One. That is the number of corporate income tax systems a German company operates under at home. Fifty. That is the number of distinct corporate tax jurisdictions a German subsidiary may encounter in the US: one federal, 44 states with their own corporate income tax, four states with gross receipts taxes (Nevada, Ohio, Texas, and Washington) instead of income tax, and the District of Columbia.
The German tax system is one of the most predictable corporate environments in the developed world. Körperschaftsteuer at 15 percent, Solidaritätszuschlag at 5.5 percent of that, and Gewerbesteuer set by the municipality. Three components, one effective rate of roughly 30 percent, one filing schedule. The framework is stable enough that German CFOs build three-year forecasts to the nearest thousand euros.
The US runs on different logic. Federal corporate tax sits on top of state corporate tax. State corporate tax sits next to a separate sales tax system that operates in over 12,000 local taxing jurisdictions. None of this is administered by a single authority. None of it is unified across states. And since the Supreme Court’s 2018 decision in South Dakota v. Wayfair, even a company with no US physical presence can trigger sales tax collection obligations in dozens of states simultaneously.
For German owners and CFOs evaluating US expansion, the headline corporate tax rate is the smallest part of the story. The structural complexity is the cost. This guide sets out what changes, what to plan for, and where the budget and time both get consumed.
Why this matters before the first US invoice
The conversations Foothold America has with German CFOs at the planning stage almost always start with corporate tax rate comparisons. Germany at ~30 percent effective. US federal at 21 percent. The math looks favourable on the surface.
The math is also incomplete. Once a German subsidiary starts operating in the US, the tax exposure stops being a single rate and becomes a compliance footprint. Where the company has employees. Where it has inventory. Where it ships. Where it advertises. Where it earns revenue. Each of those creates a potential filing obligation in a state, sometimes a city, sometimes both.
The cost of running that compliance footprint, in software, accounting fees, and time, is the line item German finance teams routinely underestimate. Plan for it before the first US sale, not after.
For the wider commercial picture, our guide to expanding from Germany to the USA covers the full operational landscape. This blog focuses on the tax architecture.
The German tax system in 90 seconds
German owners know this. The contrast is the point, so here is how a US CFO would describe the German system to an American board.
Corporate Income Tax (Körperschaftsteuer) is levied at a flat 15 percent on taxable profits. The Solidaritätszuschlag adds 5.5 percent on top of the corporate tax amount, taking the federal effective rate to 15.825 percent.
On top of that sits Gewerbesteuer (trade tax), set by the municipality through a multiplier (Hebesatz) applied to a 3.5 percent base rate. The result for most large cities is a trade tax of 14 to 17 percent. Combined effective corporate tax sits at around 30 percent across Germany, with a range of roughly 23 to 33 percent depending on location.
VAT (Umsatzsteuer) is 19 percent standard, 7 percent reduced. One rate, one filing system, paid once. The framework is administered by one set of tax authorities, governed by uniform federal law, and predictable to the cent for budgeting purposes.
The US tax system in 90 seconds
The US has no single corporate tax framework. It has a federal layer, a state layer, and in many cases a local layer, all operating independently and all requiring separate filings.
At the federal level, the corporate income tax rate is a flat 21 percent under the Tax Cuts and Jobs Act of 2017. That part is simple. From there it gets layered.
Forty-four states levy their own corporate income tax, with top rates ranging from 2.25 percent in North Carolina to 11.5 percent in New Jersey, per the Tax Foundation’s 2025 data. The median is 6.5 percent. Six states use a different structure: Nevada, Ohio, Texas, and Washington apply gross receipts taxes on revenue rather than profit. South Dakota and Wyoming impose no corporate income or gross receipts tax at all. Delaware applies an annual franchise tax on top of any income tax obligation.
Then there is sales tax. Forty-five states plus the District of Columbia operate a state sales tax system. Local jurisdictions layer their own rates on top. Combined state and local sales tax rates exceed 10 percent in Chicago, Birmingham, and parts of Los Angeles County. The five states with no statewide sales tax are New Hampshire, Oregon, Montana, Alaska, and Delaware (the NOMAD states), although Alaska permits local sales taxes.
And then there is payroll tax. Federal FICA (Social Security and Medicare) plus FUTA (federal unemployment). Each state runs its own unemployment insurance system with its own rates. Some states and cities also levy local income tax withheld from employee wages. New York City, San Francisco, Philadelphia, and Portland are obvious examples.
