Answer 1

I have consturucted the following tables for better understanding:

CASE 1) Individual Filing

	Income	0-20,000 @10%	20,000-50,000 @15%	50,000-90,000 @20%	90,000-200,000 @25%	200,000+ @30%	Total Tax	Average Tax rate
Sam	50,000	2,000	4,500	-	-	-	6,500	13.00%
Joe	75,000	2,000	4,500	5,000	-	-	11,500	15.33%
Daphne	1,50,000	2,000	4,500	8,000	15,000	-	29,500	19.67%
Fred	30,000	2,000	1,500	-	-	-	3,500	11.67%

In this case, the couple's total tax burden is:

	Income	0-20,000 @10%	20,000-50,000 @15%	50,000-90,000 @20%	90,000-200,000 @25%	200,000+ @30%	Total Tax
Sam and Joe	1,25,000	4,000	9,000	5,000	0	0	18,000
Daphne And Fred	1,80,000	4,000	6,000	8,000	15,000	0	33,000

CASE 2) Married-Couple Filing

	Income	0-30,000 @10%	30,000-80,000 @15%	80,000-250,000 @20%	250,000-500,000 @25%	500,000+ @30%	Total Tax	Average Tax rate
Sam and Joe	1,25,000	3,000	7,500	9,000	-	-	19,500	15.60%
Daphne And Fred	1,80,000	3,000	7,500	20,000	-	-	30,500	16.94%

Let me explain the tables. Take Case 1. The column named [0-20,000 @10%] signifies that first $20,000 income will be taxed at 10%. Next column [20,000-50,000 @15%] signifies that the income lying between $20,001 - $50,000 will be taxed at 15%. Note that not the whole income will be taxed at 15% but only the income over and above $20,000 upto $50,000. Similarly, other columns are filled

Average tax rate = [Total Tax/ Total Income]*100

Questions:

1) Joe's average tax rate is 15.33% (From Case 1)

2) In case of individual filing: Joe and Sam pay $18,000 in taxes. In other case, however, they pay $19,500 in taxes. Hence, Joe and Sam jointly pay fewer taxes if they file as an individual. The saving is $1500

3) In case of individual filing: Dephane and Fred pay $33,000 in taxes. In other case, however, they pay $30,500 in taxes. Hence,Dephane and Fred jointly pay fewer taxes if they file as a couple. The saving is $2500
