Freelancing creates tax complexity that traditional employment doesn't. No employer withholds anything, you pay both halves of Social Security and Medicare yourself, and the IRS expects payments four times per year instead of once. Miss these details and April brings an expensive surprise, often with penalties on top.
Set aside 25-30% of every freelance payment into a dedicated tax savings account. This covers federal income tax (at most brackets) and the 15.3% SE tax. If your state has income tax, add another 3-8% depending on your state. If you end up over-saving, you get a refund. Under-saving means scrambling in April.
Why a separate account: money sitting in your checking account gets spent. A high-yield savings account labeled "taxes" is psychologically off-limits in a way that a checking account balance isn't.
The IRS requires quarterly estimated payments if you expect to owe $1,000 or more in taxes for the year. The 2026 due dates are April 15, June 16, September 15, and January 15, 2027.
Pay via IRS Direct Pay at irs.gov (free, no account required) or EFTPS. Keep a record of every payment made. You'll reconcile them on your April return.
To calculate each payment: take your net freelance income for the quarter, multiply by your combined tax rate (25-30% is a conservative estimate), and pay that amount. Alternatively, pay 25% of last year's total tax bill (the "safe harbor" method) — this protects you from underpayment penalties even if you earn significantly more this year.
Freelancers can deduct ordinary and necessary business expenses. These reduce your taxable net profit, which reduces both income tax and SE tax. High-value deductions:
| Deduction | Details |
|---|---|
| Home office | Dedicated space used exclusively for work. Either $5/sq ft (simplified) or actual expenses prorated by square footage. |
| Equipment | Laptop, monitor, camera, microphone. Deduct in the year purchased (Section 179) or depreciate. |
| Software and subscriptions | Adobe, Notion, Slack, project management tools used for work. |
| Internet bill | Pro-rated percentage of home internet used for business. 50-80% is common for home-based freelancers. |
| Health insurance premiums | Self-employed people can deduct 100% of health insurance premiums paid. Major deduction for those without employer coverage. |
| Retirement contributions | Solo 401k or SEP-IRA contributions reduce taxable income significantly. A SEP-IRA allows up to 25% of net self-employment income. |
| Professional development | Courses, books, certifications directly related to your field. |
You can deduct half of your self-employment tax from your gross income on Form 1040 (not just Schedule C). This partially offsets the sting of paying both employer and employee halves. It's automatic when you file Schedule SE, but knowing it exists helps with the psychological math of comparing freelance vs employed income.
The year your freelance income exceeds $30,000, the cost of a CPA (typically $300-$800 for a self-employment return) is almost always worth it. They'll catch deductions you missed, optimize your retirement account contributions to minimize SE tax, and advise on whether to elect S-corp status (beneficial for some freelancers earning above $60,000). DIY filing with software like TurboTax Self-Employed works fine below that threshold.
