If you earn money as a freelancer or independent contractor, Schedule C is the most important tax form you’ll file. It’s also the one that scares first-timers the most. The form looks long and uses unfamiliar terms like «cost of goods sold» and «principal business code.»
The good news is that most freelancers only use a handful of lines. This guide explains what Schedule C is, what to gather before you start, and how to complete each part in plain English.
What Is Schedule C?
Schedule C, officially «Profit or Loss From Business,» is the form where sole proprietors and single-member LLCs report business income and business expenses. It is not a separate tax return. You attach it to your Form 1040.
The result at the bottom of the form, your net profit or loss, does two jobs:
- It becomes part of your income for income tax.
- It is used to calculate self-employment tax on Schedule SE. See our guide to self-employment tax explained for how that works.
Who Needs to File Schedule C?
You generally use Schedule C if you run a business as a sole proprietor or a single-member LLC, whether it’s your main job or a side hustle. If you’re unsure about your business structure, our article on sole proprietor vs. LLC can help.
Rental income, partnership income, and S-corp income are usually reported on different forms.
What to Gather Before You Start
Having everything in front of you makes the form much easier. Collect:
- Income records: invoices, bank statements, payment platform reports, and any 1099 forms (see when freelancers get a 1099-NEC and 1099-NEC vs. 1099-K)
- Expense records: receipts, credit card statements, and software or subscription bills
- Business details: your business name (if any), address, and EIN if you have one (see how to get an EIN)
- Mileage log, if you drive for work (see how to track mileage)
If your records are scattered, set up a simple bookkeeping system first. It will save you hours.
How Schedule C Is Organized
The form has five parts:
| Part | What it covers |
| Top of the form | Your business information |
| Part I | Income |
| Part II | Expenses |
| Part III | Cost of goods sold (only if you sell products) |
| Part IV | Vehicle information |
| Part V | Other expenses |
Most service-based freelancers will mainly use the top section, Part I, Part II, and sometimes Parts IV and V.
Step 1: Fill In Your Business Information
At the top of the form, you’ll enter:
- Your name and Social Security number (or other taxpayer ID)
- Principal business or profession: a simple description, such as «freelance graphic design»
- Business code: a six-digit code from the chart in the IRS Schedule C instructions
- Business name: only if you operate under one, otherwise leave it blank
- EIN: only if you have one
- Business address
- Accounting method: most freelancers use the cash method, which means you count income when you receive it and expenses when you pay them
- Questions about 1099 forms: the form asks whether you made payments that required you to file 1099s, and whether you did. Check the current instructions for the exact rules.
Step 2: Report Your Income (Part I)
Part I is where you report your gross income, meaning what you earned before expenses.
- Line 1, gross receipts or sales: enter your total business income for the year. Include all of it, not just what appeared on 1099 forms.
- Returns and allowances: subtract refunds you gave to customers, if any.
- Other income: enter business income that doesn’t belong on the earlier lines.
- Gross income: the form guides you through the calculation.
Common mistake: copying only the amounts from 1099s. Your records, not the forms, determine your income. Cash, checks, transfers, and smaller clients all count.
Step 3: Add Up Your Business Expenses (Part II)
Part II is where you subtract the ordinary and necessary costs of running your business. Most freelancers will use some of these lines:
| Line | Expense | Examples |
| 8 | Advertising | Ads, website promotion, business cards |
| 9 | Car and truck expenses | Business mileage or actual vehicle costs |
| 11 | Contract labor | Subcontractors or helpers you paid |
| 13 | Depreciation | Computers and equipment (may need Form 4562) |
| 15 | Insurance (other than health) | Business liability insurance |
| 16 | Interest | Business loan or business credit card interest |
| 17 | Legal and professional services | Accountant or attorney fees |
| 18 | Office expense | Small office items and postage |
| 22 | Supplies | Materials you use up in your work |
| 23 | Taxes and licenses | Business licenses and permits |
| 24 | Travel and meals | Business travel and qualifying meals |
| 25 | Utilities | Business phone and internet, in proportion to business use |
| 27 | Other expenses | Software, subscriptions, fees (details go in Part V) |
A few quick rules:
- Keep records. Receipts, statements, and invoices are your proof.
- Only deduct business use. If something is used for both personal and business purposes, deduct only the business share.
- Some deductions live elsewhere. Self-employed health insurance and retirement plan contributions are generally taken on Schedule 1, not on Schedule C.

Step 4: Handle the Home Office Deduction
If you work from a dedicated space at home, there’s a line near the bottom of Part II for business use of your home. You can calculate it using either the simplified method or the regular method, which uses Form 8829. The space generally must be used regularly and exclusively for business. Our guide on the home office deduction explains the rules.
Step 5: Find Your Net Profit or Loss
The net profit or loss line is the bottom line of the form. It’s your income minus your expenses (and any home office deduction).
- Net profit: this amount is subject to income tax and, in most cases, self-employment tax.
- Net loss: you may be able to use it to offset other income, but limits can apply. If you’re unsure, ask a tax professional.
Your net profit flows to Schedule 1 (and from there to Form 1040) and to Schedule SE, where you calculate self-employment tax.
Step 6: Complete the Other Parts If They Apply
- Part III, cost of goods sold: only for businesses that make or buy products to sell. Most service freelancers skip it.
- Part IV, vehicle information: if you claim car or truck expenses, you’ll answer questions such as when you started using the vehicle for business and your business, commuting, and personal miles.
- Part V, other expenses: list expense types that don’t fit elsewhere, such as software subscriptions, bank fees, or professional dues, and give the total.
Step 7: Double-Check Before You File
Before you finish, review:
- Does your income total match your own records, not just your 1099s?
- Is each expense in the right category and backed by documentation?
- Did you subtract refunds and avoid counting any payment twice?
- Is your name, taxpayer ID, and business information accurate?
- Did you complete Schedule SE and attach everything to your Form 1040?

Common Schedule C Mistakes to Avoid
- Reporting only income shown on 1099 forms
- Mixing personal and business expenses
- Deducting 100% of something used partly for personal reasons
- Putting health insurance or retirement contributions on the wrong form
- Forgetting Schedule SE
- Guessing at amounts without records
Frequently Asked Questions
Do I need a business name or EIN to file Schedule C?
No. If you operate under your own name, you can leave the business name blank, and you can use your Social Security number unless you have an EIN.
Can I file Schedule C if I only made a little money?
Yes. Self-employment income generally has to be reported even if it’s small. Check the IRS rules for when self-employment tax applies.
What if I had a loss?
You still report it on Schedule C. A loss may reduce other income, but limits can apply, and the IRS expects the activity to be run as a real business.
Which Schedule C do I use for the 2026 tax year?
Use the 2026 version of the form and instructions when the IRS releases them, usually in late fall, since line details can change from year to year.
Final Thoughts
Schedule C is really just three steps: report your income, subtract your legitimate business expenses, and carry the profit to the rest of your return. Keep clean records all year and the form becomes far less intimidating.
