Sole proprietorship common mistakes in Remigen: what every SME should know

Swiss accounting law (art. 957 ff. of the Code of Obligations) sets a precise frame, yet day-to-day practice often stays fuzzy. This guide walks through what actually matters for a business based in Remigen.

Choosing the structure: Sàrl, SA or sole proprietorship

Contributions in kind (vehicle, equipment, client portfolio) are possible when founding a Sàrl or an SA, but they follow strict valuation and disclosure rules. Cash contribution remains the simple route, in Remigen as elsewhere.

Sole proprietorship starts on day one: founding capital, notary and register fees are the first entries. Opening a separate business bank account immediately — even for a sole proprietorship — saves hours of sorting private from business.

Swiss VAT: rates, threshold and filings

Taxable consideration is not limited to the invoiced price: barter, set-offs and benefits in kind count too. The safe reflex: every economic advantage received is documented and qualified.

The right reflex for sole proprietorship: file every supplier invoice with its VAT on receipt. Forgotten input VAT is money definitively lost once the limitation period runs out.

Digitalising sole proprietorship: 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 Remigen as everywhere.

For an owner in Remigen, a dashboard only has value if the data is fresh: automating data entry means, first of all, buying up-to-date information about your own business.

The Swiss legal frame for sole proprietorship

Responsibility for the books is personal: in an SA, organising the accounting is one of the board's non-transferable duties (art. 716a CO); in a Sàrl, the managing directors carry the same duty. Outsourcing the execution never transfers that underlying responsibility, including for a company based in Remigen.

Late books show from the outside: poorly calibrated tax instalments, provisional filings, slow answers to the bank. Staying current is also a matter of image.

Remigen: what changes, what does not

Working with a fiduciary from Remigen no longer depends on geography: the documents of a business in Remigen are shared online, while the canton Aargau keeps its own deadlines for the tax return.

Federal deadlines do not move in Remigen: VAT within 60 days, salary declaration in January, 10-year record retention — postal code 5236 changes nothing about those rules, only the sender's address.

Frequently asked questions

What are the legal obligations for sole proprietorship 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 Remigen: federal law applies.

When is entry in the commercial register mandatory?

A Sàrl and an SA only come into existence with their registration. A sole proprietorship must register from CHF 100,000 of annual revenue; below that, registration stays voluntary but adds credibility and protects the business name. Registration goes through the canton's commercial register office — for Remigen too.

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 Remigen as anywhere.

Do you need a fiduciary for sole proprietorship, or can you do it yourself?

Both are defensible. Below CHF 500,000 of revenue, a sole proprietorship may keep simplified accounts itself. As soon as payroll, VAT and a closing with tax stakes are involved, professional support prevents mistakes that cost more than the fees. With a shared platform, the fiduciary does not even need to be in Remigen.
