Form 5472 filing for 2026: what foreign-owned single-member LLCs owe
Form 5472 + pro forma Form 1120 deadline for tax year 2025 is April 15, 2026. Penalty for failure to file is $25,000.
Who owes the filing
Single-member US LLCs owned by non-US persons that are treated as disregarded entities for federal tax purposes. This is the default classification under Treas. Reg. § 301.7701-2 unless C-Corp election was made via Form 8832.
Multi-member LLCs file Form 1065 partnership return instead and are not subject to Form 5472 in this manner.
What's reported
Reportable transactions between the LLC and the 25%+ foreign owner during the tax year: capital contributions, distributions, loans, sales, services, and other transactions. The form must be filed even when there are no reportable transactions, as long as the LLC exists.
Form 5472 is attached to a pro forma Form 1120 (mostly blank). The two together constitute the complete filing.
Cost of CPA help
$200-$500 typical for an uncomplicated single-member LLC filing. Complex situations (multiple owners, foreign parent structures, large capital flows) cost $1,000-$3,000.
Anchorage successor providers maintain partner network of CPAs at standard pricing without referral fees. Customer pays the CPA directly.
