Overview: The Head of Household Tax Break Was Built for Single Mothers. It Rewards the Wrong Ones.
In a piece reprinted from the Washington Informer, Beverly Moran and LaToya B. Parker examine the head of household tax filing status, created in 1951 to ease the burden on single parents. Drawing on IRS microdata, they show the benefit scales with income rather than need, saving a taxpayer at the 25th income percentile about $23 a year compared to $1,573 for one at the 75th percentile. Black women make up 21.6% of all head of household filers, and the piece warns that current proposals, including Project 2025, could eliminate or restructure the status in ways that raise taxes on single-parent households.
The head of household filing status is popularly understood as a tax break for single mothers, a modest acknowledgment that raising children alone costs more than doing it with a partner. That image is not wrong exactly.
Roughly 79% of head of household filers are women, and the status was created in 1951 specifically to ease the tax burden on unmarried taxpayers supporting dependents.
Roughly 21 million tax returns claim the status, about 1 in every 7 filed. But the way head of household is designed contradicts the way it is perceived.
Rather than targeting need, it distributes its largest benefits to the filers who need it least, and the mismatch is no longer academic, because the status itself is now a target.
A Structural Design That Favors High Earners
Consider income. Drawing on IRS Statistics of Income microdata, researchers found that in 2011 a taxpayer at the 25th percentile of the income distribution filing as head of household saved about $23 a year, while a taxpayer at the 75th percentile saved $1,573, a 68-fold gap.
The mechanism is structural: head of household status works by raising the income thresholds at which higher tax brackets apply, so the benefit accrues only after a filer’s income has climbed above them. Low earners have crossed few or none.
The Tax Policy Center estimates that only about 8% of the lowest-income families with children benefit from the status at all, since many owe no federal income tax to offset in the first place.
The Disproportionate Impact on Black Women
Race and gender compound this mismatch. The IRS collects no information on filers’ race or sex, so this dimension is inferred from census data rather than measured directly.
Black people constitute 25.5% of all head of household filers, roughly 1.8 times their 14% share of the general population.
Black filers claiming the status are 84.5% female, meaning Black women alone make up 21.6% of every head of household filer in the country. The group most associated with the policy’s image is overrepresented among its filers, while the design ensures the smallest benefits flow to those with the least income.
Double Jeopardy in the U.S. Tax Code
This pattern is not new to tax scholarship. As of 2024, 48% of Black adults had never married, compared with 29% of non-Black adults, so a tax code in which marriage frequently delivers a bonus averaging more than $3,000, while the unmarried head of household receives $23 at the bottom of the income scale, is not neutral in effect.
For Black women raising families on a single income, it is double jeopardy: penalized once by a benefit structure that pays the most to the highest earners, and again by a code built around a household form they are statistically least likely to occupy.
The benefit also does not scale with the number of dependents a filer supports; a parent raising one child receives the same benefit as a parent raising four, unlike the Child Tax Credit or the Earned Income Tax Credit.
Political Threats and Proposed Reform
The political stakes are current rather than historical. Project 2025 called for eliminating the status outright, and a Senate bill drafted by the Niskanen Center would raise taxes on roughly two-thirds of single-parent households to help fund an expanded Child Tax Credit, a trade that deserves scrutiny given how many low-income children the credit already leaves out.
None of this argues for preserving head of household as it stands. Scholars have proposed replacing it with a flat per-child credit that would produce net gains for roughly the bottom four income deciles, one that grows with the number of children a parent raises and reaches families whose earnings are too low to owe much income tax.
The real choice is between redesigning this benefit so it reaches the single mothers it was named for, and quietly raising taxes on those same women while pointing to a tax break most of them barely receive.
