If you can't get your Form 1099 or W-2 from your employer you can report it to the IRS. An IRS representative will contact a late payer for you. Call the IRS at 800-829-1040 to start the ball rolling by reporting your late 1099.
You can also file your tax return without the actual 1099, as though you have one. This should be sufficient proof of income as needed.
