Swiss lump-sum taxation (also known as forfait fiscal) is a tax regime that attracts foreign newcomers to Switzerland like almost no other country in Europe. Instead of taxing worldwide income, the tax is calculated based on annual living expenses — put simply, based on rent. That sounds tempting, but it comes with a decisive restriction: anyone who is gainfully employed in Switzerland is excluded. And that affects precisely the self-employed people whom Magic Heidi supports every day with their accounting.

The legal basis is set out in the Federal Act on Direct Federal Taxation (DBG), Art. 14, supplemented by the control calculation in Art. 28 DBG. The FTA (Federal Tax Administration) has published further guidance on lump-sum taxation.

The essentials at a glance

• Lump-sum taxation = tax based on living expenses, not on actual income — basis: Art. 14 DBG.
• Requirement: first residence in Switzerland and NO Swiss gainful employment. Self-employed are therefore generally excluded.
• Calculation: typically 5× annual rent (single) or 7× annual rent (households) — varies by canton, often with a minimum of CHF 100,000.00.
• Control calculation under Art. 28 DBG: The lump-sum tax must be at least as high as the tax on Swiss income calculated at ordinary rates.
• Cantons that have abolished it: Zurich (2009), Basel-Stadt (2008), Schaffhausen (2024), Appenzell Ausserrhoden, Thurgau — by popular vote.
• Self-employed are subject to ordinary taxation — including VAT 8.1% and AHV contributions.

What is lump-sum taxation?

Swiss lump-sum taxation is a tax model that does not measure the tax on actual income but on living expenditure. The reasoning: someone who spends a lot usually has a lot at their disposal. So instead of laboriously determining worldwide interest income, dividends, and capital gains, the tax authority uses annual living expenses as the assessment basis.

The legal basis is found in Art. 14 of the Federal Act on Direct Federal Taxation (DBG). It stipulates that persons who take up tax residence or domicile in Switzerland for the first time and do not engage in any gainful employment here may have their tax assessed on a lump-sum basis. In this way, Swiss lump-sum taxation is not a tax secret for the wealthy, but a legally clearly defined instrument that mainly attracts wealthy retirees and affluent individuals from abroad.

The tax authority offsets living expenses against an assessment basis composed of several factors — rent, maintenance, staff, vehicles, holiday stays, and education. A lump sum is derived from these, which serves as the relevant income. The tax is then calculated on this basis as in an ordinary assessment — with the same tax rates and tariffs. The difference therefore lies not in the tax rate, but in the assessment basis: living expenditure instead of actual income.

For self-employed people who run a sole proprietorship in Switzerland or work as freelancers, this sounds like an attractive option. But the legal hurdle — no Swiss gainful employment — excludes precisely this group. Anyone who registers a sole proprietorship or works as a sole proprietor is engaged in gainful employment in Switzerland, and that ends lump-sum taxation. Anyone who keeps their own books for the self-employed should therefore know from the outset: the lump-sum tax is not a relevant tax advantage for the self-employed.

In short: Lump-sum taxation is a legal tax model for wealthy newcomers without Swiss gainful employment. The self-employed do not fall within its scope — they are taxed under the ordinary system.

Who can use lump-sum taxation? (Requirements)

The requirements for lump-sum taxation are narrowly defined and clearly set out in Art. 14 DBG:

1. First residence in Switzerland: You establish your tax residence or habitual abode in Switzerland for the first time. This means you have never had a Swiss tax domicile before.
2. No Swiss gainful employment: You do not engage in gainful employment in Switzerland. Not as an employee, not as a self-employed person, and not as a member of the management of a Swiss company.
3. Application to the tax authority: You submit an application for lump-sum taxation to the canton. The canton reviews and decides.

These three conditions are cumulative. If any one is missing, lump-sum taxation is excluded. So if you move to Switzerland as a German IT consultant and immediately work as a self-employed person, you have no entitlement from the outset. This also applies if you are only partially employed: any Swiss gainful employment — no matter how small — disqualifies you.

This affects many who consider coming to Switzerland as freelancers. The idea of paying taxes based on living expenses sounds tempting. But the step into self-employment automatically ends lump-sum taxation. If you are interested in tax domicile Switzerland, you should clarify early: do you want to be taxed on a lump-sum basis, or do you want to be gainfully employed?

Example: Relocation without gainful employment

Markus, a 62-year-old German retiree, moves from Munich to Weggis (canton of Lucerne) and buys an apartment there. He receives a pension from Germany and investment income from a stock portfolio, but has no gainful employment in Switzerland. He can apply for lump-sum taxation. The canton of Lucerne calculates the lump sum based on his annual rent (here an owner-occupied apartment: rental value), which is around CHF 48,000.00. The assessment basis is 5 times this rent — so around CHF 240,000.00. The tax is then calculated at the ordinary tariff on this amount, not on his actual income from German pensions and capital returns, which is significantly higher. Markus saves several thousand francs per year.

