A Related-Party Loan Can Move a Filing Beyond a Simplified Cash-Transfer Workflow

The practical answer

A related-party loan introduces questions that are different from simply adding up owner cash contributions. Identify the loan records, the parties, and the relevant balances before assuming that a simplified cash-transfer preparation method covers everything in the file. For amounts borrowed on line 17, the outstanding-balance method uses beginning and ending balances on 17a and 17b. Under the monthly-average method, skip 17a and enter the monthly average on 17b.^{[1, p.5] [1, p.6] [1, p.3] [2, p.2]}

Scope and the records behind the answer

The discussion follows the entity, form and transaction conditions identified below. The same label on a different form can have a different purpose. Keep the relevant entity and reporting period visible while you compare the requirements, and treat each stated exception as part of the rule rather than an optional footnote.

A side-by-side preparation table

Work through the official requirements

Borrowed balance method

For amounts borrowed on line 17, the outstanding-balance method uses beginning and ending balances on 17a and 17b. Under the monthly-average method, skip 17a and enter the monthly average on 17b.^{[1, p.5]}

Loaned balance method

For amounts loaned on line 31, the outstanding-balance method uses beginning and ending balances. Under the monthly-average method, skip 31a and enter the monthly average on 31b.^{[1, p.5] [1, p.6]}

Records sufficiency

Keep permanent books and records sufficient to establish the correctness of the federal return and the treatment of related-party transactions, together with the detailed requirements of Regulations section 1.6038A-3.^{[1, p.3]}

Field/section 17a: Beginning balance

Under the outstanding-balance method, enter the beginning balance. Under the monthly-average method, leave this a-field blank and use the corresponding b-field.^{[2, p.2] [1, p.5]}

This applies when: Part IV concerns transactions with foreign related parties, not domestic related parties.

Field/section 20: Loan guarantee fees received

If this foreign-related-party transaction occurred, report its U.S.-dollar amount under Loan guarantee fees received. Include accrued receipts or payments where the accrual method applies.^{[2, p.2] [1, p.5]}

This applies when: Part IV concerns transactions with foreign related parties, not domestic related parties.

Field/section 34: Loan guarantee fees paid

If this foreign-related-party transaction occurred, report its U.S.-dollar amount under Loan guarantee fees paid. Include accrued receipts or payments where the accrual method applies.^{[2, p.2] [1, p.5]}

This applies when: Part IV concerns transactions with foreign related parties, not domestic related parties.

Penalty qualifying failures

For an applicable reporting corporation, failure to furnish section 6038A information at the prescribed time and in the prescribed manner, maintain required records, or satisfy the foreign-record requirements can trigger an initial $25,000 penalty per tax year, subject to the related-party rules.^{[3] [4]}

This applies when: An applicable section 6038A filing or recordkeeping obligation and a corresponding failure must exist. The $25,000 amount here applies to tax years beginning on or after January 1, 2018.

Keep this limit in view: Reasonable cause requires a separate review; do not describe the penalty as automatically and unconditionally applying to every LLC. The amount differs for tax years beginning before January 1, 2018.

Field/section Top annotation: Foreign-owned U.S. DE

Write "Foreign-owned U.S. DE" across the top of the pro forma Form 1120 to identify this special filing.^{[1, p.2]}

Field/section Name: Name

Enter the foreign-owned U.S. DE's name.^{[5, p.1] [1, p.2]}

An illustrative preparation scenario

In this hypothetical preparation example, a company's transaction file contains owner funding plus an agreement that describes a loan. The preparer separates those records, identifies the borrowing or lending direction, and checks the balance method in the relevant fields before deciding whether the work needs a broader review. The preparer checks three points: Is the entity borrowing or lending? Which agreement and balance records support the entry? Does the transaction exceed the proposed preparation scope? The file remains a working comparison until the relevant facts and applicable instructions have been checked together. No agency outcome is assumed.^{[1, p.5] [1, p.6] [1, p.3] [2, p.2]}

This is a planning illustration, not a statement that a particular filing has been accepted or that an entity qualifies for a tax result. Use the source-backed distinctions above to decide what information still needs to be established before a form is completed.

A review sequence you can actually use

1. Is the entity borrowing or lending?
2. Which agreement and balance records support the entry?
3. Does the transaction exceed the proposed preparation scope?

Write down the answer and the record that supports it, rather than marking a question complete because a field contains text. When two records disagree, identify whether the difference concerns the entity, an individual, the reporting period or the type of change. That makes the remaining question specific enough to resolve against the relevant instruction.

Keep the scope of a preparation service separate from the government requirement. A service intake question may gather information for a workflow; it does not create an exception, extend a deadline or determine whether a transaction is reportable. The cited government material remains the basis for those conclusions.

Questions to settle before moving forward

How should I check records sufficiency?

Keep permanent books and records sufficient to establish the correctness of the federal return and the treatment of related-party transactions, together with the detailed requirements of Regulations section 1.6038A-3. ^{[1, p.3]}

How should I check field/section 17a: beginning balance?

Under the outstanding-balance method, enter the beginning balance. Under the monthly-average method, leave this a-field blank and use the corresponding b-field. Part IV concerns transactions with foreign related parties, not domestic related parties.^{[2, p.2] [1, p.5]}

How should I check field/section 20: loan guarantee fees received?

If this foreign-related-party transaction occurred, report its U.S.-dollar amount under Loan guarantee fees received. Include accrued receipts or payments where the accrual method applies. Part IV concerns transactions with foreign related parties, not domestic related parties.^{[2, p.2] [1, p.5]}

How should I check field/section 34: loan guarantee fees paid?

If this foreign-related-party transaction occurred, report its U.S.-dollar amount under Loan guarantee fees paid. Include accrued receipts or payments where the accrual method applies. Part IV concerns transactions with foreign related parties, not domestic related parties.^{[2, p.2] [1, p.5]}
