Learning how to file taxes self-employed or as a freelancer involves more than reporting the payments you received. You also need to calculate business expenses, determine net profit and understand whether self-employment tax and estimated tax payments apply.
Independent contractors and sole proprietors generally report business income and expenses on Schedule C. In addition, taxpayers with sufficient net earnings from self-employment generally use Schedule SE to calculate Social Security and Medicare taxes.
Therefore, good bookkeeping throughout the year can make tax preparation much easier. Organized records can also help you identify legitimate business expenses and avoid overlooking taxable income.
SELF-EMPLOYED TAX BASICS
When You Work for Yourself, You Handle More of the Tax Process
Employees typically receive wages after their employer withholds federal income tax and the employee’s share of Social Security and Medicare taxes. Self-employment works differently.
Independent contractors generally receive payments without regular federal income tax withholding. As a result, they need to track their own income, business expenses and potential tax obligations.
For a typical sole proprietor, Schedule C is used to determine the profit or loss from the business. That net result then becomes important for both income tax and self-employment tax calculations.
Consequently, knowing your gross revenue alone is not enough. Your business records need to show the complete financial activity of your freelance or self-employed work.
THE BASIC FLOW
Income − expenses = profit.
Your net business profit is a key number on your tax return.
Accurate income and expense records help support the numbers reported on Schedule C.
SCHEDULE C
Where Self-Employed Income Is Generally Reported
Sole proprietors and independent contractors generally use Schedule C to report income and expenses from a trade or business.
The form helps determine the business’s net profit or loss.
01
Report Business Income
Start with income from your self-employed activity. This can include payments reported on Forms 1099-NEC or 1099-K as well as business income for which you did not receive an information return.
02
Report Eligible Business Expenses
Next, report qualifying expenses associated with operating the business. The specific deductions depend on the nature of your work and the expenses you actually incurred.
03
Determine Net Profit or Loss
Schedule C calculates the net result of the business. That amount generally flows into the individual income tax return and can also affect the self-employment tax calculation.
REPORT ALL INCOME
Do You Report Income if You Didn’t Receive a 1099?
Yes. Receiving an information form and having taxable business income are two separate issues.
1099-NEC and Other Tax Forms
Independent contractors commonly receive Form 1099-NEC for nonemployee compensation. Depending on the activity and payment method, other information returns may also be issued.
Use these forms when reconciling your business records. However, do not assume that the total from your tax forms automatically equals your complete business income.
Instead, compare the forms with invoices, bank deposits, payment processor reports and your bookkeeping records.
No Form Does Not Mean No Income
Business income generally remains reportable even when a client or customer does not send you a Form 1099.
For example, direct payments from customers may still represent taxable business income even when no information return was issued.
Therefore, self-employed taxpayers should maintain their own complete income records rather than relying exclusively on the forms received at tax time.
SELF-EMPLOYMENT TAX
What Is Self-Employment Tax?
Self-employment tax primarily covers Social Security and Medicare taxes for individuals who work for themselves.
If your net earnings from self-employment from all applicable businesses are $400 or more, you generally use Schedule SE to calculate self-employment tax.
The self-employment tax rate is generally 15.3%, consisting of a 12.4% Social Security portion and a 2.9% Medicare portion. However, the calculation is not simply 15.3% of the gross revenue shown by your business.
Instead, Schedule SE applies the applicable calculation to net earnings from self-employment. Social Security wage-base rules and Additional Medicare Tax rules can also become relevant depending on your income and circumstances.
In addition, an income-tax deduction is generally available for the deductible portion of self-employment tax. This deduction affects income tax, but it does not eliminate the self-employment tax itself.
IMPORTANT THRESHOLD
$400+
in net earnings from self-employment generally triggers Schedule SE.
This threshold refers to net earnings from self-employment, not simply the amount shown on one Form 1099.
BUSINESS DEDUCTIONS
Don’t Overlook Legitimate Business Expenses
Business deductions can reduce the net profit subject to federal income tax and, in many cases, the amount entering the self-employment tax calculation.
However, expenses must meet the applicable tax requirements and should be supported by adequate records.
Supplies & Business Costs
Depending on your work, qualifying expenses can include supplies, software, professional services, advertising and other costs associated with operating your business.
Vehicle Expenses
Business use of a vehicle may create a deduction when the applicable requirements are satisfied. However, commuting between your home and regular workplace is generally personal rather than deductible business mileage.
