Starting a Company in the United States: The Practical Guide

11 min readLast updated 2026-05-06United States

Starting a company in the United States is not one single process under one single system. In practice, company formation is largely state-based, while some tax, identity, and compliance elements also sit at the federal level.

That means founders need to decide not only what type of company to form, but also where to form it, where the business will operate, whether they need an EIN, which licenses or permits may apply, and how ongoing compliance will work.

The foundational rule for the U.S.

The U.S. is not one uniform incorporation regime.

A founder usually needs to think in layers:

  • business model and target market
  • state of formation
  • legal form or entity type
  • federal tax identity and tax awareness
  • state and local licenses, permits, and registrations
  • ongoing compliance

The right sequence in the U.S.

1. Validate the idea and business model first

Just like everywhere else, it is usually a mistake to rush into formation before validating demand.

2. Decide whether the U.S. is only a market or also the formation base

Some founders sell into the U.S. without forming there immediately. Others need a U.S. entity early.

3. Choose the state logic

You need to ask:

  • where founders live
  • where the business will actually operate
  • where employees or contractors are based
  • where customers are concentrated
  • whether there is a real reason to form in a state different from the operating state

4. Choose the entity type

Typical early choices include sole proprietorship, LLC, and corporation.

5. Handle business identity and registrations

Depending on the structure, this may include state formation documents, EIN, state tax registrations, licenses and permits.

6. Build the operating setup

This includes business banking, bookkeeping, contracts, privacy and data handling, insurance, and recurring compliance.

Why state choice matters so much

In the U.S., founders are often exposed to simplified internet folklore such as "just incorporate in Delaware." That can be right in some cases and wrong in many others.

The stronger questions are:

  • where will the company actually do business
  • what kind of company is this
  • are investors realistically part of the path
  • will foreign qualification or additional registrations be required if the company is formed in another state

This is why state selection should be treated as a first-order founder decision, not a footnote.

The most important early U.S. entity types

Sole proprietorship

Often the simplest path for a single person operating a small business. But it provides less structural separation and can be too weak for more ambitious or risk-sensitive setups.

LLC

Often attractive for founders who want a structured company vehicle with flexibility and a more practical operating setup.

Corporation

More relevant when growth, ownership structure, governance, financing, or a venture path become more central.

EIN and why it matters

In the U.S., EIN becomes relevant much earlier than many non-U.S. founders expect. It functions as a business tax identity number and is often needed for banking, tax, payroll, and company administration.

Licenses and permits

One of the most underestimated founder issues in the U.S. is the license and permit layer.

Depending on the business model, the company may need state-level licenses, county or city business permits, professional or regulated activity approvals, or home-based business permissions in some cases.

What international founders often miss

  • the U.S. is not one flat system
  • state choice changes the practical setup
  • EIN and tax identity matter early
  • permits and local requirements can exist even for small businesses
  • operational readiness is not complete just because the entity exists

What U.S. founders often miss

  • forming in a state without understanding where the company will actually operate
  • copying internet advice without understanding the business type
  • ignoring bookkeeping, tax, insurance, and compliance until too late
  • assuming entity formation alone makes the business operationally ready
