Payroll administration in real time in Martigny: rules, deadlines, best practice
Between VAT, social contributions and the year-end close, a Swiss SME juggles dozens of deadlines a year. This page focuses on payroll administration in Martigny: what the law requires, what can be automated, and when to delegate.
The Swiss legal frame for payroll administration
AHV audits and VAT audits follow the same logic: start from the documents, trace to the entries, check consistency. A business in Martigny with a clean audit trail sails through these exercises.
The good news: the Swiss frame is stable and predictable. Structure payroll administration once — chart of accounts, document flow, calendar — and the same organisation pays off for years.
Outsource payroll administration or keep it in-house?
The scope goes down in writing: who enters data, who approves payments, who answers the tax office, who keeps the originals. Every “we'll see” at the start becomes a December misunderstanding — in Martigny as elsewhere.
A business in Martigny can combine the models: internal day-to-day entry, monthly external supervision, closing and taxes with the specialist — payroll administration 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.
A thirteenth salary, where agreed, is accrued month by month — forget it and December reveals a charge of one-twelfth of the payroll, in Martigny as everywhere.
A Swiss SME's accounting calendar
January: salary declaration to the compensation office and salary certificates. End of February, May, August, November: quarterly VAT returns (effective method), each to be filed and paid within 60 days after the quarter ends. Within six months of year-end: approved annual accounts. Then: the tax return under cantonal deadlines, with extensions possible.
An SME in Martigny that holds its calendar twelve months straight changes its position: fewer official reminders, easier extensions — and payroll administration stops being a source of worry.
Martigny: what changes, what does not
Sole proprietorship, Sàrl or SA in Martigny: the AHV contact remains the competent compensation office, and taxes follow the scales of the canton Valais.
Martigny requires no special bookkeeping: the Code of Obligations applies at postal code 1906 as everywhere else, and a well-kept digital file transfers smoothly to any auditor in the canton.
Frequently asked questions
What are the legal obligations for payroll administration 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 Martigny: federal law applies.
What is the difference between a limited and an ordinary audit?
The ordinary audit applies to companies exceeding, for two consecutive years, two of three thresholds: CHF 20 million balance sheet total, CHF 40 million revenue, 250 full-time positions. Others fall under the limited audit, and those with no more than ten full-time positions on annual average can opt out with all shareholders' consent. These federal thresholds do not depend on the registered seat — in Martigny as anywhere.
Does MyFiducia.ai work for a business based in Martigny?
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 Martigny manages its documents, VAT and exports exactly as anywhere in Switzerland.
When is entry in the commercial register mandatory?
A Sàrl and an SA only come into existence with their registration. A sole proprietorship must register from CHF 100,000 of annual revenue; below that, registration stays voluntary but adds credibility and protects the business name. Registration goes through the canton's commercial register office — for Martigny too.
