How to Set Up an IRS Tax Payment Arrangement (and What to Do If You Fall Behind)

If you owe the IRS more than you can pay today, an IRS tax payment arrangement lets you pay the balance off over time instead of all at once. The IRS offers three routes: pay in full, a short-term plan that clears the balance in 180 days or less, or a long-term plan — an installment agreement — that you pay monthly.

Most people can set one up themselves in a few minutes through their IRS online account. If you owe $50,000 or less in combined tax, penalties and interest and you have filed all your required returns, you can request a long-term plan online. For a short-term plan, the online threshold is a balance under $100,000, and only individuals can apply that way. Below is what each option costs, how to apply, and what happens if you fall behind on a plan you already have.

The three IRS payment arrangement options

Which option you land in is driven mostly by how fast you can clear the balance.

• Pay in full. You settle the whole amount now. No setup fee, and penalties and interest stop accruing once the balance hits zero.
• Short-term payment plan. You pay the balance in 180 days or less. There is no setup fee for a short-term plan, whether you request it online, by phone, by mail or in person.
• Long-term payment plan (installment agreement). You pay monthly until the balance is cleared. This one carries a setup fee, and the amount depends on how you apply and how you pay.

Sole proprietors and independent contractors apply as individuals, which matters because the individual thresholds and the online short-term option are more generous.

Who can set up an IRS payment plan online

Applying online is the cheapest route by a wide margin, so check whether you qualify before picking up the phone.

• Long-term plan: you owe $50,000 or less in combined tax, penalties and interest, and you have filed all required returns.
• Short-term plan: you owe less than $100,000 in combined tax, penalties and interest. Individuals only.

That filing requirement trips up more people than the dollar threshold does. The IRS will not approve an installment agreement while returns are missing, however reasonable the monthly payment you are offering. Unfiled years have to be dealt with first.

What an IRS tax payment arrangement costs

Setup fees

A short-term plan has a $0 setup fee however you request it. Long-term installment agreements are where the fees live, and the spread between the cheapest and most expensive version is significant:

• Direct Debit Installment Agreement (DDIA) — automatic monthly payments from a checking account: $29 applied online, $107 by phone, mail or in person.
• Any other payment method — Direct Pay, EFTPS, check, money order or card: $69 applied online, $178 by phone, mail or in person.
• Changing an existing plan: $6 online or $89 by phone, mail or in person. Changes to an existing DDIA are $0.

The same agreement costs $29 online with direct debit and $178 by phone with another payment method — the easiest cost in this process to avoid.

Taxpayers the IRS identifies as low income — adjusted gross income at or below 250% of the applicable federal poverty level — have the setup fee waived entirely on a direct debit agreement. If you cannot use direct debit, the fee is $43 and may be reimbursed when the agreement is completed. If the IRS did not flag you as low income and you believe you qualify, you can submit Form 13844 within 30 days of the date on your installment agreement acceptance letter.

Interest and penalties while you’re on a plan

A payment arrangement is not a freeze. The IRS is explicit that interest and some penalty charges continue to be added to what you owe until the balance is paid in full. A plan stops enforced collection; it does not stop the meter.

There is one meaningful break. The failure-to-pay penalty normally runs at 0.5% of the unpaid tax for each month or part of a month, capped at 25% of the unpaid amount. For an individual who filed the return on time, that rate is reduced to 0.25% per month during an approved payment plan. Filing on time even when you cannot pay is what buys you that halved rate — another reason not to let a return go unfiled because the balance scares you.

It runs the other way too. If the IRS has issued a notice of intent to levy and the balance is not paid within 10 days, the failure-to-pay penalty rises to 1% per month or partial month.

