An IRS payment plan, formally called an installment agreement, lets a taxpayer who cannot pay a federal tax bill in full settle it through scheduled payments set with the Internal Revenue Service (IRS). The agreed plan replaces immediate full payment with a timetable. There are two structures: a short-term plan and a long-term plan that spreads repayment over a longer period through recurring payments.
What is an IRS payment plan?
An installment agreement is a formal arrangement with the IRS. Once it is in place, you repay the balance in parts rather than in one lump sum, and the agreed schedule governs how the debt is cleared.
How payments are scheduled
The schedule depends on the plan type. A short-term plan requires the full balance within 180 days or less, so the repayment window is fixed and short. A long-term plan divides the balance into payments made over a longer period. Long-term payments can be made by direct debit, which means they are drawn automatically from a bank account, or by other payment methods.
What the balance covers
The amount to repay is not limited to the tax shown on your return. The balance combines three components:
- Tax: the unpaid federal tax for the period.
- Penalties: additional amounts the IRS adds to the unpaid tax.
- Accrued interest: interest that has built up on the outstanding amount.
Both plan types cover the same combined balance. The difference lies in how that balance is repaid.
Short-term versus long-term structure
| Feature | Short-term plan | Long-term plan |
|---|---|---|
| Repayment window | Full balance within 180 days or less | Balance repaid over a longer period |
| Payment pattern | Balance paid in full within the deadline | Scheduled recurring payments |
| Balance covered | Tax, penalties and accrued interest | Tax, penalties and accrued interest |
The structural difference is timing. A short-term plan compresses repayment into a fixed deadline, while a long-term plan trades a shorter deadline for a spread-out schedule.

Who qualifies for a short-term or long-term plan?
The IRS sets two debt ceilings, and the amount you owe decides which plan you can request. The short-term plan is for balances under USD 100,000. Individuals can apply online for it, and it carries no setup fee. The long-term plan is for combined balances of USD 50,000 or less, which the IRS counts as tax, penalties and interest together. The long-term ceiling counts tax, penalties and interest combined.
| Plan | Debt ceiling | Other condition from the IRS fact sheet |
|---|---|---|
| Short-term | Under USD 100,000 owed | Pay in full within 180 days or less |
| Long-term | USD 50,000 or less, combined tax, penalties and interest | All required returns filed |
The all required returns filed condition is stated for the long-term plan. Before you apply, confirm that every return you are legally required to file has been submitted, because a missing return blocks the request.
A balance just below USD 50,000 at one point can cross the long-term ceiling later. Check the current total with the IRS before choosing a plan, not the amount on the original notice.
How do you apply online, by phone or by mail?
The IRS fact sheet dated 2026-08-13 lists three ways to request a long-term payment plan: through your IRS online account, by phone at 800-829-1040 (for individuals), or by mail with Form 9465. Choose one channel and use only that route for your request. Eligibility rules determine which plan types you can request, so confirm that before you start.
- Online (IRS online account): Sign in to your personal IRS online account and submit the payment plan request there. The fact sheet does not name a separate form for this route.
- Phone (800-829-1040, individuals): Call this number to request the plan. The fact sheet specifies this line for individuals.
- Mail (Form 9465): Complete Form 9465, the installment agreement request form, and send it to the IRS. The fact sheet also states that Form 433-F may be needed, so check whether the IRS asks for it before you mail your request.
Before you choose a channel, gather the tax years and amounts you owe, along with the notices you have received. Keeping these figures together helps you answer questions consistently, whether you submit online, speak with an IRS representative, or fill in a paper form.
The mail route takes the most preparation. Because Form 433-F may be required in addition to Form 9465, verify the requirement against the IRS instructions for your case before you send anything. Keep a copy of everything you submit, including the date you sent it, so you can show what you requested if the IRS contacts you later.
How much does an IRS payment plan cost?
The setup fee depends on three factors: the plan type, the payment method, and the channel used to apply. Long-term plans carry a setup fee, while short-term plans do not.
Long-term plan fees apply to balances of USD 50,000 or less in combined tax, penalties and interest, for taxpayers who have filed all required returns.
| Payment method | Applied online | Applied by phone, mail or in person |
|---|---|---|
| Direct debit | USD 29 | USD 107 |
| Any other method | USD 69 | USD 178 |
Direct debit is the cheaper option in both channels, and online applications cost less than phone, mail or in-person applications for either payment method.
Short-term plans: individuals who owe less than USD 100,000 can apply online.
