The IRS Short-Term Payment Plan: Up to 180 Days, No Setup Fee

Not everyone who owes the IRS needs years. A bonus is coming in March. A property sale closes in 90 days. A slow season is about to end. For people who can pay in full within a few months, the IRS offers a short-term payment plan of up to 180 days with no setup fee.

It is a good tool. It is also not what most people think it is. A short-term payment plan is not an installment agreement under IRC 6159, and that changes your rights in ways worth understanding before you choose it.

The basics

According to the IRS payment plans page, last reviewed August 13, 2026, a short-term plan lets you pay within 180 days, carries a $0 setup fee whether you apply online, by phone, by mail or in person, and leaves penalties and interest accruing until the balance is paid. Individuals can apply online if they owe less than $100,000 in combined tax, penalties and interest. Businesses cannot use the online application and call 800-829-4933 instead.

Inside the IRS, the campus procedures in IRM 5.19.1.6.3 say individual and business taxpayers may be granted short-term plans up to 180 days for accounts in notice status or in the collection statuses handled by the Automated Collection System, if no prior short-term plan has been granted. The plan can cover assessed balances and balances not yet assessed.

One at a time, and 180 days means 180 days

The Manual is strict about the clock. Existing short-term plans can be revised to add new balances or extra time, but only so long as the total time to pay does not exceed 180 days from the original request date. If you already used the full 180 days, the IRS will not grant more unless there are unusual circumstances; the IRM names combat zone service and presidentially declared disasters as examples.

A new short-term plan is available only after everything from the prior plan has been paid in full. The IRM's example is a taxpayer who paid 2016 and 2017 balances within 180 days, then filed a 2018 return with a balance due. That taxpayer could get a new 180-day plan for the new balance.

It works for balances not yet assessed

A short-term plan does not have to wait for the IRS to assess the tax. IRM 5.19.1.6.3 allows these plans on assessed or pre-assessed balances, and it specifically includes taxpayers who say they are filing a refund return or an amended return that will pay the balance in full. If you just filed a return with a balance due and know exactly when the money will arrive, you can lock in the arrangement before the first notice is even generated.

What a short-term plan does not do

Here is where the distinction matters. The IRM contains a caution that is easy to overlook: IRC 7122(e)(2) and Treas. Reg. 301.6159-1(e)(5) provide appeal rights associated with an installment agreement that do not apply to short-term payment plans. You can appeal the rejection or termination of an installment agreement. You cannot appeal a short-term plan the same way.

Two other differences follow from the same fact.

• No reduced penalty. The failure-to-pay penalty drops from half a percent to a quarter of a percent a month under IRC 6651(h) only while an installment agreement under section 6159 is in effect. The IRM states plainly that the failure-to-pay rate is not reduced on short-term payment plans.
• No installment agreement levy protection. IRC 6331(k)(2) bars levy while an installment agreement is pending or in effect. A short-term plan is not an installment agreement. In practice the IRS monitors the promised payment date and generally releases levies when it grants the plan, but the statutory bar is not there. The IRM also notes that if the plan is not paid, enforcement may follow, and that a final notice of intent to levy may already be on the account.

The IRM even tells employees not to convert a taxpayer's request for an installment agreement into a short-term plan, and not to grant a short-term plan to someone already in installment agreement status, explaining that a short-term plan does not extend the time for collection appeal rights. The IRS knows the two are different. You should too.

What it costs

No setup fee. That is the main attraction. A long-term installment agreement entered on or after July 5, 2026 costs $29 to $178 depending on how you apply and how you pay; see installment agreement user fees.

But the balance keeps growing. Interest runs at the federal underpayment rate, 7 percent per year compounded daily for October through December 2026. The failure-to-pay penalty runs at half a percent per month of the unpaid tax, and it rises to 1 percent a month beginning 10 days after the IRS issues a notice of intent to levy under IRC 6651(d). On a $20,000 balance over six months, the penalty difference between a short-term plan and an installment agreement for someone who filed on time is real, though usually smaller than the setup fee you save. Run both scenarios in the payment plan calculator.

When to choose which

Choose a short-term plan when you are confident you can pay everything within 180 days, the balance is modest, and no levy is underway. It is fast, it is free to set up, and it does not lock you into monthly installments.

If you do take a short-term plan, ask for the payoff figure computed to your payment date. IRM 5.19.1.6.3 tells employees to compute the payoff to the full pay date. Paying the amount on an old notice weeks later leaves a tail of additional interest, and that small leftover balance can start the notice cycle all over again.

Choose a long-term installment agreement when there is real doubt about the 180 days, when a final notice of intent to levy has already been issued and you want the statutory levy bar, or when the balance is large enough that the reduced failure-to-pay rate outweighs the setup fee. You can always pay a long-term plan off early. The IRM reminds employees that while an existing installment agreement cannot be converted to a short-term plan, a taxpayer may submit full payment at any time.

If you start with a short-term plan and it becomes clear you cannot finish, do not let it lapse. Call before the deadline and ask for an installment agreement. A Simple Payment Plan is available on assessed balances of $50,000 or less without a financial statement, as long as all required returns are filed.

How to set one up

Individuals can request a short-term plan through their IRS online account. You can also call the number on your notice. When the IRS grants a short-term plan by phone on a notice-status account, the IRM directs employees to send Letter 681-C confirming the payment date, the amount due computed to that date, and where to send the payment. Keep that letter.

If you have unfiled returns, the IRS can still grant a short-term plan if you meet the other criteria, but it will set a firm deadline for filing the missing returns. Meet it. A missed filing deadline on top of a short-term plan is the fastest way to end up back in enforcement.

The bottom line

The short-term plan is a promise to pay, written down. It is not a contract with the protections Congress attached to installment agreements. For a quick, certain payoff, it is the cheapest tool the IRS offers. For anything less certain, the installment agreement's appeal rights, levy bar and reduced penalty are worth the setup fee.
