A business in Thurgau told the Federal Tax Administration it carried out around 6,200 sexual services per year. The administration calculated differently: it took the number of bottles of Champagne sold, took the number of condoms purchased – over 20,000 a year – and estimated the turnover from that. Two services per three glasses of Champagne, 80 percent half-hour appointments at 180 francs, 20 percent hour appointments at 300 francs. The Federal Court deemed the business’s figure „manifestly implausible“ and upheld the estimate. Back payment for the years 2007 to 2010: approximately 440,000 francs in VAT.
This case is usually told as a VAT story. But it is above all a lesson about receipts. The same condom invoice that proves a business expense also proves a turnover. Anyone in the erotic industry thinking about deductions inevitably also thinks about documentation – in both directions. That’s exactly what makes the subject so uncomfortable and so important.
This article clarifies what can actually be deducted from income in 2026, where practice draws the line, and why the most obvious expenses are most often denied.
The basic rule is short – and it’s not the one you’d expect
For self-employed persons, Art. 27 of the Federal Act on Direct Federal Taxation applies: deductible are business or professional expenses. No catalog, no positive list. Three questions decide:
- Material connection. Does the expense serve to generate income or maintain the business? Not: does it have anything to do with work.
- Proportionality. Is the amount in reasonable proportion to turnover? A photo shoot for 800 francs at 90,000 francs annual turnover is unremarkable. The same shoot at 12,000 francs turnover will raise questions.
- Receipt. Without proof, no deduction. This is not a formality but the rule on burden of proof: the taxpayer must document tax-reducing facts.
The key point is that the first question is not „do I need this for my work?“ but „does this belong to the business or to my personal life?“. This line fails more deductions in the erotic industry than anything else.
The line nobody likes: living expenses instead of business expenses
Swiss practice knows the concept of professional standard costs. These are expenses that, while occasioned by professional status, nonetheless belong to private living expenses – because they cannot be separated from private life.
The classic example is clothing. Deductions for work clothes are unproblematic for a lab coat, a raincoat, safety shoes, a uniform. They are, according to established practice, not possible for an expensive suit or designer clothing, even if purchased exclusively for professional reasons: it can also be worn privately, so it is a living expense. What is required is that the garment is usable exclusively for professional purposes and is worn out faster than average – both, not one or the other.
Applied to the erotic industry, this means, uncomfortably but consistently:
- Lingerie, shoes, everyday wardrobe: generally not deductible. The argument „I would never wear that privately“ is not a tax criterion.
- Specific costume and fetish material, latex, stage or role-play equipment, studio equipment: more likely to be accepted, because exclusive professional usability is more tangible. Here, photographic documentation of the equipment alongside the invoice is worthwhile.
- Cosmetics, hairdressing, nail studio, fitness membership, dental aesthetics, cosmetic procedures: practically never deductible. These are expenses that can be prerequisites for any employment and are therefore considered living expenses. That it’s market positioning changes nothing.
Anyone who takes large amounts in these categories to their tax return risks not just having them struck, but inviting closer scrutiny of the entire profit and loss statement. That’s a bad trade.
What actually works in practice
Space: the largest item by far
Anyone renting rooms or days in a salon has the cleanest deduction in the industry – provided there is something in writing. Daily rentals, weekly rates, room shares, cleaning charges, laundry shares: all business justified, all documentable. Cash payment without receipt turns an undisputed deduction into a lost one. A receipted list with date, amount, and signature of the person renting is the minimum.
Working in your own apartment is canton-dependent. What is required is a separate room used predominantly for business. The deductible share is calculated according to one of three formulas depending on the canton: rent plus ancillary costs divided by the number of rooms plus two (as with federal direct tax and in cantons like Bern, Lucerne, Aargau, Solothurn, Thurgau, Zug), divided by the number of rooms plus one (including St. Gallen, Schaffhausen, Baselland, Fribourg, Zurich for apartments), or divided by the number of rooms (Glarus, Neuchâtel, Ticino; Basel-Stadt with a reduction). For a 4-room apartment at 1,800 francs, that’s roughly 300, 360, or 450 francs per month depending on the formula – a difference that amounts to 1,800 francs in tax base over a year. It’s worth knowing your canton’s formula before estimating.
