VAT registration: when it becomes mandatory

Opening a company in Switzerland does not automatically mean being registered for VAT. Liability for value-added tax follows its own rules, tied above all to turnover. Understanding when registration becomes mandatory — and when it is worth doing early — avoids both penalties and missed opportunities to recover the tax.

The CHF 100,000 threshold

The core rule is clear: a business whose annual taxable turnover reaches CHF 100,000 becomes mandatorily liable for VAT. Below this threshold, registration is not compulsory; once it is exceeded, the obligation kicks in.

The calculation looks at taxable supplies made in Switzerland: sales of goods and services subject to tax. Not everything counts — some supplies are excluded or exempt — but the principle to keep in mind is that it is the relevant turnover that determines liability, not profit or legal form.

For certain non-profit organisations and sports or cultural associations run on a voluntary basis, a higher threshold applies; for commercial businesses in general the CHF 100,000 reference applies.

The moment the obligation kicks in

The reasoning is not “I wait until the end of the year and add up”. Liability must be assessed prospectively: anyone starting an activity must estimate whether, over the following twelve months, they will reach the threshold. If the forecast is to exceed it, the registration obligation arises from the start of the activity.

There are two typical situations:

A new business that expects taxable turnover at or above the threshold right away: it registers from the outset.
An already active business that grows and exceeds the threshold: the obligation kicks in and must be handled without delay, updating invoicing and compliance.

Ignoring the moment the obligation arises exposes you to tax reassessments and interest: VAT not collected from customers remains due all the same.

Voluntary registration

Even below CHF 100,000, a business can choose to register voluntarily. This is not a bureaucratic whim: in several cases it is worthwhile.

Recovery of input tax: a registered business can deduct the VAT paid on purchases, investments and costs (input tax). For an activity in its start-up phase, with heavy initial spending, this recovery can be significant.
Credibility with business customers: many clients expect a registered supplier, especially in B2B relationships.
Avoiding the step-up: those who know they are approaching the threshold may prefer to register early to avoid managing a transition mid-year.

The flip side is the administrative burden: periodic returns, orderly bookkeeping, managing the VAT statements. The choice should be made with the numbers, not out of habit.

What being liable entails

Once registered, the business must:

Apply VAT on taxable supplies at the correct rate (the standard rate is 8.1% as of 2024; reduced rates exist for certain goods and services).
Show the VAT number on invoices, so that liable customers can in turn recover input tax.
File the periodic returns and pay the balance due.
Keep accounting that allows output and input tax to be reconstructed.

VAT is a pass-through tax: you collect it from customers and pay it to the state, net of what you paid on your purchases. Managed well, it is neutral; managed poorly, it becomes a cash-flow problem.

In summary

The obligation kicks in on reaching CHF 100,000 of taxable turnover.
The assessment is prospective: the twelve-month forecast counts, not just the final figures.
Below the threshold you can opt for voluntary registration, useful for recovering input tax.
Liability entails correct invoicing, returns and orderly accounting.
