What is the definitive tax bill?
The definitive tax bill is based on your final income and asset situation and differs from provisional estimates.

What is the definitive tax bill?
The definitive tax bill is the final tax bill, based on the factors of the submitted tax return including any adjustments made by the tax authority. Unlike the provisional tax bill, the definitive bill is based not on an assumed estimate, but on the actual income and asset situation.
Usually, only a small amount needs to be paid with the definitive tax bill. The bulk of the tax liability is settled by the provisional tax bill, provided it has been paid. If extraordinarily high deductions were claimed in the tax return, a credit might even result in favor of the taxpayer.
When do I receive the definitive tax bill?
After the tax return has been submitted, it is assessed by the tax office and subsequently, the tax bill is sent out. The waiting times can vary greatly. If the tax return is extensive and is submitted between April and June, a longer waiting period can be expected compared to if the tax return is simple and submitted in November. The definitive tax bill must be paid within 30 days.
What is the purpose of the definitive assessment?
The definitive assessment provides an overview of the most important factors of the tax return and tax bill. Should there have been any corrections made by the tax office, these will be indicated under the rationale for deviation in the assessment. If one disagrees with the assessment, an appeal can be filed with the tax administration.
