Final answer:
The standard deduction for a married couple is $12,400, assuming they are filing jointly. However, exemptions are no longer available.
Step-by-step explanation:
The standard deduction is a fixed dollar amount that reduces the taxable income and varies depending on the filing status of the taxpayer. For married couples filing jointly or qualifying widow/widower, the standard deduction for the tax year 2014 was $12,400. However, exemptions are no longer available. Previously, exemptions were allowed for each dependent, such as the husband's 82-year-old blind mother, but as of 2018, exemptions have been eliminated.
