Tax Credits and Reading Form 1040

Tax deductions reduce your taxable income — their value depends on your marginal tax rate. A $1,000 deduction for someone in the 22% bracket saves $220 in tax. For someone in the 12% bracket, the same deduction saves only $120. Tax credits, by contrast, reduce your tax liability dollar-for-dollar — a $1,000 credit saves exactly $1,000 regardless of your bracket. This makes credits significantly more valuable than deductions of the same dollar amount. There are two types of credits: non-refundable credits can reduce your tax liability to zero but not below (you don't get the excess as a refund). Refundable credits can reduce your tax liability below zero — the government pays you the excess as a refund even if you owe no tax. Partially refundable credits allow a portion of the excess to be refunded. Examples: the Child Tax Credit is partially refundable (the Additional Child Tax Credit portion is refundable). The Earned Income Credit is fully refundable. The American Opportunity Credit is partially refundable (40% refundable). Understanding refundability is essential — fully refundable credits are the most valuable for lower-income taxpayers who owe little or no tax.
