There is a figure that almost everyone knows: the price per appointment. And there is a figure that almost nobody knows: what actually remains in the account twelve months later, after tax assessment and contribution notice. Between these two figures lies the entire difference between a side income that saves a budget and one that above all costs time.
This text is not about why people in Switzerland are looking for a second income in 2026. It is about how to calculate it correctly – with the rules that apply from January 1, 2026.
The Starting Point: 2026 Is a Year When the Difference Grows Larger
Three developments converge in the current year. First, health insurance premiums: The average premium rises by 4.4 percent in 2026 to CHF 393.30 per month, for adults to CHF 465.30. Depending on the canton, the increase is between 3.0 and 7.1 percent – Zug is an exception with a reduction, not the rule.
Second, wages: Swiss companies plan for approximately one percent more in 2026. With expected inflation of around 0.5 percent, a real increase of half a percent remains. Premiums are not included in the national consumer price index – the statistics thus show a real wage gain, while the household budget feels a loss.
Third, the labor market itself: In 2025, 377,000 employed persons stated that they engaged in more than one job. That is 8.1 percent – in 1991 it was 4.1 percent. Women are affected much more at 10.5 percent than men at 5.8 percent. The second job is long since no longer a marginal phenomenon, but a structural feature of Swiss work biographies.
In this landscape, a side job in sex work is one of several options – and the only one where the hourly rate on paper lies so far above the usual second job that the calculation is rarely done cleanly. That is precisely the problem. We have described the motives behind it elsewhere: when the end of the month regularly comes before the paycheck, the yardstick shifts. Here we address what comes next: the arithmetic.
Fixed Point 1: The AHV Does Not Decide What You Earn – It Decides Who You Are
The first misconception concerns the exemption threshold. Since January 1, 2025, the compensation office collects contributions on net earnings from side income up to CHF 2,500 per year only upon request. The threshold was raised from the previously applicable CHF 2,300, and it applies per year, not per job or per client.
The word exemption threshold is crucial. It is not a tax deduction. Anyone who achieves CHF 3,000 net earnings pays contributions on CHF 3,000 – not on the 500 francs above the threshold. The jump at the threshold is therefore abrupt, not gradual.
Above that, the following key figures apply for 2026 for the self-employed:
- Full contribution rate: 10.0 percent (AHV 8.1 / IV 1.4 / EO 0.5) on earned income
- Declining scale for income below CHF 60,500: the rate rises from 5.371 percent at CHF 10,100 in stages to the full rate
- Minimum contribution: CHF 530 per year
- Plus an administrative cost contribution from the compensation office of a maximum 5 percent of contributions
The second and more important point: Whether an activity is considered self-employed is not decided by the person concerned, but by the compensation office – based on criteria such as own market presence, entrepreneurial risk, and independence. In the sex industry, this review is particularly relevant because many work arrangements lie in a gray zone between rental and employment. The canton of Bern, for example, explicitly states for the migration law area that self-employed activity in the sex industry is only possible if the service is provided outside a business premises and no third party issues instructions. Anyone working in a salon with fixed hours of presence, set prices, and revenue sharing may not meet these criteria – with consequences for the business’s contribution obligations and for one’s own status.
For side income, this means: The AHV registration is not optional paperwork, but the point at which the activity takes on legal form. It creates contribution years, closes gaps in the first pillar, and provides evidence that landlords, banks, and authorities will later require.
Fixed Point 2: There Is No Tax Exemption Threshold
The CHF 2,500 of the AHV are regularly confused with a tax exemption threshold. There is none. Income from side work must be declared from the first franc, less business-related costs.
The more expensive part is tax progression. A second income is not taxed at the average tax rate, but on top – that is, at the marginal tax rate. If someone with mid-range main income additionally earns CHF 12,000, they see on this CHF 12,000 a combined rate from federal, cantonal, and municipal taxes that, depending on canton and municipality, lies well above the previous average tax burden. The rule of thumb for planning: Calculate based on the marginal tax rate, not the tax amount divided by income.
Counting against this are deductible expenses. Room or daily rental, advertisements and profile fees, travel expenses, work materials, hygiene items, a portion of telephone and internet, further education, consulting costs – all of this reduces the taxable net income if documented. Without receipts, the expense does not exist for tax purposes. A simple record with date, amount, and purpose, kept from the first month, is the biggest lever in this entire text.
Special Case: Source Tax
Anyone subject to source tax – for example with residence permit B without settlement – automatically enters subsequent ordinary taxation (NOV) with an independent side business. This is conducted ex officio if, in addition to the source-taxed salary, other taxable income components exist. From earned income of CHF 120,000, NOV is mandatory anyway. For voluntary applications, the deadline is March 31 of the following year; the previous paper form is replaced by an eService solution as of January 1, 2026.
