How to calculate and file self-em­ploy­ment taxes

Free­lanc­ing is a popular choice for many workers in the USA, but for tax purposes, there is no specific category for “free­lancer.” Instead, free­lancers typically file taxes as “self-employed” in­di­vid­u­als or “in­de­pen­dent con­trac­tors.” Depending on how you file, you may be subject to different taxes. However, all self-employed in­di­vid­u­als and in­de­pen­dent con­trac­tors are required to pay state and/or federal income tax and self-em­ploy­ment tax. Ad­di­tion­al taxes may apply depending on the nature of your business, which will be discussed later.

Which taxes apply to free­lancers?

Un­der­stand­ing the nuances of each tax type is crucial for main­tain­ing com­pli­ance and avoiding penalties. Free­lancers should keep detailed records of their income and expenses, and consult with a tax pro­fes­sion­al if they are unsure about their oblig­a­tions.

Income Tax

Free­lancers must pay federal income tax on their net earnings (total income minus allowable de­duc­tions). The rate varies based on income levels and filing status. The IRS uses a pro­gres­sive tax system, meaning the more you earn, the higher the rate you’ll pay on the income within each tax bracket.

In addition to federal income tax, free­lancers may also be subject to state income tax (depending on the state they live and work in). Some states, like Texas and Florida, do not impose a state income tax, while others, like Cal­i­for­nia and New York, have rel­a­tive­ly high state income taxes. Ad­di­tion­al­ly, some local ju­ris­dic­tions impose their own income taxes.

What to bear in mind:

• Free­lancers are re­spon­si­ble for cal­cu­lat­ing and paying their own income tax.
• Income tax is typically due on April 15th each year unless ex­ten­sions are filed.
• Quarterly estimated tax payments are required for those who expect to owe $1,000 or more in taxes for the year.

Self-Em­ploy­ment Tax

The self-em­ploy­ment tax covers the Social Security and Medicare con­tri­bu­tions that would typically be paid by an employer if the free­lancer were an employee. As a free­lancer, you’re con­sid­ered both the employer and the employee, so you pay the full amount (15.3%) on your net earnings.

This tax is divided into:

• 12.4% for Social Security (up to a certain income limit, which changes annually — for 2025, it’s $160,200).
• 2.9% for Medicare (with no income cap).
• An ad­di­tion­al 0.9% Medicare tax applies to income over $200,000 ($250,000 for married couples filing jointly).

Free­lancers must calculate their self-em­ploy­ment tax using Schedule SE when filing their income tax return. The self-em­ploy­ment tax is usually paid in addition to regular income tax.

What to bear in mind:

• This tax is cal­cu­lat­ed on net earnings (income after expenses).
• Free­lancers can deduct half of the self-em­ploy­ment tax when cal­cu­lat­ing their adjusted gross income, though they still pay the full amount.
• Self-em­ploy­ment tax applies to free­lancers who earn over $400 annually in net earnings from self-em­ploy­ment.

Sales Tax

Sales tax applies to certain goods and services. If you’re selling tangible products or providing taxable services, you may need to collect and remit sales tax to your state or local tax au­thor­i­ties. However, the ap­pli­ca­tion of sales tax to services varies widely by state, and not all freelance services are taxable.

For example:

• In Cal­i­for­nia, some pro­fes­sion­al services, like legal or ac­count­ing services, are exempt from sales tax, but tangible goods sold (e.g., product sales) are taxable.
• In New York, many types of services are also exempt, but things like software sales or digital products may be taxable.

Sales tax is generally charged as a per­cent­age of the sale price of goods or taxable services. Free­lancers must register with their state’s tax authority to collect sales tax, then remit the tax collected to the ap­pro­pri­ate state or local agency.

What to bear in mind:

• Sales tax applies dif­fer­ent­ly depending on the state, so it’s important to un­der­stand your state’s specific rules.
• If you sell goods or services to clients in multiple states, you may need to collect sales tax in each state where you have a “nexus” (a sig­nif­i­cant con­nec­tion, such as physical presence or sales thresh­olds).

Estimated Taxes

Free­lancers don’t have taxes au­to­mat­i­cal­ly withheld from their paychecks, so they must make estimated tax payments to cover their federal income tax and self-em­ploy­ment tax oblig­a­tions. The IRS expects free­lancers to make these payments quarterly, and they’re due on the 15th of April, June, September, and January of the following year.

Estimated taxes are based on your expected income for the year. To calculate your estimated tax payments, you can use IRS Form 1040-ES. If you don’t pay enough through estimated taxes, you could face penalties.

What to bear in mind:

• If you expect to owe $1,000 or more in taxes, you are generally required to make estimated payments.
• You can adjust your quarterly payments through­out the year if your income fluc­tu­ates.
• Failure to pay estimated taxes may result in penalties, so free­lancers must stay on top of their payments.

Other Taxes

Free­lancers may encounter ad­di­tion­al taxes depending on their type of work, their business structure, or the location of their business. Some of the common ad­di­tion­al taxes include:

• State and Local Business Taxes: Some states and cities impose business taxes in addition to income tax. For example, a state may have a flat business tax or a tax based on revenue or the number of employees.

• Un­em­ploy­ment Taxes: While free­lancers generally don’t pay into the un­em­ploy­ment system, certain free­lancers in specific in­dus­tries may be subject to un­em­ploy­ment taxes or may choose to pay into an un­em­ploy­ment insurance program vol­un­tar­i­ly.

• Excise Taxes: If a free­lancer works in a spe­cial­ized industry, like the sale of alcohol, tobacco, or gasoline, they may be subject to excise taxes, which are taxes on specific types of goods or services.

