The EFTPS PIN letter is a four-digit security code that the U.S. Treasury mails to your IRS address of record after you enroll in the Electronic Federal Tax Payment System. It normally arrives within five to seven business days, and you need it to activate your account before you can schedule any payments.1Electronic Federal Tax Payment System (EFTPS). Welcome to EFTPS Online If it never shows up or you misplace it, you can request a replacement by calling the EFTPS voice response system at 1-800-555-3453 or customer service at 1-800-555-4477.
When the Letter Arrives and Where It’s Sent
After you submit an EFTPS enrollment online at EFTPS.gov or by paper form, the system validates your information with the IRS and generates the four-digit PIN. The package then goes out by standard U.S. Mail to whatever address the IRS already has on file for you, and typically lands in five to seven business days.1Electronic Federal Tax Payment System (EFTPS). Welcome to EFTPS Online Mailing to the address of record is a deliberate security check: it confirms the person enrolling is the actual taxpayer.
That design is also where most delivery problems start. If the IRS has an old address for you, the letter goes to the wrong place and you’ll wait without knowing why. Individuals update their address using Form 8822; businesses use Form 8822-B. Both take four to six weeks to process.2Internal Revenue Service. Form 8822, Change of Address If you’ve moved recently, get the address change in before you enroll.
Activating Your Account Once the Letter Arrives
The PIN itself doesn’t let you pay taxes. You still have to activate the account, which happens in two steps.
First, call 1-800-555-3453 and enter your EIN or Social Security Number along with the four-digit PIN from the letter. From outside the U.S., call 303-967-5916 instead.3Department of the Treasury. How To Activate Your EFTPS Enrollment This links your credentials so the system recognizes you.
Second, go to EFTPS.gov, click “Log In,” select “Need a Password,” and follow the prompts to create an Internet password. You’ll be redirected to register with either Login.gov or ID.me for multi-factor authentication, which EFTPS has required since October 2023.1Electronic Federal Tax Payment System (EFTPS). Welcome to EFTPS Online After that, log in with your EIN or SSN, the four-digit PIN, and your new password. Payments must be scheduled by 8:00 p.m. Eastern Time at least one calendar day before the tax due date.4Fiscal.Treasury.gov. Your Guide for Paying Taxes
If the Letter Never Arrives or You Lost It
Call the EFTPS voice response system at 1-800-555-3453 to request a replacement, or reach a live agent at 1-800-555-4477.1Electronic Federal Tax Payment System (EFTPS). Welcome to EFTPS Online Have your Taxpayer Identification Number ready. A representative may also ask for details like the amount and date of a recent tax deposit to confirm you’re authorized on the account.
Requesting a new PIN immediately cancels any previously issued, unactivated PIN, so if the original letter later turns up, it won’t work. The replacement is mailed the same way and takes another five to seven business days. If a tax deadline falls inside that window, ask the representative whether they can help you schedule an urgent payment over the phone.
Paying Taxes While You Wait
A pending deadline won’t wait for the mail. Two options work without EFTPS access.
IRS Direct Pay for Individuals
Individual taxpayers can use IRS Direct Pay to pay directly from a checking or savings account with no enrollment. You can make up to two payments per day and schedule them up to 365 days in advance.5Internal Revenue Service. IRS Offers Several Payment Options, Including Help for Taxpayers Struggling to Pay Direct Pay is not available for business tax deposits.
Same-Day Wire for Businesses
Businesses facing a deposit deadline can use a same-day wire through their bank. Download the IRS Same-Day Taxpayer Worksheet, fill it in with your payment details, and take it to your financial institution.6Internal Revenue Service. Same-Day Wire Federal Tax Payments Call your bank first to confirm availability, fees, and cutoff times. If you’re paying more than one tax type or period, each needs its own worksheet.
Late-Deposit Penalties and Reasonable-Cause Relief
A missing PIN doesn’t automatically excuse a late deposit. The IRS applies a tiered failure-to-deposit penalty:
- 1 to 5 days late: 2% of the unpaid amount
- 6 to 15 days late: 5% of the unpaid amount
- More than 15 days late: 10% of the unpaid amount
- 15% if the tax remains undeposited 10 days after the IRS issues a delinquency notice
These come from the failure-to-deposit rules and apply to the amount that should have been deposited on time.7Office of the Law Revision Counsel. 26 USC 6656 – Failure to Make Deposit of Taxes
If a PIN delay genuinely caused the late payment, you can request penalty relief for reasonable cause. The IRS treats system issues that delayed a timely electronic payment as a potentially valid reason.8Internal Revenue Service. Penalty Relief for Reasonable Cause Explain what happened and when, describe the steps you took to pay on time (requesting a replacement PIN, attempting a same-day wire or Direct Pay), and attach documentation such as copies of correspondence with EFTPS. The IRS looks at whether you exercised ordinary care despite the obstacle, so evidence that you tried an alternative payment method strengthens the case considerably.
