Accounting records archiving for engineering firms in Tresa explained simply

Accounting records archiving for engineering firms in Tresa 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.

Digitalising accounting records archiving: what actually works

Security is part of digitalisation: named access, tested backups, encryption of sensitive data. A digital accounting file is protected like a safe — because it is one.

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

The Swiss legal frame for accounting records archiving

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

One simple principle drives accounting records archiving: every franc in or out must be explainable by a document, an entry and an account. All of Swiss accounting law fits inside that traceability requirement.

A well-structured SME chart of accounts

The same chart serves three readings: accounting (accuracy), tax (accepted adjustments) and management (margins by activity). Modern software produces all three views without double entry.

In an SME in Tresa, the chart of accounts is also a delegation tool: clear posting rules let a non-accountant prepare most entries without error.

Outsource accounting records archiving 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 records archiving lowers fees more surely than any negotiation.

A business in Tresa can combine the models: internal day-to-day entry, monthly external supervision, closing and taxes with the specialist — accounting records archiving splits very well.

Tresa: what changes, what does not

Sole proprietorship, Sàrl or SA in Tresa: the AHV contact remains the competent compensation office, and taxes follow the scales of the canton Ticino.

Tresa requires no special bookkeeping: the Code of Obligations applies at postal code 6980 as everywhere else, and a well-kept digital file transfers smoothly to any auditor in the canton.

Frequently asked questions

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 Tresa.

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 Tresa, family allowances follow the canton's rates.

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 Tresa.

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 Tresa: the CO dictates it, not the commune.
