How to set up US accounting when you're launching from abroad

You incorporated a Delaware C-corp. Your parent company is overseas. Your accountants are European. And you're about to open for business in the US for the first time.

Getting the books right from the start is not a minor administrative task. US tax and compliance obligations begin the moment you incorporate, not the moment you earn revenue. An electric bike brand expanding from Europe to the US learned this firsthand: their parent company had accountants, their home market had processes, and none of it transferred cleanly to a US subsidiary structure.

This post covers what non-US founders need to get right in the first 90 days, and where the gaps most often appear.

This scenario is drawn from real conversations with Pilot customers.

What does compliance mean for a new US subsidiary?

Compliance for a US subsidiary starts earlier than most international founders expect. A Delaware C-corp has federal and state filing obligations from its date of incorporation, regardless of whether it has a single dollar of revenue. That includes an annual franchise tax to the state of Delaware (due March 1 of the following year), a federal tax return, and, depending on where you operate, state income and sales tax registration in additional states.

For a company whose founders are based abroad and whose parent company operates under European accounting standards, none of this is intuitive. The US tax code has its own rules about entity structure, related-party transactions, and income recognition that do not map neatly to IFRS or the frameworks used by European accountants. A European bookkeeper who handles your parent company's EMEA books is not equipped to handle US federal and state filings without additional expertise.

The risk of getting this wrong is not hypothetical. The IRS assesses penalties for late or incorrect filings, and certain compliance failures, such as missing a Section 5472 information return for a foreign-owned US corporation, carry a minimum penalty of $25,000 per form per year.

One customer who launched a US subsidiary from Europe put it plainly: "We're non-American and this is the first time we have our own business here. We want to make sure we do things by the rules. We don't want to miss anything."

Should you use cash or accrual accounting from day one?

Accrual accounting. Full stop.

Cash-basis accounting records transactions when money enters or leaves your bank account. Accrual accounting records revenue when it is earned and expenses when they are incurred, regardless of when cash moves. For a company with a European parent that needs consolidated monthly financials, cash-basis records are not usable. The parent company needs to know when revenue was earned and liabilities were incurred, not just when wire transfers cleared.

Beyond consolidation, accrual-basis books are what investors expect. If your US subsidiary ever seeks outside funding or prepares for a due diligence process, accrual records are the baseline assumption. Rebuilding books from cash to accrual mid-year or after the fact is a significant accounting project, and one that creates delays at exactly the wrong moment.

The IRS also requires accrual-basis reporting for certain entity types once revenue crosses defined thresholds. Starting on accrual avoids any forced conversion later.

What does your chart of accounts need to handle that standard templates miss?

A chart of accounts is the structured list of categories your business uses to record every financial transaction: assets, liabilities, equity, revenue, and expenses. Most accounting software includes a default template, and for a standalone US business, that template is often adequate.

For a foreign-owned US subsidiary, it is not.

Your chart of accounts needs to include accounts for intercompany transactions, specifically the loans, cost-sharing arrangements, or management fees that flow between your US entity and your parent company. These transactions need to be tracked separately and reported correctly for both consolidation and tax purposes. Transfer pricing rules, which govern how related entities price transactions with each other, apply even to early-stage companies, and the IRS scrutinizes them closely for foreign-owned US businesses.

It also needs to align, at a category level, with your parent company's chart of accounts. If your US subsidiary uses account categories that don't correspond to your parent's structure, consolidation becomes a manual reconciliation project every month. The electric bike brand in this scenario faced exactly that decision: use a standard US chart of accounts, or align with the parent company's European structure. The right answer was to build a chart that served both, with US compliance requirements met and parent-company consolidation enabled.

What happens when you try to handle this with a spreadsheet or a generalist bookkeeper?

Two common workarounds tend to fail here.

The first is tracking inventory and intercompany transactions in spreadsheets. For a pre-revenue company with low transaction volume, this feels manageable. It stops being manageable the moment you have Shopify sales flowing in, Stripe processing payments, Brex recording expenses, and Gusto running payroll. Each system produces its own data in its own format, and reconciling them manually introduces errors. Those errors compound. By the time you're preparing your first year-end return, the reconstruction work can cost more than a year of proper bookkeeping would have.

The second is hiring a freelance CPA or using a generalist bookkeeper who handles general small-business accounting but lacks specific experience with foreign-owned US entities. General bookkeeping handles income and expenses. It does not necessarily address intercompany transaction reporting, Section 5472 requirements, or the specific tax positions available to a pre-revenue C-corp. The gap is not about competence; it's about specialization.

What does the right setup look like for a foreign-owned US startup?

The right setup connects your accounting system to every tool that generates financial data, establishes accrual-basis books from the first month of operations, and includes someone who can tell you what you don't know to ask. As one founder in this situation told us: "We're looking for partners who are proactive, because we're not going to rely on ourselves to see things around corners on the accounting front in the US."

For the electric bike brand, that meant integrating QuickBooks with Brex, Gusto, Stripe, and Shopify from the start, so every transaction flowed automatically into the books without manual entry. It meant setting up a chart of accounts that could support both US compliance and parent-company consolidation. And it meant having a bookkeeper, controller, and tax CPA available as a team, not a solo generalist, so that questions about intercompany transactions or estimated tax obligations had someone with the right expertise to answer them.

Pilot's bookkeeping service is built for exactly this structure: accrual-basis books, integration with the tools you already use, and a team that covers bookkeeping, tax, and controller-level oversight. For a foreign-owned US subsidiary, that combination matters from month one.

The first step is not finding software. It is deciding on your accounting basis, building your chart of accounts, and connecting your systems before transactions accumulate. Every month of backlog is a month of reconstruction work later.

KEY TAKEAWAY

For a foreign-owned US subsidiary, compliance obligations begin at incorporation, not at first revenue. Starting on accrual-basis books, with a chart of accounts that supports both US tax reporting and parent-company consolidation, avoids the reconstruction costs and missed filings that catch most international founders off guard.
