Built around founders who live outside the US
We form and maintain US companies for people who run them from somewhere else. Formation, EIN, registered agent, federal filing and bookkeeping, handled by one small team.

US paperwork assumes you live in the US
Every form wants a US address. Every bank wants a Social Security number. Every deadline sits in a US time zone. Nonresident Tax started as the practice its founder wished had existed while dealing with exactly that, and it still only serves founders outside the US.

How we work with you
The same four habits whether you are forming a new company or catching up on filings that fell behind.
Scope first
Before you pay
No price before we understand your situation: entity type, state, activity and who owns what.
Transparent pricing
Always
Every service fee is published. State fees are additional and shown before payment.
Document everything
Every filing
Every filing we prepare is archived in your dashboard with copies and a submission record.
Async by default
Every day
Email and dashboard messaging first, because you may be twelve hours ahead of us. A call is available whenever you would rather talk it through.

Four services, one responsibility each
Each service has a clear boundary so you always know what we did and what stays with you.
- Company formationLLC registration, EIN application, Operating Agreement, registered agent and a business address. State registration and EIN issuance are separate stages. Banking is a separate application with the provider you choose.
- Federal tax filingForm 5472 and pro-forma Form 1120 prepared from your records and submitted, with copies and a submission record. Priced per filing. Processing happens at the IRS on its own schedule.
- BookkeepingMonthly reconciliation and financial statements in a Xero account that belongs to you.
- DissolutionState dissolution and the final federal return, with a checklist of what stays yours to close.
Written down, in your dashboard, in your language
The habits that keep a remote relationship clear.
What you can expect
- Prices published before you sign up, with state fees shown before payment
- Copies and a submission record for every filing we prepare
- Email and dashboard messaging first, with a call when you want one
- Support in English, Spanish, Portuguese or French
What we are not
- Not a law firm, and we do not give legal advice
- Not a bank; providers decide their own approvals
- Not a substitute for tax advice in your country of residence
- Not a guarantee of any tax outcome
What we hold to
Four commitments that decide how a filing, an email and a price are handled.
One area, known deeply
US federal filing and Wyoming or Delaware state work for foreign-owned companies is the whole practice, and the rules are followed as they change.
Prices before you sign up
Every service fee is published. Anything extra is quoted before you agree to it, never discovered on an invoice.
Written down, in your dashboard
Every document, filing and submission record lives in your dashboard, so nothing depends on anyone remembering it.
Your company's good standing first
We measure ourselves by companies kept in good standing, not by how many extra services we can attach.
Who you are working with
