The June 15 estimated tax deadline is just weeks away. If you’re a freelancer, contractor, or small business owner, this is one deadline you can’t afford to miss. Unlike W-2 employees who have taxes withheld automatically, self-employed individuals must pay their taxes quarterly — and the IRS doesn’t send reminders.
What Are Estimated Taxes and Who Must Pay Them?
Estimated taxes are quarterly payments made to the IRS to cover income that isn’t subject to withholding. This includes:
- Freelance income — Any 1099 income from clients
- Contract work — Independent contractor payments
- Business profits — Income from sole proprietorships or partnerships
- Investment income — Dividends, interest, and capital gains
- Rental income — Profits from rental properties
You’re required to pay estimated taxes if you expect to owe $1,000 or more when you file your tax return. For most self-employed individuals, this threshold is easily exceeded.
The IRS requires these payments because the U.S. tax system operates on a “pay-as-you-go” basis. When you’re an employee, your employer withholds taxes from each paycheck. When you’re self-employed, you must make those payments yourself — four times per year.
When Are Estimated Tax Payments Due?
The quarterly estimated tax deadlines for 2026 are:
| Quarter | Coverage Period | Deadline |
|---|---|---|
| Q1 | January 1 – March 31 | April 15 |
| Q2 | April 1 – May 31 | June 15 |
| Q3 | June 1 – August 31 | September 15 |
| Q4 | September 1 – December 31 | January 15 (following year) |
Notice that Q2 covers only two months (April and May), while Q1 covers three months. This means your Q2 payment will typically be smaller than your Q1 payment — but it’s just as important to pay on time.
The Safe Harbor Rule: How to Avoid Underpayment Penalties
The IRS charges underpayment penalties if you don’t pay enough tax throughout the year. However, there’s a “safe harbor” rule that protects you from penalties if you meet one of these thresholds:
Safe Harbor Option 1: Pay at least 90% of your current year’s tax liability.
Safe Harbor Option 2: Pay at least 100% of last year’s tax liability (110% if your adjusted gross income was over $150,000).
For most freelancers, Option 2 is the safer choice because it’s based on a known number — your prior year tax return. If you earned $75,000 last year and owed $12,000 in taxes, you’d need to pay $3,000 per quarter (or $3,300 if your AGI exceeded $150,000).
Why the 110% rule? High earners often see income fluctuations year to year. The extra 10% buffer protects the IRS when your income jumps significantly.
How to Calculate Your Q2 Estimated Tax Payment
Here’s a step-by-step approach to calculating your June 15 payment:
Step 1: Estimate Your Annual Income
Project your total self-employment income for 2026. Look at:
- Your income from January through May
- Contracts and recurring client work
- Expected projects for the rest of the year
- Seasonal patterns in your business
Step 2: Calculate Self-Employment Tax
Self-employment tax covers Social Security and Medicare. For 2026, the rate is 15.3% on net earnings up to the Social Security wage base ($176,100 for 2026), plus 2.9% on earnings above that.
Step 3: Estimate Your Income Tax
Apply your tax bracket to your taxable income after deductions. Don’t forget:
- Standard deduction or itemized deductions
- Qualified business income deduction (up to 20% of qualified income)
- Retirement contributions (SEP-IRA, Solo 401k)
Step 4: Divide by Four
Total estimated tax ÷ 4 = quarterly payment. For Q2, this is your payment for April and May income.
Step 5: Pay on Time
Use IRS Direct Pay, EFTPS, or your tax software to make the payment by June 15.

7 Common Deductions Freelancers Miss
Many self-employed individuals leave money on the table by overlooking legitimate deductions. Here are the most frequently missed write-offs:
- Home office expenses — The simplified method allows $5 per square foot, up to 300 sq ft ($1,500 maximum)
- Internet and phone — Deduct the business percentage of your bills
- Software subscriptions — Tools you use for work (including BudgetX!)
- Professional development — Courses, books, and conferences
- Health insurance premiums — Self-employed health insurance deduction
- Retirement contributions — SEP-IRA or Solo 401k contributions reduce taxable income
- Bank and payment processing fees — PayPal, Stripe, and wire transfer fees
Don’t make these common deduction mistakes that trigger IRS scrutiny.
Step-by-Step Receipt Organization Workflow
Proper receipt documentation is essential for defending deductions during an audit. Follow this workflow:
1. Capture Immediately
Scan every receipt the moment you receive it. Paper receipts fade, and memory fails. These 7 receipts should never be thrown away.
2. Categorize Consistently
Use consistent categories that match your Schedule C line items:
- Advertising
- Car and truck expenses
- Contract labor
- Depreciation
- Insurance
- Legal and professional services
- Office expenses
- Rent or lease
- Supplies
- Travel and meals
- Utilities
3. Add Notes and Context
For each receipt, note the business purpose. “Lunch with client to discuss Q2 project scope” is audit-ready. “Lunch” is not.
4. Export Monthly
At the end of each month, export your organized receipts to share with your accountant or import into tax software.
5. Reconcile Quarterly
Before each estimated tax payment, reconcile your receipts against bank and credit card statements. This catches missing deductions and ensures accuracy.

What Happens If You Miss the June 15 Deadline?
If you miss the deadline, pay as soon as possible. The IRS charges interest on the unpaid amount from the due date until you pay. The current underpayment penalty rate is around 8% annually, calculated daily.
More importantly, missing one quarterly payment often leads to missing more. The debt compounds, and by tax time, you could owe thousands in penalties alone.
