Independent Therapist in Switzerland: Your Tax Checklist Before March 31
Documents to gather, deductible expenses, pillar 3a, cantonal deadlines — the complete guide to approach tax season serenely, whether you manage alone or with a fiduciary.
March is here. And with it, the date that every independent therapist dreads: March 31st, the deadline for filing tax returns in Geneva and Valais — with similar deadlines in Vaud and other French-speaking cantons.
Unlike employees whose salary certificate is sufficient, you must justify your income, list all your professional expenses and calculate your net profit. With proper organization, this can be done in a few hours.
How is your tax calculated as an independent?
In Switzerland, an independent therapist (sole proprietorship) is taxed on their net profit — that is, their income minus all justified professional expenses. It is also on this net profit that your AVS contributions are calculated, not on your gross turnover.
It is on CHF 56,500 — and not your CHF 80,000 turnover — that your tax rate and AVS contributions apply. Since Swiss tax is progressive, each deduction also reduces your rate. Every franc counts double.
Documents to gather
Before starting your declaration, here are the essential documents:
- Summary of all invoices issued in 2024Your total turnover — available in 1 click from your practice software (DiagNotes, OneDoc, TERAP…) or from YESbusiness.
- AVS CertificateAmount of contributions paid in 2024, provided by your compensation fund.
- Pillar 3a CertificateAmount paid during the year, provided by your bank or insurance.
- Bank statementsAll your professional accounts — automatically synchronized if you use YESbusiness.
- Professional expense receiptsRent, software, training, equipment, insurance.
- LPP CertificateIf you are affiliated with a pension fund (especially therapists with mixed activity).
- Continuing education invoices from 2024Programs, certificates, receipts — must be kept.
Thanks to direct banking connection (Swiss Open Banking), all your transactions are automatically imported and matched with your invoices. Your annual summary is available in real time — ready to send to your fiduciary.
Your invoices at tariff 590 are automatically archived throughout sessions. Each invoice is dated, centralized and accessible with one click — no more risk of forgetting a service at year-end.

This is where most therapists leave money on the table. As an independent, you can deduct all expenses justified by your professional activity.
🏠 Rent and workspace
Renting an office or consultation room is fully deductible. If you work partially from home, the proportional share of rent for the dedicated space is deductible — as well as electricity and internet at the same rate.
🩺 Equipment specific to your practice
Examination table, cushions, protective paper rolls, oils, needles, homeopathic supplies — all equipment used in your practice is deductible. For major purchases (office furniture), depreciation over several years is often recommended.
💻 Software and professional subscriptions
Software licenses used in your activity are fully deductible: DiagNotes, OneDoc, TERAP, OptaMed, Agenda.ch, YESbusiness, videoconferencing tools, etc. Keep your subscription invoices.
🎓 Training and professional development
Unlike employees (capped at CHF 12,500/year), independents can deduct their professional training expenses without limit. Seminars, conferences, specialized books, subscriptions — everything directly related to your activity is allowed.
🛡 Professional insurance
Professional liability, loss of income insurance in case of illness or accident, cyber-risk insurance — fully deductible. Not to be confused with LaMal and household liability, which are not professional expenses.
🚗 Professional travel
Public transport and vehicle costs for home visits, off-site training, parking fees related to activity. Keep a logbook for personal vehicle trips.
| Expense | Deductibility |
|---|---|
| Office rent | 100% |
| Home office share | Pro rata area |
| Professional software (DiagNotes, YESbusiness…) | 100% |
| Continuing education (independent) | 100% — no limit |
| Therapy equipment | 100% |
| Professional liability / Loss of income | 100% |
| Professional travel | Professional pro rata |
| Pillar 3a (without 2nd pillar) | Up to CHF 36,288 |
| Health insurance LaMal | Not deductible |
Pillar 3a: your most powerful tax lever
Pillar 3a is not just retirement savings. It's an immediate tax reduction tool. In Switzerland, tax is progressive: reducing your declared income also reduces your rate, not just the base. This is the double effect of 3a.
On a net income of CHF 56,500, a maximum 3a payment brings the taxable base down to CHF 20,212. In the canton of Vaud, the estimated tax savings is CHF 6,000 to CHF 9,000 depending on the municipality.
