Nope actually you proved my main figures. 1.5 trillion tax revenue for the top 25% of wage earners and 400 billion for the rest; almost double the revenues. Debt would be paid in 30 years. You should actually run the numbers before you decide I am either being too strict or not strict enough. actually the cut off is 67k not 50k. If you take in net worth into the equation you could come up with 400 billion easy. The only thing it doesnt take into account is people with money and assets who use the system and don't pay for it because they are not earning anything.
I took 25% of 5.7 trillion and rounded up. 10% tax for 66k and down with 15k deduction; except those who have decent net worth wouldn't get any deduction; 400 billion easy. If they wanted a deduction they would have to report assets similar to what you report in a bankruptcy. Give a 200$ credit to people who don't have the assets to afford the paperwork. Seems like the debt would be paid and the economy would go though the roof since there would be money to build infrastructure.
You clearly do not realise how marginal tax rates work. I will attempt to educate you.
When you say, above $50,000 - 25%, below $50,000 10% I think that you are proposing that if you earn over $50,000 then all your income is taxed at 25%. You could do this, but you'd find that people would either earn $49,999 or less or more than $57,500 because in between these two figures you'd actually be worse off. You've also forgotten your proposal to pool allowances so that two earners in a household could total up to $100,000 before paying at the higher rate (unless you are going to change this).
Now if your proposal is to tax at 25% all income for people who earn more than $50,000 then what you are proposing is a 60% tax raise for the middle classes and no significant change for the truly wealthy.
But lets' run the maths......
Example 1: $15k deduction, graduated tax.
I earn $70,000
I pay no tax on the first $15,000
I pay tax at 10% on the next $50,000 = $5,000
I pay tax at 25% on the remaining $5,000 = $1,250
Total tax = $6,250 - under 10%, significantly less than now
Example 2: $15k deduction, no graduation.
I earn $70,000
I pay no tax on the first $15,000
I pay tax at 25% on the remaining $55,000 = $13,750
Total tax = $13,750 - around 20%, a 30% increase (meanwhile Mr Moneybags who earns $millions has his tax bill increase by less than 10%)
Example 3: No deduction, no graduation.
I earn $70,000
I pay tax at 25% on all the $70,000 = $17,500
Total tax = $17,500 - 25%, a 60% increase (meanwhile Mr Moneybags who earns $millions has his tax bill increase by less than 10%)
So either the tax take will be lower (if a graduated tax is applied) or the tax take will be higher but the tax burden will be shifted unfairly to the middle classes whereas the truly well off have a tiny increase in their taxes.
The consequence of this huge increase in taxation would be that the middle classes, the ones who are responsible for a lot of the discretionary spending, would have to trim their budgets significantly elsewhere. There would be a significant decrease in spending, the economy would take a nosedive.
The same problem applies at the lower income levels:
Example 4: $15k deduction
I earn $40,000
I pay no tax on the first $15,000
I pay tax at 10% on the remaining $25,000 = $2,500
Total tax = $2,500 - around 6%, half my current taxation rate of 13%
Example 5: No deduction, no graduation.
I earn $40,000
I pay tax at 10% on all the $40,000 = $4,000
Total tax = $40,000 - 10%, still significantly lower
So the people in the range $30,000 --> $65,000 will end up paying significantly less tax whether they qualify for the deduction or not. How does that increase your tax take ?
As an aside....
The $200 wouldn't even come close to the fees required to determine net worth. Bankruptcy audits costs thousands, tens of thousands of dollars. You'd be establishing a whole new, non-value added industry of hiding net worth and an intrusive bureaucracy of attempting to disclose net worth. Basing the deductions on net worth would be impossible to implement and political suicide (farmers who are cash poor but asset rich would be a good example of a group who would be unfairly punished by your scheme.
