Why Extreme Filer

Formation done by a specialist, not a call center

Big filing websites hand you a form and leave the hard parts to you. We stay with your company long after the certificate arrives.

Real Specialist Expertise

Your case is led by a US/UK compliance specialist with 8 years in accounting and company formation work — not passed between sales agents.

Every State, Both Countries

LLCs and C-Corps in all 50 US states, plus UK limited companies — so the structure fits your business, not someone's limited catalog.

Fast, Direct Communication

Message us on WhatsApp and get a reply in hours, not days — from one point of contact who already knows your company's details.

Compliance Handled Year-Round

Annual reports, BOI updates and tax filings are tracked on our calendar, so a missed deadline never turns into a penalty or a dissolved company.

About Extreme Filer

Run by a formation specialist who has done this thousands of times — by hand

Extreme Filer is led by Ahmed Ali, a US/UK formation and tax compliance specialist. Before founding Extreme Filer, he headed a company formation department that processed 40–50 EIN and 10–15 ITIN applications every month for non-US founders — real filings, real IRS correspondence, real deadlines.

That experience is now focused on the people big filing websites underserve: non-resident founders, Amazon and Shopify sellers, SaaS builders and freelancers who need a US or UK company to sell and get paid globally — and a specialist who answers on WhatsApp when something comes up.

  • 8 years in accounting, formation and compliance work
  • US LLCs & C-Corps in all 50 states, UK LTDs
  • Built for non-residents: no SSN, no travel, no US address needed
FAQ

Questions non-resident founders ask us first

Can I form a US LLC without living in the US?
Yes. US law does not require LLC owners to live in the United States, hold a visa or have a US address. Non-residents can own 100% of a US LLC — you need a registered agent address in the formation state, which we arrange for you.
Do I need an SSN to get an EIN?
No. An SSN is only needed for the IRS's online application. For foreign owners, we prepare and file Form SS-4 through the IRS channels set up for applicants without an SSN, and your official EIN confirmation letter is delivered to you digitally.
What is an ITIN, and can I get one without visiting an embassy?
An ITIN (Individual Taxpayer Identification Number) is an IRS-issued tax ID for people who aren't eligible for an SSN — it's used for tax filing and for verifying accounts with services like Stripe and PayPal. With our paperless process, you don't visit an embassy and you don't mail your original passport; your documents are verified without the originals leaving your hands.
Which state should I choose — Wyoming, Delaware, or my customers' state?
It depends on what you sell, where your customers are, and which ongoing fees you're comfortable with. Wyoming is popular for low annual costs and privacy, Delaware suits startups planning to raise investment, and some sellers are better off forming where they have real activity. Tell us your situation on WhatsApp and we'll recommend the right state — free, before you pay anything.
What do I have to do every year after formation?
Most states require an annual report and some charge franchise tax. On top of that: BOI information must be kept current with FinCEN, and foreign-owned single-member LLCs must file Form 5472 with a pro-forma Form 1120 with the IRS every year — even with zero income. We handle all of it for you under our compliance packages.
How long does the whole process take?
Company formation typically takes a few business days, depending on the state. EIN timelines for foreign owners vary more, because those applications are processed manually by the IRS. Before you pay, we give you a clear, honest estimate for your specific case — and keep you updated while it's in progress.