Consumables and hygiene
Condoms, lubricants, gloves, disinfectants, disposable pads, cleaning products, laundry: unquestionably deductible, usually in small amounts that add up to a serious sum over the year. And here the lesson from the Thurgau case returns: these receipts are also the most precise documentation of volume. Anyone purchasing 20,000 condoms and declaring 6,200 appointments has a problem no deduction can fix. The consequence is not to stop collecting receipts – but to keep the income side so it matches the expense side.
Advertising, platforms, visibility
Ads, profile upgrades, platform subscriptions, banner placements, photo shoots, domain and hosting, profile text translations: all classic advertising expenses. Invoices from platforms are generally clean receipts, even if digital. For photo shoots, the difference between private portraits and profile pictures is documentable – a brief note on the invoice about what the images are used for is usually sufficient.
Mobility and tours
Business trips in a private vehicle are currently set by the Federal Tax Administration at 75 centimes per kilometer (from January 1, 2026; previously 70 centimes). A logbook with date, route, and purpose is required – subsequent estimates rarely hold up. Public transport tickets, half-price passes, GA shares, flights and train journeys on tours, accommodation: deductible insofar as business related. For mixed trips, proportional allocation applies. Anyone working rotationally in several cities regularly has the second-largest cost block after room rental – and often throws it away because nobody keeps train tickets.
Equipment, furnishings, depreciation
Purchases under 1,000 francs can be fully depreciated in the year of purchase. Beyond that, they are depreciated over several years, according to the Federal Tax Administration’s standard rates – for vehicles, for example, 40 percent declining balance, for furniture and fixtures lower. Affects beds, washing machines, furniture, lighting, studio equipment, laptop, camera. For items with private co-use, a private share must be excluded; if you do this yourself and plausibly, you prevent the authority from doing it more generously.
Telephone, internet, software
A separate business mobile with its own subscription is fully deductible and is the easiest tax path – and has the added advantage of keeping business communication separate from private. For a mixed-use connection, a business share is estimated; 50 percent is defensible, 100 percent is not.
Third-party services and consulting
Accounting and bookkeeping costs, legal advice costs related to the business, translations, cleaning services, web design: business expenses. Commissions and referral fees are also expenses – but they simultaneously document how close the relationship to the agency or salon actually is. If you combine a revenue share, fixed working hours, and instructions in a single receipt, you give the compensation fund material for a completely different question; how this question is decided in the Swiss erotic industry depends on criteria that fall together with the question of status between self-employed and employed and extend far beyond the individual deduction in both tax and social insurance law.
Further education – the underestimated item
Here self-employed persons are clearly better positioned: own further education and training costs are considered business-justified expenses under Art. 27 Para. 1 DTA without limit. Employees are limited to 13,000 francs per year at the federal level. Language courses, accounting courses, massage or cosmetics training, further education for career change, professional literature, safety courses: all basically deductible insofar as there is a connection to the activity.
The deductions that aren’t business expenses – and often yield more
Besides business expenses, there are general deductions. They are most often forgotten in the industry, even though they offer the greatest leverage.
AHV/IV/EO contributions. For self-employed persons, own social insurance contributions are deductible. In 2026: at an annual income up to 10,100 francs, the minimum contribution of 530 francs; between 10,100 and 60,500 francs a declining scale with rates between 5.371 and 10.0 percent; from 60,500 francs the maximum rate. Anyone correctly registered with the compensation fund pays in reality and can deduct in reality. That contribution obligation and licensing obligation are two different things becomes particularly clear in cantons without their own sex work law, but with a contribution number.
Pillar 3a. This is the strongest legal tax lever of all. Employees with pension funds can pay a maximum of 7,258 francs in 2026. Self-employed persons without pension fund membership can pay 20 percent of net earned income, up to 36,288 francs – and deduct the entire amount from taxable income. At 70,000 francs net income, that’s up to 14,000 francs deduction in a single step, more than most business expenses combined.
The catch: this lever only works with declared income. Anyone who declares nothing saves taxes on paper while simultaneously losing 3a potential, pension building, and creditworthiness. That’s the real calculation behind cash economy.
Other: health insurance premiums (canton-limited), interest on debts, childcare, dual-income deduction, child and social deductions. And under Art. 31 DTA the loss carryforward: business losses can be offset against earnings from the following seven business years. A start-up year with equipment costs is not therefore tax-lost – but only if it was declared at all.
When withholding tax or lump sum is involved, the deductions disappear
The entire section above assumes proper assessment. A significant part of the industry is recorded differently.
