Do i need to file as self employed and just do design very part time

Yes, the IRS requires that you file as self-employed.  Sole proprietor, independent contractor, consultant and freelancer are all terms used to describe self-employed workers. Whether you do it full-time or very part-time—if you’re an independent worker like a designer, ride-share driver (Uber), tutor, or babysitter—you’re self-employed.

You may not think of yourself as running a business, but Per the IRS, you’re considered self-employed if you engage in business-like activities.

Three key factors that generally define an activity as a business:

• You intend to make a profit (even if you operate at a loss).
• Your activities are regular.
• You make efforts to sustain or grow your business.

Situations where you wouldn't be considered self-employed:

• You mowed your elderly neighbor's lawn all summer, and he gave you money as a token of his appreciation. (You didn't intend to make a profit.)
• You were paid to tutor a friend's child, but you’re not going to do it again. (Your activities are not regular.)
• You draw for fun, and your friend paid you to create a poster for a birthday party. (You're not making efforts to sustain or grow a business.)

When you’re self-employed, you’re likely to receive a 1099-MISC or a 1099-K. Even if you don’t receive these forms, you still need to report all your income from self-employment.

Additionally, you do have to pay for your return prior to printing it for review.
