When you earn money from an employer, taxes are handled for you. The employer withholds income tax and pays half of your Social Security and Medicare taxes before you ever see the money. Your only job is filing a return in April.
When you freelance or work as an independent contractor, that changes. You receive full payment with no withholding, and you’re responsible for figuring out how much tax you owe and sending it in on time. It’s manageable, but it requires a system.
What Is Different About 1099 Income
When a client pays you as a contractor and the amount exceeds $600, they are required to send you a 1099-NEC by January 31. This form reports your earnings to you and to the IRS.
Unlike a W-2, no taxes are withheld from 1099 income. You receive every dollar, and you owe taxes on it later.
You still owe taxes on amounts under $600 even if no 1099 was sent. Self-employment income is always taxable, regardless of whether you received a form.

Self-Employment Tax: The Extra Tax You Owe
This is the part most new freelancers miss.
When you have a regular job, you and your employer each pay half of Social Security and Medicare taxes (together called FICA). The employer pays 7.65% and withholds another 7.65% from your pay. You cover half; they cover half.
When you’re self-employed, there’s no employer. You pay both halves, the full 15.3% on net self-employment income up to the Social Security wage base, with the Medicare portion applying more broadly. This is called self-employment tax, and it’s separate from income tax. Check IRS.gov for the current wage base because it changes over time.
In practice: if your net freelance income is $50,000, you owe roughly $7,065 in self-employment tax plus income tax on that same income. The self-employment tax comes before income tax brackets. It’s significant.
One partial offset: you can deduct half of your self-employment tax as an adjustment to income on your return, which reduces your taxable income slightly.
Quarterly Estimated Taxes: Why They Exist and When You Owe Them
The U.S. tax system is pay-as-you-go. When you have an employer, withholding accomplishes this automatically. When you don’t, the IRS expects you to pay taxes quarterly throughout the year rather than in one lump sum in April.
If you expect to owe more than $1,000 in federal taxes for the year from self-employment income, you’re generally required to make estimated payments. Skipping them can result in an underpayment penalty. Not enormous, but avoidable.
Quarterly due dates (approximate, confirm at IRS.gov):
- Q1 (January–March income): payment due mid-April
- Q2 (April–June income): payment due mid-June
- Q3 (July–September income): payment due mid-September
- Q4 (October–December income): payment due mid-January
How to calculate the payment: Estimate your total income for the year, subtract any deductions, apply the appropriate tax rates, add self-employment tax, and divide by four. IRS Form 1040-ES includes worksheets for this calculation.
An easier starting point: set aside 25–30% of each freelance payment in a separate savings account as you receive it. Pay that amount quarterly to the IRS. For most people with modest self-employment income, 25–30% is a reasonable buffer that covers both income tax and self-employment tax.
Pay at IRS.gov/payments. It’s free, immediate, and creates a record.
If you also have a regular W-2 job alongside freelance work, you may be able to increase your withholding at your day job to cover the self-employment income, avoiding the need for separate quarterly payments. Use IRS Form W-4 for this.
Deductible Business Expenses
One real advantage of self-employment: legitimate business expenses reduce your taxable income before tax is calculated. This is different from the standard deduction. Business expenses are subtracted from business income on Schedule C, before your income tax is calculated.
Common deductible expenses for freelancers:
Home office deduction If you use a dedicated space in your home exclusively and regularly for work, you can deduct the proportional cost. Two methods: the simplified method ($5 per square foot, up to 300 square feet) or the actual expense method (calculate the percentage of your home used for work and apply it to rent, utilities, etc.). The “exclusive use” rule is strict. A desk in a bedroom that’s also used for personal activities may not qualify.
Equipment and supplies Computers, monitors, cameras, microphones, software subscriptions, office supplies, anything used for your work. If you use equipment partly for personal use, deduct only the business-use percentage.
Professional services Accounting fees (including the cost of getting your taxes done), legal fees related to your business, professional memberships, and industry subscriptions.
