Many really small businesses are "S" corps. It makes it significantly easier to comingle personal expenses, etc... with corporate ones and eliminates the double taxation of dividends.
Even for S-Corps there are plenty of real taxes that are dragging hard on small businesses are imposed by the ADA, OSHA, the EPA, the PPACA, etc... The reporting/conformance burden of big government oversight ways far more heavily on them than it does on large corporations.
Who told you that?
I hope you don't face an IRS audit and use that arguement.
Running personal expenses through your subchapter S corp is just as much a violation of IRS regs as in a C corp,.
Having a subchapter S corp allows the shareholder(s) to take distributions from the S crop and not pay Social Security and Medicare taxes.
The IRS has targeted highly profitable subchapter S corps for audit because their compliance models indicate there are high incidences of abuse.

ROFL. I dunno why but the ironic comedic qualities of the bold/underlined statement transports me to front row audience seats at The Comedy Club or NYC's Improv.
