An IRS letter usually asks for something: a document, a correction, a bank detail or a payment. Answering it is the easy part. The harder part is the silence afterward, when weeks pass with no reply and no way to tell whether the response landed or sank.
The question behind that wait is common: I answered an IRS letter weeks ago and heard nothing, is that normal? The IRS’s own guidance says a reply should not be expected right away, and it sets out what to allow for. The sections below separate that waiting period from the response deadline in the notice and from a six-week clock that often gets mistaken for it.

What the IRS says about waiting for a reply
The agency’s Topic No. 651, “Notices – What to do,” carries the one explicit waiting rule: a taxpayer should allow at least 30 days for a reply from the IRS. That is a minimum, and the topic gives no ceiling or promised turnaround beyond it.
The same topic notes that most correspondence can be handled without calling or visiting an IRS office. It also tells taxpayers to keep a copy of all IRS correspondence for their tax records and never to send original documents. Anyone who answered by mail therefore has no reason to expect an answer inside the first month.
Why six weeks is not a reply time
The six-week figure comes from a different part of the IRS. In guidance headed “Direct Deposit Changes for 2026 Could Affect How and When You Get Your Refund,” the Taxpayer Advocate Service describes a CP53E notice, sent when a refund is frozen because direct deposit information is missing or was rejected. If a taxpayer takes no action, the IRS issues a paper check after six weeks.
That clock measures when a paper check goes out, not how long the agency takes to answer a response. A taxpayer who does answer a CP53E by adding bank details in an IRS Online Account is acting inside the notice’s own window, and the page does not promise a reply on any schedule.
The response window sits inside the notice
Waiting is only half the clock. The IRS’s page on understanding a notice or letter says that when the agency asks for a response, the taxpayer should act by the due date, and that replying by the due date is what guarantees appeal rights. A taxpayer who agrees with a notice does not need to reply unless the IRS specifically asks.
For CP53E specifically, the Taxpayer Advocate Service says a taxpayer generally has 30 days to respond. The notice is issued only once, so if a second direct deposit is rejected there is no further chance to update bank information. The 30 days to respond and the 30 days to wait for a reply are different clocks that happen to share a number.
What to check while the reply is pending
The IRS says the CP or LTR number appears in the right corner of the letter, and that certain notices and letters can be found in an online account. Those two details help confirm that a letter is genuine and that the right one was answered.
For a CP53E, the Taxpayer Advocate Service lists an information-only line at 866-325-4066 that gives recorded explanations of the notice and next steps. It does not transfer callers to an agent or accept bank details, and the page says IRS Customer Service cannot add or change banking information. The main IRS line, 800-829-1040, is for people with no bank account who meet waiver criteria and lack Online Account access.
Refund notices have their own clock
Topic No. 651 adds a refund rule. A taxpayer who is due a refund and owes no other tax or debts the IRS must collect should receive it within six weeks of the notice date. The count starts at the date on the notice, not the date the taxpayer responded.
That is the second place the six-week figure appears, and it is why the number circulates so widely. In both IRS pages it describes when a refund or paper check is due after a notice, while the only stated wait for a reply to a response is the 30-day minimum.
Is silence weeks after answering an IRS letter normal for the IRS?
A response sent to the IRS can sit unanswered past the first month without anything being wrong, and a missed response window on a CP53E can turn a direct deposit into a paper check after six weeks. Taxpayers who lose track of which clock is running, the response window or the wait for a reply, tend to chase too early or answer too late.
The IRS Refund Recovery Kit shows why a refund is late, how to read the IRS letters and the steps to trace a refund that never came. It includes a notice decoder, the refund-trace steps using Form 3911, a refund status tracker spreadsheet and the 3-year refund deadline, so the dates on each letter and each response stay in one place.
