Accounting records archiving for tradespeople in Kölliken: the practical guide

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

Digitalising accounting records archiving: what actually works

Access for the fiduciary, the auditor and employees is set by roles: view, enter, approve, close. Well-set rights protect the data and speed up collaboration.

For accounting records archiving, migrating history must not block the start: begin on day one of the current financial year and import the history later if needed.

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.

The chart of accounts is also the hinge to VAT: every revenue account carries its rate (8.1%, 2.6%, 3.8% or exempt), every expense account its input-tax right. Set those attributes once in the tool and every subsequent return becomes reliable.

QR-bills and friction-free collections

Reminders work best graduated: a neutral first reminder, a firm second, then formal notice — each generated from exact balances, never from memory.

A business in Kölliken can collect by QR-bill even without sophisticated software: what matters is that every incoming payment finds its invoice, manually or automatically.

The Swiss legal frame for accounting records archiving

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

One simple principle drives accounting records archiving: 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.

Kölliken: what changes, what does not

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

Federal deadlines do not move in Kölliken: VAT within 60 days, salary declaration in January, 10-year record retention — postal code 5742 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 Kölliken as anywhere.

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 Kölliken 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 Kölliken 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 Kölliken.
