Maybe, depending on the amount of other income you received in the year. If you are single, determine whether your benefits are taxable, by adding the following items together:

ADJUSTED GROSS INCOME

+ NONTAXABLE INTEREST
+ ½ YOUR SOCIAL SECURITY BENEFITS
If that value is: Between $25,000 and $34,000, up to 50% of your Social Security benefit is taxable.
Above $34,000, up to 85% of your Social Security benefit is taxable.

If you are married and filing a joint tax return, to determine whether your benefits are taxable, by adding the following items together:

ADJUSTED GROSS INCOME

+ ½ OF YOUR SOCIAL SECURITY BENEFITS
+ ½ OF YOUR SPOUSE’S SOCIAL SECURITY BENEFITS

If that value is: Between $32,000 and $44,000, up to 50% of you and your spouse’s Social Security benefit is taxable.
Above $44,000, up to 85% of you and your spouse’s Social Security benefit is taxable.
