Launching a company is a major milestone—but for many US small business owners, the real work starts right after incorporation. Following a clear post-incorporation checklist helps you stay compliant, avoid costly mistakes, and build a stable foundation for your business.
Whether you’re a solo founder or a startup team, this guide walks you through everything you need to do after incorporation, with tips on how accounting services in US can help simplify the process.
Before anything else, make sure your ownership structure is clearly defined and documented. This ensures legal clarity and sets the foundation for future fundraising or business transitions.
Issue founder shares and agreements
Formalize who owns what by issuing shares (for corporations) or membership interests (for LLCs). Make sure to sign share purchase agreements and keep clear records.
File IRS 83(b) election (if applicable)
If your shares are subject to vesting, file Form 83(b) with the IRS within 30 days to potentially lower future taxes.
Once incorporated, you need to complete key registrations to operate legally and meet government requirements.
Apply for an EIN
An Employer Identification Number (EIN) from the IRS is essential for taxes, banking, and hiring. It’s free and easy to apply online.
Register with state and local agencies
Depending on your location, this may include registering your business entity, filing beneficial ownership information, and applying for business licenses or permits.
Getting your financial systems in place early helps you stay organized, maintain legal protections, and make smarter business decisions.
Open a business bank account
Keep business and personal finances separate for liability protection and easier bookkeeping.
Implement accounting and payroll systems
Start tracking income, expenses, and payroll from day one. Whether you use software or outsource to accounting services, it’s critical for compliance and clarity.
Consider a business credit card
Optional, but useful for building credit and managing day-to-day business spending.
Maintaining proper documentation protects your business and shows you’re running it professionally—something investors, partners, and regulators expect.
Draft bylaws or operating agreements
These outline your business structure and internal rules—bylaws for corporations, operating agreements for LLCs.
Keep records of key decisions
Document board or member meetings, ownership changes, and other major actions in official minutes or resolutions.
Your business may require specific licenses or permits depending on the industry, location, and type of operations.
Research and apply for required licenses
This can include federal permits, state registrations, and local business licenses. Make sure you’re cleared to operate legally in all jurisdictions where you do business.

Compliance doesn’t stop after incorporation. Regular filings and governance tasks help you stay in good standing and avoid penalties.
File annual and periodic reports
Most states require annual reports, franchise tax filings, or other updates. Mark deadlines on your calendar and don’t miss them.
Maintain corporate governance
Depending on your structure, hold required meetings and document decisions. This shows you’re following the rules of your chosen entity type.
If you’ve developed a product, brand, logo, or invention, now’s the time to protect it from misuse or duplication.
Register your intellectual property
Consider applying for trademarks, copyrights, or patents to legally safeguard your brand and innovations.
Once the groundwork is done, you’re ready to hire, market, and grow. Just make sure you’re set up to handle day-to-day operations and compliance.
Hire employees (if applicable)
Register for state payroll taxes, report new hires, and stay up to date on labor law requirements.
Get ready for tax season
Understand your tax deadlines and payment requirements. Setting aside funds and working with accounting services can make filing smooth and stress-free.
