How to Pay Estimated Taxes Online in 2025 — Step-by-Step Guide

The Two Ways to Pay Estimated Taxes Online

The IRS offers two main online payment systems: IRS Direct Pay and EFTPS (Electronic Federal Tax Payment System). Both are free and both work well. The difference is setup time and flexibility. Direct Pay requires no account — you pay in minutes with just your bank account and Social Security Number. EFTPS requires registration upfront but offers more control for regular payers.

For most freelancers, especially those just starting with estimated taxes, IRS Direct Pay is the right choice. It's simpler, faster, and has no learning curve.

Paying with IRS Direct Pay — Step by Step

Step 1: Go to irs.gov/payments/direct-pay in your browser. There is no app — only the website. It works fine on mobile.

Step 2: Click "Make a Payment." On the next screen, select your reason for payment: choose Estimated Tax from the dropdown. Under "Apply Payment To," select 1040ES. For Tax Period, select 2025.

Step 3: Verify your identity. Enter your name exactly as it appears on your tax return, your Social Security Number, your date of birth, and your filing status. The IRS uses this to match your payment to the right account — accuracy matters here.

Step 4: The system will ask you to confirm a prior-year tax return amount as a secondary verification (usually your 2023 or 2024 AGI). Have a copy of your prior return handy.

Step 5: Enter your bank account routing number and account number. Select checking or savings. Enter the payment amount and choose a payment date (today or a future date up to 30 days out).

Step 6: Review the confirmation screen and submit. You'll receive a confirmation number — screenshot or write it down. Payment typically posts within 1–2 business days.

Setting Up EFTPS for Recurring Payments

EFTPS (Electronic Federal Tax Payment System) at eftps.gov is the IRS's full-featured payment portal. Registration is free but takes 7–10 business days because the IRS mails your PIN by postal mail. If your first quarterly payment is coming up in the next week, use Direct Pay instead and set up EFTPS for future quarters.

To register: go to eftps.gov, click "Enroll," and enter your SSN or EIN, bank account information, and contact details. The IRS mails your 4-digit PIN to your address on file. Once received, return to eftps.gov to set your internet password and complete activation.

EFTPS advantages over Direct Pay: you can schedule payments up to 365 days in advance, view your full payment history, and receive email confirmation. If you want to schedule all four quarterly payments at the start of the year, EFTPS is the right tool.

How Much to Pay Each Quarter

This is where most freelancers get stuck. The IRS doesn't tell you what to pay — you calculate it yourself. The general rule: pay 25% of your estimated annual tax each quarter. A simpler and safer approach is the safe harbor rule: divide your total prior year tax bill by four and pay that amount each quarter. Even if your income rises significantly, safe harbor payments protect you from underpayment penalties.

Use our free Quarterly Tax Scheduler to enter your estimated income and get the exact amount for each quarter in seconds. You can also use the IRS Form 1040-ES worksheet, though it's more complex than necessary for most freelancers.

Common Mistakes to Avoid

The most common error is selecting the wrong tax period — always confirm you're paying toward 2025, not a prior year. The second most common mistake is missing the deadline by a day or two. IRS Direct Pay payments initiated by 8pm ET on the due date count as on-time. Schedule a payment a few days early to avoid any bank processing issues.

Don't wait until you have exact numbers. A reasonable estimate paid on time is better than a perfect calculation paid late. You reconcile everything on your annual return — overpayments become credits or refunds, and any remaining balance is paid by April 15 with no penalty as long as your quarterly payments met the safe harbor threshold.

Confirming Your Payment Was Applied Correctly

After paying, you can verify the payment posted by creating or logging into your IRS Online Account at irs.gov/account. Under "Tax Records," you can view all payments applied to your account and confirm they're attributed to the correct year and form. Check this annually before filing your return — it's the best way to catch errors before they become problems.