In practice, this means: The side income triggers a complete tax return – once triggered, it typically remains that way. This is not a disadvantage, but merely shifts the moment of truth. You should plan for it rather than be surprised by it.
Fixed Point 3: The Thresholds That Strike Only the Day After Tomorrow
This is the most commonly underestimated item. Individual premium reductions (IPV) are calculated based on the last legally binding tax assessment – for IPV 2026 typically on tax year 2024. Additional income earned in 2026 thus affects the entitlement only in 2028.
This time lag is insidious. It creates the impression for two years that the calculation works – and then sends the correction in a year when the additional income may have long since disappeared. If you start in 2026 and stop in 2027, you can receive a reduced premium reduction in 2028 for income that no longer exists.
In addition, a new calculation mechanism takes effect in 2026: The reference premium rises to 70 percent of the average regional premium, the basic amount accordingly falls to 30 percent. In the canton of Zurich, the employee contribution rates for 2026 are 8.4 percent of taxable income for single persons and 10.5 percent for married couples. The specific income limits vary by canton and – in Zurich – by premium region; the current values are published by the respective cantonal compensation office.
The IPV is just one of several income-dependent benefits. Daycare fees, education subsidies, alimony advances, rent contributions in individual cantons: They all tie to taxable income, and many work with steps rather than sliding curves. The real marginal rate of a second income can thereby be significantly higher than the tax rate in certain phases. If you have children in subsidized care, you should look at the fee schedules of your own municipality in advance – that is half an hour of work and can be worth four figures.
What the Main Job Has to Do With It – and What It Doesn’t
A side income is fundamentally permissible in Switzerland. The limit is the duty of loyalty under Article 321a (3) of the Swiss Code of Obligations: Forbidden is what competes with the employer or makes proper performance of the main work impossible. There is no statutory requirement to report secondary employment.
Contractually, however, more can be agreed. Reporting and approval clauses in the employment contract or staff regulations are permissible and widespread, and the contracting parties can go further – limited by the personality rights of the employee. The first concrete step is therefore always the same: read your own employment contract and the regulations before you plan anything else. For public sector positions with cantons, municipalities, or in hospitals and schools, the rules are generally stricter than in the private sector.
A second point concerns working hours. The labor law limits the maximum weekly working time to 45 hours for office and industrial staff and 50 hours for other employees, and it prescribes a daily rest period of at least eleven hours. These provisions protect employees. They do not apply to a self-employed secondary activity – which means there is no legal upper limit here, only a physical one. That is precisely where the risk of the model lies: Side income is not slowed by rules, but by exhaustion. And it comes, as experience shows, first in the main job, there where termination hurts.
An Honest Example Calculation
The following figures are an illustration with stated assumptions, not a forecast. Assume: four appointments per month at CHF 400, so CHF 1,600 gross monthly or CHF 19,200 per year.
Direct Costs per Month
- Room or hotel costs: CHF 400
- Advertisements, profile, verification: CHF 60
- Travel, materials, hygiene, phone portion: CHF 100
- Total: CHF 560
Net income: CHF 1,040 per month, CHF 12,480 per year.
Deductions on Annual Basis
- AHV/IV/EO according to declining scale including administrative costs: around CHF 700 to 750
- Income tax at the marginal tax rate, here assumed 25 percent on CHF 11,750 (net income less deductible social contributions): around CHF 2,900
Leaves around CHF 8,850 per year or just over CHF 735 per month – from CHF 1,600 gross income. About 46 percent. Any loss of premium reduction from tax year 2028 is not yet included in this.
And per hour? Realistically calculating four hours per appointment including communication, preparation, travel, and follow-up, that is 16 hours per month, 192 per year. That comes to around CHF 46 net per effectively spent hour.
The Counter-Check. A 10 percent increase in working hours at an annual salary of CHF 70,000 brings CHF 7,000 gross. After social deductions of around 13 percent and taxes at the same marginal rate, about CHF 4,400 remains – for approximately 190 additional working hours. Around CHF 23 net per hour.
The result is uncomfortable, but it is the result: Even after all deductions, the hourly return in the example remains roughly twice as high. The error almost never lies in the calculation not being worthwhile – it lies in comparing gross with net and not counting preparation time. If you calculate CHF 400 with CHF 400, you are planning with an amount that never existed.
What the calculation does not show: unpaid inquiries that lead to nothing, cancelled appointments, times without demand, and the fact that a cancellation due to illness in side income does not trigger any wage continuation claim.
