About us

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.

Why we exist

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.

  • Founded and run by Serkan Haslak, who also writes the guides on this site

Our process

How we work with you

The same four habits whether you are forming a new company or catching up on filings that fell behind.

  1. Scope first

    Before you pay

    No price before we understand your situation: entity type, state, activity and who owns what.

  2. Transparent pricing

    Always

    Every service fee is published. State fees are additional and shown before payment.

  3. Document everything

    Every filing

    Every filing we prepare is archived in your dashboard with copies and a submission record.

  4. Async by default

    Every day

    Email and dashboard messaging, because you may be twelve hours ahead of us. Every answer stays in writing, so you can come back to it.

What we do

Four services, one responsibility each

Each service has a clear boundary so you always know what we did and what stays with you.

How we work

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, so every answer stays in writing
  • Support in English, Spanish, Portuguese, French or German

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
Our values

What we hold to

Four commitments that decide how a filing, an email and a price are handled.

  1. 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.

  2. Prices before you sign up

    Every service fee is published. Anything extra is quoted before you agree to it, never discovered on an invoice.

  3. Written down, in your dashboard

    Every document, filing and submission record lives in your dashboard, so nothing depends on anyone remembering it.

  4. Your company's good standing first

    We measure ourselves by companies kept in good standing, not by how many extra services we can attach.
