State Income Tax
Burdens on Low-Income Families in 1997:
Assessing the Burden and Opportunities for Relief
II. State Income Taxes on Poor Families in 1997
The income tax is a major component of state tax systems. Forty-two states levy an income tax, and income tax revenue makes up 32 percent of total state tax revenue nationally. Thus, the design of a state's income tax affects greatly the overall fairness of a state's tax system.
Because the income tax is calculated as a percentage of a taxpayer's income, it is relatively easy both to determine its impact on taxpayers of different income levels and to modify that impact. In general, state income taxes are designed to be at least modestly progressive that is, to take a smaller share of income from lower-income taxpayers than from higher-income taxpayers. This progressivity results from either a rate structure with higher marginal rates as income rises, deductions or credits that reduce tax liability proportionately more for low-income taxpayers, or a combination of these features.
While all state income tax systems are at least somewhat progressive, each system has a different design. One way that income tax systems differ substantially among states is their treatment of families at the lowest end of the economic ladder. This report compares the treatment of poor taxpayers under each state's income tax structure and suggests ways that this treatment could be improved.
The relatively good fiscal condition that many states enjoy this year has resulted in widespread consideration of tax cuts. This is an opportunity for states to make changes in their income tax provisions that will relieve tax burdens on poor families. Unfortunately, most states with below-poverty thresholds have, thus far, failed to take full advantage of this opportunity.
This analysis is particularly important in light of the policy debates that are occurring in many states this year. Policymakers at the state and federal level, both liberal and conservative, have professed their interest in reducing welfare caseloads and helping welfare recipients to make the transition from welfare to work. With the enactment of federal welfare reform, states across the country have moved ahead. In most cases, the policy debate at the state level has focused on changing the provisions of the welfare program itself, while the impact of state tax policy on low-wage working families has been overlooked.
The failure to consider the impact of state tax systems on poor families as a part of the welfare reform debate is a serious omission. Low-income families often face high marginal tax rates; that is, as a family's income rises up to and beyond the poverty level, the combination of higher taxes and the loss of means-tested benefits (such as food stamps) consumes a significant share of these increased earnings.(1) In addition, the expenses of working, such as child care and transportation, often absorb a large proportion of the earnings of low-income workers. Thus, as part of a larger strategy to "make work pay" for low-wage workers, it is particularly important that state income taxes not be imposed on families whose earnings have not yet brought them above the poverty level.
More than a decade ago, the federal government recognized the inconsistency of encouraging poor families to work and then levying taxes that pushed them deeper into poverty. President Ronald Reagan spoke forcefully in the mid-1980's about the foolishness of taxing poor households deeper into poverty. In 1986, as part of an overall tax reform package, the federal government eliminated income tax liability for poor families. Since that time, some states have followed suit, but half still levy taxes on households with earnings below the poverty level.
The impact of state income tax systems on poor families has been increasing in importance in recent years because the number of working poor families has been growing across the United States. The increase in the number of families that have earnings from work but remain poor can be seen by comparing poverty rates in 1996 with those in 1979, two years when the economy was growing and unemployment rates were similar. The poverty rate for families with children in which the head-of-household worked climbed from 7.7 percent in 1979 to 11.0 percent in 1996, an increase of 40 percent.(2) In 1996, roughly 9.5 million poor children two out of every three poor children lived in a family with a working household member.
It is critical that more states address the problem of taxation of poor families, both in the interest of fairness and in order to further the objective of allowing parents who work to support their families adequately. The first step is understanding the extent of the burden families bear and the features of the tax system that affect those burdens.
Income Tax Thresholds
The tax threshold is the entry point into the income tax system. It is the income level at which a family begins to owe state income tax.(3) A state's threshold level is affected by two broad factors.
Income taxes generally are not imposed on total income. States typically allow nearly every taxpayer some subtractions from income, most often through personal and dependent exemptions and/or a standard deduction, before tax liability is calculated. Some states provide this broad tax relief through a tax credit a dollar amount subtracted from the tax bill for each household member or for each dependent. The size of these exemptions, deductions, and credits affects the income level at which families begin to owe tax.
In addition, 23 states target special deductions, exemptions, or tax credits on low-income families.(4) These features affect the tax threshold for low-income families without altering the tax structure for families with higher incomes. (For an explanation of how exemptions, deductions, and credits work, see Chapter IV.)
This report calculates the tax burden on two types of low-income families: a married couple with two children and a single parent with two children. In each case, it is assumed the family has only one wage earner and that the family's income comes entirely from earnings. The tax thresholds are based on each state's personal and dependent exemptions, standard deductions, state earned income tax credits, and other deductions or credits that are available to all low-income taxpayers with children.
The threshold calculations do not incorporate low-income credits that are based in part on factors other than income, such as the dependent care credit, because not all low-income families qualify for these credits and because the value of the credit for the typical family is difficult to identify. For example, a family with pre-school children may have child care expenses that make them eligible for a dependent care credit, while a similar family with older children may not incur such expenses and thus would not be eligible for the credit. In addition, low-income sales tax and property tax credits, which appear on income tax forms in some states, are excluded from the threshold calculations because they are not administered through the income tax in all states and, like a dependent care credit, are based on factors other than income. These credits are administered through the income tax primarily for ease of administration.
