Question 1

In part A of the first question given you have been ask to explain which tax rate is of greater significance in measuring the tax effect of Carmen's decision. In order to answer this question, the first thing you may want to note is the definitions of marginal tax rate and average tax rate. After which, you may look at how either rate affects how an individual tax liability is calculated, especially as it relates to charitable contributions (which for taxation purposes are considered as tax deductions which can be subtracted from taxable income before calculating an individual's tax liability). Then you can tell which is of more significant to Carmen's decision.

The marginal tax rate in any country may be defined as, "the tax you pay on your last dollar of income; and more importantly for tax planning, what you'll likely pay on your next dollar earned." Put simply, with marginal tax rates, as income rise, so does the tax rate. In the United States and Canada, tax brackets are used and these define the rates and income levels at which individuals should be taxed. For example, you may find that for an individual who earns $0 to $10,000.00, a Marginal Tax Rate of 20% will apply, whereas for an individual who earns $10,001.00 to $20,000.00 a marginal tax rate of 25% will apply. Hence, the more you earn the more taxes you will pay. Marginal tax rate is usually calculated as follows:

Marginal Tax Rate = Change in Tax Liability / Change in Taxable Income

Marginal tax rate should not be confused though with average tax rate - which is simply the amount of tax you pay divided by your income. It may also be defined as the total amount of income tax a person has paid as a proportion of their total income. Average tax rate is calculated by dividing total tax liability by taxable income. For example, if an individual pays $10,000 in taxes on an income of $100,000, this will result in an average tax rate of $10,000/$100,000, or 10%.

Having looked at the definitions for each, you now need to understand how either rate affects how an individual's tax liability is calculated. To help you with this you may note the following excerpt:

"Everyone wants to find ways to reduce their Federal tax liability. Some people will hire tax professionals and others will spend endless numbers of hours on-line, ...
