Salary certificate comparison in Mex (VD): rules, deadlines, best practice
Whether you run a Sàrl, an SA or a sole proprietorship in Mex (VD), salary certificate 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 salary certificate
Whether a business sits in Mex (VD) or elsewhere in Switzerland, the same federal law applies — one of the strengths of the Swiss system for salary certificate. Cantonal differences concentrate on taxation (rates, filing deadlines); bookkeeping itself follows art. 957 ff. CO everywhere.
For salary certificate, the classic early mistake remains mixing private and business: a dedicated bank account and documented private withdrawals eliminate half the discussions with the tax office.
Outsource salary certificate or keep it in-house?
A fiduciary's cost depends first on the quality of the data received: digitised, filed, reconciled documents are processed fast; a box of loose receipts is billed by the hour. Improving the internal preparation of salary certificate lowers fees more surely than any negotiation.
A business in Mex (VD) is no longer limited to fiduciaries in its canton: with a shared online platform, collaboration works remotely, documents and entries visible to both sides in real time. The choice widens to all of Switzerland — competence becomes the criterion again, not the postcode.
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 Mex (VD) that holds its calendar twelve months straight changes its position: fewer official reminders, easier extensions — and salary certificate stops being a source of worry.

Digitalising salary certificate: what actually works
Security is part of digitalisation: named access, tested backups, encryption of sensitive data. A digital accounting file is protected like a safe — because it is one.
For an owner in Mex (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.
Mex (VD): what changes, what does not
Working with a fiduciary from Mex (VD) no longer depends on geography: the documents of a business in Mex (VD) are shared online, while the canton Vaud keeps its own deadlines for the tax return.
Federal deadlines do not move in Mex (VD): VAT within 60 days, salary declaration in January, 10-year record retention — postal code 1031 changes nothing about those rules, only the sender's address.
Frequently asked questions
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 Mex (VD) too.
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 Mex (VD) as anywhere.
