IRS Short-Term Payment Extension: 120-Day Extra Time to Pay
If you owe the IRS but can pay in full within 120 days, the short-term payment extension may be all you need. It is free, requires no financial disclosure, and can be set up in minutes online — avoiding the need for a formal installment agreement.
What Is the Short-Term Payment Extension?
The IRS offers a short-term payment plan (also called a 120-day extension) for taxpayers who can pay their full balance within 120 days. Unlike a formal installment agreement, there is no setup fee and no long-term commitment. Penalties and interest continue to accrue until the balance is paid, but no installment agreement user fee is charged.
Who Qualifies for a 120-Day Extension
Generally, taxpayers with balances under $100,000 (tax, penalties, and interest combined) can set up a short-term plan online without speaking to an IRS representative. Balances over $100,000 require a phone call to the IRS. There is no financial disclosure requirement for the short-term plan.
How to Apply Online
Visit IRS.gov and go to the Online Payment Agreement tool. Select 'short-term payment plan (120 days or less).' Verify your identity and review your balance. Choose a payment start date and method. Receive immediate confirmation. No IRS phone call is needed for most cases.
Short-Term Extension vs. Installment Agreement
The short-term extension is better when: you can genuinely pay in full within 120 days; you want to avoid the installment agreement setup fee ($31 online, $107 by phone); and your balance is modest. An installment agreement is better when: you cannot pay in full within 120 days; you want the protection of a formal collection hold; or the balance requires more than 4 months to pay.
Interest and Penalty Accrual During the Extension
The short-term extension does not stop interest or the failure-to-pay penalty from accruing. Interest is approximately 7–8% annually on the unpaid balance. The faster you pay within the 120 days, the less total interest you owe. Paying in full on Day 1 is always the cheapest option.
Frequently Asked Questions
Does the IRS charge a fee for a short-term payment extension?
No. Unlike a formal installment agreement, the short-term 120-day extension has no setup fee. Penalties and interest continue to accrue on the unpaid balance, but there is no service charge.
What happens if I cannot pay in full by Day 120?
Contact the IRS before the extension expires to convert to a formal installment agreement. Do not simply let the extension lapse — that returns you to the standard notice sequence.
Can I set up the extension online or do I need to call the IRS?
For balances under $100,000, the Online Payment Agreement tool at IRS.gov handles it entirely online without a phone call.
Does a short-term extension stop IRS collection notices?
Yes. Once an extension or payment plan is established, the IRS pauses the notice sequence and does not issue levy notices.
Can I request a short-term extension even if I have already received a CP504 or LT11?
For cases already at the LT11/CP90 stage, an installment agreement is typically more appropriate and provides formal collection hold protection. Call the IRS or consult a professional.
What if I need more than 120 days?
Set up a formal installment agreement instead. For balances under $50,000, you can apply online for up to 72 months. For balances under $100,000, Streamlined Installment Agreements are available for up to 84 months in some cases.
