How to File US Business Taxes as a Non-Resident Owner in 2026: Form 5472, 1120, and Penalties Explained

But here is what nobody tells you at the formation stage.

The moment you register a business entity in the United States — whether an LLC in Wyoming, a C-Corporation in Delaware, or any other structure — you have created a legal obligation with the IRS that does not care whether you have ever set foot on American soil.

The Internal Revenue Service requires foreign-owned US businesses to file specific information returns every year. These are not optional filings. They are not only required when you earn income. They are mandatory compliance documents that must be filed on time regardless of whether your business made a single dollar.

The penalties for non-compliance are not gentle reminders. A single missed Form 5472 filing can trigger a $25,000 penalty — per form, per year. For a business owner who has gone three or four years without filing, the accumulated penalties can exceed the value of the business itself.

Understanding your US tax filing obligations as a non-resident owner is not just good practice. In 2026, with IRS enforcement of foreign-owned business compliance at its most aggressive level in decades, it is essential for protecting everything you have built.

The Two Most Important Forms: 5472 and 1120

What Is Form 5472?

Form 5472 — officially titled Information Return of a 25% Foreign-Owned U.S. Corporation or a Foreign Corporation Engaged in a U.S. Trade or Business — is the primary compliance document the IRS uses to track transactions between US businesses and their foreign owners.

If you are a non-resident who owns 25 percent or more of a US corporation or single-member LLC, Form 5472 is almost certainly required for your business every year you have reportable transactions — which, for most business owners, means every year the business exists.

Form 5472 is not a tax payment form. It is an information return. You are not writing a check with it — you are telling the IRS who owns the business, who the related foreign parties are, and what financial transactions occurred between them during the tax year.

What Is Form 1120?

Form 1120 is the US Corporation Income Tax Return. For foreign-owned single-member LLCs — which are disregarded entities for tax purposes — the IRS requires a pro forma Form 1120 to be filed alongside Form 5472. This pro forma 1120 is not a full corporate tax return. It is a shell filing that serves as the vehicle for attaching and submitting Form 5472.

For actual C-Corporations — whether domestic or foreign-owned — Form 1120 is the full annual corporate income tax return reporting income, deductions, credits, and tax liability.

Why Foreign-Owned LLCs File Like Corporations

This is the point that confuses most foreign business owners and their advisors.

A single-member LLC in the United States is normally a disregarded entity — meaning it has no separate tax existence from its owner. But when that owner is a foreign person or foreign entity, the IRS treats the LLC differently. Treasury Regulation 1.6038A-1 requires foreign-owned single-member LLCs to be treated as domestic corporations for the specific purpose of filing Form 5472 — even though the LLC remains a disregarded entity for all other tax purposes.

This creates a unique filing requirement that catches many foreign owners completely off guard.

Penalties for Missing Form 5472

The penalty for failing to file a required Form 5472 — or for filing it with incomplete or incorrect information — is $25,000 per form per tax year. If the IRS issues notice of the filing requirement and the taxpayer still fails to file within 90 days, an additional $25,000 penalty accrues for each subsequent 30-day period of continued failure.

These penalties can be assessed even if the business owed zero tax for the year. They are information return penalties — tied to the act of not reporting, not to the existence of tax liability.

Filing Requirements by Entity Type

Foreign-Owned Single-Member LLC

A foreign-owned single-member LLC must file Form 5472 attached to a pro forma Form 1120 annually with the IRS. The filing is due on April 15 for calendar-year taxpayers, with an automatic six-month extension available to October 15 by filing Form 7004.

Foreign-Owned Multi-Member LLC

A foreign-owned multi-member LLC is taxed as a partnership by default. It files Form 1065 — the US Return of Partnership Income — annually. If a foreign person owns 25 percent or more of the LLC, Form 8865 — Return of U.S. Persons With Respect to Certain Foreign Partnerships — may also be required depending on the specific ownership structure. Form 5472 generally does not apply to partnerships.