How is the lump-sum tax calculated?

The calculation of the lump-sum tax is essentially simple, but in practice it varies from canton to canton. The basic procedure:

1. Determine living expenses: The tax authority adds up annual expenditure on housing, maintenance, staff, vehicles, holidays, and education. The largest item is rent.
2. Set the assessment basis: The tax authority multiplies the rent by a factor. Typically, 5 times the annual rent applies for single persons and 7 times for households (married couples, registered partnerships, families). Some cantons apply different factors or higher minimum amounts.
3. Check the minimum amount: Many cantons set a minimum for the relevant income, often from CHF 100,000.00 to CHF 150,000.00. If the assessment basis falls below this, the minimum applies.
4. Calculate tax at the tariff: The tax is calculated on the assessment basis using the canton's and federal government's ordinary income tax tariff. This means: the same tax rate as an ordinary assessment, but on a lump-sum assessment basis.
5. Perform the control calculation: The lump-sum tax must be at least as high as the tax that would apply to Swiss source income calculated at ordinary rates. More on this in the control calculation section.

The multipliers may seem arbitrary at first glance, but they have an economic rationale: they reflect the fact that someone with high rent tends to have more wealth and income. The 5 or 7 times the rent is a rule of thumb based on empirical values.

Concrete calculation example

Maria, an Italian asset manager, moves to Lugano (canton of Ticino) and rents an apartment for CHF 4,200.00 per month — that is CHF 50,400.00 per year. She has no Swiss gainful employment and lives off dividends and rental income from Italy.

• Annual rent: CHF 50,400.00
• Factor for single persons: 5 → Assessment basis: CHF 252,000.00
• Cantonal minimum (Ticino): around CHF 100,000.00 → does not apply here, as the assessment basis is higher.
• Tax at ordinary tariff on CHF 252,000.00: This results in a combined federal and cantonal tax of approximately CHF 35,000.00 to CHF 45,000.00 depending on the exact configuration.

If Maria had been required to pay ordinary tax on her actual worldwide income of around CHF 900,000.00, the tax would have been significantly higher — roughly estimated at three to four times as much. Lump-sum taxation thus gives her a noticeable relief.

The exact factors and minimum amounts vary from canton to canton. The canton of Geneva, for example, sets a minimum of around CHF 150,000.00, the canton of Vaud slightly less. For a precise estimate, you should contact the cantonal tax administration or hire a fiduciary.

Control calculation under Art. 28 DBG

Swiss lump-sum taxation is not a blank check, but has a built-in lower limit: the control calculation under Art. 28 DBG. It ensures that the lump-sum tax is at least as high as the tax that would apply to Swiss income calculated at ordinary rates.

The control calculation works as follows:

• The tax authority takes the taxpayer's Swiss income — i.e., income from Swiss sources such as real estate, Swiss dividends, Swiss interest, Swiss pensions — and calculates the tax on it using the ordinary method.
• It then compares the lump-sum tax with this ordinary tax on Swiss income.
• If the lump-sum tax is higher, it applies — the taxpayer benefits.
• If the ordinary tax on Swiss income is higher, this amount is charged. The lump-sum tax is thus raised to this maximum amount.

This control calculation prevents someone with significant Swiss income from pushing the tax down through a low lump sum. So if, for example, you own Swiss real estate and earn high rental income from it, you cannot use lump-sum taxation to avoid this income — the control calculation catches up with you.

For most pure wealth immigrants who have no Swiss source income, the control calculation hardly matters, since the lump-sum tax exceeds the tax on Swiss income (close to zero). But if you have Swiss income, you should factor the control calculation into your considerations.

The control calculation is an important safeguard that justifies lump-sum taxation in public debate. It prevents the model from being used purely as a tax-saving tool for Swiss income. The FTA (Federal Tax Administration) publishes further guidance on the concrete calculation.

Cantonal differences: Where lump-sum taxation applies

Swiss lump-sum taxation is not available in all cantons. Several cantons have abolished the model by popular vote — usually after heated political debates. The canton decides for itself whether to offer lump-sum taxation and, if so, on what terms.

Cantons that have abolished lump-sum taxation

• Zurich (2009): First canton to abolish lump-sum taxation by popular initiative. Around 4,000 taxpayers were affected, who were subsequently assessed under ordinary rules.
• Basel-Stadt (2008): Abolished by cantonal council resolution and popular vote.
• Appenzell Ausserrhoden: Abolished by Landsgemeinde, a strong democratic signal.
• Schaffhausen (2024): Most recent abolition, by popular vote. The canton is small, but the signal is clear.
• Thurgau: Abolished by popular vote, also implemented in recent years.

