How Much Is a Dependent Really Worth on Your Taxes?
Claiming a dependent no longer shrinks your taxable income the way it used to — the personal exemption disappeared back in 2018. Instead, dependents unlock tax credits, which are more valuable because they cut your tax bill dollar-for-dollar instead of just lowering the income you're taxed on. A qualifying child under 17 is worth up to $2,000 through the Child Tax Credit, with up to $1,700 of that potentially refundable even if you owe no tax at all. A dependent who doesn't meet the child criteria — an adult child, an elderly parent, or another qualifying relative — still earns you $500 through the Credit for Other Dependents.
Both credits shrink once your income climbs high enough. The phase-out starts at $200,000 of AGI for single and head-of-household filers, or $400,000 for married couples filing jointly, and reduces your combined credit by $50 for every $1,000 you're over that line. Enter your number of qualifying children, other dependents, filing status, and AGI, and this tool works out your credit before and after the phase-out so you know exactly what to expect on your return.
