DraftKings customers are required to fill out an IRS Form W-9 (W9) following a reportable win. The information provided by the player on Form W-9 (name, social security number, and address) is used by DraftKings to populate IRS Form W-2G. The requirements for reporting and withholding depend on the taxable reporting criteria for the type of gambling, the amount of the gambling winnings, and in some cases the ratio of the winnings to the wager.
In the event your legal name, Social Security Number (SSN), or home address changes please fill out an updated W-9.
If you do not fill out Form W-9 when requested, or if your W-9 cannot be validated with the Internal Revenue Service, then DraftKings is required to remit 24% of the taxable win to the IRS as backup withholding.