• Property Taxes: If a free­lancer owns property or equipment related to their business, they may need to pay property taxes based on the value of that property.

What to bear in mind:

• It’s important to check your state’s specific re­quire­ments for business taxes, as they can vary widely.
• If you have a business structure like an LLC or cor­po­ra­tion, there may be ad­di­tion­al tax re­spon­si­bil­i­ties.

How to file self-em­ploy­ment taxes step by step

If you are self-employed and want to file your own tax returns without the help of a tax pro­fes­sion­al, there are a few things to keep in mind. Simple tricks and tips can save a lot of work and stress at the end of the year. In the following step-by-step in­struc­tions, we explain how to calculate self-em­ploy­ment taxes correctly without too much effort.

Document revenues and ex­pen­di­ture

The most important thing when filing a self-em­ploy­ment tax return is to have a clear, com­pre­hen­sive overview of your financial year. While there is no law requiring business owners to keep book­keep­ing records, it is in their interest to adhere to Generally Accepted Ac­count­ing Prin­ci­ples (GAAP). This helps run the business smoothly, file taxes ef­fec­tive­ly, and explain them­selves in case of an IRS audit. The same applies to the self-employed. The clearer your records are through­out the year, the easier it will be to file your tax return at the end of the tax period.

As a rule, two simple Excel sheets are suf­fi­cient to document income and expenses: one for revenue and one for ex­pen­di­ture. These tables should include the date, service provider/sales­per­son, service or product de­scrip­tion, gross amount, and document reference number (for receipts or invoices kept as proof of purchase/sale) in separate columns. If you are also liable for sales tax, you can create columns for net amounts, sales tax, and cal­cu­lat­ed sales tax. This helps you keep track and saves work in the long run.

Collect and sort documents

Having revenue and expenses is one thing, but being able to keep track of them is another. Business ac­tiv­i­ties need to be doc­u­ment­ed, and it’s better to have too many records than too few. Sup­port­ing documents should include receipts for cash payments, transfer receipts, delivery notes, pay slips, fuel, and en­ter­tain­ment receipts.

While no specific law mandates the book­keep­ing system you use, it’s often easier and more accurate to use a digital filing system along with retaining paper receipts. A well-organized record-keeping system should allow you to add new documents to your database as you get them. Programs often create folders where documents are sys­tem­at­i­cal­ly filed.

If your business operates under the cash ac­count­ing method, then two core folders should usually suffice:

• Account statement folder, filed chrono­log­i­cal­ly; documents are filed behind each account statement.
• Folder for cash documents, se­quen­tial­ly organized by document number.

For busi­ness­es that determine profits via the accrual ac­count­ing method (using a profit and loss statement and balance sheet), the IRS rec­om­mends a different or­ga­ni­za­tion:

• A/R invoice folder, se­quen­tial­ly organized by document number
• Incoming invoice folder, se­quen­tial­ly organized by document number
• Account statement folder, sorted chrono­log­i­cal­ly
• Cash book folder, with sup­port­ing cash documents sorted chrono­log­i­cal­ly

Calculate profit: Cash method or accrual method?

How you calculate your profit de­ter­mines the amount of income tax you’ll pay. There are two options for cal­cu­lat­ing profit:

• Accrual Ac­count­ing Method: Uses a profit and loss statement and a balance sheet.
• Cash Ac­count­ing Method: Expenses are only rec­og­nized when the money is actually paid out.

Self-employed in­di­vid­u­als can usually use the cash method, which is simpler, while larger busi­ness­es may be required to use the accrual method.

A simple profit margin report is suf­fi­cient for self-employed in­di­vid­u­als. This simply refers to the amount of revenue from sales minus the costs of running your business. This can be cal­cu­lat­ed by sub­tract­ing your business outgoings from your business earnings.

What Can I Deduct?

Self-employed in­di­vid­u­als can deduct a variety of business expenses from their taxable income, thus lowering the overall amount of income tax they need to pay. Some common de­ductible expenses include:

• Office supplies
• Rent for business premises
• Training and ed­u­ca­tion­al costs (if relevant)
• Wages paid to employees
• Car expenses and other fixed assets subject to de­pre­ci­a­tion
• Re­tire­ment plan con­tri­bu­tions (e.g., IRA)
• En­ter­tain­ment costs (subject to limits)
• Travel expenses

File your self-em­ploy­ment tax return

Self-employed in­di­vid­u­als can file their taxes elec­tron­i­cal­ly (through the IRS e-filing system), via mail, or with a reg­is­tered tax pro­fes­sion­al.

For quarterly estimated tax payments, you must submit Form 1040-ES to pay your self-em­ploy­ment tax, Social Security, and Medicare taxes.

When filing your annual tax return, you will likely need to fill out the following forms:

• Schedule C (Profit or Loss from Business) or Schedule C-EZ (Net Profit from Business) to report profits and losses as a sole pro­pri­etor.
• Schedule SE (Form 1040) to file self-em­ploy­ment tax.

File deadlines and ex­ten­sions

The IRS rec­om­mends filing your tax return by April 15 each year. However, if you are short on time, you can file for a 6-month extension using Form 4868. This extension only applies to the filing deadline, not to payments due.

Lodge an appeal, if required

Once you submit your tax return, the IRS usually processes elec­tron­i­cal­ly filed forms within 21 days, while paper returns can take 6-8 weeks. After receiving your tax bill or refund, it’s good practice to have a tax pro­fes­sion­al review the as­sess­ment for errors. You have 30 days from the de­ter­mi­na­tion date to file an appeal in writing. The appeal should be sent to the IRS address on the letter, not directly to the Office of Appeals.
