Year-End for a Foreign-Owned U.S. Company: Four Things to Settle Before 31 December

A foreign-owned U.S. company has four things to settle before 31 December, and none of them can be settled afterwards. Everything else about the year can be reconstructed in the spring from bank statements. These four are decisions, and a decision not made before the year closes has been made by default.

One: the treaty paperwork on payments leaving the United States

When a U.S. company pays interest, dividends, royalties or certain service fees to a foreign person, the default is that 30 percent is withheld and sent to the government. A treaty can reduce that rate, sometimes to zero, but only where the recipient's documentation is already in the payer's hands when the payment is made.

Two things to check before the last payment run of the year:

• Expiry. A W-8 form generally expires on the last day of the third calendar year after it was signed. Forms signed in 2023 stop being valid on 31 December 2026, and the obligation to withhold at the full rate resumes the next day.
• Accuracy. A form that names the wrong entity, omits a treaty article, or carries a foreign tax number that no longer exists is not a valid form. The payer carries the liability for getting this wrong, which is why payers are strict about it.

The withholding is reported annually, and the statements go to recipients and to the government in March. Correcting an over-withholding after that point is a refund process rather than an adjustment.

Two: the record of what the company and its owner charged each other

Related-party charges are expected to look like charges between unrelated parties. A management fee, a licence fee, a services charge, a loan with or without interest, a payment made by the parent on the U.S. company's behalf: each one needs a rationale, and the rationale is expected to exist in writing by the time the return is filed.

What a workable record looks like, at minimum:

• An agreement that says what is being provided, by whom, and on what basis it is priced.
• Evidence the service was actually provided, at the level of invoices, timesheets or deliverables.
• Some comparison showing the price is in a defensible range.
• Consistency between the two sides of the transaction, in both countries' books.

December is when the year's activity is still recent enough to describe honestly. The version assembled eighteen months later, under a question, is always weaker, and it looks it.

Three: the transactions that go on the annual information return

A U.S. corporation that is at least 25 percent foreign-owned, and a foreign-owned single-member LLC, report their transactions with related parties every year. For the disregarded LLC, the return exists only to carry that report: a bare corporate return with the information form attached.

The items that belong on it are broader than most owners expect:

Commonly reported	Commonly forgotten
Sales and purchases between the company and its owner	Capital contributed to the company during the year
Interest paid or received	Amounts distributed or withdrawn by the owner
Rents and royalties	Expenses paid by the owner on the company's behalf
Management and service fees	Loans made in either direction, including interest-free ones

The penalty for failing to file starts at $25,000 for each year, and repeats while the failure continues after notice. It applies whether or not the company made any money, and it applies to companies that did almost nothing all year. Dormancy is not an exemption; it is just a shorter form.

The practical year-end task is a reconciliation: list every movement of value between the company and anyone related to it, and make sure the bookkeeping agrees with the bank.

Four: the timing decisions that only exist while the year is open

A handful of choices are fixed by the calendar rather than by the filing:

• Distributions. A dividend paid on 30 December belongs to this year's withholding and this year's reporting. The same payment two days later belongs to the next year's.
• Bonuses and accruals. When a charge is incurred, and whether it is paid, decides which year it lands in.
• Entity classification. How an entity is treated for U.S. tax can be elected, and the election has a window: it can generally be made effective up to 75 days before the date it is filed, and up to twelve months after. A January filing can still reach back into the closing weeks of the previous year, which makes this the one item on the list with a short grace period rather than a hard stop.
• Bad debts and write-offs. A receivable that is genuinely uncollectable is dealt with in the year it becomes so, on the evidence that exists then.

The sequence that works

1. November: pull every W-8 on file, check signature dates, request replacements for anything signed in 2023 or earlier.
2. Early December: list every related-party transaction for the year and confirm each has an agreement behind it.
3. Mid December: decide distributions, bonuses and write-offs, and instruct them with enough time to clear before the 31st.
4. Late December: reconcile the owner account so the information return can be prepared from something trustworthy.
5. January: contractor and wage statements. March: withholding returns. April: the corporate return and the information return, or an extension of the filing date.

None of this is complicated. It is simply time-limited, and the limit is a date rather than a deadline anyone will remind you about.

If the company has never filed the information return, that is a different and more urgent conversation, and there are established routes for it. The company intake is where that starts, and the business tax page sets out the wider annual cycle.
