You can pay the IRS directly from a bank account online for free, by credit or debit card through a third-party processor for a fee, by mailing a check or money order, or in cash at a participating retail store. Which method makes sense depends on how much you owe, how fast the payment needs to post, and whether you want a paper trail or a digital confirmation. If you can’t pay the full amount, the IRS offers short-term extensions and installment agreements rather than expecting you to skip filing.
What to Have Ready Before You Pay
Every payment has to be tied to your account, so the IRS needs your Social Security Number or Individual Taxpayer Identification Number, the tax year the payment covers, and the form number it relates to. A $2,000 payment sent without specifying whether it applies to your 2025 Form 1040 balance or your 2026 estimated taxes can end up in the wrong bucket and generate collection notices for a bill you already paid.
If you’re writing a check or money order, make it payable to U.S. Treasury. Writing “IRS” can cause the payment to be rejected in processing. Include a Form 1040-V voucher with any mailed balance-due payment; it captures your name and address as they appear on the return, the amount, and your SSN.
For online payments through Direct Pay, the system verifies your identity against information from a prior year’s return before it will accept anything, so keep a recent return within reach when you sit down to pay.
Paying Online From a Bank Account
The cheapest and fastest option is pulling funds directly from your checking or savings account. Two free services handle this.
IRS Direct Pay
Direct Pay is built for one-off payments. You pick the reason (balance due, estimated tax, extension, amended return), verify your identity, enter your routing and account numbers, and submit. The system gives you a confirmation number that acts as your receipt. Business tax payments cap at $10 million per transaction, and individual payments don’t have a published hard cap. You can modify or cancel a scheduled Direct Pay payment up to two business days before its scheduled date.
EFTPS
The Electronic Federal Tax Payment System is a free Treasury service designed for people who pay often, such as business owners, self-employed filers, and anyone making quarterly estimated payments. Enrollment isn’t instant: after you sign up online, the system mails a PIN to your registered address, and you can’t pay until it arrives. Once you’re set up, you can schedule payments up to 365 days in advance, cancel or change them up to two business days before the scheduled date, and pull 15 months of payment history. EFTPS also accepts payments by phone.
Paying by Credit or Debit Card
The IRS doesn’t take cards directly. Two authorized third-party processors do, and each charges a convenience fee that goes to the processor rather than the government.
- Pay1040 charges 1.75% for credit cards ($2.50 minimum), a flat $2.15 for personal debit cards, and 2.89% for commercial cards ($2.50 minimum).
- ACI Payments, Inc. charges 1.85% for credit cards ($2.50 minimum), a flat $2.10 for personal debit cards, and 2.95% for corporate cards ($2.50 minimum).
On a $5,000 credit card payment, the fee runs roughly $87 to $93. That math gets painful fast on a large balance. Debit cards are much cheaper because the fee is flat regardless of the payment amount. If you’re weighing a card payment for the rewards, compare the fee against what you’d actually earn before you commit.
Mailing a Check or Money Order
Send your check or money order with a completed Form 1040-V. Don’t staple, clip, or otherwise attach the check to the voucher or the return. Loose is correct. The IRS runs automated scanners that jam on stapled documents, which pushes your payment further back in the queue.
The mailing address depends on where you live. The IRS routes payments to different regional processing centers, and the Form 1040-V instructions list the correct address for your state. As of the most recent instructions, taxpayers in ten southeastern states mail to Charlotte, NC, while most other states mail to Louisville, KY. Filers with foreign addresses use a separate Charlotte address.
The Postmark Rule Protects You If the Deadline Is Close
Federal law treats a timely postmark as a timely payment. Mail your check on or before the due date with a USPS postmark of that date, and the IRS treats it as paid on the postmark date even if the envelope arrives days later. Designated private delivery services that electronically record their receipt date get the same treatment. Registered or certified mail adds protection: the registration date counts as the postmark date and doubles as proof of delivery.
What Happens If the Check Bounces
A dishonored check or electronic payment triggers a penalty. For payments under $1,250, the penalty is the smaller of the payment amount or $25. For payments of $1,250 or more, it’s 2% of the payment. A bounced $10,000 check costs $200 in penalty alone, on top of the late-payment charges that keep running until the balance is paid. The IRS can waive the penalty if you show reasonable cause to believe the funds were available.
Paying With Cash at a Retail Store
Cash payments start online, not in person. Go to Pay1040 or ACI Payments, select your tax form and year, enter your taxpayer information, and choose the cash option. The processor emails you a payment barcode. Take the barcode and your cash to a participating retail location to complete the transaction.
Each cash payment costs a flat $1.50 service fee and is capped at $500 per payment. Monthly and annual limits also apply, though there’s no daily cap on the number of separate payments. Your barcode expires 20 days after it’s issued, so plan the retailer trip soon after requesting it.
If You Can’t Pay the Full Amount
File the return on time even if the money isn’t there. The failure-to-file penalty runs ten times higher than the failure-to-pay penalty, so skipping the return to buy time makes the bill much larger, not smaller.
Short-Term Payment Plan
If you can clear the balance within 180 days, the IRS offers a short-term plan with no setup fee. Individual taxpayers who owe less than $100,000 in combined tax, penalties, and interest can apply online. Penalties and interest keep accruing during the plan, but there’s no fee for the arrangement itself.
Long-Term Installment Agreement
For balances that need more than 180 days, you can set up monthly payments. The setup fee depends on how you apply and how you’ll pay:
- Direct debit set up online: $22.
- Direct debit set up by phone, mail, or in person: $107.
- Other payment methods set up online: $69.
- Other payment methods set up by phone, mail, or in person: $178.
Applying online with direct debit is by far the cheapest route. Interest and the failure-to-pay penalty continue during an installment agreement, so paying it down faster than the minimum still saves money.
Offer in Compromise
If you genuinely can’t pay the full debt even over time, an Offer in Compromise lets you settle for less. The application fee is $205 and is waived for low-income applicants. The IRS weighs your income, expenses, assets, and ability to pay before accepting, and most offers are rejected. Treat it as a last resort for real hardship, not a general negotiating tactic.
What Late Payments Cost
Missing a deadline triggers two charges that stack. The failure-to-pay penalty is 0.5% of the unpaid tax per month or partial month, up to 25% of the balance. Interest compounds daily on top of that. The individual underpayment interest rate for the first quarter of 2026 is 7% per year. The IRS resets the rate quarterly based on the federal short-term rate, so it can move up or down.
Confirming Your Payment Posted
Processing time depends on how you paid. Direct Pay and EFTPS payments usually show as pending almost immediately and settle within a couple of business days. A mailed check can take several weeks to clear your bank and appear on your IRS account. The IRS recommends waiting at least two weeks before calling about a mailed payment.
The IRS Online Account portal shows up to five years of payment history, current balances by tax year, and any pending or scheduled payments. Keep the confirmation number from your original transaction; it’s the reference you’ll need if something looks wrong. If a payment hasn’t appeared after the expected processing window, call the IRS at 800-829-1040 with the confirmation number ready.
