You can eliminate state income taxes. You can delay paying your taxes for another year . With the IRS, the more you make, the higher percentage of your income goes to the government.
Many states also impose a personal income tax.
You may also be paying FUTA, workers compensation, transportation taxes and so on. Then there are also capital gains taxes. You pay those on your gross capital gains and there are few deductions. A corporation pays no social security taxes, no Medicare and no workers compensation on its own income. This is just on federal income tax alone.
