Like 10% of what ever u make? Straight Across? No ways around just straight?

Probably lower for lower earners. Something like 5% for under $30,000, then 7% up to $100,000, the 10% up to $250,000, then 15% above that.
You would also have to lower the corporate tax rate but make it flat as well but no more than 20% and cut all deductions/government subsidies
