How to Accept International Payments Legally

Here's something worth knowing upfront: U.S. entities — including sole proprietors, LLCs, and S-Corps — are generally permitted to accept payments in foreign currencies and from foreign clients without special licenses. There's no requirement to get government approval to do business internationally. You don't need to register with any federal agency just because a client in France pays you.

What you do need to get right is:

1. How you report that income (it all goes on your tax return) 2. How you handle foreign currency conversion and associated costs 3. Whether your payment processor is compliant with U.S. anti-money-laundering (AML) and Know Your Customer (KYC) regulations 4. Whether foreign financial accounts associated with your business trigger FBAR obligations Beyond those four areas, accepting international payments is largely a business decision rather than a legal minefield.

Not all payment processors are built for international work. Here's a breakdown of the most popular options for U.S.-based solopreneurs and small business owners:

Stripe. Stripe is the gold standard for U.S. entrepreneurs doing international business. It supports over 135 currencies across dozens of countries, offers clean invoicing and subscription billing, integrates with essentially everything, and has robust fraud protection. Standard transaction fees are 2.9% + $0.30 per transaction, with an additional 1.5% for international cards and 1% for currency conversion. For nomads or entrepreneurs who also operate internationally, Stripe Atlas allows you to incorporate a U.S. company and immediately access Stripe payments — even if you're not currently based in the U.S.

Wise Business (formerly TransferWise). Wise isn't a payment processor in the traditional sense — it's a multi-currency account that functions similarly to a bank. Where it excels is holding and converting currency at the mid-market exchange rate (the real rate, without a hidden markup). If you invoice a client in euros and want to hold those euros before converting, Wise is hard to beat. You can get local account details in USD, EUR, GBP, AUD, and more, making it easy for foreign clients to pay you "like a local." Wise is registered as a Money Services Business (MSB) in the U.S., which means it's regulated by FinCEN. That's important — it means the platform is compliant with U.S. financial regulations.

PayPal. PayPal is ubiquitous and trusted globally, which makes it useful for reaching clients in markets where it's a familiar payment method. It's available in over 200 countries and supports 25 currencies. The tradeoff is cost: PayPal charges a cross-border fee of 1.5% plus a currency conversion fee of 2.5%, which adds up quickly on large invoices. For occasional international payments, it's fine. For high-volume international billing, the fees become a meaningful line item.

SWIFT wire transfers. For large B2B payments — particularly for consulting or agency work — a straightforward SWIFT bank wire is often the cleanest solution. Your client sends funds directly to your U.S. business bank account. No intermediary processor, no percentage-based fee, just a flat wire fee (typically $20–$45 on the receiving end). The downsides: it's slow (2–5 business days), involves manual coordination, and isn't ideal for small or recurring payments.

Merchant of Record services (Paddle, Lemon Squeezy). If you sell digital products internationally — software, courses, templates, ebooks — consider a Merchant of Record (MoR) service. These platforms legally become the seller of record for your transactions, meaning they handle sales tax, VAT, and GST compliance across dozens of jurisdictions automatically. For solo digital product sellers, this eliminates an enormous compliance burden and is worth the slightly higher processing fees (typically 5–10%).

Every time you accept a foreign currency payment and convert it to USD, there's an exchange rate involved — and most platforms make money on the spread between the real rate and the rate they offer you. Over the course of a year, this can represent hundreds or thousands of dollars in unnecessary costs.

Strategies to minimize this:

Invoice in USD whenever possible. If your clients can pay in dollars, the conversion happens on their end, not yours. Hold foreign currency using Wise or Mercury, and convert when rates are favorable. Compare conversion rates before initiating large transfers. The difference between Wise's mid-market rate and a traditional bank's rate is often 2–4%.

Every dollar you receive from international clients is taxable U.S. income and must be reported on your federal return. This is true regardless of whether the client is in a treaty country, regardless of whether you received a 1099, and regardless of whether the payment came in a foreign currency.

If you received foreign currency, you must convert it to USD at the exchange rate on the date of receipt (or the average annual rate if you use the simplified method). The IRS accepts both approaches, but consistency matters — pick one and stick to it.

If you accept payment into a foreign bank account or a foreign PayPal account (PayPal accounts held outside the U.S. are treated as foreign financial accounts), you may have an FBAR obligation if aggregate foreign balances exceeded $10,000 at any point during the year.

Payment processors in the U.S. are required by federal law to implement AML and KYC programs. When you sign up for Stripe, Wise, PayPal, or any regulated financial platform, they will verify your identity, your business, and potentially your clients. This is normal and legally required — it's not unique to international transactions.

What this means practically: maintain clean documentation of your client relationships, contracts, and the legitimate business purpose of large incoming payments. For most solopreneurs, this is just good business hygiene. If you're moving large sums regularly from certain jurisdictions, some processors may request additional documentation. Have it ready.

The Office of Foreign Assets Control (OFAC) maintains a list of sanctioned countries, entities, and individuals with whom U.S. persons cannot conduct financial transactions. Currently, U.S. businesses are prohibited from accepting payments from clients in countries like Iran, North Korea, Syria, Cuba (with limited exceptions), and Russia (with significant restrictions).

Responsible payment processors block transactions from these jurisdictions automatically. But if you're doing business internationally, especially in less common markets, it's worth knowing OFAC exists and checking the current sanctions list before entering into client agreements.

One practical note: when working with international clients, your contracts should specify:

Which currency governs the agreement Which country's courts have jurisdiction in the event of a dispute Your payment terms, including currency conversion expectations

Late payment remedies U.S. law will generally govern contracts for U.S.-based businesses if the agreement specifies it. Including a governing law clause removes ambiguity and gives you stronger footing if you ever need to pursue a non-paying international client.

Accepting international payments legally is, for most U.S. entrepreneurs, not a legal obstacle — it's a logistics and cost-optimization challenge. The legal framework broadly supports cross- border commerce. What requires intentionality is choosing platforms that serve your business model, managing currency conversion costs intelligently, and keeping your tax and FBAR reporting current.

Start simple: Stripe for card payments, Wise for large currency transfers and holding balances, and a U.S. business bank account (Mercury and Relay are both excellent for entrepreneurs) as your operational hub. You can always add complexity as your international client base grows.
