Tax Forms

If the recipient is a statutory employee, wage income and expenses are reportable on Schedule C. Earnings are not subject to income tax withholding but are subject to SS and Medicare taxes.
Covered by a retirement plan box being X'd means the recipient is subject to the phase-out rules for IRA deductions.
Income reportable as 3rd party sick pay has this checkbox X'd.

If, even after nudging from the IRS, your employer doesn't send you a replacement W-2 in time for you to file your return, you may file using Form 4852 in place of your missing wage statement.
After you complete the form, attach it to your tax return in place of your absent W-2. A copy of Form 4852 also should satisfy your state tax collector for those returns.
Using Form 4852 instead of an original W-2 may delay your refund while the IRS verifies the information you provided.
In cases where an employer has filed for bankruptcy or ceased operations, the IRS suggests you send a copy of Form 4852 to your local Social Security Administration office.
This should ensure that you get proper credit for the Social Security and Medicare taxes you paid so that your checks will be correct when it comes time to collect these benefits.

W-2 forms should be furnished to your employees by January 31. It is your responsibility as an employer to file Forms W-2 with the Social Security Administration (SSA) for your employees which will show the wages paid and taxes withheld for the year.
You must send Copy A to the SSA with Form W-3 by February 28.
Form W-3 is a summary form that shows the total of all W-2's being sent. Go to the IRS website or get Publication 15, Circular E, Employer's Tax Guide or Forms and publications can be requested by calling 1-800-829-3676.

If you cannot get a duplicate W-2 from your employer, your local CPA can use Form 4852, substitute W-2 to reconstruct your salary and use it for your tax return.
A copy of Form 4852 should be sent to the Social Security Administration to help ensure proper credit of the Social Security taxes.
