What are business incorporation services, and what do they include?

To incorporate is to register your business as its own legal entity with a US state. That entity, not you personally, signs contracts, holds a bank account, and owes tax. It is the step that separates your money from the company’s money.

Business incorporation services handle that registration for you. A good provider helps you pick the right entity, files the formation documents with the state, appoints a Registered Agent, and gets your EIN. You end up with a company that is ready to bank and trade, not just a name on a certificate.

The main choice is entity type. An LLC (Limited Liability Company) is simple and flexible, with profits taxed on your own return. A C corporation is a separate taxpayer that US investors expect. An S corporation is a tax election that can lower self-employment tax once profits are high enough. We explain each option in plain terms and match it to how you actually plan to earn and grow.

What the best business incorporation services cover

The best providers do more than file a form. They explain the trade-offs in plain language, include the Registered Agent and EIN, and stay reachable after formation, when the real questions start.

Our expertise covers

What is included when you incorporate with Zmartly?

  • 01

    Business Details

    Pick your company name, entity type (LLC, C corporation, or S corporation), and state. Our qualified accountants help you choose based on your goals and tax position, so you get it right the first time.

  • 02

    Submission and Payment

    You share the details and pay the flat $399. We prepare and file every document with the state and appoint your Registered Agent, so nothing is missed. State filing fees are separate and vary.

  • 03

    Post-Formation

    You receive your Articles of Organization or Incorporation, EIN (Employer Identification Number), and a customized Operating Agreement. We walk you through what each document means, so you know exactly what you hold.

  • 04

    Registered Agent

    A dedicated representative who receives official state documents and legal notices for your company. Most states require one, and the first year is included.

  • 05

    US Mailing Address

    A US business mailing address to receive and forward your company mail securely, so you do not need a US address of your own.

Which entity is right for you: LLC, C corporation, or S corporation?

This is where good business incorporation services earn their fee. The entity decision is the most expensive one to unwind later, so we settle it before we file, not after. The right answer depends on how you plan to make money and whether you will raise investment.

An LLC suits most freelancers, ecommerce sellers, and small operating businesses. It has flow-through tax and little admin. A C corporation is the right home if you plan to raise from US investors or issue stock options. An S corporation is a tax status that can pay off once profit is high enough to justify a salary plus distributions.

The best incorporation services for small business

For a small business, the best incorporation services keep it simple: usually an LLC, a clear Operating Agreement, and an EIN, without pushing you into a structure you do not need yet.

Which state should you form your company in?

You can form your company in any state, not only the one you live or trade in. Delaware is what venture investors expect for a C corporation, thanks to its settled corporate law. Wyoming suits a single-owner LLC that wants privacy and low ongoing fees. If you are unsure, we look at where your customers, staff, and tax exposure actually sit, then recommend the state that fits.

For most businesses that actually operate in one place, your home state is the sensible answer. Forming out of state means you still register as a foreign entity where you trade, which adds a second fee for no real benefit. State filing fees and franchise taxes vary widely and change often, so we confirm the current cost with you before filing.

Our Delaware business incorporation services cover the full setup: formation, Registered Agent, and the EIN, plus the annual report and franchise tax reminders that keep a Delaware entity in good standing.

Business incorporation services in California

California charges its own annual franchise tax on most entities, and the amount and timing change, so we flag it upfront before you commit to forming there.

Business incorporation services in Florida

Florida is a popular home state for founders who trade there, with a straightforward annual report. We confirm the current filing fee and due date with you.

Why it pays off

Why founders choose Zmartly to form a US company

  • Compliance Reminders

    Automated alerts and expert support so you meet annual report and franchise tax deadlines and keep your company in good standing.

  • Certificate of Incorporation

    An official document that confirms your business is legally registered in the US.

  • EIN Registration

    Your EIN (Employer Identification Number), issued by the IRS (Internal Revenue Service), is needed to open a bank account, hire staff, and file taxes.

  • Post-Incorporation Package

    Includes core documents like your Operating Agreement or Corporate Bylaws, plus organizational resolutions and onboarding guidance.

  • Filing in All 50 States

    Expedited processing in every state with electronic submissions and priority handling, so most certificates come back in days.

  • EIN Support Without an SSN

    We file Form SS-4 with the IRS for founders who have no US Social Security Number, so the EIN step does not stall you.

Who uses online business incorporation services?

Founders often search for a business incorporation service near me, but formation is a filing you complete online, from anywhere. Online business incorporation services suit anyone who needs a US entity without a US trip: early startups raising money, ecommerce and Amazon sellers who need a US bank account, and consultants signing US clients.

