Everything that matters about SA incorporation for law firms in Presinge
SA incorporation for law firms in Presinge rests on three pillars: federal law that applies across Switzerland, cantonal deadlines worth knowing, and tools that eliminate re-keying. This guide puts it all in order, fact by fact.
Choosing the structure: Sàrl, SA or sole proprietorship
Partners from day one? A shareholders' agreement settles what the articles do not: exit, deadlock, valuation. Signing it while everything is fine costs an evening; negotiating it in a crisis costs the company.
Incorporating in Presinge opens the same toolbox: banks, funds, fiduciaries and online tools work everywhere — the choice of seat is strategic, not technical, for SA incorporation.
The Swiss legal frame for SA incorporation
Three documents summarise the health of a Swiss business: the balance sheet (what it owns), the income statement (what it earns) and the notes (what else you should know). All the work of SA incorporation converges on those three pages, in Presinge too.
Also worth knowing: accounts may be drawn up in the currency most relevant to the business; if that is not the franc, values must additionally be stated in CHF (art. 958d para. 3 CO). Internationally active companies gain books that match their economic reality.
Salaries and social contributions: the rates to know
Family allowances are financed by the employer through a cantonal compensation fund — rates and amounts vary from canton to canton, including in Presinge. They come on top of the federal social insurances and appear on every payslip.
An employer in Presinge does well to fix payday on a set day of the month: funds, employees and cash flow organise around it, and SA incorporation becomes routine instead of a sprint.

Digitalising SA incorporation: what actually works
Automation is judged on the exceptions: what happens when the document is unreadable, the supplier unknown, the amount divergent? A good tool isolates those cases and lets a human decide fast — precious for teams in Presinge.
For SA incorporation, migrating history must not block the start: begin on day one of the current financial year and import the history later if needed.
Presinge: what changes, what does not
Sole proprietorship, Sàrl or SA in Presinge: the AHV contact remains the competent compensation office, and taxes follow the scales of the canton Geneva.
Federal deadlines do not move in Presinge: VAT within 60 days, salary declaration in January, 10-year record retention — postal code 1243 changes nothing about those rules, only the sender's address.
Frequently asked questions
Which social contributions does a Swiss employer pay?
AHV/IV/APG: 5.3% employer share (the same is withheld from the employee); unemployment insurance: 1.1% each up to CHF 148,200 a year; occupational pension (LPP) by age and plan (employer at least 50%); occupational accident insurance paid by the employer; family allowances by canton. For an employer in Presinge, family allowances follow the canton's rates.
Which documents should be prepared for the year-end closing?
Bank and cash statements at the closing date, the inventory of stock and work in progress, final AHV/LPP/accident settlements, contracts signed or amended during the year, invoices straddling two years and the detail of accruals. With an up-to-date document archive, most of it is already there. The list is identical in Presinge: the CO dictates it, not the commune.

Yes: the platform runs online, the rules applied are federal (VAT, CO, AHV), and the file can be shared with any fiduciary. A business in Presinge manages its documents, VAT and exports exactly as anywhere in Switzerland.
How much does SA incorporation cost in Presinge?
It depends on document volume, the number of salaries and VAT complexity — no serious figure can be quoted without examining the file. Two levers cut the bill everywhere: digitised, well-filed receipts and software that prepares entries instead of having them re-keyed.
