Schedule C is where many self-employed taxpayers report the income and expenses of a sole proprietorship. If you freelance, run a side business, work as an independent contractor, or own a single-member LLC that is treated as a sole proprietorship for federal tax purposes, this form helps determine your business profit or loss for the year.
This guide explains who generally uses Schedule C, what to gather before you begin, and how to complete each part of the form. It also shows where the result goes next, so you can prepare your return with clearer records and fewer surprises.
What is Schedule C?
Schedule C (Form 1040), Profit or Loss From Business (Sole Proprietorship), is an attachment to your federal income tax return. You use it to report the income you earned from a business you operated or a profession you practiced as a sole proprietor, then subtract eligible business expenses to arrive at a net profit or loss.
For many taxpayers, that number flows to Schedule 1 of Form 1040. A net profit may also be used on Schedule SE to figure self-employment tax. Schedule C does not replace Form 1040; it supplies the business-income details that support your individual tax return.
Who needs to file Schedule C?
You may need Schedule C if you had income from a business activity you operated as a sole proprietor. Generally, the activity must be carried on for income or profit with continuity and regularity. Common examples include freelancers, consultants, creators, gig workers, independent contractors, and owners of single-member LLCs that have not elected corporate tax treatment.
Schedule C can also apply in certain other situations, including statutory employee income and qualified joint ventures. If you operate more than one distinct business, the IRS generally requires a separate Schedule C for each business. Partnerships generally file Form 1065 instead, so business structure matters.
What you need before filling out Schedule C
Gather your records before you start. This helps you match form entries to the documents that support them and prevents common omissions.
- Your legal name, Social Security number, and business name and EIN, if applicable
- Your principal business activity, product or service, and the applicable six-digit business code
- Income records, such as invoices, sales reports, bank records, and Forms 1099-NEC, 1099-K, or 1099-MISC you received, plus records of business income not reported on a Form 1099
- Receipts and account statements for ordinary and necessary business expenses
- Inventory records if you sell products
- Mileage logs and vehicle records if you claim car or truck expenses
- Home-office information if you plan to claim a business-use-of-home deduction
Keep personal and business expenses separate. An expense generally needs to be ordinary and necessary for your business to be deductible; documentation also matters if the IRS asks you to substantiate an entry.

How to fill out Schedule C, step by step
Step 1: Complete the business information at the top
Enter the proprietor’s name and SSN, then describe your principal business or profession in line A. Be specific about the service or product that produced your primary business income. On line B, select the six-digit principal business or professional activity code from the IRS instructions.
Add the business name only if you use a separate one, along with an EIN if you have one. Then enter the business address and accounting method, answer the material-participation question, and complete lines I and J regarding payments that may require you to file Forms 1099. If you started or acquired the business during the tax year, check the box on line H.
Step 2: Report business income in Part I
Line 1 is for gross receipts or sales. Report the income your business received or earned under your accounting method; do not reduce it by expenses here. Enter returns and allowances on line 2, then subtract them on line 3.
If your business sells merchandise, enter the cost of goods sold from Part III on line 4. Line 5 is your gross profit. Use line 6 for other income not already reported in Part I, and add lines 5 and 6 to calculate gross income on line 7.
Step 3: Enter business expenses in Part II
Part II is for expenses that belong to the business, such as advertising, insurance other than health insurance, legal and professional services, office expenses, supplies, utilities, and eligible travel. Use the specific line that best fits the expense instead of listing the same cost in more than one place.
Car and truck expenses go on line 9. The rules differ depending on whether you use the standard mileage rate or actual expenses, and you will need supporting mileage records. For more detail, consult IRS Publication 463 before claiming travel, meals, gifts, or vehicle expenses.
Enter expenses for business use of your home only on line 30. You may need to attach Form 8829 unless you use the simplified method. Jotform’s Form 8829 Generator can help you prepare the related form online.
After you total lines 8 through 27b on line 28, subtract that amount from line 7 to calculate tentative profit or loss on line 29. Do not treat personal, living, or family costs as business expenses.
Step 4: Calculate home-office expenses and net profit or loss
Complete line 30 only for allowable business-use-of-home expenses. Then subtract line 30 from line 29 to calculate line 31, your net profit or loss. A profit is generally reported on Schedule 1, line 3, and Schedule SE, line 2. A loss may be limited by at-risk, passive-activity, or excess business loss rules, so review line 32 and the official instructions carefully before reporting it.
Step 5: Complete Part III to calculate cost of goods sold, if applicable
Part III generally applies when you the production, purchase, or sale of merchandise is an income-producing factor. Select your inventory valuation method, indicate whether there was a change in how quantities or values were determined, and enter beginning inventory, purchases, labor, materials and supplies, other costs, and ending inventory. The result on line 42 carries to Part I, line 4.
If you do not sell products, this part may not apply. Inventory accounting can be complex, especially if you change methods, so consult the IRS instructions or a qualified tax professional when needed.
Step 6: Complete Part IV for vehicle information, if required
Complete Part IV if you claim the standard mileage rate, lease the vehicle, or the vehicle is fully depreciated and you are not required to file Form 4562 for another reason. You will enter the date the vehicle was placed in service, business, commuting, and other miles, plus answers about personal use and your written evidence. Keep your mileage log and receipts with your tax records.
Step 7: List other expenses in Part V
Use Part V for ordinary and necessary business expenses that do not fit lines 8 through 27a or line 30. List each type separately, total the amounts on line 48, and carry that total to line 27b. Do not use this section to report equipment purchases, permanent improvements, personal costs, charitable contributions, or government fines and penalties.
