Staying compliant with U.S. regulations is mandatory for foreign-owned companies operating in the U.S. Compliance involves meeting federal and state requirements, filing taxes, maintaining proper records, and adhering to deadlines. Missing key filings like IRS Form 5472 or state franchise taxes can result in penalties starting at $25,000, legal barriers, or even company dissolution.
Key Points:
- Federal Compliance: Requires filing IRS Form 5472 and pro forma Form 1120, even if no income is earned. Missing deadlines leads to steep penalties.
- State Compliance: Includes annual reports, franchise taxes, and maintaining a registered agent. Rules and costs vary by state.
- Sales Tax Nexus: Economic nexus laws mean businesses exceeding $100,000 in sales or 200 transactions in a state must register, collect, and remit sales tax.
- Recordkeeping: Keep financial and transactional records for at least 5–7 years to support audits and accurate filings.
Tip: Use compliance tools or professional services to manage complex multi-state operations and avoid costly mistakes.
Federal Tax Filing Requirements
Foreign-owned U.S. companies face additional federal tax responsibilities, with one of the most critical being the filing of IRS Form 5472. This form ensures transparency by reporting financial transactions between foreign shareholders and U.S. corporations.
IRS Form 5472 and Pro-Forma Form 1120
If a U.S. corporation has at least one direct or indirect foreign shareholder owning 25% or more of the company, or if a foreign corporation is conducting business in the U.S., it qualifies as a "reporting corporation" and must file Form 5472. The form is required whenever there are reportable transactions with related parties, such as sales, rents, or other exchanges involving monetary consideration.
Form 5472 must be filed along with the company's income tax return by the deadline, including any extensions. For foreign-owned U.S. disregarded entities, a pro forma Form 1120 - which only requires basic identifying information - must accompany Form 5472. It’s important to note that these entities must use a specific mailing address since electronic filing is not an option. If more time is needed, an extension can be requested using Form 7004.
Failing to comply comes with hefty penalties. Missing the filing deadline or submitting incomplete information results in a base penalty of $25,000. If the issue isn’t resolved within 90 days after receiving notification from the IRS, an additional $25,000 penalty is charged for every 30-day delay. For false or fraudulent filings, criminal charges may also apply.
In addition to filing compliance, obtaining a valid Employer Identification Number (EIN) is a mandatory step for all federal tax-related communications.
Employer Identification Number (EIN)
An Employer Identification Number (EIN) is a critical component of federal tax compliance. Acting as your company’s federal tax ID, it’s required for all IRS filings and communications. Every U.S. company, including foreign-owned entities, must secure an EIN before starting operations or opening bank accounts.
Foreign-owned companies can obtain an EIN by submitting Form SS-4 to the IRS. Applications can be made online, by mail, or by fax, though processing times will vary depending on the method used. Once issued, the EIN is permanent and remains tied to the company throughout its lifetime, even if ownership changes. However, significant structural changes, such as converting an LLC into a corporation, may necessitate applying for a new EIN.
It’s equally important to keep the IRS informed of any major changes, such as adjustments to ownership percentages or business structure. Keeping your EIN up to date ensures smooth processing of tax filings and helps maintain compliance year after year.
State Annual Reports and Franchise Taxes
Federal filings ensure your tax compliance, but state requirements are what keep your business legally active in each jurisdiction. Every state where your foreign-owned company operates or is incorporated has its own rules for annual reports, franchise taxes, and registered agent obligations. Staying on top of these is essential to maintain good standing.
Annual Report Filings by State
Most states require businesses to file annual reports, which update key details like addresses, officer information, and business activities. These filings help states monitor active businesses and ensure compliance with local laws.
For example, Delaware has specific requirements depending on your business structure. Delaware LLCs pay a flat franchise tax of $300 due on June 1, with no separate annual report required.
Wyoming is known for its low-cost compliance, requiring annual reports for both LLCs and corporations. The process is straightforward, with minimal fees.
Missing deadlines for these filings can have serious consequences. In Delaware, failing to pay the franchise tax could result in the dissolution of your company. Since each state has different deadlines, keeping track of due dates is critical. Some states offer online filing with instant confirmation, while others rely on paper submissions that take longer to process.
Franchise Taxes and Registered Agent Requirements
In addition to annual reports, states impose franchise taxes and require registered agents to handle legal and official communications. Franchise taxes are essentially fees for the privilege of operating in a state. Unlike income taxes, these must be paid even if your company incurs a loss, making them a fixed expense.
The way franchise taxes are calculated varies widely. For instance:
- California: Corporations face an $800 minimum franchise tax, though newly incorporated companies get a first-year waiver.
- Mississippi: The tax is $2.50 per $1,000 of capital value used in the state.
