You can modify your payment plan by contacting the IRS directly, either by phone, mail, or through your online account

If your financial situation has changed since you set up your payment plan — you lost income, got a raise, or an unexpected expense came up — the IRS lets you change the terms. You can increase or decrease your monthly payment, extend the plan, switch from one type of plan to another, or cancel it altogether. The process is straightforward, but the method you use and how long it takes depends on which route you choose.

The fastest way is usually by phone. You can reach the IRS at 1-800-829-1040 (the main customer service line) and ask to modify your existing plan. Have your Social Security number, the tax year the debt is from, and your current plan details ready. If you set up your plan online through IRS.gov, you can also log into your account and make some changes yourself without calling.

Key Takeaways

  • You can change your monthly payment amount, extend your plan timeline, or switch plan types by calling 1-800-829-1040 or logging into your IRS online account.
  • The IRS will recalculate what you owe if your income or expenses have changed significantly, which may lower your required payment.
  • If you want to cancel your plan entirely, you can pay the full balance at once or request that the IRS place your account in currently not collectible status if you cannot pay.
  • Mailing a request takes longer than calling or using your online account, typically four to six weeks for the IRS to process.
  • If your plan fails because you miss a payment, the IRS will contact you about reinstating it or setting up a new one.

Changing your monthly payment amount

The most common revision is adjusting how much you pay each month. If you received a raise or your expenses dropped, you might want to pay more to finish faster and pay less interest overall. If you lost a job or had a medical emergency, you might need to pay less.

When you call the IRS or log into your account, tell them your new proposed payment amount. The IRS will check whether it fits within their rules — generally, your payment must be at least enough to cover the monthly interest and penalties accruing on your debt, though there are exceptions for hardship situations. If your income has dropped significantly, you can request a financial statement review, where the IRS looks at your actual income and expenses and may lower your payment to what you can realistically afford.

If you are on an installment agreement (the most common type), you can usually change your payment amount once per year without penalty. If you want to change it more often, the IRS may charge a small fee, typically $25 to $225 depending on the method and your income level.

Extending or shortening your plan timeline

Your original plan has an end date — usually somewhere between 24 months and 72 months depending on how much you owe and which plan type you chose. If you need more time, you can ask to extend that date, which lowers your monthly payment but increases the total interest you pay.

Conversely, if your situation improved and you want to finish paying faster, you can shorten the timeline. This raises your monthly payment but saves you money on interest. Both changes are handled the same way: call the IRS, log into your account, or mail a written request. The IRS will recalculate your payment based on the new end date and send you an updated agreement.

Switching between plan types

The IRS offers several plan types: standard installment agreements (fixed payment each month), short-term extensions (120 days or less to pay in full), and income-driven plans where your payment is based on what you actually earn. If your circumstances have shifted, a different plan type might work better.

For example, if you were on a standard plan but your income is now unpredictable, you might switch to an income-driven plan where your payment adjusts each year based on your tax return. Or if you were on an income-driven plan and now have stable income, switching to a standard plan might let you pay off the debt faster with a fixed amount.

To switch plans, contact the IRS using any of the methods below. They will terminate your current plan and set up a new one. There is usually no fee to switch, though you may be charged a setup fee for the new plan if you are setting it up for the first time (typically $31 to $225 depending on the method).

Canceling your plan entirely

If you want to stop making monthly payments, you have two main options. The first is to pay the full remaining balance in one lump sum. This ends the plan when ready and stops any further interest from accruing. If you received a tax refund, inheritance, or bonus, this is often the cleanest choice.

The second option is to request currently not collectible status. This pauses your plan temporarily — you stop making payments, but the IRS also stops collection efforts against you. Interest and penalties continue to accrue, and the debt remains on your account. The IRS will review your case periodically (usually every two years) to see if your situation has improved. If it has, they will restart your plan. If you remain unable to pay, the status can continue until the debt expires under the statute of limitations, which is typically ten years from the date the IRS assessed the tax.

Currently not collectible status is not forgiveness — you still owe the debt — but it gives you breathing room if you are facing genuine hardship. To request it, call the IRS or mail Form 433-F (Collection Information Statement for Wage Earners) along with a letter explaining your situation.

How to contact the IRS to revise your plan

By phone: Call 1-800-829-1040 Monday through Friday, 7 a.m. to 7 p.m. your local time. Wait times are often shorter early in the morning or late in the day. Have your Social Security number, the tax year, and your current plan details ready.

Online: If you set up your plan through IRS.gov, log into your account at irs.gov/payments. You can view your plan details and make certain changes (like adjusting your payment date) directly. More complex changes, like extending the timeline or switching plan types, may require a phone call.

By mail: Write a letter to the IRS explaining what you want to change. Include your name, Social Security number, the tax year, your current payment amount, and what you are requesting. Mail it to the address shown on your most recent IRS notice. This method takes four to six weeks to process.

In person: You can visit a local IRS office, though appointments are limited and wait times can be long. Call 1-800-829-1040 to schedule an appointment.

What happens if you miss a payment on your plan

If you miss a payment, your plan does not automatically fail. The IRS typically allows a grace period of a few days. However, if you miss a payment by more than 30 days, the IRS may terminate your plan and treat the entire remaining balance as due when ready.

If this happens, the IRS will send you a notice. You can request to reinstate your original plan or set up a new one. If you are having trouble making your payment, contact the IRS before you miss it — they are often willing to work with you if you reach out proactively. You can request a temporary pause, a lower payment, or a different arrangement.

Frequently Asked Questions

Does the IRS charge a fee to change my payment plan?

Not always. Changing your payment amount once per year is free. Changing it more than once per year, switching plan types, or reinstating a failed plan may cost $25 to $225 depending on your income and the method you use. The IRS will tell you the fee before you proceed.

If I increase my payment, will I pay less interest overall?

Yes. Interest accrues daily on what you owe. The faster you pay, the less interest builds up. If you increase your payment and shorten your plan from five years to three years, you will pay significantly less in total interest, even though your monthly payment is higher.

Can I switch to a payment plan if I already have one?

Yes. You can switch from one plan type to another — for example, from a standard installment agreement to an income-driven plan. Contact the IRS using any of the methods listed above, and they will set up the new plan and terminate the old one.

What if I cannot afford any monthly payment right now?

Request currently not collectible status. This pauses your plan and collection efforts while you recover financially. The IRS will check back periodically to see if your situation has improved. Interest and penalties continue to accrue, but you are not required to make payments during this time.

How long does it take for the IRS to process a plan change?

By phone or online, changes are often processed when ready or within a few business days. By mail, allow four to six weeks. You will receive a new agreement in the mail confirming the changes.
