Many foreign founders think bookkeeping is unnecessary if their U.S. LLC has no clients, no revenue, or no activity. But the IRS doesn’t see it that way. Even a single transaction—like an owner contribution, paying a filing fee, or reimbursing an expense—counts as activity that must be tracked. Clean bookkeeping is not just about knowing your numbers; it’s about keeping your company compliant and avoiding expensive mistakes.
This guide explains what bookkeeping looks like for a foreign-owned U.S. LLC, why it matters, and how Bookmate helps you keep everything in order.
Why bookkeeping matters, even with no income
The IRS requires all foreign-owned LLCs to file certain forms each year. The details on those forms—like contributions, payments, and reimbursements—come directly from your bookkeeping records. For example, a foreign-owned single-member LLC must file Form 5472 with a pro forma 1120. That filing reports transactions such as owner contributions, loans, or payments to the owner.
Multi-member LLCs must file Form 1065, with K-1s to members and often K-2s and K-3s if members are foreign. The allocations of profit or loss shown on those forms depend on accurate bookkeeping. Without proper records, it’s easy to misreport or miss something, and the penalty for a late or missing Form 5472 starts at $25,000 per year.
What counts as activity?
Many founders assume that no revenue means no activity. But for IRS purposes, activity includes even the smallest financial movements. Putting money into your LLC bank account, paying the Wyoming or Delaware annual fee, reimbursing yourself for expenses, or sending and receiving payments to foreign owners are all activities that must be tracked.
Even if your LLC hasn’t signed a client or made a sale, those actions create reportable transactions.
How to handle bookkeeping as a foreign founder
Bookkeeping doesn’t have to be complicated, but it does need to be consistent. The first step is separating business and personal funds. All company money should flow through your LLC’s bank account, not your personal one. Every transaction should then be recorded, even if it’s just a single deposit or expense.
Keeping supporting documents such as invoices, receipts, and wire confirmations will make your records much stronger. Some founders prefer to keep things simple with a spreadsheet, while others use tools like QuickBooks or Xero for added convenience. The choice is less important than making sure everything is captured clearly and accurately throughout the year.
Example: A year with “no income”
Consider a founder in Brazil who forms a Wyoming single-member LLC in April. She wires $3,000 to the company account to cover future expenses. She pays the Wyoming $60 annual fee and reimburses herself $200 for software she bought for the business. Even though the LLC had no revenue, it still had three reportable transactions.
Those activities must be included in her bookkeeping and then reported on Form 5472 with a pro forma 1120. Without clean records, it would be easy to miss one of these items and risk a penalty.
Why bookkeeping helps beyond taxes
Accurate books don’t just help at tax time. They make it easier to open and maintain bank accounts by showing clean financial records. They also help if you apply for payment processors like Stripe or PayPal, which often ask for financial documentation.
Investors or partners will take you more seriously if you can provide transparent numbers, and when filing season comes, you’ll save yourself the stress of trying to reconstruct the year’s transactions at the last minute.
