Switzerland income tax calculator

The federal tax is the small half

Direct federal tax is capped at 11.5% by the constitution. That is the whole ceiling, for any income, forever — article 128 of the Federal Constitution sets the maximum rate and parliament cannot exceed it without a referendum.

Which means the federal layer cannot be what makes Switzerland expensive or cheap. On CHF 100,000 of taxable income a single person pays CHF 2,684 in federal tax, an effective rate of 2.68%. Nobody moves canton over that.

Cantonal and communal income tax is the rest, and it is commonly two to three times the federal amount. Each of the 26 cantons legislates its own tariff, and each commune within it applies its own multiplier to that tariff, so the total varies from one village to the next.

That is the whole story of Swiss tax competition. Zug and Schwyz against Geneva and Vaud is a cantonal argument; the federal scale on this page is identical in all of them.

This calculator computes the federal layer exactly, because that is the layer that has a single national answer. It does not estimate the cantonal one, because a national average would be wrong everywhere and a specific canton would need the commune too.

A tariff written in francs, not in percentages

Article 36 of the federal direct tax act does not print rates. It prints sentences of the form "for CHF 33,200 of income, CHF 138.60, and for each further CHF 100 of income, CHF 0.88 more".

So the scale is a list of anchor points with a franc amount attached to each, plus a franc amount per additional hundred. Converting that to percentages is something the reader does, not something the statute does.

The single tariff has ten anchors, from CHF 15,200 where tax begins to CHF 185,100 where the CHF 13.20-per-hundred step starts. The married tariff has fourteen, running from CHF 29,700 to CHF 152,400 in much finer steps.

Checking those anchors turned up something worth publishing. All fourteen married anchors reproduce exactly, to the centime, from the anchor before plus the per-hundred amount. Three of the ten single anchors do not: CHF 43,500, CHF 76,200 and CHF 82,100 are each published a centime or four below the strict arithmetic.

That is rounding in the statute rather than an error anywhere, and this engine uses the published anchors — which is literally what the law says to do. The test asserts the deviations exist, are always downward, and never exceed four centimes.

The 11.5% ceiling, and how it appears in the table

The constitutional maximum shows up in article 36 in a way that is easy to miss. After the last incremental anchor, the single tariff simply states: for CHF 794,000 of income, CHF 91,310, and CHF 11.50 for each further CHF 100.

CHF 794,000 × 11.5% is exactly CHF 91,310. The table is not describing a top band — it is describing the point at which the average rate reaches the ceiling, after which the whole income is taxed at 11.5% flat.

For the married tariff the same thing happens at CHF 941,400, where CHF 108,261 is exactly 11.5% of the income.

The consequence is that above those points the marginal rate falls to meet the average rate rather than exceeding it, which is the opposite of how every other scale on this site behaves. A Swiss federal marginal rate of CHF 13.20 per hundred — 13.2% — exists in the middle of the table and not at the top.

It is a genuinely unusual constitutional constraint: most countries limit tax through politics, and Switzerland limits it through a number in the constitution that a popular vote would have to change.

A second tariff, not a splitting factor

Married couples are assessed jointly in Switzerland — their incomes are added — and the federal system compensates with a separate, gentler tariff rather than by dividing income the way Germany and France do.

The married tariff starts later, at CHF 29,700 against CHF 15,200, and climbs in much finer steps: fourteen anchors instead of ten, moving by one franc per hundred at a time from CHF 1.00 up to CHF 13.00.

It reaches the ceiling later too, at CHF 941,400 of income rather than CHF 794,000, which means the married tariff is more generous all the way up rather than only at the bottom.

The same tariff applies to single parents and to anyone living with and mainly supporting children or dependants — article 36 paragraph 2bis — and the tax so computed is then reduced by CHF 263 for each of them.

Even so, joint assessment produces the classic marriage penalty for two similar incomes, which is why cantonal systems apply their own corrections and why the question has been to a national referendum more than once. None of those cantonal corrections is in this figure.

The federal tariff at four incomes

Taxable income after deductions, federal layer only. The second figure is the same income assessed on the married tariff.

On CHF 60,000: CHF 671 single, an effective rate of 1.12% — or CHF 369 married, 0.61%.

On CHF 100,000: CHF 2,684 single, an effective rate of 2.68% — or CHF 1,816 married, 1.82%.