In these cantons, lump-sum taxation no longer exists. Anyone living there is taxed on their worldwide income under ordinary rules — regardless of whether they have Swiss gainful employment or not.

Cantons that have retained the model

In most other cantons, lump-sum taxation continues — including Geneva, Vaud, Valais, Ticino, Lucerne, Bern, Graubünden and others. The conditions vary:

• Minimum amounts: Some cantons require minimum amounts from CHF 100,000.00 to CHF 150,000.00. Geneva has one of the highest rates at around CHF 150,000.00.
• Factors: The rent multiplication factors range from 5 (single) to 7 (households), and occasionally other values.
• Concessions: Some cantons grant discounts if the taxpayer makes significant local investments or lives locally.

The political debate over lump-sum taxation has never fully subsided in Switzerland. Critics see the model as a tax gift to the wealthy; supporters emphasize that it attracts affluent foreigners who consume locally and pay taxes they otherwise would not have paid in Switzerland at all. For the self-employed, however, this debate hardly matters, since they do not fall within the scope anyway.

Why the self-employed cannot use lump-sum taxation

Here is the point that is decisive for the Magic Heidi community: the self-employed are excluded from lump-sum taxation because they are gainfully employed in Switzerland.

This is not a matter of authority discretion, but a mandatory requirement under Art. 14 DBG. Anyone who engages in gainful employment in Switzerland — whether as an employee, a self-employed person, a managing partner, or a member of a foundation board — has no entitlement to lump-sum taxation. Any Swiss gainful employment disqualifies, regardless of scope or income.

What does this mean concretely for the self-employed?

• Sole proprietorship: Anyone who registers a sole proprietorship in the commercial register and is self-employed is engaged in Swiss gainful employment — lump-sum taxation excluded.
• GmbH shareholder: Anyone who works as a shareholder of a GmbH and receives a salary from it is gainfully employed — lump-sum taxation excluded.
• Freelancer with clients: Anyone who works as a freelancer for Swiss clients is generally classified as self-employed and therefore gainfully employed — lump-sum taxation excluded.
• Part-time work: Even a very small Swiss gainful employment disqualifies — there is no de minimis threshold.

This means: if you come to Switzerland as a foreign freelancer and work here, you will be taxed under ordinary rules. Swiss lump-sum taxation is not a tax model for the self-employed — it is a model for wealthy individuals who live in Switzerland but do not work here. Anyone who keeps books for the self-employed should know from the outset that ordinary taxation applies.

Why this restriction?

The idea behind lump-sum taxation is that someone who lives here without working here should pay taxes to Switzerland based on their living expenditure. But someone who works here has a local income that can be taxed under ordinary rules — so a lump sum based on living expenses makes no sense. The system wants to clearly capture and tax gainful employment in order to protect Switzerland's tax base.

For the self-employed, this means: no loophole, no lump sum, no special treatment. You are treated like any other gainfully employed taxpayer. That is fair, even if for some it sounds like a missed tax advantage.

In short: The self-employed engage in Swiss gainful employment and are therefore excluded from lump-sum taxation. Ordinary taxation applies automatically.

Ordinary taxation for the self-employed: What applies instead

When lump-sum taxation does not apply, ordinary taxation applies — and for the self-employed, this is not a disadvantage but a clear, transparent system. Here is an overview of the key points the self-employed should know:

Income tax on actual profit

The self-employed pay tax on their business profit as income. Profit is revenue minus business-related expenses. These include material costs, office rent, IT expenses, consulting, insurance, travel, training, and much more. If you keep clean books, you can deduct a lot and reduce the tax base — legally and transparently.

Income tax is calculated according to the progressive tariff of the federal government and the canton. Those who earn more pay more; those who earn little pay little. That is fair, but it also means that a higher profit noticeably increases the tax burden.

VAT: 8.1% on supplies and services

The self-employed who generate domestic revenue of CHF 100,000.00 or more per year are VAT-liable and must show 8.1% VAT on their invoices. VAT is not a tax burden for the entrepreneur but a pass-through item — you collect it from the customer and report it to the FTA. What you spend on VAT (input tax), you can deduct.

If you are VAT-liable, you should keep clean books. Software like Magic Heidi helps: you issue QR-bills with correct VAT, log income and expenses, and report VAT periodically — for a fraction of what bexio costs. Magic Heidi is available from CHF 25.00 per month; bexio costs around CHF 52.00 per month. For solo self-employed, a clear difference that adds up to CHF 300.00 or more over a year.

AHV: Contributions on profit

The self-employed pay AHV contributions — AHV is Swiss social security — on business profit. The rate is regularly around 10% of profit up to the maximum AHV contribution ceiling. Those who earn little pay a reduced rate. AHV is an insurance, not a tax in the strict sense, but for the self-employed it is a significant burden that should be planned for in financial forecasting.

