How a 1099 paystub differs from a W-2 stub
1099 contractors are paid gross — there's no federal income tax, Social Security, or Medicare withholding. The PDF shows your earnings, any deductions you elect to track, and net pay (which equals gross since nothing is withheld).
You're responsible for paying self-employment tax (15.3%) quarterly to the IRS. That's separate from the paystub.
