State Income Taxes and Credits


Most states levy state income taxes, but the tax burden on low-income families varies significantly depending on where they live. A growing number of states offset this burden with state earned income tax credits and/or state child and dependent care tax credits. These credits are typically based on provisions in the federal income tax code, but states make all decisions regarding eligibility and benefit levels. [More detail...]

Data Notes and Sources

Data on State Income Taxes and Credits were compiled by NCCP in June 2009. Some state policy decisions may have changed since these data were collected.

  2. State EITC Online Resource Center, http://www.stateeitc.com (accessed June 3, 2009); with additional information from NCCP.
  3. The limit for a two-parent family with one qualifying child is $40,463 per year ($45,295 per year for two qualifying children and $48,279 with three or more qualifying children).
  4. Value reflects state's refundable credit; filers may claim either the refundable credit or a nonrefundable credit of 50 percent of the federal EITC.

Washington, DC: National Women's Law Center.
  6. Maryland offers a child care deduction and a child care credit (some filers may claim both). The deduction has no income eligibility limit, but the credit is limited to filers with income of $50,000 per year or less.
  7. These include care expenses for children under 13 years that allowed the claimant to work or look for work, up to a maximum of $3,000 per year for one child and $6,000 per year for two or more children. Claimed expenses may not exceed claimant's earnings, or, in two-parent families, the earnings of the lesser-earning parent; full-time students are treated as having $250 per month in earned income (or $500 per month in families with two or more children).

  8. Maryland offers a child care deduction and a child care credit (some tax filers may claim both). Both follow federal rules regarding eligible child care expenses and are nonrefundable.
  9. Tax deductions are subtracted from a claimant's income before calculating taxes, while credits are subtracted from the claimant's tax liability after taxes are calculated. Maryland's top tax rate is 4.75 percent.
  10. Figure reflects the maximum benefit for tax filers claiming both the maximum deduction ($143 per year for one child, $285 per year for two or more) and the max credit ($341 per year for one child, $683 per year for two or more); the benefit cannot exceed the claimant's tax liability.
