If you choose not to itemize your deductions, you can go for the standard option, which is based on your filing status. For 2014, the standard deduction is as follows:
Single taxpayers - $6,200
Married Filing Jointly - $12,200
Head of Household - $9,100
Married Filing Separately - $6,200
Qualifying Widow(er) - $12,400
If you are 65 years of age, or you are legally blind, the standard deduction rate is higher. Also, if you are able to be claimed as a dependent by someone, your deduction is limited.
