It's the one status you can't give yourself. In Switzerland, neither you, nor your accountant, nor your clients decide that you are self-employed: an AHV compensation fund does. And it doesn't do so as a formality — it checks that you aren't, in practice, a disguised employee. For a sole proprietorship getting started, this is the step that determines everything else: contributions, invoicing, pension provision.
This guide sums up who decides, on what criteria, which documents to prepare and how much contributions will cost in 2026. For the broader context of Swiss social insurance, see also our FAQ on salaries and social charges.
Is it really worth registering as self-employed?
Before aiming for this status, ask yourself the real question: what does it bring you? Being self-employed opens up concrete tax advantages, but comes with obligations that aren't justified for a handful of isolated assignments. And remember: you don't decide on your own — the fund grants or refuses the status.
The advantages of genuine self-employed status:
- Deducting your business expenses: equipment, premises, travel, training, depreciation — costs that reduce your taxable income.
- The pillar 3a "large ceiling": without a 2nd pillar, a self-employed person can pay in up to 20% of net income (ceiling CHF 36,288 in 2026), versus CHF 7,258 for an employee. It's the main optimisation lever.
- Invoicing in your own name and building a client base; reclaiming VAT if you are liable (optional below CHF 100,000 in turnover).
- A sliding rate on modest incomes (from 5.371%).
The trade-offs not to overlook:
- Regular formalities: registration, quarterly instalments, bookkeeping, annual statement.
- A minimum contribution of CHF 530/year, due even with no profit.
- No unemployment insurance: the self-employed aren't covered by the ALV.
- A status that doesn't depend on you: the fund grants or refuses it.
Few assignments per year? Often not worth it
For a one-off assignment or fewer than three assignments a year, the administrative burden almost always exceeds the benefit — and the fund would likely refuse the status. The simplest route: have the commissioning company treat the amount as a salary and report it to its AHV fund. A secondary income not exceeding CHF 2,300 per year and per employer can even be exempted from contributions, on request. Self-employed status only becomes worthwhile if the activity is durable, generates deductible expenses or income sufficient to fund pillar 3a, and serves several clients.
Why you can't declare yourself self-employed on your own
As soon as you start a gainful activity on your own account, you must register with a compensation fund. The fund examines your situation and grants — or refuses — self-employed status. Until it is recognised, your income may be treated as a salary, with the corresponding contributions charged to whoever pays you. This recognition isn't a mere rubber stamp: it can be reassessed if your situation changes.
The criteria the fund examines
The fund seeks to establish whether you genuinely bear entrepreneurial risk or are economically dependent on a single principal. The decisive indicators are:
- Acting in your own name and on your own account, invoicing under your sole proprietorship.
- Bearing the economic risk: investments, fixed costs, risk of loss and of non-payment.
- Working for several clients: the most closely scrutinised indicator.
- Having your own premises, equipment or tools.
- Being free in how you organise your work: hours, methods, use of subcontractors.
The single-client trap
If almost all of your turnover comes from a single client, the fund sees economic dependence typical of a relationship of subordination. The likely outcome: refusal of the status, or reclassification as disguised employment. Diversify your assignments from the start and keep proof of that diversity.
Employed but doing a one-off assignment: do you need a sole proprietorship?
Already employed full-time and carrying out a single assignment for another company, with no intention of doing more? You don't need to set up a sole proprietorship or obtain self-employed status: a one-off activity doesn't meet the criteria anyway (no duration, no economic risk, no diversity of assignments). The simplest route is for the commissioning company to treat the amount as a salary and report it to its AHV fund. A commercial register entry only becomes mandatory from CHF 100,000 in turnover.
The registration dossier: which documents to provide
The more concretely your dossier demonstrates the activity, the faster recognition comes. Prepare:
- The signed contracts or mandates with different clients (or accepted quotes).
- The first invoices or quotes already issued under your sole proprietorship.
- Proof of your operating resources: premises lease, equipment purchases, website, professional liability insurance.
- Any commercial register entry (mandatory from CHF 100,000 in turnover).
- The registration questionnaire from the fund, duly completed.
AHV/IV/EO contributions of the self-employed
Once your status is recognised, you pay contributions to AHV, IV and EO on your determining income. The rate isn't fixed: it follows a sliding scale that eases the burden on modest incomes.
AHV/IV/EO contributions for the self-employed (2026)
| Annual determining income | AHV/IV/EO rate | Note |
|---|---|---|
| ≤ CHF 10,100 | Minimum contribution | CHF 530 per year, even with very low income. |
| Between CHF 10,100 and CHF 60,500 | 5.371% → 9.321% (sliding scale) | The rate rises gradually with income. |
| ≥ CHF 60,500 | 10.0% (full rate) | Excluding the fund's administrative costs. |
On top of these contributions come administrative costs that vary by fund. A key point for a sole proprietorship: there is no mandatory 2nd pillar for the self-employed. Your pension provision rests mainly on pillar 3a — a subject to plan for seriously, which we'll cover in an upcoming article.
Instalments and final settlement
You don't pay your contributions in one go at year-end. The fund bills instalments, usually quarterly, calculated on an estimated income. Once the tax assessment is communicated, it draws up the final statement and settles the difference one way or the other.
Estimate your income realistically
Setting your instalments too low may feel comfortable, but if your actual income clearly exceeds the estimate, default interest applies on the difference. As soon as a year looks markedly better or worse than expected, tell your fund so the instalments can be adjusted.
Checklist for a solid dossier
- Choose and contact a compensation fund (depending on your canton or sector).
- Gather your contracts and your first issued invoices.
- Demonstrate the diversity of your clients — avoid dependence on a single principal.
- Document your premises, your equipment and the economic risk you bear.
- Complete and submit the registration questionnaire.
- Plan your cash flow to absorb the quarterly instalments.
Invoicing several clients: your best proof
The best argument before the fund isn't a speech — it's a concrete trail of invoices addressed to several clients. That's where Bill Alps helps: issue clean, compliant QR-bills under your sole proprietorship, keep track of your clients and payments, and have on hand the exact history that documents your independence — useful both for the fund and for your bookkeeping.
- Self-employed status is granted by the AHV fund, never self-declared.
- Key criteria: own name, economic risk, several clients, own resources, free organisation.
- A convincing dossier rests on contracts and real invoices.
- 2026 contributions: sliding scale from 5.371% to 10%, minimum CHF 530/year.
- Plan for quarterly instalments and the absence of a mandatory 2nd pillar.
