These (incredibly small) requirements you list for having a small number of part time employees have been legal obligations for more than 50 years.
So yes, you have to fill out 5 forms, and write 4 checks, every year for withheld taxes.
But none of this qualifies for “it’s sad, it’s getting hard to be a small business”. They’re just things everyone in the US has been legally obligated to do for part time employees for an exceedingly long time.
So I don’t get the tone of this thread.
