Lump-sum or ordinary taxation in Switzerland?

Lump-sum taxation usually suits people with large foreign income or assets and a lifestyle that sits comfortably above the minimum bases. Ordinary taxation tends to win when your actual income is modest compared with those minimums, when most of your income is Swiss-source anyway, when you or your spouse want to work in Switzerland, or when inheritance and family plans point that way. The switch from lump sum to ordinary is generally one-way, so it deserves care.

Key facts (as of September 2026)

How the two regimes differ

Ordinary taxation is what most Swiss residents have. You declare your worldwide income each year and pay federal, cantonal and communal income tax on it, plus a cantonal wealth tax on your net worldwide assets. There is no federal wealth tax. Wealth tax is mostly progressive, but Lucerne, Uri, Schwyz, Obwalden, Nidwalden, Glarus, Appenzell Innerrhoden, St. Gallen and Thurgau use flat rates. Gains on private movable assets, such as shares and art, are tax-free; gains on real estate fall under a separate cantonal tax.

Lump-sum taxation replaces the income calculation with a base set by your worldwide living costs, never below the highest of a federal minimum (CHF 435,000 in 2026), a cantonal minimum, seven times your rent and a control calculation on certain Swiss-source income. Wealth is covered by each canton's own method. Our overview of Swiss lump-sum taxation explains the conditions in full.

When ordinary taxation can win

Your real income is modest compared with the minimum

The lump sum starts from a high floor. If your actual worldwide income is well below what you would be taxed on under the lump sum, ordinary taxation may simply produce a lower bill. This often applies to people living mainly on a moderate pension or on capital they are drawing down.

Most of your income is Swiss anyway

The control calculation makes sure the lump-sum tax is at least the ordinary tax on Swiss real estate, Swiss movables, capital invested in Switzerland, Swiss-source pensions and treaty-relieved foreign income. If those items make up most of your income, the control calculation may set your tax, and the lump sum offers little. See how the lump-sum tax is calculated for the detail.

You or your spouse want to work here

Any gainful activity in Switzerland, even a side occupation or a board seat paid from abroad, ends the lump sum. It also ends it for your spouse, for the whole tax period. If either of you expects to work, take a board role or run a business from Switzerland, ordinary taxation is the realistic basis to plan on.

Swiss citizenship is in view

Swiss nationals cannot be taxed on a lump sum, and naturalisation ends it for the whole tax period in which it happens. Families who expect to seek citizenship, or who include a Swiss spouse, should plan on ordinary taxation.

You rely on treaty relief

Lump-sum taxpayers can claim treaty relief, but that income then counts in the control calculation, and under the treaties with Belgium, Germany, Italy, Norway, Canada, Austria and the United States all income from that country must be taxed as under ordinary taxation. Lump-sum taxpayers also generally cannot use the flat-rate foreign tax credit. If your income is concentrated in those countries, the advantage can narrow. See modified lump sum and tax treaties.

Inheritance planning, especially in Geneva

Inheritance and gift tax is cantonal. Spouses are exempt in all cantons and direct descendants in most. Geneva, however, removes the spouse and descendant exemption if the deceased or donor was lump-sum taxed in one of the last three final assessments before the death or gift. For a family living in Geneva, that can outweigh years of income-tax savings. Our guide on inheritance and gift tax covers the cantonal picture.

You want to live in Zurich or Basel

Zurich, Schaffhausen, Appenzell Ausserrhoden and Basel-Stadt have abolished the lump sum, and Basel-Landschaft allows it only for the arrival year. If one of these is where your family wants to be, ordinary taxation is the regime. Zurich does grant non-EU nationals residence on fiscal grounds, but its directive sets the bar at around CHF 1 million of tax a year, confirmed by the tax authority, together with close ties to the canton and the move of the whole family. See our Zurich canton page.

When the lump sum tends to fit

The lump sum tends to suit families who:

• have substantial foreign income or wealth compared with their living costs;
• hold most of their assets outside Switzerland and do not need treaty relief from the seven modified-lump-sum countries;
• do not plan to work in Switzerland, and neither does a spouse;
• value a predictable figure agreed in advance with the canton;
• are drawn to a canton that offers it.

For non-EU nationals, the lump sum is also closely tied to the permit route on fiscal grounds, which some cantons link directly to the tax agreement. The tax agreement itself is not a permit: the canton decides at its discretion and SEM must approve.

Things that do not change with the regime

Some costs follow you either way. As a non-employed resident, you pay Swiss social-security (AHV/AVS) contributions until age 65, based on your wealth plus 20 times your annual pension income: from a minimum of CHF 530 to a maximum of CHF 26,500 a year in 2026. Basic health insurance must be taken out within three months of registering with your commune. And Swiss withholding tax of 35% on Swiss dividends and interest can be reclaimed by Swiss residents who declare the income.

The one-way door

Circular 44 is clear that once you give up the lump sum for ordinary taxation, you generally cannot return to it. That makes the first choice important and the timing of any later switch even more so. People usually move to ordinary taxation when their situation changes: a job, a Swiss passport, a large Swiss investment or an inheritance plan.

A sensible approach is to model both regimes on your real figures before you move, and to look again whenever your circumstances change.

Questions to ask before you decide

1. What is my actual worldwide income compared with the likely lump-sum base?
2. How much of it is Swiss-source, or from a modified-lump-sum treaty country?
3. Will either of us work, sit on a board or seek Swiss citizenship?
4. Which canton do we want to live in, and what does it do with wealth and inheritance?
5. How might our situation change in five or ten years?

How we help

We model lump-sum and ordinary taxation side by side on your own figures, in the cantons you are considering, and look at inheritance and family plans alongside the annual tax. We then help you secure the chosen route in a ruling. Start with the eligibility check for an indicative view.
