Alaska | #4 Overall
Alaska, which forgoes an individual income tax and a state-level sales tax, ranks well on the Index due to the absence of major taxes, but has room to reform the taxes it does impose. Cities and boroughs can impose their own sales taxes, resulting in a lack of base uniformity, though local governments have agreed to adopt a uniform code with central administration for remote sellers, lessening compliance burdens.
The state’s corporate income tax has a 20 percent net CFC-tested income (NCTI) inclusion, making it a national outlier. Alaska also imposes a throwback rule, exposing some out-of-state activity of Alaska-based corporations to the state’s corporate taxes, and it only partially conforms to federal depletion allowances. Property taxes are somewhat high, and the state taxes some inventory, but with no individual income tax, state sales tax, capital stock tax, or inheritance or estate tax, Alaska keeps taxes low for most residents and for some businesses, particularly those not subject to production taxes (e.g., oil and natural gas).

Electric Vehicle Tax Treatment by State, 2026
As the market share of electric vehicles (EVs) on the road grows, the gas tax’s ability to fund road projects and decrease traffic congestion erodes. Both federal and state real tax revenue per vehicle mile traveled has been on a steady decline for decades, creating a fiscal gap for road expenditures even as the demand for road infrastructure improvements has grown.
