You just filed your 2025 return in April. You barely had time to exhale. And now the IRS wants another payment in less than two months.
That's the reality of quarterly estimated taxes: the gap between Q1 (April 15) and Q2 (June 16) is the shortest of the year. Only 62 days. If you're not prepared, it sneaks up fast.
This guide walks you through everything you need for your Q2 payment: who owes, how to calculate the right amount, how to actually submit the payment, and what happens if you miss the deadline. No fluff, no theory — just the steps.

The Q2 deadline: June 16, 2026
The second quarterly estimated tax payment for 2026 is due Monday, June 16, 2026. It covers income earned from April 1 through May 31 — only two months, unlike most other quarters which cover three.
Why June 16 instead of June 15? Because June 15 falls on a Sunday in 2026. When a tax deadline lands on a weekend or federal holiday, the IRS shifts it to the next business day.
Here are all four quarterly due dates for 2026 at a glance:
Notice the uneven structure. Q2 is the only two-month quarter. Q3 and Q4 each cover three and four months, respectively. This means the Q2 deadline arrives just two months after Q1 — which is why it catches so many self-employed workers off guard.
Who needs to pay Q2 estimated taxes?
You're required to make quarterly estimated tax payments if you expect to owe $1,000 or more in federal tax for 2026, after subtracting any withholding and refundable credits.
This applies to you if you are:
- A freelancer or independent contractor receiving 1099-NEC income
- A sole proprietor or single-member LLC with business profits
- A gig worker (DoorDash, Uber, Instacart, Etsy, Amazon FBA, etc.)
- Someone with significant investment income — dividends, capital gains, rental income
- A W-2 employee with a profitable side business where your paycheck withholding doesn't cover the extra tax
The threshold hasn't changed in years. If your net self-employment income will exceed roughly $5,000–$6,000 for the year, you almost certainly owe more than $1,000 in combined self-employment and income tax. That means quarterly payments are required.
If you're not sure whether you need to pay, the simplest test is this: did you owe money when you filed your 2025 return? If yes, you very likely need to make estimated payments for 2026.
How to calculate your Q2 payment
There are two IRS-approved methods. You only need to satisfy one of them to avoid the underpayment penalty.
Method 1: Prior year safe harbor
This is the simplest and safest approach for most self-employed workers. Take your total tax liability from 2025 (line 24 on your 2025 Form 1040) and divide by four. Pay that amount each quarter.
The rule is:
- If your 2025 AGI was $150,000 or less ($75,000 if married filing separately): pay at least 100% of your 2025 total tax, divided into four equal payments.
- If your 2025 AGI was over $150,000: pay at least 110% of your 2025 total tax, divided into four equal payments.
Why is this the "safe harbor"? Because even if you earn dramatically more in 2026, you'll owe zero underpayment penalties as long as your quarterly payments total at least 100% (or 110%) of last year's tax. You'll owe a balance when you file in April 2027, but there's no penalty attached to it.
Example: Your 2025 total tax was $14,000 and your AGI was under $150K. Your safe harbor quarterly payment is $14,000 / 4 = $3,500 per quarter. Pay $3,500 by June 16 for Q2. Done.
Method 2: Current year estimate
Calculate your expected tax for each quarter based on actual income earned during that period. This method requires more work but can be more accurate — especially if your income fluctuates.
For Q2 (April–May), the formula is:
- Add up your net self-employment income for April and May (revenue minus business expenses)
- Calculate self-employment tax: net income x 92.35% x 15.3%
- Estimate income tax: apply your marginal federal tax bracket to the net income (after deducting half of SE tax)
- Total Q2 tax = SE tax + income tax for those two months
Worked example: freelancer earning $6,000/month
Let's say you're a freelance web developer earning approximately $6,000 per month in net self-employment income (after business deductions). Here's how both methods work for your Q2 payment.
Method 1 (safe harbor):
Your 2025 total tax was $16,200 (on $72,000 net SE income). Your AGI was under $150K, so you need 100% of last year's tax.
Q2 payment = $16,200 / 4 = $4,050
Method 2 (current year):
April–May net income: $6,000 x 2 = $12,000
Self-employment tax: $12,000 x 92.35% x 15.3% = $1,695
Deductible half of SE tax: $848
Taxable income for the period: $12,000 - $848 = $11,152
Federal income tax (assuming 22% bracket): $11,152 x 22% = $2,453
Q2 payment: $1,695 + $2,453 = $4,148
In this case, both methods produce similar results. The safe harbor method is simpler because you already know the number from your 2025 return — no new calculations required.
Income dropping? Use the current year estimate. Overpaying based on a higher prior year ties up cash you need now.
Income steady? Either works. The safe harbor is simpler since you already have the number.
How to actually pay your Q2 estimated taxes
You have four ways to submit your payment to the IRS. All are free except credit/debit cards.
Free, instant, no account needed
Go to irs.gov/directpay. Select "Estimated Tax" as the reason for payment. Choose tax year 2026 and quarter 2. Enter your bank account and routing number. Confirm. You get an instant confirmation number. The entire process takes about five minutes.
Best for recurring scheduled payments
The Electronic Federal Tax Payment System (eftps.gov) lets you schedule payments in advance. You'll need to enroll first — it takes about a week to receive your PIN by mail. Once enrolled, you can schedule all four quarterly payments at the start of the year and never think about deadlines again. If you haven't enrolled yet, start now so you're set up for Q3.
Convenient, but there's a fee
Pay through an IRS-approved processor (payUSAtax.com, Pay1040.com, or ACI Payments). Credit cards incur a 1.85%–1.98% convenience fee. Debit cards have a flat fee of $2.20–$2.50. This only makes sense if you're earning credit card rewards that exceed the fee — otherwise, use Direct Pay.
