What You Owe
The IRS measures its eligibility thresholds on the combined balance, so enter the total from your notice, not the tax alone.
Leave this blank and the calculator uses the IRS default minimum, your balance divided by 72.
Plan Type
Recommended follows the IRS eligibility ladder: a 180-day plan when your balance and budget clear it in time, otherwise a long-term agreement. Choose a specific plan to price a 180-day payoff against a multi-year agreement.
Applying online with direct debit is the cheapest route, $29 against $178 at the other corner of the fee table.
Rate and Status
Default: 7% for the quarter beginning Oct 1, 2026 (Rev. Rul. 2026-15). The IRS resets this rate quarterly, so check the current rate and adjust.
Filing on time is what unlocks the reduced 0.25% per month penalty under IRC Section 6651(h). Without it the penalty stays at 0.5%.
Waived entirely with direct debit. Otherwise $43, which may be reimbursed when you finish the plan.
Estimates only. Not tax or legal advice. Actual amounts depend on your exact balance when the IRS approves the plan, the approval date, and the interest rate in effect each quarter. Consult a tax professional. Sources: IRS Payment Plans, IRS Failure to Pay Penalty, IRS Quarterly Interest Rates, IRC Section 6651.
How this estimate simplifies: the failure-to-pay penalty and its 25% cap are computed as though your whole entered balance were tax, so if penalties are already baked into that figure the penalty line is slightly overstated. Each payment is applied to tax first (the IRS order is tax, then penalty, then interest), interest is held at one rate for the whole term when the real rate resets quarterly, and a full month of penalty is charged even for a partial month.

What an IRS payment plan actually costs
An IRS payment plan has three cost layers, and most people only think about the first one.
The setup fee is a single charge at the front. It is $0 for a short-term plan and between $29 and $178 for a long-term installment agreement, depending on how you pay and how you apply. On a five-figure balance it is the smallest of the three layers by a wide margin.
Interest runs at the federal short-term rate plus 3 percentage points for individuals under IRC Section 6621, compounded daily. For the quarter beginning October 1, 2026 that is 7% a year (Rev. Rul. 2026-15). It never stops while a balance is outstanding, and an installment agreement does nothing to reduce it.
The failure-to-pay penalty is 0.5% of the unpaid tax per month under IRC Section 6651(a)(2), capped at 25% of that tax. Once a Section 6159 installment agreement is in effect and you filed the return on time, Section 6651(h) halves it to 0.25% a month. That is a meaningful discount: 3% a year instead of 6%.
Add the two running charges together and the rule of thumb for a long-term agreement is about 10% a year on the unpaid balance: roughly 7% interest plus roughly 3% penalty. That is the number to carry around. Term length moves the total far more than the setup fee does.
Take a $10,000 balance at the IRS default minimum of $139 a month (the balance divided by 72). With about 0.83% of the balance accruing each month against a payment of 1.39%, the balance falls slowly, and 72 months later around $4,000 is still outstanding. Double the payment to $278 and the balance clears in 43 months for a fraction of the carrying cost. Paying more than the minimum is worth that whole gap. The comparison table above recomputes your plan at 1.5x and 2x so you can see it on your own numbers.
Which IRS payment plan you qualify for
Eligibility is a ladder measured on your combined balance: tax plus penalties plus interest, not the tax alone. Working down from the top:
- Under $100,000 and payable inside 180 days: a short-term payment plan, available online, with no setup fee.
- $50,000 or less: a long-term installment agreement that you can set up yourself through the Online Payment Agreement application.
- Over $50,000 but under $100,000: a long-term agreement is still available, but not online. You file Form 9465, and a collection information statement (Form 433-F) is likely. The setup fee falls to the phone and mail tier because the online path is closed.
- $100,000 or more: no online option for either plan type. Expect to call the IRS or work through a representative, and expect financial disclosure.
One rule changed recently. Know it before you apply. The IRS has replaced the Streamlined Installment Agreement and the Express Installment Agreement with a process it calls the Simple Payment Plan (IRM 5.14.1), open to taxpayers with an aggregate unpaid balance of assessment of $50,000 or less. The IRS newsroom guidance still describes monthly payments for up to 72 months and still says direct debit is required for balances of $25,000 to $50,000. Under the Simple Payment Plan the term is generally bounded by the collection statute expiration date rather than a flat 72 months. This calculator keeps 72 months as its projection cap and keeps the $25,000 direct debit prompt, but treats both as advisories rather than hard limits, because a longer term may be negotiable.
Setup fees, the low-income waiver, and the cheapest way to apply
The fee table below is the one published on IRS.gov, last updated March 3, 2026. If you find a page quoting $22 for an online direct debit agreement, it predates that update.
| Plan | How you apply | Direct debit | Check, card or manual |
|---|---|---|---|
| Short-term (180 days) | Online or phone, mail, in person | $0 | $0 |
| Long-term | Online | $29 | $69 |
| Long-term | Phone, mail or in person | $107 | $178 |
| Long-term, low income | Any | $0 (waived) | $43 (may be reimbursed) |
The cheapest path is not subtle: apply online and pay by direct debit. That is $29 against $178 at the opposite corner, a $149 difference for the same agreement. Direct debit also keeps you inside the IRS expectation for balances of $25,000 to $50,000, and it removes the single most common cause of default, a missed manual payment.
The low-income waiver applies when your adjusted gross income is at or below 250% of the applicable federal poverty level. With a direct debit installment agreement the fee is waived outright, with nothing to recover later. Without direct debit you pay $43, which may be reimbursed once you complete the agreement. The IRS identifies most qualifying taxpayers automatically. If it does not identify you, file Form 13844 within 30 days of the notice accepting your agreement.
