Limited statutory audit for garages in Lonay: the practical guide

Limited statutory audit for garages in Lonay 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.

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.

The Swiss legal frame for limited statutory audit

A small business does not mean small obligations: from the first salary or the first VAT return, mistakes get expensive — in Lonay as anywhere.

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.

A well-structured SME chart of accounts

Account labels deserve as much care as numbers: “Third-party fees” says nothing, “Fiduciary fees” and “IT fees” say everything. Meaningful labels cut posting errors and make dashboards readable without a glossary.

For limited statutory audit, the right granularity is decisive: enough accounts to steer the business (margins by activity, expenses by nature), few enough that every entry finds its place without hesitation. The VAT accounts (input VAT, VAT due) deserve special care — they are the basis of the annual reconciliation.

The professionals' trick: handle every deadline at D-30, not D-1. A VAT return prepared a month early leaves time to chase a missing document without penalty.

For limited statutory audit, two dates lock themselves in every year: the January salary declaration and the general meeting within six months — everything else is planned around them.

Lonay: what changes, what does not

Sole proprietorship, Sàrl or SA in Lonay: the AHV contact remains the competent compensation office, and taxes follow the scales of the canton Vaud.

Federal deadlines do not move in Lonay: VAT within 60 days, salary declaration in January, 10-year record retention — postal code 1027 changes nothing about those rules, only the sender's address.

Frequently asked questions

Effective VAT method or net tax rate: how to choose?

The effective method deducts actual input VAT and files quarterly; the net tax rate method applies a flat industry rate to turnover, semi-annually, with no separate input VAT deduction. The flat rate suits low-cost structures; as investments grow, the effective method usually wins again. The choice rests on the company's own figures, in Lonay as anywhere.

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 Lonay too.

How long must records related to limited statutory audit 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 Lonay can therefore archive fully digitally.

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 Lonay.
