TL;DR:
US businesses face a dual tax system. Federal taxes, managed by the IRS, include income tax and payroll taxes. State taxes, which vary widely, can include corporate income tax, franchise tax for the right to exist in that state (like Delaware's), and sales tax based on where customers are located. Compliance requires managing both layers.
Direct Question Answer
What is this about? An explanation of the two-tier tax system in the US, detailing the differences between federal obligations (IRS) and state-level obligations (e.g., Delaware Division of Revenue). Who is it for? Founders of US companies, especially non-residents, who need to understand their full tax burden. When is it relevant? Annually, when preparing for tax season and planning for compliance costs.
Decision Summary
Who should act? Every US company must understand and plan for both federal and state tax filings and payments. Who can ignore? No one. Ignoring either layer of tax obligation will lead to penalties, loss of good standing, and potential business dissolution.
Unlike many countries with a single national tax authority, the United States operates on a system of federalism. This means your business is subject to laws and taxes at both the national (federal) level and the individual state level. For founders, especially those from outside the US, this dual system is often a source of major confusion and compliance risk.
It’s not enough to just file with the IRS; you must also satisfy the unique requirements of your state of incorporation and any other state where you have "nexus." This guide clarifies the distinct roles and obligations of federal vs. state tax compliance.
Federal Tax Obligations: The IRS
Federal taxes are administered by the Internal Revenue Service (IRS) and apply uniformly to all businesses across the country, regardless of where they are incorporated or located.
Key Federal Taxes for Businesses:
- Corporate Income Tax: A tax on the net profits of your company. This is filed annually via forms like the Form 1120 for C-Corps or Form 1065 for partnerships/multi-member LLCs.
- Payroll Taxes (FICA & FUTA): If you have W-2 employees, you must withhold and remit Social Security, Medicare (FICA), and federal unemployment (FUTA) taxes.
- Informational Returns: For foreign-owned companies, this includes the critical Form 5472, which reports transactions with foreign owners.
Think of federal taxes as the universal cost of doing business in the United States.
State-Level Obligations: A Complex Patchwork
State-level obligations are where things get complicated, as every state has its own set of rules. Your obligations depend on your **state of incorporation** and any states where you have **nexus**.
1. Taxes in Your State of Incorporation:
This is the state where you registered your LLC or C-Corp (e.g., Delaware, Wyoming). You owe this state compliance duties simply for existing there.
- Franchise Tax: This is NOT a tax on profit. It's a fee for the "privilege" of having a company in that state. Delaware's franchise tax is a well-known example. It's due every year, even with zero revenue.
- Annual Report: A filing to keep your company's information (like its address and directors) up to date. This often has a fee associated with it. Wyoming's Annual Report is a key example.
Our Annual Compliance service is designed to handle these specific state of incorporation filings.
2. Taxes in States Where You Have "Nexus":
"Nexus" is a connection between your business and a state that obligates you to follow that state's tax laws. It can be created by:
- Physical Nexus: Having an office, employee, or inventory in that state.
- Economic Nexus: Exceeding a certain threshold of sales into that state (e.g., $100,000 in sales).
If you have nexus in a state, you may be required to file:
- State Corporate Income Tax: A tax on the portion of your company's profit that is attributable to that state.
- Sales Tax: You must register to collect and remit sales tax from customers in that state.
| Tax Type | Federal Level (IRS) | State Level |
|---|---|---|
| Income Tax | Applies to net profit (income minus expenses). Universal across the US. | Varies. Some states have it, others (like Wyoming, Texas) do not. |
| Franchise Tax | Does not exist at the federal level. | A fee for the 'privilege' of existing in a state. Delaware and California are notable examples. |
| Sales Tax | Does not exist at the federal level. | Levied by 45 states. Based on the customer's location, not the seller's. |
| Governing Body | Internal Revenue Service (IRS) | Each state's Department of Revenue. |
The Bottom Line: Manage Both Layers
Successful US tax compliance means managing two distinct but interconnected systems. You must satisfy the IRS at the federal level while also tracking and fulfilling your obligations to each individual state where you are registered or have nexus.
