Everything that matters about salary certificate for plumbers in Cornaux

Whether you run a Sàrl, an SA or a sole proprietorship in Cornaux, 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

For an owner in Cornaux, the question is never “do we need accounts?” but “at what level of detail?”. The CO sets the floor; the bank, the tax office and the shareholders set the rest.

Also worth knowing: accounts may be drawn up in the currency most relevant to the business; if that is not the franc, values must additionally be stated in CHF (art. 958d para. 3 CO). Internationally active companies gain books that match their economic reality.

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.

The useful reflex: date every obligation the moment it arises. An employee hired means AHV/LPP deadlines created; VAT registration means a filing cycle set; a closing date fixed means backward planning of the close. Well organised, the salary certificate calendar fills itself.

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.

The winning pair for salary certificate: a single inbox (e-mail, scan, photo) and one simple rule — no document sits more than a few days without a proposed entry.

Salaries and social contributions: the rates to know

Family allowances are financed by the employer through a cantonal compensation fund — rates and amounts vary from canton to canton, including in Cornaux. They come on top of the federal social insurances and appear on every payslip.

A thirteenth salary, where agreed, is accrued month by month — forget it and December reveals a charge of one-twelfth of the payroll, in Cornaux as everywhere.

Cornaux: what changes, what does not

Sole proprietorship, Sàrl or SA in Cornaux: the AHV contact remains the competent compensation office, and taxes follow the scales of the canton Neuchâtel.

Cornaux requires no special bookkeeping: the Code of Obligations applies at postal code 2087 as everywhere else, and a well-kept digital file transfers smoothly to any auditor in the canton.
