Choosing a Domicile Canton for a New Swiss Company

Published rankings of "the cheapest canton for a Swiss company" put a single percentage next to each canton's name, and founders read them as directly comparable. They aren't, and the reason is structural rather than a matter of which canton happens to be cheapest this year. In most cantons the rate in the law is only a starting point: a base rate that gets multiplied by a Steuerfuss the canton and the commune set separately, moving from year to year and from one commune to the next within the same canton. A handful of cantons instead fix one rate outright. A number quoted for a canton without naming the commune and the year is one snapshot of a moving target, and the two kinds of number are not the same kind of thing.

The federal layer is the same everywhere#

One part of the bill doesn't vary by canton at all. The direct federal tax on a capital company's net profit is a flat 8.5%, set by Art. 68 DBG and capped there by the federal constitution itself (Art. 128 Abs. 1 Bst. b BV), identical whether the company is domiciled in Stans, Zug, or Zurich. Whatever difference exists between cantons comes entirely from the cantonal and communal layer on top of that 8.5%, and only from that layer.

A canton with no multiplier at all#

Nidwalden is the clearest example of the fixed-rate structure. Its cantonal profit tax for a capital company is set directly in law at 5.1% of net profit (Art. 85 StG), and unlike most cantons it isn't multiplied by anything: the canton's own published 2026 table for cantonal capitals lists it as applying no Steuerfuss at either the cantonal or communal level. The 5.1% already covers canton, commune and church between them, split administratively rather than layered on top of each other. Capital tax follows the same fixed-rate logic: 0.1‰ of taxable equity, with a combined minimum annual tax of CHF 500 (Art. 98 StG).

The more common case: a rate that moves with the commune#

Zug and Zurich work the other way. Each sets a base rate in law (3.5% in Zug, § 66 StG; 7% in Zurich, § 71 StG, covering both cantons' capital companies), and that base rate is then multiplied separately by a cantonal Steuerfuss and by whatever the specific commune has set for itself. In Zug's own cantonal capital, the 2026 cantonal multiplier is 78%, cut from the 82% statutory default for the 2026-2029 period; Zug city's communal multiplier sits at 52.11%. In Zurich city, the cantonal multiplier is 95% and the communal multiplier is 119%, more than double Zug city's. Move the same company to a different commune within either canton and both multipliers change again.

The multiplier is also what makes a single published figure unreliable as a stand-in for a canton as a whole. Zug city's cantonal-and-communal layer, at its current 2026 settings, is 3.5% × (78% + 52.11%) = 4.55% of net profit; a different Zug commune with its own communal multiplier produces a different number entirely, and either can move again next year when the commune resets its Steuerfuss. Zurich city's works out to 7% × (95% + 119%) = 14.98%, and carries the same commune-by-commune variation. A fixed-rate canton carries none of that variation: the rate is the rate, every commune, every year, with no Steuerfuss to reset.

None of which settles where a given company should actually be domiciled. Tax is one input, and for most operating businesses not the decisive one: proximity to banks, counsel and staff, the credibility the address carries with counterparties, and where the work is genuinely done all bear on it, and a domicile chosen purely on a rate table tends to create substance questions later. These figures are also before the federal 8.5% (identical everywhere) and before the standard self-deduction adjustment a proper year-end calculation applies, so treat them as the shape of the comparison, not a final invoice. The shape is enough to say that a canton-name-only comparison, without the specific commune and year behind it, isn't a comparison at all. It's worth resolving before incorporating, not after the Commercial Register filing.
