2025-2026 Quarterly Tax Due Dates
Who Needs to Pay Quarterly?
You need to make quarterly estimated tax payments if:
- You expect to owe $1,000 or more in federal taxes for the year
- Your withholding and credits will be less than the smaller of: 90% of this year's tax or 100% of last year's tax
- You have self-employment income (1099, freelance, contract work, side business)
If ALL your income comes from a W-2 job where taxes are withheld, you probably don't need to pay quarterly. But if you freelance on the side and that income pushes your total tax bill above the threshold, you do.
How to Calculate Your Quarterly Payment
The simple version:
2. Subtract business expenses
3. Calculate self-employment tax (15.3% of 92.35% of net income)
4. Calculate income tax on remaining taxable income
5. Add SE tax + income tax = total estimated tax
6. Divide by 4 = quarterly payment amount
The Safe Harbor Rule
If you're not sure how much you'll earn this year, the safe harbor rule protects you from underpayment penalties. Pay at least 100% of last year's total tax bill divided by 4, and you won't be penalized even if you owe more when you file. (If your AGI was over $150,000, the threshold is 110%.)
How to Actually Pay
Option 1: IRS Direct Pay (Free, Recommended)
Go to irs.gov/directpay. Select "Estimated Tax" as the reason, enter your info, and pay directly from your bank account. No fees. Takes 5 minutes. You'll get a confirmation number immediately.
Option 2: EFTPS (Electronic Federal Tax Payment System)
Set up an account at eftps.gov. Takes 5-7 business days to get your PIN by mail. Once set up, you can schedule payments in advance and set up recurring payments.
Option 3: IRS2Go App
The IRS mobile app lets you make payments from your phone. Available on iOS and Android.
Option 4: Credit/Debit Card
You can pay by card through authorized processors, but they charge a fee (1.87-1.98% for credit cards, ~$2.50 for debit). Only use this if you need the credit card rewards or cash flow flexibility.
Option 5: Check by Mail
Fill out Form 1040-ES voucher, write a check to "United States Treasury," and mail it to the IRS address for your state. Slowest option — not recommended.
What Happens If You Don't Pay (or Pay Late)?
The IRS charges an underpayment penalty on the amount you should have paid but didn't. The penalty rate is the federal short-term rate plus 3 percentage points, calculated quarterly. As of early 2026, this is approximately 7-8% annualized.
The penalty is calculated on each quarter individually. So if you paid Q1 and Q2 but missed Q3, you only get penalized on Q3.
The penalty is NOT:
- A flat fee (it's a percentage)
- Criminal (it's just interest, not fraud)
- Avoidable by filing an extension (extensions extend your filing deadline, not your payment deadline)
Common Mistakes Freelancers Make
- Not paying at all. Many first-time freelancers don't realize they need to pay quarterly until they get hit with a surprise penalty at tax time.
- Forgetting self-employment tax. Your quarterly payment needs to cover both income tax AND the 15.3% self-employment tax. Many people only estimate income tax and end up short.
- Using gross income instead of net. You estimate taxes on NET income (after business expenses), not gross. Deduct your expenses first.
- Not adjusting mid-year. If your income changes significantly, adjust your Q3 and Q4 payments. You're not locked into the same amount every quarter.
- Confusing filing extensions with payment extensions. Filing an extension (Form 4868) gives you until October to FILE, but your tax PAYMENT is still due April 15.
