Those loopholes should be closed too. I just don't see an intellectually honest argument that concludes that an $80,000 "bonus" over a $10,000 salary is somehow, through the magic of small business, less taxable than a $90,000 salary.<p>Also: I'm wading into deep water by saying this, but the issue isn't income uncertainty at all, is it? It's not how much you <i>make</i>, it's how much you list as payroll-taxable income. Sure, your salary may be uncertain over the year, but if you end up at $90,000 from your company, your whole income should be liable for FICA just like a BigCo worker's.
