Sàrl incorporation with AI in Unterlunkhofen: the practical guide
Sàrl incorporation with AI in Unterlunkhofen 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
The choice of legal form turns on three axes: liability (limited to capital for Sàrl and SA, unlimited for the sole trader), taxation (economic double taxation of company profit and dividends versus direct income taxation) and pensions (the employee of their own Sàrl is subject to mandatory LPP; the self-employed insure voluntarily).
Incorporating in Unterlunkhofen opens the same toolbox: banks, funds, fiduciaries and online tools work everywhere — the choice of seat is strategic, not technical, for Sàrl incorporation.
The Swiss legal frame for Sàrl incorporation
Whether a business sits in Unterlunkhofen or elsewhere in Switzerland, the same federal law applies — one of the strengths of the Swiss system for Sàrl incorporation. Cantonal differences concentrate on taxation (rates, filing deadlines); bookkeeping itself follows art. 957 ff. CO everywhere.
Art. 957a CO requires complete, truthful and systematic recording of transactions, each entry backed by a supporting document. For Sàrl incorporation, that means in practice: no movement without a receipt, and an audit trail that can be reconstructed at any time — including during a VAT or AHV inspection.
Swiss VAT: rates, threshold and filings
A VAT return is prepared, not endured: clean VAT accounts, one code per rate and a monthly variance check make the deadline trivial — for registered businesses in Unterlunkhofen too.
For businesses in Unterlunkhofen, VAT is in practice the most audited tax: punctual returns consistent with the books markedly reduce the odds of a deep audit of Sàrl incorporation.

Salaries and social contributions: the rates to know
Hiring the first employee triggers everything at once: affiliation to AHV and LPP funds, accident insurance, family allowances, working-time rules. A complete payroll file from day one avoids catch-ups.
For Sàrl incorporation, the winning mechanics are simple: one single payroll database (salaries, rates, allowances), monthly slips generated from it, and an annual declaration that is little more than a sum. Painful catch-up invoices almost always stem from scattered data.
Unterlunkhofen: what changes, what does not
Unterlunkhofen (postal code 8918, canton Aargau) applies the same federal rules as the rest of the country: what changes in Unterlunkhofen are the cantonal counterparts — tax administration, compensation office, commercial register.
Unterlunkhofen requires no special bookkeeping: the Code of Obligations applies at postal code 8918 as everywhere else, and a well-kept digital file transfers smoothly to any auditor in the canton.

The foundation is the Code of Obligations: proper bookkeeping (art. 957a CO), annual accounts (balance sheet, income statement, notes) and 10-year retention of books and records (art. 958f CO). VAT applies from CHF 100,000 of turnover, and social insurance settlements from the first employee. Nothing is different in Unterlunkhofen: federal law applies.
