Answer: d. $72,179
Step-by-step explanation:
For couples filing jointly in 2018, their tax rates are as follows:
10% for $0 to $19,050
12% for $19,051 to $77,400
22% for $77,401 to $165,000
24% for $165,001 to $315,000
32% for $315,001 to $400,000
But income tax is progressive, so the tax rate only applies to the amount in that bracket above the basic tax. So their first income of $19050 is taxed at 10% and the next 58350 is taxed at 12% and so on.
For a taxable income of 340000 , the applicable tax is as follows:
19050 at 10% = 1905
58350 at 12% = 7002
87600 at 22% = 19272
150000 at 24% = 36000
25000 at 32% = 8000
1905 + 7002 + 19272 + 36000 + 8000 = $72,179
