• Problem 50: Xavier and his wife Maria have total W-2 income of $93,102. They will file their tax return as married filing jointly. They had a total of $7,910 withheld from their paychecks for federal income tax. Using the tax tables, determine the amount of refund or additional tax due upon filing their tax return. Indicate whether the amount is a refund or additional tax.

The United States tax system primarily operates under a progressive tax rate structure, where tax rates increase as the taxable income increases. However, in this exercise, various calculations are performed based on a hypothetical proportional tax rate structure as well as utilizing the existing tax tables and rate schedules for different taxpayers in the year 2017.

Problem 37: Calculation under a Proportional Tax Rate Structure

Assuming the federal tax system was changed to a proportional tax rate of 17%, the tax liability for 2017 would be calculated by multiplying the taxable income of all taxpayers by this rate. According to IRS statistics, as of 2017, the total taxable income of all taxpayers was approximately $9.57 trillion. Thus, under a 17% rate, the total tax liability would be:

Tax Liability = Total Taxable Income x Tax Rate

Tax Liability = $9,570,000,000,000 x 0.17 = $1,628,900,000,000.

When compared to the actual federal tax revenue, which was approximately $3.32 trillion in 2017, the differences highlight the implications of altering the tax structure significantly. The effective tax system raised nearly double what the proportional system would have garnered, showcasing the impact of graduated tax brackets which typically tax higher earners at higher rates.

Problem 41: Cameron's Tax Liability

Cameron's taxable income is $88,806. The tax liability can be determined using the tax tables, which indicate that his total tax liability at this income level is approximately $15,309. However, if we use the tax rate schedule for 2017, which includes multiple tax brackets, his calculated tax would also yield a marginal tax rate of 24% due to being within that tax bracket. The key difference arises because the tax tables provide a standardized amount, while the tax rate schedule calculates based on the applicable rates for different portions of his income. This usually results in slightly higher actual liabilities using the bracket method, reflecting the progressive nature of taxes.

Problem 43: Tax Liability, Marginal & Average Tax Rates

a. Single taxpayer, taxable income of $38,862:

From the tax tables, the tax liability is approximately $5,297. The marginal tax rate is 12% (as income is in that bracket), and the average tax rate is:

Average Tax Rate = (Tax Liability / Taxable Income) 100 = ($5,297 / $38,862) 100 = 13.62%.

b. Single taxpayer, taxable income of $89,889:

The tax liability from the tables is $15,309, with a marginal tax rate of 24%. The average tax rate is calculated as follows:

Average Tax Rate = ($15,309 / $89,889) * 100 = 17.03%.

Problem 45: Tax Liability, Marginal & Average Tax Rates for Married Taxpayers

a. Married taxpayers, taxable income of $38,862:

Here, the tax liability using the tax tables is approximately $4,297. The marginal tax rate is 12%, and consequently, the average tax rate is given by:

Average Tax Rate = ($4,297 / $38,862) * 100 = 11.06%.

b. Single taxpayer, taxable income of $61,229:

The liability determined from the tables is around $10,305, leading to a marginal tax rate of 22%, resulting in an average tax rate calculated as:

Average Tax Rate = ($10,305 / $61,229) * 100 = 16.83%.

Problem 50: Xavier and Maria Tax Calculation

Xavier and Maria's total W-2 income is $93,102. Upon filing as married filing jointly, their tax liability is determined via tax tables to be approximately $14,840. With $7,910 withheld, this leads to calculations for their refund or additional tax:

Refund/Additional Tax = Amount Withheld - Tax Liability = $7,910 - $14,840 = -$6,930. Therefore, they owe an additional tax of $6,930 when filing their return.

Conclusion

In summary, completing these problems provides insights into how the tax system works under both a proportional scenario and the actual tax tables. This exercise demonstrates the importance of understanding tax structures to assess liabilities accurately and project financial outcomes as tax return preparation approaches.
