Taxation Procedure

1. Introduction

German tax law is known to be complex and interwoven with many legal intricacies. For this reason, it is important to pay attention to the specifics in order to better navigate the jungle of tax law. In this article, we aim to provide you with a small guide to explain the fundamentals of the taxation procedure. Additionally, we want to clarify the working methods of the tax administration and demonstrate why it is important to be familiar with the tax regulations.

2. Important Terms

In connection with tax regulations, certain terms are of central importance. These terms, such as residence, unlimited tax liability, and relatives, play a significant role in determining tax obligations.

Residence/Usual Place of Abode

Residence and usual place of abode are crucial for determining whether a person is subject to unlimited tax liability. Residence is defined as the place where a person has a dwelling and intends to maintain and use it. The usual place of abode, on the other hand, is where a person stays under circumstances that suggest they are not just temporarily present. These terms are essential for the question of whether someone is subject to unlimited tax liability in Germany.

(Un-)limited Tax Liability

Unlimited tax liability exists when someone has their residence or usual place of abode domestically. In this case, all income must be taxed domestically. Limited tax liability, on the other hand, occurs when someone is subject to limited tax liability with their domestic income, for example, employees who live abroad and work in Germany.

Relatives

In tax law, relatives are defined as fiancés, spouses, direct line relatives, siblings, and their spouses. The concept of relatives plays a role when tax-relevant contracts are to be concluded within this group of persons.

3. Course of the Taxation Procedure

In many cases, the term "taxpayer" is significant. This refers to persons who owe a tax or are liable for a tax, must file a tax return, or fulfill other tax obligations.

Identification Numbers

In the income tax return, an identification number is regularly requested. This serves for unique identification in the taxation procedure and must be communicated to the tax office.

Economic Identification Number

Since November 2024, natural and legal persons will be assigned an economic identification number. This is intended to simplify communication with authorities and automate tax processes.

4. Tax Assessment

The tax assessment marks the beginning of the tax administrative procedure. Here, the taxes that must be paid are determined, and with the collection of the tax, a second step is initiated.
