Annual accounts paperless in Mellingen: what every SME should know

Between VAT, social contributions and the year-end close, a Swiss SME juggles dozens of deadlines a year. This page focuses on annual accounts in Mellingen: what the law requires, what can be automated, and when to delegate.

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.

For annual accounts, a closing checklist reused every year transforms the exercise: same steps, same checks, same documents — only the year changes.

Outsource annual accounts or keep it in-house?

Outsourcing does not exempt you from understanding: an owner who can read the balance sheet and the income statement challenges the fiduciary better — and pays for advice, not re-keying.

Three signals say it is time to delegate more: missed deadlines (VAT, AHV), entries running months behind, or an owner spending evenings on receipts instead of the business. Conversely, an SME equipped with modern software can safely take day-to-day entry back in-house.

The Swiss legal frame for annual accounts

AHV audits and VAT audits follow the same logic: start from the documents, trace to the entries, check consistency. A business in Mellingen with a clean audit trail sails through these exercises.

The good news: the Swiss frame is stable and predictable. Structure annual accounts once — chart of accounts, document flow, calendar — and the same organisation pays off for years.

Every deadline has an owner: an obligation “of everyone” is kept by no one. Naming one person per deadline family (VAT, payroll, taxes) closes the gaps.

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

Mellingen: what changes, what does not

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

For a business in Mellingen, that means VAT returns identical to anywhere in Switzerland, but a tax return and family allowances governed by the canton Aargau.

Frequently asked questions

Which social contributions does a Swiss employer pay?

AHV/IV/APG: 5.3% employer share (the same is withheld from the employee); unemployment insurance: 1.1% each up to CHF 148,200 a year; occupational pension (LPP) by age and plan (employer at least 50%); occupational accident insurance paid by the employer; family allowances by canton. For an employer in Mellingen, family allowances follow the canton's rates.

What are the current Swiss VAT rates?

Since 1 January 2024: 8.1% (standard), 2.6% (reduced — for example food and medicines) and 3.8% (accommodation). Returns must be filed and paid within 60 days after the period ends (quarterly under the effective method, semi-annually under the net tax rate method). These federal rates apply unchanged in Mellingen.

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 Mellingen: the CO dictates it, not the commune.

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 Mellingen as anywhere.
