LT24 Notice: The IRS Needs More Information for Your Payment Plan
By Forrest Baumhover, CFP®, EA · Last verified November 11, 2026
LT24 tells you the IRS received your payment plan proposal but needs more information before it can set up an installment agreement. Finish the request by the date on the notice, or the IRS may move to collect.
If you got this letter
Got an LT24 in the Mail?
You asked the IRS to let you pay over time. The IRS got your request but needs more from you before it can say yes. Your request is not finished yet.
By the date on the notice, either mail a completed payment plan request to the address on the notice or call the number on the notice with your income and expense details in front of you. If you wait past that date, the IRS may start collection.
What LT24 means
The IRS page for this notice says: “We received your payment plan proposal to pay the tax you owe; however, we need more information from you to establish an installment agreement.” An installment agreement is a formal deal to pay the IRS in monthly amounts.
So the IRS has not turned you down, and it has not approved you either. The notice gives you a date to finish the request.
Two ways to finish your payment plan request
The IRS page lists two ways, and you take one of them by the date shown on your notice.
The first is by mail. Complete Form 9465, Installment Agreement Request, and mail it to the address in the “Additional Information” section of your notice.
The second is by phone. Call the number on your notice. The IRS page says to have your income and expense information available when you call, and warns that the IRS “won’t wait on the line while you find your information.” Gather pay stubs, rent or mortgage amounts, utility bills and other monthly costs before you dial.

What happens if you do not respond
The IRS page says that if you don’t respond or don’t pay by the date on your notice, the IRS may pursue enforced collection. It names three examples: filing a Notice of Federal Tax Lien, garnishing your wages or other income, and taking money from your bank accounts.
A Notice of Federal Tax Lien is, in the IRS page’s words, “a public notice to your creditors that the government has a right to your interests in your current assets and any assets you acquire after we file the lien.” The page adds that it can affect your ability to get credit.
One limit applies. If part of what you owe is a shared responsibility payment, the penalty the law set for months without qualifying health coverage (IRC 5000A(b)), the IRS page says the law bars the IRS from using liens or levies to collect that part.
What people mistake LT24 for
Some people read LT24 as a denial of their payment plan. It is not: the IRS page says the IRS needs more information to set up the agreement. Others read it as an approval and start paying under the terms they proposed. Nothing on the IRS page says the IRS accepted those terms, so finish the request by the notice date. A related letter, the LT27, says the IRS still has not received an online payment agreement application and needs your response by the date on the notice, or the account goes back to collections.
And some put LT24 aside because they already applied once. The date on this notice is what counts now.
For practitioners: what to check before the call
Build the financial picture before you call. The IRS page is plain that the IRS will not set up the agreement without income and expense information and will not hold the line while the caller looks for it.
Check whether a simpler route fits. The IRS payment plan page lists several kinds of plans with different setup fees, lower for a direct debit plan, plus fee waivers or reimbursement for low-income individuals. If the client can pay in full instead, the LT24 page suggests paying the balance to stop more penalties and interest. If the client cannot afford any monthly payment, test currently not collectible status, a hold on collection, with the CNC calculator before the call.
Watch the date on the notice. The IRS page ties enforced collection to a missed response or payment date, and lists a Notice of Federal Tax Lien among the first actions.
Common Questions
Is there a fee for a payment plan?
Yes, if the IRS approves your plan, it charges a setup fee. The amount depends on the kind of plan and how you apply. The IRS lists current fees on its payment plan page, which also explains waivers for low-income taxpayers.
What if I don’t have my income and expense information when I call?
The IRS page says the IRS can’t set up an installment agreement without it and won’t wait on the line while you find it. Gather everything before you call.
What if I no longer want a payment plan?
The IRS page says to pay your balance in full to avoid more penalties and interest. You can pay from a bank account with IRS Direct Pay.
What happens if I ignore LT24?
The IRS may pursue enforced collection, including a Notice of Federal Tax Lien or a garnishment of your wages, other income or bank accounts. A lien can affect your ability to get credit.
