Going self-employed in Switzerland (selbststaendig, indépendant, indipendente) means taking charge of three obligations an employer would normally handle: income tax across three levels of government, first-pillar social contributions, and, once you grow, value-added tax. This 2026 guide covers each one with current official figures so you can budget before your first invoice.
Who counts as self-employed
Your compensation office (Ausgleichskasse / caisse de compensation) decides whether you are genuinely self-employed. The tests are that you work in your own name and for your own account, bear your own economic risk, organise your own work, use your own infrastructure, and ideally invoice several clients. The decision is not yours to make by declaration: if you bill a single client, work on their premises with their equipment and take no economic risk, the office can requalify you as that client's employee, leaving the client owing back contributions. That is why many Swiss companies ask a new freelancer for the letter confirming self-employed status before they accept an invoice.
A Swiss sole proprietorship (Einzelfirma / raison individuelle) is not "founded" the way a GmbH is: it exists as soon as you trade. What you must do is register.
- Compensation office: register as soon as you start invoicing. You submit your first invoices and contracts, and the office issues the status decision and your provisional contribution schedule.
- Commercial register (Handelsregister): entry is mandatory once annual turnover reaches CHF 100,000. Below that it is voluntary, though it protects your business name.
- Federal Tax Administration (VAT): mandatory once turnover reaches CHF 100,000 over a rolling 12 months.
The same CHF 100,000 figure triggers both commercial register entry and VAT liability, so crossing it is a real administrative milestone rather than a rounding point.
Income tax: a three-layer stack
Switzerland taxes the net profit of a sole proprietorship as the owner's personal income. There is no separate business income tax; profit is added to any other personal income and taxed on your ordinary return, at three levels at once:
- Federal direct tax (DBST/IFD), identical everywhere in Switzerland.
- Cantonal tax, set by each of the 26 cantons under its own law.
- Communal tax, charged by your municipality as a multiplier of the cantonal tax.
The federal layer is modest and steeply progressive. The 2026 tariff for a single filer, published by the Federal Tax Administration, works like this:
| Taxable income (single, CHF) | Marginal rate on the next CHF 100 |
|---|---|
| Up to 15,200 | 0% |
| 15,300 to 33,200 | 0.77% |
| 33,300 to 43,400 | 0.88% |
| 43,500 to 58,000 | 2.64% |
| 58,100 to 76,200 | 2.97% |
| 76,300 to 82,000 | 5.94% |
| 82,100 to 108,800 | 6.60% |
| 108,900 to 141,500 | 8.80% |
| 141,600 to 185,000 | 11.00% |
| 185,100 to 794,000 | 13.20% |
| 794,100 and above | 11.5% flat on the entire income |
Two quirks matter. A federal tax bill below CHF 25 is not collected, so in practice nothing is due until roughly CHF 18,500 of taxable income. And above CHF 794,100 (CHF 941,500 for married couples) the tariff switches to a flat 11.5 percent on the whole amount, making 11.5 percent the federal ceiling.
How much the canton matters
Because two of the three layers are local, where you live changes your total bill dramatically for exactly the same profit. The table shows top marginal income-tax rates (federal plus cantonal plus communal, at the cantonal capital) for 2026, per the KPMG Swiss Tax Report 2026.
| Canton (capital) | Top marginal income-tax rate 2026 | Profile |
|---|---|---|
| Zug | 21.90% | Lowest in Switzerland |
| Schwyz | 23.30% | Low |
| Appenzell Innerrhoden | 23.66% | Low |
| Zurich | ~39.7% | Mid to high |
| Bern | 40.85% | High |
| Vaud | 41.50% | High |
| Basel-Landschaft | 42.22% | Very high |
| Geneva | 43.24% | Highest |
| Swiss average | 33.04% | Down from 33.15% in 2025 |
These are top marginal rates: your average (effective) rate is far lower, because the lower brackets are taxed lightly. At a taxable income around CHF 100,000, a single self-employed person typically pays effective total income tax in the low teens in a cheap commune and in the mid-twenties in an expensive one. Model your own commune with the Switzerland individual tax calculator rather than relying on the headline rate. One change on the horizon: on 8 March 2026 voters approved individual taxation of married couples, but joint filing still applies for 2026 and the reform takes effect by 2032 at the latest.
