Social security contributions legal basis in La Chaux-du-Milieu explained simply
Social security contributions legal basis in La Chaux-du-Milieu raises the same questions for most Swiss SME owners: which obligations apply, which deadlines are running, which documents to prepare. This page covers the federal rules in force — without unnecessary jargon.
The Swiss legal frame for social security contributions
Whether a business sits in La Chaux-du-Milieu or elsewhere in Switzerland, the same federal law applies — one of the strengths of the Swiss system for social security contributions. Cantonal differences concentrate on taxation (rates, filing deadlines); bookkeeping itself follows art. 957 ff. CO everywhere.
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.
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 employer in La Chaux-du-Milieu does well to fix payday on a set day of the month: funds, employees and cash flow organise around it, and social security contributions becomes routine instead of a sprint.
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 La Chaux-du-Milieu 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.

Digitalising social security contributions: what actually works
Accounting digitalisation always follows the same path: capture documents at the source (photo or PDF upload), let automatic recognition extract supplier, amount, date and VAT, approve the proposed entries, then archive each document linked to its entry. Every step removes a re-keying — and therefore an error source.
The winning pair for social security contributions: a single inbox (e-mail, scan, photo) and one simple rule — no document sits more than a few days without a proposed entry.
La Chaux-du-Milieu: what changes, what does not
Working with a fiduciary from La Chaux-du-Milieu no longer depends on geography: the documents of a business in La Chaux-du-Milieu are shared online, while the canton Neuchâtel keeps its own deadlines for the tax return.
Federal deadlines do not move in La Chaux-du-Milieu: VAT within 60 days, salary declaration in January, 10-year record retention — postal code 2405 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 La Chaux-du-Milieu.
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 La Chaux-du-Milieu too.
When must a business register for VAT?
As soon as its worldwide annual turnover reaches CHF 100,000 (CHF 250,000 for non-profit sports or cultural associations). Below that, voluntary registration remains possible and often makes sense to reclaim input VAT on investments. The threshold is federal: it applies in La Chaux-du-Milieu as everywhere in Switzerland.
Which social contributions does a Swiss employer pay?
AHV/IV/APG: 5.3% employer share (the same is withheld from the employee); unemployment insurance: 1.1% each up to CHF 148,200 a year; occupational pension (LPP) by age and plan (employer at least 50%); occupational accident insurance paid by the employer; family allowances by canton. For an employer in La Chaux-du-Milieu, family allowances follow the canton's rates.
