The Combined Rate accounts for Federal, State, and Local tax rate on capital gains income, the 3.8 percent Surtax on capital gains and the marginal effect of Pease Limitations (which results in a tax rate increase of 1.18 percent).
Delaware allows some or all of federal income tax paid to be deducted from state taxable income. Delaware allows for a Tax Credit instead of a deduction for taxes paid in other states. In addition to the personal income tax rates, Delaware imposes a tax on lump-sum distributions.