Foreign-Owned C-Corporation

A foreign-owned C-Corporation files a full Form 1120 annually reporting all income, deductions, and tax liability. If a foreign person owns 25 percent or more of the corporation’s stock, Form 5472 is also required for each year with reportable transactions. The corporation pays US federal income tax at the flat 21 percent corporate rate on its taxable income.

Foreign-Owned S-Corporation

S-Corporations in the United States cannot have non-resident alien shareholders. If a foreign national owns shares in an S-Corporation, the S election is technically terminated — converting the entity to a C-Corporation from the date the ineligible shareholder acquired ownership. Many foreign business owners who purchase existing S-Corporations are unaware of this issue until it becomes a significant tax problem.

LLC Taxed as C-Corp

A foreign-owned LLC can elect to be taxed as a C-Corporation by filing Form 8832 — Entity Classification Election. Once this election is made, the LLC files Form 1120 as its annual tax return and is subject to the 21 percent corporate income tax rate. Form 5472 is also required if the 25 percent foreign ownership threshold is met and reportable transactions exist.

Form 5472 Line-by-Line Walkthrough

Part I: Reporting Corporation Information

Part I identifies the US reporting corporation — your US LLC or corporation. You enter the entity’s name exactly as registered, the Employer Identification Number, the address, the tax year dates, the total assets at year end, and the principal business activity code. If the entity is a foreign-owned single-member LLC filing a pro forma 1120, you note this in the applicable checkbox.

Part II: 25% Foreign Shareholder Information

Part II identifies each foreign person who owns 25 percent or more of the reporting corporation’s stock or interest. You provide the foreign owner’s name, country of residence, US taxpayer identification number if one exists, foreign taxpayer identification number, and ownership percentage. If there are multiple 25 percent foreign shareholders, a separate Form 5472 must be filed for each one.

Part III: Related Party Information

Part III identifies any other related parties — foreign or domestic — that had transactions with the reporting corporation during the tax year. Related parties include entities controlled by the same foreign owner, family members of the foreign owner, and any other persons with a controlled relationship to the reporting corporation as defined under IRC Section 482.

Part IV: Monetary Transactions

Part IV reports monetary transactions between the reporting corporation and the related party identified in Part II. These include sales of inventory, services rendered, commissions, rents, royalties, interest payments, and management fees. Each category of transaction is entered as a separate dollar amount.

Part V: Reportable Transactions with Foreign Owner

Part V is specifically required when the related party is the 25 percent foreign shareholder identified in Part II. This part captures capital contributions made by the foreign owner to the US entity, distributions made from the US entity to the foreign owner, loans between the parties, and payments for property or services. For many foreign-owned LLCs, the most commonly reported items are capital contributions — money the owner transferred to the business — and distributions taken from the business.

Part VI: Additional Information

Part VI asks several yes-or-no questions about the reporting corporation’s activities, transactions, and relationships during the tax year. These include whether the entity had any transactions subject to IRC Section 482 cost-sharing arrangements, whether any base erosion payments were made, and whether the corporation was part of a consolidated group. Most simple foreign-owned LLCs answer no to all Part VI questions.

Form 1120 Pro Forma for Foreign-Owned LLCs

Page 1 Header

The pro forma 1120 for a foreign-owned single-member LLC uses the same form as a regular corporate tax return but is completed minimally. At the top, you enter the LLC’s legal name, EIN, address, and date of incorporation — using the date the LLC was formed.

Box A through E

Box A requests the date incorporated. Box B requests the total assets at the end of the tax year — taken from the LLC’s balance sheet. Box C requests the principal business activity. Box D requests the principal product or service. Box E requests an accounting method — most LLCs use the cash method.

Income Statement Lines

For a pro forma filing by a disregarded-entity LLC, the income statement lines are typically left blank or completed with zeros. The form is being filed as a vehicle to attach Form 5472 — not to report and calculate corporate income tax liability for the LLC itself.

