For married individuals if the marginal tax rates and the appropriate income brackets for the year 2010 are used, the income of the couple can be divided into the following:
- $16750 taxed at 10% implies a tax of $1675
- $51250 taxed at 15% implies a tax of $7687.5
- $67500 taxed at 25% implies a tax of $16875
The sum of the three values calculated is $1675 + $7687.5 + $16875 = $26237.5
Rounding $26237.5 gives $26238.
The correct answer for the amount of tax liability for the married couple on an income of $135500 is option B or $26238.
