Ironically, corporate taxes these days generates less than 20% of the fiscal revenues for the government. Generally, 1040 individual taxes still make up the bulk of the taxes paid.
In addition, more than 35% of all taxpayers pay zero tax or pay no tax and get refunds. This number is constantly changing, especially recently with the economy. I've seen it go as high as 60%.
Lastly, when the government talks about corporate tax breaks and etc. Honestly, they barely matter anymore because we've essentially marginalized the revenue generated from corporations and businesses already. So, the amount of revenue and savings potential in the greater scheme of things is almost non-consequential.