Tables 1A and 1B present the 1997 state income tax thresholds for single-parent families of three and two-parent families of four, respectively. The maps on pages 13 and 14 group the states according to their tax thresholds for each type of family in relation to the poverty line. The tables and maps show that:
- In 20 states, the tax threshold for a single parent with two children fell below the poverty line of $12,804 for a family of three. In those states, the average threshold was $4,279 below the poverty line.
- For two-parent families of four, some 21 states had thresholds below the poverty line of $16,405. The average threshold in those states was $6,229 below the poverty line.
- In six states Alabama, Hawaii, Illinois, Kentucky, New Jersey, and Virginia families of three or four with incomes at just half the poverty line had some income tax liability.
- By contrast, the income tax threshold was well above the poverty line in a number of states. For example, nine states did not tax families of four until their incomes were at least $20,000, and the tax threshold for families of three was $18,000 or more in eight states.

There were some common patterns among states that helped determine whether a state had a high threshold or a low threshold. Not surprisingly, the states with the lowest thresholds tended to have very low personal and dependent exemptions and standard deductions. For example, in the eight states with the lowest thresholds, the combined amount of the personal and dependent exemptions and standard deduction for a single-parent family of three averaged only $4,996, or 39 percent of the poverty line, compared with an average of $11,023, or 86 percent of the poverty line, for the other 34 states with an income tax.(5) A similar pattern held for the deductions and exemptions available to a two-parent family of four.
Similarly, most of the states with low income tax thresholds provided little or no targeted income tax relief for low-income residents. Of the eight states with the lowest thresholds for families of three, only Kentucky had an income tax credit for low-income families. New Jersey had a no-tax floor set at $7,500 less than half the poverty level for a family of four. The pattern was similar for states that had the lowest thresholds for families of four.
In contrast, the states with the highest thresholds tended to use tax credits and more generous personal and dependent exemptions and standard deductions to raise the threshold level.(6) The average combined value of the personal and dependent exemptions and standard deduction in the seven states with the highest tax thresholds was higher than the poverty line for both families of four and families of three.(7) In other words, these states generally set basic deductions at a level sufficient to exempt poor families from owing income tax. In addition to these basic deductions, all but one of these states California also offered substantial tax credits or deductions targeted specifically on low-income families that either raised the income tax threshold or lowered taxes for low-income families.
Taxes at the Poverty Line
Levying an income tax on the poor pushes families deeper into poverty, compounding the challenge of making ends meet. The amount of state income tax owed by families with incomes just equal to the poverty line can be quite substantial. In the states with below-poverty tax thresholds, the tax bill for poor families varied greatly in 1997, from as little as a few dollars to more than $500. By contrast, poor families who lived in states with tax thresholds above the poverty line did not owe any income tax, and in a handful of these states, such families actually qualified for a state tax refund.
- Tables 2A and 2B show the state income tax burden on families of three and four with poverty-level income in 1997. The tables show that:
- For families of three living in states with below-poverty tax thresholds, the average income tax liability for a family with income equal to the poverty line was $167. Five states Hawaii, Illinois, Indiana, Alabama, and Kentucky levied a tax of $250 or more on such families.
- The average tax burden for poor two-parent families of four stood at $243 in the states with below-poverty tax thresholds. In six states Arkansas, Alabama, Hawaii, Illinois, Indiana, and Kentucky the income tax bill for such a family exceeded $350. In Kentucky, a family of four with poverty-level income owed $555 in state income taxes in 1997.
- At the other end of the spectrum, families of three with poverty-level incomes qualified for a state tax refund in six states Massachusetts, Minnesota, New Mexico, New York, Vermont, and Wisconsin. Families of four with income equal to the poverty level qualified for refunds in five of these states, all but New Mexico. In the five states other than New Mexico, the refund came as the result of a refundable state earned income tax credit tied to the federal earned income tax credit (EITC), a tax credit for low- and moderate-income workers. The federal EITC is intended to supplement the earnings of working-poor families and complement efforts to help families make the transition from welfare to work. State EITCs build on the strengths of the federal credit by further helping working families escape poverty. State EITCs also serve to offset the sizable burden of state and local sales taxes and property taxes on the poor.
The largest state EITC for families with two children, in Vermont, provided a refund of $868 for a family of three with poverty-level income, and $678 for a poor two-parent family of four.(8) In Wisconsin, the only state in which the EITC was designated to provide a larger benefit to poor families with three or more children than to other poor families, a single-parent family of four with income at the poverty line received a refund of $1,299 as a result of the state EITC. New Mexico's "low income comprehensive tax rebate," which was much smaller than the state EITCs, resulted in a refund of $15 for single-parent families of three but no refund for two-parent families of four at the poverty line.

