LLC for consultants and agencies

Consulting and agency work means contracts, deliverables and advice that clients rely on. An LLC puts a company between those obligations and your personal assets, satisfies enterprise procurement (EIN, W-9, certificate of good standing, insurance in the company's name) and gives you a clean structure for adding partners or senior staff with equity.

Incofile forms the LLC, obtains the EIN, provides the registered agent and a US business address, drafts the operating agreement for single or multiple owners, and files the S-Corp election when it pays off.

Why agencies formalize early

The first enterprise client usually forces it: their vendor onboarding needs a legal entity, insurance certificates and sometimes a certificate of good standing. Doing it then, under time pressure, is worse than doing it in a quiet week. An LLC also makes it possible to bring in a partner with a defined share and exit terms instead of a handshake.

Owners, partners and the operating agreement

For a multi-owner agency the operating agreement is the most important document you will sign: ownership percentages, capital contributions, profit splits, who can sign contracts, what happens when someone leaves, and how disputes are resolved. Incofile's agreement covers these; have a lawyer tailor it if the stakes are high.

Tax planning for service businesses

A single-member LLC is taxed as a sole proprietorship and a multi-member LLC as a partnership by default. Once profits are well above the owners' reasonable salaries, the S-Corp election can reduce self-employment tax; Incofile files Form 2553. Non-US agency owners cannot use the S-Corp election but typically owe no US income tax on work performed abroad — Form 5472 still applies.

Professional liability insurance

An LLC limits claims to company assets; it does not make claims disappear. Errors-and-omissions insurance in the LLC's name is standard for agencies and consultants and is frequently required by enterprise contracts.

What Incofile does for you

  1. Form the LLC in your chosen state

    We prepare and file the formation documents, act as organiser and provide the registered agent in that state — your home address stays off the public record.

  2. Obtain the EIN

    We apply to the IRS for your Employer Identification Number so you can open the bank account and set up payments.

  3. US business address and mail scanning

    A real US street address for banks, marketplaces and payment platforms, with every letter scanned to your portal ($155/year).

  4. Operating agreement and banking resolution

    The documents banks, Amazon, Walmart and payment processors ask for, prepared in your company's name.

  5. Compliance calendar in your client portal

    Annual report deadlines, registered agent renewal and tax-filing dates, with reminders before each one — plus 24/7 access to every document.

Consultants & Agencies — frequently asked questions

LLC or corporation for a consultancy?

An LLC for almost all consultancies and agencies; a C-Corporation only if you will raise venture capital or grant stock options widely.

Can a non-US agency bill US clients through a US LLC?

Yes — that is one of the most common uses. Work performed outside the US is generally not US-taxed; the annual Form 5472 is required.

How do I add a partner later?

Amend the operating agreement and, in some states, file an amendment. Incofile handles both.

What is a certificate of good standing and why do clients ask?

It is the state's confirmation that the company exists and is current on filings. Procurement teams request it; Incofile can obtain it within days.

What does the LLC cost annually?

The state annual report or franchise tax, registered agent renewal and tax-return costs — no recurring Incofile fees unless you add services.
