Personal income tax dodging is bad as that is where most tax revenue comes from. Taxes should probably be lower on income as well though to discourage tax games and retaining more tax whales (wealthy tax payers). People of all brackets need more money in their pocket for this consumer economy that hasn't really rebounded.

How low is low enough? Pay your damn taxes.
There are lots of taxes beyond income tax. Basically taxes take about .35-.50 out of every dollar earned through income, sales, other taxes. Business expenses for businesses, kids, credits and other things can help bring it down as well as standard deductions but it is still high.
They also don't include self-employment tax (15%) and sales tax (6-10%). Sales tax and self-employment alone are over 20% close to 25% not counted in the article. Property tax can be close to 1% (depends on property), dividend taxes also aren't included (10-15%).
I say corporations won the war, they have the legal teams to keep winning. As a response let small/medium sized businesses compete better by just lowing business taxes to really low levels, or progressive taxing as you grow. Right now the high tax rate only really affects our engine small/medium businesses who provide 50% of GDP, 65+% of jobs and 33% of exports.
The only companies paying taxes are small/medium businesses, the tax system here almost is a competitive advantage to large companies over small/medium. If larger companies aren't going to invest here, get competitive help to the small/medium companies and entrepreneurs that are to challenge them.
