You can change your payment plan online, by phone, or by mail — the fastest route depends on what you want to change
If you have an active IRS payment plan and need to modify it — lower the monthly payment, extend the term, switch to a different plan type, or cancel it entirely — you have three main paths. The IRS Online Payment Agreement tool lets you make certain changes yourself in minutes without calling. The IRS automated phone line (800-829-1040) handles modifications during business hours. Mailing a written request works but takes weeks. Which one you use depends on whether your change is simple (payment amount) or complex (plan type), and whether you want to move fast.
The method you choose also depends on what information you have available and how quickly you need the change to take effect. Online changes happen within one business day. Phone calls can be handled the same day but involve wait times. Mail takes 30 to 45 days but creates a paper record and works if you lack internet access.
Key Takeaways
- The IRS Online Payment Agreement tool lets you lower your monthly payment or extend your plan term without speaking to anyone, and changes take effect within one business day.
- You cannot switch from one plan type to another (for example, from a short-term to an installment agreement) online — that requires a phone call or written request.
- Calling 800-829-1040 during business hours (Monday through Friday, 7 a.m. to 7 p.m. your local time) connects you to a representative who can handle any change, though wait times often exceed 30 minutes.
- Canceling your plan stops the automatic payments but does not erase what you owe — you will still be liable for the full tax debt plus any penalties and interest that continue to accrue.
- If you miss a payment on your modified plan, the IRS may terminate the agreement and pursue collection action, so confirm the new terms in writing before your first payment is due.
Changing your payment amount or plan length online
The IRS Online Payment Agreement tool is the fastest option if you want to lower your monthly payment or add months to your plan. Go to irs.gov/payments, select "Manage Your Payment Plan," and sign in with your IRS username or ID.me credentials. You will need your Social Security Number or Individual Taxpayer Identification Number, the tax year of the debt, and your current payment plan number (found on your IRS notice or payment coupon).
Once logged in, you can view your current payment amount and remaining term, then request a new monthly payment or extend the plan by up to 120 months total. The system will show you the new payoff date and total interest cost before you confirm. Changes made before 11:59 p.m. Eastern Time take effect the next business day. You will receive a confirmation email and can print or save a copy of your modified agreement.
This tool works only for installment agreements (monthly payments spread over time). It does not work for short-term extensions, partial payment plans, or if you owe more than one tax year. If your situation is more complex, use the phone line or mail instead.
Calling the IRS to change your plan type or handle complications
Call 800-829-1040 if you want to switch plan types (for example, from an installment agreement to a short-term extension), if you owe multiple tax years, or if you need to discuss hardship. The line is open Monday through Friday, 7 a.m. to 7 p.m. your local time. Have your Social Security Number, the tax year(s) you owe, your current payment plan number, and a list of changes you want to make ready before you call.
Wait times are often 30 to 60 minutes, especially during tax season (January through April) and in the weeks after the April 15 filing deadline. Call early in the morning or late in the week to reduce your wait. The representative can modify your payment amount, extend your term, cancel your plan, or move you to a different plan type. They will explain the new terms, confirm your new payment date, and send you a written notice within 30 days.
If you cannot reach a representative after waiting, ask to leave a callback request. The IRS will call you back within 24 hours during business hours, though this option is not always offered. Do not hang up and call back immediately — each call restarts your wait time.
Requesting changes by mail
You can request a plan change in writing by sending a letter to the IRS address shown on your most recent notice. Include your name, Social Security Number, the tax year(s) you owe, your current payment plan number, and a clear description of what you want to change (for example, "Request to lower monthly payment from $500 to $300" or "Request to extend plan term by 24 months").
Mail your letter to the IRS address printed on your notice or payment coupon. Keep a copy for your records. The IRS typically responds within 30 to 45 days, though processing can take longer during peak periods. You will receive a written notice confirming whether your request was approved and what your new terms are. Until you receive that notice, continue making your current payment to avoid default.
This method is slower than calling or using the online tool, but it creates a paper trail and works if you do not have internet access or prefer written communication. If you do not hear back within 60 days, call 800-829-1040 to confirm the IRS received your letter.
What happens when you cancel your payment plan
Canceling your plan stops the automatic monthly payments but does not forgive the debt. You will still owe the full amount you originally agreed to pay, plus any penalties and interest that continue to accrue. The IRS will send you a notice confirming the cancellation and may begin collection action — wage garnishment, bank levy, or property lien — if you do not pay the balance in full.
Cancel your plan only if you can pay the full balance immediately or if you are pursuing another option like an Offer in Compromise (a settlement for less than you owe) or Currently Not Collectible status (a temporary pause on collection while you face hardship). If you cancel by mistake or change your mind, call 800-829-1040 to reinstate your plan, though the IRS may require you to reapply and may impose a new setup fee.
Fees and penalties for changing your plan
Modifying an existing plan online or by phone does not cost extra — there is no fee to lower your payment, extend your term, or cancel. However, if you default on your modified plan (miss a payment), the IRS may terminate the agreement and charge a default fee of $225 (or $25 if your income is below 250 percent of the federal poverty line). You will also owe any penalties and interest that have accumulated.
If you want to set up a brand new plan after canceling an old one, the IRS charges a setup fee: $31 to $225 depending on how you set it up (online is cheaper than by phone or mail). This is a one-time charge added to your debt. Modifying your current plan avoids this fee entirely.
Confirming your changes in writing
After you make any change — online, by phone, or by mail — request written confirmation of your new terms. If you changed online, print or save your confirmation email. If you called, ask the representative to mail you a notice and note the date and representative's name. If you mailed a request, keep a copy and the postal receipt.
Before your first payment under the new plan is due, verify that the IRS processed your change correctly. Log into your IRS account at irs.gov/account to check your payment plan details, or call 800-829-1040 to confirm. If something is wrong — the payment amount is still the old amount, or the term was not extended — contact the IRS immediately to correct it. Do not assume the change went through if you have not seen written proof.
Frequently Asked Questions
Can I lower my payment if I am facing financial hardship?
Yes. If your current payment is too high, you can request a lower amount through the online tool, by phone, or by mail. The IRS will calculate a new payment based on what you can afford, though this may extend your payoff date and increase the total interest you pay. If you are in severe hardship, ask about Currently Not Collectible status, which pauses collection temporarily while you recover.
What if I want to pay off my plan early?
You can pay more than your monthly payment at any time without penalty. Send extra payments to the address on your payment coupon or make them online at irs.gov/payments. The extra amount goes toward your principal, reducing the total interest and shortening your payoff date. You do not need IRS permission to pay early.
Will changing my plan affect my credit score?
Modifying an existing payment plan does not report to credit bureaus or affect your score. However, if you default on your modified plan and the IRS files a tax lien, that lien will appear on your credit report and harm your score. Staying current on your new payment protects your credit.
How long does it take for a plan change to show up in my IRS account?
Online changes take effect the next business day and should appear in your IRS account within 24 hours. Phone and mail requests take 30 to 45 days to process. Until you see the change in your account, continue making your current payment to avoid default.
Can I change my plan if I am behind on payments?
If you have missed one or two payments, you can still modify your plan by calling 800-829-1040 — the representative may ask you to catch up on missed payments first. If you have missed three or more payments, your plan may already be in default and the IRS may have terminated it. Call immediately to find out your status and discuss your options.
