Limited statutory audit for construction companies in Saxon: rules, deadlines, best practice

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

Year-end closing: how the mechanics work

The income statement reads as a cascade: gross margin, operating result, financial result, extraordinary result. Each level answers a different question — mixing levels blurs the steering.

The notes complete the figures: valuation principles, liabilities towards pension institutions, contingent liabilities, or the number of full-time positions. Careful notes reduce questions from the auditor and the banks.

A Swiss SME's accounting calendar

Three families of deadlines shape the year: federal (VAT within 60 days, salary declaration in January), cantonal (tax return, extensions depending on the canton, including in Saxon) and internal (closing, general meeting within six months). Mixing them up is the leading cause of delays.

An SME in Saxon that holds its calendar twelve months straight changes its position: fewer official reminders, easier extensions — and limited statutory audit stops being a source of worry.

Outsource limited statutory audit or keep it in-house?

A good test before choosing: ask the fiduciary HOW it wants to receive the documents. A precise answer (formats, frequency, platform) says more than any brochure — including in Saxon.

A business in Saxon can combine the models: internal day-to-day entry, monthly external supervision, closing and taxes with the specialist — limited statutory audit splits very well.

The Swiss legal frame for limited statutory audit

Whether a business sits in Saxon or elsewhere in Switzerland, the same federal law applies — one of the strengths of the Swiss system for limited statutory audit. 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 limited statutory audit, 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.

Saxon: what changes, what does not

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

Federal deadlines do not move in Saxon: VAT within 60 days, salary declaration in January, 10-year record retention — postal code 1907 changes nothing about those rules, only the sender's address.

Frequently asked questions

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

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 Saxon manages its documents, VAT and exports exactly as anywhere in Switzerland.

Can limited statutory audit be automated with AI?

Largely, yes: automatic document reading, posting suggestions, bank reconciliation via QR references and VAT exports. Human approval remains essential — AI prepares, the professional checks. That is exactly how MyFiducia.ai approaches limited statutory audit.

Do you need a fiduciary for limited statutory audit, 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 Saxon.

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 Saxon too.
