These two forms go together. Here's how to prepare and file them as a package.

Information Return of a 25% Foreign-Owned U.S. Corporation

Fill Now

For foreign-owned single-member LLCs, Form 1120 and Form 5472 are a package deal. You can't file one without the other. Here's the complete walkthrough.

The relationship

Form 1120 is the "cover" return — it reports your LLC's income, deductions, and tax. Form 5472 is the "attachment" — it reports transactions between the LLC and its foreign owner.

For many foreign-owned LLCs with minimal activity, Form 1120 will show mostly zeros while Form 5472 will have the real information.

Preparation order

Step 1: Gather your records

  • Bank statements for the entire tax year
  • Log of all transactions between you and the LLC
  • Any invoices or receipts for business expenses
  • Year-end balance sheet information

Step 2: Fill Form 1120

  • Page 1: Income, deductions, tax computation
  • Schedule L: Balance sheet (beginning and end of year)
  • Schedule M-1: Book-to-tax reconciliation
  • Schedule M-2: Analysis of unappropriated retained earnings

Step 3: Fill Form 5472

  • Part I: Your LLC's information
  • Part II: Your personal information as the foreign owner
  • Part IV: All monetary transactions between you and the LLC

Step 4: Attach and file

  • Form 5472 is attached to Form 1120
  • File by April 15 (or October 15 with extension)

Zero-income example

Your LLC was formed in June, got an EIN, opened a bank account, and you contributed $5,000 as initial capital. No revenue, no expenses.

Form 1120:

  • All income lines: $0
  • All deduction lines: $0
  • Tax due: $0
  • Schedule L: Assets = $5,000 (cash), Equity = $5,000

Form 5472:

  • Part IV, Capital contributions: $5,000
  • All other transaction lines: $0

Active business example

Your LLC earned $80,000 in revenue, had $45,000 in expenses, and you contributed $10,000 in capital plus received $20,000 in distributions.

Form 1120:

  • Gross receipts: $80,000
  • Total deductions: $45,000
  • Taxable income: $35,000
  • Tax (21%): $7,350

Form 5472:

  • Capital contributions: $10,000
  • Distributions / other amounts paid: $20,000

Filing method

  • E-file through your CPA's tax software (preferred)
  • Paper file by mailing to the IRS service center for your state
