Family Work

I made a good income at my full time self employment.

I also made about $400 while doing the same type of work for my family, paid by check. I was not doing this work in my official self employed capacity, no invoices, business cards, advertising, logos, business emails or other business-like papers or procedures were used. All of the work was done in a family chore like way, using personal phone numbers, personal email addresses and communications. Do I have to report my Family Work income? Thank you.
