Serving non-resident founders around the world

A tax and formation team built entirely around non-resident founders

We started Nonresident Tax after living the exact problem we now solve: US compliance built for people who live in the US. Today we handle formation, tax filing, and accounting for founders who don't — and only that, so we can do it well.

Non-residents are the only clients we take — no side focus, no add-on service

Tax compliance team reviewing founder workflows in a warm office

Alongside the banks and tools founders already use

From Wyoming and Delaware, we've supported founders banking and filing from around the world.

Why founders trust us

Credentials you can check

The specifics that actually matter when you're deciding who handles your US compliance.

US-licensed CPAs & EAs

Every return is reviewed by a licensed CPA or Enrolled Agent before it's filed — not just software.

Support in 4 languages

English, Spanish, Portuguese, and French, spoken natively by the team — never routed through a translator.

Form 5472 in every plan

The filing every foreign-owned LLC needs is included automatically in every plan — never an upsell.

Accuracy guarantee

If we get something wrong on a filing we prepared, we fix it and refile it — at no cost to you.

Our story

From frustration to a company built to fix it

Nonresident Tax started with a problem its founder ran into directly: forming and running a US company from outside the country meant chasing paperwork built for people inside it. Every form assumed a US address. Every bank assumed a Social Security number. Every deadline assumed you were in the same time zone as the IRS.

Since 2015, we've built the practice we wished had existed — one that handles the non-resident parts by default. Founders have used it to form Wyoming and Delaware entities, get an EIN without an SSN, and stay compliant year after year — handled by a small team focused on nothing else.

The problem

US compliance is built around people who live in the US — a mailing address, an SSN, a bank branch nearby. None of that applies when you’re running the business from somewhere else.

Our mission

Make US business formation and compliance work by default for founders who don’t live in the US — not as a workaround, as the starting point.

The solution

Specialists who only handle non-resident cases, backed by a compliance dashboard that tracks every deadline automatically.

Where we are now

Businesses formed and maintained for non-resident founders around the world.

Our values

What drives us forward

Everything we do comes down to a few commitments: real expertise, clear pricing, and a genuine stake in your business succeeding.

Expert knowledge

A deep, current understanding of US tax law and international ownership rules, kept up to date as regulations change — this is the only area we work in.

Transparent service

Clear pricing, honest timelines, and no hidden fees. If something costs extra, you hear it from us before you agree to it — not on the invoice.

Technology-first

Automation and a client-facing compliance dashboard handle the repetitive parts, so filings go out faster and more accurately — fully automated deadline tracking, not a spreadsheet.

Your success first

We measure ourselves by the businesses we help launch and keep in good standing — not by how many other services we can sell you along the way.

Values in action

Every filing, every email, and every price we quote is meant to reflect the same three commitments.

Complete transparency
Continuous innovation
Client success first

What makes us different

Specialists, not a general formation service

We form and maintain Wyoming LLCs, Delaware LLCs, Wyoming C-Corps, and Delaware C-Corps — always for founders who live outside the US.

One country, deep expertise

US federal and Wyoming or Delaware state filings — that’s the whole practice. We don’t handle UK, Canadian, Singaporean, or any other jurisdiction’s rules, and that focus is why we’re fast and accurate at the ones we do.

Built for founders without an SSN

An EIN without an SSN, Form 5472, and an ITIN when one’s actually needed — routine work for us, not an exception a generalist has to research.

A team that speaks your language

Clients reach us in the language they think in. Our team includes native speakers of Spanish, Portuguese, French, Turkish, and more.

Deadlines tracked automatically

Every filing deadline — federal, state, annual report — is monitored from the day your entity is formed, so nothing depends on you remembering it.

We run on Xero for accounting, e-file with the IRS (Form 5472 goes out by fax), and accept international payments through Stripe, Wise, and Mercury — all visible in one compliance dashboard. See how we handle your books

Accuracy Guarantee

If we get something wrong on a filing we prepared, we fix it and refile at no cost to you. A real accountant reviews every return before it goes out.

Our process

How we work with you

The same four steps, whether you're forming a new entity or catching up on filings that fell behind.

Scope first

We never quote a price before understanding your situation — entity type, state, activity, and who owns what.

Transparent pricing

Every service fee is posted publicly. State fees pass through at cost, with nothing marked up.

Document everything

Every filing we make is archived in your dashboard with confirmation, so you can find it again later.

Async by default

We work with founders around the world, so email and dashboard messaging come first. A live call is available whenever you’d rather talk it through.