None of this is unified. None of it is filed through one return. And each layer carries its own audit risk.
The two systems side by side
Element | Germany | United States |
Corporate income tax jurisdictions | 1 federal system | 1 federal + 44 state systems + 4 gross receipts states |
Headline corporate income tax | 15% Körperschaftsteuer | 21% federal flat rate |
Surcharges and add-ons | 5.5% Solidaritätszuschlag on corporate tax | State corporate tax ranging 2.25% to 11.5% (top rate, NJ) |
Local business tax | Gewerbesteuer 14-17% effective by municipality | Some cities and counties levy additional business or gross receipts taxes |
Combined effective corporate rate | ~30% (range 23-33%) | ~21% federal alone; state stack typically pushes total to 25-30% |
VAT / sales tax | Umsatzsteuer 19% standard, 7% reduced, uniform nationally | Sales tax in 45 states + DC; over 12,000 local jurisdictions |
Sales tax obligation trigger | Standard VAT registration once trading | Physical or economic nexus per state, post-Wayfair (2018) |
Filing burden | One corporate tax return, monthly/quarterly VAT | Federal return + state returns + sales tax returns + payroll filings per state |
Tax administration | One Finanzamt per region under federal framework | IRS + state revenue departments + local agencies, none unified |
The headline difference is structural. Germany taxes through a single coordinated framework with three components. The US taxes through a federation of overlapping frameworks that share no common administrator.
A view from the conversations Jack is having in Germany
“German CFOs I meet are some of the best-prepared finance leaders I work with anywhere in Europe,” says Jack Pieters, Senior US Expansion Advisor at Foothold America, based in Germany. “They build precise models. They know their Hebesatz to the percentage point. The shock is not that US tax is higher, because in many cases it is not. The shock is that there is no single number. The compliance footprint scales with where the business operates, not with how much it earns. That is the part German finance teams need to model before they sign off on a US expansion budget.”
The five US tax surprises German CFOs need to plan for
1. Federal tax is the easy part. State tax is where complexity lives.
Federal corporate income tax in the US is 21 percent flat. There is no surcharge, no local multiplier, no Gewerbesteuer-style variation. For a German CFO, this looks beautifully clean.
State corporate tax is where the layering begins. A subsidiary headquartered in California (8.84 percent) and selling into New Jersey (11.5 percent top rate) and Pennsylvania (7.49 percent in 2026) may owe corporate income tax to all three. The rules for apportioning income across states (single sales factor, three-factor formula, market-based sourcing) vary by state and matter as much as the headline rate.
What to do instead. Model effective tax based on your actual sales footprint, not the rate of the state of incorporation. The state of incorporation choice (Delaware is the typical answer for international parents) does not exempt you from owing tax where you actually do business.
2. Sales tax is not VAT. It is 12,000 jurisdictions and growing.
In Germany, VAT is a value-added tax: charged at each step, claimed back by registered businesses, ultimately paid by the end consumer. One system, one rate structure.
In the US, sales tax is a transactional tax charged only on the final sale to the end user. Rates vary by state, county, and city. Combined rates exceed 10 percent in some jurisdictions. Most US sales tax is not recoverable by business buyers in the way VAT is in the EU, which creates a real cash flow drag on B2B transactions where exemption certificates are not in place.
What to do instead. Build a sales tax software stack from day one (Avalara, TaxJar, Anrok, or similar). Manual sales tax compliance across multiple states is not a viable long-term option. Our team helps German clients select and configure the right one.
3. Wayfair changed the rules for international sellers.
In June 2018, the US Supreme Court ruling in South Dakota v. Wayfair, Inc. abolished the physical presence requirement for sales tax. After Wayfair, all 45 sales tax states have enacted economic nexus rules. The most common threshold is $100,000 in annual sales into a state, with some states using 200 transactions as a secondary trigger (though many states have since dropped the transaction threshold).
For a German company selling SaaS or e-commerce into the US, this means sales tax obligations can arise in 30+ states from remote sales alone. Each state requires registration, periodic filing, and the right rate applied to each transaction by destination.
What to do instead. Run a nexus study before your first significant sales month, not after. We build this into the US entity setup process for clients projected to cross thresholds quickly.
