Fiduciary services for plumbers in Kaiseraugst: 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 fiduciary services in Kaiseraugst: what the law requires, what can be automated, and when to delegate.

The Swiss legal frame for fiduciary services

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

Art. 957a CO requires complete, truthful and systematic recording of transactions, each entry backed by a supporting document. For fiduciary services, 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.

Digitalising fiduciary services: 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 Kaiseraugst as everywhere.

For an owner in Kaiseraugst, a dashboard only has value if the data is fresh: automating data entry means, first of all, buying up-to-date information about your own business.

A Swiss SME's accounting calendar

An accounting calendar only lives if it is shared: owner, in-house bookkeeper and fiduciary must see the same deadlines and the same status — the rule holds for every SME in Kaiseraugst.

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

Outsource fiduciary services or keep it in-house?

The scope goes down in writing: who enters data, who approves payments, who answers the tax office, who keeps the originals. Every “we'll see” at the start becomes a December misunderstanding — in Kaiseraugst as elsewhere.

Changing fiduciary is not a drama: the accounting data belongs to the company, and a clean export (entries, chart of accounts, linked documents) allows a transition at year-end. A provider who locks in a client's data says a lot about how it works.

Kaiseraugst: what changes, what does not

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

Federal deadlines do not move in Kaiseraugst: VAT within 60 days, salary declaration in January, 10-year record retention — postal code 4303 changes nothing about those rules, only the sender's address.

Yes: the platform runs online, the rules applied are federal (VAT, CO, AHV), and the file can be shared with any fiduciary. A business in Kaiseraugst manages its documents, VAT and exports exactly as anywhere in Switzerland.

It depends on document volume, the number of salaries and VAT complexity — no serious figure can be quoted without examining the file. Two levers cut the bill everywhere: digitised, well-filed receipts and software that prepares entries instead of having them re-keyed.

Which social contributions does a Swiss employer pay?

AHV/IV/APG: 5.3% employer share (the same is withheld from the employee); unemployment insurance: 1.1% each up to CHF 148,200 a year; occupational pension (LPP) by age and plan (employer at least 50%); occupational accident insurance paid by the employer; family allowances by canton. For an employer in Kaiseraugst, family allowances follow the canton's rates.

How long must records related to fiduciary services 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 Kaiseraugst can therefore archive fully digitally.
