The standard deduction of both Bill and Martha can be $2600.
Step-by-step explanation:
There are standard deductions that the people can get from paying taxes for a particular year. The standard deduction can depend and differ from one age group to the other.
If the couple is married and the couple are above the age of sixty five years, then the standard tax deduction from the tax can be increased to an amount of $2600 if they both are not blind. If one of the partners of the couple is blind, then the amount would be different.
