The E-Printview tool can provide a likely preview of the information, but it’s not guaranteed to be 100% accurate. Timing discrepancies, errors, or pending updates can affect what is shown. Therefore, it’s best practice to wait until you obtain your employer issued official W-2 for the most accurate reporting.
It is also recommended that you match the auto-filled information to the actual W-2 when you receive it. The IRS matches the information reported on your W-2 to ensure consistency, so it's best to compare the auto-filled information with your official W-2. If you can't access your W-2, contact your employer directly to request it. Alternatively, you can check your IRS account online to see if the W-2 has been submitted and access a transcript. If necessary, you can file Form 4852 as a substitute for the W-2, but this could take additional time to process.