On CHF 200,000: CHF 12,903 single, an effective rate of 6.45% — or CHF 11,880 married, 5.94%.

On CHF 500,000: CHF 52,503 single, an effective rate of 10.50% — or CHF 50,880 married, 10.18%.

Multiply any of those by three or four for a rough sense of the total including cantonal and communal tax, and the reason nobody discusses Swiss tax in terms of the federal scale becomes obvious.

How Switzerland compares with the rest of this site

Against Canada, the structure rhymes and the proportions are reversed. Both stack a sub-national income tax on a federal one; in Canada the federal layer is the larger of the two, in Switzerland it is much the smaller.

Against Germany, the neighbour, the contrast is total. Germany writes its tax as a continuous formula with a 45% top rate; Switzerland writes a franc table with an 11.5% constitutional ceiling and pushes all the progressivity down to the canton.

Against the United States, the comparison is the most useful one available. A US taxpayer faces federal plus state plus sometimes local; a Swiss taxpayer faces federal plus cantonal plus communal. Both are three-layer systems where the national headline rate tells you very little.

Against Hong Kong, the 11.5% federal ceiling and the 16% Hong Kong ceiling look similar and mean opposite things: Hong Kong's is the whole tax, Switzerland's is a third of it.

What Switzerland has that nothing else here does is a rate limit written into the constitution. Every other ceiling on this site is a policy choice that a budget can change.

Four ways a Swiss estimate goes wrong

Treating the federal figure as the Swiss tax. It is typically a quarter to a third of the total. Any comparison built on it alone puts Switzerland in the wrong league entirely.

Averaging the cantons. There is no meaningful Swiss average, because the communal multiplier moves the answer within a canton almost as much as the canton moves it within Switzerland.

Using the single tariff for a household with children. A single parent uses the married tariff under paragraph 2bis, which is materially gentler.

Reading 11.5% as a top band. It is a ceiling on the whole bill. Above CHF 794,000 the average rate and the marginal rate are both 11.5%, and the highest marginal rate in the table — 13.2% — sits below it, not above.

Why there is no Swiss average

Twenty-six cantons legislate their own income tax scale. Within each, every commune sets a multiplier — the Steuerfuss or coefficient — applied to the cantonal base tariff. The canton applies a multiplier of its own on top.

So a Swiss tax bill is federal, plus cantonal base tariff × cantonal multiplier, plus the same base tariff × communal multiplier. Two of the three moving parts are local, and the communal one changes at the boundary of a village.

The spread is not marginal. Between the lightest and heaviest cantons the total burden on a professional salary can differ by a factor approaching two, and that gap is the engine of Swiss internal tax competition — the reason companies and individuals relocate between cantons rather than between countries.

The Federal Tax Administration publishes comparative burden statistics precisely because no single figure exists. Any calculator quoting one Swiss rate has either picked a canton without saying so or averaged something that nobody actually pays.

This page does neither. It computes the layer that is identical everywhere in Switzerland and states plainly that the larger part depends on an address.

Withholding at source, and who never files a return

Most foreign nationals working in Switzerland without a settlement permit are taxed at source. The employer withholds under a cantonal scale that already combines federal, cantonal and communal tax into a single rate.

For those taxpayers the federal figure on this page is not the relevant number in isolation: it is already inside their withholding rate, mixed with two layers this page does not model.

Above an income threshold, or on request, a taxpayer under withholding can be assessed in the ordinary way, which lets them claim deductions the withholding scale only approximates — pillar 3a contributions, actual professional expenses, childcare costs, debt interest.

Whether that is worth doing depends on the deductions available and on the canton, and it is a decision with a deadline: the request has to be made in the year following.

Swiss nationals and permit C holders file an ordinary return regardless, which is why two colleagues doing the same job for the same salary can have completely different relationships with the tax system.

The deductions that come before the tariff

The tariff on this page runs on taxable income, and Swiss taxable income is a long way below gross salary. The deductions are where much of the planning happens.

Pillar 3a — restricted private pension saving — is fully deductible up to an annual cap that differs for employees with an occupational pension and for those without. It is the single most-used deduction in the country.

Pillar 2 buy-ins are deductible in the year they are made, which makes them a substantial and legitimate tool for smoothing a high-income year, subject to lock-up rules on subsequent withdrawal.

Beyond those: professional expenses including commuting and meals, insurance premiums within caps, childcare costs, debt interest, and deductions for a married couple and for each child. Cantonal amounts differ from federal ones for most of these.

