Freelancing and independent contracting come with the freedom of being your boss, but they also bring new responsibilities, especially when it comes to paying taxes. Unlike traditional employees who have taxes withheld automatically from their paychecks, freelancers and contractors must calculate, report, and pay their taxes themselves, often before tax season even begins.
This is where estimated taxes come in. In this comprehensive guide, we’ll help you understand how estimated taxes work, how to calculate them, when to pay, and how to stay compliant with the IRS year-round.
What Are Estimated Taxes?
Estimated taxes are quarterly payments made to the IRS (and often your state) on income that isn’t subject to withholding. This includes:
Freelance and contract work
Side hustles or self-employment income
Rental income, dividends, and interest
Capital gains
If you expect to owe at least $1,000 in federal taxes for the year, the IRS requires you to make quarterly estimated tax payments.
Who Needs to Pay Estimated Taxes?
Estimated tax payments apply to:
Freelancers
Independent contractors
Self-employed professionals
Gig economy workers
Small business owners
Examples: Graphic designers, writers, Uber drivers, Etsy sellers, photographers, consultants, and anyone earning 1099 income should be paying estimated taxes.
Why Estimated Taxes Matter
Paying estimated taxes isn’t optional—the IRS requires it. Failing to pay can lead to:
Penalties for underpayment
Interest charges
Unexpected tax bills at year-end
Making quarterly payments helps spread your tax obligation throughout the year, preventing a large, stressful bill in April.
When Are Estimated Taxes Due?
The IRS requires payments on a quarterly schedule, even though the quarters are not evenly spaced:
| Period Income Earned | Payment Due Date |
|---|---|
| January 1 – March 31 | April 15 |
| April 1 – May 31 | June 15 |
| June 1 – August 31 | September 15 |
| September 1 – December 31 | January 15 (following year) |
Note: If the due date falls on a weekend or holiday, the deadline is the next business day.
How to Calculate Estimated Taxes
The goal is to estimate your total annual tax liability and divide it into four payments.
Step 1: Estimate Your Annual Income
Project your income for the year based on past months or expected gigs.
Step 2: Subtract Deductions and Credits
Consider:
Standard deduction or itemized deductions
Self-employed health insurance
Retirement contributions (e.g., SEP IRA or Solo 401(k))
Business expenses (software, supplies, mileage, home office)
Step 3: Calculate Your Tax Liability
Use the IRS tax brackets to determine how much federal tax you owe.
Don’t forget:
Self-employment tax: 15.3% for Social Security and Medicare (on 92.35% of net income)
Income tax: Based on your total taxable income
Step 4: Divide by Four
Split the total tax amount into four equal quarterly payments.

Self-Employment Tax: What Freelancers Need to Know
Freelancers and contractors must pay both the employer and employee portions of Social Security and Medicare taxes—this is known as self-employment tax.
Rate: 15.3% (12.4% Social Security + 2.9% Medicare)
Applies to net earnings over $400
Calculated on 92.35% of your net income
Example:
If your freelance net income is $50,000:
92.35% of $50,000 = $46,175
Self-employment tax = $7,060
Tips to Simplify Estimated Tax Payments
✅ Open a Separate Tax Savings Account
Transfer a portion (25–30%) of every payment you receive into this account to cover future tax bills.
✅ Use Accounting Software
Platforms like QuickBooks, Wave, and FreshBooks help automate calculations, track expenses, and generate reports.
✅ Pay Electronically
Use the IRS Direct Pay tool or EFTPS (Electronic Federal Tax Payment System) for fast and trackable payments.
✅ Keep Meticulous Records
Save receipts, track mileage, and maintain digital folders for income and expense categories.
Avoiding IRS Penalties
To avoid underpayment penalties, the IRS requires that you pay at least:
90% of your current year’s total tax liability, or
100% of the previous year’s tax liability (110% if your income exceeds $150,000)
If you don’t meet one of these safe harbor rules, you could owe penalties, even if you paid your full taxes later when filing.
State Estimated Taxes May Apply Too
Most states that have an income tax also require quarterly estimated payments. Each state has its own rules, forms, and due dates.
Examples:
California: Similar 4-installment structure
New York: Requires payments if expected to owe $300+
Texas, Florida: No state income tax (federal only)
Be sure to check with your state tax agency or consult a local CPA.
Common Mistakes to Avoid
❌ Forgetting to pay – Set calendar reminders for due dates
❌ Not accounting for self-employment tax – It adds up fast
❌ Ignoring income spikes – Adjust your next payment if your income rises
❌ Missing deductions – Every legitimate write-off reduces your tax bill
❌ Underestimating income – Leads to year-end surprises and penalties
When to Work With a Tax Professional
If your freelance or contract work is growing, or your income varies significantly, a tax professional can help you:
Set up estimated tax schedules
Maximize deductions
Minimize penalties
Plan for retirement with tax-advantaged accounts
Stay compliant with federal and state tax laws