AHV/IV/EO, family allowances and the cover you do not get
This is the part that surprises newcomers. As an employee you pay half of first-pillar contributions and your employer pays the rest; self-employed, you pay the whole thing. Contributions to old-age and survivors' insurance (AHV/AVS), disability insurance (IV/AI) and loss-of-earnings compensation (EO/APG) are levied on net business profit at a maximum combined 10.0 percent (8.1 AHV, 1.4 IV, 0.5 EO). The 2026 figures published by the AHV/IV information centre are:
| Net annual profit (CHF) | AHV/IV/EO 2026 |
|---|---|
| Below 10,100 | Minimum contribution CHF 530 per year |
| 10,100 to 17,599 | 5.371% (bottom of the sliding scale) |
| 17,600 to 60,499 | Rises step by step toward 10% |
| 60,500 and above | Full 10.0% |
Your compensation office adds an administrative-cost surcharge of up to 5 percent of the contribution. Contributions are calculated on profit before this deduction, and the AHV/IV/EO you pay is itself deductible for income-tax purposes.
Two items belong in the same budget line. Family allowance contributions (FAK/CAF) are compulsory for the self-employed, typically 1 to 3 percent depending on canton and fund, levied on income up to CHF 148,200 a year. And the cover you do not get: the self-employed are outside unemployment insurance and are not subject to compulsory occupational accident insurance. Accident cover through your health insurer or voluntary Suva insurance, plus a daily sickness benefit policy, are the two gaps to close in month one.
VAT: the CHF 100,000 threshold
Value-added tax (MWST/TVA/IVA) enters the picture once your worldwide taxable turnover reaches CHF 100,000 over any rolling 12-month period. Hit that level and you must register with the Federal Tax Administration within 30 days. Below it, registration is voluntary but can pay for itself if you buy a lot of equipment and services carrying Swiss VAT, because registering lets you reclaim that input tax. Exempt supplies such as healthcare, education and cultural services do not count toward the threshold.
| Rate type | 2026 rate | Applies to |
|---|---|---|
| Standard | 8.1% | Most goods and services |
| Reduced | 2.6% | Food, water, books, medicines |
| Accommodation (special) | 3.8% | Hotel and lodging services |
Once registered you choose a method. The effective method means tracking output and input VAT line by line and filing quarterly. The net tax debt rate method (Saldosteuersatz) applies an industry flat rate to turnover instead, so you stop tracking input tax and file only twice a year. To use it, annual turnover including tax must not exceed CHF 5.024 million and annual VAT liability must not exceed CHF 108,000, which covers almost every one-person business. Since 2025 there is also an annual filing option for turnover up to CHF 5,005,000, with instalments during the year.
Deductions that move the needle
Taxable profit is turnover minus genuine business expenses: rent, materials, professional software, business insurance, business travel, depreciation, and the AHV/IV/EO contributions themselves. Three further levers matter most:
- Pillar 3a. With no occupational pension fund, you may pay in up to 20 percent of net earned income (profit after deducting AHV/IV/EO, before the 3a contribution), capped at CHF 36,288 for the 2026 tax year, and deduct the whole amount. With a pension fund, the 2026 cap drops to CHF 7,258. This is the strongest legal tax shield available to a Swiss sole trader.
- Occupational pension (second pillar). Joining voluntarily, through a professional fund or the substitute institution, converts profit into deductible retirement savings and opens the door to later buy-ins.
- Loss carry-forward. Business losses can be offset against profits for up to seven years, which is why a money-losing first year is worth declaring properly rather than ignoring.
Two worked examples
Lea, single graphic designer in the city of Zurich, CHF 90,000 net profit, no pension fund.
- AHV/IV/EO: profit is above CHF 60,500, so the full 10.0 percent applies: CHF 9,000, plus up to CHF 450 of administrative costs.
- Pillar 3a: 20 percent of CHF 81,000 (profit minus AHV) equals CHF 16,200, under the CHF 36,288 cap, fully deductible.
- Taxable income: CHF 90,000 minus CHF 9,450 minus CHF 16,200, so about CHF 64,350 before personal deductions such as health-insurance premiums.
