There is a question in the Canton of Fribourg that decides more about your annual bill than your hourly rate: Where exactly are you?
That sounds trivial, but it isn’t. Because the authorities who want a piece of your income mean something different by „where“ in each case. The cantonal police mean the canton in which you work. The compensation fund means your business location. The tax administration means your place of residence on December 31st. And the Federal Tax Administration doesn’t mean a place at all, but only a number.
People who work in sex work rarely live at a single address: a room in a salon in one municipality, an apartment in another, registration in a third canton, tours in a fourth. This distribution is precisely the reason why two women with identical income in the Canton of Fribourg receive very different bills – and why some bill arrives two years later at an address you no longer have anything to do with.
This article sorts out the places. Not the fundamentals of self-employment – those are elsewhere – but the question of which authority considers which point on the map as decisive.
Four Jurisdictions, Four Different Concepts of Location
The starting situation in the Canton of Fribourg is more straightforward than it feels once you lay it out side by side:
- Registration under the Prostitution Act: decisive is the canton in which you are active. Registration is done via the security police at Place Notre-Dame 2 in Fribourg, on Monday afternoons and Thursday mornings.
- AHV/IV/EO and family allowances: decisive is your business location, that is, the place from which you conduct your self-employed activity – not your bedroom.
- Income and wealth tax: decisive is your tax domicile, namely the one at the end of the tax period.
- VAT: not a place, but a turnover threshold – CHF 100,000 per year.
These four concepts of location coincide for a person who lives and works in Düdingen. For everyone else, they don’t. And the authorities don’t reconcile their concepts of location with each other: registering with the police creates neither an AHV file nor a tax number. You have to initiate this second registration, which no authority demands from you yourself.
AHV Follows the Business Location, Not the Bed
Responsible in the Canton of Fribourg is the Cantonal Social Insurance Institution (ECAS/KSVA) at Impasse de la Colline 1 in 1762 Givisiez, telephone 026 426 70 00, counter Monday to Friday from 08:00 to 11:30 and from 14:00 to 16:30. The website has a complete German-language section for self-employed persons – more on this below, because the language question is not a minor issue in this canton.
The jurisdiction rule is the crucial point: self-employed persons are registered with the compensation fund of the canton in which they have their business location. Not where they live. For a person who lives in Bern or Vaud and works exclusively in a Fribourg salon, this means: AHV contributions are processed through Fribourg, the tax return through the canton of residence. Two files, two correspondences, two deadline calendars – and no authority that explains this to you of its own accord.
The contribution rates for 2026 are federal and the same throughout the country:
- Minimum contribution: CHF 530 per year, without administrative costs – even with very small or negative results.
- Sliding scale: between approximately CHF 10,100 and CHF 60,500 annual income, a reduced rate applies.
- Maximum rate: from CHF 60,500 approximately 10 percent of net income for AHV, IV and EO, plus the fund’s administrative cost contribution.
With a net income of CHF 70,000, that’s approximately CHF 7,000 per year – money that nobody deducts from a payment, but that you have to set aside yourself. Whether the fund recognizes you as self-employed at all is its own separate review, which runs completely independently of the police registration; how far apart these two assessments can be is shown by looking at the status question between police and compensation fund.
Family Allowances: This Is Where the Fribourg Location Pays Off
Family allowances also depend on the canton of activity, not the canton of residence – and Fribourg pays more than the federal minimum. In 2026, CHF 265 applies for the first two children, CHF 285 from the third child onwards, plus a training allowance of CHF 60 for children in post-compulsory education, as well as a birth and adoption allowance of CHF 1,500. You are entitled to this if you are registered as a self-employed person and have AHV-subject income of at least CHF 630 per month or CHF 7,560 per year. Information is available from the cantonal family compensation fund at 026 426 75 00.
This is one of the few points where self-employment in sex work costs nothing but also brings in money. Nothing is requested automatically – the allowances only flow upon application.
