Everything that matters about SA incorporation for Sàrl companies in Stetten (AG)

Whether you run a Sàrl, an SA or a sole proprietorship in Stetten (AG), SA incorporation eventually lands on your desk. Here are the practical reference points — legal basis, deadlines and common pitfalls — to decide with a clear head.

Choosing the structure: Sàrl, SA or sole proprietorship

Chronologically, incorporation follows a precise thread: choose the form and the company name, pay the capital into an escrow account (Sàrl/SA), notarised deed, entry in the commercial register, then AHV affiliation and the VAT check. The Confederation's online desk (EasyGov) walks founders through these steps.

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

In Switzerland, the duty to keep accounts stems from art. 957 ff. of the Code of Obligations. Legal entities (Sàrl, SA) and sole proprietorships with at least CHF 500,000 in revenue keep full accounts: balance sheet, income statement and notes. Below that threshold, a simplified record of income, expenses and assets is sufficient.

The good news: the Swiss frame is stable and predictable. Structure SA incorporation once — chart of accounts, document flow, calendar — and the same organisation pays off for years.

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 Stetten (AG), 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.

Salaries and social contributions: the rates to know

Every salary paid in Switzerland triggers joint contributions: AHV/IV/APG at 10.6% in total, i.e. 5.3% borne by the employer and 5.3% withheld from the employee; unemployment insurance at 2.2% (1.1% each) up to CHF 148,200 of annual salary. Add occupational pension (LPP credits of 7 to 18% of the coordinated salary depending on age, employer at least 50%), accident insurance (occupational accidents paid by the employer) and family allowances.

Withholding tax applies to foreign employees without a C permit: the employer deducts tax at the cantonal rate and remits it. The annual salary certificate remains mandatory for all staff — it is the linchpin connecting payroll accounting, tax returns and AHV audits.

Stetten (AG): what changes, what does not

Sole proprietorship, Sàrl or SA in Stetten (AG): the AHV contact remains the competent compensation office, and taxes follow the scales of the canton Aargau.

Stetten (AG) requires no special bookkeeping: the Code of Obligations applies at postal code 5608 as everywhere else, and a well-kept digital file transfers smoothly to any auditor in the canton.
