What To Do After Forming an LLC: Complete First-30-Days Checklist (2026)

Get your EIN (Employer Identification Number)
Apply free at IRS.gov using the EIN Online Assistant. Takes 15 minutes. You receive your EIN instantly upon completion. You need it to open a business bank account, hire employees, and file federal taxes. Full EIN guide here.

Store your formation documents securely
Save your Articles of Organization (the state-approved document), your state's approval notice, and your EIN confirmation (CP 575 or online confirmation page) in a secure, backed-up location. Both digital (cloud storage with backup) and physical (fireproof folder) copies are recommended. You will need these documents frequently: for bank accounts, licenses, contracts, and future compliance filings.

Open a dedicated business bank account
This is the single most important step for maintaining your LLC's liability protection. Commingling personal and business funds is the most common reason courts pierce the corporate veil and hold LLC owners personally liable. Bring to the bank: your EIN confirmation, Articles of Organization, operating agreement (if already signed), and government-issued photo ID. Major banks that work well for LLCs: Chase Business Complete, Bank of America Business Advantage, or local credit unions (often the fastest and easiest for new businesses).

Separate all business expenses from personal immediately
From day one, pay all business expenses from the business account only. Transfer your initial business capital into the business account. If you paid for formation costs personally, reimburse yourself through the business account with documentation. Set up a business credit card using your EIN (not your SSN) to start building business credit separately.

Draft and sign your operating agreement
Required by law in California, New York, Maine, Missouri, and Delaware. Strongly recommended everywhere else. For single-member LLCs: establishes that the LLC is a separate entity from you personally (critical for veil-piercing defense). For multi-member LLCs: defines ownership percentages, profit/loss allocation, member voting rights, and what happens if a member leaves or dies. Never use a formation service's template without reviewing it; many have default provisions that conflict with your state's laws.

File your FinCEN Beneficial Ownership Information (BOI) report
New LLCs formed after January 1, 2024 must file a BOI report with FinCEN within 90 days of formation. LLCs formed after January 1, 2025 have 30 days. The report identifies the beneficial owners (those who own 25% or more, or who exercise substantial control) and company applicants. File free at boiefiling.fincen.gov. Civil penalties for late filing: up to $500/day. As of early 2026, domestic US entities had received temporary exemptions due to court challenges; verify current status at fincen.gov before your deadline.

Hold your organizational meeting and document it
For multi-member LLCs: hold a formal organizational meeting of members, elect any managers, adopt the operating agreement, approve the initial capital contributions, and document everything in written minutes. For single-member LLCs: written consent to action is sufficient in place of a formal meeting. Keep these records in your LLC's permanent records book.

Set up your business records system
Create a physical or digital LLC records book that contains: Articles of Organization, operating agreement, membership certificates (for multi-member LLCs), EIN confirmation, meeting minutes and written consents, annual report filings, and all contracts and agreements. Many formation services sell fancy binders for $50 to $150. A well-organized digital folder costs nothing and is more accessible.

Check your registered agent setup
Confirm your registered agent is in place and has your current contact information. Your registered agent receives legal service of process and compliance notices from the state. Missing a notice because your registered agent has the wrong address can result in default judgments and administrative dissolution of your LLC. If you used a formation service, verify that registered agent service is active and confirm the renewal date so you do not miss it.

Register for state and local taxes
Depending on your state and business type, you may need to register for: state income tax withholding (if you have employees), state sales tax permit (if you sell taxable goods or services), state unemployment insurance (if you have employees), and local business tax registration. Most states have an online business registration portal where you can complete all state tax registrations in one place. Contact your state Department of Revenue for the specific requirements for your LLC type and industry.

Research and obtain required business licenses
Federal licenses are required for specific industries: firearms, alcohol, aviation, broadcasting, trucking (interstate), agriculture, and financial services. State licenses vary widely: contractors, healthcare providers, real estate agents, attorneys, and CPAs need state-issued licenses. Local permits include city business licenses (required in most cities), zoning permits, and health department permits (for food-related businesses). The SBA's Business License and Permits page is a good starting resource for federal requirements.

Set up your accounting system
Establish a bookkeeping system before you have your first transaction, not after. Options range from a simple spreadsheet to software like QuickBooks, Wave (free), or FreshBooks. Regardless of which tool you use, the core requirements are: tracking all income with dates and payer information, tracking all expenses with receipts and business-purpose documentation, maintaining separate records for each LLC if you have multiple entities, and keeping records for at least 3 years (7 years for anything related to employment taxes).

Determine if you need to make estimated tax payments
If your LLC will owe more than $1,000 in federal taxes for the year, you are required to make quarterly estimated tax payments. For most pass-through LLCs, this means estimating your annual profit and paying 25% of the estimated tax each quarter (due April 15, June 15, September 15, and January 15). Underpaying estimated taxes results in a penalty even if you pay the full amount when you file your annual return.

Get business insurance
Your LLC provides liability protection from business debts and lawsuits, but it does not insulate the LLC's assets from judgments. Insurance protects those assets. Most LLCs need at minimum: general liability insurance ($300 to $800/year for basic coverage), professional liability (if you provide professional services), and commercial property (if you have equipment or inventory). Home-based businesses: your homeowner's or renter's insurance does not cover business equipment or business liability. You need a separate endorsement or policy.

Register your business name as a trademark if applicable
Your LLC name registration with the state protects the name within that state only, and only from other registered entities. It does not give you exclusive rights to use the name. For trademark protection (which gives you nationwide exclusive rights to use the name in your industry), file with the USPTO at USPTO.gov. The application fee is $250 to $350 per class of goods/services. If your brand is important to your business, trademark registration is worth the cost.

Set up your business digital presence
Register a domain name that matches or closely relates to your LLC name. Set up a business email address at that domain (Google Workspace $6/user/month or Microsoft 365 $6/user/month). Create a Google Business Profile if you serve local customers. Set up a basic website or landing page. Using a personal Gmail or Yahoo address for business communications signals to potential clients and partners that your business is not fully established.

Create your standard contracts and agreements
Before your first client transaction, have your key contracts in place: a client services agreement or terms of service, a confidentiality/NDA template, and an independent contractor agreement if you plan to work with contractors. Many of these templates are available free from state bar associations or low-cost from legal document platforms. Having contracts reviewed by an attorney is worth the cost for any high-value ongoing relationships.
