APROBLEM 01
LLC or C-Corp — which fits?
The right choice depends on your business model, investment path, and tax posture, not just on the fact that you incorporated.

From US Incorporation
to Payments, Tax, Operations — In One Team.
Forming a US company is just the first step. EIN, tax structure, Stripe payments, websites, customer inquiry flow, and operations automation all have to connect before real sales begin.

WHAT FOUNDERS HIT
You know you should incorporate in the US. Where to actually start is the hard part.
Most people start by thinking US incorporation is simple. Then entity type, tax, EIN, bank, Stripe, website, customer payments, and ongoing operations all entangle at the same time.
BPROBLEM 02
EIN, taxes, filing schedules are unfamiliar
EIN is the IRS taxpayer ID, but the application path, timing, and supporting documents differ across founders.
“IRS forms in English + US address requirement”
CPROBLEM 03
Stripe and international payments
Having an entity does not mean payments work. The Stripe account, website, product copy, policy pages, and inquiry flow all have to land together.
“Stripe rejection cases are common”
DPROBLEM 04
Post-formation operations are unclear
State taxes, annual reports, registered agent, tax management, and accounting records all keep going.
“Missing Annual Report can dissolve your entity”
EPROBLEM 05
English documents and global communication
Formation, tax, payments, platform support, customer copy — all of it eventually shows up in English.
“Platform English responses are stressful”
FPROBLEM 06
Plenty of agencies form companies. Few stay for operations.
Forming an entity and running a business are different things. The structure has to support customer payments, inquiries, and operator management.
“The "form-and-leave" pattern is widespread”
That is why US incorporation is not paperwork. It is the first operational system you set up for the global business.
WHY iGEM IS DIFFERENT
We do not stop at forming the entity.
For the business to actually run after incorporation, tax, payments, web, documents, and operations have to align. iGEM STUDIO sees the whole flow and brings the right specialists in for each area.
01
We start from the business structure
What you are selling, who the customer is, how payments come in, and how tax and operations will run later — all before paperwork.
02
Tax perspective is built in
Post-formation tax management matters. Lucas reviews entity structure and tax risk and connects you with specialist partners for ongoing management when needed.
03
Payments and web carry through
After formation we design the page customers actually pay on, the Stripe connection, and the inquiry / booking flow.
04
Operations automation extends it
Customer inquiries, bookings, document handling, post-payment communication, internal management — automated so a small team can run a global business.
The entity is the start. The real goal is a structure where overseas customers can pay and the operator can run the business steadily.
FOUR-EXPERT TEAM
Not one person — four specialists work on your US incorporation together.
US incorporation is not finished with paperwork. Tax, payments, web, operations, and global communication all carry on. iGEM STUDIO moves as one team across those areas.

FAQ
Common questions
Can you do US incorporation only, on its own?+
Yes. iGEM STUDIO's strength is connecting incorporation to payments, web, tax, and operations afterward. We separate the conversation between formation-only and the full sales structure.
LLC or C-Corp?+
Depends on the purpose. Funding, shareholder structure, tax treatment, operating style, and expansion plans all shift the answer. Even Delaware recommends consulting a lawyer or accountant when choosing.
Is EIN required?+
For most US entity operations, EIN matters. EIN is the 9-digit IRS taxpayer ID used for tax filings and reporting. The application path varies by founder residence, Responsible Party, and US address — worth checking before you start.
Can I apply for EIN directly — why use a service?+
Yes, EIN can be handled directly. iGEM STUDIO is not selling a number issuance. The value is connecting the whole structure — tax, payments, web, and operations — after the entity is in place.
Does a Delaware entity need a Registered Agent?+
Yes. Delaware requires every entity to have a Registered Agent with a physical Delaware address. So registered-agent setup needs to be planned during formation.
Are there annual responsibilities?+
Yes. Delaware corporations generally have an Annual Report and Franchise Tax; LLCs have Annual Tax. Corporations file by March 1; LLCs / LPs / GPs pay by June 1. Annual schedules carry on after formation.
What about BOI filing?+
BOI rules have shifted recently — verify timing. FinCEN currently states (per the March 26, 2025 interim final rule) that US companies and US persons no longer need to file BOI. Still varies by entity type and foreign-company status; re-confirm at the time of work.
Can you connect Stripe?+
Yes. Stripe account approval depends on business model, documents, country, and risk review. iGEM STUDIO organizes payment prep documents, the website, product description, customer guidance, and operating flow to improve approval odds and operational reliability.
Do you provide legal counsel?+
iGEM STUDIO is the execution partner across formation, tax, payments, web, and operations. When legal judgment is needed, we connect you with attorneys or specialist partners — that is the safe path.
Do not stop at forming the entity. Start so you can actually sell and operate.
US incorporation is the start. Connecting tax, payments, web, customer inquiry, and operations automation makes the whole launch much steadier.
Tell us your current business state and we will lay out the order — from incorporation through payments and operations.
