What is a Schedule C?

A Schedule C is an IRS tax form that sole proprietors, freelancers, and independent contractors use to report the profit or loss from a business they operate. Its official name is "Profit or Loss from Business (Form 1040)," and it's one of the most common forms for self-employed individuals in the United States.

You use Schedule C to calculate your net business income by subtracting your business expenses from your gross income. The result, whether a profit or a loss, then flows onto your personal Form 1040 tax return. This means your business earnings are taxed as part of your individual income.

If you run a side business, do freelance work, or earn income as an independent contractor, you'll likely need to file a Schedule C. Even small amounts of self-employment income may require this form.

Who should file a Schedule C?

Anyone who operates a business as a sole proprietor or receives income as an independent contractor should file a Schedule C. This applies whether your business is a full-time venture or a side hustle you run on evenings and weekends.

The following types of business owners and self-employed individuals typically file a Schedule C:

Sole proprietors
Single-member LLCs (taxed as a disregarded entity)
Freelancers and independent contractors
Gig workers (rideshare drivers, delivery workers, and similar roles)
Side business owners who earn self-employment income

Some business structures don't use Schedule C. If you operate as a C corporation, S corporation, partnership, or multi-member LLC, you'll file different tax forms specific to those entity types.

Here's a closer look at two of the most common business types that file Schedule C.

Sole proprietorships

A sole proprietorship is the simplest business structure and doesn't require formal registration with the state. If you earn income from self-employment and haven't formed a separate business entity, the IRS considers you a sole proprietor by default.

You need to report all self-employment income on Schedule C, even if it comes from odd jobs, occasional freelance projects, or part-time gig work. There's no minimum business size required to file this form.

If your business is structured as an LLC, the rules depend on how you've chosen to be taxed.

Limited liability company (LLC)

If you operate a single-member LLC, the IRS treats it as a "disregarded entity" for tax purposes. This means you report your business income and expenses on Schedule C, just like a sole proprietor. You can learn more about what an LLC is and how it differs from other structures.

However, if your LLC elects to be taxed as an S corporation or C corporation, you won't use Schedule C. Instead, you'll file the appropriate corporate tax forms. For a detailed comparison, see this guide on S corp vs LLC structures. You can also review the IRS guidance on single-member limited liability companies for more details.

Information you provide on Schedule C

Schedule C asks for details about your business, your income, your expenses, and your cost of goods sold. Each section plays a role in calculating your net profit or loss for the tax year.

The form starts with basic identifying information about you and your business.

Details about your business

The top of Schedule C collects basic information about you and your business. You'll provide your name as the proprietor, your business name (if different), your business address, and your Employer Identification Number (EIN) if you have one.

You'll also select a principal business code from the North American Industry Classification System (NAICS). This 6-digit code tells the IRS what type of business you run. Choosing the right code helps ensure your return is categorized correctly.

After your business details, you'll move on to reporting your revenue.

Income

The income section is where you report what your business earned during the tax year. You'll enter your gross receipts or sales, then subtract any returns and allowances.

If your business sells products, you'll also subtract the cost of goods sold (COGS) to arrive at your gross profit. Add any other business income, such as recovered bad debts or interest on business accounts, to calculate your total gross income.

Next, you'll report the costs of running your business.

Expenses

Schedule C includes a list of common business expense categories you can deduct. Tracking these expenses throughout the year helps ensure you don't miss any eligible deductions.

Common expense categories on Schedule C include:

Advertising and marketing
Car and truck expenses
Insurance premiums (other than health)
Legal and professional services
Office expenses and supplies
Rent or lease payments
Repairs and maintenance
Utilities and phone costs
Travel and meals (subject to IRS limits)
Contract labor

Keeping accurate records of each expense, with receipts and documentation, makes filing easier and supports your deductions if the IRS has questions. Consider using tools that help you track your business expenses throughout the year.

Not every business needs to complete this next section, but if you sell physical products, it's required.

Cost of goods sold

If your business sells physical products, you'll complete the cost of goods sold (COGS) section on Schedule C. COGS includes the direct costs of producing or purchasing the goods you sold during the tax year.

This typically covers raw materials, direct labor costs, and the cost of inventory. You'll calculate COGS by adding your beginning inventory to purchases made during the year, then subtracting your ending inventory.

If you drive for business, you can also claim vehicle-related costs on Schedule C.

