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.

Federal decisions are italicized.

  5. 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).
