German Tax Knowledge · § 8 AO
Tax Residence in Germany
Under § 8 AO, a person has a tax residence where they maintain a dwelling under circumstances indicating that they will retain and use it. The decisive factors are the actual facts and circumstances – not registration status, nationality or the center of vital interests.
§ 8 AO
Residence Is a Factual Connecting Factor Under German Tax Law
§ 8 AO defines residence independently for tax purposes. A natural person has a residence where they maintain a dwelling under circumstances indicating that they will retain and use it.
Tax residence is particularly important for determining personal tax liability. An individual with a residence or habitual abode in Germany is generally subject to unlimited German income tax liability under § 1(1) EStG.
The analysis is based on objectively recognizable facts. Registration or deregistration with the local authorities can be evidence, but it does not decide the tax question.
Statutory Elements
Three Elements Determine Residence Under § 8 AO
1. Dwelling
There must be fixed premises that are suitable for permanent living, even if only as modest accommodation. A fully equipped, self-contained apartment is not required.
2. Holding the Dwelling
The dwelling must actually be available to the individual. What matters is the practical ability to use it, not necessarily ownership or a lease in the individual’s own name.
3. Retaining and Using It
The overall circumstances must show that the dwelling is not used merely temporarily or by chance, but is retained as the individual’s own place to live.
Core Formula of § 8 AO
Dwelling + Control + Retaining and Using
The mere existence of a dwelling in Germany is not enough. Residence exists only if the premises are suitable for living, are actually available to the taxpayer and the objective circumstances indicate that they are retained and used as the person’s own home.
These three levels should be analyzed separately. In cases involving accommodation with relatives, standby apartments, second homes or homes retained after moving abroad, the decisive issue is often not whether there is a dwelling, but whether the person actually holds and uses it with residential character.
- dwelling: objectively suitable for permanent living
- holding: actual ability to use the premises
- retaining: not merely a temporary opportunity to stay
- using: use as the individual’s own home
- overall assessment of the actual facts
Meaning of a Dwelling
Even Modest Accommodation Can Qualify as a Dwelling
No Luxury or Full Equipment Required
According to the German tax administration, fixed premises that are suitable for permanent living can be sufficient. A separate kitchen or a bathroom integrated into the living area is not necessarily required.
A Mere Place to Sleep Is Not Always Enough
Living in premises goes beyond simply staying or sleeping there. Accommodation that is merely short-term, temporary or makeshift does not necessarily satisfy the dwelling requirement.
Administrative Guidance
The AEAO to § 8 Structures the Analysis for the German Tax Authorities
The Application Decree to the Fiscal Code (AEAO) breaks the residence analysis into several practical questions. The following points are particularly important:
Overall Assessment
Whether a dwelling is retained and used must be assessed based on the overall circumstances of the relevant tax period. Later developments may be considered only to the extent that they shed light on the facts that existed at that time.
Registration Is Only Evidence
The mere intention to establish or terminate residence, as well as registration or deregistration under local registration law, has no direct tax effect by itself.
Several Residences Are Possible
A person may maintain several dwellings and several tax residences at the same time. The German residence does not have to be the main residence or the center of vital interests.
No Minimum Number of Days
§ 8 AO does not prescribe a minimum number of days per year. Use at longer intervals can still be sufficient.
Use Must Have Residential Character
Mere visits, short holiday stays, purely administrative stays or exclusive use as an office or business premises are generally not sufficient.
Forward-Looking Time Element
The overall facts must indicate that residential use is likely to continue. The AEAO refers to the six-month period in § 9 AO only as an orientation for this time element. There is no six-month threshold for residence under § 8 AO.
Use
There Is No “183-Day Rule” for German Tax Residence
The 183-day threshold does not determine whether a person has a residence under § 8 AO. Residence can exist even with significantly fewer days in Germany if a dwelling remains actually available and is retained and used as the individual’s own home.
Conversely, a mere place to stay overnight or a short visit does not automatically establish residence. The residential character of the actual use remains decisive.
- no statutory minimum number of days
- no requirement for daily or monthly use
- use at longer intervals may be sufficient
- mere holiday or visiting stays are not enough
- § 8 AO and § 9 AO must be analyzed separately
Family Residence
Important Factual Presumptions Apply to Spouses and Families
The Family Remains in the Dwelling
For spouses or registered partners who are not permanently separated, the German tax administration generally assumes that residence exists where the family lives. This can apply even where the individual spends most of the time abroad.
