How do tax credits differ from deductions and how do they affect after-tax income?

• A. Deductions reduce tax owed; credits reduce taxable income.
• B. Deductions reduce taxable income; credits reduce tax owed; credits generally have a larger impact on after-tax income.
• C. Credits increase tax owed.
• D. Deductions and credits have identical effects.

Answer: (B)

The main idea is that deductions and credits affect your finances in different parts of the tax calculation. A deduction lowers the amount of income that gets taxed, so it saves you tax by the amount of the deduction times your marginal tax rate. A tax credit directly reduces the tax you owe, dollar for dollar, and depending on whether it’s refundable or not, it can even lead to a refund beyond any tax owed. Because credits cut the final bill itself, they usually have a larger impact on after-tax income than deductions, especially for people in higher tax brackets. The other possibilities—credits increasing tax owed or deductions and credits having the same effect—don’t fit how these mechanisms work.
