Balance sheet preparation required documents in Onnens (VD) explained simply
Balance sheet preparation required documents in Onnens (VD) rests on three pillars: federal law that applies across Switzerland, cantonal deadlines worth knowing, and tools that eliminate re-keying. This guide puts it all in order, fact by fact.
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 well-ordered closing file speeds everything up: bank statements at the closing date, a signed inventory, final AHV/LPP/accident settlements, new or amended contracts, and support for the accruals. Balance sheet preparation in Onnens (VD) then finishes in days, not weeks.
The Swiss legal frame for balance sheet preparation
A small business does not mean small obligations: from the first salary or the first VAT return, mistakes get expensive — in Onnens (VD) as anywhere.
One simple principle drives balance sheet preparation: 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
A chart of accounts gets documented: one description line per account (what, when, VAT) is enough for two people to post the same way. It is the quality manual of balance sheet preparation, valid in Onnens (VD) as anywhere.
For a business in Onnens (VD), comparability over time beats sophistication: a chart stable for five years beats a “perfect” one rebuilt every year. Banks and the tax administration read year-on-year movements first.

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 Onnens (VD)) and internal (closing, general meeting within six months). Mixing them up is the leading cause of delays.
For balance sheet preparation, year-end is prepared in October: last invoices, investment decisions, provisions to assess — December is too late to act, January is for recording.
Onnens (VD): what changes, what does not
Onnens (VD) (postal code 1425, canton Vaud) applies the same federal rules as the rest of the country: what changes in Onnens (VD) are the cantonal counterparts — tax administration, compensation office, commercial register.
For a business in Onnens (VD), that means VAT returns identical to anywhere in Switzerland, but a tax return and family allowances governed by the canton Vaud.
Frequently asked questions
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 Onnens (VD) can therefore archive fully digitally.
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 Onnens (VD): the CO dictates it, not the commune.

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 Onnens (VD) manages its documents, VAT and exports exactly as anywhere in Switzerland.
What is the difference between a limited and an ordinary audit?
The ordinary audit applies to companies exceeding, for two consecutive years, two of three thresholds: CHF 20 million balance sheet total, CHF 40 million revenue, 250 full-time positions. Others fall under the limited audit, and those with no more than ten full-time positions on annual average can opt out with all shareholders' consent. These federal thresholds do not depend on the registered seat — in Onnens (VD) as anywhere.
