Accounting outsourcing legal basis in Premier: the practical guide

Accounting outsourcing legal basis in Premier raises the same questions for most Swiss SME owners: which obligations apply, which deadlines are running, which documents to prepare. This page covers the federal rules in force — without unnecessary jargon.

The Swiss legal frame for accounting outsourcing

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

Late books show from the outside: poorly calibrated tax instalments, provisional filings, slow answers to the bank. Staying current is also a matter of image.

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 Premier) and internal (closing, general meeting within six months). Mixing them up is the leading cause of delays.

An SME in Premier that holds its calendar twelve months straight changes its position: fewer official reminders, easier extensions — and accounting outsourcing stops being a source of worry.

Year-end closing: how the mechanics work

The closing is prepared all year long: a monthly bank reconciliation and accruals tracked as you go turn the year-end into a formality, for businesses in Premier too.

A company in Premier that presents clean, punctual annual accounts gains credibility — with its bank, its suppliers and the tax administration.

Digitalising accounting outsourcing: what actually works

The classic digitalisation traps are avoidable: scanning without quality control (unreadable records), stacking disconnected tools (double entry in disguise), or neglecting access rights. One single flow from document to entry, with clear roles, beats five shiny apps.

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

Premier: what changes, what does not

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

Premier requires no special bookkeeping: the Code of Obligations applies at postal code 1324 as everywhere else, and a well-kept digital file transfers smoothly to any auditor in the canton.

Frequently asked questions

How long must records related to accounting outsourcing 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 Premier can therefore archive fully digitally.

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 Premier.

Do you need a fiduciary for accounting outsourcing, 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 Premier.

What are the legal obligations for accounting outsourcing 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 Premier: federal law applies.