How to apply for an IRS payment arrangement

1. File everything first. All required returns must be filed before an installment agreement will be approved.
2. Work out what you can actually pay each month. There is no official IRS calculator that sets the number for you. A long-term plan generally needs to clear the balance within the time the IRS has left to collect, so start from your balance and a monthly amount you can sustain.
3. Apply online if you qualify. Use your IRS online account. This is the lowest-fee route.
4. Or apply by phone: 800-829-1040 for individuals, 800-829-4933 for businesses. Businesses can also visit a Taxpayer Assistance Center.
5. Or apply by mail using Form 9465, Installment Agreement Request, which is used to request a monthly installment plan when you cannot pay the full amount shown on your return or on a notice. Some applicants also have to submit Form 433-F, a collection information statement. Certain applicants are required to go the mail route rather than applying online.
6. Choose direct debit if you can. Lowest fee, lowest chance of an accidental default.

What happens if you miss a payment

This is where a lot of payment arrangements quietly come apart. An agreement can default for three reasons, and only one is the obvious one:

• Not paying at least the minimum monthly payment when it is due.
• Not filing all required returns on time — including the ones for years after the agreement started.
• Not paying all taxes in full and on time, which means a new balance on a later year can default a plan you have never missed a payment on.

The second and third catch people out: you can be current on every monthly payment and still default the agreement by owing on the following year’s return.

Once a plan defaults, penalties and interest keep accruing, you may owe a fee to reinstate it, and future refunds are applied to the tax debt until it is paid in full.

The CP523 notice

If the IRS decides to end your agreement, it sends Notice CP523. It says the IRS intends to terminate your installment agreement and levy your assets. Contact the IRS no later than 30 days from the date of the notice — and read the notice itself, because it may list an earlier termination date than you expect.

If you do nothing, the IRS can terminate the agreement and begin collection, which can include filing a federal tax lien or levying wages and bank accounts. Under the FAST Act, seriously delinquent tax debt can also lead the State Department to deny or revoke a passport.

Getting a terminated agreement reinstated

A CP523 is not the end of the road. You can pay before the termination date to keep the agreement alive, or contact the IRS about reinstating it — which may require a reinstatement fee or paying any new tax owed in full. If you have already fixed the problem, call anyway so the IRS can record it.

If you disagree with the IRS’s reason for terminating, you can call the number on the notice, and if that does not resolve it, request a hearing with the IRS Independent Office of Appeals.

When a payment plan isn’t the right answer

An installment agreement works when the balance is payable over time and your income supports the monthly number. It fits poorly when the payment the IRS expects is more than you can sustain, when unfiled years have to be resolved first, or when your circumstances point to a different collection option.

Alternatives such as an offer in compromise, currently not collectible status or penalty abatement each carry their own eligibility rules. A payment plan is one option among several, not the only door — and setting up an agreement you cannot keep is worse than finding the one that fits, because a defaulted plan puts you back in collection.

Frequently asked questions

How do I set up a tax payment plan?

File all required returns, then apply through your IRS online account if you owe $50,000 or less for a long-term plan or under $100,000 for a short-term plan. You can also apply by phone at 800-829-1040 or by mailing Form 9465.

How much interest does the IRS charge for a payment plan?

Interest continues to accrue on the unpaid balance until it is paid in full, and the rate is set quarterly rather than fixed for the life of the agreement. Separately, the failure-to-pay penalty runs at 0.5% per month, reduced to 0.25% per month during an approved plan if you filed your return on time.

Is there an IRS installment agreement calculator?

The IRS does not publish a calculator that sets your monthly payment. The online application will show you what it will accept based on your balance, and a mailed request using Form 9465 lets you propose a monthly amount.

Can the IRS deny a payment plan?

Yes. The most common reason is unfiled returns — the IRS requires all required returns to be filed before approving an installment agreement. A balance above the online thresholds, or a prior defaulted agreement, can also mean the request is handled differently or requires a collection information statement.

What happens if you miss an IRS installment payment?

The agreement can go into default. Penalties and interest continue, a reinstatement fee may apply, and future refunds are applied to the debt. If the IRS moves to end the agreement it issues Notice CP523, giving you 30 days from the date of the notice to respond — though the notice may list an earlier termination date.

What is the IRS application for a payment plan?

Online, it is the Online Payment Agreement application in your IRS account. On paper, it is Form 9465, sometimes submitted with Form 433-F.
