Step-by-Step Guide to US LLC Tax Filing

Step 1: Determine Your LLC Tax Classification

The IRS recognizes LLCs as:

1. Single-member LLCs – treated as sole proprietorships by default
2. Multi-member LLCs – treated as partnerships by default
3. Electing to be taxed as S-Corporation or C-Corporation – optional

Your tax classification affects which forms you file and how profits are taxed.

Step 2: Gather Financial Records

• Income statements, bank statements, and expense receipts
• Payroll records if you have employees
• Details of investments or business assets

Maintaining organized financial records ensures accurate reporting and reduces audit risk.

Step 3: Identify Applicable Tax Forms

• Single-member LLC: Schedule C attached to Form 1040
• Multi-member LLC: Form 1065, Schedule K-1 for members
• LLC electing S-Corp: Form 1120S
• LLC electing C-Corp: Form 1120

State taxes may require additional forms, such as sales tax or franchise tax returns.

Step 4: Calculate Deductions and Credits

• Business expenses: office rent, software subscriptions, marketing costs
• Home office deductions for eligible owners
• Vehicle and travel expenses related to business operations

Step 5: File Federal and State Returns
