Employees in the U.S. · German Employer
German employer with employees in the United States
When a German company employs staff in the United States, U.S. payroll, federal and state registration, social security and tax issues can arise. At the same time, the employee's activities may create a U.S. permanent establishment or other taxable presence for the German company. Payroll, corporate taxation and German employer obligations should therefore be coordinated.
Starting point
One employee in the U.S. can trigger several obligations at the same time
A German business may send an existing employee to the United States, hire an employee directly in the U.S. or employ staff through a U.S. subsidiary. These models can produce very different tax, payroll and social-security consequences.
Relevant factors include the employee's work location, duration of stay, legal and economic employer, cost allocation, supervision, job functions and the particular U.S. state.
The analysis should therefore not be limited to the employee's individual income tax. Employer registrations, payroll, social security, permanent-establishment risk, state nexus and transfer pricing may all be relevant.
Employment models
Three typical arrangements
Assignment from Germany
The German employment agreement remains in place while the employee works temporarily in the United States. Tax, payroll and social security must be coordinated for the assignment period.
Direct U.S. employment by the German company
The German company employs a worker directly in the United States and can thereby create U.S. employer, payroll and state-registration obligations.
Employment through a U.S. subsidiary
A U.S. corporation or other local entity is the employer. Intercompany costs, transfer pricing and the actual economic allocation of the employee's activities must then be reviewed.
U.S. payroll
A German employer may be required to operate U.S. payroll withholding
If an employee physically works in the United States, the German employer may have to register for U.S. payroll purposes and withhold and remit employment taxes.
In addition to federal payroll taxes, state and sometimes local payroll obligations can arise. The required registrations depend on where the employee works and whether the employer becomes subject to local tax or employment-law requirements.
Federal withholding
U.S. federal income-tax withholding and the relevant employer filings must be reviewed based on the employment relationship and the employee's U.S. tax status.
FICA
Social Security and Medicare may generally apply to U.S. employment unless the Germany–U.S. social security agreement assigns coverage to the German system.
State payroll
Individual states may impose income-tax withholding, unemployment-insurance and employer-registration obligations.
Employee income tax
Employment income may need to be reported in both the U.S. and Germany
If a German-resident employee works in the United States, the portion of compensation attributable to U.S. workdays may become taxable in the U.S. The extent of U.S. taxation depends on U.S. domestic law and the Germany–U.S. tax treaty.
If German tax residence continues, the employment income must also be reflected in the German income-tax return, with double taxation addressed under the applicable treaty rules.
For longer assignments, the employee's tax residence itself may change. Employer payroll and the employee's individual tax filings should therefore use the same residency and workday records.
Permanent establishment
An employee can create a U.S. permanent establishment of the German company
Employing a person in the United States does not automatically create a permanent establishment. It can, however, become relevant if the German company has a fixed place of business available to it or if the employee performs functions that create taxable presence under the treaty.
Permanent offices, employer-used home offices, sales and management functions and employees with a substantial role in concluding contracts require particular attention.
Fixed place of business
An office, workstation or other premises can be relevant where they are available to the German company on a sufficiently permanent basis.
Home office
A U.S. home office is not automatically a PE. Duration, business necessity and the company's ability to use or control the premises are important factors.
Contract functions
Sales staff and other employees with a significant role in contract conclusion can create additional permanent-establishment issues.
State tax & nexus
An employee may create state obligations even without a federal PE
The Germany–U.S. tax treaty generally limits federal income taxation but does not resolve all tax obligations at state level.
An employee can therefore create payroll, income-tax or franchise-tax nexus, as well as registration and filing obligations for the German business in a state even where no taxable permanent establishment exists for federal income-tax purposes.
The state analysis should therefore be performed separately for the employee's actual work state.
U.S. subsidiary
Employment through a U.S. subsidiary requires correct economic allocation
If a U.S. subsidiary exists, it can employ the individual locally. This does not end the cross-border analysis. It must still be determined which company actually benefits from the employee's work and which entity should economically bear the employment costs.
