AHV settlement how to choose in Collex-Bossy: rules, deadlines, best practice
Delegate, digitalise or do it all yourself? Around AHV settlement in Collex-Bossy, 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 AHV settlement
A small business does not mean small obligations: from the first salary or the first VAT return, mistakes get expensive — in Collex-Bossy as anywhere.
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.
Digitalising AHV settlement: what actually works
Artificial intelligence has changed the economics of AHV settlement: automatic invoice reading reaches recognition rates that make manual entry marginal, and posting suggestions learn from corrections. The accountant does not disappear — the job shifts from data entry to control and advice.
For AHV settlement, migrating history must not block the start: begin on day one of the current financial year and import the history later if needed.
Outsource AHV settlement 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 AHV settlement lowers fees more surely than any negotiation.
For AHV settlement, a quarterly 30-minute check-in with the fiduciary beats an annual marathon: questions get handled while they are small.

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 Collex-Bossy. They come on top of the federal social insurances and appear on every payslip.
For AHV settlement, the monthly payslip is only the visible part: instalments to the funds, annual settlements and certificates form the real cycle, January to January.
Collex-Bossy: what changes, what does not
Working with a fiduciary from Collex-Bossy no longer depends on geography: the documents of a business in Collex-Bossy are shared online, while the canton Geneva keeps its own deadlines for the tax return.
For a business in Collex-Bossy, that means VAT returns identical to anywhere in Switzerland, but a tax return and family allowances governed by the canton Geneva.
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 Collex-Bossy.
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 Collex-Bossy as anywhere.
Do you need a fiduciary for AHV settlement, 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 Collex-Bossy.
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 Collex-Bossy, family allowances follow the canton's rates.
