Green Card Tax Transition Guide for Foreign LLC Owners
Getting a green card fundamentally changes your tax obligations. Here's what every foreign LLC owner needs to know about the transition from nonresident to US tax resident.
Tax Disclaimer
Consult a CPA for your specific tax transition. The green card tax transition involves complex reporting requirements that vary based on your individual circumstances, income sources, and timing. This guide provides general information only.
The Big Picture
Before your green card, you are a nonresident alien -- only US-source income is taxed, and you file Form 5472. After your green card, you are a US person -- your worldwide income is taxed, and you file Form 1040. This is one of the most significant tax transitions a foreign LLC owner can face.

What Changes in Detail
Worldwide Income Taxation
As a nonresident, only your US-source income was subject to US tax. After getting your green card, all income you earn anywhere in the world is subject to US taxation. This includes income from businesses, investments, rental properties, and bank accounts in your home country. You may be able to claim a Foreign Tax Credit for taxes paid to other countries, but the filing requirements are significantly more complex.
LLC Becomes a Domestic Disregarded Entity
Your single-member LLC changes classification from a foreign-owned disregarded entity to a domestic disregarded entity. This means LLC income and expenses are reported on Schedule C of your personal Form 1040, rather than on Form 5472 with a pro forma 1120. The LLC itself still does not pay taxes -- it passes through to you -- but the reporting mechanism is entirely different.
Self-Employment Tax
As a nonresident, self-employment tax (Social Security and Medicare) generally did not apply to your LLC income. After your green card, if your LLC earns more than $400 in net profit, you owe self-employment tax at 15.3% (12.4% Social Security + 2.9% Medicare) on net earnings.
Example: If your LLC earns $100,000 in net profit, self-employment tax alone would be approximately $14,130 -- in addition to regular income tax. This is often the biggest surprise for new green card holders.
Quarterly Estimated Payments
As a US tax resident with self-employment income, you must make quarterly estimated tax payments to the IRS (and possibly your state). These are due on April 15, June 15, September 15, and January 15 of the following year. Failing to make estimated payments can result in underpayment penalties.
FBAR and FATCA
As a US person, you may be required to report your foreign financial accounts:
FBAR (FinCEN Form 114)
Required if the aggregate value of your foreign financial accounts exceeds $10,000 at any time during the year. Filed electronically with FinCEN, not the IRS. Due April 15 with automatic extension to October 15.
FATCA (Form 8938)
Required if your specified foreign financial assets exceed $50,000 on the last day of the year or $75,000 at any point during the year (higher thresholds for joint filers and those living abroad). Filed with your Form 1040.
Key Transition Steps
- 1
File Final Form 5472 for the Partial Year
For the year you receive your green card, you may need to file a final Form 5472 covering the portion of the year before you became a US person. This is your last Form 5472 filing for this LLC.
File your final Form 5472 - 2
Start Filing Form 1040
Beginning with your green card year, you file Form 1040 as a US resident. Your LLC income goes on Schedule C (Profit or Loss From Business). If this is mid-year, your first 1040 may cover a partial year as a resident.
- 3
Report Worldwide Income
All income from all sources worldwide must be reported on your Form 1040. This includes foreign business income, rental income, interest, dividends, and capital gains from your home country.
- 4
Set Up Quarterly Estimated Tax Payments
Calculate your expected tax liability (income tax + self-employment tax) and begin making quarterly payments using Form 1040-ES. The IRS expects you to pay as you earn throughout the year.
- 5
File FBAR and FATCA if Required
Determine if your foreign financial accounts trigger FBAR ($10,000 threshold) or FATCA ($50,000 threshold) reporting. Set up a system to track your foreign account balances throughout the year.
- 6
Update LLC Registration if Needed
Depending on your state, you may need to update your LLC's registered agent, business address, or member information to reflect your new US address and status.
Common Mistakes to Avoid
Not Filing the Transition Year Correctly
The year you receive your green card requires careful handling. You may need to file both a final Form 5472 (for the nonresident portion) and a Form 1040 (for the resident portion, or dual-status return). Many people miss one or the other.
Missing FBAR Requirements
FBAR penalties are severe -- up to $10,000 per account per year for non-willful violations, and up to the greater of $100,000 or 50% of account balances for willful violations. Many new green card holders are unaware of this requirement for their home country bank accounts.
Not Realizing Self-Employment Tax Applies
The 15.3% self-employment tax is often the biggest surprise. Unlike income tax (which may be partially offset by foreign tax credits), self-employment tax is owed regardless of taxes paid to other countries.
Forgetting Quarterly Estimated Payments
If you don't make estimated payments and owe more than $1,000 at tax time, you'll face underpayment penalties. Start making quarterly payments as soon as you receive your green card.
Not Reporting Foreign Income
Some new green card holders continue to think only US income is taxable. All worldwide income must be reported -- including income from businesses, properties, and investments in your home country.
Continuing to File Form 5472
Once you're a US person, your single-member LLC is no longer a foreign-owned entity. Continuing to file Form 5472 instead of transitioning to Form 1040 with Schedule C is incorrect and can trigger IRS scrutiny.
File Your Final Form 5472 Before the Transition
If you are about to receive your green card or recently received it, make sure your final Form 5472 is filed for the nonresident portion of the year. Missing this filing carries a $25,000 penalty.
