Form 5472 & 1120 Pro Forma Filing for Foreign-Owned LLCs

Foreign-owned single-member LLCs, which are treated as disregarded entities, must file Form 5472 along with Form 1120 Pro Forma whenever they have reportable transactions with foreign related parties. Because most tax software does not support these forms, we often see serious mistakes in DIY filings. As a result, many owners face the $25,000 Form 5472 penalty. Fortunately, our CPAs have completed more than 500 filings with a strong record of penalty-free compliance.

"What's the difference between Form 1120 Pro Forma and regular Form 1120?"

Form 1120 Pro Forma is a simplified information return for disregarded entities. In other words, it reports activity but does not calculate tax. By contrast, the full Form 1120 is used by C-Corporations to calculate corporate tax liability. The Pro Forma version is filed only to attach Form 5472. Importantly, the $25,000 penalty applies to Form 5472, not the 1120 Pro Forma.

Partnership Withholding Tax - Form 8804 & 8805

Partnerships and multi-member LLCs with foreign partners must follow specific IRS withholding requirements. In these situations, the partnership must withhold tax on each foreign partner’s distributive share of effectively connected income (ECI), file Form 8804 for quarterly payments, and issue Form 8805 to every foreign partner each year. If these steps are missed, penalties can reach 5% of the unpaid tax per month, up to a 25% maximum, and the partnership may still be responsible for any unpaid withholding.

"I thought partnerships don't pay tax - why do we need to withhold?"

Partnerships do not pay tax at the entity level. However, they must withhold on the foreign partner’s share of ECI under IRC Section 1446. This rule exists because foreign partners must meet their U.S. tax obligations. If withholding is not done, the partnership becomes liable for the tax as well as the related penalties and interest.

Foreign-Owned Corporation - Form 1120 & 5472

Foreign-owned C-Corporations must file both a full Form 1120 corporate tax return and Form 5472 when there are reportable transactions with related foreign persons. Because the IRS imposes different penalties for each form, Form 1120 carries percentage-based penalties of 5% per month (up to 25% of unpaid tax), while Form 5472 carries a flat $25,000 penalty for noncompliance. In addition, these filings often require careful transfer pricing analysis, foreign tax credit calculations, and dividend withholding planning

"Why does a corporation need both Form 1120 and Form 5472?"

Form 1120 Pro Forma is used only by disregarded entities and does not calculate tax. By contrast, the full Form 1120 is required for corporations to compute their taxable income. The Pro Forma version exists solely to attach Form 5472. Importantly, the $25,000 penalty applies to Form 5472, not the 1120 Pro Forma

ITIN Application & Renewal Services

Foreign individuals without a Social Security Number need an ITIN (Individual Taxpayer Identification Number) to file U.S. tax returns, open bank accounts, and comply with reporting requirements. We handle the entire ITIN application and renewal process, including document certification.

"Can't I just apply for an ITIN myself online?"

No – ITINs require mailing original documents or certified copies to the IRS, which can take 7-11 weeks. We’re IRS-authorized Certifying Acceptance Agents (CAA), so we can certify your documents without you mailing originals, and we ensure your application is complete to avoid rejections and delays.

Do I need to file Form 5472 for my foreign-owned LLC?

Yes, if you’re a foreign person who owns 25% or more of a US LLC (disregarded entity), you must file Form 5472 annually. This includes single-member LLCs owned by foreign individuals or entities. The penalty for not filing is $25,000 per form per year, making professional compliance essential.

💡 Do I need Form 5472 AND Form 1120 Pro Forma?

Yes. If you are a foreign person who owns 25% or more of a U.S. LLC, you must file Form 5472 every year. This filing applies to all foreign-owned single-member LLCs, regardless of whether the owner is an individual or a foreign entity. In addition, failing to file can result in a $25,000 penalty per year, which is why professional support is strongly recommended. Read guide →

🗺️ Which state is best for my foreign-owned LLC?

There is no single best state for every foreign-owned LLC. Many online businesses choose Wyoming because it offers lower annual costs and strong privacy rules. Meanwhile, venture-backed startups commonly select Delaware due to its legal and investor-friendly structure. However, if your business has physical operations, employees, or property in a particular state, you may need to register there regardless of where you form the LLC.. See detailed state comparison →

🆔 Do I need an ITIN to file Form 5472?

Foreign individuals without a Social Security Number need an ITIN to file any U.S. tax return, including returns with Form 5472. You can apply for an ITIN and file your return simultaneously. We’re IRS-authorized Certifying Acceptance Agents and can handle both. Learn about ITIN services →

⏱️ How long does ITIN application take?

IRS processing times typically range from 7–11 weeks during peak season (January through April) and 4–6 weeks during the rest of the year. When you work with a Certifying Acceptance Agent (CAA), you do not need to mail your original passport, which reduces risk and delays. In addition, rush support may be available for urgent situations. See timeline guide →

📋 What's the difference between 1120 Pro Forma vs full Form 1120?

