More than 4.2 million CP53E notices had gone out by May 2026, each one telling an individual taxpayer that the IRS lacked bank details for a refund. The letters follow the end of routine paper refund checks for individuals after September 30, 2025. The count appears in a September 2026 report from the Treasury Inspector General for Tax Administration, which dates the figure to May and credits it to the Government Accountability Office.

What TIGTA report 2026-IE-R015 counts, and the month the count stops
The Treasury Inspector General for Tax Administration report 2026-IE-R015 was issued on September 14, 2026, and lists Nancy A. LaManna as Deputy Inspector General. Its wording on the notices is careful: as of May 2026, according to the Government Accountability Office, the IRS issued more than 4.2 million CP53E notices. That is a cumulative count of letters, not of dollars and not of refunds, and it stops in May. The report offers no later tally, so the number cannot be read as the total of CP53E notices that exist in October 2026.
Other figures in the report carry their own dates. As of March 28, 2026, the IRS reported that nearly 352,000 taxpayers had called the CP53E toll-free line. As of March 30, the IRS had granted 300,537 exceptions for taxpayers. The report also says more than 470,000 taxpayers updated their bank account information using their individual online account. Counts taken weeks apart do not add up to one total, and they are not summed here.
Executive Order 14247 and the September 30, 2025 cutoff
The change traces to Executive Order 14247, signed on March 25, 2025, on modernizing payments to and from America’s bank account. According to the IRS question-and-answer page on the order, last updated January 27, 2026, the IRS generally stopped issuing paper refund checks for individual taxpayers after September 30, 2025. “Generally” is the IRS’s own word. The same page says limited exceptions to electronic methods are made for situations involving hardships and for legal and procedural requirements.
The IRS refunds hub, on its about refunds page updated August 20, 2026, describes paper refund checks as being phased out and gives no date on which the last one will be mailed. The scope is individual refunds. TIGTA reports that only 0.7 percent of business refunds were electronic, so the end of routine paper checks described in these sources is not a description of the business side.
Thirty days to answer the CP53E, then a six-week clock
When banking information is missing from a return, the IRS mails a CP53E notice. The IRS page says the notice asks for a response within 30 days, either to provide banking information or to explain why that information cannot be provided. TIGTA describes the same window as 30 days to update the information in the online account.
The two sources are specific about a missed window. TIGTA writes that if no banking information is provided, the IRS will pause a refund and mail a paper check six weeks from when the return was received. The IRS page says that if there is no response to the notice and there are no other issues with the return, the refund will be released as a paper check after six weeks. On both readings, silence turns the electronic default into a wait rather than a forfeiture, and the paper check is the fallback that an end-of-checks headline leaves out. Neither source says what happens to a response that arrives after day 30, and neither gives a refund amount.
One restriction applies to the response itself. The IRS states that for security reasons its employees cannot take direct deposit information over the phone or in person, so the individual online account is the stated way to supply bank details.
Electronic refunds were already the norm when the notices began
TIGTA puts the electronic share of individual refunds at 85 percent for processing years 2024 and 2025, and at 98 percent by April 2, 2026. Across all federal tax transactions, 654 million of 743 million, or 88 percent, were made electronically. The 98 percent figure comes from the filing season in which the CP53E notices were going out, which places the letters inside the shift to electronic refunds rather than after it. The notices address returns that arrived without usable bank details, the part of the refund stream that had not already gone electronic.
Which dates belong to which page
The mechanism and the volume rest on different documents. The 30-day window and the six-week fallback come from an IRS page last updated January 27, 2026, and from TIGTA’s description of the same process. The 4.2 million figure comes from TIGTA’s September 14 report, whose notice count stops in May 2026. The IRS pages read for this piece give no date on which paper refund checks cease entirely, and they do not say how many CP53E notices have been mailed since May.
The notice asks for bank details, and 5.6 million U.S. households report having no bank account
TIGTA counts 5.6 million American households, 4 percent of all households, as unbanked, and 19 million households, 14 percent, as underbanked. Those are national household totals. They are not the number of CP53E recipients, and the report does not say how many of the 4.2 million notices reached households without an account.
For a taxpayer with no account to name, the notice offers a second kind of answer besides bank details: an explanation of why the information cannot be provided. The IRS lists hardship among the situations that qualify for exceptions, and TIGTA says 300,537 exceptions had been granted as of March 30, 2026. Two clocks run side by side. The 30 days run from the notice, while TIGTA measures the six weeks from when the return was received, so the response window can be closing while the fallback check date is already near.
The official route needs no paid help: bank details go into the IRS online account, and a taxpayer without an account to name can say so to the IRS in answer to the notice, as the IRS page describes. The figures behind that route are TIGTA’s own, dated March for the exceptions and May for the notice count.
Six weeks, one online account and a notice with a thirty-day clock
The CP53E leaves a costly gap between a return that was filed and a refund that moves: a thirty-day response window, a six-week fallback, and a letter that must be matched to the right return before either clock can be read. The news leaves each taxpayer to work out which date applies to a refund the IRS has paused.
