Governors and legislators in 18 states will be able to claim credit for cutting billions of dollars in taxes heading into an election year, according to a new report.

The report, from the conservative American Legislative Exchange Council, catalogues the tax-cutting states, which stretch from Alaska to Florida. The bulk of those states — 13 of the 18 — have both Republican governors and Republican legislatures. A 14th, Nebraska, technically has a non-partisan unicameral legislature, though conservatives dominate the chamber.

Democratic governors of Montana and Arkansas signed tax-cut packages, while Democratic legislative chambers in Iowa and New Mexico passed their own tax cuts.

Here’s where states cut taxes in 2013:

* Note: States estimate the impact of tax cuts over different budget cycles, some in one-year segments, others over two-, three- or five-year periods.

** Nebraska’s Department of Revenue estimated the AMT cut will have a $7.8 million fiscal impact in FY 2014-2015.

Several other states are expected to revisit their tax codes when legislative sessions kick off next year. In Nebraska, Gov. Dave Heineman (R) pursued a more aggressive tax-cutting agenda, but legislators couldn’t come to an agreement this year.
