AHV settlement for construction companies in Gunzgen: the practical guide

AHV settlement for construction companies in Gunzgen 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.

The Swiss legal frame for AHV settlement

Whether a business sits in Gunzgen or elsewhere in Switzerland, the same federal law applies — one of the strengths of the Swiss system for AHV settlement. Cantonal differences concentrate on taxation (rates, filing deadlines); bookkeeping itself follows art. 957 ff. CO everywhere.

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

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 AHV settlement, year-end is prepared in October: last invoices, investment decisions, provisions to assess — December is too late to act, January is for recording.

Digitalising AHV settlement: what actually works

Automation is judged on the exceptions: what happens when the document is unreadable, the supplier unknown, the amount divergent? A good tool isolates those cases and lets a human decide fast — precious for teams in Gunzgen.

An SME in Gunzgen that digitalises gains owner time first: less filing, fewer “where is that receipt?” questions, more attention to the trade — that is the real return of AHV settlement.

Salaries and social contributions: the rates to know

Family allowances are financed by the employer through a cantonal compensation fund — rates and amounts vary from canton to canton, including in Gunzgen. They come on top of the federal social insurances and appear on every payslip.

An employer in Gunzgen does well to fix payday on a set day of the month: funds, employees and cash flow organise around it, and AHV settlement becomes routine instead of a sprint.

Gunzgen: what changes, what does not

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

Gunzgen requires no special bookkeeping: the Code of Obligations applies at postal code 4617 as everywhere else, and a well-kept digital file transfers smoothly to any auditor in the canton.

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 Gunzgen as anywhere.

How long must records related to AHV settlement 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 Gunzgen can therefore archive fully digitally.

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 Gunzgen.

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 Gunzgen.
