The trade-off that costs the most when it's settled at random
Inside a Sàrl, the doctor-partner wears two hats at once. As managing director (gérant), they can draw a salary. As the holder of the shares, they can distribute a dividend. Most self-employed people arbitrate between the two using a simple logic: dividends avoid social charges, so maximise the dividend. For a doctor, that shortcut is often a costly mistake. Three sector-specific realities distort the calculation and deserve to be settled before you fix your remuneration, not after your first year-end close.
The core principle, in one sentence
In other words: salary is socially charged but "clean" from a tax standpoint; the dividend is socially light but carries an economic double taxation. The optimal arbitrage is never "all of one" or "all of the other." It's a blend, and the right blend depends on parameters that doctors, in particular, tend to underestimate.
The "all dividend" reflex runs straight into the AVS
This is general information, not individual tax advice. Thresholds and practice vary by canton, by compensation fund and by your situation; we recommend having your specific case modelled.
Pension provision changes the whole calculation and it's where doctors lose the most
- LPP buy-ins (rachats) deductible from taxable income, often the single best tax-reduction tool available to a well-paid self-employed professional;
- Supplementary (over-obligatory) pension plans covering the higher salary band
- Retirement-savings capacity that a purely wealth-based dividend never builds.
Compressing your salary to maximise the dividend therefore means, very concretely, depriving yourself of the best tax-optimisation mechanism at your disposal. Over a medical career, the cumulative gap runs into tens, sometimes hundreds of thousands of francs. This is why a "generous" salary is often more efficient than a maximised dividend: the opposite of the starting intuition.
Partial taxation doesn't erase the double taxation
The franc distributed as a dividend was first taxed at company level (profit tax), then taxed again in your hands, even if only partly. The right comparison does not pit "social charges" against "partial taxation"; it pits the total cost of the salary route (social charges + income tax, but with a deduction in the company and pension being built) against the total cost of the dividend route (profit tax + partial tax on the distribution, with no pension). Depending on income level, canton and the room left for pension provision, the outcome tips one way or the other. It's a calculation, not a rule of thumb.
The spouse and time-smoothing: two often-forgotten levers
- A spouse who works at the practice(reception, administration, billing) can be employed at a level justified by their actual activity. This spreads household income, funds their own pension and can soften the progressivity of income tax, provided the salary matches a real contribution.
- Smoothing over time: A Sàrl does not oblige you to distribute everything every year. Retaining profit in reserve and distributing when it's tax-efficient (lower-income years, financing a project, preparing a handover) avoids tax spikes and gives you flexibility a sole proprietorship simply can't offer.
So how should you pay yourself?
- Set a market-conforming salary first → it's the foundation that secures the whole structure against the AVS, before dividends even enter the conversation.
- Fill up pension provision before optimising the dividend → LPP buy-ins and supplementary plans generally come before any distribution, especially for a well-paid specialist.
- Treat the dividend as the complement, not the starting point → it makes sense on the portion that genuinely remunerates capital and entrepreneurial risk, once salary and pension are calibrated.
- Bring in the spouse and multi-year smoothing → two simple levers, often left aside, that make a real difference over time.
There is no universal split between salary and dividend. There is a split that's right for your income level, your canton and your pension goals and it rests on a quantified model, not on the rule of thumb that "the dividend costs less."