- Federal tax: at CHF 64,300 the official 2026 tariff gives about CHF 799, an effective federal rate near 1.2 percent.
- Cantonal and communal tax: in the city of Zurich this is the dominant layer, in the order of CHF 8,000 to 9,000. Total income tax lands around 13 to 15 percent of taxable income.
- VAT: turnover is under CHF 100,000, so registration is optional.
Marco, single IT consultant in Geneva, CHF 180,000 net profit, no pension fund.
- AHV/IV/EO: 10.0 percent of CHF 180,000 equals CHF 18,000, plus up to CHF 900 of administrative costs.
- Pillar 3a: 20 percent of CHF 162,000 equals CHF 32,400, below the CHF 36,288 cap, so all of it is deductible.
- Taxable income: about CHF 129,600 before personal deductions.
- Federal tax: roughly CHF 5,093 on the 2026 single tariff.
- Cantonal and communal tax: Geneva is the most expensive canton and this layer dwarfs the federal one. Marco's effective income-tax rate is likely in the mid-twenties, versus low-to-mid teens for the same profit in Zug.
- VAT: turnover is well over CHF 100,000, so he is registered and, on the net tax debt rate method, files twice a year.
The lesson from both cases: the flat 10 percent AHV is the outflow people forget, and pillar 3a is the deduction that does the most work. Run your own numbers in the Switzerland individual tax calculator, and if profits climb toward CHF 200,000, compare the sole-proprietorship result against incorporating with the Switzerland corporate tax calculator.
Deadlines, payments and interest
Nothing is withheld at source, so the calendar matters.
| Obligation | When |
|---|---|
| Cantonal tax return (incl. business profit) | Usually 15 to 31 March following the tax year, extensions available on request |
| Cantonal and communal tax instalments | Provisional bills during the year, final settlement after assessment |
| Federal direct tax | Generally due 1 March following the tax year |
| AHV/IV/EO | Provisional instalments (usually quarterly), final adjustment once the tax assessment confirms actual profit |
| VAT, effective method | Quarterly, filed and paid within 60 days of period end |
| VAT, net tax debt rate method | Half-yearly, filed and paid within 60 days of period end |
| Late-payment interest on federal taxes and VAT | 4.0% per year from 1 January 2026 (4.5% in 2025) |
The AHV mechanism is the one that catches people. You pay provisional contributions based on an estimate, and later the compensation office recalculates against your assessed profit. A strong second year therefore produces a retroactive AHV bill on top of the current year's instalments. If income jumps, ask the office to raise your provisional instalments immediately rather than waiting for the correction.
Bookkeeping, setting money aside and common mistakes
A sole proprietorship with turnover below CHF 500,000 may keep simplified accounts: a record of income and expenditure plus a statement of assets and liabilities. Above CHF 500,000, double-entry bookkeeping is required. Either way, records and receipts must be kept for ten years, and a separate business bank account is close to mandatory in practice, because the tax office disallows expenses it cannot trace.
A realistic set-aside is 30 to 40 percent of every franc of profit: roughly 10 percent for AHV, administrative costs and family allowances, the rest for income tax adjusted for your canton. Park it in a separate account. VAT you collect is not income at all, and should be set aside on top.
The most common mistakes: assuming the compensation office will accept self-employed status with a single client; forgetting that VAT liability is tested on a rolling 12-month basis, not the calendar year; missing the pillar 3a payment deadline of 31 December (there is no retroactive top-up); mixing private and business spending; and budgeting for the 5.3 percent AHV that used to appear on a payslip instead of the 10 percent now owed.
Who this does not cover, and a closing note
This guide is about a Swiss-resident sole proprietorship. It does not describe a GmbH or AG, where the company pays corporate tax and you pay income tax on the salary and dividends you draw, a structure that often becomes attractive once profit is high and stable. It also does not cover cross-border commuters, people taxed at source, or lump-sum taxpayers.
The figures above are official 2026 rates and thresholds, but your exact liability depends on your canton, your commune, your marital status and your deductions. Use the calculators linked above to model your own numbers, and confirm your AHV status and any VAT obligation with your compensation office and the Federal Tax Administration. This guide is general information, not personal tax advice.