They also suit non-resident and international founders. You do not need to be a US citizen or resident to own a US company. If you have no US Social Security Number, you can still get an EIN, and an ITIN (Individual Taxpayer Identification Number) where a personal filing needs one. We form US companies for founders from Toronto and Vancouver to Singapore and Hong Kong. You keep full ownership and control, and you can run the whole company online, from wherever you already live and work.

Top services for global business incorporation

The top services for global business incorporation are built for founders who are not in the US. That means EIN filing without an SSN, a US mailing address, and a clear path to remote banking, all handled for you.

Business incorporation services for founders in Canada

Canadian founders often form a US LLC or C corporation to sell into the US market. We handle the US side, so you can keep your Canadian company and add a clean US entity alongside it.

How does the incorporation process work, step by step?

The process is short, and our business incorporation services handle the whole US side for you. Most of your time is spent on step one.

  1. Tell us the basics. Choose your company name, entity type, and state. If you are not sure, our qualified accountants help you decide before anything is filed.
  2. We file and pay. For a flat $399, we prepare and submit your formation documents to the state and appoint your Registered Agent. State filing fees are separate. You do not need a US address, a US visit, or a US Social Security Number.
  3. You receive your company. For most states you get your Articles and Certificate within days, along with your EIN and a customized Operating Agreement or Corporate Bylaws. You are ready to open a bank account and trade.

What happens after your company is formed?

Good business incorporation services should not end at filing, because the questions that follow are the ones that catch founders out. Three things matter most right after formation.

First, your EIN. This is your company’s federal tax ID, and you need it to open a bank account and file taxes. We obtain it for you on Form SS-4, which takes longer for non-residents without an SSN. Second, your Registered Agent stays in place to receive state and legal mail. Third, most new companies must file a BOI (Beneficial Ownership Information) report with FinCEN (Financial Crimes Enforcement Network) under the Corporate Transparency Act, and the deadline depends on your formation date.

After that, you have annual reports and, in many states, a franchise tax to keep the company in good standing. None of it is hard once it is set up, but each item has its own deadline, and a single missed filing can push your company out of good standing. We send reminders and can handle the filings, so nothing lapses while you focus on the business.

Formation is the easy part. The best services for online business incorporation track your EIN, BOI report, and annual deadlines for you, so a missed filing never puts your company at risk.

Common questions

Frequently asked questions.

An LLC (Limited Liability Company) suits most freelancers, side hustles, and small operating businesses, with flow-through taxation and minimal formality. An S corporation works once net profit is high enough to justify a reasonable salary plus distributions, which can lower self-employment tax. A C corporation is the right answer if you plan to raise from US venture capital, issue stock options, or operate cross-border. We assess the right structure as part of formation, not after.

Delaware suits C corporations raising venture capital, thanks to its predictable corporate law and the Court of Chancery, which is what investors expect. Wyoming suits single-member LLCs that prioritize privacy and low fees. Your home state is best for most operating businesses where you actually have employees, customers, or premises, because registering out of state adds a foreign qualification fee for no real benefit. State filing fees and franchise taxes vary and change often.

The $399 covers preparing and filing your formation documents, your Certificate of Incorporation, EIN (Employer Identification Number) registration with the IRS, a customized Operating Agreement (LLC) or Corporate Bylaws (corporation), organizational resolutions, a Registered Agent for the first year, and a US mailing address. The state's own filing fee is separate and varies. Expedited filing in all 50 states is included as standard, so most certificates come back within days, not weeks.

Yes. The US has no residency or citizenship requirement for owners or directors of LLCs and C corporations. You will need an EIN (Employer Identification Number), which we obtain for you on Form SS-4, and a US Registered Agent and mailing address, both included. Non-residents without a US Social Security Number wait longer for the EIN. Once it is issued, you can open a US bank account remotely through providers such as Mercury, Relay, or Wise Business.

You have an annual report and, in many states, a franchise tax in your state of formation (amounts vary by state and change often). You also have a federal tax return (Form 1120, 1120-S, or 1065 depending on entity type), state tax returns where applicable, and a BOI (Beneficial Ownership Information) report filed with FinCEN under the Corporate Transparency Act for most small entities. We send reminders and handle the filings as part of our ongoing US compliance package.

Yes. Once your EIN is issued you can open a US business account remotely through providers such as Mercury, Relay, or Wise Business, with no US trip and no Social Security Number required. We time the bank application to follow your EIN so there is no waiting around, and we tell you exactly which documents each provider asks for.

Formation itself is quick. With expedited filing included as standard, most state certificates come back within a few days rather than weeks. Your EIN is the variable: if you hold a US Social Security Number it is issued in days, and if you do not, we obtain it for you via Form SS-4, which currently takes around 4 to 6 weeks for non-residents. We keep you updated at each stage so you always know where your company stands.
