For 2013, the standard deductions are $12,200 for married couples filing jointly, $6,100 for married couples filing separately and singles, and $8,950 for heads of household. Are you someone's dependent?
Choose 'no' if no one can claim you or your spouse as a dependent. Choose 'yes' if someone can claim you as a dependent. Choose 'both you and your spouse if you both are dependents. (You are a dependent if someone supports you and can claim a dependency exemption for you.) Number of additional dependents
A dependent is someone you support and for whom you can claim a dependency exemption. In 2013, each dependent you claim entitles you to receive a $3,900 reduction in your taxable income (see exemptions below). You may also receive a tax credit of up to $1,000 for each dependent child under the age of 17. The credit is, however, phased out at higher incomes. Itemized deductions
This is the total of your itemized deductions that you can include on schedule A of your Federal income taxes. For most people this includes state income taxes paid for the year, interest on a mortgage and any charitable contributions. Other itemized deductions include certain investment expenses, medical expenses exceeding 7.5% of your adjusted gross income, and some moving expenses.
Your standard deduction will be automatically calculated for you based on the filing status and number of dependents you enter. If the number you enter here is lower, your standard deduction will be used to determine your average tax rate.
