If you are filing business taxes for LLC for the first time, you are in the right place. Navigating small business taxes can feel overwhelming, but the process is much more manageable when you start with the right foundation. That means having a properly formed LLC before you ever touch a tax form.
Not sure what formation costs? See our full breakdown of LLC startup costs in 2026, or use our free LLC name search tool to check availability before you register.
Step 1 — Choose Your Tax Classification
The biggest thing beginners miss when filing business taxes for an LLC for the first time: an LLC has no fixed tax treatment. The IRS lets you choose how your LLC is taxed, and that choice determines everything — which form you file, what you owe, and what you can deduct.
| LLC Type | Default Tax Treatment | Tax Form |
|---|---|---|
| Single-Member LLC | Sole proprietorship | Schedule C (Form 1040) |
| Multi-Member LLC | Partnership | Form 1065 |
| S-Corp Election | S-Corporation | Form 1120-S |
| C-Corp Election | C-Corporation | Form 1120 |
Most first-time filers operate as a single-member LLC, which is the simplest path. You report business income on Schedule C and attach it to your personal tax return. Not yet sure which state to form in? Read our guide on the best states to form an LLC as a non-resident.
Form Your LLC the Right Way Before You File
Trying to file taxes for an LLC that isn’t properly registered causes expensive problems. Tailor Brands sets up your LLC correctly across all 50 states — registered agent, operating agreement, EIN, and more.

Step 2 — Gather Your Financial Records
Your tax bill is based on profit, not gross income. That means every legitimate business expense you document reduces what you owe. Before you open any tax software, collect:
- All income sources (invoices, PayPal/Stripe statements, 1099 forms)
- Business expense receipts
- Bank and credit card statements
- Mileage log (if you drove for business)
- Home office measurements (if applicable)
- Payroll records (if you have employees)
Step 3 — Use the Correct LLC Tax Filing Form
Using the wrong form is one of the most common mistakes when filing business taxes for an LLC. Here is exactly what you need based on your structure:
| LLC Structure | Form to File | Due Date |
|---|---|---|
| Single-Member LLC | Schedule C attached to Form 1040 | April 15 |
| Multi-Member LLC | Form 1065 (Partnership Return) | March 15 |
| LLC taxed as S-Corp | Form 1120-S | March 15 |
| LLC taxed as C-Corp | Form 1120 | April 15 |
Step 4 — Calculate Your Income and Deductions
You only pay tax on net profit. The IRS allows a wide range of deductions for legitimate business expenses to lower your small business taxes. Here are the most commonly missed:
Commonly Overlooked LLC Tax Deductions
- Business software subscriptions (QuickBooks, Zoom, Canva, etc.)
- LLC formation and registered agent fees
- Business-related phone and internet costs
- Home office deduction (dedicated workspace only)
- Business mileage ($0.70/mile in 2026)
- Professional development, courses, and books
- Marketing, advertising, and website costs
- Health insurance premiums (self-employed)
Step 5 — File Your LLC Taxes
You have three main options for actually submitting your LLC tax return:
Option 1: Tax Software (Best for Simple LLCs)
Tools like TurboTax, TaxAct, or FreeTaxUSA walk you through the process step by step and handle Schedule C automatically. This is ideal for single-member LLCs with straightforward income and expenses.
Option 2: IRS Free File
If your adjusted gross income is under the annual threshold, you may qualify for free federal filing directly at irs.gov/freefile. Note that state returns are typically separate.
Option 3: Hire a CPA or Tax Professional
Recommended if you have a multi-member LLC, multiple income streams, S-Corp election, or significant revenue. The cost of a CPA is itself a deductible business expense.
What If Your LLC Made $0 This Year?
This is one of the most searched questions for new business owners — and the answer surprises many beginners.
Multi-member LLCs: YES, always. Form 1065 is required regardless of income.
Single-member LLCs: It depends. Technically not always required, but filing a zero-income return is strongly recommended to stay compliant, maintain your LLC in good standing, and avoid questions from the IRS later.
Failing to file when required results in automatic penalties — currently $235 per partner per month for Form 1065 late filings. Filing a zero-income return costs you nothing but protects you from significant fines. If you’re a foreign owner of a US LLC, the penalties are even steeper — see our guide to late filing penalties for foreign-owned LLCs.

Common Mistakes to Avoid
- Mixing personal and business finances in the same account
- Missing the March 15 deadline for multi-member LLCs
- Filing zero-income returns as “not required” (risky for multi-member LLCs)
- Forgetting self-employment tax (15.3% on net earnings)
- Not tracking expenses throughout the year (scrambling at tax time)
- Using the wrong tax form for your LLC classification
- Ignoring quarterly estimated tax payments if you expect to owe $1,000+
