The one-person software company stopped being unusual. A single founder outside the United States can now build a product, write the marketing, run support and ship updates — and the hardest remaining problem is not building it. It is getting paid for it.
That is the gap a US LLC for SaaS founders fills. This guide covers when it makes sense, which state to pick, how the tax picture really works for software revenue, and the compliance you take on.

Why software founders form US companies
Payment infrastructure
Stripe is the default billing layer for SaaS, and it is straightforward for a US company. From many countries it is unavailable, restricted, or comes with terms that make subscription billing painful. A US LLC plus an EIN gives you standard Stripe access, which means subscriptions, trials, proration, dunning and invoicing all just work.
Credibility with business buyers
Selling to companies means going through procurement. A US entity with a real invoice, a proper MSA and a US bank account clears checks that an individual with a foreign account does not.
App stores and marketplaces
Apple, Google, AWS Marketplace, Shopify and similar platforms are all simpler to onboard with a US entity and an EIN.
A company you can actually sell
SaaS businesses get acquired. Buyers purchase entities with clean books and clear IP ownership — not a personal PayPal account and a folder of invoices. Building inside a company from the start makes an exit possible later.
IP ownership that survives scrutiny
If you contract designers or developers, having the company own the work through proper assignment is what a future buyer or investor will check first.
LLC or C-Corp?
This is the decision that actually matters, and it comes down to one question: are you raising money from US investors?
| LLC | C-Corp (Delaware) | |
|---|---|---|
| Bootstrapped / indie SaaS | Right choice | Overkill |
| Raising from US VCs | Investors will push back | Expected |
| Annual cost | Low | $300+ franchise tax, plus accounting |
| Tax treatment | Pass-through | Taxed at entity level |
| Admin burden | Minimal | Board minutes, cap table, filings |
| Stock options for staff | Awkward | Straightforward |
For the overwhelming majority of independent software founders, the LLC is correct. Take the C-Corp when a term sheet actually requires it — you can convert then. Our LLC vs C-Corp comparison goes deeper.
Which state?
New Mexico for most: $50 to file, no annual report, nothing to pay the state after year one. Wyoming if you are accumulating meaningful cash or IP inside the company and want the stronger asset-protection statute for $60 a year.
Delaware only earns its $300 annual franchise tax when US institutional investors are involved. It buys you nothing with Stripe, AWS or your customers. Full breakdown in our state comparison.
Tax for software revenue
Here is where founders get nervous, usually unnecessarily.
If you are a non-US resident, writing the code from your own country, with no US office, no US employees and no US-based servers you own, your income is generally not effectively connected to a US trade or business. US federal income tax on it is typically zero.
Selling to American customers does not by itself create a US tax obligation. Where the work is performed matters far more than where the customers are.
Two things to be careful about:
- Filing is still mandatory. Form 5472 plus a pro forma 1120 every April, $25,000 penalty if missed, zero income no excuse.
- US sales tax on SaaS is genuinely messy. Some states treat software subscriptions as taxable, others do not, and thresholds vary. If you sell direct through Stripe rather than through a merchant of record, this is worth a conversation with a specialist once revenue is meaningful. Our sales tax nexus guide explains the framework.
And your home country still taxes you under its own rules — the US entity changes nothing there.
The setup that works
- Form the LLC — New Mexico or Wyoming.
- Get the EIN — no SSN required, two to four weeks.
- Open the bank account — Mercury, Relay or Wise. Use a real business address, not your registered agent’s, or you risk rejection.
- Set up Stripe with matching company details, then add Stripe Billing or a merchant of record like Paddle or Lemon Squeezy if you would rather they handle global sales tax.
- Get an Operating Agreement — banks ask for it, and it documents that you own the company and its IP.
- Calendar Form 5472 for every April.
Stripe direct or merchant of record?
A decision specific to software businesses:
- Stripe direct — lowest fees, full control of the checkout and customer relationship, but global sales tax and VAT become your problem.
- Merchant of record (Paddle, Lemon Squeezy, FastSpring) — they sell to the customer as the seller of record and handle VAT and sales tax worldwide, in exchange for a higher percentage.
Many non-resident founders start with a merchant of record to avoid the tax complexity, then move to Stripe direct once revenue makes the fee difference material. Both work with a US LLC.
Frequently asked questions
Do I need a US LLC to sell software internationally?
Not legally, but it is usually the shortest path to reliable Stripe access, business customers and USD banking.
Will forming a US LLC make me pay US tax?
Generally no, if you have no US presence and perform the work abroad. The annual Form 5472 filing is still required regardless.
Should I form in Delaware to look investor-ready?
Only when investors actually require it. Until then it is $300 a year for appearances.
Can I convert my LLC to a C-Corp later?
Yes. Conversion is routine and normally done at the point of a funding round, with proper legal advice.
Does a US LLC help with app store payouts?
Yes — Apple and Google onboarding is simpler with a US entity, EIN and US bank account.
What about AI products specifically?
The structure is identical. Whether you sell an AI tool, a plugin or a classic SaaS, the entity, banking and tax logic are the same.