Business Use of Home
A home office deduction may be available when part of the home meets the applicable business-use requirements. Simply working from home occasionally does not automatically make household expenses deductible.
Insurance & Professional Expenses
Certain business insurance, professional fees and other ordinary business costs can also be deductible. Therefore, categorize expenses throughout the year instead of trying to reconstruct them from memory during tax season.
BUSINESS VS. PERSONAL
Separate Business Expenses From Personal Spending
One of the simplest ways to improve self-employed bookkeeping is to keep business activity clearly separated from personal transactions.
Use Organized Financial Records
A separate business bank account can make it easier to identify business revenue and expenses, even when your tax classification does not legally require a separate account.
In addition, regularly categorizing transactions reduces the amount of cleanup needed at year-end.
Keep invoices, receipts and other documentation that supports the amounts entered in your books and tax return.
Allocate Mixed-Use Costs Carefully
Some expenses have both business and personal components. A phone, internet connection or vehicle, for example, may be used for both purposes.
Therefore, do not automatically deduct the full cost simply because the item is sometimes used for work.
Instead, determine the allowable business portion using the applicable tax rules and maintain records that support the allocation.
ESTIMATED TAXES
Don’t Wait Until Tax Season to Think About Payments
The U.S. federal tax system generally operates on a pay-as-you-go basis.
Since self-employed workers typically do not have an employer withholding taxes from business payments, estimated payments may be necessary.
Who May Need Estimated Payments?
Whether estimated payments are required depends on the amount of tax you expect to owe and the applicable federal rules. Therefore, having freelance income does not automatically mean that every taxpayer pays the same quarterly amount.
Four Payment Periods
Federal estimated taxes generally have four payment periods during the year. The usual due dates fall in April, June, September and January, although weekends and legal holidays can move a deadline.
Income Can Change During the Year
Freelance income often fluctuates. Consequently, taxpayers may need to review their estimated tax position during the year rather than assuming one calculation will remain accurate forever.
RECORDKEEPING
Good Tax Preparation Starts Before the End of the Year
Self-employed taxpayers should maintain records that clearly show business income and expenses. Waiting until tax season to reconstruct a year of transactions can create unnecessary problems.
First, reconcile the income shown in your bookkeeping with bank accounts, payment platforms and applicable Forms 1099. Next, review expense categories and investigate transactions that are unclear.
In addition, maintain supporting documentation for major purchases, vehicle use, home-office calculations and other deductions that require additional information.
Consistent bookkeeping also helps you understand how the business is performing. ASB Tax & Accounting offers bookkeeping services for self-employed individuals and business owners who need help keeping their records organized.

SIDE JOBS COUNT TOO
What if Freelancing Is Only a Side Business?
Self-employment tax rules are not limited to people who work for themselves full time.
Part-time, temporary and gig work can still create tax obligations.
You Can Have a W-2 and Schedule C
A taxpayer can be an employee at one job and operate a separate freelance business at the same time. In that situation, W-2 wages and self-employed business activity are reported under their respective rules.
Your Side Income Is Still Relevant
Calling an activity a “side hustle” does not automatically make its income tax-free. If the activity constitutes a business, its income and qualifying expenses generally need to be reported accordingly.
Withholding Can Affect Estimated Taxes
If you also have a W-2 job, withholding from your wages can affect whether additional estimated tax payments are necessary. Therefore, review the complete tax picture rather than analyzing the freelance activity in isolation.
COMMON QUESTIONS
FAQ About Filing Taxes When Self-Employed
These answers cover several common federal tax questions for freelancers, sole proprietors and independent contractors.
Generally, yes. Business income does not become tax-free simply because a payer did not issue an information return. Therefore, use your own business records to report applicable income, including amounts not shown on a Form 1099.
Sole proprietors and independent contractors generally report business income and expenses on Schedule C attached to their individual tax return. Schedule SE is generally used to calculate self-employment tax when the applicable requirements are met.
Generally, Schedule SE and self-employment tax apply when your net earnings from self-employment are $400 or more, subject to applicable rules and exceptions. The tax primarily covers Social Security and Medicare taxes.
Qualifying business expenses can generally reduce Schedule C profit when they meet the applicable tax requirements. However, personal expenses are not converted into business deductions simply because you are self-employed. Maintain records supporting the business purpose and amount of each deduction.
Some freelancers and self-employed taxpayers need to make estimated tax payments because taxes are not normally withheld from their business income. Whether payments are required and how much to pay depend on the taxpayer’s expected tax liability and other circumstances.
