etween 2017 and 2018, a small businessperson's income increased from $200,000 to $220,000. The annual state income taxes that she paid increased from $5 comma 200 to $6 comma 300. What was her marginal state income tax rate in 2018? Did this individual experience proportional, progressive, or regressive taxation? Explain briefly This small businessperson's marginal state income tax rate in 2018 was nothing percent

To determine the marginal tax rate that the businessman paid in 2018, we must obtain the percentage that 6,300 represents in a total of 220,000. This is obtained through a cross multiplication:

220,000 = 100

6,300 = X

(6,300 x 100) / 220,000 = X

2.86 = X

As we can see, the tax rate that this businessman had to pay in 2018 was 2.86% of his income.

Now, in 2017, having obtained a profit of $ 200,000, he paid taxes of $ 5,200:

200,000 = 100

5,200 = X

(5,200 x 100) / 200,000 = X

2.6 = X

Therefore, in 2017 he paid taxes for 2.6% of his earnings.

As we can see, his marginal tax rate increased from 2.6% to 2.86% due to higher profits, which is a situation of progressive taxation.