Accommodation with Relatives
Regular stays with parents, other relatives or friends do not by themselves establish residence. The premises must actually be available as the individual’s own dwelling.
Minor Children
Minor children generally share the residence of their parents because membership in the parental household ordinarily provides a derived right to use the parents’ dwelling.
Each Person Is Analyzed Separately
Despite family-related presumptions, residence for tax purposes must ultimately be assessed separately for each individual based on their actual circumstances.
Living Abroad
A Residence Abroad Does Not Automatically Eliminate German Residence
The German Dwelling Remains Available
A person who establishes another residence abroad can still retain a German residence if the German dwelling remains actually available and continues to be kept as the person’s own home.
German Residence Despite Moving AbroadThe German Dwelling Is Actually Given Up
If the property is sold or rented out on a long-term basis so that the individual no longer has a personal right of use, this generally points toward termination of German residence.
Departure & Ending German ResidenceBFH Case Law
Leading Decisions on German Tax Residence
The case law of the German Federal Fiscal Court (BFH) focuses in particular on three questions: when a dwelling is actually available, when its use has residential character and how intensively it must be used. The decisions therefore translate directly into practical criteria.
No Minimum Number of Days
The BFH made clear that residence does not require the taxpayer to spend a specific minimum number of days or weeks per year in the dwelling.
Practical significance: A small number of days in Germany does not rule out residence. The decisive issue remains whether the dwelling is available as the individual’s own home and is actually used with residential character.
Official reference: BFHE 182, 296; BStBl II 1997, 447.
Actual Control and Regular Use
Residence requires that the taxpayer can actually use the dwelling and does so continuously or with a certain degree of regularity, even at longer intervals, as a place to live.
Practical significance: Ownership or a lease alone is not enough. Actual access and a genuine pattern of residential use are decisive.
Official reference: BFHE 193, 558; BStBl II 2001, 294.
No Center of Vital Interests Required
A German residence does not require the dwelling in Germany to be the center of the individual’s vital interests.
Practical significance: A complete center of life abroad does not automatically eliminate German residence. The domestic residence analysis under § 8 AO must be kept separate from any later treaty residence analysis.
Official reference: BFH/NV 2004, 917.
Standby Room: Availability for Residential Use
The requirement of holding a dwelling means that it must actually be available for residential use. In the case of a small standby apartment shared with others, that requirement may not be satisfied.
Practical significance: A theoretical possibility to stay overnight is not enough. Restrictions on use, co-users and the actual size or organization of the accommodation can prevent residence from arising.
BFH decisionObjective Availability and Residential Purpose
The dwelling must objectively be available as a place to live and must, based on the circumstances, be intended for a corresponding residential stay. This distinguishes residence from merely staying somewhere.
Practical significance: The analysis does not end with possession of a key or a formal right of use. The actual purpose of the premises as the individual’s own home must also be evident from the facts.
BFH decisionSeveral Years Abroad and a Room at the Parents’ Home
During a multi-year stay abroad, the mere existence of accommodation in the parents’ home is not necessarily sufficient. Actual use must go beyond visits, short holiday stays or purely administrative stays.
Practical significance: A permanently available room with parents or relatives is not automatically a German residence. The decisive issue is whether it is genuinely used as the individual’s own home.
BFH decisionMulti-Year Assignment Abroad: German Residence Can Continue
German residence can continue even during a multi-year assignment abroad. The BFH again confirmed that several residences are possible, no minimum period of presence is required and the German residence does not have to be the center of vital interests.
Practical significance: A long-term stay abroad does not by itself terminate § 8 AO residence. A German dwelling that remains available and is actually used can continue to trigger unlimited German tax liability.
BFH decisionPractical Analysis
Facts That Are Particularly Important in Practice
Access
Control over keys, personal rights of use, exclusion of third-party use and whether the dwelling can actually be occupied at any time.
Condition and Furnishings
Furniture, personal belongings and whether the premises can genuinely be used as a home without substantial preparation.
Pattern of Use
Duration, frequency and character of stays. Residential stays must be distinguished from visits or purely administrative stays.
Family
The family home, the presence of a spouse and children and the actual integration of the dwelling into family life.
Contracts
Leases, subletting, long-term rental to third parties and agreements that restrict the individual’s ability to use the dwelling.
Documentation
Travel records, calendars, handover records and other evidence can become decisive if the actual circumstances are disputed later.
