June 15 is approaching fast. If you are a freelancer, contractor, or small business owner who pays quarterly estimated taxes, missing this deadline is not just inconvenient—it can cost you real money in IRS penalties and interest.
What Happens If You Miss the June 15 Deadline?
The IRS does not take missed payments lightly. When you skip or underpay your Q2 estimated tax payment, two things happen automatically:
- Late Payment Penalty: The IRS charges 0.5% of the unpaid tax for each month (or part of a month) the payment is late, up to 25% of the unpaid amount.
- Interest: Interest compounds daily on both the unpaid tax and the penalty. The current interest rate is 8% annually (as of Q2 2026).
For example, if you owe $3,000 in estimated taxes and miss the deadline by one month, you are looking at roughly $15 in penalties plus interest. It adds up—and more importantly, it is completely avoidable.
How to Calculate What You Owe
Before you can pay, you need to know the amount. Here is a simple formula:
Q2 Estimated Tax = (Your Annual Income × Tax Rate) ÷ 4
But there is a safer approach: Use the safe harbor rule. If you pay at least 100% of last years tax liability (or 110% if your adjusted gross income exceeded $150,000), you will not face penalties even if you underpay.
For most self-employed people:
- Calculate your net self-employment income for the year to date
- Multiply by your estimated effective tax rate (typically 25-35% including self-employment tax)
- Subtract any W-2 withholding and previous quarterly payments
- Pay the remainder by June 15
Step-by-Step: What to Do If You Missed the Deadline
Life happens. If June 15 passed and you did not pay, here is exactly what to do:
Step 1: Pay Immediately
Do not wait. The longer you delay, the more penalties accrue. Pay through:
- IRS Direct Pay: Free, immediate payment from your bank account at irs.gov/payments
- EFTPS: The Electronic Federal Tax Payment System (requires enrollment)
- Credit/Debit Card: Through IRS-approved payment processors (fees apply)
Step 2: File Form 1040-ES
Even if you have already filed for the year, you need to submit the estimated tax payment voucher with your Q2 payment. Download Form 1040-ES from the IRS website.
Step 3: Request a Penalty Abatement (If Applicable)
If this is your first time missing a payment and you have a clean compliance history, you may qualify for First-Time Penalty Abatement. Call the IRS at 1-800-829-1040 and request it—you will need to be current on all filings and have paid (or arranged to pay) the owed tax.
