Plain English
If you receive a payment that isn’t a regular paycheck—like a lottery prize or a cash award—you fill out a W‑4S so the payer knows how much tax to keep. The form tells the IRS how many allowances you claim, which changes the withholding amount. It’s a short, one‑page form you sign and give to the payer.
