re: Anyone know the TAX of NIL

If no entity is set up, the 1099 income would be reported on a Schedule C of their individual income tax return, form 1040.

On an assumed NIL payment of $100,000 subject to a 10% agency/agent fee filing single with no dependents:

The resulting realized $90,000 in income would be reduced by $6,358 as the deductible portion of Self-Employment taxes and $12,500 in the standard deduction and $14,218 in QBI deduction.

Leaving $56,874 in taxable income. With federal income tax of $8,261 and self-employment tax of $12,716 for a total tax bill of $20,977 to uncle sam. Please note that state income and self-employment taxes are not included in these figures. Using a conservative 5% that is an approx. $4,250 state tax bill.

To recap

$100,000 NIL payment
(10,000) agent fee
(20,977) federal income and self employment taxes
(4,250) state income taxes
_______
$64,773 after tax income

ETA: May not qualify for the QBI deduction due to the nature of the "business" and federal income taxes would be due on the $14,218. Used a quick online calculator, not actual tax prep software for the above illustration.
