Tax for Self-Employed Individuals: A Comprehensive Guide for 2025

What is the Tax for Self-Employed Individuals?

If you work for yourself, whether as a freelancer, independent contractor, or small business owner, you’re responsible for handling your own taxes. Unlike traditional employees, whose employers withhold taxes from their paychecks, self-employed individuals must calculate, file, and pay taxes themselves. This includes not only income tax but also self-employment tax, which covers Social Security and Medicare contributions.

In 2025, tax regulations and rates for self-employed individuals remain a critical consideration. Understanding how self-employment taxes work, what deductions are available, and how to stay compliant with estimated tax payments can help you manage your finances effectively and avoid unexpected penalties.

What Taxes Do Self-Employed Individuals Pay?

When you’re self-employed, you’re responsible for two main types of taxes: income tax and self-employment tax.

Income tax is based on your net profit, which is the amount you earn after subtracting business expenses. You’ll pay federal income tax and, depending on where you live, state or local income tax.

Self-employment tax covers Social Security and Medicare contributions. Traditional employees split these taxes with their employer, but as a self-employed individual, you’re on the hook for both portions. The self-employment tax rate is 15.3% in 2025, which consists of 12.4% for Social Security and 2.9% for Medicare.

For higher earners, there is an additional 0.9% Medicare surtax on income exceeding $200,000 for single filers or $250,000 for married couples filing jointly. This means that if your net self-employment income exceeds these thresholds, your Medicare tax rate increases slightly on the excess amount.

How to Calculate the Tax for the Self-Employed

Calculating your self-employment tax starts with determining your net earnings. This is your total income from self-employment minus deductible business expenses.

For example, if you earned $80,000 from self-employment in 2025 and had $20,000 in business expenses, your net income is $60,000. You’ll pay self-employment tax on this $60,000, not on the full $80,000.

To calculate the tax, you first multiply your net earnings by 92.35% (this accounts for the employer portion of Social Security and Medicare taxes being deductible). Then, you apply the 15.3% self-employment tax rate.

For $60,000 in net income, the calculation would look like this:
$60,000 × 92.35% = $55,410
$55,410 × 15.3% = $8,478.63

This $8,478.63 represents your self-employment tax. You’ll report this on your tax return using Schedule SE (Form 1040) and can deduct half of the self-employment tax (in this case, $4,239.32) from your taxable income.

Estimated Tax Payments and Deadlines

One of the biggest challenges for self-employed individuals is making estimated tax payments throughout the year. Because taxes are not automatically withheld from your income, the IRS requires you to make quarterly estimated payments if you expect to owe $1,000 or more in taxes for the year.

For 2025, the quarterly estimated tax payment deadlines are:

• April 15, 2025 (for income earned January 1 – March 31)
• June 16, 2025 (for income earned April 1 – May 31)
• September 15, 2025 (for income earned June 1 – August 31)
• January 15, 2026 (for income earned September 1 – December 31)

Failing to make estimated payments can lead to underpayment penalties. To calculate your estimated payments, you’ll need to project your income and tax liability for the year. The IRS provides Form 1040-ES to help you estimate your payments.

Deductions and Write-Offs for the Self-Employed

One of the biggest advantages of being self-employed is the ability to deduct legitimate business expenses, which can significantly reduce your taxable income.

Common deductions include home office expenses, which apply if you use part of your home exclusively for business. You can either deduct a percentage of your home-related expenses (like rent, utilities, and internet) based on the size of your office relative to your home, or use the simplified deduction method, which allows you to deduct $5 per square foot of office space, up to 300 square feet.

Other deductions include business-related travel and meal expenses. Travel expenses such as airfare, hotels, and car rentals are fully deductible if they’re directly related to your business. Meals purchased during business-related travel or client meetings are 50% deductible.

Self-employed individuals can also deduct health insurance premiums for themselves, their spouse, and their dependents. This is especially valuable if you don’t have access to employer-sponsored health coverage.

In addition, you can deduct contributions to retirement plans, such as a Simplified Employee Pension (SEP) IRA or a solo 401(k). Contributions to these plans reduce your taxable income while helping you save for retirement.

The Self-Employed Tax: Record-Keeping and Documentation

Bien record-keeping is essential for self-employed individuals to accurately report income, claim deductions, and prepare for potential audits. It’s important to maintain detailed records of all income earned and expenses paid.

Keep copies of invoices, receipts, bank statements, and credit card records. Using accounting software or hiring a bookkeeper can help streamline record-keeping. When claiming deductions, be sure to keep documentation that clearly shows the business purpose of each expense.

For mileage deductions, use a mileage tracking app or keep a logbook documenting the date, purpose, and distance of each business-related trip.

