What leaving a church actually changes on your tax bill
Leaving a recognised church in Switzerland also ends the obligation to pay church tax. How much that actually saves depends heavily on where you live — church-tax rates are set by canton, and sometimes even by parish. This piece compares five municipalities in five cantons at the same income, showing exactly what belonging to a church costs on top of the ordinary bill. It takes no position on whether leaving is a good idea — that is a personal decision that goes well beyond francs.
The figures: with and without a confession
Every figure below comes from Zügle's tax cache for tax year 2026, for a single person with no children on a gross income of CHF 130'000. The "no confession" column is the ESTV `Confession: none` value — exactly what the bill looks like after a formal withdrawal.
| Municipality (canton) | No confession | With confession | Difference |
|---|---|---|---|
| Zürich (ZH) | CHF 18'647 | CHF 19'355 (reformed or Roman Catholic) | CHF 19'355 − CHF 18'647 = CHF 708 / yr |
| Schwyz (SZ) | CHF 12'878 | CHF 13'736 (Roman Catholic) | CHF 13'736 − CHF 12'878 = CHF 858 / yr |
| Zug (ZG) | CHF 9'384 | CHF 9'655 (Roman Catholic) | CHF 9'655 − CHF 9'384 = CHF 271 / yr |
| Luzern (LU) | CHF 17'094 | CHF 18'170 (Roman Catholic) | CHF 18'170 − CHF 17'094 = CHF 1'076 / yr |
| Basel (BS) | CHF 22'080 | CHF 23'568 (reformed) | CHF 23'568 − CHF 22'080 = CHF 1'488 / yr |
In Zürich the reformed and the Roman Catholic rate come out identically at this income (both CHF 19'355). That follows from how Zürich's own tax-fuss (multiplier) system works out for this municipality, and it will not hold everywhere. The absolute franc amount varies more: CHF 271 in Zug, CHF 1'488 in Basel, at the identical income and marital status. The size of the church-tax difference does not simply follow how expensive the municipality is overall: Zürich has the second-highest total tax on this list but the second-smallest church-tax gap (CHF 708), while Schwyz, far cheaper overall, still has a larger one at CHF 858.
Where the difference comes from
The "difference" column is a subtraction of two rows from the same tax cache, for the same income, the same marital status, the same municipality. That gets close to what a formal withdrawal would change on this specific bill, provided every other factor (income, deductions, place of residence) stays the same. It is not a forecast for your own bill: at a different income, a different marital status, or with children, both the church-tax share and the overall tax shift move, often not proportionally.
Church tax also applies to companies
In several Swiss cantons, legal entities — companies — pay a church-tax surcharge as well, where they belong to a recognised national church or the canton applies it as a flat levy on all firms. The Federal Tax Administration (ESTV) publishes cantonal church-tax rates for legal entities regularly in its "Steuermäppchen" (estv.admin.ch), where the rate, and whether it applies at all, can be looked up canton by canton. For an individual thinking about leaving, this is mostly a side fact. It does show that church tax in Switzerland belongs to the wider cantonal tax system and is not confined to private individuals.
The withdrawal: federal law and cantonal rules
Federal law settles one thing clearly: under the Swiss Civil Code (ZGB) Art. 303 para. 3 (fedlex.admin.ch), a child reaches religious majority at the completed age of 16 and from then on decides independently about confession, the practice of religion, and entering or leaving a religious community. Parental authority over this ends at that point.
What varies by canton and by parish, on the other hand, is the exact form the withdrawal declaration must take, whether an officially certified signature is required, how long it takes to become effective, and whether a fee applies. These details also change from time to time. For the concrete procedure, your own parish office or the cantonal confessional register is the reliable source; this overview cannot replace it.
Limits of this overview
- Only one confession per municipality is shown here, not both where both exist.
Where both are known (Zürich), they happen to match here — that need not hold everywhere.
- Only one income (CHF 130'000) and one marital status (single, no children) are
computed. For a married couple with children, both the overall bill and the church-tax share shift, sometimes quite differently from here.
- Membership in a church means more than a tax line for many people. This overview
gives you the number only, no judgement.
- All tax figures are for tax year 2026; in another year the tax-fuss (multiplier)
values change, and so do these differences.
- Nothing here is tax or legal advice — it is an evaluation of public data for one
specific example.
Run your own figures
The most accurate way to know your own church-tax difference is with your own income and your own municipality — not the example values above.
