Pros: 
1. Simplicity in filing taxes - no need to calculate deductions or exemptions, which can be complicated.
2. Lower administrative costs as there is less paperwork involved.
3. Allows for more efficient collection of taxes by the government.
4. Can simplify the process of determining taxable income.
5. Can provide greater financial security by ensuring that everyone pays their fair share.

Cons:
1. It may discourage people from taking advantage of certain deductions or credits that they might qualify for if they had to pay taxes on them.
2. People who make higher incomes will have to pay a larger percentage of their total income than those with lower incomes.
3. May lead to increased inequality as those making higher incomes pay a larger proportion of their income in taxes.
4. Those earning below the minimum wage would not benefit from any earned income tax credit.