The Blind Spot: Provision and Risk of Loss
Three gaps arise almost automatically:Second Pillar. The occupational pension fund (BVG) entry threshold for 2026 is CHF 22,680. Secondary employment below this limit is not mandatory insurance, and for self-employed persons there is no obligation at all. The additional income increases the AHV contribution base but not the pension fund.
Pillar 3a. Those enrolled in a pension fund through their main job may deposit a maximum of CHF 7,258 in 2026 – secondary employment does not raise this limit. Only those not affiliated with a pension fund can deposit up to 20 percent of net earned income and a maximum of CHF 36,288. The maximum amounts remain unchanged from 2025.
Accident and Illness. Non-occupational accident insurance through the primary employer only applies if the workload is sufficient and does not cover self-employed activity. Sick day benefits for secondary employment exist only if voluntarily purchased. In the event of several weeks of absence, the income component that was supposed to stabilize the budget disappears entirely.
A sobering consequence: part of the secondary income belongs in a separate account, not in the regular budget. A rule of thumb to start – set aside roughly one-third for taxes, AHV, and potential losses. Those who don’t do this finance their living expenses in the first year and their tax bill from the first year in the second.
Visibility to Authorities Is Not Visibility to Everyone
Many hesitate to register because they fear leaving a trail that might eventually reach their employer, family, or neighbors. This concern is understandable, but it conflates two different levels.
Tax data and AHV data are subject to official and tax secrecy. They are not shared with employers, landlords, or private individuals. The declaration must be truthful, but the sector description in a tax return is administrative data, not a public register. Cantonal registration and licensing requirements in the sex industry are separately regulated and vary widely – there is no uniform registration requirement across Switzerland. Some cantons require personal registration; salons, agencies, and street-based sex work each have their own licensing requirements and local restrictions. What applies at your own residence and workplace must be clarified at the cantonal level; advisory services usually know local practice better than any general overview.
The actual discretion risk lies not with authorities but in everyday life: advertisements, photos, phone numbers, payment methods, neighbors. This is a different issue than tax filing – and it requires different tools. Those who take on secondary employment out of financial necessity while simultaneously wanting to keep it completely invisible regularly underestimate how much work this second task entails in itself. How much effort this involves and what it costs psychologically, we describe in more detail in the article on the income no one is supposed to see.
What the Calculation Cannot Do
A calculation is no substitute for risk assessment. The exploratory study published by ProCoRe in 2024 surveyed 24 sex workers in Switzerland – 22 cisgender women and two trans women between 28 and 63 years old, mostly with migration backgrounds and predominantly with legal residence. 70.8 percent of respondents reported stealthing or attempted stealthing, often multiple times. The sample is small and not representative, but the direction is clear enough to include in a decision.
Those entering part-time have a structural disadvantage compared to full-time workers: less practice in assessing requests, no established network, less often a second person who knows where you are. This can be learned but not improvised. Advisory services such as Xenia in Bern, Aids-Hilfe Schweiz, and specialist services in the ProCoRe network provide free, confidential advice regardless of workload – including on safety agreements, negotiation strategies, and how to exit a situation you’ve negotiated yourself into.
The Short Checklist Before the First Franc
- Read employment contract and personnel regulations – is there a registration or approval requirement for secondary employment?
- Write down full costs, not prices: rent, advertisements, travel, materials, unpaid time.
- Determine marginal tax rate – using your home canton’s tax calculator, with and without additional income. The difference is the real burden.
- Check income-dependent benefits: cantonal IPV limits, municipal childcare fee levels, scholarships.
- Clarify AHV situation: below or above the exemption threshold of CHF 2,500, and if above – register with the cantonal equalization office.
- Keep documentation from day one: date, amount, purpose. No receipt, no deduction.
- Set aside roughly one-third separately for taxes, contributions, and losses.
- Cover loss of income risk, at least mentally: what happens with six weeks of illness?
- Clarify local registration requirements – cantonal, not national.
- Contact an advisory service before starting. It costs nothing and changes the situation more than any price list.
Conclusion
Sex work as a side job is almost always discussed morally in public debate and almost never commercially. That is a mistake, because the people who take it on decide above all one thing: whether the calculation works.
It works in many constellations – but not in the amount the hourly rate suggests. Between gross and net in 2026 lies the declining AHV scale, a marginal tax rate instead of an average rate, direct costs of often one-third of income, and threshold effects that arrive with a two-year delay. Those who calculate this beforehand make a decision. Those who calculate it afterward receive a notification.
The difference between the two is not the profession. It is the accounting.