Schedule Attachments

Form 5472 is attached to the pro forma 1120 as the primary schedule. Any other required schedules — such as Schedule M-1 reconciling book and tax income — are typically not completed for a pure pro forma filing.

Signature Section

The pro forma 1120 must be signed and dated by an officer of the corporation or, for LLCs, by the member or authorised manager. A paid preparer must also complete the preparer section if a CPA or tax professional prepared the return.

Deadlines: When You Must File

Federal Tax Deadlines

For calendar-year taxpayers — those whose tax year runs from January 1 to December 31 — the standard filing deadline for Form 5472 attached to a pro forma Form 1120 is April 15 of the following year. For corporations filing a full Form 1120, the deadline is also April 15 for calendar-year taxpayers.

For fiscal-year taxpayers — those using a tax year that does not end on December 31 — the filing deadline is the 15th day of the fourth month following the close of the tax year.

State Tax Deadlines

State filing deadlines vary by state and entity type. Many states follow the federal deadline of April 15 but others use different dates. California, for example, requires LLCs to pay an annual franchise tax of $800 by the 15th day of the fourth month of the tax year — meaning a new LLC formed in California can owe this fee very soon after formation. Always verify your specific state’s deadlines with a qualified tax professional.

How to Request an Extension

Foreign-owned LLCs and corporations can request an automatic six-month extension of time to file their federal return by submitting Form 7004 by the original due date. The extension extends the time to file — not the time to pay any taxes owed. If the business has a tax liability, estimated payments should be made by the original deadline to avoid late payment penalties and interest.

Common Mistakes Non-Resident Owners Make

Mistake 1: Not Filing Form 5472 at All

The most costly mistake by far. Many foreign LLC owners are simply unaware that Form 5472 exists and that their single-member LLC triggers this filing requirement every year.

Mistake 2: Filing Wrong Entity Type

Treating a disregarded LLC the same as a partnership or assuming no filing is needed because the LLC made no profit. Entity type determines which forms are required — understanding your specific structure is foundational.

Mistake 3: Mixing Personal and Business Transactions

Using the US business bank account for personal expenses — or vice versa — creates transactions that must be reported on Form 5472 and can create tax liability where none would otherwise exist. Strict separation of business and personal finances is essential.

Mistake 4: Missing Capital Contribution Reporting

Every time a foreign owner transfers money to their US LLC — even to cover operating expenses — that transfer is a capital contribution that must be reported on Form 5472. Many owners do not realise that routine fund transfers require formal reporting.

Mistake 5: Incorrect Foreign Address Format

The IRS has specific formatting requirements for foreign addresses on Form 5472. Using the wrong format or omitting required country codes and postal codes can cause the form to be rejected or flagged for review.

Mistake 6: Filing Late Without Extension

Filing after the deadline without having submitted a timely extension request exposes the business to the full $25,000 penalty even if the late filing is only a few days overdue.

Mistake 7: Wrong Tax Year

Misidentifying the tax year covered by the filing — particularly for newly formed entities or businesses changing their fiscal year — creates discrepancies in IRS records that can trigger notices and penalties.

Mistake 8: Skipping BOI Report

The Corporate Transparency Act’s Beneficial Ownership Information reporting requirement — effective 2024 — requires most US LLCs and corporations to file a BOI report with FinCEN identifying their beneficial owners. Failure to file carries separate penalties of up to $591 per day.

Mistake 9: Not Maintaining Records

Form 5472 reporting must be supported by contemporaneous records — bank statements, contracts, invoices, and other documentation of reported transactions. In the event of an IRS examination, inability to produce supporting records transforms a manageable audit into a potential penalty assessment.

Mistake 10: DIY Form 5472 Filing

The complexity and high penalty exposure of Form 5472 make it one of the least appropriate tax forms for self-preparation by non-specialists. A single error can trigger a $25,000 penalty that dwarfs the cost of professional preparation many times over.

