Answer:
True
Explanation:
The marginal tax rate is defined as the tax rate (in percentage) that is applied to an increase in taxable income. Through the marginal tax rate, a taxpayer can measure the effect of any increase in total taxable income or the effects of any deductions taken.
For example, your current marginal tax rate is 24%, that means that out any additional $100 that your earn, you will be taxed $24. This also applies to deductions, if you donate $100 to a qualifying charity, your taxes will lower by $24.
