At the end of a work day, a sum sits on the table. It feels like income, but it isn’t yet. Three bodies have a claim to part of it: the compensation fund, the tax administration of canton and state – and the municipality where you live. The difference between sex workers who run into a back payment in the third year and those who don’t is rarely the income itself. It’s the question of whether they’ve understood when which bill comes due.
This text describes exactly that: the timeline between AHV advance payment, tax assessment, and final contribution settlement in the canton of Neuchâtel, the figures you can expect in 2026, and the reserves that follow from it. It’s not about the question of whether you need to register, but about what happens to the money afterward.
Registration is done, the bill is not
Anyone in the canton of Neuchâtel who works in sex work registers with the ORCT (Office des relations et des conditions de travail, Control Sector, in the Service de l’emploi). This registration is a supervisory right. It tells the compensation fund nothing, it tells the tax administration nothing, and it doesn’t give you self-employed status – that’s a separate procedure at the fund, with its own documentation. Anyone unfamiliar with this distinction will find a detailed explanation of why ORCT registration and registration with the compensation fund are two different paths.
Likewise, registration says nothing about where you’re allowed to work: salons need a permit, private apartments and licensed specialized premises are possible, the street is forbidden in the canton. This too is broken down in a separate post on the Neuchâtel location question.
From here on, it’s only about the money.
The advance payment system: The fund calculates based on a figure you provide
The Caisse cantonale neuchâteloise de compensation (Faubourg de l’Hôpital 28, 2001 Neuchâtel) doesn’t send you a bill based on your actual income. It can’t – nobody knows your 2026 income before 2027. So it works with advance payments: an estimate that gets corrected later.
The first year: you estimate yourself
When registering, the fund asks about the anticipated income for the current year. You provide this figure. It’s not a formality, but the basis for all invoices in the coming months. Those who set it too low initially pay little and get a back payment later; those who set it too high give the state an interest-free advance and get it back. Both errors are correctable – but the first one only if you’re prepared for it.
The rhythm: quarterly, ten days, five percent
Advance payments are generally due quarterly, with payment typically due within ten days after the quarter ends. Those who pay late or report too low risk a default interest rate, which at the AHV traditionally sits at five percent. This is not a moral judgment on your bookkeeping, but simply the price for keeping money longer than you were entitled to.
The notification requirement that almost everyone forgets
If your income changes significantly – up or down – you must notify the fund so the advance payments can be adjusted. A decrease protects you from liquidity problems, an increase protects you from back payments. Especially in sex work, where income fluctuates greatly depending on season, health, and work location, this notification is the most important control tool you have. A phone call or brief letter usually suffices.
The final settlement doesn’t come from the fund, but from the tax office
This is the point where most surprises arise. The compensation fund doesn’t determine your contribution-liable income itself. The cantonal tax administration notifies it of the finally assessed income from self-employment; this notification binds the fund regarding the amount of income (Art. 23 AHVV). Only then does the fund make its final accounting, offsetting the paid advances and billing the difference – or issuing a refund. In doing so, the fund recalculates the personal contributions you deducted in your tax return for contribution purposes.
The timeline looks like this in practice:
- 2026 – you work and pay advance payments based on your estimate.
- Early 2027 – you file your tax return for 2026.
- 2027/2028 – the assessment becomes final, the tax administration notifies the fund of the income.
- After that – the final AHV settlement for 2026 arrives, along with any back payment.
This is why the third year is the most expensive: current advance payments, the final settlement for a previous year, and the tax bill all come together. If you earned well in the first year and less in the third, you still pay for the first – retroactively.
The figures you can expect for 2026
Contribution rates are regulated nationwide and collected at the cantonal level. For self-employed individuals in 2026:
- Maximum rate AHV/IV/EO: 10.0 % of net income, starting at an annual income of CHF 60,500.
- Degressive scale for income between CHF 10,100 and CHF 60,500; the lowest rate on the scale is 5.371 %.
- Minimum contribution CHF 530 per year for income up to CHF 10,100 – even if you made no profit. The minimum contribution is not a penalty, but secures your contribution year for your future pension.
- Administrative cost contribution on top: legally a maximum of 5 % of contributions, often significantly less depending on the fund. Your fund will tell you the effective rate.
- Family allowances: Self-employed individuals pay an additional contribution to a family compensation fund (in Neuchâtel, fund rates for 2026 are around 1.5 %). Entitlement to family allowances for self-employed individuals starts at an annual income of approximately CHF 7,560.
