joined, this same fund will calculate your contributions every year, based on the income you declare.
How much do a self-employed person's contributions cost in Switzerland?
The social security contribution rates in Switzerland in 2026 depend directly on your annual determining income, that is, the income from your self-employed activity after certain adjustments.

On top of these contributions come administrative costs charged by the fund, which can reach up to 5% of the contributions due, as well as family allowance contributions, which are compulsory for the self-employed in every canton but whose rate varies from one canton to another. So do not rely on a single percentage for family allowances: check the one applied by your cantonal fund.
The obligation to contribute starts on 1 January following your 17th birthday. It ends when you stop your gainful activity for good; if you stop before the reference age, you continue to pay contributions as a non-employed person until you reach it. From the reference age (65, subject to transitional provisions for women born before 1964), which also opens entitlement to the AVS pension, you keep contributing if you keep working, but with an allowance: an allowance of CHF 16,800 a year applies to the income subject to contributions. Below that threshold, nothing is deducted; above it, only the remainder is subject to contributions on the usual scale.

The determining income used for this calculation needs a separate explanation.
Good to know
The AVS determining income is not simply your net taxable income: the fund starts from the net income in your tax assessment and adds back the personal AVS/AI/APG contributions you have already paid.
Before the contribution rate is even applied, notional interest on the equity invested in your business is deducted from your net income, that is, from your profit.
In practice, the fund often asks you for a provisional estimate of your income when you start, on which it calculates advance payments. These advance payments are then adjusted once your final tax assessment is known, which can lead to an additional amount to pay or, conversely, to a refund. Keep this mechanism in mind so you are not caught out by an adjustment during the year.
Self-employed or personnel leasing: what difference does it make to your contributions?
Joining a fund yourself as a self-employed person is not the only way to invoice for services in Switzerland, and it is not always the most suitable one.
A consultant who does not meet the economic criteria for self-employment, for example because they work for a single client without bearing any real business risk, runs the risk of the compensation fund refusing or challenging self-employed status. The activity can then be reclassified as employment, with consequences for the contributions due: the exact terms of this reclassification (who has to make up the difference, and for what amount) depend on the situation and should be checked with the compensation fund concerned.
This risk of reclassification explains why some profiles, particularly those who work long-term for a single client or with little freedom to organize their work, prefer not to register as self-employed themselves.
For them, personnel leasing provides employee status that complies with the law: a leasing company holding a cantonal license under the Federal Act on Employment Services and the Hiring of Services (LSE) hires the consultant and places them with the client, who gives the day-to-day instructions. The French term portage salarial, in common use, has no legal status in Swiss law, and it should not be confused with personnel leasing: according to the Federal Social Insurance Office, personnel leasing is ruled out for people who are genuinely self-employed, and simply declaring a freelancer who finds their own clients as an employee only creates a fictitious employee status that social insurance does not recognize. Our article on portage salarial in Switzerland explains this distinction.
Other arrangements, such as ANOBAG or the employer of record (EOR), meet similar needs but with different mechanisms and obligations. The choice between these options depends on your real situation: number of clients, degree of autonomy, investments made and tolerance for administrative risk.
None of these solutions spares you an individual review of your situation. Before deciding, it is useful to compare the administrative cost of each option, the social cover it provides and the level of reclassification risk associated with the way you currently work.
Key takeaways
Self-employed status in Switzerland is never a mere invoicing formality: it rests on economic criteria that the compensation fund checks case by case, with direct consequences for your contributions and your social cover. Joining early, gathering the right documents and understanding how determining income is calculated avoid most unpleasant surprises.
If any doubt remains about your situation, in particular if you are a shareholder in a company, if you work for a single client, or if you are hesitating between several possible statuses, the safest course is to ask your compensation fund directly before you invoice your first services. Recognition after the fact, several months into your activity, is generally harder to sort out than an affiliation checked from the start.
At Numeriq Payroll, we support Swiss SMEs, foreign companies, independent consultants and recruitment agencies with payslips, contracts, social contributions, compulsory insurance and LSE/SECO compliance. For consultants whose way of working does not meet the criteria for self-employment, a personnel leasing or employer of record solution remains an alternative worth considering, depending on their situation and objectives.
Frequently asked questions
What is a compensation fund?
A compensation fund is the body, cantonal or professional, that collects your Swiss 1st pillar contributions (AVS, AI, APG). It also keeps each insured person's individual account and, for a self-employed person, it is the fund that recognizes this status or not.
Can you be both employed and self-employed for two different activities?
Yes. Each activity is examined separately by the compensation fund, with its own contributions: the employer withholds those for the salaried job, while you declare the income from the self-employed activity yourself, provided that it meets the criteria set out above on its own.
What happens if your self-employed activity is very small?
For annual determining income below CHF 10,100, the minimum contribution is CHF 530 a year, even if your actual income is lower. If the activity is carried out as a sideline, with annual income of up to CHF 2,500, contributions are only collected at your express request: the fund does not claim them automatically below this threshold.
In both cases, the exact treatment depends on your precise situation, in particular whether your self-employed activity is your only source of income or a secondary activity alongside a salaried job. Ask your compensation fund directly to find out the procedure that applies to your case.

What do you risk if you pay AVS contributions late?
Late payment of contributions triggers default interest of 5% a year, added to the contributions due. The rules on default interest are set at federal level and apply in the same way to every fund; the payment deadlines that apply to you depend on your file.
To avoid this kind of trouble, it is best to plan ahead: as soon as you join, ask your compensation fund about the payment deadlines that apply to your file, and report any temporary difficulty without waiting rather than letting arrears build up.