 How to Fix Past Filing Errors

Step 1: Acknowledge the Problem

The worst response to a discovered filing gap is to hope the IRS does not notice. The IRS has significantly improved its data matching and foreign ownership detection capabilities in recent years. Proactive correction is always less costly than waiting for IRS contact.

Step 2: Hire an Experienced Cross-Border CPA

Before taking any action, engage a CPA with specific expertise in foreign-owned US business tax compliance. This is not work for a general practitioner.

Step 3: File Late Returns

File all missing Form 5472 and Form 1120 pro forma returns as soon as possible. Late filing stops the penalty clock from continuing to accumulate.

Step 4: Request Penalty Abatement

The IRS offers several penalty relief programmes. First-time penalty abatement is available to taxpayers with a clean compliance history who request relief. Reasonable cause abatement is available when the failure to file was due to circumstances beyond the taxpayer’s control. A qualified CPA can assess which relief programme applies to your situation and prepare a compelling abatement request.

Step 5: Respond to IRS Notices Promptly

If you receive an IRS notice regarding missing filings or penalty assessments, respond within the specified timeframe. Failure to respond escalates the situation and reduces your options for penalty reduction.

Step 6: Set Up Annual Compliance Going Forward

After catching up on past filings, establish a systematic annual compliance process to ensure all future filings are submitted accurately and on time.

Cost of Catch-Up Filings

Expect to pay $500 to $2,500 per year of catch-up Form 5472 and pro forma 1120 preparation, depending on the complexity of your situation and the number of reportable transactions. This is significantly less than the $25,000 penalty per year of non-filing.

 Tax Liability for Non-Resident LLC Owners

When You Owe US Federal Income Tax

A foreign-owned single-member LLC that is a disregarded entity does not itself pay US federal income tax. The tax liability — if any — flows through to the foreign owner. The foreign owner owes US tax only on income that is effectively connected with a US trade or business — known as ECI — or on US-source income subject to withholding such as dividends, interest, rents, and royalties.

When You Owe Zero US Tax

Many foreign-owned US LLCs are used for activities that do not create ECI for the foreign owner — for example, holding US securities, operating an e-commerce business that ships from outside the US, or providing services entirely outside the United States. In these situations, the LLC may have no US federal income tax liability while still having a Form 5472 filing obligation.

Common Scenarios for Foreign-Owned LLCs

A Nigerian entrepreneur operating a dropshipping business through a US LLC may have no US tax liability if the business activity — supplier relationships, customer service, and fulfillment — occurs entirely outside the United States. The same owner who opens a warehouse in Texas or hires US employees creates ECI and triggers US income tax obligation.

State Tax Considerations

State tax obligations are separate from federal obligations and vary significantly. An LLC registered in Wyoming pays no state income tax — Wyoming has none. The same LLC operating in California — even through economic presence without physical location — may trigger California franchise tax and income tax obligations.

 US Tax Treaty Benefits for Non-Resident Owners

Treaty Countries vs Non-Treaty Countries

The United States has income tax treaties with approximately 70 countries as of 2026. These treaties modify the default US tax rules for residents of treaty countries — potentially reducing or eliminating withholding taxes on certain US-source income.

How Treaty Benefits Reduce Withholding

Without a treaty, the default US withholding tax rate on dividends paid to foreign shareholders is 30 percent. A tax treaty may reduce this rate to 15 percent, 5 percent, or even zero depending on the specific treaty provisions and the ownership percentage of the shareholder.

Claiming Treaty Benefits

Treaty benefits are claimed on Form W-8BEN — Certificate of Foreign Status of Beneficial Owner — submitted to the withholding agent. For business income, Form 8833 — Treaty-Based Return Position Disclosure — may be required when taking a treaty position that reduces US tax on Form 1040-NR or other tax returns.