If the employee primarily performs functions for the German parent, intercompany cost allocations or service charges may be required. Those charges must satisfy the arm's length principle.
Employer function
Employment agreement, supervision, personnel decisions and economic integration should be consistent.
Cost allocation
Salary, bonus, benefits and other personnel costs should be allocated to the entity that economically benefits from the employee's functions.
Transfer pricing
Cost recharges and intercompany services should be supportable and structured on an arm's length basis.
Benefits & compensation
German compensation components may be treated differently in the U.S.
International compensation often includes more than base salary. Bonuses, company cars, equity compensation, German occupational pension benefits, travel expenses and other benefits can be taxed differently in Germany and the United States.
For long-term incentives, the portion economically attributable to German and U.S. workdays may need to be determined. Payroll data should be able to support that allocation.
Employment law & other registrations
Payroll is not the only local employer obligation
Depending on the state, employment-law registrations, workers' compensation, unemployment insurance and other local employer requirements may apply in addition to tax and social security.
These obligations are separate from tax law but should be organized together with payroll and the chosen U.S. employment structure from the beginning.
Practical approach
The employment model should be determined before U.S. work begins
Analyze the employment
Identify the work state, duration, duties, contracting authority, employer and economic cost bearer.
Determine tax & social security
Review U.S. tax status, treaty rules, Social Security and any Certificate of Coverage requirements.
Set up payroll & registrations
Organize federal and state payroll and necessary employer registrations before the first U.S. payroll period.
Review company-level consequences
Coordinate permanent-establishment risk, state nexus, intercompany costs and transfer pricing with the employee's individual taxation.
Common mistakes
U.S. employment is often treated too narrowly as a payroll issue
Reviewing payroll only after work begins
The employee starts working in the U.S. before federal and state employer registrations have been established.
Failing to coordinate social security
German and U.S. Social Security are handled separately even though the bilateral agreement may assign coverage to one system.
Missing permanent-establishment risk
The employee's individual tax is reviewed, but not whether the employee's activities create U.S. tax exposure for the German employer.
Underestimating state tax
The treaty analysis focuses on federal tax even though the work state may have separate nexus and filing rules.
Incorrect cost allocation
A U.S. subsidiary bears the employee's costs even though the employee primarily performs functions for the German parent.
No workday documentation
Without reliable travel and workday records, payroll, treaty allocation and individual tax returns become difficult to reconcile.
FAQ
Frequently asked questions about employees of German companies in the U.S.
Can a German GmbH directly employ a person in the United States?
In principle, yes. This can, however, create U.S. federal and state employer registrations, payroll, employment-law requirements and potentially U.S. tax obligations for the German GmbH.
Does a German employer have to run U.S. payroll?
It may be required where the employee earns compensation subject to U.S. employment and payroll taxation. The exact obligations depend on the employment model, work state and applicable social-security coverage.
Can German social security continue during a U.S. assignment?
Under the Germany–U.S. social security agreement, German social-security coverage may continue for a qualifying temporary assignment. This should be documented through the appropriate Certificate of Coverage.
Can a single employee create a U.S. permanent establishment?
Yes, depending on the facts, but not automatically. Relevant factors include the employee's functions, fixed workplace, duration of the activity and role in concluding contracts.
Does the Germany–U.S. tax treaty protect against state tax?
The treaty generally applies to federal taxation. U.S. states are not necessarily bound by all treaty provisions, so state tax and nexus must be reviewed separately.
Is a U.S. subsidiary always better than direct employment?
No. A local company can simplify local employment and payroll but creates its own formation, accounting, tax and compliance obligations. The appropriate structure depends on the scale and expected duration of the U.S. activity.

Germany–U.S. Social Security
The social security agreement can prevent double contributions
Germany and the United States have a social security agreement that determines which country's social-security system applies to cross-border employment.
For a qualifying temporary assignment, German social-security coverage may continue. A Certificate of Coverage can then document that parallel U.S. Social Security contributions do not apply.
