Finding a Cross-Border Tax Professional: What to Look For, What to Ask, and What to Pay
Not every CPA understands foreign-owned LLCs. Here is how to find one who does: the qualifications that matter, 15 questions to ask in your first consultation, realistic price ranges, and red flags that signal the wrong fit.

Why a General CPA Is Not Enough
If you are a non-US person who owns a Wyoming LLC, your tax situation involves international tax rules, treaty considerations, informational return requirements (Form 5472), and potentially ITIN applications, multi-state sales tax, and foreign account reporting.
A general CPA who primarily serves domestic small businesses may not have experience with these specific requirements. Form 5472 is not part of most CPAs' regular workflow. Foreign-owned disregarded entities have unique filing rules that differ significantly from standard LLC taxation.
Hiring the wrong tax professional can result in missed filings, incorrect returns, and penalties that far exceed the cost of hiring the right professional from the start.
Three Types of Tax Professionals
Certified Public Accountant (CPA)
A CPA has passed the Uniform CPA Examination and met state licensing requirements. CPAs can prepare tax returns, represent you before the IRS, and provide tax advisory services.
When you need a CPA: For annual Form 5472 preparation, pro forma 1120 filing, multi-state sales tax returns, and general tax compliance.
Typical cost range: $150-500/hour, or $300-800 for annual Form 5472 filing as a fixed fee.
Enrolled Agent (EA)
An Enrolled Agent is a federally licensed tax practitioner who has passed the IRS Special Enrollment Examination or has former IRS employee experience. EAs can represent you before the IRS at all levels (audits, appeals, collections).
When you need an EA: For the same services as a CPA. EAs who specialize in international tax can handle Form 5472, ITIN applications, and IRS correspondence. EAs often charge less than CPAs for equivalent services.
Typical cost range: $100-350/hour, or $250-600 for annual Form 5472 filing.
Tax Attorney
A tax attorney holds a law degree (JD) and often an advanced tax law degree (LLM in Taxation). Tax attorneys can provide legal advice, represent you in Tax Court, and handle complex structural planning.
When you need a tax attorney: If you face IRS penalties requiring formal appeal, need to structure a complex multi-entity arrangement, have potential criminal tax exposure, or need treaty interpretation. Most foreign-owned LLC owners do not need a tax attorney for routine compliance.
Typical cost range: $300-700/hour.
What to Look For in a Cross-Border Tax Professional
Not all CPAs or EAs are qualified to handle foreign-owned LLC tax matters. Here are the specific qualifications and experience markers to look for:
Must-Have Experience
Form 5472 preparation. Ask directly: "How many Form 5472 returns have you prepared in the last 12 months?" If the answer is fewer than 10, this is not their specialty. A professional who regularly handles foreign-owned LLCs should be filing dozens of these annually.
Foreign-owned disregarded entity rules. The professional must understand that a single-member LLC owned by a foreign person is a disregarded entity for tax purposes but still has filing obligations (pro forma 1120 + 5472). If they express confusion about why an LLC needs to file a corporate return, move on.
ITIN application experience. If you need an ITIN, the professional should have direct experience submitting W-7 applications. Ideally, they are also a Certifying Acceptance Agent (CAA), which means they can certify your passport documents without you mailing originals to the IRS.
International tax treaty knowledge. If your home country has a tax treaty with the US, the professional should understand how treaty provisions affect your filing position. Not all treaties are relevant to LLC owners, but a qualified professional should be able to tell you whether your treaty matters.
Nice-to-Have Experience
Multi-state sales tax. If your LLC has sales tax nexus in multiple states, a professional with sales tax experience can handle registrations, filings, and nexus analysis. This is a specialized area — not all international tax CPAs also handle sales tax.
E-commerce business structures. If you sell through Amazon FBA, Shopify, or other platforms, experience with e-commerce tax issues (marketplace facilitator compliance, inventory nexus, dropshipping tax rules) is valuable.
FBAR and FATCA reporting. If you have US financial accounts that trigger foreign reporting obligations in your home country, or if you have foreign accounts that trigger US reporting (FinCEN 114/FBAR), the professional should understand these cross-border reporting requirements.
