Canton Glarus (GL) is a small alpine canton in eastern Switzerland. Like all Swiss cantons, it applies its own cantonal and communal income taxes in addition to the federal income tax. This page provides an overview of how income tax works in Glarus and serves as the entry point to more detailed sections on tax rates, deductions, filing requirements, special rules, examples and a simplified income tax calculator.

Position of Glarus in the Swiss Tax System

Swiss income taxation operates at three levels:

• Federal level – direct federal income tax, harmonised nationwide.
• Cantonal level – each canton, including Glarus, sets its own income tax law and tariffs.
• Communal level – communes apply tax multipliers on top of cantonal tax.

In practice, residents of Glarus pay:

• Federal income tax based on the federal tariff, and
• Cantonal and communal income tax calculated under Glarus’ tax law, including the applicable communal multiplier.
