The 1099-R shows up in your mailbox on February 2nd. You file your tax return on February 10th. Eighteen months later, you get a letter from the IRS saying the retirement distribution you reported doesn’t match their records.
You panic. Did the custodian fail to report it? Did the IRS lose it? Is this going to turn into an audit?
No. The IRS just processes these things on a completely different timeline than you think. Because when you get your copy and when the IRS actually cross-checks everything are separated by over a year.
The deadline for custodians to send 1099-Rs to account holders is February 2nd, 2026. That’s the date you’re probably familiar with. The envelope shows up in early February. You open it. You see the distribution amount. You enter it on your tax return.
But the custodian doesn’t file that same form with the IRS on February 2nd. They file it later. Sometimes two months later.
The IRS deadline for custodians to electronically file 1099-Rs is March 31st, 2026. Not February 2nd. If the custodian files on paper instead of electronically, the deadline is earlier at March 2nd, but most large custodians file electronically and use the full window through the end of March.
So if you took a retirement distribution in December 2025, got your 1099-R on February 2nd, 2026, and filed your return on February 12th, the IRS has not received anything from your custodian yet. The form is still sitting at the custodian waiting to be transmitted. You filed your return before the IRS even knew the distribution existed.
This creates a timing gap. But not the one most people think.
At Charles Schwab, I took calls from people who filed early and assumed the IRS would reject their return immediately because the 1099-R data wasn’t in the system yet. That’s not what happens. The IRS doesn’t stop your return at the gate and demand to see proof. They process the return. They usually issue the refund. They trust what you reported.
The cross-checking comes later. Much later.
The IRS Information Returns Program runs a massive automated matching operation, but it doesn’t happen in February or March or even June. It happens twelve to eighteen months after the filing deadline. That’s when the computer systematically compares every 1099-R filed by every custodian against every tax return filed by every taxpayer. If the numbers don’t match, the system generates a CP2000 notice.
So if you filed your 2025 return in February 2026 and reported a distribution that doesn’t match what the custodian eventually filed, you’re not getting a letter in April 2026. You’re getting it in mid-2027. A year and a half later. By then, you’ve completely forgotten the details.
Here’s what happens behind the scenes. Schwab (or your custodian) issues the 1099-R to the client by February 2nd. That’s required. But the custodian doesn’t file the form with the IRS until closer to March 31st. They batch all the forms together and transmit them electronically in one large file. The IRS receives the file, processes it, and loads the data into their master database. That database sits there accumulating data from every custodian in the country. Then, over a year later, the IRS runs the matching program. That’s when discrepancies surface.
People assume the IRS operates in real time. That if a transaction happened in December and the form was issued in February, the IRS is cross-checking it by March. They’re not. The IRS receives information on a delay and processes it in massive annual batches. Nothing happens instantly.
If you file your return before the custodian files the 1099-R, the IRS doesn’t freeze your refund waiting for confirmation. They process the return based on what you reported. If you said you had a $50,000 distribution, they trust you and move forward. The refund gets issued. The return gets accepted.
The verification happens over a year later when the automated system runs its comparison. If the custodian filed a 1099-R showing $50,000 and you reported $50,000, everything matches. No notice. If the custodian filed $60,000 and you reported $50,000, the system flags the discrepancy and generates a CP2000 notice asking you to explain the $10,000 difference.
By the time that notice arrives, it’s summer 2027. You filed the return in February 2026. You’ve moved on. You don’t remember the details. You have to dig out the paperwork from eighteen months ago and figure out where the discrepancy came from.
The way to avoid this is not to wait until the custodian files the 1099-R with the IRS. Waiting until April to file your return doesn’t help. The issue isn’t the timing gap between when you file and when the custodian files. The issue is whether the numbers on your return match the numbers the custodian eventually reports. If they match, the eighteen-month delay doesn’t matter. If they don’t, you’re getting a notice regardless of when you filed.
The same delayed matching applies to other retirement forms. Form 5498, which reports IRA contributions and fair market values, has an even later deadline. Custodians don’t file Form 5498 with the IRS until June 1st, 2026. If you made a prior-year IRA contribution in March 2026 and filed your return in April claiming the deduction, the IRS has no record of that contribution when they process your return. The Form 5498 showing the contribution won’t be filed for another two months.
Does that mean the IRS will reject your return? No. The IRS processes the return and issues the refund. They’ll verify the contribution against the Form 5498 data over a year later when they run their matching program. If the numbers match, nothing happens. If they don’t, you get a notice in 2027 asking you to explain the discrepancy.
This is also why you can’t call the IRS in March 2026 and ask them to confirm they received your 1099-R. Even if the custodian filed it on March 31st, the IRS hasn’t loaded it into the cross-checking system yet. The representative on the phone will tell you they have no record of it. That doesn’t mean the form wasn’t filed. It means it hasn’t been matched yet.
If the custodian files an amended or corrected 1099-R after the original was submitted, the IRS gets that too. Sometimes months later. The amended form overwrites the original in the IRS system. If you filed your return based on the original 1099-R and the custodian later corrected it, the IRS cross-checking system will see a mismatch between your return and the corrected form eighteen months after you filed. That’s when you get a CP2000 notice asking you to explain the difference.
The notice doesn’t say the custodian filed a correction. It just says the IRS records don’t match your return. You have to figure out that the custodian amended the form. You have to track down what changed. You have to respond to the notice with documentation showing why your original return was correct based on the information you had at the time.
The date you receive your 1099-R and the date the IRS receives your 1099-R are not the same. One is early February. The other is late March. But that’s not the date that matters. The date that matters is when the IRS runs their automated matching program. That’s twelve to eighteen months after you file. If the numbers match, the timing gap is irrelevant. If they don’t, you’re getting a notice in 2027 regardless of whether you filed in February 2026 or April 2026.
Filing early doesn’t create the problem. Filing with numbers that don’t match what the custodian eventually reports creates the problem. The mismatch notice just takes over a year to arrive.
