Balance sheet preparation with AI in Fiesch: rules, deadlines, best practice
Balance sheet preparation with AI in Fiesch raises the same questions for most Swiss SME owners: which obligations apply, which deadlines are running, which documents to prepare. This page covers the federal rules in force — without unnecessary jargon.
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.
For balance sheet preparation, a closing checklist reused every year transforms the exercise: same steps, same checks, same documents — only the year changes.
A Swiss SME's accounting calendar
Extensions exist and can be requested: cantonal deadlines for the tax return, deferral of the VAT filing on a reasoned request. But an extension does not stop interest: on VAT, default interest runs from the ordinary due date even when more time has been granted.
For balance sheet preparation, two dates lock themselves in every year: the January salary declaration and the general meeting within six months — everything else is planned around them.
The Swiss legal frame for balance sheet preparation
AHV audits and VAT audits follow the same logic: start from the documents, trace to the entries, check consistency. A business in Fiesch with a clean audit trail sails through these exercises.
The good news: the Swiss frame is stable and predictable. Structure balance sheet preparation once — chart of accounts, document flow, calendar — and the same organisation pays off for years.

A well-structured SME chart of accounts
The test of a good chart of accounts is a single question: can the owner find the margins in three clicks? If not, the chart serves the tax office but not the business — even in Fiesch.
For balance sheet preparation, a few well-chosen analytical accounts (by activity, by site) beat a forest of sub-accounts nobody ever reads.
Fiesch: what changes, what does not
Working with a fiduciary from Fiesch no longer depends on geography: the documents of a business in Fiesch are shared online, while the canton Valais keeps its own deadlines for the tax return.
Fiesch requires no special bookkeeping: the Code of Obligations applies at postal code 3984 as everywhere else, and a well-kept digital file transfers smoothly to any auditor in the canton.
Frequently asked questions
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 Fiesch too.
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 Fiesch.
How long must records related to balance sheet preparation be kept?
Ten years from the end of the financial year concerned (art. 958f CO). Electronic retention is permitted if the integrity and readability of the records are guaranteed — a serious digital archive validly replaces paper binders. A business in Fiesch can therefore archive fully digitally.
