The standard deduction is a dollar amount that reduces the amount of income subject to tax. You cannot take the standard deduction if you are claiming itemized deductions.

The amount of standard deduction is based on a taxpayer's filing status. The standard deduction amount can change from year to year depending upon inflation.

Higher Standard Deduction

There is an additional deduction amount for taxpayers age 65 or older, are blind, or both.

The additional amount for age will be allowed if you or your spouse are age 65 or older on the last day of the tax year. The IRS considers you 65 on the day before your birthday.

The additional amount for blindness will be allowed if you or your spouse are totally or partly blind on the last day of the tax year. If you are partly blind, you must get a certified statement from an optometrist or eye doctor declaring you cannot see better than 20/200 vision in one eye (even with eye glasses or contact lenses), or that your field of vision is not more than 20 degrees.

Generally, the amount of the standard deduction is limited to the greater of $950 or your earned income for the year, plus $300. The amount of the standard deduction for a dependent cannot be higher than the regular standard deduction amount.
