📋 The IRS already has a copy of every 1099 a payer filed with your Social Security number on it. The only question is whether you do.
Every W-2 and 1099 a payer sends you also goes to the government, W-2s through Social Security and 1099s straight to the IRS. After you file, an automated system compares the two piles. When something doesn't line up, an IRS examiner looks at the return, and if the discrepancy holds, a CP2501 or CP2000 notice goes out. The IRS closed about 1 million of those underreporter cases in fiscal 2025.
A CP2000 is not a bill. The IRS doesn't count it as an audit either; it calls these "tax return reviews by mail." It is a proposed change, and you have 30 days from the date on the notice to agree or explain, 60 if you live abroad. Plenty of people pay it reflexively anyway, which is the expensive version of a missing form.
The free fix is your Wage and Income transcript, inside your IRS Individual Online Account. It shows forms such as the W-2, 1098, 1099, and 5498 filed under your number, for this year and the nine before it. It does not show state withholding. New users verify identity first,.
The part the original version of this post got wrong, and several of you pointed out: the transcript is only as complete as what payers have filed. W-2s and 1099-NECs are due by January 31, so those show up in February. Bank and brokerage 1099s can be filed with the IRS as late as March 31, so they often don't appear until April. Corrected brokerage forms and Form 5498 land after the filing deadline.
Your own copies come much sooner. Payers owe you most 1099s by January 31 and brokerage statements by February 15, so you can file on your copies. The transcript is the cross-check, not the source.
For retirees, the two forms that matter most are the SSA-1099 from Social Security and the 1099-R from every pension, IRA, or annuity that paid you. Both arrive in January.
Two things to look for when you compare the transcript to your folder. A form on the transcript you never received: get a copy from the payer. A form with a number that doesn't match yours: that is the payer's error, and you want a corrected 1099 before you file, because the IRS will match against the wrong one. If a payer won't fix a W-2 or 1099-R, the IRS has a process for that too, starting with a call to them after the end of February.
One rule sits above all of this. Income is taxable whether or not anyone sent a 1099. The transcript tells you what the IRS knows. It does not tell you what you owe.
If you get a lot of 1099s, one more limit: the online transcript stops generating at roughly 85 documents, and past that you request it with Form 4506-T.
Do you check your transcript before you file, or has a CP2000 ever shown up in your mailbox?
