Everything that matters about social security contributions legal basis in Lussy-sur-Morges
Whether you run a Sàrl, an SA or a sole proprietorship in Lussy-sur-Morges, social security contributions eventually lands on your desk. Here are the practical reference points — legal basis, deadlines and common pitfalls — to decide with a clear head.
The Swiss legal frame for social security contributions
AHV audits and VAT audits follow the same logic: start from the documents, trace to the entries, check consistency. A business in Lussy-sur-Morges with a clean audit trail sails through these exercises.
Art. 957a CO requires complete, truthful and systematic recording of transactions, each entry backed by a supporting document. For social security contributions, 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.
Digitalising social security contributions: what actually works
Artificial intelligence has changed the economics of social security contributions: automatic invoice reading reaches recognition rates that make manual entry marginal, and posting suggestions learn from corrections. The accountant does not disappear — the job shifts from data entry to control and advice.
An SME in Lussy-sur-Morges 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 social security contributions.
Outsource social security contributions or keep it in-house?
The Swiss fiduciary market is dense and governed by professional practice: industry standards, business secrecy, civil liability. Compare offers on three concrete criteria — exact scope (data entry? closing? payroll? VAT?), a named contact person, and the tools used. It prevents year-end misunderstandings.
For social security contributions, the internal-external duo works when both sides see the same file: same entries, same documents, same deadlines. Misunderstandings are born from parallel copies.

A Swiss SME's accounting calendar
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.
An SME in Lussy-sur-Morges that holds its calendar twelve months straight changes its position: fewer official reminders, easier extensions — and social security contributions stops being a source of worry.
Lussy-sur-Morges: what changes, what does not
Lussy-sur-Morges (postal code 1167, canton Vaud) applies the same federal rules as the rest of the country: what changes in Lussy-sur-Morges are the cantonal counterparts — tax administration, compensation office, commercial register.
Federal deadlines do not move in Lussy-sur-Morges: VAT within 60 days, salary declaration in January, 10-year record retention — postal code 1167 changes nothing about those rules, only the sender's address.
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 Lussy-sur-Morges: the CO dictates it, not the commune.
Can social security contributions be automated with AI?
Largely, yes: automatic document reading, posting suggestions, bank reconciliation via QR references and VAT exports. Human approval remains essential — AI prepares, the professional checks. That is exactly how MyFiducia.ai approaches social security contributions.
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 Lussy-sur-Morges: federal law applies.

Yes: the platform runs online, the rules applied are federal (VAT, CO, AHV), and the file can be shared with any fiduciary. A business in Lussy-sur-Morges manages its documents, VAT and exports exactly as anywhere in Switzerland.
