Limited statutory audit for engineering firms in Losone: the practical guide

Between VAT, social contributions and the year-end close, a Swiss SME juggles dozens of deadlines a year. This page focuses on limited statutory audit in Losone: what the law requires, what can be automated, and when to delegate.

Year-end closing: how the mechanics work

The CO's accounting principles frame the closing: regularity, prudence and consistency of presentation (art. 958c CO), on the going-concern assumption (art. 958a CO). In practice, that means valuation methods kept constant from one year to the next — and documented whenever they change.

For limited statutory audit, the golden rule is to discover nothing in January: every uncertainty (doubtful receivable, dispute, unsellable stock) must be identified before the closing date, not after.

The Swiss legal frame for limited statutory audit

AHV audits and VAT audits follow the same logic: start from the documents, trace to the entries, check consistency. A business in Losone with a clean audit trail sails through these exercises.

One simple principle drives limited statutory audit: every franc in or out must be explainable by a document, an entry and an account. All of Swiss accounting law fits inside that traceability requirement.

A well-structured SME chart of accounts

Concretely, limited statutory audit benefits from three tiers: balance-sheet accounts (classes 1-2) kept spotless for the closing, income accounts (classes 3-6) shaped for steering, and closing accounts (class 9) reserved for year-end entries. Each tier has its rhythm and its owner.

In an SME in Losone, the chart of accounts is also a delegation tool: clear posting rules let a non-accountant prepare most entries without error.

Tax instalments are steered: too low, they set up a salty final bill; too high, they tie up cash. Adjusting them on current figures is a profitable reflex, in Losone as anywhere.

Handing deadline monitoring to a tool is no luxury: automatic reminders, a status per obligation, and an “all green” view that clears the mind. What matters is not who ticks the box — but that the box exists and everyone can see it.

Losone: what changes, what does not

Losone (postal code 6616, canton Ticino) applies the same federal rules as the rest of the country: what changes in Losone are the cantonal counterparts — tax administration, compensation office, commercial register.

Losone requires no special bookkeeping: the Code of Obligations applies at postal code 6616 as everywhere else, and a well-kept digital file transfers smoothly to any auditor in the canton.

Frequently asked questions

Does MyFiducia.ai work for a business based in Losone?

Yes: the platform runs online, the rules applied are federal (VAT, CO, AHV), and the file can be shared with any fiduciary. A business in Losone manages its documents, VAT and exports exactly as anywhere in Switzerland.

What are the legal obligations for limited statutory audit 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 Losone: 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 Losone too.

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 Losone: the CO dictates it, not the commune.
