The IRS will let you pay what you owe in monthly installments instead of a lump sum, but you have to request it and meet their terms

If you owe federal income tax and cannot pay the full amount by the important date, the IRS offers installment agreements that let you pay in smaller monthly chunks. You do not have to wait for a bill or a notice — you can request a plan before the IRS contacts you, and doing so often stops penalties and interest from growing as quickly. The process is straightforward: you tell the IRS how much you owe, how much you can pay each month, and they either approve it or counter with a different amount. Most people set these up online through the IRS website, by phone, or by mail.

The catch is that interest and penalties keep accruing while you pay, so a longer plan costs more overall. The IRS also charges a setup fee (usually $31 to $225 depending on the method you use) and will not approve a plan if your monthly payment is too low relative to what you owe. If your situation changes — you lose income or get a raise — you can modify the plan, but you have to contact the IRS to do it.

Key Takeaways

  • You can set up an installment agreement online at IRS.gov, by calling 1-800-829-1040, or by mailing Form 9465 to the address on your tax bill.
  • The IRS charges a setup fee ranging from $31 to $225 depending on whether you use online, phone, or mail, and whether you set it up before or after the IRS contacts you.
  • Your monthly payment must be high enough that you will pay off the debt within six years; the IRS will reject plans where the payment is too small.
  • Interest and penalties continue to accrue on the unpaid balance, so paying faster saves you money even though the monthly payment is lower.
  • If your income or expenses change, you can request a modification by contacting the IRS, but the plan does not adjust automatically.

Three ways to request an installment agreement

The fastest and cheapest route is online through IRS.gov. Go to the IRS Online Payment Agreement tool, enter your Social Security number, filing status, and tax year, and the system will show you what you owe and let you choose a monthly payment amount. You will get when ready approval or denial, and if approved, the plan starts when ready. The setup fee is $31 for online agreements. You need a valid email address and access to a computer or phone.

If you cannot or prefer not to use the online tool, you can call the IRS at 1-800-829-1040. A representative will walk you through the same information and set up the plan over the phone. The setup fee is $225 for phone agreements. Wait times vary; calling early in the morning or mid-week usually means shorter holds. Have your Social Security number, filing status, and a sense of what monthly payment you can afford before you call.

You can also mail Form 9465 (Installment Agreement Request) to the address shown on your tax bill or notice. Include a cover letter stating the monthly payment you propose and why you cannot pay in full. Mail it to the address listed on your bill, not the general IRS address. Processing by mail takes four to six weeks. The setup fee is $31 for mail agreements if you submit the form before the IRS contacts you; it rises to $225 if you submit it after receiving a bill or notice.

What the IRS needs from you before approving a plan

The IRS will ask for your total tax debt, your monthly income, and your monthly expenses. You do not need to provide detailed documentation upfront — the online tool and phone representatives will calculate a minimum monthly payment based on how much you owe and how long you want to take to pay it. If you owe less than $50,000, the IRS will usually approve a plan with a payment that spreads the debt over up to six years. If you owe more, the rules are stricter and you may need to provide financial information to justify a lower payment.

The IRS will reject a plan if your proposed monthly payment is too low. There is no published formula, but as a rough guide, if you owe $10,000 and propose a $50 monthly payment, the IRS will likely counter with a higher amount or deny the request. The system is designed to may support you are making meaningful progress toward paying off the debt. If the IRS rejects your first proposal, you can resubmit with a higher monthly payment or contact them to discuss your financial situation.

If you are setting up a plan after the IRS has already sent you a bill or notice, you may be asked to provide proof of income (a recent pay stub or tax return) and a list of monthly expenses. This is more common for larger debts or if you have a history of missed payments. The online tool will tell you whether documentation is needed before you submit.

How much the plan costs and what happens to interest and penalties

The setup fee is the first cost: $31 online or by mail (if submitted before IRS contact), $225 by phone or by mail (if submitted after IRS contact). This is a one-time charge added to your balance or deducted from your first payment, depending on the plan type.

