AHV settlement for retail in Lostorf: rules, deadlines, best practice
Swiss accounting law (art. 957 ff. of the Code of Obligations) sets a precise frame, yet day-to-day practice often stays fuzzy. This guide walks through what actually matters for a business based in Lostorf.
The Swiss legal frame for AHV settlement
AHV audits and VAT audits follow the same logic: start from the documents, trace to the entries, check consistency. A business in Lostorf with a clean audit trail sails through these exercises.
For AHV settlement, 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.
Salaries and social contributions: the rates to know
Absences are managed upstream: illness, accident, military service or maternity trigger allowances (APG, insurance) that replace part of the salary. Clean absence records are the basis of correct settlements, in Lostorf as elsewhere.
An employer in Lostorf does well to fix payday on a set day of the month: funds, employees and cash flow organise around it, and AHV settlement 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.
For AHV settlement, two dates lock themselves in every year: the January salary declaration and the general meeting within six months — everything else is planned around them.

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.
Lostorf: what changes, what does not
Sole proprietorship, Sàrl or SA in Lostorf: the AHV contact remains the competent compensation office, and taxes follow the scales of the canton Solothurn.
Lostorf requires no special bookkeeping: the Code of Obligations applies at postal code 4654 as everywhere else, and a well-kept digital file transfers smoothly to any auditor in the canton.
Frequently asked questions
What are the current Swiss VAT rates?
Since 1 January 2024: 8.1% (standard), 2.6% (reduced — for example food and medicines) and 3.8% (accommodation). Returns must be filed and paid within 60 days after the period ends (quarterly under the effective method, semi-annually under the net tax rate method). These federal rates apply unchanged in Lostorf.
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 Lostorf 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 Lostorf.
How long must records related to AHV settlement be kept?
Ten years from the end of the financial year concerned (art. 958f CO). Electronic retention is permitted if the integrity and readability of the records are guaranteed — a serious digital archive validly replaces paper binders. A business in Lostorf can therefore archive fully digitally.