Treaty Considerations for Common Countries

Nigeria does not currently have an income tax treaty with the United States — meaning Nigerian business owners receive no treaty-based rate reductions on US-source income. The UK, Germany, Canada, India, and most Western European countries do have treaties that provide meaningful withholding rate reductions for eligible residents.

FBAR and FATCA for Foreign-Owned Business Owners

What Is FBAR

The Foreign Bank Account Report — FinCEN Form 114 — is required to be filed annually by US persons — including US entities — that have a financial interest in or signature authority over foreign financial accounts with an aggregate value exceeding $10,000 at any point during the calendar year.

What Is FATCA

The Foreign Account Tax Compliance Act requires US taxpayers with specified foreign financial assets exceeding applicable thresholds to report those assets on Form 8938 attached to their annual tax return. FATCA applies primarily to US persons — citizens, permanent residents, and resident aliens — rather than to foreign-owned US entities specifically.

When These Apply to Non-Resident Business Owners

FBAR is a US person obligation. A foreign-owned US LLC is itself a US entity — meaning the LLC could have FBAR obligations if it holds foreign accounts. The foreign owner as an individual may also have FBAR obligations depending on their US tax status. These requirements are separate from and in addition to Form 5472 obligations.

 Working with Cross-Border CPAs

What to Expect From a Cross-Border CPA

A qualified cross-border CPA provides analysis of your US filing obligations based on your specific entity structure and activities, preparation of Form 5472, pro forma 1120, and any other required federal and state filings, ongoing advisory services on structuring transactions to minimise tax exposure, and representation before the IRS in the event of notices or audits.

Top Cross-Border CPAs for Foreign-Owned Businesses

Firms with established foreign-owned US business practices include Greenback Tax Services, Bright!Tax, US Tax Help, and numerous regional accounting firms with international departments. When selecting a CPA, verify their specific experience with Form 5472 and foreign-owned LLC compliance — not just general international tax experience.

Questions to Ask Your CPA

Ask specifically how many foreign-owned LLC Form 5472 returns they prepare annually, whether they have experience with clients from your home country, what their process is for collecting information from clients in different time zones, and whether they carry professional liability insurance.

What to Prepare for Your CPA

To work efficiently with your CPA you should have your LLC formation documents, operating agreement, EIN confirmation letter, annual bank statements, records of all transfers between yourself and the LLC, records of any other transactions with related parties, and any prior year tax filings or IRS correspondence.

 State Tax Compliance for Multi-State Operations

State Income Tax Obligations

A foreign-owned LLC that has employees, offices, warehouse space, or significant sales in a US state may create nexus — a taxable presence — in that state triggering state income tax filing obligations. Each state has its own nexus standards and these have expanded significantly in the e-commerce era.

Sales Tax Compliance

The Supreme Court’s 2018 South Dakota v. Wayfair decision established that states can impose sales tax collection obligations on sellers with significant economic presence — regardless of physical location. Foreign-owned businesses selling products to US customers in 2026 must understand their sales tax obligations in states where they have economic nexus.

Franchise Tax Obligations

Several states impose franchise taxes on entities formed or registered in the state regardless of whether they have taxable income. California’s $800 annual minimum franchise tax applies to all LLCs registered in California. Delaware charges an annual franchise tax on all corporations incorporated in the state.

Common Multi-State Mistakes

Assuming that forming an LLC in a no-income-tax state like Wyoming or Nevada eliminates state tax obligations entirely is one of the most expensive mistakes in foreign-owned business tax planning. State tax obligations are determined by where you do business — not where you are incorporated.

 Penalties Beyond Form 5472

Form 1120 Late Filing Penalty

Corporations and LLCs required to file Form 1120 that miss the deadline face a penalty of 5 percent of the unpaid tax per month or partial month the return is late, up to a maximum of 25 percent. If the return is more than 60 days late, the minimum penalty is the lesser of $450 or 100 percent of the tax due.

