Nonresidents are subject to Schaffhausen wealth tax on assets that are economically connected to the canton. In practice, this limited tax liability mainly concerns real estate and business assets located in Schaffhausen, while foreign portfolios and movable property held abroad remain outside the Schaffhausen wealth-tax base.

This guide summarises the scope, valuation framework, and compliance requirements for the 2025 tax year for nonresident individuals with assets in the canton of Schaffhausen.

1. Scope of Limited Tax Liability

A nonresident becomes liable for Schaffhausen wealth tax if they hold any of the following:

• Residential or commercial real estate situated in the canton of Schaffhausen
• Land or agricultural property located within Schaffhausen
• Permanent establishments or fixed places of business (e.g., workshops, offices, hotels, restaurants, shops) in the canton
• Business assets allocated to a Schaffhausen branch, permanent establishment, or place of effective management

Assets outside Switzerland — such as foreign securities, overseas real estate, and non-Swiss bank accounts — are excluded from the Schaffhausen wealth-tax base, although they may still be relevant in the residence state for rate progression or reporting.

2. Valuation Basis

Schaffhausen applies cantonal valuation rules that are harmonised with federal law but implemented locally by the cantonal tax administration:

• Real estate: Cantonal tax value (Steuerwert), generally below open-market value
• Securities and bank assets: Year-end tax value using official federal tax value lists and FX rates
• Business assets: Book or fair value according to Swiss accounting standards, with Schaffhausen-specific adjustments where required
• Pension assets: Occupational and pillar 3a pension capital is typically exempt from wealth tax until payout

The Steuerwert for real estate reflects a fraction of market value determined by the Schaffhausen tax authority, based on location, use, and property type. For more technical detail on valuation in this canton, see Valuation Rules.

3. Debt Allocation

Debt allocation for nonresidents in Schaffhausen follows the Swiss principle of economic connection combined with proportional allocation:

• Mortgages secured on Schaffhausen property are deductible from the wealth-tax value of that property.
• Other debts are deductible only insofar as they can be economically tied to Swiss assets or allocated proportionally.
• If the taxpayer owns property in several Swiss cantons, total debt is allocated among cantons according to the relative taxable values of those assets.

Interest on debt is relevant for income tax and is apportioned across jurisdictions by reference to Swiss-sourced assets and income, including inter-cantonal allocation.

4. Allowances & Exemptions

Nonresident taxpayers in Schaffhausen generally do not benefit from the full range of personal allowances and social deductions granted to resident individuals. However, certain items are usually excluded from the wealth-tax base:

• Tax-exempt pension capital (2nd pillar and pillar 3a) until withdrawal
• Normal household goods and personal belongings
• Smaller technical exemptions required under harmonised cantonal law

For nonresidents, the effective Schaffhausen wealth tax burden is driven mainly by the property’s tax value, the cantonal and communal tax scales, and debt allocation.

5. Double Tax Treaties

Under Switzerland’s double tax treaties, taxation of immovable property is typically assigned to the state in which the property is located. As a result, Schaffhausen retains the right to tax real estate and related business premises situated in the canton, even when the owner is resident abroad.

Relief is usually provided in the country of residence through:

• Exemption with progression, or
• Foreign tax credit for Schaffhausen wealth tax against home-country wealth or property taxes.

It is important to check the specific treaty between Switzerland and your country of residence and to retain Schaffhausen tax assessments and receipts as proof of Swiss tax paid.

6. Swiss Tax Representative

Nonresidents will typically need to provide a Swiss correspondence address or appoint a tax representative when dealing with the Schaffhausen tax authorities.

• Swiss fiduciaries, tax advisors, or lawyers can act as authorised representatives.
• Official correspondence and assessments are issued in German.
• Using a representative helps manage deadlines, language issues, and any appeals or objections.

7. Filing & Compliance

Nonresident owners of property or business assets in Schaffhausen file a limited Swiss tax return covering Swiss-situs income and wealth. The wealth tax portion focuses on net taxable assets situated in Schaffhausen as at 31 December.

• Official confirmation of the property’s tax value (Steuerwert)
• Mortgage and loan confirmations as of year-end
• Rental income and expense statements for let property
• Business balance sheet and asset schedules where a Schaffhausen permanent establishment exists

Filing deadlines broadly align with those for resident taxpayers. Extensions are generally available upon request, often submitted via a Swiss representative.

8. Example — Nonresident Residential Property Owner

Profile: Resident of Germany, owns a residential property in the canton of Schaffhausen.

• Tax value (Steuerwert): CHF 800,000
• Mortgage balance: CHF 520,000
• Combined cantonal/municipal multiplier (illustrative): 1.50 (150 % of simple tax)

Step 1 — Net taxable wealth: CHF 800,000 − CHF 520,000 = CHF 280,000
Step 2 — Simple wealth tax (illustrative progressive rate): 3.0‰ of CHF 280,000 = CHF 840
Step 3 — Applying multipliers: CHF 840 × 1.50 = CHF 1,260
→ Indicative effective burden of about 0.45 % of net taxable wealth (illustrative only; actual rates depend on year and commune).

9. Ending Schaffhausen Tax Liability

Wealth tax liability in Schaffhausen normally ends when the property or business assets in the canton are sold, transferred, or otherwise disposed of. A final limited tax return must be filed and any remaining wealth tax and property gains taxes settled.

The Schaffhausen tax office should be notified promptly of the disposal to avoid continued assessments based on outdated ownership data.

10. Planning Insights for Nonresidents

• Obtain an estimate of the Schaffhausen tax value and local multipliers before acquiring property.
• Align mortgage structure and debt allocation with your broader cross-border wealth and estate planning.
• Review how Schaffhausen wealth tax interacts with home-country rules and relevant double tax treaties.
• Use a Swiss tax representative to manage filings, coordinate with your home-country advisor, and handle German-language correspondence.