Tax Follows Place of Residence – And the Coefficient Makes the Difference
Fribourg calculates income tax using a simple tax, to which the canton, municipality of residence, and – in case of church membership – the church municipality each apply their own coefficient. The municipal coefficients in 2026 range according to the canton around 60 to 130 percent; the City of Fribourg is at 80 percent, the larger municipalities in the canton mostly in the range of seventies and eighties percent. Only the list published annually by the canton is binding – the comparison portals in circulation sometimes calculate with outdated values.
What this range means in practice can be shown without tax software. Suppose the simple tax on your income is CHF 3,000:
- Municipal coefficient 70 percent → CHF 2,100 municipal tax
- Municipal coefficient 100 percent → CHF 3,000
- Municipal coefficient 130 percent → CHF 3,900
The cantonal share remains identical in all three cases, as does your income. The difference of CHF 1,800 arises solely from the question of which municipality you were registered in on December 31st. In a canton with 120 municipalities over a manageable area, that’s a location change of twenty minutes.
And this key date principle surprises many: if you change cantons or municipalities during the year, you are taxed for the entire tax period where your tax domicile is on December 31st. It is not divided monthly. A move on December 1st shifts the tax burden of the entire year.
That cantons are extremely far apart here and a low tax doesn’t automatically result in a favorable overall bill is shown by the comparison with a low-tax canton: In Zug the tax is small, but AHV is not – social insurance contributions are federal and cannot be reduced by any change of residence.
Deadlines, Forms, and Who Gets to See Your Information
Responsible is the Cantonal Tax Administration (Service cantonal des contributions, SCC). The 2025 tax return had to be filed by March 31, 2026. A deadline extension is uncomplicated: CHF 20, paid via the QR invoice enclosed with the return, without justification and without written confirmation. A further extension costs another CHF 20 or requires a justified request. It is filled out online via FriTax at fr.ch/fritax.
One point that often brings relief in counseling meetings: you do not file your tax return with your municipality. Assessment is done centrally by the cantonal tax administration; the municipality receives its share from the same assessment. Your information does not land on the desk of the municipal clerk who knows you by sight. Tax administration and compensation fund employees are also subject to official or tax secrecy.
What does flow, however, is the data stream between tax administration and compensation fund – with considerable delay. How the bill that arrives two years later emerges from this is the most common reason why suddenly a four-figure back payment appears in the mailbox of otherwise properly working self-employed persons.
Weekly Stay, Tours, and the Question of Center of Life Interests
Many sex workers in Fribourg do not live where they work. They rent a room in a salon on a weekly basis, go home on weekends, are in Bulle two weeks later, and in Neuchâtel three weeks later.
For tax purposes, in such constellations, it is not where you sleep that counts, but where your center of life interests is: where your family is, where your personal relationships are, where you regularly return. A room rented on a weekly basis in a salon generally does not establish a tax domicile. A room in which you have lived for two years, have your family doctor nearby, and receive mail, very well might – even if you have never registered with the residents’ registration office.
This becomes tricky when two cantons claim the same center of life interests for themselves. In this case, it is not your feeling that decides, but a demarcation between the two tax administrations – and until that is established, both sides can make provisional assessments. If you regularly work in several cantons, it is wise to know the registration requirements of the individual cantons in advance; the overview of the legal situation by canton is the fastest introduction to this.
For AHV, the counterpart applies: even if you work in five cantons, you have one responsible compensation fund – the one at your business location. You register your entire self-employed income there, not just the Fribourg share.
Foreign Sex Workers: Source Tax Is Usually the Wrong Term Here
This is where the most persistent misinformation circulates – even among salon operators.
Source tax covers dependent employment income: the employer deducts it from the salary and remits it. If you are self-employed, you have no employer who could settle it. Self-employed income is therefore ordinarily assessed – via the normal tax return, even with a foreign passport and even with a B permit. If you have a B permit and are simultaneously employed and self-employed, you pay source tax on the salary portion and must additionally file a tax return for the self-employed portion.
