Individuals or their representatives must complete Form 4852 when an employer or payer doesn't issue a Form W-2 or Form 1099-R, or if the issued forms are incorrect.
The form collects personal details (Name, SSN, Address) and requires you to detail wages/taxes from Line 7 (Form W-2) and distribution amounts from Line 8 (Form 1099-R). You must also explain how the amounts on lines 7 and 8 were determined.
The form is used when an individual doesn't receive a missing form in sufficient time to file their income tax return timely. It is filed concurrently with the relevant income tax return.
First, enter your name, SSN, and address on lines 1 through 3. Next, fill in the year (Line 4), employer/payer info (Line 5 & 6). Then, complete Line 7 using W-2 data (like wages/tips or tax withheld) and Line 8 using 1099-R data before signing.
The IRS will challenge claims made using Form 4852 if it is used improperly, potentially leading to accuracy-related penalties of 20% or civil fraud penalties of 75%.
This explains how you determined the amounts listed on line 7 or line 8. Example: State if you estimated the amount, used pay stubs, or used a distribution statement.
