Why is the tax report so important?

The tax report is not only a legal obligation, but also an opportunity to properly calculate and optimize one's tax load.

Avoiding mistakes and fines

False or incomplete details can lead to supplementary claims, default interest, or even fines.

Optimizing one's tax load

Legal deductions can help reduce the tax burden.

Legal certainty

Individuals who file their tax report correctly have nothing to fear in case of tax reviews or later adjustments of their tax bill.

Annual obligation

The tax report is not a one-off event, but needs to be filed on time every year.

Duties of persons subject to tax

As a person who is subject to tax, you are responsible for filing your tax report correctly, in full, and on time. This includes the following duties:

1

Truthful and complete information

  • All income (e.g., salary, net income, rental income) must be declared.

  • Assets (e.g., bank accounts, securities, real estate) must be listed in full.

  • Debt and mortgages must also be listed correctly.

2

Compliance with notice periods

  • Most cantons require tax reports to be filed by March 31.

  • Should more time be needed, a deadline extension can be requested.

  • In case of a missed deadline, reminder fees may be charged or, in the worst case, authorities may decide to estimate the amount of tax, which tends to lead to a higher tax burden.

3

Diligence and precision

  • All statements (e.g., salary statements, bank account statements, proof of deductions) should be kept and listed correctly.

  • Incorrect or incomplete information can lead to supplementary claims or tax audits.

  • The tax report should not be filled out in a hurry, but conscientiously.

4

Tax honestly – Trust and responsibility

  • The Swiss tax system is based on self-declaration and trust.

  • Deliberately making false statements or concealing income amounts to tax evasion, which can result in supplementary claims and fines.

  • Intentionally evading taxes may result in criminal proceedings (depending on the severity of the case).

5

Annual recurrence & adjustments

  • One's personal financial situation changes repeatedly (e.g., new job, marriage, home purchase). Such changes must be properly reflected in the tax report.

  • New deductions or a change in tax legislation can have an impact on one's tax declaration.

To conclude

The tax declaration is a recurring duty that must be handled with the necessary care and honesty. Those who start collecting all relevant documents early and stick to the deadlines can avoid a great deal of trouble and even save taxes.
