Fiduciary services automation in Spreitenbach without the stress: how it works

Whether you run a Sàrl, an SA or a sole proprietorship in Spreitenbach, fiduciary services eventually lands on your desk. Here are the practical reference points — legal basis, deadlines and common pitfalls — to decide with a clear head.

The Swiss legal frame for fiduciary services

Responsibility for the books is personal: in an SA, organising the accounting is one of the board's non-transferable duties (art. 716a CO); in a Sàrl, the managing directors carry the same duty. Outsourcing the execution never transfers that underlying responsibility, including for a company based in Spreitenbach.

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

Outsource fiduciary services or keep it in-house?

Outsourcing fiduciary services to a fiduciary frees up time and secures compliance; keeping it in-house preserves a continuous view and costs less in fees. The best answer is often hybrid: the company captures and digitises as it goes, the fiduciary supervises, closes the books and represents the company before the authorities.

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

Digitalising fiduciary services: 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.

An SME in Spreitenbach that digitalises gains owner time first: less filing, fewer “where is that receipt?” questions, more attention to the trade — that is the real return of fiduciary services.

A Swiss SME's accounting calendar

Extensions exist and can be requested: cantonal deadlines for the tax return, deferral of the VAT filing on a reasoned request. But an extension does not stop interest: on VAT, default interest runs from the ordinary due date even when more time has been granted.

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

Spreitenbach: what changes, what does not

Spreitenbach (postal code 8957, canton Aargau) applies the same federal rules as the rest of the country: what changes in Spreitenbach are the cantonal counterparts — tax administration, compensation office, commercial register.

Federal deadlines do not move in Spreitenbach: VAT within 60 days, salary declaration in January, 10-year record retention — postal code 8957 changes nothing about those rules, only the sender's address.

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 Spreitenbach: the CO dictates it, not the commune.

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 Spreitenbach.

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 Spreitenbach.

When must a business register for VAT?

As soon as its worldwide annual turnover reaches CHF 100,000 (CHF 250,000 for non-profit sports or cultural associations). Below that, voluntary registration remains possible and often makes sense to reclaim input VAT on investments. The threshold is federal: it applies in Spreitenbach as everywhere in Switzerland.
