7 days until June 15. If you haven’t started your Q2 estimated taxes, here’s exactly what to do.
Quarterly estimated taxes are a fact of life for freelancers, contractors, and small business owners. The June 15 deadline for Q2 payments is approaching fast—and missing it means penalties, interest, and a bigger headache come tax season.
Whether you’re a seasoned self-employed professional or filing estimated taxes for the first time, this checklist will help you stay compliant and avoid unnecessary fees.
What Are Quarterly Estimated Taxes?
If you earn income that isn’t subject to withholding—freelance income, contractor payments, rental income, or business profits—the IRS expects you to pay taxes throughout the year. Instead of one big payment in April, you make four quarterly payments:
- Q1 (January 1 – March 31): Due April 15
- Q2 (April 1 – May 31): Due June 15
- Q3 (June 1 – August 31): Due September 15
- Q4 (September 1 – December 31): Due January 15 of the following year
The June 15 deadline covers income earned in April and May. If you miss it, the IRS charges a failure-to-pay penalty of 0.5% of the unpaid tax per month, up to 25%, plus interest that compounds daily.
Your 7-Day Q2 Tax Checklist
Day 1: Calculate Your Q2 Income
Tally all income earned April 1 through May 31. Include:
- Freelance payments received
- Contractor income (1099-NEC, 1099-K)
- Rental income
- Business profits
- Investment income (dividends, interest)
If your income varies month to month, use the IRS Form 1040-ES worksheet to estimate your annual tax liability and calculate the quarterly portion.
Day 2: Track Every Deduction
Before calculating your payment, make sure you’re not leaving money on the table. Common Q2 deductions include:
- Home office expenses: A portion of rent, utilities, and internet
- Business supplies: Software subscriptions, equipment, office supplies
- Travel and meals: Client meetings, business trips (meals are 50% deductible)
- Health insurance premiums: Self-employed health insurance deduction
- Retirement contributions: SEP-IRA, Solo 401(k), SIMPLE IRA

Day 3: Estimate Your Tax Payment
Use one of two methods:
Method 1: Safe Harbor (Easiest)
If you pay 100% of last year’s tax liability (110% if your AGI was over $150,000), you avoid underpayment penalties even if your income is higher. Check your 2025 tax return for the total tax line, divide by four, and pay that amount.
Method 2: Annualized Income (Most Accurate)
If your income fluctuates or you had a slow Q1, use IRS Form 2210 to calculate your payment based on actual income earned in Q2. This can lower your payment if you’ve had a down quarter.
Day 4: Choose Your Payment Method
The IRS offers multiple ways to pay:
- IRS Direct Pay: Free, secure bank transfer at IRS.gov/DirectPay. Funds typically withdraw within 24 hours.
- Electronic Federal Tax Payment System (EFTPS): Free, but requires enrollment (takes 5-7 days to activate). Schedule payments in advance.
- IRS Online Account: Pay directly from your IRS account, view payment history, and set up payment plans.
- Credit or debit card: Processors charge fees (around 2% for debit, 2-4% for credit). Useful if you need to pay by card for rewards or cash flow reasons.
- Check or money order: Mail with Form 1040-ES payment voucher. Allow 7-10 days for delivery—don’t risk it this close to the deadline.
Day 5: File Form 1040-ES
If paying by check, include Form 1040-ES with your payment voucher. Electronic payments through IRS Direct Pay or EFTPS automatically associate with your SSN—no form required.
Download Form 1040-ES from the IRS website.
Day 6: Double-Check Everything
Before hitting submit:
- Verify your Social Security Number (or EIN for business income)
- Confirm the correct tax year (2026 for Q2 2026 payment)
- Check the payment amount matches your calculations
- Screenshot or save the confirmation page
Keep a record of your payment confirmation, date, and amount for your tax files. BudgetX users can attach the payment receipt to a custom expense category for easy retrieval.
Day 7: Submit Your Payment
If you’ve followed this checklist, you’re ready. Submit your payment by June 15 to avoid penalties. If the 15th falls on a weekend or holiday, the deadline is the next business day.
What Happens If You Miss the Deadline?
The IRS charges penalties even if you’re only a few days late:
- Failure-to-pay penalty: 0.5% of unpaid tax per month, up to 25%
- Interest: Compounds daily on unpaid tax and penalties (current rate ~8% annually)
- Underpayment penalty: If you paid less than 90% of your total tax liability, you may owe an additional penalty
For a $5,000 quarterly payment that’s 30 days late, you could owe around $50 in penalties plus interest—money better spent on your business.
