During 2020, I had a 1-hour consulting gig where I earned $425 of 1099-NEC income. I didn't make any est. payment. Sch C was auto generated, but why was my SE tax zero?

I had no other deductions since it was only a 1-hour gig.

The actual calculation of self-employment tax produces a result of zero tax if net self-employment income is $432 or less.

Thanks! That's very helpful!
