Accounting outsourcing legal obligations in Altnau: 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 accounting outsourcing in Altnau: what the law requires, what can be automated, and when to delegate.

The Swiss legal frame for accounting outsourcing

Three documents summarise the health of a Swiss business: the balance sheet (what it owns), the income statement (what it earns) and the notes (what else you should know). All the work of accounting outsourcing converges on those three pages, in Altnau too.

The law also settles the form: accounts may be kept in a national language or in English, on paper or electronically (art. 957a para. 5 CO). That pragmatism lets accounting outsourcing run entirely on digital tools — no paper binder is required.

Outsource accounting outsourcing or keep it in-house?

A fiduciary's cost depends first on the quality of the data received: digitised, filed, reconciled documents are processed fast; a box of loose receipts is billed by the hour. Improving the internal preparation of accounting outsourcing lowers fees more surely than any negotiation.

Three signals say it is time to delegate more: missed deadlines (VAT, AHV), entries running months behind, or an owner spending evenings on receipts instead of the business. Conversely, an SME equipped with modern software can safely take day-to-day entry back in-house.

Digitalising accounting outsourcing: what actually works

Artificial intelligence has changed the economics of accounting outsourcing: 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 an SME in Altnau, the real gain of digitalised accounting outsourcing shows day to day: no paper pile at month-end, VAT prepared continuously, and an owner reading today's figures rather than last quarter's.

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

For accounting outsourcing, year-end is prepared in October: last invoices, investment decisions, provisions to assess — December is too late to act, January is for recording.

Altnau: what changes, what does not

Altnau (postal code 8595, canton Thurgau) applies the same federal rules as the rest of the country: what changes in Altnau are the cantonal counterparts — tax administration, compensation office, commercial register.

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

Frequently asked questions

Which documents should be prepared for the year-end closing?

Bank and cash statements at the closing date, the inventory of stock and work in progress, final AHV/LPP/accident settlements, contracts signed or amended during the year, invoices straddling two years and the detail of accruals. With an up-to-date document archive, most of it is already there. The list is identical in Altnau: the CO dictates it, not the commune.

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 Altnau.
