Why am I being asked to submit a Form W-9?

The IRS mandates that 1099-MISC forms must be issued to individuals who were paid over $2,000 in prizes, awards, and other income payments. Non-transactional Rewards fall into this category, so users who earn more than $2,000 in non-transactional Rewards must submit a Form W-9 so that a 1099-MISC can be issued to you.