State and Local Taxes for the Self-Employed

In addition to federal taxes, self-employed individuals are also responsible for state and local taxes, which vary by location.

Most states impose an income tax, and you’ll need to file a state tax return in addition to your federal one. Some states, such as California and New York, also have self-employment tax requirements or franchise taxes for small businesses.

If you operate in a state without income tax, such as Texas, Florida, or Nevada, you won’t have to worry about state income taxes, but you may still be subject to local business taxes or licensing fees.

Special Considerations for 2025

Tax regulations for the self-employed are always evolving. In 2025, new IRS compliance measures aim to increase scrutiny on gig economy workers and freelancers who receive income through third-party platforms. Payment processors, such as PayPal, Venmo, and Square, are required to issue Form 1099-K for payments over $600, making it easier for the IRS to track small business and freelance income.

There are also ongoing discussions around tax reform that could impact self-employment tax deductions, making it essential for independent workers to stay informed on any legislative changes.

The Final Word on the Tax for the Self-Employed…

Paying taxes as a self-employed individual may seem daunting, but with careful planning and organization, it can be managed effectively. Knowing how to calculate self-employment tax, making estimated payments on time, and taking advantage of deductions can help you reduce your tax liability and stay compliant.

By keeping accurate records, staying on top of deadlines, and consulting with a tax professional when needed, you can avoid costly penalties and maximize your deductions. Whether you’re a full-time freelancer or run a side hustle, understanding self-employment taxes is essential for keeping more of your hard-earned income in 2025 and beyond.

Tax for Self-Employed Individuals: FAQ

1. How do I know if I’m considered self-employed for tax purposes?
You’re considered self-employed if you operate your own business or work as an independent contractor, freelancer, or gig worker. This also applies to sole proprietors, members of a partnership, and individuals earning income through platforms like Uber, Etsy, or Upwork. Even if you have a full-time job and earn side income from a business or freelance work, the IRS considers you self-employed for that extra income. You’ll need to file a Schedule C with your Form 1040 to report business income and expenses, and you’ll also need to pay self-employment tax on your net earnings.

2. What expenses can I deduct as a self-employed individual?
As a self-employed individual, you can deduct a wide range of business-related expenses that help reduce your taxable income. Common deductible expenses include home office costs, such as a portion of your rent, utilities, and internet if you work from home. You can also deduct business supplies, equipment, and software necessary for your work.

Travel expenses, including airfare, lodging, and meals, are deductible if they are directly related to your business. Vehicle expenses, such as mileage driven for business purposes, can be written off either using the standard mileage rate or actual expenses. Professional services like accounting, legal fees, and marketing costs are also deductible. Additionally, you can deduct retirement plan contributions, health insurance premiums, and even educational expenses if they improve your skills for your business.

3. Do I need to pay taxes on income received through payment platforms like PayPal or Venmo?
Yes, income earned through payment platforms such as PayPal, Venmo, and Cash App is taxable, even if it wasn’t reported to you on a Form 1099. Starting in 2025, third-party payment platforms are required to issue Form 1099-K for business payments totaling $600 or more during the year. Even if you don’t receive a 1099-K, you are still legally required to report all self-employment income on your tax return.

Failing to report income, even from smaller transactions, can trigger penalties and interest if discovered by the IRS. To stay compliant, it’s best to keep thorough records of all income, including payments received through digital platforms.

4. What happens if I underpay my estimated taxes?
If you underpay your estimated taxes, you may be subject to penalties and interest on the unpaid amount. The IRS expects self-employed individuals to make regular, timely payments throughout the year. If you pay too little or miss a deadline, the IRS may charge you an underpayment penalty, even if you pay the full amount by the end of the year.

To avoid penalties, it’s a good idea to base your estimated payments on at least 100% of your previous year’s total tax liability or 110% if your adjusted gross income was over $150,000. This safe harbor rule helps you avoid underpayment penalties, even if your income ends up being higher than anticipated.

5. Can I hire my spouse or children and reduce my tax burden?
Yes, hiring your spouse or children can be a legitimate way to reduce your tax burden, but it must be handled properly. When you hire a family member, their wages become a deductible business expense, which lowers your taxable income. However, the family member must perform actual work and be paid a reasonable wage. If you hire your children under the age of 18, you can avoid paying Social Security and Medicare taxes on their wages if you operate a sole proprietorship or partnership with only you and your spouse as partners.

This can result in significant tax savings. Additionally, wages paid to your children can be used to fund their Roth IRA, which is a tax-efficient way to save for their future. However, it’s important to keep accurate records and issue a W-2 to the family member to remain compliant with tax laws.
