How it works

A marriage penalty occurs when combined tax as MFJ exceeds the sum of two single returns—common when both spouses earn similar incomes. A bonus occurs when one spouse earns much more—the lower earner's income is effectively taxed at a lower rate. The 2017 TCJA reduced penalties for most couples but they persist at higher income levels. AMT, EITC, and ACA subsidies also create marriage effects.