Vehicle expenses and depreciation

If you use a vehicle for business purposes, you have two methods for calculating your deduction. The standard mileage rate for 2025 is 70 cents per mile for business-related driving. You multiply your total business miles by this rate to determine your deduction.

The actual expense method lets you deduct the real costs of operating your vehicle for business, including gas, oil, repairs, insurance, and depreciation. You'll need to track the percentage of time you use the vehicle for business vs personal use.

For depreciating business assets, including vehicles, you may need to complete Form 4562. The IRS provides standard mileage rates each year, so confirm you're using the correct rate when filing.

Schedule C deductions that reduce your tax bill

Every eligible business expense you claim on Schedule C reduces your taxable income, which means you pay less in taxes. Understanding which deductions are available can help you keep more of what you earn.

Some of the most valuable deductions for self-employed individuals include:

Home office deduction: claim a portion of your rent, mortgage interest, utilities, and insurance based on the space you use exclusively for business
Vehicle expenses: deduct business mileage at 70 cents per mile or use the actual expense method
Advertising and marketing costs: website hosting, social media ads, business cards, and similar promotional expenses
Insurance premiums: business liability insurance, professional indemnity insurance, and similar coverage
Professional services: fees paid to accountants, attorneys, or consultants for business-related work
Supplies and equipment: office supplies, software subscriptions, and tools you use in your business

Self-employment tax and Schedule SE

If your net self-employment income is $400 or more, you owe self-employment tax at a combined rate of 15.3%. This tax covers your contributions to Social Security (12.4%) and Medicare (2.9%), similar to the payroll taxes employees and employers split.

As a self-employed individual, you're responsible for both the employer and employee portions of these taxes. You report and calculate self-employment tax on Schedule SE (Form 1040), which uses the net profit from your Schedule C.

The good news is that you can deduct half of your self-employment tax on your Form 1040. This deduction reduces your adjusted gross income, even if you don't itemize deductions. For additional resources, the IRS provides a self-employed individuals tax center with guidance on payments, credits, and filing requirements. You can also learn more about how self-employment tax works and what it means for your bottom line.

How to file a Schedule C

Filing your Schedule C involves completing the form and attaching it to your personal Form 1040 tax return. You can file electronically using tax preparation software or submit paper forms by mail.

Here are the steps to follow when filing your Schedule C:

Gather your business income records, including 1099-NEC forms from clients and any other payment documentation
Organize your business expense receipts and records by category
Complete each section of Schedule C: business information, income, expenses, cost of goods sold (if applicable), and vehicle information (if applicable)
Calculate your net profit or loss by subtracting total expenses from gross income
Transfer your net profit or loss to your Form 1040
Complete any additional required forms

Depending on your situation, you may also need to file these forms alongside your Schedule C:

Schedule SE: to calculate self-employment tax
Form 4562: to report depreciation and amortization of business assets
Form 8829: to claim the home office deduction using the actual expense method

E-filing through tax software is the fastest way to submit your return and tends to reduce errors. If you prefer, you can also print and mail your completed forms to the IRS.

Where to find Schedule C forms

You can download Schedule C and its instructions directly from the IRS website. The form is available as a PDF that you can fill in digitally or print and complete by hand.

Visit the official IRS page for Schedule C (Form 1040) to access the latest version of the form and detailed line-by-line instructions. Most tax preparation software also includes Schedule C as part of its self-employment filing workflow.

Schedule C deadlines and filing timeline

The standard deadline to file your Schedule C (along with your Form 1040) is April 15 each year. If April 15 falls on a weekend or holiday, the deadline shifts to the next business day.

You can request an automatic 6-month extension by filing Form 4868, which pushes your filing deadline to October 15. However, an extension to file isn't an extension to pay. You still need to estimate and pay any taxes you owe by the original April 15 deadline to avoid interest and penalties.

If you expect to owe $1,000 or more in taxes for the year, the IRS requires you to make quarterly estimated tax payments. These are due on April 15, June 15, September 15, and January 15 of the following year.

Home office deduction for Schedule C filers

If you use part of your home regularly and exclusively for business, you may qualify for the home office deduction. This deduction can significantly reduce your taxable income, especially if you work from home full time.

To qualify, the space must be your principal place of business or a place where you regularly meet clients. It needs to be used exclusively for business, meaning a guest bedroom that doubles as an office may not qualify.

