I'm sure it's not paid out in one year. A hypothetical $200k nil is probably $200k/number of years of expected participation. I'm sure they have some way to tie nil to a specific schools participation so they don't have to pay nil for an athlete that transfers (although that would be funny).Seems easy enough to get around, assuming the a NIL contract can be written to pay money in out in future years or to a trust.
Not sure why people would think a purported 6-figure NIL deal would be paid in one tax year as a lump sum.
Was Kyle Snyder's gold medal payments put in a trust to maintain his college eligibility?
As for a trust or future years payout; I guess that could be done be I doubt it is being done. I predict the IRS will have a field day with this stuff.
