1. Major Domestic Reform Individual Taxation Reform

A historic popular referendum On 8 March 2026, Swiss voters approved through an nationwide referendum the new Federal Act on Individual Taxation.

At stake here is one of the main points of friction between the Swiss fiscal system and an increasingly liberal approach in that country: the tax assessment of married individuals. Decoupling of taxation Currently married couples in Switzerland were jointly assessed: that is, their income, whether individually derived or not, accumulated and was assessed on the couple as a whole. In doing so, as the Swiss tax table is progressive, tax advice for expats dual-income couples find themselves at a higher level of taxation for an equivalent gross income as compared to two non married persons having the exact same gross income. Following the aforementioned decision, this is henceforth replaced by an individual approach, at both federal and cantonal level.

The main impacts are thus as follows: Individual income declarations: spouses should independently declare their earned incomes.

Separate assessment of assets and income: revenues and assets, real property and investments will be apportioned and declared strictly in relation to actual civil ownership rights of either spouse. New flexibility for the Lump-Sum tax framework: foreigners benefiting of Lump-sum taxation will find it more appealing. Both partners will be assessed on an individual basis, allowing one spouse to benefit from Lump-sum taxation while the other may choose to be subject to the normal Swiss taxation on earned income.

Timeline The Federal Act lays the principles; actual implementation is being processed cantonal by canton in Switzerland, the country has three level (federal, cantonal, local) tax systems. The entire transposition is planned to be completed not later than 2032.

3. New Developments for Swiss Businesses

The dynamic digital environment and the revised indirect tax environment will require Swiss businesses-both corporations and self-employed-to stay updated:

3.1 Corporate Income and Capital Tax Trends

The cantons continue refining their corporate rates, focusing on maintaining attractiveness, while complying with international standards for transparency.

While basic corporate rates are generally low, companies will still need to perform complex calculations to account for deductions, patent boxes, andR&D grants applied locally.

The Standard Rate stands at 8.1%A Reduced Rate is applicable at 2.6%(applies to food items, medications, books, newspapers, magazines and basic necessities)A Special Accommodation Rate is set at 3.8%A stringent regulation is already applicable whereby online marketplaces, which supply goods and services from abroad to consumers in Switzerland, will be considered as acting under “deemed supplier” role.

4. Swiss Global Minimum Tax Updates

The implementation of the OECD/G20 Pillar Two project, which has affected major corporations globally, will have a bearing on Swiss companies as well to protect Switzerland’s tax base and revenue.4.1 Pillar Two and the 15% StandardUnder Pillar Two of the OECD framework, multinational enterprises (MNEs), that have group annual revenues totaling over 750 million, will now besubjected to 15% as the minimum effective tax rate in every country where they operate.

How Top-Up Taxes Function

To implement this minimum, Switzerland employs three synergistic mechanisms: – Qualified Domestic Minimum Top-Up Tax (QDMTT) – which permits Switzerland tolevy top-up tax locally on Swiss entitiesbefore other jurisdictions may do so;

– Income Inclusion Rule (IIR) – which capturesundertaxed profits from foreigntop-level foreign subs diaries thatare owned by Swiss parent;and

– Undertaxed Profits Rule (UTPR) – which acts as aninternational backstoppingmechanism for any collectedtop-up amounts.

5. Cross-Border Tax Changes

As international mobility rises, cross-border tax agreements and reporting standards remain top priorities for tax authorities.

Automatic Exchange of Information (AEOI)

Switzerland’s network for the Automatic Exchange of Information encompasses over 100 partner states. Financial accounts held abroad by Swiss residents—including bank accounts, investment portfolios, and crypto-asset holdings—are systematically reported back to the Federal Tax Administration (FTA).

Switzerland-EU Tax Cooperation

Cross-border commuters: For the above-mentioned cross-border workers (frontaliers – employees working in CH but residing in France, Germany or Italy), recent double tax treaties make remote working specific: They establish concrete limits for how much you are able to work in another country, avoiding an unintended tax burden in one’s home state.

6. A Digitalised Swiss Tax Authority

On the paper trail front: Paper tax declarations are increasingly disappearing from every Swiss canton. Afully digitalised Swiss tax system would mean speed, however taxpayers should aim at storing documents systematically digitally.

Mandatory digital tax filing: Through centralised online portals (e.g. ETax, TaxMe, FriTax), cantons now funnel you towards digital filing. The websites are integrated with the National ID system, enable safe uploading of any required document and are calculating taxes in real time.

The main advantages of Digitalisation:

* Faster filing: Online declaration allows people avoid queueing up during tax audits thereby getting the confirmation on taxes more quickly.

* Pre-filled documents: Employers are required to pass some details, especially via the Lohn-/Gehaltsausweis (payslip), directly to the taxpayers’ online dossiers.

* Errors are pointed out in advance: Validation rules ensure that there is no missing or erroneous entry which means that there is no need to re-do the declaration.

7. Opportunities for Tax Planning in 2026

Switzerland allows very substantial deductibility and allows extensive strategic planning of annual taxes.

Pension Contributions (Pillar 3a & Pillar 2)

Contributions to private pension schemes (Pillar 3a) offer immediate tax deductions from taxable income.

• Employed Individuals (with pension fund): Deduct up to the annual statutory maximum.
• Self-Employed Individuals (without pension fund): Deduct up to 20% of net earned income.

Additionally, voluntary buy-ins into an occupational pension fund (Pillar 2) provide significant tax relief while strengthening retirement security.

8. Wealth Management and Real Estate

Property Maintenance: Federal and cantonal deductions apply for home renovations and structural improvements with energy efficiency savings, as well as regular maintenance costs. Portfolio Management: If you entrust the management of your assets to a bank or financial institution, fees incurred for managing the securities will be tax-deductible. 8. What Expats Should Know Expats who relocate to Switzerland can enjoy a remarkably high quality of life, though it may come with tax regulations that are initially difficult for them to comprehend.

Tax advice by professionals specializing in expats can thus prove invaluable.

Swiss Tax Residency: Principle The criterion of tax residency is considered established when someone has no intention of permanently leaving Swiss territory, resides there for at least thirty consecutive days working, or spends ninety consecutive days as an economically active but employed resident. As a tax resident, an individual has unlimited tax liability in Switzerland for their global earnings and world-wide assets. Taxation At Source (Quellensteuer): Non-C permit foreign employees have most of their income and tax withheld by their employers directly from their monthly salaries. Any expatriate whose annual gross income is more than CHF120,000 (or if they possess significant foreign assets) must undergo a compulsory after-the-fact ordintary taxation assessment (Nachtragliche Ordentliche Veranlagung – NOV) of worldwide income and assets.

Cross-Border Assets and Double Taxation

Expatriates often retain assets in their home country, such as real estate, retirement accounts, or stock portfolios. Switzerland relies on double-taxation treaties (DTAs) to prevent the same income from being taxed twice. However, foreign real estate—while tax-exempt for income calculations in Switzerland—is still factored in to determine your global progressive tax rate (progression reservation).