Changing a plan you already have carries its own price: $89 to revise an existing agreement by phone, mail or in person, $6 to revise it online, and $0 to modify the payment amount or due date on a direct debit agreement. One more reason to set up direct debit.
How to lower what you pay (and what happens if you default)
Four levers move the total, in rough order of how much they are worth.
File on time even when you cannot pay. This is the largest single lever and it costs nothing. The failure-to-file penalty is 5% a month, ten times the failure-to-pay rate, and timely filing is also the condition that unlocks the reduced 0.25% penalty inside an installment agreement. The IRS Late Filing and Late Payment Penalty Calculator puts numbers on the difference.
Pay more than the minimum. Both running charges are proportional to the balance and to the time you carry it, so shortening the term compounds in your favor. Every extra dollar of monthly payment removes more than a dollar of eventual cost.
Ask about penalty relief. First-time abatement is available if you have a clean compliance history for the three prior years, and reasonable-cause relief covers circumstances outside your control. Neither touches interest, which the IRS can only abate in narrow situations, but penalty relief on a large balance is worth the phone call.
Do not let the plan default. A missed payment can put the agreement into default, which brings a reinstatement fee, returns the account to active collection, and reopens the possibility of a levy. After a notice of intent to levy, the failure-to-pay penalty rises to 1% a month, double the standard rate and four times the reduced one.
If the balance came from underwithholding or from self-employment income, a payment plan only handles this year's damage. The IRS Underpayment Penalty Calculator 2026 shows what the shortfall itself cost, the Estimated Quarterly Tax Calculator 2026 sizes next year's payments, and the Free Tax Refund Estimator 2026 tells you where you are heading before the return is due.
Frequently Asked Questions
Common questions about irs payment plan calculator 2026
How much is the IRS payment plan setup fee in 2026?
A short-term plan (180 days or less) has no setup fee. A long-term installment agreement costs $29 if you apply online and pay by direct debit, $69 online without direct debit, $107 by phone, mail or in person with direct debit, and $178 by phone, mail or in person without direct debit. Low-income taxpayers pay nothing with a direct debit agreement and $43 otherwise, which may be reimbursed. Several sites still quote a $22 online direct-debit fee. That figure is out of date: the IRS fee table, last updated March 3, 2026, says $29.
What interest rate does the IRS charge on a payment plan?
Interest runs at the federal short-term rate plus 3 percentage points for individual taxpayers (IRC Section 6621), compounded daily. For the quarter beginning October 1, 2026 that rate is 7% (Rev. Rul. 2026-15, IRB 2026-36). The IRS resets it every quarter, so a multi-year plan spans several different rates and no single figure is correct for the whole term. The rate is an editable input on this page rather than a frozen constant.
Does the failure-to-pay penalty stop if I set up an installment agreement?
No. It keeps running at 0.5% of the unpaid tax per month, capped at 25% of that tax. IRC Section 6651(h) cuts the rate to 0.25% per month, but only for months in which a Section 6159 installment agreement is in effect, and only if you filed the return by its due date including extensions. A short-term 180-day plan is an extension to pay rather than a Section 6159 agreement, so it does not get the reduction. To price the penalty on its own, use the IRS Late Filing and Late Payment Penalty Calculator.
What is the minimum monthly payment on an IRS installment agreement?
If you do not propose an amount, the IRS generally divides your balance by 72. The practical floor is higher than you might expect, because your payment has to beat the penalty and interest accruing each month or the balance never shrinks. At a 7% interest rate with the reduced 0.25% penalty, that break-even point is roughly 0.83% of the balance per month, about $83 on a $10,000 balance. This calculator flags a payment that never amortizes and shows the amount that would actually clear the balance in time.
How long do I get to pay the IRS?
A short-term plan runs up to 180 days. Long-term agreements have historically run up to 72 months. The IRS is moving to a Simple Payment Plan process that replaces the Streamlined and Express Installment Agreements, and under it the term is generally bounded by the collection statute expiration date rather than a flat 72-month cap, so a longer term can be available. This calculator caps the long-term projection at 72 months and reports what would still be outstanding at that point.
What is the difference between a short-term and a long-term IRS payment plan?
Cost, length, and the penalty rate. A short-term plan is free to set up and must be paid inside 180 days, but it keeps the full 0.5% per month failure-to-pay penalty because it is not a Section 6159 installment agreement. A long-term agreement costs $29 to $178 to set up, can run for years, and halves the penalty to 0.25% per month when you filed on time. On a small balance the short-term plan usually wins, because there is no fee to recover. Once the balance is larger the halved penalty can outweigh the fee: on $10,000 cleared over six months with a timely-filed return and the $29 online direct debit fee, the long-term agreement works out about $48 cheaper. Price both.
Can I get the IRS setup fee waived?
Yes, if your adjusted gross income is at or below 250% of the applicable federal poverty level. With a direct debit installment agreement the fee is waived outright. Without direct debit you pay $43, which may be reimbursed once you complete the plan. If the IRS does not identify you as low income automatically, file Form 13844 within 30 days of the notice accepting your agreement.
Is an IRS payment plan cheaper than putting the balance on a credit card?
Usually. On a long-term agreement with a timely-filed return the all-in cost is roughly 7% a year in interest plus about 3% a year in penalty, so around 10%, against card rates that commonly run 20% or more. An IRS installment agreement also does not appear on your credit report, though a filed notice of federal tax lien can. Moving the balance to a card only helps if the card rate is genuinely lower once the balance transfer or convenience fee is counted. The Estimated Quarterly Tax Calculator helps you avoid repeating the problem next year.