Form 1120 Pro Forma is a simplified information return used by disregarded entities. It reports basic activity but does not calculate tax. In contrast, the full Form 1120 is the standard corporate tax return used by C-Corporations to compute tax liability. The Pro Forma version is filed only to serve as the attachment for Form 5472. See detailed comparison →

🤝 Do partnerships need Form 5472 or something else?

Partnerships with foreign partners do not file Form 5472. Instead, they must file Form 1065 for the partnership return, Form 8804 for withholding tax, and Form 8805 for each foreign partner. Because partnerships follow different IRS rules than disregarded entities or corporations, the filing requirements are not the same.. Read partnership guide →

💰 What is Form 8804 and who needs it?

Form 8804 reports the withholding tax that partnerships must pay on behalf of their foreign partners. It applies when the partnership has foreign partners with effectively connected income (ECI). The filing is required annually, and payments are made quarterly. If the partnership does not withhold properly, it may become responsible for the unpaid tax, along with interest and penalties. Read complete guide

📄 What is Form 8805?

Form 8805 is issued to each foreign partner and shows the partner’s share of income and the tax withheld under Section 1446. Foreign partners use this form to claim credit for the tax already withheld when they file their U.S. tax returns. Partnerships must provide Form 8805 to their foreign partners by March 15 each year. Learn more →

🏛️ Do foreign-owned corporations file Form 5472?

Yes. A foreign-owned C-Corporation with 25% or more foreign ownership must file both the full Form 1120 corporate tax return and Form 5472. Form 5472 is required whenever there are reportable transactions with related foreign persons. Both filings are mandatory, and each carries potential penalties if not submitted correctly. Read corporation guide →

💵 How much does Form 1120 Pro Forma preparation cost?

Form 1120 Pro Forma is included in our $450 Form 5472 package – they’re always filed together for disregarded entities. Full Form 1120 for corporations starts at $450. Partnership Form 1065 + 8804/8805 starts at $1,800. See all pricing →

⚠️ What are penalties for not filing Form 8804?

If a partnership fails to withhold and pay tax under Section 1446, it becomes liable for the unpaid tax as well as any interest. In addition, late filing penalties for Form 8804 can reach 5% of the unpaid tax per month, up to a 25% maximum. Read penalty guide →

🔍 How do I know if I'm a disregarded entity, partnership, or corporation?

A single-member LLC is treated as a disregarded entity by default, while a multi-member LLC is treated as a partnership. If the business is formally incorporated, it is treated as a corporation. However, you may elect a different tax classification using Form 8832. If you are unsure how your entity is classified, you can take our entity quiz for guidance. Take entity quiz →

❓ Form 5472 with no income - still required?

Yes. Filing Form 5472 is required based on reportable transactions with foreign related parties, not on the LLC’s income. This means you must still file even if the LLC generated no revenue. Transactions such as capital contributions, loans, or reimbursements all trigger the requirement. The $25,000 penalty applies regardless of income level. Read guide →

⏱️ When are these forms due?

ere are the standard IRS deadlines:

  • Form 5472 + Form 1120 Pro Forma: Due April 15 (or October 15 with an extension).

🇦🇪 UAE residents with US entities?

UAE residents often form U.S. LLCs to invoice global clients. Because there is no U.S.–UAE income tax treaty, proper structuring is essential to manage withholding and ECI exposure. Filing requirements still depend on the type of entity you form, so LLCs, partnerships, and corporations each have different obligations. Read UAE guide →

🏦 Help with US bank account for any entity?

Yes. We can help prepare bank-ready documentation for LLCs, partnerships, and corporations. This includes EIN confirmation letters, formation documents, ownership certifications, and introductions to banks that work with foreign investors. Read banking guide →

🗺️ Which entity type and state is best?

The best entity type and state depend on your specific situation. A single owner typically forms an LLC, while multiple owners may choose a partnership or corporation. All structures offer liability protection, but the tax implications are very different. Because of this, we review your circumstances and recommend the most suitable option. Read comparison →

🔧 Haven't been filing - what do I do?

You should act as soon as possible. We assist with voluntary compliance using reasonable-cause procedures for Forms 5472, 8804, 1120, and other required filings. In many cases, addressing the issue early improves your chances of receiving penalty relief. Because each form carries different risks, we recommend the appropriate remediation strategy based on your situation. Read remediation guide →

🎓 Can I file these forms myself?

It is technically possible to file these forms yourself, but it is not recommended. We often see significant errors in DIY submissions, especially for Form 5472 and Form 1120 Pro Forma. In addition, withholding calculations for Forms 8804 and 8805 can be complex, and Form 1120 is one of the most detailed corporate tax returns. Professional preparation typically costs far less than the penalties that may result from errors. Read DIY analysis →
