Last call: tax return deadline for companies in Zug and Zurich - 30th September approaching

Sep 22

Running a business in Switzerland comes with many advantages, from political stability to a competitive tax environment. However, every company must also stay compliant with Swiss tax regulations. One of the most important compliance tasks is the submission of the annual tax return.

For companies registered in Zug and Zurich, the official deadline to file corporate tax returns is 30th September of the following year. Missing this deadline can lead to penalties, interest charges, and complications with cantonal tax authorities.

With only a few days left, businesses must act quickly to stay compliant.

What you need to do before 30th September

To file your company’s tax return, we will need the following:

Annual financial statements (balance sheet, profit and loss, notes). If these haven’t been prepared yet, we can assist
Relevant supporting documents (invoices, contracts, bank statements)
Tax return form

If your accounts are not yet finalized or your documentation is incomplete, don’t worry, we can request an extension from the tax authorities.
