(a) Local income taxes are excluded. Eleven states have county- or city-level income taxes; the average rates expressed as a percentage of AGI within each jurisdiction are: AL–0.10%; DE–0.16%; IN–0.61%; IA–0.11%; KY–1.31%; MD–2.38%; MI–0.17%; MO–0.21%; NY–1.59%; OH–1.56%; PA–1.22%. In CA, CO, KS, NJ, OR, and WV some jurisdictions have payroll taxes, flat-rate wage taxes, or interest and dividend income taxes. See Jared Walczak, “Local Income Taxes in 2019,” Tax Foundation, July 30, 2019, https://taxfoundation.org/local-income-taxes-2019/. +256:293+256:289
(b) These states allow some or all of federal income tax paid to be deducted from state taxable income.
(c) For single taxpayers with AGI below $25,500, the standard deduction is $3,000. This standard deduction amount is reduced by $25 for every additional $500 of AGI, not to fall below $2,500. For Married Filing Joint (MFJ) taxpayers with AGI below $25,500, the standard deduction is $8,500. This standard deduction amount is reduced by $175 for every additional $500 of AGI, not to fall below $5,000. For all taxpayers with AGI of $20,000 or less and claiming a dependent, the dependent exemption is $1,000. This amount is reduced to $500 per dependent for taxpayers with AGI above $20,000 and equal to or less than $100,000. For taxpayers with more than $100,000 in AGI, the dependent exemption is $300 per dependent.
(d) Statutory rates and brackets for 2023 are shown. Brackets are adjusted annually for inflation, but 2023 inflation adjustments were not available as of publication.

(h) Rates apply to individuals earning more than $84,500. A separate tax tables exist for individuals earning $84,500 or less, with rates of 2 percent on income greater than or equal to $5,000; 3 percent on income greater than or equal to $10,000; 3.4 percent on income greater than or equal to $14,300; and 4.9 percent on income greater than $23,600 but less than or equal to $84,500.
(i) Standard deduction or personal exemption is structured as a tax credit.
(j) Connecticut and New York have “tax benefit recapture,” by which many high-income taxpayers pay their top tax rate on all income, not just on amounts above the benefit threshold.
(k) Bracket levels adjusted for inflation each year. Inflation-adjusted bracket widths for 2023 were not available as of publication, so table reflects 2022 inflation-adjusted bracket widths.
(l) Exemption credits phase out for single taxpayers by $6 for each $2,500 of federal AGI above $229,908 and for MFJ filers by $12 for each $2,500 of federal AGI above $459,821. The credit cannot be reduced to below zero.
(m) Rates include the additional mental health services tax at the rate of 1 percent on taxable income in excess of $1 million.
(n) State provides a state-defined personal exemption amount for each exemption available and/or deductible under the Internal Revenue Code.

Because it is still available, these state-defined personal exemptions remain available in some states but are set to $0 in other states.
(o) Standard deduction and/or personal exemption adjusted annually for inflation, but the 2023 inflation adjustment was not available at time of publication, so table reflects actual 2022 amount(s).

(q) Connecticut has a complex set of phaseout provisions. For each single taxpayer whose Connecticut AGI exceeds $56,500, the amount of the taxpayer’s Connecticut taxable income to which the 3 percent tax rate applies shall be reduced by $1,000 for each $5,000, or fraction thereof, by which the taxpayer’s Connecticut AGI exceeds said amount. Any such amount will have a tax rate of 5 percent instead of 3 percent. Additionally, each single taxpayer whose Connecticut AGI exceeds $200,000 shall pay an amount equal to $90 for each $5,000, or fraction thereof, by which the taxpayer’s Connecticut AGI exceeds $200,000 but is less than $500,000, and by an additional $50 for each $5,000, or fraction thereof, by which the taxpayer’s AGI exceeds $500,000, up to a maximum payment of $3,150. For each MFJ taxpayer whose Connecticut AGI exceeds $100,500, the amount of the taxpayer’s Connecticut taxable income to which the 3 percent tax rate applies shall be reduced by $2,000 for each $5,000, or fraction thereof, by which the taxpayer’s Connecticut AGI exceeds said amount. Any such amount of Connecticut taxable income to which, as provided in the preceding sentence, the 3 percent tax rate does not apply shall be an amount to which the 5 percent tax rate shall apply. Each MFJ taxpayer whose Connecticut AGI exceeds $400,000 shall pay, in addition to the amount above, an amount equal to $180 for each $10,000, or fraction thereof, by which the taxpayer’s Connecticut AGI exceeds $400,000, up to a maximum of $5,400, and a further $100 for each $10,000, or fraction thereof, by which Connecticut AGI exceeds $1 million, up to a combined maximum payment of $6,300.

Haw. Rev. Stat. § 235-51 (2015).
