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.
You can claim a person as your dependent if all 3 of these statements are true: They are a U.S. citizen, U.S. national, resident alien, or resident of Canada or Mexico. There is an exception for legally adopted children.ou can claim one exemption for each dependent. A dependent exemption is technically different from a tax deduction for dependents, because an exemption is subtracted from your adjusted gross income before your taxable income is calculated (after that, tax deductions are subtracted from your taxable income).
