Social security contributions for architecture firms in Dardagny: 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 social security contributions in Dardagny: what the law requires, what can be automated, and when to delegate.
The Swiss legal frame for social security contributions
A small business does not mean small obligations: from the first salary or the first VAT return, mistakes get expensive — in Dardagny as anywhere.
The law also settles the form: accounts may be kept in a national language or in English, on paper or electronically (art. 957a para. 5 CO). That pragmatism lets social security contributions run entirely on digital tools — no paper binder is required.
Outsource social security contributions or keep it in-house?
A good test before choosing: ask the fiduciary HOW it wants to receive the documents. A precise answer (formats, frequency, platform) says more than any brochure — including in Dardagny.
A business in Dardagny can combine the models: internal day-to-day entry, monthly external supervision, closing and taxes with the specialist — social security contributions splits very well.
Salaries and social contributions: the rates to know
Hiring the first employee triggers everything at once: affiliation to AHV and LPP funds, accident insurance, family allowances, working-time rules. A complete payroll file from day one avoids catch-ups.
For social security contributions, the monthly payslip is only the visible part: instalments to the funds, annual settlements and certificates form the real cycle, January to January.

Digitalising social security contributions: what actually works
Digitising does not mean hoarding PDFs: without the document-entry link, a digital file is as opaque as a box of archives — true in Dardagny as everywhere.
For social security contributions, migrating history must not block the start: begin on day one of the current financial year and import the history later if needed.
Dardagny: what changes, what does not
Dardagny (postal code 1283, canton Geneva) applies the same federal rules as the rest of the country: what changes in Dardagny are the cantonal counterparts — tax administration, compensation office, commercial register.
Dardagny requires no special bookkeeping: the Code of Obligations applies at postal code 1283 as everywhere else, and a well-kept digital file transfers smoothly to any auditor in the canton.
Frequently asked questions
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 Dardagny: the CO dictates it, not the commune.
What are the legal obligations for social security contributions in Switzerland?
The foundation is the Code of Obligations: proper bookkeeping (art. 957a CO), annual accounts (balance sheet, income statement, notes) and 10-year retention of books and records (art. 958f CO). VAT applies from CHF 100,000 of turnover, and social insurance settlements from the first employee. Nothing is different in Dardagny: federal law applies.