4. Payroll tax is fragmented by state and sometimes by city.
In Germany, payroll taxation is uniform under federal law. In the US, federal FICA and FUTA are federal, but every state runs its own unemployment insurance (SUI) system with its own rates and wage bases. Some states have state disability insurance, paid family leave levies, or workers’ compensation rate structures that vary by industry classification.
Then there are local income taxes. New York City, Philadelphia, San Francisco, and Portland are well-known examples, but cities in Ohio, Pennsylvania, and Kentucky have local wage taxes that surprise German payroll teams unfamiliar with sub-state taxation.
What to do instead. Run US payroll through a provider that handles multi-state and local registrations natively. Our Employer of Record (EOR) service and PEO+ Cross-Border Support take this off the German finance team entirely, which is where most clients want it.
5. State income tax shapes employee compensation conversations.
This one catches German CFOs late. An employee earning $120,000 in Texas, Florida, or Tennessee takes home meaningfully more than an employee on the same salary in California, New York, or New Jersey. The difference is state personal income tax, which can reach 13.3 percent at the top in California.
For German companies hiring across multiple US states, this means equivalent take-home pay can require different gross salaries by location. Compensation benchmarking that ignores state tax produces uncompetitive offers in high-tax states and overpaid hires in no-tax states.
What to do instead. Build state tax into compensation benchmarking from the start. Our Exclusive Talent Acquisition team builds this into every hiring brief for German clients.
Where to incorporate: the Delaware question
Almost every conversation we have with German clients on entity setup touches the same question: should we incorporate in Delaware? The answer is usually yes, with caveats.
Delaware’s appeal is its corporate law framework, the Court of Chancery (a specialised business court with deep precedent), and the predictability that US investors and lenders expect. Approximately 66 percent of Fortune 500 companies are incorporated in Delaware, and the state added nearly 290,000 new business entities in 2024.
Incorporating in Delaware does not exempt the company from owing tax in the states where it actually operates. A Delaware C-Corporation that hires employees in California and sells into Texas pays California state tax on California-apportioned income and registers for Texas franchise tax. The Delaware structure controls corporate law and governance, not where tax is owed.
Our GmbH vs C-Corporation vs LLC guide covers the entity decision in detail.
What this means for German finance teams
German CFOs preparing a US expansion budget should build the tax architecture into three categories.
One. Direct tax exposure. Federal 21 percent plus weighted state corporate tax based on actual operating footprint. For most US operations, the all-in effective rate sits between 25 and 30 percent, which is similar to or slightly below Germany.
Two. Indirect tax compliance. Sales tax registration, software, and ongoing filings across the states where economic or physical nexus exists. Budget for software, monthly filings, and dedicated accounting time.
Three. Payroll tax administration. Multi-state payroll, unemployment insurance, workers’ compensation, and local wage taxes where applicable. This is the operational cost that scales with headcount, not revenue.
The first category is what most German finance teams plan for. The second and third are where the time and money quietly accumulate, and where outside support pays back fastest.
“German finance teams are usually the easiest to work with on tax setup,” says Laurie Spicer, Director of US Expansion at Foothold America. “They understand precision. The work is mapping their precision onto a system that does not have a single source of truth. Once they see where the layers sit, which ones they own, and which ones we handle for them, the budget conversation becomes a planning conversation. The companies that get this right at the entity setup stage avoid the rework that catches the others six months in.”

Frequently Asked Questions: US vs German Tax
Get answers to all your questions and take the first step towards a US business expansion.
For most US operations, the combined federal (21 percent) and state corporate tax produces an effective rate between 25 and 30 percent. The exact rate depends on which states the subsidiary operates in and how income is apportioned between them.
No. Delaware incorporation controls corporate law and governance. The company still owes state tax in any state where it has employees, property, or sales nexus. Delaware is chosen for its legal framework, not as a tax shelter.
US sales tax is charged only on the final sale to end users and is generally not recoverable by business buyers, except where exemption certificates apply. German VAT is charged at each step and is fully recoverable by registered businesses, making it cash flow neutral for B2B.
After the Wayfair ruling, registration is triggered by economic nexus, typically $100,000 in annual sales into a state or 200 transactions where that secondary threshold still applies. Each of the 45 sales tax states has its own thresholds and rules.
Federal FICA (Social Security and Medicare, 7.65 percent each side) and FUTA (federal unemployment) apply nationally. Every state operates its own unemployment insurance system, and some states and cities levy additional local income tax withheld at payroll.
