SA incorporation for Sàrl companies in Vaux-sur-Morges: what every SME should know
Delegate, digitalise or do it all yourself? Around SA incorporation in Vaux-sur-Morges, every SME draws its own line. The reference points below — federal law, cantonal practice and lessons from the field — help you place the cursor well.
Choosing the structure: Sàrl, SA or sole proprietorship
Check the company name before any enthusiasm: availability in the commercial register, internet domain, possible trademark. Renaming later costs time and trust, in Vaux-sur-Morges as elsewhere.
First accounting reflex for SA incorporation: open the document numbering with the very first expense, even before registration. Founding costs are deductible — if documented.
The Swiss legal frame for SA incorporation
Swiss accounting law has been unified in the Code of Obligations since 2013: the same bookkeeping rules (art. 957a CO) and retention rules (art. 958f CO — 10 years for books, vouchers and reports) apply regardless of legal form. SA incorporation sits squarely within this frame, including for companies based in Vaux-sur-Morges.
For SA incorporation, the classic early mistake remains mixing private and business: a dedicated bank account and documented private withdrawals eliminate half the discussions with the tax office.
Swiss VAT: rates, threshold and filings
Three rates coexist in Switzerland: 8.1% for most supplies, 2.6% for everyday essentials and 3.8% for accommodation. Businesses staying under CHF 100,000 a year are exempt from registration but may opt in voluntarily — useful to reclaim input VAT on investments.
For businesses in Vaux-sur-Morges, VAT is in practice the most audited tax: punctual returns consistent with the books markedly reduce the odds of a deep audit of SA incorporation.

Digitalising SA incorporation: what actually works
Artificial intelligence has changed the economics of SA incorporation: automatic invoice reading reaches recognition rates that make manual entry marginal, and posting suggestions learn from corrections. The accountant does not disappear — the job shifts from data entry to control and advice.
For an SME in Vaux-sur-Morges, the real gain of digitalised SA incorporation shows day to day: no paper pile at month-end, VAT prepared continuously, and an owner reading today's figures rather than last quarter's.
Vaux-sur-Morges: what changes, what does not
Sole proprietorship, Sàrl or SA in Vaux-sur-Morges: the AHV contact remains the competent compensation office, and taxes follow the scales of the canton Vaud.
Vaux-sur-Morges requires no special bookkeeping: the Code of Obligations applies at postal code 1126 as everywhere else, and a well-kept digital file transfers smoothly to any auditor in the canton.
Frequently asked questions
What is the difference between a limited and an ordinary audit?
The ordinary audit applies to companies exceeding, for two consecutive years, two of three thresholds: CHF 20 million balance sheet total, CHF 40 million revenue, 250 full-time positions. Others fall under the limited audit, and those with no more than ten full-time positions on annual average can opt out with all shareholders' consent. These federal thresholds do not depend on the registered seat — in Vaux-sur-Morges as anywhere.
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 Vaux-sur-Morges, 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 Vaux-sur-Morges: the CO dictates it, not the commune.
Effective VAT method or net tax rate: how to choose?
The effective method deducts actual input VAT and files quarterly; the net tax rate method applies a flat industry rate to turnover, semi-annually, with no separate input VAT deduction. The flat rate suits low-cost structures; as investments grow, the effective method usually wins again. The choice rests on the company's own figures, in Vaux-sur-Morges as anywhere.