None of them is applied here. Someone entering a gross salary rather than a computed taxable income will get a federal figure that is too high, on top of a total that is already missing its larger half.

AHV and the second pillar, which are not tax

Swiss social insurance is deducted from salary before anything on this page applies, and it is substantial.

AHV/IV/EO — old age, disability and loss of earnings insurance — takes a flat percentage of the whole salary with no ceiling at all, matched by the employer. It is one of very few uncapped social contributions anywhere, which makes it mildly progressive at the top rather than regressive.

Unemployment insurance is charged up to a ceiling, with a reduced solidarity rate above it. Occupational pension contributions under the second pillar depend on age and rise in steps through a career, and are shared with the employer.

Accident insurance for non-occupational accidents is typically borne by the employee. Health insurance is not deducted from salary at all: it is a private premium the individual pays directly, which is one of the largest differences between a Swiss payslip and a German or French one.

None of that is in the figure here, and second-pillar contributions are also deductible from taxable income — so including them properly would reduce both the take-home and the tax.

What Switzerland does not tax, and the one thing it does

Private capital gains on movable assets are not taxed in Switzerland for an ordinary investor. Selling shares at a profit produces no income tax charge, which puts Switzerland alongside Singapore, Hong Kong and New Zealand rather than alongside its European neighbours.

Dividends and interest are taxed as income, with a partial relief for qualifying participations. Gains on real property are taxed, but by a separate cantonal property gains tax rather than through the income tax scale.

Against that, Switzerland taxes something almost nobody else does: imputed rental value. An owner-occupier is taxed on the notional rent their own home could command, with mortgage interest and maintenance deductible against it. The Eigenmietwert is a long-running political argument and it materially changes the arithmetic of owning versus renting.

Wealth tax is also charged at cantonal level on net assets, at low rates but on the whole balance sheet. It is one of the few remaining wealth taxes in Europe and it is entirely outside the income tax computed here.

So the 11.5% federal ceiling should be read with all of that in mind: a low income tax rate on a base that excludes capital gains and includes imputed rent, alongside a wealth tax and a large cantonal layer.

Questions

How much federal tax do I pay on CHF 100,000 in Switzerland?

CHF 2,684 of direct federal tax as a single person — an effective rate of 2.68%. Cantonal and communal tax is charged on top and is commonly two to three times that, so the total on this income is realistically in the region of CHF 8,053 to CHF 10,737 depending on where you live.

What is the top rate of Swiss federal income tax?

11.5%, and it is a ceiling rather than a band. Article 128 of the Federal Constitution caps direct federal tax on individuals at that rate, so above CHF 794,000 of income for a single person the whole income is taxed at 11.5% flat — the marginal rate falls to meet the average rather than exceeding it.

Why does this not include cantonal tax?

Because there is no single answer to give. Each of the 26 cantons sets its own tariff and each commune applies its own multiplier, so two people on identical incomes a few kilometres apart pay materially different tax. A national average would be wrong everywhere, so this page computes the one layer that is identical across Switzerland and says plainly that it is not the whole bill.

When does Swiss federal tax start?

At CHF 15,200 of taxable income for a single person and CHF 29,700 for a married couple, and amounts below CHF 25 are not collected at all. Cantonal thresholds are set separately and are generally lower, so someone paying no federal tax may still owe cantonal and communal tax.

How are married couples taxed in Switzerland?

Jointly, with their incomes added, and compensated by a separate and gentler tariff rather than by splitting. The married tariff starts at CHF 29,700, climbs in fourteen finer steps, and reaches the 11.5% ceiling at CHF 941,400 instead of CHF 794,000. A single parent living with dependent children uses the same tariff.

What do children reduce?

CHF 263 off the federal tax for each child or dependent person, under article 36 paragraph 2bis, and any dependent child also moves the household onto the married tariff. Separate deductions from taxable income exist for children and childcare and are not applied here.

Does the federal tariff use percentages?

No, and that is worth knowing before comparing it to anything. Article 36 states amounts in francs — "for CHF 33,200 of income, CHF 138.60, and for each further CHF 100 of income, CHF 0.88 more". The per-hundred amounts are numerically the same as percentages, but the anchors are fixed franc figures and three of the ten in the single tariff are published a few centimes below the strict arithmetic.