Concretely, this means: the statement „The tax is already deducted for me“ is usually not true for self-employed sex work. Nothing is deducted. The bill comes later and in full.For short stays in the registration procedure for EU/EFTA nationals without Swiss residence, tax liability depends on whether there is an economic connection in Switzerland – this is a case-by-case question answered by the cantonal tax authority, not by the police and not by the salon. In social insurance law, the opposite principle applies: earning income in Switzerland is subject to contributions here; anyone who wants to remain self-insured in their country of residence needs an A1 certificate from their home country for this. Without this document, the compensation fund assumes Swiss contribution liability.
The fourth address knows no municipality: VAT
VAT doesn’t care about your place of residence or your place of business, only about turnover. Once CHF 100,000 of taxable domestic turnover per year is reached, tax liability arises – regardless of whether there’s any profit left at the end. Turnover is what matters, not income: if you bear salon rent, advertising, and travel costs of CHF 40,000, you can easily exceed the threshold with CHF 55,000 in profit.
Registration is done with the Federal Tax Administration. Anyone who registers too late is liable retroactively from the moment the obligation arose – including default interest, while of course the customers from back then cannot be billed again. For activities with little input tax, the net tax rate method offers a much leaner administrative settlement; which rate applies to your sector is determined by the ESTV and should be clarified before registration.
Bilingual does not automatically mean bilingual service
Fribourg has two official languages – German and French, anchored in the cantonal constitution of 2004, implemented according to the territoriality principle. The Sense district is German-speaking, the See district is bilingual, the remaining districts are French-speaking; the official language of the municipality depends on this classification. A preliminary draft for a separate language law was in the consultation phase in 2025.
In practice, this means: cantonal offices like the social insurance institution and the tax authority serve you in both languages and provide their information sheets bilingually. The municipality may handle this differently. And for registration under the prostitution law, the cantonal commission has published an FAQ available in German, French, English, Spanish, and Romanian – an indication of which languages are actually spoken in the Fribourg scene. If you don’t understand the forms, don’t guess – get help.
Provision: the deduction almost nobody uses
One last point that directly relates to place of residence because it reduces your tax bill: self-employed workers without a pension fund may contribute up to 20 percent of their earned income to pillar 3a in 2026, but no more than CHF 36,288. With net income of CHF 60,000, that’s up to CHF 12,000 that can be deducted from taxable income. Those affiliated with a pension fund can contribute CHF 7,258.
In a sector without a second pillar, without employer contributions, and without wage continuation, this is one of the few levers that simultaneously save taxes and build retirement capital. What self-employment doesn’t provide, however, is coverage in case of illness – the blind spot that the article on non-insured risks of self-employment covers in detail.

How inspection density looks after registration and what role criminal police, salon inspection, and the ethics charter play is described in a separate article. On the relative scale: the cantonal police speak of around 250 officially registered sex workers; at the end of 2018, the canton had 31 salons, two-thirds of them in the city of Fribourg.
What you can clarify this week
Three questions that are quickly answered and determine the order of your next steps:
- Where is my place of business? If you conduct your work from a Fribourg address, your AHV file belongs in Givisiez – even if you live elsewhere.
- Where was I registered on December 31st? This municipality determines your tax bill for the entire year. You can find the coefficient on the canton’s annual list.
- What was my turnover, not my profit? Above CHF 100,000 in taxable turnover, there’s no way around the VAT question.
The responsible authorities have the final say on all three points: the Cantonal Social Insurance Institution for contributions, the Cantonal Tax Administration for domicile and assessment, the Federal Tax Administration for VAT. Figures, rates, and coefficients change annually – this text reflects the 2026 status and does not replace individual consultation.
These places cannot be merged. But you can know them before the mail arrives.
