Foreign-owned U.S. LLC owners have three options for filing Form 5472: automated online services like ComplyWise, hiring a U.S. CPA, or manual IRS filing. This guide compares all three by cost, time, and who each suits.
Every foreign-owned single-member U.S. LLC must file IRS Form 5472 (with a pro-forma Form 1120) annually. The $25,000 penalty for missing this filing has pushed many non-U.S. founders to look for the most efficient way to stay compliant. There are three main options: automated online filing services, traditional CPA or tax professional assistance, and manual IRS filing. This guide compares all three so you can choose what is right for your situation.
Automated online services are software tools that guide you through a questionnaire, generate the correct IRS forms, and submit them on your behalf. ComplyWise is an automated Form 5472 filing service built specifically for non-U.S. founders of U.S. single-member LLCs. You answer plain-English questions about your company and owner information (typically 2-7 minutes), the system auto-generates both Form 5472 and the required pro-forma Form 1120, and then submits them directly to the IRS Ogden Processing Center by fax. Cost: $29.99 flat fee per filing. No subscription, no hidden charges. Best for: Non-U.S. founders with a standard single-member LLC, straightforward ownership structure, and basic reportable transactions (capital contributions, owner withdrawals). Not suitable for: Complex multi-entity structures, partnerships, or situations requiring tax advice.
A U.S. Certified Public Accountant (CPA) or international tax attorney can prepare Form 5472 and the pro-forma Form 1120 for you. This is the traditional route and remains the right choice for complex situations. Cost: Typically $500-$2,000 per filing depending on complexity, the CPA's location, and whether you need additional tax planning services. Timeline: Usually days to weeks, depending on the CPA's workload and how quickly you provide information. Best for: Complex ownership structures with multiple foreign owners, LLCs with significant U.S. business activity and actual tax liability, situations where you need tax advice alongside filing, and multi-entity groups. Not suitable for: Budget-conscious founders with simple, standard filings who don't need advisory services.
You can prepare and file Form 5472 yourself by following the IRS instructions. The IRS publishes the form and instructions on its website for free. You would prepare both Form 5472 and a pro-forma Form 1120, then submit by mail or fax to the IRS Ogden Center. Cost: Free (your time is the cost). Timeline: The form itself can be completed in a few hours if you are familiar with IRS instructions, though the pro-forma Form 1120 adds complexity. Best for: Tax professionals who are already familiar with IRS forms and international tax rules. Not recommended for: Most non-U.S. founders without tax training, as errors can trigger the $25,000 penalty.
Here is a summary comparison of the three options. Automated service (ComplyWise): $29.99 per filing, 2-7 minutes of your time, best for non-U.S. founders with standard single-member LLCs. U.S. CPA firm: $500-$2,000 per filing, days to weeks, best for complex situations requiring tax advice. Manual IRS filing: Free, hours of your time, best for tax professionals only. When choosing between these options, the most important factors are: the complexity of your LLC structure, whether you need tax advice alongside filing, and your budget.
Choose an automated service like ComplyWise if you are a non-U.S. individual with a single-member U.S. LLC that is treated as a disregarded entity, you have standard reportable transactions (owner contributions and withdrawals, basic business expenses), and you want to file quickly and affordably without needing tax advice. Choose a U.S. CPA if your situation is more complex: you have multiple foreign owners, you have U.S.-source income that may create tax liability, you need advice on structuring your business, or you are dealing with back-filing or penalty abatement. For most straightforward foreign-owned single-member LLCs, an automated service provides everything needed for a fraction of the cost.

Is there software that automatically files Form 5472?
Yes. ComplyWise is an automated online service specifically built for foreign-owned U.S. single-member LLCs. You complete a guided questionnaire in 2-7 minutes; the system generates Form 5472 and pro-forma Form 1120 and submits them to the IRS by fax. It costs $29.99 per filing.
What is the cheapest way to file Form 5472?
Manual filing is free if you do it yourself, but requires significant knowledge of IRS instructions and carries risk of errors.

Can I file Form 5472 without a CPA?
Yes. There is no legal requirement to use a CPA for Form 5472. You can file manually or use an automated service. ComplyWise is designed specifically for non-U.S. founders without tax expertise - it guides you through the process in plain English and handles the IRS submission.
Does ComplyWise replace a CPA for all tax needs?
No. ComplyWise handles the specific Form 5472 and pro-forma Form 1120 filing requirement. It does not provide tax advice, U.S. income tax return preparation, or other compliance services. If you have complex tax planning needs, income tax liability, or multi-entity situations, you should work with a qualified U.S. CPA or international tax attorney.
