Tax return deadlines in Aargau

The Aargau tax office sends out tax returns to individuals around mid-January each year, so they can be submitted on time. Deadlines for filing vary depending on the municipality. If you do not have time to collect your documents and file your return by the deadline, you can request an extension.

New resident in Aargau – where to submit your tax return?

If you have recently moved to the Canton of Aargau and are unsure where you are liable for taxes, the rule is simple: you are taxed in the canton where you were officially registered on December 31.
For example, if you moved from abroad or from the Canton of Bern to Aargau on July 31, you are still liable for the entire calendar year (January 1 to December 31) in Aargau and must file your tax return with the Aargau tax office.

Marriage – how does it affect your tax return?

The same December 31 rule applies. Your marital status on the last day of the year determines your filing status.
If you marry on July 31, you will be taxed as a married couple for the entire year. The tax office will issue one joint tax return, and the incomes and deductions of both spouses will be declared together.

Why are education costs not deductible, but continuing education costs are?

Education costs are incurred to open up a new source of income (e.g., university studies, school education, apprenticeships) and are considered personal living expenses. Therefore, they are not tax-deductible.

Continuing education costs, however, are incurred to maintain or improve an existing source of income (e.g., language courses, computer courses, professional certifications related to your current employment).

These costs are considered professional expenses and can be deducted from your taxable income with the appropriate documentation.
