## What this estimate simplifies

-   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.
-   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 2 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 4.5 percent instead of 2 percent. Each single taxpayer whose Connecticut AGI exceeds $105,000 shall pay an amount equal to $25 for each $5,000, or fraction thereof, by which the taxpayer's Connecticut AGI exceeds $105,000, up to a maximum payment of $250. 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 2 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 2 percent tax rate does not apply shall be an amount to which the 4.5 percent tax rate shall apply. Each MFJ filer whose Connecticut AGI exceeds $210,000 shall pay an amount equal to $50 for each $10,000, or fraction thereof, by which the taxpayer's Connecticut AGI exceeds $210,000, up to a maximum payment of $500. Additionally, 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.
-   Connecticut taxpayers are also given personal tax credits (1-75%) based upon adjusted gross income.
-   Connecticut's personal exemption phases out by $1,000 for each $1,000, or fraction thereof, by which a single filer's Connecticut AGI exceeds $30,000 and a MFJ filer's Connecticut AGI exceeds $48,000.
