The following cantonal specifics should be taken into account when filing your tax return in Basel-Landschaft:

• Full splitting in income tax: Married couples and families in Basel-Landschaft benefit from full splitting. The taxable income is halved for rate determination, which can significantly reduce the tax burden and provide targeted relief for families.
• Transparent valuation of securities: Listed securities are valued according to official price lists, while unlisted assets are assessed based on cantonal guidelines. This ensures a uniform and transparent calculation of wealth tax.
• Fair taxation of joint property: In the case of jointly owned real estate, income and expenses are divided according to ownership shares. This rule creates clarity — especially for cohabiting couples and other ownership communities.
• Annual tariff adjustment to counter inflation: Income tax rates in Basel-Landschaft are regularly adjusted to inflation to keep the tax burden stable and protect residents’ purchasing power.
• Municipal tax rate strongly impacts tax burden: Within Basel-Landschaft, municipal tax rates vary significantly. Those seeking to optimize their tax load should carefully consider their place of residence.