15 Questions to Ask in Your First Consultation
Use these questions to evaluate whether a tax professional is the right fit:
Experience questions:
1. How many Form 5472 returns do you prepare annually?
2. What percentage of your clients are non-US persons with US LLCs?
3. Are you a Certifying Acceptance Agent (CAA) for ITIN applications?
4. Have you handled IRS penalty abatement requests for late Form 5472 filings?
5. Do you have experience with the Streamlined Filing Compliance Procedures?
Process questions:
6. What documents will you need from me to prepare my Form 5472?
7. How do you handle the pro forma 1120 — do you e-file or paper-file?
8. What is your timeline from receiving my documents to completing the filing?
9. How do you communicate during the engagement — email, phone, portal?
10. Do you provide a copy of the filed return for my records?
Pricing questions:
11. What is your fee for annual Form 5472 + pro forma 1120 preparation?
12. Is the fee fixed or hourly? What is included versus billed additionally?
13. What is the cost for ITIN application preparation if I need one?
14. Do you charge for initial consultations?
15. What are typical additional costs I should budget for (state filings, FBAR, etc.)?
A qualified professional will answer these questions confidently and specifically. Vague answers or inability to discuss Form 5472 specifics are disqualifying.

Red Flags: When to Walk Away
These signs indicate the professional is not the right fit for your cross-border tax needs:
They guarantee specific outcomes. No ethical tax professional guarantees that a penalty will be abated, an audit will have a specific result, or a particular position will be accepted. They can assess likelihood, but guarantees are a red flag.
They do not ask about your business structure. A qualified professional needs to understand your LLC's ownership structure, activities, transaction types, and state registrations before quoting a fee or recommending a course of action. If they quote a flat fee without asking any questions, they are not customizing their service to your situation.
They charge before understanding your scope. While consultation fees are normal, a professional who demands full payment before reviewing your documents or understanding your situation may not be acting in your best interest.
They are unfamiliar with Form 5472. If you have to explain what Form 5472 is, or they need to "look it up," they do not have the experience you need. This is a fundamental form for foreign-owned LLC compliance.
They recommend aggressive positions without discussing risk. If a professional tells you not to worry about filing because "the IRS will never know" or suggests claiming deductions or positions without explaining the risk and legal basis, find someone else.
They cannot explain the pro forma 1120 requirement. The fact that a disregarded entity must file a corporate tax return (pro forma 1120) solely to attach Form 5472 is a basic concept in foreign-owned LLC tax. If they do not understand this, they have not worked with these entities before.
They have no online presence or reviews. While not every great professional has a marketing budget, the complete absence of any verifiable credentials, reviews, or professional directory listings should give you pause.
Where to Find Qualified Professionals
IRS Directory of Enrolled Agents
The IRS maintains a searchable directory of credentialed tax professionals at irs.treasury.gov. You can search by location, credentials (CPA, EA, attorney), and PTIN status. This confirms the professional holds valid federal credentials.
AICPA and State CPA Societies
The American Institute of CPAs (AICPA) and state CPA societies maintain member directories. Look for CPAs with international tax specializations or who list foreign-owned entity compliance as a service area.
CAA Directory
The IRS maintains a list of Certifying Acceptance Agents. If you need ITIN assistance, finding a CAA who is also a CPA or EA is the most efficient arrangement — they can handle both your tax filing and ITIN application.
LLC Formation Service Referrals
Companies that provide LLC formation services (registered agents, formation platforms) often maintain referral networks of tax professionals who specialize in serving their clients' needs. These referrals can be a starting point, but always verify credentials independently.
Online Platforms
Platforms that connect clients with tax professionals (such as TaxFyle, 1-800Accountant, or specialist marketplaces) can help you find professionals with specific international tax experience. Verify credentials and read reviews before engaging.
Professional Referrals
If you know other non-US LLC owners, ask who they use. A referral from someone with a similar tax situation is often the most reliable way to find a qualified professional.
How to Structure the Engagement
Once you select a professional, establish clear terms:
Scope of work. Define exactly what is included: Form 5472 preparation, pro forma 1120, ITIN application (if needed), state filings. Get it in writing.
Fee structure. Fixed fee is preferable for routine annual filings. Hourly may be appropriate for advisory work or complex situations. Confirm what triggers additional charges.
Communication expectations. Agree on response time, preferred communication method, and how you will provide documents (email, secure portal, etc.).
Deadlines. Confirm when you need to provide documents to meet the April 15 deadline (or October 15 with extension). A good professional will tell you their document intake deadline — typically 4-6 weeks before the filing deadline.
Records retention. Confirm the professional will provide you with copies of all filed returns and supporting documentation for your records.
The Cost of Not Having a Professional
The annual cost of a qualified cross-border CPA ($300-800 for Form 5472) is modest compared to the risks of DIY filing or not filing at all:
Late filing penalty: $25,000 per form per year
Incorrect filing: IRS notice, potential penalty, amendment costs
Missed ITIN renewal: additional processing delays, filing complications
Audit without professional representation: significantly worse outcomes
Your tax professional is not just a filing service. They are your first line of defense against IRS compliance issues and your advisor on how to structure your business tax position correctly from the start.