You can calculate the deduction using one of two methods:

Simplified method: deduct $5 per square foot of your home office, up to a maximum of 300 square feet. This gives you a maximum deduction of $1,500 with less paperwork
Actual expense method: calculate the percentage of your home used for business, then apply that percentage to actual home expenses like mortgage interest, rent, utilities, insurance, and repairs. You'll need to complete Form 8829

The simplified method works well if your home office is small or you want a straightforward calculation. The actual expense method may give you a larger deduction if your home expenses are high. The IRS provides detailed guidance on the home office deduction to help you choose the right approach.

Common Schedule C mistakes to avoid

Filing your Schedule C accurately helps you avoid delays, penalties, and potential audits. Here are some of the most common mistakes to watch for.

Many self-employed individuals make these errors when preparing their Schedule C:

Mixing business and personal expenses: keep your business and personal finances separate. Use a dedicated business bank account and track every transaction
Forgetting eligible deductions: review the full list of deductible expenses before filing. Missing even one category can increase your tax bill unnecessarily
Incorrectly reporting income: make sure your reported income matches the 1099-NEC forms your clients submit. The IRS cross-references these numbers
Making vehicle expense calculation errors: pick either the standard mileage rate or the actual expense method and apply it consistently. You can't switch between methods mid-year for the same vehicle
Not tracking home office expenses: if you claim the actual expense method, keep records of your mortgage or rent, utilities, and repairs throughout the year
Choosing the wrong accounting method: decide whether cash basis or accrual basis accounting makes sense for your business, and apply the same method consistently each year

Schedule C vs other tax forms

Different types of income require different IRS forms. Here's how Schedule C compares to other common tax forms you might encounter.

Schedule C vs Schedule E (rental income):

Schedule C reports income from a business you actively operate
Schedule E reports passive income from rental properties, royalties, or partnerships
If you provide substantial services to tenants (like a bed and breakfast), that income may belong on Schedule C instead

Schedule C vs Schedule F (farming):

Schedule C covers most types of self-employment income
Schedule F is specifically for farming income and expenses
If your primary business is farming, you'll use Schedule F rather than Schedule C

Schedule C vs W-2 (employee income):

Schedule C is for self-employed individuals who control how and when they work
A W-2 reports wages earned as an employee, where your employer withholds taxes on your behalf
If you have both employment and self-employment income, you'll file a W-2 for your job and a Schedule C for your business

Choosing the right form depends on the type of income you earn and your business structure. If you're comparing an LLC to a sole proprietorship, the structure you choose may also affect which forms you need.

FAQs on Schedule C

Here are answers to some of the most common questions about filing a Schedule C tax form.

Do I need to file a Schedule C with no income?

You can file a Schedule C even if your business earned no income during the tax year. Reporting a loss can offset other income on your Form 1040 and potentially reduce your overall tax bill. If you had business expenses but no revenue, filing Schedule C lets you claim those losses.

Do I have to file a Schedule C if I receive a 1099-NEC?

Receiving a 1099-NEC form typically means you earned self-employment income that should be reported on Schedule C. The 1099-NEC reports nonemployee compensation, and the IRS expects you to include this income on your tax return along with any related business expenses.

Does an LLC file a Schedule C?

A single-member LLC that hasn't elected corporate tax treatment files a Schedule C, since the IRS treats it as a disregarded entity. If your LLC has multiple members or has elected to be taxed as an S corporation, you'll use different tax forms instead.

What is the minimum income to file a Schedule C?

There's no minimum income threshold for filing Schedule C itself. However, if your net self-employment earnings reach $400 or more, you're required to file a tax return and pay self-employment tax. Even below $400, you may still want to file to report losses or claim deductions.

How do I determine my vehicle expenses?

You can choose between the standard mileage rate (70 cents per mile for 2025) or the actual expense method, which includes gas, repairs, insurance, and depreciation. Track your business miles carefully throughout the year, and keep a log that separates business use from personal use.

What happens if I don't file a Schedule C?

Failing to file a Schedule C when you owe self-employment tax can result in IRS penalties and interest on unpaid taxes. The IRS may also assess taxes based on income reported by your clients on 1099-NEC forms, without accounting for your deductions. Filing on time, even if you need to request an extension, helps you avoid these issues and claim every deduction you're entitled to.