Low-income reduction applies to long-term plans for taxpayers whose adjusted gross income is at or below 250% of the federal poverty level. The setup fee is USD 43, which may be reimbursed. The fee is waived for direct debit plans.
Do interest and penalties still apply?
Yes. Entering a payment plan does not stop interest and penalties. Both keep accruing on the unpaid balance until the full amount is paid. Monthly installments reduce the principal, but the amount still owed continues to grow while any part of the balance remains outstanding.
The result depends on when the balance is cleared:
| Situation | What happens to interest and penalties |
|---|---|
| Balance still partly unpaid | Both keep accruing on the outstanding amount |
| Balance paid in full | Accrual stops once the balance reaches zero |
| Balance paid early | Less time elapses for charges to accumulate, so the total interest is lower |
Early full payment reduces the total interest. Interest accrues on the balance that remains, so a shorter repayment period means fewer months of accrual. If you can pay more than the scheduled installment, applying the extra amount to the remaining balance lowers the base on which future interest is calculated.
Because the charges continue, the amount you owe on a given day is not the sum of your original installments. Before making a large payment, check the current balance in your IRS online account or ask the IRS for the exact payoff figure, since it includes interest and penalties accrued up to the payment date.
What if you can’t afford the payments?
When a monthly amount no longer fits your budget, the key step is to contact the IRS before the payment is missed, not after. The fact sheet lists its channels for applying, so confirm which one handles changes to an existing plan.
Contacting the IRS before a payment is missed
Contact the IRS as soon as you expect a shortfall. Note the date, the channel used, and the name or reference of the person you spoke with. Keep these notes with your payment records.
Requesting a revised monthly payment amount
Ask for a new monthly amount that matches what you can pay. The fact sheet does not describe the procedure for revising an existing plan, so ask the IRS to confirm the process and any documents it requires before you send anything.
Consequences of defaulting on the agreement
The fact sheet does not describe what happens if you default, so check the terms in your acceptance letter and contact the IRS promptly about any missed payment. A missed payment leaves a larger balance outstanding for longer, and interest and penalties keep accruing until the balance is paid in full.
Key dates to remember
The IRS fact sheet sets two deadlines that govern timing: a 180-day window for paying a short-term plan in full, and a 30-day period to file Form 13844 for a low-income long-term plan. Each one counts from a different reference point, so track them separately.
| Deadline | Applies to | Period | Reference point |
|---|---|---|---|
| Full payment of the balance | Short-term plan | Within 180 days or less | Not stated in the source fact sheet |
| Filing Form 13844 | Long-term plan, when the IRS did not flag you as low-income | Within 30 days | Acceptance letter date |
Short-term plan: the 180-day window
The short-term option covers individuals who owe less than $100,000. The 180 days are a maximum, so paying sooner shortens the arrangement. The fact sheet does not state the day the window begins, so confirm the start date with the IRS before you calculate your own deadline.
Form 13844: the 30-day filing period
Form 13844 applies to low-income long-term plans, where adjusted gross income is at or below 250% of the federal poverty level. It only applies if the IRS did not already flag you as low-income. In that case, you can file within 30 days of the acceptance letter date. The clock is tied to the letter’s date, not to when you start the application or when you mail the form.
Working out your dates
- Find the acceptance letter date for a long-term plan and record it.
- Add 30 days to that date to get the Form 13844 filing cutoff, if the form applies to you.
- For a short-term plan, confirm the start of the 180-day window with the IRS, then count 180 days forward.
- Enter both dates in your calendar with a reminder a few days ahead.
Frequently asked questions
Can I set up an online long-term plan if I owe more than $50,000?
No. The online long-term plan is available only when your combined tax, penalties and interest total $50,000 or less, and all required returns have been filed. Above that threshold, the fact sheet does not list an online route, so check the IRS requirements for your balance before you apply.
How much does setting up a plan cost?
The setup fee depends on how you apply and how you pay. A long-term plan with direct debit costs $29 online or $107 by phone, mail or in person, while other payment methods cost $69 online or $178 by the other channels. Low-income applicants pay $43, and that fee is waived for direct debit. If the IRS did not flag you as low-income, you can file Form 13844 within 30 days of the acceptance letter.
Does the balance keep growing while I pay?
Yes. Penalties and interest continue to accrue until the full balance is paid, so an installment plan does not freeze the amount owed. The total you repay will therefore be higher than the original tax if the balance remains open for a long period.