- Value-added tax: mandatory from CHF 100,000 worldwide turnover, calculated over twelve rolling months; you then have 30 days to register with the Federal Tax Administration. Smaller businesses can opt for the simplified net tax rate method.
For taxes, three levels come together: federal direct tax, cantonal tax, and municipal tax. The canton of Neuchâtel applies a coefficient of 124 % of simple tax for natural persons in 2025 and 2026; municipalities set their own coefficient, which varies considerably across the canton – the city of Neuchâtel is in the region of around 87 %, other municipalities considerably higher. Two people with identical income thus pay different amounts depending on their municipality of residence. Only the cantonal coefficient list published annually is binding.
What is deductible – and what your accounting must deliver for it
Taxation is based not on turnover, but on profit. Business-justified expenses reduce it: room rent in the salon, advertisements and platform costs, work materials and hygiene products, cleaning, phone and internet in business use, trips between work locations, permit and supervision fees, contributions to the compensation fund. What is also privately used can only be recorded proportionally – and what you can’t document doesn’t exist for the tax administration.
That’s why the obligation to keep records is not a sideshow:- Anyone earning less than CHF 500,000 in annual revenue may keep simplified records — income, expenses, and assets. A commercial accounting system with a balance sheet is only mandatory above that threshold.
- Documents and records must be kept for ten years.
- Your tax return must include Annex 4 for income from self-employment — one attachment per activity. Explanations are provided in Notice 3 from the Service des contributions.
In a cash business, this means: a daily journal. Date, income, expense, receipt. If you keep this daily, you have a figure at year-end that you can defend. If you don’t keep it, you negotiate with the tax administration over estimates — and estimates rarely favor taxpayers.
Deadlines are tight: The return for tax year 2025 was due in the canton of Neuchâtel on February 20, 2026; extensions are possible upon request. If you don’t file, you receive a notice with a 30-day deadline; if you don’t respond to that either, the tax office issues an assessment based on its discretion — along with a fine that can be up to CHF 1,000.
The Reserve: The Money That Isn’t Really Yours
Let’s work through a simple example with net income of CHF 70,000:
- AHV/IV/EO at 10.0%: CHF 7,000
- Administrative contribution: depending on the fund, a few dozen to a few hundred francs
- Family allowance fund at roughly 1.5%: around CHF 1,050
- Income taxes (federal, cantonal, municipal): heavily dependent on place of residence, marital status, and deductions
Social contributions alone come to over CHF 8,000 before the first tax bill arrives in your mailbox. As a rule of thumb — not a calculation, but a safety margin — many self-employed people set aside 30 to 35 percent of every payment in a separate account they don’t touch. It’s inconvenient, but it’s the only method that actually works in year three.
Part of this reserve can be parked productively: Self-employed people without a pension fund may contribute up to 20% of net self-employment income, maximum CHF 36,288 (2026) to pillar 3a, and this amount is deductible from taxable income. The money is locked in until retirement — but it reduces your tax bill in exactly the year you earned well.
What AHV Explicitly Doesn’t Cover
Self-employed status costs you more than just contributions; it also costs you protection. As a self-employed person, you are:
- not covered by unemployment insurance — ALV is not available to the self-employed;
- not automatically covered by accident insurance — you must add accident coverage to your health insurance or voluntarily enroll under the UVG;
- without income insurance for sick leave, unless you purchase it — every week without work is a week without income;
- not automatically enrolled in occupational pension provision — pillar two is voluntary for you.
What you do have: disability insurance (IV) protection, pension entitlements, and maternity benefits. These require that you be AHV-insured for nine months at the time of birth and have been employed for at least five months during that period; they amount to 80% of the relevant income, maximum CHF 220 per day, and run for 14 weeks. Self-employed people must apply themselves. This is exactly where proper registration pays off years later — if you were never registered, you have no entitlement.
Short-term Stay: Many Registrations, Few Tax Years
The canton registered 779 people between January 1 and December 31, 2025 who registered for the first time to engage in sex work in the canton. A large proportion of these are short stays. Different rules apply to this situation than to year-round activity with residence in the canton: residency status, registration procedures, and the question of whether tax liability in the canton even arises are interconnected. How much your passport determines the answer is described in detail using another canton as an example — and because these questions vary from canton to canton, it’s worth checking how to properly read cantonal regulations before relocating. Your personal situation can only be clarified definitively by the Service des contributions or the migration authority.