Here is an example: a self-employed person with CHF 80,000.00 profit pays around CHF 8,000.00 AHV per year. Someone with CHF 200,000.00 profit pays the maximum rate and comes in at around CHF 24,000.00. These contributions are not optional — the compensation office contacts you after the first tax return.

Final assessment and provisional payments

In the first year, the self-employed often pay no provisional installments but only the final assessment after the assessment notice. From the second year onward, the canton requests provisional payments, usually based on the previous year's tax. Anyone who plans with a provisional tax bill can better gauge the provisional payments.

Ordinary taxation for the self-employed is therefore a complete, clear system: pay tax on profits, remit VAT, pay AHV, make provisional payments. No lump sum, but also no uncertainty about the requirements.

Lump-sum taxation vs. ordinary taxation compared

Here is a comparison of the two models — helpful for understanding why lump-sum taxation is out of reach for the self-employed anyway:

The table shows: anyone who is gainfully employed in Switzerland has only ordinary taxation as a realistic option. Lump-sum taxation is a special case for wealth immigrants without Swiss employment.

Example: Two paths, two tax burdens

Two Swiss taxpayers, same place of residence (Lugano), same actual income of CHF 400,000.00:

• Person A — Lump-sum taxation: Moves from Italy, does not work in Switzerland. Annual rent CHF 60,000.00. Assessment basis 5× = CHF 300,000.00. Tax at tariff: around CHF 45,000.00.
• Person B — Ordinary taxation: Is self-employed, runs a sole proprietorship in Switzerland. Profit CHF 400,000.00. Tax at tariff: around CHF 85,000.00, plus AHV approx. CHF 24,000.00, plus VAT administration work.

Person A pays around CHF 45,000.00, Person B around CHF 109,000.00 — a difference of around CHF 64,000.00. However, Person B has the ability to deduct expenses, which reduces the tax burden. Anyone who properly accounts for their office, car, and training can significantly reduce profit and therefore tax. This is the lever for the self-employed — not in lump-sum taxation, but in clean bookkeeping.

Example: A self-employed person who thought she could use the lump sum

Lena, 34, a German graphic designer, moves from Berlin to Bern. She reads online about lump-sum taxation and hopes not to have to fully tax her income of around CHF 120,000.00 per year from freelance work. She rents an apartment for CHF 2,400.00 per month and calculates: 5 × CHF 28,800.00 = CHF 144,000.00. That sounds attractive.

But Lena registers her sole proprietorship in the commercial register and works for Swiss clients. The tax authority denies lump-sum taxation — she is engaged in Swiss gainful employment. Lena is assessed under ordinary rules. On CHF 120,000.00 profit (after deducting business expenses), she pays around CHF 22,000.00 income tax plus around CHF 12,000.00 AHV. Had she been able to claim lump-sum taxation, it would have been around CHF 18,000.00 tax without AHV. The difference is moderate — but the lump sum was never available to her.

The lesson: clarify early whether the requirements apply. If you work in Switzerland, skip the application. Ordinary taxation is not a nightmare but a transparent system that is well manageable with clean bookkeeping. If you are looking for a bexio alternative tailored to Swiss solo self-employed, Magic Heidi provides the right tools — significantly cheaper than the competition.

Conclusion: Swiss lump-sum taxation is not a model for the self-employed

Swiss lump-sum taxation is a successful model for wealthy newcomers without Swiss gainful employment. It lowers the tax burden by linking it to living expenditure rather than actual income. The control calculation under Art. 28 DBG ensures that Switzerland does not come up short. The cantonal abolitions in Zurich, Basel-Stadt, Schaffhausen, Appenzell Ausserrhoden, and Thurgau show that the model is politically controversial — but in most cantons it remains an instrument that attracts foreign wealth.

For the self-employed, however, the model does not apply. Anyone who is gainfully employed in Switzerland — as a sole proprietorship, GmbH shareholder, or freelancer — is excluded from lump-sum taxation. This is not a matter of discretion but a mandatory requirement under Art. 14 DBG. Ordinary taxation is the only relevant system for the self-employed: pay tax on profits, remit VAT, pay AHV, make provisional payments.

If you are self-employed in Switzerland, rely on clean bookkeeping. Proper accounting of income and expenses reduces the tax burden legally and transparently. With Magic Heidi, you have software tailored to Swiss solo self-employed: QR-bills, VAT accounting, income statement, provisional planning — all from a single source. From CHF 25.00 per month, well below bexio at around CHF 52.00 per month.

If you want to examine lump-sum taxation for yourself, you should hire a fiduciary or contact the cantonal tax administration. The FTA (Federal Tax Administration) and the cantonal offices provide non-binding advice. For the self-employed: taxed under ordinary rules, booked cleanly, taxed fairly.
