If he doesn't get a W2 then he is not an employee and doesn't have SS & Medicare taken out. He is self employed for it. He either will get a 1099NEC or can report it as cash.
To report your self employment income you will fill out schedule C in your personal 1040 tax return and pay SE self employment Tax. You can fill out Schedule C and enter Self Employment Income into Online Deluxe but if you have any expenses you will have to upgrade to Premium version. Or buy any of the Desktop programs. All the Desktop programs have all the same forms, but you will get the most help in the Home & Business version.

Self Employment tax (Scheduled SE) is automatically generated if a person has $400 or more of net profit from self-employment. 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 (FICA). So you get social security credit for it when you retire. It is in addition to any regular income tax you owe on it.
You are paying 15.3% for…..
SS for employer 6.2%
SS for employee 6.2%
Medicare for employer 1.45%
Medicare for employee 1.45%
