Running a US company from outside the US comes with real advantages — access to American clients, payment processors, and credibility — and one responsibility that doesn’t wait for you to feel ready: keeping accurate books. This guide walks through what “accounting” actually covers for a non-resident-owned LLC or C-Corp, which compliance forms sit on top of it, and how to decide between doing it yourself and having someone handle it for you.
Why accounting looks different from abroad
A US entity puts you inside a regulatory system built with domestic businesses in mind, and a few things change once you’re running it from another country.
You’re very likely operating in more than one currency — invoicing clients in EUR or GBP while your tax return has to land in USD. Every transaction between you and your own company (funding it, paying yourself, lending it money) counts as a reportable event, not just an internal transfer. And you’re keeping two sets of obligations in view at once: US federal requirements and whatever your home country expects, without a local accountant down the street to lean on — which usually means leaning on cloud tools, digital receipt capture, and remote-friendly service providers instead of walking paperwork into an office.
None of that makes the bookkeeping harder in principle — it just means the systems need to handle currency conversion and related-party tracking from day one, rather than being bolted on later.
It also matters more than it might seem for banking and, eventually, funding. Banks and payment processors expect clean records before they’ll open accounts or keep them open, and if you’re building a Delaware C-Corp toward a future funding round, investors will expect GAAP-style financial statements prepared to a standard your own spreadsheet probably isn’t hitting yet.
The core bookkeeping work
Three activities do most of the heavy lifting, and they build on each other.
Monthly bookkeeping is the daily record: every transaction — income, expenses, transfers, vendor and customer payments — pulled from your connected bank accounts and cards, categorized against IRS-consistent categories, with receipts attached for an audit trail. Skip this and nothing downstream works; you can’t file an accurate return, defend a deduction, or trust your own numbers when you need them for a decision.
Financial statements turn that record into something you can actually use. A profit & loss statement shows what you earned and spent over a period, and which products, services, or markets are actually driving your margin. A balance sheet shows what you own and owe at a single point in time — useful for understanding business value or backing up a loan or investment application. A cash flow statement tracks money actually moving in and out — often the most useful of the three for a small business, since profit on paper and cash in the bank aren’t the same thing, and it’s usually the first thing that tells you a crunch is coming.
Bank reconciliation matches your books against your actual bank statements every month, catching missed transactions, bank fees, and timing differences before they turn into bigger errors — or into questions during a filing. If you’re weighing where to hold funds in the first place, our guide to opening a US bank account as a non-resident covers what banks look for.
None of this requires you to be in the US. Cloud accounting software plus digital receipt capture means the whole process runs the same whether you’re managing it from Lagos, Lisbon, or Lima.
Multi-currency accounting, done right
If you accept payments from customers in more than one currency, that needs to be handled deliberately rather than approximated at tax time. Each transaction gets recorded in its original currency, converted to USD at the exchange rate on that day, and tracked for any resulting foreign-exchange gain or loss — because the IRS wants your final numbers in USD regardless of where the money originated. Done well, this gives you both views at once: your financials in USD for compliance, and a currency-by-currency breakdown for understanding how the business actually performs.
As an example: a SaaS company billing customers in EUR, GBP, and CAD needs each charge recorded in its original currency, converted at that day’s rate, rolled up into a single USD-denominated set of financial statements for the IRS — while still being able to see performance broken out by market. That’s the kind of setup worth building once, properly, rather than approximating every few months.
Who feels this most
The accounting load isn’t identical for every non-resident-owned business — a few profiles run into it hardest:
- E-commerce sellers juggling multiple sales channels, currencies, and sales-tax obligations that shift as revenue grows in different states.
- SaaS and subscription businesses recognizing recurring revenue across currencies and needing metrics an investor would recognize.
- International consultants and agencies invoicing clients directly in their local currency while still reporting cleanly in USD.
- Delaware C-Corps raising capital, where GAAP-consistent statements aren’t a nice-to-have — they’re what due diligence expects to see.
If you recognize your business in any of those, the systems in this guide are worth setting up properly from the start rather than retrofitting them later, once the transaction volume and the currencies involved have already multiplied.
Where accounting meets tax filing
Clean books aren’t just good practice — they’re the input your annual federal tax filing draws from. Your accountant uses the same categorized, reconciled data to prepare Form 1120 (C-Corps), Form 1065 (multi-member LLCs), and the Form 5472 and pro-forma 1120 filing required of foreign-owned single-member LLCs. If more time is needed, Form 7004 gets you an automatic six-month extension on most of these — but the extension applies to filing, not to keeping records current, so the accounting work still has to happen on its usual schedule. If a deadline is coming up and you’re not sure which one applies to you, our 2026 tax deadlines guide breaks it down by entity type.