Form 1099 Late Filing Penalties

Businesses that pay US contractors $600 or more during the year must issue Form 1099-NEC. Late or missing 1099 forms carry penalties ranging from $60 to $660 per form depending on the degree of lateness and whether intentional disregard is involved.

Payroll Tax Penalties

Foreign-owned businesses with US employees must collect and remit federal payroll taxes — Social Security, Medicare, and federal income tax withholding. Failure to deposit payroll taxes on time triggers Trust Fund penalties that can be assessed personally against business owners and responsible parties.

FBAR Penalties

Non-willful failure to file an FBAR carries penalties up to $10,000 per violation — with each account for each year constituting a separate violation. Willful failure to file carries penalties up to the greater of $100,000 or 50 percent of the account balance per violation — and can also result in criminal prosecution.

State Tax Penalties

State tax penalties vary by state but commonly include late filing penalties of 5 to 25 percent of the tax due and late payment penalties plus interest at rates that vary by jurisdiction.

 Scam Warnings: How to Avoid Tax Fraud

Red Flag 1: Promises of Zero US Tax With No Analysis

Any service provider who tells you that your US LLC will never owe US tax — without first conducting a thorough analysis of your business activities, residency status, and income sources — is either incompetent or dishonest. Whether you owe US tax depends on specific facts. No honest professional promises an outcome before reviewing those facts.

Red Flag 2: Fake IRS Phone Calls

The IRS does not initiate contact with taxpayers by phone, email, or text message. IRS contact begins with a formal mailed notice to your registered address. Anyone calling you claiming to be the IRS and demanding immediate payment is a scammer.

Red Flag 3: Cheap Form 5472 Services

Form 5472 preparation for $50 or $100 is a red flag. The complexity of this filing and the associated penalty exposure require experienced professional preparation. Artificially cheap services frequently result in incorrect or incomplete filings that trigger the very penalties they were supposed to prevent.

Red Flag 4: Fake Tax Software From Unknown Sites

Only use IRS-authorised e-file providers and recognised tax software platforms for any US tax-related filings. Software from unknown websites may steal your personal and financial information or produce incorrect filings.

Red Flag 5: Promises to Make Past Filings Disappear

No legitimate tax professional can make past filing obligations disappear. They can help you file late returns, pursue penalty abatement, and achieve the most favourable resolution possible — but the obligation to file existed and must be addressed through legitimate channels.

Red Flag 6: Demands for Cash or Crypto Payment

The IRS does not accept payment in cryptocurrency, gift cards, or wire transfers to personal accounts. Any demand for tax payment through these methods is a scam.

Red Flag 7: Aggressive Cold Outreach

Legitimate CPAs and tax firms do not send unsolicited messages promising to solve your US tax problems for a fee paid immediately. Be extremely cautious of cold outreach through social media, WhatsApp, or email.

Verification Steps

Verify any CPA’s credentials through the IRS Directory of Federal Tax Return Preparers at irs.gov/taxpros. Verify any enrolled agent’s status through the IRS website. Check professional association membership through the AICPA or your state’s CPA society. Always get a written engagement letter before paying any fees.

 Government and Industry Resources

Frequently Asked Questions

Do I need to file Form 5472 if my LLC made no money?
Yes. Form 5472 is required for any year in which your foreign-owned LLC had reportable transactions with its foreign owner — including capital contributions made to fund the business. Even if the LLC had zero revenue, money you transferred to the LLC to cover expenses constitutes a reportable transaction that triggers the Form 5472 requirement.

What is the penalty for not filing Form 5472?
The base penalty is $25,000 per form per tax year. If the IRS issues notice of the filing requirement and the taxpayer still fails to file within 90 days, an additional $25,000 penalty accrues for each additional 30-day period of non-filing. Penalties can accumulate to hundreds of thousands of dollars for multi-year non-compliance.

