Whether you’re a newcomer to Switzerland or a long-term expat, this guide will provide you with the knowledge and tools to navigate the Swiss tax landscape confidently.


Tax Filing Deadlines by Canton

Switzerland’s federal structure means that tax deadlines can vary significantly between cantons. Here’s a detailed overview of the regular and extended deadlines for each canton:


When is the Tax Filing Deadline in Zurich?

For residents of Zurich, the regular tax filing deadline is March 31st of each year. This means that for the 2024 tax year, your tax return should be submitted by March 31, 2025.

However, it’s important to note that:

  • Extensions are possible but must be requested before the deadline.
  • In Zurich City, extensions can be granted until September 30, 2025, and further extended to November 30, 2025, if requested after August 2025.

What are the consequences of not responding to a tax reminder in Zurich?

Here are the key consequences of not responding to a tax reminder in Zurich:

Initial reminder: If you miss the March 31st deadline to file your tax return in Zurich, you will first receive a reminder from the tax office. This initial reminder does not incur any fees in Zurich.
Discretionary assessment: If you fail to respond to the reminder and still do not file your tax return, the Zurich tax office will assess your income and tax liability at its own discretion. This often results in a higher tax bill than if you had filed yourself.
Fines: The Zurich tax office can impose fines for not submitting a tax return despite reminders. The fine amount is at the discretion of the tax office and can range from CHF 1,000 up to CHF 10,000 in serious cases.
Repeated non-filing: Repeatedly failing to file a tax return is considered a serious case and can result in higher fines. It may also be treated as potential tax evasion.
Interest on late payments: If fines are not paid within 30 days of receiving the notice, interest on arrears will be charged.
Limited appeal options: If you disagree with the discretionary assessment, you can file an objection within 30 days. However, you have to prove obvious errors and submit the missing tax return.
Risk of tax evasion charges: If the discretionary assessment is too low compared to your actual tax situation, you could face charges of tax evasion, resulting in back taxes and additional penalties.


To avoid these consequences, it’s crucial to either file your tax return on time, request an extension before the deadline if needed, or respond promptly to any reminders from the Zurich tax office.

Missing the tax filing deadline in Switzerland can have several consequences:

Reminders: You’ll receive a reminder from the tax office. In Zurich, these reminders are free, but other cantons charge fees (e.g., 35 CHF in Aargau, 60 CHF in Bern).
Discretionary Assessment: If you don’t respond to reminders, the tax office will estimate your taxable income and assets. This often results in a higher tax bill than if you had filed yourself.
Fines: You may be fined for violating procedural obligations.
Tax Evasion Charges: If the tax office’s estimate is too low, you could be charged with tax evasion, resulting in back taxes and additional fines.
Criminal Charges: In cases of tax fraud, you may face criminal charges. These include fines and potential imprisonment.
