Swiss Lump-Sum Taxation for Eligible Private Clients
Assess expenditure-based taxation eligibility, canton requirements and the comparison with ordinary Swiss taxation.
Overview
Expenditure-based taxation is available to qualifying foreign nationals who become Swiss tax resident for the first time or after at least ten years abroad and do not undertake gainful activity in Switzerland. Both spouses living together must meet the conditions. Managing a business or family office from Switzerland needs specific assessment; foreign clients or ownership alone do not establish eligibility.
How the Taxable Base Is Calculated
For tax year 2026, the federal minimum assessment base is CHF 435,000, not the tax payable. Worldwide living expenses and statutory housing-based minimums must also be considered. A separate control calculation can increase the tax due on specified Swiss income and treaty-relieved foreign income. Cantonal income and wealth-tax rules require a separate calculation.
Cantons
Zürich abolished cantonal expenditure-based taxation in 2010. Schaffhausen, Appenzell Ausserrhoden, Basel-Landschaft and Basel-Stadt also abolished it. For other cantons, obtain the current requirements from the relevant tax authority. A single national table of minimum payments cannot establish your eligibility or final liability.
Documents to prepare
Prepare passports and residence history for each family member, civil-status records, intended housing and insurance details, and evidence of income and assets. For business owners, include ownership charts, accounts and planned transactions. Share sensitive records only through the channel agreed for the engagement; the initial enquiry does not need a full financial dossier.
Before choosing a canton, assemble passports, residence history, a worldwide household budget, housing details, income sources and intended work activities. Coordinate a comparison with ordinary taxation and, where appropriate, a written ruling request through qualified tax specialists. Confirm its assumptions and reporting duties. Tax treatment and immigration permission are separate decisions; neither approval nor a fixed annual tax bill is guaranteed.
Process and deliverables
The initial assessment identifies your proposed residence basis, canton shortlist and unresolved specialist questions. The agreed engagement can then set out a document checklist, responsibilities and the sequence for tax, immigration, housing and banking. Legal opinions, tax filings and regulated financial services require the appropriate professionals and mandates. Confirm the scope and fees before work starts.
Timing and fees
Plan around document availability, specialist analysis, authority requests and family commitments. Approval dates cannot be guaranteed. Ask for a written scope separating coordination fees, specialist fees and official charges, with assumptions and exclusions. The first discussion should establish your target arrival date and the decisions that must precede it.
Questions to resolve
What residency permits are available in Switzerland?
B is a residence permit, L a short-stay permit, C a settlement permit and G a cross-border commuter permit. The appropriate category and its conditions depend on nationality, purpose of stay and the authority’s decision. For non-EU/EFTA nationals, the legal basis must be assessed individually. Employment, self-employment, retirement and exceptional admissions have different requirements. Wealth, a property purchase, company incorporation or a tax ruling does not by itself confer a residence permit. Cantonal and, where required, federal authorities decide; obtain an assessment before committing to a move.
