Nonresidents are subject to Basel-Landschaft 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 Basel-Landschaft, while foreign portfolios and movable property held abroad are not taxed in the canton.

This guide summarises scope, valuation, and compliance requirements for the 2025 tax year for nonresident individuals with assets in Basel-Landschaft.

1. Scope of Limited Tax Liability

A nonresident becomes liable for wealth tax in Basel-Landschaft if they hold any of the following:

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

Assets outside Switzerland — such as foreign securities, overseas real estate, and non-Swiss bank accounts — are excluded from the Basel-Landschaft wealth-tax base, but may be relevant in the country of residence for rate or reporting purposes.

2. Valuation Basis

Basel-Landschaft applies cantonal valuation rules that are harmonised with federal law but implemented through its own practice:

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

The Steuerwert for real estate in Basel-Landschaft normally reflects a fraction of market value, taking into account location, use, and property type. For further technical detail in this canton, see Valuation Rules.

3. Debt Allocation

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

• Mortgages secured on Basel-Landschaft property are deductible from the taxable wealth 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 split between jurisdictions based on Swiss-sourced assets and income, including allocation across cantons.

4. Allowances & Exemptions

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

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

For nonresidents, the effective burden is primarily driven by the Steuerwert, the progressive wealth tax scale, communal multipliers, and debt allocation.

5. Double Tax Treaties

Under Switzerland’s double tax treaties, taxation of immovable property is typically assigned to the state where the property is located. As a result, Basel-Landschaft retains the right to tax real estate and related business premises situated in the canton, irrespective of the owner’s residence.

Relief is usually provided in the country of residence through:

• Exemption with progression, or
• Foreign tax credit for Basel-Landschaft 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 Basel-Landschaft tax assessments and receipts as evidence of Swiss tax paid.

6. Swiss Tax Representative

Nonresidents normally need to provide a Swiss correspondence address or appoint a tax representative for dealings with the Basel-Landschaft 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, and any appeals or objections.

7. Filing & Compliance

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

• Official confirmation of the property’s Steuerwert
• Mortgage and loan confirmations as of year-end
• Rental income and expense statements for let property
• Business balance sheets and asset schedules where a Basel-Landschaft 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 Home Owner

Profile: Resident of Germany, owns a detached house in Basel-Landschaft.

• Steuerwert: CHF 1,000,000
• Mortgage balance: CHF 650,000
• Combined cantonal/municipal multiplier (illustrative): 1.50 (150 % of simple tax)

Step 1 — Net taxable wealth: CHF 1,000,000 − CHF 650,000 = CHF 350,000
Step 2 — Simple wealth tax (illustrative progressive rate): 3.0‰ of CHF 350,000 = CHF 1,050
Step 3 — Applying multipliers: CHF 1,050 × 1.50 = CHF 1,575
→ Indicative effective burden of about 0.45 % of net taxable wealth (illustrative only; actual rates depend on year and commune).

9. Ending Basel-Landschaft Tax Liability

Wealth tax liability in Basel-Landschaft 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 tax office should be notified promptly of the disposal to avoid continued assessments based on outdated ownership records.

10. Planning Insights for Nonresidents

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