⚖️ Common case: mixed activity employee + independent therapist
Many practitioners combine partial salaried employment (institution, clinic) and independent practice in an office. The rules are different:
- Your affiliation to the 2nd pillar via your employer limits your 3a deduction to CHF 7,258 on all your income (employee + independent).
- However, LPP buybacks (2nd pillar) are fully deductible — often the most powerful lever. To be studied with your fiduciary.
- If your employee rate is low, voluntary affiliation to the 2nd pillar for independent activity can open significant additional deductions.
- The 3a payment and LPP buybacks must be made before December 31 of the relevant tax year.
If you are partially employed, check with your fiduciary if an LPP buyback is possible before year-end. This point is often more impactful than 3a alone — and widely underused.
The most common mistakes
Here are the oversights and confusions that most often occur among independent therapists:
- Forgetting to deduct software subscriptions — DiagNotes, OneDoc, YESbusiness, video tools — yet 100% deductible.
- Confusing turnover and net taxable income — and consequently overestimating tax burden.
- Not keeping receipts for continuing education: programs, certificates, invoices.
- Neglecting pillar 3a when it represents savings of several thousand francs.
- Forgetting to deduct the home rent share if you work there partially.
- Waiting until March 29-30 to gather documents — source of stress and costly errors.
- Not requesting an extension if you're not ready — simple, often free, avoids penalties.
Not ready? Request an extension
The vast majority of French-speaking cantons grant extensions, often free for a first request. The process is done in a few clicks via your online cantonal tax space.
| Canton | Initial deadline (2024 income) | Extension possible |
|---|---|---|
| GenevaMarch 31 | March 31, 2026 | Online, paid beyond a certain date |
| VaudMarch 31 | March 15, 2026 | Tolerance June 30, extension until Sept. |
| ValaisMarch 31 | March 31, 2026 | July 31 (1st), August 31 (2nd extension) |
| ValaisMarch 31 | Check cantonal tax office | Request to the Tax Service |
| Neuchâtel | Check cantonal tax office | Via the online cantonal counter |
| ValaisMarch 31 | Check cantonal tax office | Via the online cantonal counter |
In summary: 3 things to do this week
- Gather your receipts — invoices issued, expenses, AVS certificates and pillar 3a. With YESbusiness and your practice software, the essentials are already centralized.
- Check your pillar 3a for 2025 — if you don't have a 3a account yet, this is the ideal time to plan your payment before next December 31.
- If you're not ready for March 31 — request an extension now via your cantonal tax space.
Frequently asked questions
How should an independent therapist keep their accounting in Switzerland?
As a sole proprietorship, your accounting is based on a simple principle: income (invoices collected) minus deductible expenses = net taxable profit. It is on this amount — and not your gross turnover — that you are taxed and your AVS contributions are calculated. YESbusiness automates this accounting by connecting your practice software and your bank: everything is centralized, nothing is entered manually.
Does YESbusiness connect to DiagNotes, OneDoc or TERAP?
Yes. YESbusiness is designed to connect to the main practice management software used by Swiss therapists — DiagNotes, OneDoc, TERAP, OptaMed, Agenda.ch and others. Your issued invoices are automatically imported into YESbusiness, without double entry.
Do I need to register for VAT as an independent therapist?
Below CHF 100,000 in annual turnover, you are in principle exempt from VAT. YESbusiness monitors your turnover in real time and automatically alerts you if you approach the threshold — avoiding late registration and resulting penalties.
How does accounting work if I am both an employee and an independent therapist?
You have two sources of income declared separately: your salary (via salary certificate) and your independent activity profit. YESbusiness only manages the independent part. These two amounts are then added together in your personal tax return. Note: your pillar 3a ceiling is limited to CHF 7,258 if you are already affiliated with the 2nd pillar via your employer.
Can I use YESbusiness without a fiduciary?
Absolutely. YESbusiness is designed so that non-accountants can manage their accounting autonomously. Categorizations are automatic, dashboards are clear. If you work with a fiduciary, YESbusiness generates clean exports that facilitate their work — and reduce the time they bill you.