The larger cost is interest and penalties. The IRS charges interest on the unpaid balance at a rate set quarterly — currently around 8% per year, though it changes. You also owe penalties: a failure-to-pay penalty of 0.5% per month on the unpaid amount (capped at 25% total), and possibly a failure-to-file penalty if you did not file a return. These penalties and interest keep accruing every month until the debt is paid in full, even while you are on a payment plan. A longer plan means more months of interest and penalties, so paying $500 a month for two years costs less in total interest than paying $250 a month for four years, even though the monthly payment is lower.

You cannot avoid the interest and penalties by setting up a plan, but you can reduce them by paying faster. If you come into money or your income increases, you can pay a lump sum toward the balance at any time without penalty.

What happens after the IRS approves your plan

Once approved, you will receive a confirmation letter with your agreement number, the monthly payment amount, and the due date each month. The payment is usually due on the 28th of each month, though you can request a different date. You can pay by check, electronic bank transfer (ACH), credit or debit card (though there is a processing fee), or through the IRS payment portal.

The IRS will not send you a bill each month — it is your responsibility to pay on time. If you miss a payment, the plan can be terminated and the IRS can resume collection action, including wage garnishment or bank levy. If you know you will miss a payment, contact the IRS before the due date to request a temporary adjustment or extension.

If your financial situation changes — you lose your job, get a raise, or have a major expense — you can request a modification. Call 1-800-829-1040 or use the online tool to request a change in the monthly payment amount. The IRS will not automatically adjust the plan; you have to ask.

When a payment plan might not be your best option

If you owe a very large amount (over $50,000), a standard installment agreement may not be available, and the IRS may require you to explore other options like an Offer in Compromise (settling for less than you owe) or a Currently Not Collectible status (pausing collection while you recover financially). These are separate processes with different rules and timelines.

If you are in active bankruptcy, you cannot set up an IRS payment plan until the bankruptcy is resolved. The IRS is bound by the bankruptcy court's decisions about your debts.

If you have unpaid taxes from multiple years, the IRS will combine them into one plan. This can mean a higher monthly payment than if you addressed each year separately, but it simplifies the process.

Modifying or ending your payment plan

You can change your monthly payment amount at any time by calling the IRS or using the online tool. If you want to pay off the plan early, you can send a lump sum payment at any time — there is no prepayment penalty. The IRS will explore the payment to the oldest tax year first, then work forward.

If you miss three consecutive payments, the IRS will terminate the plan and resume collection action. If this happens, you can request a new plan, but the IRS may be less flexible with the terms. If your plan is terminated and you want to set up a new one, contact the IRS as soon as possible.

If you pay off the plan in full, the IRS will send you a letter confirming the debt is satisfied. Keep this letter for your records.

Frequently Asked Questions

Can I set up a payment plan if I have not filed my tax return yet?

No. You must file your return first so the IRS knows what you owe. If you have not filed, contact a tax professional or the IRS to file before requesting a payment plan. Filing late will add penalties, but filing is the first step.

What if I cannot afford the minimum monthly payment the IRS suggests?

Contact the IRS at 1-800-829-1040 and explain your situation. If you have very low income or high expenses, you may be able to request a lower payment or a Currently Not Collectible status, which pauses collection temporarily. You will still owe the debt, but the IRS will not pursue collection while your finances improve.

Will setting up a payment plan stop the IRS from garnishing my wages or levying my bank account?

If you set up a plan before the IRS takes collection action, it will prevent garnishment and levies. If the IRS has already started collection, setting up a plan will usually stop it, but contact the IRS when ready to confirm. Provide your agreement number once it is issued.

Can I set up a payment plan for someone else's tax debt?

No. Only the person who owes the tax can request a payment plan. If you are a spouse, family member, or representative, you can help gather information, but the taxpayer must authorize and sign the agreement.

What if my payment plan is approved but I lose my job the next month?

Contact the IRS when ready and request a modification or a temporary pause. Explain your situation and ask about a lower payment or Currently Not Collectible status. The IRS has options for people whose circumstances change, but you have to reach out before you miss payments.