Old school, but it works
Print the 1040-ES payment voucher for Q2 2026, write a check payable to "United States Treasury," and mail both to the IRS address listed on the voucher. Allow extra time for mail processing. Most tax software generates these vouchers automatically when you file your prior year return.
| Method | Fee | Speed | Best for |
|---|---|---|---|
| IRS Direct Pay | Free | 1–2 business days | Most people |
| EFTPS | Free | Scheduled | Recurring payments |
| Credit/debit card | 1.85–1.98% | Same day | Rewards maximizers |
| Form 1040-ES by mail | Free + postage | Mail time | Paper filers |
Don't forget state estimated taxes
Federal estimated taxes are only half the story. If you live in a state with an income tax, you almost certainly owe a state quarterly payment too — and most states follow the same due dates as the IRS.
That means your state Q2 payment is also likely due June 16, 2026. You'll need to pay it separately through your state's department of revenue website.
States with no income tax (no estimated payments needed): Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming.
Everyone else: check your state's revenue department website for the exact payment portal and confirm the due date. A few states have slightly different schedules, so don't assume it automatically matches the federal calendar.

What happens if you miss the June 16 deadline
Missing a quarterly payment triggers the IRS underpayment penalty. Here's how it works:
The penalty rate: The federal short-term interest rate plus 3 percentage points. For 2026, this is approximately 7–8% annualized.
How it's calculated: The penalty applies only to the underpaid amount, for the number of days between the missed deadline and the date you eventually pay (or the next deadline, whichever comes first).
Real numbers: If you owe $3,500 for Q2 and pay nothing by June 16, the penalty accrues at roughly $0.67–$0.77 per day. Miss it by one month (pay on July 16) and you're looking at about $20–$23 in penalties. Not devastating, but completely avoidable.
How it compounds: The penalty is calculated separately for each quarter. If you miss Q2 and then also miss Q3, you're accruing penalties on both underpayments simultaneously. By tax filing time, those small daily amounts can add up to a few hundred dollars — plus you still owe the full tax.
• You had a casualty, disaster, or other unusual circumstance and imposing the penalty would be inequitable
• You retired (after reaching age 62) or became disabled during 2026 or 2025, and the underpayment was due to reasonable cause
• Your total tax owed (after withholding and credits) is less than $1,000 when you file
Mid-year tax check: should you adjust your Q2 payment?
Your Q2 payment is a good time to reassess your tax situation for the year. Ask yourself:
- Has your income changed significantly since January? If you landed a major client in March or lost a contract in April, your annual tax liability has shifted. Adjust accordingly.
- Did you have any big deductions? A large equipment purchase, a home office setup, or significant business travel in Q1 could lower your effective tax rate.
- Are you using the safe harbor method? If so, your Q2 payment stays the same regardless of income changes. That's the whole point — predictability.
If you're using the current-year method and your April–May income was materially different from Q1, adjust your Q2 payment to reflect the actual income earned. Overpaying isn't a penalty issue, but it does tie up cash. Underpaying creates a penalty risk.
The Deadline Dashboard can help you track where you stand relative to each deadline.
5 common Q2 mistakes (and how to avoid them)
1. Only paying federal, forgetting state
This is the most common mistake, especially for first-year freelancers. Federal and state are separate payments to separate agencies. If you live in a state with income tax and only pay the IRS, your state will charge its own underpayment penalty. Pay both on or before June 16.
2. Using gross income instead of net
Your estimated tax payment is based on net self-employment income — revenue minus legitimate business deductions. If you earned $8,000 in April but spent $2,000 on business expenses, your net income for the month is $6,000. Using gross income means you'll overpay, which hurts your cash flow even though you'll get it back as a refund.
3. Not adjusting for income fluctuations
If you use the current-year method, each quarterly payment should reflect actual income for that period. A freelancer who earned $15,000 in Q1 but only $8,000 in Q2 shouldn't pay the same amount for both quarters. If you're using the safe harbor method, this doesn't apply — your payment is fixed.
4. Waiting until April to deal with all of it
Some self-employed workers skip quarterly payments entirely and plan to "deal with it at tax time." This is the most expensive approach. You'll owe the full year's tax plus underpayment penalties on all four quarters. On a $16,000 annual tax liability, that could mean $300–$500 in avoidable penalties.
5. Forgetting to record the payment for your records
Save your IRS Direct Pay confirmation number, EFTPS receipt, or check copy. You'll need to enter your total estimated tax payments on your 2026 return (Form 1040, line 26). If you can't prove what you paid, reconciling with the IRS becomes a headache.
Your Q2 action checklist
Before June 16, 2026
- Review your 2025 return — pull your total tax from line 24 of Form 1040
- Choose your method — safe harbor (prior year) or current year estimate
- Calculate your Q2 federal payment — prior year tax / 4, or actual Q2 income x tax rate
- Calculate your Q2 state payment — check your state's estimated tax form or online calculator
- Pay federal via IRS Direct Pay — irs.gov/directpay, select "Estimated Tax," tax year 2026, Q2
- Pay state via your state's revenue website — separate payment, same deadline
- Save confirmation numbers — for both federal and state payments
- Set a reminder for Q3 — September 15, 2026 (covers June–August income)
- Review year-to-date income — adjust future payments if income has changed significantly
The June 16 deadline doesn't have to be stressful. If you know the amount, know the method, and submit the payment a few days early, it takes less time than making a cup of coffee. The key is not letting the short Q1-to-Q2 window catch you off guard.