Compliance requirements you can’t skip
Beyond the standard bookkeeping every US business needs, a few reporting obligations sit on top specifically because your company has a non-US owner. None of them are complicated once you know the shape of them — they mostly trip people up when nobody’s tracking them until a deadline is already close. Here’s what applies and when:
| Requirement | What it covers | Filed with | Deadline |
|---|---|---|---|
| Form 5472 | Transactions between your US entity and its foreign owner(s) | IRS, attached to a pro-forma Form 1120 | April 15, or Oct 15 with an extension |
| FBAR (FinCEN Form 114) | Foreign financial accounts with an aggregate balance over $10,000 at any point in the year | FinCEN, separately from your tax return | April 15, automatic extension to Oct 15 |
| FATCA (Form 8938) | Foreign financial assets above $50,000 (year-end) or $75,000 (any point in the year) | IRS, with your tax return | Same as your tax return |
| BOI reporting | Beneficial ownership information | FinCEN | Largely doesn’t apply to domestic entities anymore — see below |
Form 5472 is the one every foreign-owned single-member LLC files, every year, regardless of income — including capital contributions, distributions, loans in either direction, and payments between you and the company. The standard penalty for missing it starts at $25,000 per form, stated calmly here because it’s avoidable: the fix is simply making sure a return goes in every year the LLC exists. We track qualifying transactions as part of our accounting service specifically so this never becomes a year-end scramble.
A dormant LLC with zero income still owes a Form 5472 if any money — even a single funding deposit — moved between you and the company that year.
FBAR and FATCA both concern foreign accounts, but they’re separate filings to separate agencies with different thresholds — FBAR triggers at $10,000 in aggregate foreign account balances, FATCA at higher thresholds and a broader asset definition. FBAR exists primarily to help FinCEN spot money laundering and unreported foreign income; FATCA layers on a wider disclosure aimed at foreign financial assets generally, not just bank accounts. Many non-resident owners with accounts back home end up filing both, and good bookkeeping is what tells you exactly when you’ve crossed either threshold instead of finding out at filing time.
An update worth knowing: in March 2025, FinCEN exempted virtually all domestic (US-formed) companies from beneficial ownership reporting under the Corporate Transparency Act. If your LLC or corporation was formed in the US, BOI reporting almost certainly doesn’t apply to you anymore — it now mainly concerns foreign entities registered to do business here.
DIY software or a professional service?
Cloud accounting platforms have made self-service bookkeeping genuinely workable for simple businesses. We run client books on Xero, which fits international founders especially well — unlimited users on every plan, strong multi-currency handling, and wide adoption outside the US. Other mainstream platforms cover similar ground with different strengths, and if you’re already on one, clean exports make switching straightforward.
DIY tends to work well when:
- Your transaction volume is low and your structure is simple.
- You’re already comfortable with basic accounting concepts.
- You have the time to keep records current every month, not just at year-end.
- You don’t need investor-grade financial statements.
Professional oversight tends to earn its cost when:
- You’re juggling multiple currencies and want the conversions handled correctly the first time.
- You’d rather someone else track Form 5472 transactions than assemble them under deadline pressure.
- Your time is worth more spent on the business than on categorizing transactions.
- You want statements a bank, investor, or auditor will accept without follow-up questions.
Many founders land on a hybrid approach — software for day-to-day entry, professional oversight for reconciliation and compliance — which is close to how our own service works, just with the software and the oversight bundled together.
Keeping your records clean, year-round
A few habits do most of the work, regardless of who’s handling your books:
- Separate business and personal money completely. A dedicated business account isn’t a formality — mixing funds makes deductions harder to defend and can undermine the liability protection your LLC or corporation exists to provide.
- Capture receipts as you go. A photo at the point of purchase, synced to your accounting system, beats reconstructing three months of spending from memory.
- Categorize consistently, using the same chart of accounts every month so your reports stay comparable over time.
- Log currency details on every foreign transaction — original amount, exchange rate, USD conversion, and date — so nothing needs to be guessed at later.
- Check cash flow weekly. Fifteen minutes reviewing balances and upcoming payments catches problems while they’re still small.
- Close the books monthly: reconcile every account, record anything outstanding, and generate statements you can actually trust.
- Keep records for at least three years after you file (seven is safer for larger items) — the same window the IRS can look back at if questions come up.
Mistakes we see non-resident owners make
- Waiting until tax season to set up accounting. Reconstructing a year of transactions from bank statements after the fact is slower, costlier, and less accurate than recording them as they happen.
- Assuming zero income means no Form 5472. It doesn’t — the filing requirement is tied to the entity’s existence and any reportable transaction, not to revenue.
- Mixing business and personal expenses. This is the fastest way to lose legitimate deductions and complicate an otherwise clean set of books, and in a worst case it can undercut the liability separation your entity is supposed to provide.
- Recording foreign transactions inconsistently. Using different exchange-rate sources or skipping the conversion step altogether leads to numbers that don’t reconcile later.
- Losing track of state obligations. Franchise tax and annual report deadlines vary by state and run on their own calendar, separate from your federal return.
