I thought you still had to pay in Social Security at any age,
there is an exception for
The tax benefits of employing your child
You can shelter yourself from paying most—if not all—taxes on the wages you’re paying your children if your business is either a 1) sole proprietorship, 2) a partnership where both partners are spouses, or 3) an LLC that has elected to be treated as either #1 or #2. Specifically, if you employ your child who is under 18 years old, their wages are exempt from:
Social Security tax
Medicare tax
Federal unemployment (FUTA) tax
Once they turn 18, you’ll have to start paying Social Security and Medicare, but they remain exempt from FUTA tax until they turn 21.