- Delaware: Franchise tax rates range from $175 to as much as $250,000 annually, depending on the corporation's size and filing method.
| State | Business Type | Annual Tax | Due Date | Notes |
|---|---|---|---|---|
| Delaware | C-Corporation | $225-$250,000+ | March 1 | Includes annual report |
| Delaware | LLC | $300 | June 1 | Flat tax, no report required |
| California | Corporation | $800 minimum | Varies | First-year waiver available |
| Mississippi | Corporation | $2.50 per $1,000 | Varies | Based on capital value |
Every state also requires a registered agent - a designated person or service with a physical address in the state - to receive legal documents and official notices during business hours. This is mandatory in every state where your company operates.
Failing to maintain an active registered agent can lead to administrative dissolution. Professional registered agent services, which often include electronic document delivery, typically cost between $100 and $300 annually. These agents act as your business's official point of contact for state authorities, ensuring you don’t miss critical communications like legal summons or annual report reminders. Overlooking this responsibility could result in penalties, loss of good standing, or even dissolution.
For foreign-owned companies, choosing a reliable registered agent is essential. Look for services that prioritize dependability, offer electronic delivery options, and provide strong customer support. Many professional agents offer systems designed to manage compliance across multiple states, reducing the risk of missed deadlines or important notices.
Recordkeeping
Keeping accurate records is essential for staying compliant with tax regulations. Detailed documentation of your business activities supports the accuracy of your federal income tax returns and ensures that records are readily available if you're audited.
Record Retention Requirements
The IRS requires businesses to hold onto key documents like receipts, contracts, invoices, financial statements, and bank records for at least three years. However, a safer approach is to keep these records for 5–7 years. For foreign-owned companies, the IRS mandates retaining records of reportable transactions with related parties for a minimum of five years. Additionally, reporting corporations must maintain permanent books and records, as outlined in section 6001, to verify the accuracy of their federal income tax returns. This includes documentation related to transactions with related parties.
Having well-organized records not only simplifies audits but also supports accurate tax filings, helping your business maintain compliance and good standing.

Sales Tax Nexus and State Registration Requirements
Navigating sales tax compliance can be a daunting task for foreign-owned U.S. companies. Unlike federal taxes, sales tax operates at the state level, with over 9,000 different jurisdictions across the country, each with its own rules and regulations. Knowing when and where your business has sales tax obligations is essential to staying compliant and avoiding hefty penalties.
Understanding Sales Tax Nexus
Sales tax nexus refers to the connection between a business and a state that triggers the requirement to register, collect, and remit sales tax. Geoff Christian, Managing Director at CBIZ MHM, explains:
"Nexus is the connection or 'minimum link' between a taxpayer and a state that requires the taxpayer to register, collect, and remit sales tax to the state".
For many foreign companies, sales tax obligations can arise unexpectedly - even if they don’t owe federal income tax. This is because state nexus standards are much easier to meet than the federal thresholds for income tax. The 2018 Supreme Court case South Dakota v. Wayfair, Inc. reshaped the sales tax landscape by removing the need for a physical presence to establish nexus.
Here are the four main types of nexus that can create sales tax obligations:
- Physical Nexus: A tangible presence in a state, such as an office, warehouse, employees, or even attending trade shows.
- Economic Nexus: Based on sales volume or transaction count in a state, regardless of physical presence. The Wayfair decision validated this standard.
- Affiliate Nexus: Relationships with other entities that have a physical presence in a state.
- Click-Through Nexus: Paying commissions to third-party sellers or referral agents within a state.
Economic nexus thresholds vary by state, but many follow the $100,000 in sales or 200 transactions standard set by Wayfair. However, some states have their own thresholds:
| State | Sales Threshold | Transaction Threshold |
|---|---|---|
| Alabama | $250,000 | None |
| California | $500,000 | None |
| Mississippi | $250,000 | None |
| New York | $500,000 | 100 transactions |
| Texas | $500,000 | None |
As of March 2025, every state with a sales tax has adopted economic nexus rules similar to South Dakota’s. However, five states - New Hampshire, Oregon, Montana, Alaska, and Delaware - do not impose statewide sales taxes. That said, some local jurisdictions in Alaska may still levy their own taxes.
State Registration and Filing Requirements
If your business has nexus in a state, the next step is registering for a sales tax permit with that state’s department of revenue. Often, this involves foreign qualification with the secretary of state, particularly if your activities are considered "doing business" in that state.
The registration process typically requires you to provide details such as your Employer Identification Number (EIN), business structure, and projected sales volume. Since each state has its own registration portal and requirements, it’s crucial to understand the specifics for every jurisdiction where you operate.
After registering, you’ll need to collect sales tax on taxable transactions and file returns periodically. The filing frequency usually depends on your sales volume and varies by state. Keeping accurate records is key - track sales by state, document taxes collected, and maintain detailed transaction records. These records are critical for filing returns and can be invaluable during audits, which states pursue aggressively - even with foreign businesses.
Some states offer Voluntary Disclosure Programs or Tax Amnesty programs to help businesses address past nexus obligations. These programs often reduce penalties and limit the lookback period for unpaid taxes, provided companies voluntarily register and settle their outstanding liabilities.
