AHV settlement for architecture firms in Lignières: rules, deadlines, best practice

Delegate, digitalise or do it all yourself? Around AHV settlement in Lignières, 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

AHV audits and VAT audits follow the same logic: start from the documents, trace to the entries, check consistency. A business in Lignières with a clean audit trail sails through these exercises.

Art. 957a CO requires complete, truthful and systematic recording of transactions, each entry backed by a supporting document. For AHV settlement, that means in practice: no movement without a receipt, and an audit trail that can be reconstructed at any time — including during a VAT or AHV inspection.

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

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.

Electronic archiving is fully recognised: Swiss bookkeeping regulation admits electronic retention of records provided integrity and readability are guaranteed for the 10 years of art. 958f CO. A paper binder is no longer an obligation — provided the archiving system is serious.

Outsource AHV settlement or keep it in-house?

Outsourcing does not exempt you from understanding: an owner who can read the balance sheet and the income statement challenges the fiduciary better — and pays for advice, not re-keying.

A business in Lignières can combine the models: internal day-to-day entry, monthly external supervision, closing and taxes with the specialist — AHV settlement splits very well.

Lignières: what changes, what does not

Working with a fiduciary from Lignières no longer depends on geography: the documents of a business in Lignières are shared online, while the canton Neuchâtel keeps its own deadlines for the tax return.

For a business in Lignières, that means VAT returns identical to anywhere in Switzerland, but a tax return and family allowances governed by the canton Neuchâtel.

Frequently asked questions

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 Lignières can therefore archive fully digitally.

Does MyFiducia.ai work for a business based in Lignières?

Yes: the platform runs online, the rules applied are federal (VAT, CO, AHV), and the file can be shared with any fiduciary. A business in Lignières manages its documents, VAT and exports exactly as anywhere in Switzerland.

Effective VAT method or net tax rate: how to choose?

The effective method deducts actual input VAT and files quarterly; the net tax rate method applies a flat industry rate to turnover, semi-annually, with no separate input VAT deduction. The flat rate suits low-cost structures; as investments grow, the effective method usually wins again. The choice rests on the company's own figures, in Lignières as anywhere.

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 Lignières.
