If you are a resident of Mexico or Canada or a national of the United States, you can also claim a personal exemption for your spouse if your spouse had no gross income for U.S. tax purposes and was not the dependent of another taxpayer. In addition, you can claim exemptions for your dependents who meet certain tests.
But the extra expense of additional family members can put a financial strain on you. The rising costs of food, electricity, gas and water can all add up quickly. To help you get back on track, you might be able to claim these housemates on your taxes, just like your children, if they meet certain criteria. There are a few simple rules to help you decide who you should and shouldnât claim as a dependent: DO claim all children that were born within the tax year. Even if your child was born on December 31, they may be able to be claimed as a dependent on your taxes. DONâT claim a child that has lived with you for less than six months of the year.