Do I need an EIN for my foreign-owned LLC?
Yes. Your US LLC must have an Employer Identification Number to file Form 5472 and the pro forma Form 1120. Non-residents without a Social Security Number apply for an EIN by submitting Form SS-4 to the IRS, typically by fax or mail, or through a designated third-party authorised representative.

Can I file Form 5472 electronically?
As of 2026, Form 5472 attached to a pro forma Form 1120 for a foreign-owned single-member LLC must be mailed to the IRS — electronic filing through standard e-file channels is not available for this specific filing type. Your CPA will mail the completed return to the IRS submission processing centre specified in the Form 1120 instructions.

Will the IRS know if I don’t file?
The IRS receives information from US banks, state formation agencies, and international information exchange agreements with foreign governments. The chance of remaining undetected while operating a US bank account — which requires an EIN — without filing required returns is significantly lower than most non-filers assume. Proactive compliance is always the superior strategy.

Does my Wyoming LLC pay Wyoming state tax?
Wyoming has no state income tax, making it a popular formation state for foreign owners. However, if your Wyoming LLC has nexus in other states through employees, sales, or physical presence, you may owe tax in those other states regardless of where the LLC is formed.

How do I know if my country has a tax treaty with the US?
The IRS maintains a complete list of US income tax treaties at irs.gov/businesses/international-businesses/united-states-income-tax-treaties-a-to-z. As of 2026, Nigeria does not have a tax treaty with the United States.

What happens if I dissolve my US LLC — do I still need to file?
Yes. You must file a final Form 5472 and pro forma Form 1120 for the year in which the LLC is dissolved, including all transactions up to the dissolution date. Failing to file final returns for a dissolved entity does not eliminate the filing obligation for years the entity existed.

 Final Thoughts: Your Non-Resident Tax Compliance Strategy

The Three Pillars of Foreign-Owned Tax Compliance

Successful long-term compliance for foreign-owned US businesses rests on three pillars. The first is accurate entity classification — understanding exactly what type of entity you have and which tax forms it requires. The second is transaction documentation — maintaining complete and organised records of all financial activity between you and your US entity throughout the year. The third is timely filing — submitting all required returns on or before their deadlines, with extensions filed when needed.

Your Annual Tax Compliance Calendar

January through March — gather all bank statements, transaction records, and supporting documentation for the prior tax year. Contact your CPA to initiate return preparation. March and April — review and sign completed Form 5472 and pro forma Form 1120. File or arrange for mailing by April 15. If not ready, file Form 7004 by April 15 to secure the extension to October 15. May through September — complete return preparation if on extension. File FBAR by April 15 with automatic extension available to October 15. October — file extended returns by October 15. December — review current year transactions and begin organising documentation for the coming filing season.

Your Action Steps for 2026

If you have a foreign-owned US LLC or corporation and have never filed Form 5472 — act immediately. Engage a cross-border CPA, identify the years for which filings are required, prepare and file all missing returns, and request penalty abatement. The cost of catching up is dramatically less than the accumulated penalties of continued non-filing.

If you are current on your filings — use this year to strengthen your record-keeping systems, confirm your state compliance in every state where your business operates, and review whether your entity structure continues to serve your business goals.

If you are forming a new US entity in 2026 — build compliance into your business plan from day one. Set up separate business banking, maintain clean transaction records from the moment of formation, and engage a qualified CPA before your first filing deadline arrives.

The Bigger Picture

Foreign ownership of US businesses is a genuine opportunity — one that thousands of entrepreneurs from Nigeria, India, the UK, Brazil, Canada, and dozens of other countries are using to build real wealth and global business presence.

The IRS requirements are not designed to punish foreign owners. They are designed to maintain the transparency and integrity of the US tax system. Understanding and meeting these requirements is simply the cost of accessing one of the world’s most powerful business platforms.

Do it right. Do it on time. And build the global business you came here to build — with a clean compliance record that protects everything you have created.
