What W-9 means

Steam's tax interview asks US payees for a W-9, and Roblox lists a W-9 among the requirements to take part in the Developer Exchange. Non-US payees use a W-8 form instead.^[1],[2]

Why it matters

Missing tax paperwork is a common reason a first payout stalls. Complete it before you reach the minimum balance, and ask a qualified professional about your own situation.^[1],[2]
