We do not have the "Tax Rate Schedule formulas".

To find the taxes for each scenario using the appropriate Tax Rate Schedule formulas, we need to know the tax brackets and rates for each filing status.

Assuming we are using the 2021 tax brackets for individuals in the United States, the tax rates are as follows:

Single:
- 10% on income up to $9,950
- 12% on income between $9,951 and $40,525
- 22% on income between $40,526 and $86,375
- 24% on income between $86,376 and $164,925
- 32% on income between $164,926 and $209,425
- 35% on income between $209,426 and $523,600
- 37% on income above $523,600

Married, filing jointly:
- 10% on income up to $19,900
- 12% on income between $19,901 and $81,050
- 22% on income between $81,051 and $172,750
- 24% on income between $172,751 and $329,850
- 32% on income between $329,851 and $418,850
- 35% on income between $418,851 and $628,300
- 37% on income above $628,300

Head of Household:
- 10% on income up to $14,200
- 12% on income between $14,201 and $54,200
- 22% on income between $54,201 and $86,350
- 24% on income between $86,351 and $164,900
- 32% on income between $164,901 and $209,400
- 35% on income between $209,401 and $523,600
- 37% on income above $523,600

Married, filing separately:
- The tax brackets and rates are usually the same as for singles, but with half the income thresholds.

Using these tax rates and brackets, let's calculate the taxes for each scenario:

1. Single - $168,000
The tax bracket for income $168,000 falls into is:
- $168,000 is between $86,376 and $164,925, so it falls into the 24% tax bracket.
To calculate the tax:
- The portion of income taxed at 24% is ($168,000 - $86.375) = $81,625.
- The tax amount for this portion is $81,625 * 24% = $19,590.
Therefore, the taxes for a single individual with an income of $168,000 is $19,590.

Similarly, you can use the above method to calculate the taxes for the remaining scenarios by identifying the income bracket and applying the appropriate tax rates.
