Payroll administration for e-commerce in Reinach (BL): rules, deadlines, best practice

Delegate, digitalise or do it all yourself? Around payroll administration in Reinach (BL), 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 payroll administration

AHV audits and VAT audits follow the same logic: start from the documents, trace to the entries, check consistency. A business in Reinach (BL) 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 payroll administration, 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.

Outsource payroll administration or keep it in-house?

A good test before choosing: ask the fiduciary HOW it wants to receive the documents. A precise answer (formats, frequency, platform) says more than any brochure — including in Reinach (BL).

A business in Reinach (BL) can combine the models: internal day-to-day entry, monthly external supervision, closing and taxes with the specialist — payroll administration splits very well.

A Swiss SME's accounting calendar

Three families of deadlines shape the year: federal (VAT within 60 days, salary declaration in January), cantonal (tax return, extensions depending on the canton, including in Reinach (BL)) and internal (closing, general meeting within six months). Mixing them up is the leading cause of delays.

An SME in Reinach (BL) that holds its calendar twelve months straight changes its position: fewer official reminders, easier extensions — and payroll administration stops being a source of worry.

Digitalising payroll administration: what actually works

Digitising does not mean hoarding PDFs: without the document-entry link, a digital file is as opaque as a box of archives — true in Reinach (BL) as everywhere.

Migrate in stages: supplier invoices first (high volume, immediate gain), then receivables with the QR-bill, finally payroll and the closing. At each stage, comparing one month before/after is enough to prove the gain — no theoretical promises needed.

Reinach (BL): what changes, what does not

Sole proprietorship, Sàrl or SA in Reinach (BL): the AHV contact remains the competent compensation office, and taxes follow the scales of the canton Basel-Country.

For a business in Reinach (BL), that means VAT returns identical to anywhere in Switzerland, but a tax return and family allowances governed by the canton Basel-Country.

Frequently asked questions

How long must records related to payroll administration 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 Reinach (BL) can therefore archive fully digitally.

What are the legal obligations for payroll administration in Switzerland?

The foundation is the Code of Obligations: proper bookkeeping (art. 957a CO), annual accounts (balance sheet, income statement, notes) and 10-year retention of books and records (art. 958f CO). VAT applies from CHF 100,000 of turnover, and social insurance settlements from the first employee. Nothing is different in Reinach (BL): federal law applies.

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 Reinach (BL) as anywhere.

Do you need a fiduciary for payroll administration, 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 Reinach (BL).
