Forming a business takes an afternoon. Forming it well (with the right entity, the right state, the right tax election, and the registrations done in the right order) saves years of avoidable tax and paperwork. Most restructuring we do for clients traces back to a formation decision made quickly at the start.
Choosing an entity
- Sole proprietorship: no filing required and no liability protection. Simple, but rarely the right choice once you have clients, contracts, or employees.
- LLC: a state-law entity that separates business liability from personal assets. For tax, a single-member LLC is ignored by default and a multi-member LLC is taxed as a partnership.
- S-Corporation: not an entity but a tax election, available to LLCs and corporations, that lets owner-employees split income between salary and distributions.
- C-Corporation: taxed at a flat 21% federal rate, with a second layer of tax on dividends. Usually chosen by companies raising venture capital or reinvesting most profit.
For most service businesses the answer is an LLC, with an S-Corp election once profit is high enough for payroll-tax savings to outweigh the extra cost. The LLC versus S-Corp guide shows where that break-even typically falls.
Which state to form in
Forming in Delaware or Wyoming is popular advice, but if you operate in your home state you will usually have to register there as a foreign entity anyway: paying two sets of fees, two annual reports, and keeping a registered agent in both. For most small businesses that operate locally or remotely from one place, forming in your home state is simpler and cheaper. Delaware makes sense mainly for companies planning to raise institutional investment.
The formation checklist
- 1Confirm the name is available with the state and check for trademark conflicts.
- 2File articles of organization or incorporation and appoint a registered agent.
- 3Obtain an EIN from the IRS. It is free directly from the IRS website: paid third-party sites charge for the same form.
- 4Sign an operating agreement or bylaws that cover ownership, decision-making, profit distribution, and what happens if an owner leaves.
- 5Open a business bank account and keep business money in it: commingling is the fastest way to weaken the liability protection the LLC provides.
- 6Register for state taxes you will owe: sales tax if you sell taxable goods or services, and withholding and unemployment accounts before you hire.
- 7Obtain city and county business licenses and any industry-specific permits.
The S-Corp election and its deadline
An S-Corp election is made on Form 2553 and is generally due within two months and 15 days of the start of the tax year it should take effect. Miss it and the election usually applies from the following year, though the IRS provides relief for late elections in many cases when there is reasonable cause. Electing too early is also a mistake: before profit is consistent, the payroll and filing costs can exceed the savings. We model the numbers before filing.
After an interim rule in March 2025, FinCEN exempted U.S.-formed companies from beneficial ownership information reporting under the Corporate Transparency Act. Rules in this area have shifted more than once, so we confirm the current requirement at formation.
Staying in good standing
Formation is not a one-time event. Most states require an annual or biennial report and fee, some charge a franchise or minimum tax regardless of profit, and registered agent details must stay current. Missing these can lead to administrative dissolution, at which point the liability protection you formed the entity for may not hold. We add every state deadline to your compliance calendar at formation.
Formation mistakes that cost money later
- Forming out of state to save on fees, then paying for two registrations, two registered agents, and two annual reports.
- Electing S-Corp status before profit justifies the payroll and filing costs.
- Skipping the operating agreement, leaving ownership splits and exit terms undefined between partners.
- Mixing personal and business spending in the first year, which weakens liability protection and makes tax preparation slower.
- Not registering for sales tax or payroll accounts before the first taxable sale or first hire.
Adding partners or changing ownership
Bringing in a partner changes more than the operating agreement. A single-member LLC becomes a partnership for tax purposes and starts filing Form 1065 with K-1s, capital contributions and ownership percentages need to be documented, and S-Corp ownership is restricted to eligible shareholders with a single class of stock. Planning these changes before signing anything avoids accidental terminations of elections and messy capital accounts later.
Licenses and permits
Beyond state registration, many businesses need a city or county business license, and regulated industries need more: contractor licenses, professional licenses, health permits for food service, alcohol licenses, and occupancy permits for physical locations. Requirements differ by city as much as by state, and several renew annually. We list what applies to your business and location at formation so nothing lapses quietly in year two.
After formation
The first year sets the pattern. Clean books from day one through monthly bookkeeping, owner payroll set up correctly if you elect S-Corp through payroll, and a first-year plan through tax planning avoid the cleanup most new owners face at tax time. If you have a physical location, the local business accounting guide covers the licenses, permits, and property filings that come with it, and when to hire an accountant explains why formation is the moment to start.
