Social security contributions required documents in Lully (VD) explained simply

Delegate, digitalise or do it all yourself? Around social security contributions in Lully (VD), every SME draws its own line. The reference points below — federal law, cantonal practice and lessons from the field — help you place the cursor well.

The Swiss legal frame for social security contributions

Three documents summarise the health of a Swiss business: the balance sheet (what it owns), the income statement (what it earns) and the notes (what else you should know). All the work of social security contributions converges on those three pages, in Lully (VD) too.

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.

Salaries and social contributions: the rates to know

Expense claims are payroll in the broad sense: actual reimbursements against receipts, or flat rates approved by the cantonal tax office in an expense policy. Without a clear rule, every reimbursement becomes a debate.

An often underestimated point: self-employed status is granted by the compensation office — or not. Whoever invoices essentially one main client risks requalification as an employee, with contribution arrears charged to the principal. Clarifying AHV status before starting avoids that trap.

A Swiss SME's accounting calendar

The professionals' trick: handle every deadline at D-30, not D-1. A VAT return prepared a month early leaves time to chase a missing document without penalty.

For social security contributions, deadline discipline is worth real money: default interest on late VAT, AHV adjustments, tax fines. A shared deadline calendar — fed by up-to-date figures — remains the simplest safeguard.

Digitalising social security contributions: what actually works

The classic digitalisation traps are avoidable: scanning without quality control (unreadable records), stacking disconnected tools (double entry in disguise), or neglecting access rights. One single flow from document to entry, with clear roles, beats five shiny apps.

For an owner in Lully (VD), a dashboard only has value if the data is fresh: automating data entry means, first of all, buying up-to-date information about your own business.

Lully (VD): what changes, what does not

Lully (VD) (postal code 1132, canton Vaud) applies the same federal rules as the rest of the country: what changes in Lully (VD) are the cantonal counterparts — tax administration, compensation office, commercial register.

Federal deadlines do not move in Lully (VD): VAT within 60 days, salary declaration in January, 10-year record retention — postal code 1132 changes nothing about those rules, only the sender's address.

Frequently asked questions

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 Lully (VD).

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 Lully (VD): federal law applies.

How long must records related to social security contributions 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 Lully (VD) can therefore archive fully digitally.

Do you need a fiduciary for social security contributions, or can you do it yourself?

Both are defensible. Below CHF 500,000 of revenue, a sole proprietorship may keep simplified accounts itself. As soon as payroll, VAT and a closing with tax stakes are involved, professional support prevents mistakes that cost more than the fees. With a shared platform, the fiduciary does not even need to be in Lully (VD).