Several cantons work with flat rates. Thurgau charges 400 francs per month when registering a foreign sex worker, calculated on an assumed daily turnover of 200 francs; Lucerne and Aargau have adopted the model. Elsewhere, the source tax is determined at the discretion of around 25 francs per working person and working day. The business saves itself payroll accounting, the administration saves itself the determination of actual income – and the affected person effectively loses every individual deduction. Flat rate means: your train ticket, your room rent and your pillar 3a contribution do not appear in the calculation.
There is a way back. Source tax liable persons resident in Switzerland can request a subsequent ordinary assessment (NOV) until March 31 of the following year and claim deductions therein that are not pauschal taken into account in the tariff. The distinction is important: the recalculation, also possible until the end of March, only corrects errors in gross salary, rate-determining salary or tariff application – additional deductions are excluded there. Anyone who wants deductions needs the NOV. The deadline is a time limit; it expires without anyone being reminded. How differently source tax, notification requirement and assessment interact depending on the canton is shown by the comparison with a canton in which no sex law exists, but the tax assessment still comes.
VAT: the logic changes from 100,000 francs onwards
Sexual services are normal services subject to VAT at the standard rate of 8.1 percent. A person becomes liable to pay tax if they achieve a worldwide annual turnover of 100,000 francs from services not exempted; registration must be made within 30 days of exceeding this threshold.
For the deduction question, the choice of method is decisive. With the actual method, you deduct the input tax on all purchases – room rent, materials, advertising, equipment – from the tax owed. With the balance tax rate method, you apply a sector rate semi-annually to the turnover (2026: 0.1 / 0.6 / 1.3 / 2.1 / 3.0 / 3.7 / 4.5 percent) and forgo input tax deduction entirely in return. The method is available to businesses up to 5,024,000 francs turnover and 108,000 francs tax liability. Those with high material expenses often do better effectively; those who mainly sell working time save effort with the balance rate. This is a calculation, not a matter of faith – and it pays to work it out once.
Record-keeping requirement: the minimum is smaller than many think
Self-employed persons not registered in the commercial register do not have to keep double-entry bookkeeping. What is required is a statement of income, expenses, financial position – maintained completely, chronologically and promptly. In a cash business, this means in practice a cash book with daily entries: date, amount, brief description, balance. Receipts must be kept for ten years.
The risk of gaps is called discretionary assessment. Then the authority estimates – and as the Thurgau case shows, it estimates using the data it finds: purchase invoices, room occupancy, advertising frequency, beverage orders. Against a discretionary assessment, it is not the authority that must prove its figure, but the taxpayer that must prove its obvious incorrectness. This reversal is the actual price of missing records.
A note that carries more weight in this trade than in others: record-keeping does not mean customer data. Date, amount and type of service are sufficient. Names, telephone numbers and notes about customers do not belong in the cash book – they increase risk without tax benefit.
When years are missing: voluntary disclosure without penalty
Anyone who has not declared or only partially declared up to now has an orderly way out. With the first voluntary disclosure, the tax evasion remains unpunished, provided the authority does not already know the facts and the person cooperates without reservation – the fine is waived, as is punishment for tax fraud. Back taxes plus default interest for a maximum of ten years remain. For any further voluntary disclosure, the fine is one-fifth of the evaded tax.
This is not a small step and rarely a cheap one. But it is a calculable one, and it is a prerequisite for deductions, AHV years and pillar 3a to play a role at all.
What really counts in 2026
The honest summary is unspectacular. The major deductions in the erotic industry are space, mobility, advertising, materials, further education, social insurance contributions and pillar 3a. The deductions that are talked about most – clothing, cosmetics, body work – are the ones that are most reliably cut. And the single most important factor is not knowledge of a deduction list, but the question of whether there is a piece of paper for each item.
A shoebox full of receipts and a notebook with daily income are, soberly speaking, the greatest tax saving effect in this industry – because both make the difference between an assessment based on your own figures and an estimate based on someone else’s.
Where to get support
Specialized centers provide free advice without notification to authorities. Xenia, Fachstelle Sexarbeit in Bern (Langmauerweg 1, 3011 Bern, 031 311 97 20, Mon–Fri 13:30–16:30) explicitly supports document organization, accounting, taxes and AHV. In Geneva, Aspasie provides administrative and legal support. Both are part of ProCoRe, the Swiss network for the defense of the rights of sex workers; ProCoRe can help you find organizations in other cantons. For more complex cases – voluntary disclosure, status delimitation, VAT method selection – it is worth additionally engaging a trust office, whose fees are themselves deductible.
