A dependent is any person whom a taxpayer can claim a dependency exemption for, defined by the Internal Revenue Code as any individual supported by the taxpayer who is related to the taxpayer in specified ways or who makes their principal abode in the taxpayer's household.
In determining taxable income, an individual taxpayer is entitled to a deduction for each allowable personal exemption. This exemption reduces the amount of income subject to tax and can be claimed for the taxpayer, their spouse, and each dependent.
