Sàrl incorporation for physiotherapy practices in Münchwilen (AG) explained simply

Whether you run a Sàrl, an SA or a sole proprietorship in Münchwilen (AG), Sàrl 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.

From day one, three administrative tracks open: affiliation to an AHV compensation office, review of VAT liability (CHF 100,000 threshold) and setting up the accounts. Handling Sàrl incorporation from the first month costs far less than reconstructing a whole year in December.

Digitalising Sàrl incorporation: what actually works

Digitising does not mean hoarding PDFs: without the document-entry link, a digital file is as opaque as a box of archives — true in Münchwilen (AG) as everywhere.

Electronic archiving is fully recognised: Swiss bookkeeping regulation admits electronic retention of records provided integrity and readability are guaranteed for the 10 years of art. 958f CO. A paper binder is no longer an obligation — provided the archiving system is serious.

Swiss VAT: rates, threshold and filings

Charging VAT is not a matter of style: the number, the correct rate, the tax amount — the tax administration checks the form as closely as the substance, including at SMEs in Münchwilen (AG).

For an SME in Münchwilen (AG), electronic filing of VAT returns has been mandatory since 1 January 2025; the tax administration's online portal is also where extensions are requested and past periods consulted. Combined with accounts that prepare the return automatically, Sàrl incorporation stops being a quarterly chore.

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.

An employer in Münchwilen (AG) does well to fix payday on a set day of the month: funds, employees and cash flow organise around it, and Sàrl incorporation becomes routine instead of a sprint.

Münchwilen (AG): what changes, what does not

Münchwilen (AG) (postal code 4333, canton Aargau) applies the same federal rules as the rest of the country: what changes in Münchwilen (AG) are the cantonal counterparts — tax administration, compensation office, commercial register.

Federal deadlines do not move in Münchwilen (AG): VAT within 60 days, salary declaration in January, 10-year record retention — postal code 4333 changes nothing about those rules, only the sender's address.

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 Münchwilen (AG) as anywhere.

What are the current Swiss VAT rates?

Since 1 January 2024: 8.1% (standard), 2.6% (reduced — for example food and medicines) and 3.8% (accommodation). Returns must be filed and paid within 60 days after the period ends (quarterly under the effective method, semi-annually under the net tax rate method). These federal rates apply unchanged in Münchwilen (AG).

What are the legal obligations for Sàrl incorporation in Switzerland?

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 Münchwilen (AG): federal law applies.

What is simplified bookkeeping and who can use it?

Sole proprietorships and partnerships under CHF 500,000 of revenue may limit themselves to recording income, expenses and assets (art. 957 para. 2 CO). Once over the threshold — or upon founding a Sàrl or an SA — full accounts with balance sheet, income statement and notes become mandatory. The CHF 500,000 threshold is assessed the same way in Münchwilen (AG).