- Under-documenting deductions. A vague expense description or a missing receipt is often enough for a deduction to get disallowed later — a quick note on purpose and vendor at the time takes seconds and saves the reconstruction.
- Not watching for state economic nexus. Selling into states where you cross their sales thresholds can create a state sales-tax or income-tax obligation you didn’t know you had.
- Missing deadlines because no one owned the calendar. Form 5472, FBAR, and your annual return all have dates — building a simple compliance calendar (or having someone build it for you) prevents this outright.
None of these are unusual or embarrassing — they’re the predictable spots where a system built for domestic businesses collides with running one from abroad. Every one of them is fixable, and most are cheaper to fix before they happen than after.
Getting started, or getting current
If you’re deciding what to do next, it usually comes down to a short assessment: are your records accurate and current today, do you understand which of the compliance items above apply to you, and could you produce clean statements if a bank or the IRS asked tomorrow? If any of those gives you pause, the fix is the same whether you handle it yourself or bring in help — set up (or clean up) your systems now, rather than waiting for a deadline to force the issue.
It’s also worth weighing the full cost of the DIY route honestly, not just the sticker price of doing it yourself: the hours it takes from running the business, the risk of a mistake compounding quietly for months before it’s caught, and the opportunity cost of time that could go toward growth instead of categorizing transactions. For a lot of founders, that comparison is what tips the decision toward professional help — not because DIY can’t work, but because the real cost of DIY is rarely just the software subscription.
How we handle accounting for you
Our accounting plan is built around the parts of this guide that are easiest to get wrong from abroad. Every client gets Xero set up and managed on their behalf — no software learning curve — with unlimited transactions in any currency, all accounts connected automatically, and monthly Profit & Loss, Balance Sheet, and Cash Flow statements. We track your reportable Form 5472 transactions throughout the year rather than reconstructing them in April, and the same clean data feeds directly into your federal tax filing when it’s due.
In practice, that looks like:
- We connect your accounts with read-only bank and card access, so transactions sync automatically instead of being entered by hand.
- We categorize everything, applying IRS-consistent categories and flagging anything that needs a quick answer from you.
- We reconcile monthly, matching your books against actual statements and resolving discrepancies before they compound.
- We deliver statements you can use — for your own decisions, for a bank or investor, or as the foundation for your annual filing.
It’s one plan, priced simply: $1,999 a year, covering unlimited transactions, quarterly check-ins with a dedicated specialist, and real people to talk to when a question comes up — no setup fees, and a 30-day money-back guarantee if it’s not the right fit. It pairs naturally with our company formation plans if you’re setting up a new Wyoming or Delaware entity, or slots in on its own if your company already exists.
Frequently asked questions
Do I need accounting if my company has no revenue yet?
Yes. Even a pre-revenue company usually has formation costs and other expenses worth recording properly, and a foreign-owned LLC owes Form 5472 for reportable transactions regardless of income. Setting systems up early is far easier than rebuilding a year of records later.
How does multi-currency accounting actually work?
Each transaction is recorded in its original currency, then converted to USD at that day’s exchange rate for IRS-compliant reporting. You can still view performance broken down by currency — the USD conversion is for compliance, not for how you understand your own business.
What’s the difference between Form 5472 and FBAR?
Form 5472 reports transactions between your US company and its foreign owner. FBAR reports foreign bank accounts once the aggregate balance crosses $10,000. They go to different agencies (IRS versus FinCEN), and many owners need to file both.
Can I just use accounting software myself instead of hiring anyone?
You can, especially with a simple, low-volume business. Most non-resident owners eventually bring in professional oversight once multi-currency transactions, Form 5472 tracking, and state-specific rules start adding up — often through a hybrid approach that keeps the software but adds a specialist behind it.
What if my books are already behind?
We can reconstruct records from bank and card statements — it takes longer than staying current does, but it’s a well-worn process. The sooner you start, the smaller the cleanup.
Do you handle inventory and cost of goods sold?
Yes. For product-based businesses, we track inventory purchases and value, calculate cost of goods sold, and can connect to most e-commerce or point-of-sale platforms so inventory updates flow through automatically.
What about state income tax or franchise tax?
We track those alongside your federal obligations — Delaware franchise tax, Wyoming annual reports, and any state income or sales tax nexus your business creates as it grows — so nothing gets discovered after the fact.
Can I get more time if I’m not ready by the deadline?
Yes — filing Form 7004 gets most entities an automatic six-month extension on their federal return, including the Form 5472 and pro-forma 1120. The extension moves the filing date, not the bookkeeping you still need to have done to file accurately, so it buys time rather than removing the underlying work.
Whichever route you choose, the goal is the same: books you trust, a compliance calendar that isn’t a surprise, and less time spent on any of it than you’re spending today. If you’d rather hand the bookkeeping and compliance tracking to someone else, visit Accounting for plan details, or contact us and we’ll walk through what your specific setup needs.
