DC’s tax system is markedly regressive. This is driven largely by the regressive impact of the city’s sales, excise, and property taxes. The personal income tax is the only effective tool that DC has available for offsetting this regressivity. In the comments below I discuss four options for fine-tuning DC’s income tax to lessen its impact on moderate- and middle-income taxpayers. I also describe four options for funding those tax cuts with policies that would increase upper-income taxpayers’ effective tax rates to be more in line with those paid by their less affluent neighbors.
