Normally you may exclude up to $250,000 ($500,000 married filing jointly) on a home sale. The rule is that must have lived in the home for at least 2 years. If your move is based on a job change, relocating you more than 50 miles, you may still exclude the gain, but the maximum is reduced.
Since you only owned the home 11 months, you maximum exclusion is 11/24 x 250,000 = 114,600. As long as your gain is less than $114,600 ($229,000 Married) you will owe no tax. It is not necessary that you buy a new home in order to exclude the gain. You don't even need to report the sale, unless you receive a form 1099-S.
