No you don’t report his income on your tax return. He has to file a return for the 1099NEC. 1099NEC is self employment income and you HAVE to file it on Schedule C and pay self employment tax on it. The SE tax is to pay both the Social Security and Medicare tax that wasn't taken out like on a W2 job.
You will pay Self Employment tax (Scheduled SE) on a Net Profit of $400 or more on Schedule C in addition to regular income tax on it. You pay 15.3% SE tax on 92.35% of your Net Profit (If it is greater than $400). The 15.3% self employed SE Tax is to pay both the employer part and employee part of Social Security and Medicare. So you get social security credit for it when you retire.
Be sure on his return he checks the box that says he can be claimed on someone else’s return.