Because managing sales tax compliance across multiple states can be overwhelming, many foreign-owned companies rely on sophisticated compliance systems to avoid legal and financial risks. Regularly reviewing your sales activities is essential, as economic nexus thresholds can be reached quickly - especially for growing businesses - and state standards frequently change.
This structured approach to registration and compliance ensures your business stays ahead of potential challenges.
Compliance Tools and Support Services
Navigating federal and state compliance requirements can be daunting, especially for foreign-owned U.S. companies. From strict deadlines to intricate tax forms, the process often feels overwhelming. This is where specialized compliance tools and professional support services step in, simplifying the workload and ensuring everything stays on track.

When to Get Professional Help
Sometimes, managing compliance internally becomes too much to handle. Knowing when to seek professional help can save your business from costly mistakes.
- Multi-state operations: If your business operates across multiple states, compliance gets tricky. Each state has its own filing rules, deadlines, and penalties, making it nearly impossible to manage everything manually.
- High sales volume: Businesses that meet economic nexus thresholds in multiple states face significant sales tax compliance burdens. Professional help can ease the administrative load.
- First-time filers: Filing IRS Form 5472 or other complex forms for the first time can feel like navigating a maze. Professional assistance ensures accuracy and helps establish good filing habits.
- Changing business structures: If you're restructuring, adding partners, or converting your entity type, compliance needs can shift dramatically. Professional guidance helps you stay ahead of these changes.
- Audits or missed deadlines: If tax authorities contact you or you’ve fallen behind on filings, professionals can assist with voluntary disclosure programs or prepare responses to minimize penalties.
Investing in professional compliance support is often less expensive than the penalties, interest, and legal headaches that can arise from mistakes. For foreign-owned U.S. companies, getting the right help early on is a smart way to protect your business and ensure smooth operations.
Key Takeaways for Compliance Success
Compliance isn't just about avoiding penalties - it’s about safeguarding your business and ensuring its long-term stability. For example, violating IRS Form 5472 requirements can cost you at least $25,000 per year. On top of that, missing state deadlines can lead to severe consequences like administrative dissolution or losing your good standing status.
The foundation of effective compliance lies in understanding that federal and state requirements operate separately. Recognizing this distinction is key to developing a smooth compliance strategy.
One essential practice is keeping your records organized year-round. This makes filings and audits much easier to handle. Plus, electronic filing is now mandatory for most federal forms, including Form 5472.
Sales tax nexus is another area that often trips up foreign-owned companies. If your business surpasses $100,000 in sales or completes 200 transactions in a single state, you’re typically required to register and file regular returns. These thresholds can sneak up on you, particularly as your business grows, so regular tracking is crucial.
Beneficial Ownership Information (BOI) reporting remains critical for foreign entities, even as domestic companies are exempt starting in 2025. Missing this filing can lead to increased scrutiny and penalties, making it vital to stay on top of these evolving regulations.
The most successful companies treat compliance as a year-round priority, not a last-minute scramble. They rely on tools to track deadlines, maintain organized records, and seek professional advice when navigating multi-state operations or adapting to regulatory changes. By embedding compliance into your routine, you can shift it from being a burden to a strategic advantage - allowing you to focus on growth while staying in good standing.
As compliance rules and penalties continue to change, staying informed and adjusting your approach ensures your business remains protected and ready to thrive in the U.S. market.
FAQs
What happens if a foreign-owned U.S. company misses the deadline for filing IRS Form 5472?
Failing to submit IRS Form 5472 on time comes with a hefty $25,000 penalty for each instance of non-compliance. If the delay continues, further fines can accumulate for every month the form remains incomplete or unfiled.
To steer clear of these steep penalties, foreign-owned U.S. companies need to stay on top of filing deadlines and ensure all the required details are accurate and fully completed.
What are economic nexus laws, and how do they impact the sales tax responsibilities of foreign-owned companies operating in multiple US states?
Economic nexus laws mandate that businesses - including those owned by foreign entities - must register, collect, and remit sales tax in a state once they exceed certain sales or transaction thresholds. What’s unique about these laws is that they apply even if the business doesn’t have a physical location in the state. These thresholds differ from state to state and are typically determined by annual revenue or the number of transactions with customers in that state.
For foreign-owned companies operating across multiple states, keeping a close eye on sales activity is essential to identify where these rules come into play. Ignoring or failing to comply with economic nexus laws can lead to penalties, interest charges, or even losing good standing with state tax authorities. Understanding the specific requirements for each state and staying ahead of these obligations can help businesses avoid unnecessary headaches and ensure compliance.
Why do foreign-owned U.S. companies need to have a registered agent in every state they operate in?
A registered agent plays a key role in helping foreign-owned U.S. companies comply with state laws. They serve as the official recipient for critical legal documents, such as lawsuits or government notices, ensuring your business doesn’t miss anything important. Plus, having a registered agent in every state where your company operates helps maintain good standing with state authorities and streamlines communication with government agencies.
By appointing a registered agent, you keep your business organized, responsive, and aligned with all legal requirements.