Phone and internet If used for business, you can deduct the business-use portion. Keep records to support the percentage claimed.
Travel Business travel is deductible. Commuting to a regular place of work is not. Transportation for client meetings, business events, or work-related travel may be.
Marketing and business costs Website hosting, domain registration, business cards, advertising, platforms you use to find work.
Keep receipts or records for any deduction you claim. The IRS can ask you to substantiate expenses. A simple folder, spreadsheet, or dedicated credit card for business purchases makes this easier.
Schedule C: What It Is and How It Works
Schedule C is the form where sole proprietors and single-member LLCs (taxed as sole proprietors) report business income and expenses. It attaches to your regular Form 1040.
The math is simple:
- Revenue: Total business income received
- Minus expenses: All deductible business costs
- Equals net profit (or loss)
Your net profit is what you pay self-employment tax on, and what flows to your regular income tax calculation. Legitimate expenses reduce both.
If you show a net loss (expenses exceeded income), that loss can offset other income on your return. But consistently showing losses raises IRS scrutiny, particularly if the activity looks more like a hobby than a business.
Filing a Schedule C is required if your net self-employment income was $400 or more.

Retirement Accounts for the Self-Employed
Without an employer providing a 401(k), self-employed people have their own options, often more generous than traditional employer plans:
SEP-IRA (Simplified Employee Pension) Allows you to contribute up to 25% of your net self-employment income, up to an IRS-adjusted annual limit (check IRS.gov for the current year’s amount, it changes annually). Contributions are tax-deductible. Simple to set up at any major brokerage.
Solo 401(k) For self-employed people with no full-time employees other than a spouse. You act as both employer and employee, allowing contributions in both roles. Total limit is higher than a SEP-IRA in some scenarios, particularly if your income is moderate. More complex to administer.
Traditional or Roth IRA Available to anyone with earned income, including self-employment income. Contribution limits are lower than SEP-IRA or Solo 401(k), but these accounts are simple to maintain. See Traditional IRA vs Roth IRA.
These accounts reduce taxable income, which reduces both income tax and (for traditional accounts) the base for self-employment tax calculations. For a high-income freelancer, contributing to a retirement account is one of the most effective ways to reduce a tax bill.
When To Hire a Tax Professional
DIY tax filing with software works well for many self-employed people. Consider hiring a CPA or enrolled agent if:
- Your gross freelance income is significant and your expenses are complex
- You’re uncertain about which expenses qualify or how to calculate the home office deduction
- You received a notice from the IRS
- You’re also handling business taxes for an LLC taxed as an S corporation
- You simply want the time back and the professional liability of someone signing off on your return
The cost of a CPA for a self-employed return typically runs $200–$600 depending on complexity. That cost is itself deductible as a business expense.
Frequently Asked Questions
Q: Do I need to register as an LLC to deduct expenses?
No. Sole proprietors, anyone working for themselves without formal business structure, can deduct business expenses on Schedule C. You don’t need an LLC for this. LLCs have liability and other legal benefits, but they don’t add or remove tax deductions.
Q: What if I forget to make a quarterly payment?
Make it as soon as you can. The penalty for underpayment is calculated on the unpaid amount over time, so paying late is better than not paying at all. You can still pay for a missed quarter late. The IRS will calculate any penalty owed when you file.
Q: I only freelanced for part of the year. Do I still need to file Schedule C?
If your net self-employment income was $400 or more for the year, yes. The threshold is low.
Q: What records should I keep?
Income: copies of invoices, 1099 forms, bank statements showing deposits. Expenses: receipts, bank statements, credit card statements showing business purchases. For home office: floor plan and square footage. Keep records for at least three years from the filing date, as the IRS can audit that far back for most returns.
Q: Can I deduct health insurance premiums?
If you’re self-employed and not eligible for employer-sponsored coverage through a spouse, you can deduct health, dental, and vision insurance premiums for yourself and your family as an adjustment to income (not on Schedule C). This is a meaningful deduction for full-time freelancers paying for their own coverage.