Taxes at Minimum Wage
A third measure of the burden of state income taxes on poor families is the tax owed by families with minimum wage earnings, an income level that is well below the poverty line. In most states, full-time minimum wage income in 1997 amounted to
$10,157 per year, or 79 percent of poverty for a family of three and just 62 percent of poverty for a family of four.(9) Some eight states that levy income taxes set the minimum wage higher than the federal standard during some or all of 1997. Yet even in these states, minimum wage earnings fell significantly below the poverty line for families of three or four.
A popular stereotype holds that minimum wage workers are mostly teenagers or secondary earners in families that are not poor. Yet the reality is very different from this conception. In 1993, fewer than one in three minimum-wage workers were teenagers, while nearly half were 25 and older. An analysis of the recent increase in the federal minimum wage shows that 40 percent of the additional earnings resulting from the increase will benefit the lowest-income 20 percent of families.(10) Given the reliance of many low-income families on a parent earning the minimum wage, relieving income taxes on families at this income level should be a priority.(11)
Despite the difficulty of supporting a family on minimum wage earnings, a number of states in 1997 levied an income tax on families in which a parent earns at this level. Tables 3A and 3B indicate the income tax liability for single-parent families of three and two-parent families of four with one full-time year-round minimum wage worker. In the eight states with an income tax that also had a minimum wage higher than the federal requirement during some or all of 1997, the tax is calculated for the state-specific minimum wage.
- In 13 states that is, in nearly one-third of states with an income tax single-parent families of three with minimum wage income owed some state income tax. The average income tax on single-parent families of three with minimum wage income in these states was $126. Eight states levied a tax of more than $100, and one state Hawaii imposed a tax of $272 on such a family.
- Two-parent families of four with minimum wage income owed income taxes in ten states. The average tax liability in these ten states was $101.
- By contrast, families with a minimum wage worker qualified for a tax refund in seven states. The five states with refundable state earned income tax credits Minnesota, New York, Vermont, Wisconsin, and Massachusetts provided refunds ranging from $366 to $914 for both families of three and families of four with minimum wage income. In Wisconsin, a family with three children and one minimum wage worker received a refund of $1,540. New Mexico's "low income comprehensive tax rebate" and Georgia's "low-income tax credit" resulted in smaller refunds. The New Mexico credit provided refunds of $40 for a family of four and $30 for a family of three with minimum wage earnings. The Georgia credit provided refunds of $7 for a family of four and $32 for a family of three with minimum wage earnings.

At some income levels, particularly those modestly above the poverty line, workers face marginal tax rates ranging from 67 percent to 79 percent from the combination of federal income and social security taxes, the phaseout of the federal earned income tax credit, and the loss of food stamps.2. Part of this increase reflects growth in the share of working families with children that are headed by a single female parent, since this group is much more likely to be poor than are two-parent families. Nevertheless, the poverty rate among families with a working parent has grown for both single-parent and two-parent families.
3. A state's threshold tax level is not necessarily the same as the income level above which families are required to file an income tax return. For example, many states require families to file a state income tax return if they are also required to file a federal income tax return. (Federal filing requirements in 1997 for most taxpayers under age 65 were gross income of at least $8,550 for a head of household and at least $12,200 for a married couple filing jointly.) Most other states specify a minimum amount of income above which families are required to file that is lower than or equal to the tax threshold level.
4. In one state, Pennsylvania, a low-income "tax forgiveness" credit is the only method used to reduce taxes for low-income residents. The state income tax does not include personal or dependent exemptions, nor a standard deduction.
5. These calculations reflect the combined personal and dependent exemptions and standard deductions at the income tax threshold in each state. They include the relevant amounts allowed on federal income taxes for those states that implicitly incorporate the federal personal and dependent exemptions and standard deduction by using federal taxable income or federal tax liability as the starting points in their state income tax systems. They also include the implicit amounts for Connecticut and Louisiana, states that build some exemptions and standard deductions into their tax tables.
In most states, personal and dependent exemptions were specified amounts that tax filers deduct from their adjusted gross income before computing their tax liability. A small number of states had personal and dependent exemption credits, under which tax filers subtracted a specified amount per exemption or dependent from their calculated tax liability. For states with personal or dependent exemption credits, the credit amount was converted to an equivalent income deduction amount based on the marginal tax rate for a low-income family for purposes of this comparison.
6. The exception was Pennsylvania, which offered neither exemptions nor a standard deduction but still had a relatively high threshold. Pennsylvania relied entirely on a low-income tax credit to avoid levying the income tax on low-income families.
7. The average value of these combined deductions for a family of three equaled 116 percent of the poverty line. The average value of these deductions available to families of four equaled 107 percent of the poverty line.
8.Four other states Iowa, Maryland, Oregon, and Rhode Island also had a state EITC in 1997, but these non-refundable credits could be used only to eliminate taxes on low-income families and not to provide refunds.
9. The federal minimum wage increased from $4.75 an hour to $5.15 an hour on September 1, 1997.

11. It should be noted that states typically do not allow teenagers who can be claimed as a dependent on their parents' income tax return to enjoy the full benefit of personal exemptions, standard deductions, and tax credits on their own income tax returns. Therefore, states can raise income tax thresholds for families with minimum wage income levels without unduly benefitting teenagers in high-income families.
