Limited statutory audit for SA companies in Metzerlen-Mariastein: rules, deadlines, best practice
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 Metzerlen-Mariastein.
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.
A company in Metzerlen-Mariastein that presents clean, punctual annual accounts gains credibility — with its bank, its suppliers and the tax administration.
The Swiss legal frame for limited statutory audit
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 Metzerlen-Mariastein.
For limited statutory audit, the classic early mistake remains mixing private and business: a dedicated bank account and documented private withdrawals eliminate half the discussions with the tax office.
A well-structured SME chart of accounts
The same chart serves three readings: accounting (accuracy), tax (accepted adjustments) and management (margins by activity). Modern software produces all three views without double entry.
In an SME in Metzerlen-Mariastein, the chart of accounts is also a delegation tool: clear posting rules let a non-accountant prepare most entries without error.
A Swiss SME's accounting calendar
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 Metzerlen-Mariastein as anywhere.
The useful reflex: date every obligation the moment it arises. An employee hired means AHV/LPP deadlines created; VAT registration means a filing cycle set; a closing date fixed means backward planning of the close. Well organised, the limited statutory audit calendar fills itself.
Metzerlen-Mariastein: what changes, what does not
Working with a fiduciary from Metzerlen-Mariastein no longer depends on geography: the documents of a business in Metzerlen-Mariastein are shared online, while the canton Solothurn keeps its own deadlines for the tax return.
Federal deadlines do not move in Metzerlen-Mariastein: VAT within 60 days, salary declaration in January, 10-year record retention — postal code 4115 changes nothing about those rules, only the sender's address.
Frequently asked questions
How much does limited statutory audit cost in Metzerlen-Mariastein?
It depends on document volume, the number of salaries and VAT complexity — no serious figure can be quoted without examining the file. Two levers cut the bill everywhere: digitised, well-filed receipts and software that prepares entries instead of having them re-keyed.
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 Metzerlen-Mariastein 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 Metzerlen-Mariastein: the CO dictates it, not the commune.
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 Metzerlen-Mariastein.
