Fair? Tax Proposal

I suppose "fair" is a bit in the eye of the beholder so what I mean by it is that the rules are exactly the same for everyone. We can quibble about any of the numbers I use (mostly from the IRS) but they can be adjusted as necessary to get a more accurate result, what its important is the general construct of the tax system being proposed. As in any undertaking, there must be initial assumptions made about the parameters being used. For this I am assuming 153 million US taxpayers who earn collectively $14.7 trillion plus corporate profits of $12 trillion every year. Also, assuming that the feds spend $7 trillion each year and a total deficit of $37 trillion. Other assumptions can be figured as necessary.. 

The first part of the proposal is that since "corporations are people" they should pay taxes at the same rate as people. As of 2023, about 85% of the federal revenues were income and payroll taxes, so it seems obvious to me that they currently do not. The second part is that there should be no deductions, period. If the federal government sees something deserving of money, they can fund it directly. The final part is that everyone will pay taxes at the same rate.

Nobody would pay any federal tax on the first $20,000 they make in a year, making about $3 trillion exempt from taxation, and I can assume about 36 million people will end up owing nothing. The next $20,000 ($20,000-$40,000) would be taxed at 1%. If there are 35 million more people that will owe no further tax after this, we will have collected about $20 billion on the first $6 trillion in nationwide earnings. From $40,000-$60,000 taxes would be at 2 1/2%. From $60,000-$100,000 taxes would be 5%. From $100,000-$200,000, taxes would be at 10%. From $200,000-$500,000 taxes would be at 20%. From $500,000-$1,000,000 taxes would be at 33%. Anything over $1,000,000 would be taxed at 50%, this category affecting about 500,000 filers and contributing about a trillion dollars to the treasury. All told, income tax would come to around $4 trillion, not too far from what it is now. However, when you take into account corporate taxes, they would pay only a little less than half of the $12 trillion they made in profits if they paid at the same rate as everyone else. That means the treasury would take in around $10 trillion a year. This would pay the federal deficit off in around 10-15 years with no cuts in government spending (except no deductions would automatically cut the budget a fair amount) and we then could then give tax breaks to the wealthy with no ill effects.
