Salary certificate legal obligations in Baden: rules, deadlines, best practice

Between VAT, social contributions and the year-end close, a Swiss SME juggles dozens of deadlines a year. This page focuses on salary certificate in Baden: what the law requires, what can be automated, and when to delegate.

The Swiss legal frame for salary certificate

A small business does not mean small obligations: from the first salary or the first VAT return, mistakes get expensive — in Baden as anywhere.

The good news: the Swiss frame is stable and predictable. Structure salary certificate once — chart of accounts, document flow, calendar — and the same organisation pays off for years.

Digitalising salary certificate: what actually works

A serious accounting document archive links every record to its entry, timestamps versions and logs access — exactly what Swiss bookkeeping regulation expects from probative electronic retention. Chronological filing by financial year becomes an automatic by-product.

For salary certificate, migrating history must not block the start: begin on day one of the current financial year and import the history later if needed.

Outsource salary certificate or keep it in-house?

The Swiss fiduciary market is dense and governed by professional practice: industry standards, business secrecy, civil liability. Compare offers on three concrete criteria — exact scope (data entry? closing? payroll? VAT?), a named contact person, and the tools used. It prevents year-end misunderstandings.

For salary certificate, 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 Baden. They come on top of the federal social insurances and appear on every payslip.

An often underestimated point: self-employed status is granted by the compensation office — or not. Whoever invoices essentially one main client risks requalification as an employee, with contribution arrears charged to the principal. Clarifying AHV status before starting avoids that trap.

Baden: what changes, what does not

Baden (postal code 5300, canton Aargau) applies the same federal rules as the rest of the country: what changes in Baden are the cantonal counterparts — tax administration, compensation office, commercial register.

Federal deadlines do not move in Baden: VAT within 60 days, salary declaration in January, 10-year record retention — postal code 5300 changes nothing about those rules, only the sender's address.

Frequently asked questions

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 Baden as anywhere.

Do you need a fiduciary for salary certificate, 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 Baden.

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 Baden.

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 Baden.
