VAT return deadlines in Wängi explained simply

Between VAT, social contributions and the year-end close, a Swiss SME juggles dozens of deadlines a year. This page focuses on VAT return in Wängi: what the law requires, what can be automated, and when to delegate.

The Swiss legal frame for VAT return

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 Wängi.

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

Swiss VAT: rates, threshold and filings

The most frequent VAT mistakes are well known: the wrong rate among 8.1%, 2.6% and 3.8%, forgotten self-supplies, and a rushed annual reconciliation. Corrections are due at the latest in the return for the period containing the 180th day after the year-end — the earlier you correct, the less default interest runs.

A business in Wängi that crosses the threshold mid-year must register without delay: retroactive registration with interest always costs more than signing up on time.

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.

For VAT return, two dates lock themselves in every year: the January salary declaration and the general meeting within six months — everything else is planned around them.

Digitalising VAT return: 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.

An SME in Wängi 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 VAT return.

Wängi: what changes, what does not

Wängi (postal code 9545, canton Thurgau) applies the same federal rules as the rest of the country: what changes in Wängi are the cantonal counterparts — tax administration, compensation office, commercial register.

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

Frequently asked questions

How long must records related to VAT return 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 Wängi can therefore archive fully digitally.

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 Wängi.

Can VAT return be automated with AI?

Largely, yes: automatic document reading, posting suggestions, bank reconciliation via QR references and VAT exports. Human approval remains essential — AI prepares, the professional checks. That is exactly how MyFiducia.ai approaches VAT return.

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 Wängi, family allowances follow the canton's rates.
