VAT registration for engineering firms in Chur without the stress: how it works

Whether you run a Sàrl, an SA or a sole proprietorship in Chur, VAT registration 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 VAT registration

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

The annual accounts (art. 958 CO) consist of the balance sheet, the income statement and the notes; they must be drawn up within six months of the year-end so the general meeting can approve them. A delay here cascades into the tax return and the final social insurance settlements.

Outsource VAT registration or keep it in-house?

Responsibility stays with the client: the fiduciary executes with care, but the signed accounts bind the company. Understanding what you sign is not optional.

For VAT registration, the internal-external duo works when both sides see the same file: same entries, same documents, same deadlines. Misunderstandings are born from parallel copies.

Swiss VAT: rates, threshold and filings

Taxable consideration is not limited to the invoiced price: barter, set-offs and benefits in kind count too. The safe reflex: every economic advantage received is documented and qualified.

For an SME in Chur, electronic filing of VAT returns has been mandatory since 1 January 2025; the tax administration's online portal is also where extensions are requested and past periods consulted. Combined with accounts that prepare the return automatically, VAT registration stops being a quarterly chore.

Digitalising VAT registration: 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 Chur 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 registration.

Chur: what changes, what does not

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

Federal deadlines do not move in Chur: VAT within 60 days, salary declaration in January, 10-year record retention — postal code 7000 changes nothing about those rules, only the sender's address.

Frequently asked questions

How long must records related to VAT registration 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 Chur can therefore archive fully digitally.

When is entry in the commercial register mandatory?

A Sàrl and an SA only come into existence with their registration. A sole proprietorship must register from CHF 100,000 of annual revenue; below that, registration stays voluntary but adds credibility and protects the business name. Registration goes through the canton's commercial register office — for Chur too.

What are the legal obligations for VAT registration in Switzerland?

The foundation is the Code of Obligations: proper bookkeeping (art. 957a CO), annual accounts (balance sheet, income statement, notes) and 10-year retention of books and records (art. 958f CO). VAT applies from CHF 100,000 of turnover, and social insurance settlements from the first employee. Nothing is different in Chur: federal law applies.
