Many states' transportation budgets are in disarray, in part because they are trying to cover the rising cost of asphalt, machinery, and other construction materials with a gasoline tax rate that is rarely increased. A growing number of states have recognized the problem with this approach and have switched to a "variable-rate" gas tax under which the tax rate tends to rise over time alongside either inflation or gas prices. A majority of Americans live in a state where the gas tax is automatically adjusted in this way.

When thinking of tax havens, one generally pictures notorious zero-tax Caribbean islands like the Cayman Islands and Bermuda. However, we can also find a tax haven a lot closer to home in the state of Delaware - a choice location for U.S. business formation. A loophole in Delaware's tax code is responsible for the loss of billions of dollars in revenue in other U.S. states, and its lack of incorporation transparency makes it a magnet for people looking to create anonymous shell companies, which individuals and corporations can use to evade an inestimable amount in federal and foreign taxes.

Sluggish gas tax revenue growth has put strain on transportation budgets at the federal and state levels, and has led to countless debates around the country about how best to pay for America's infrastructure.

In most states, the gasoline tax is set at a fixed number of cents per gallon of gas. South Carolina drivers, for example, have been paying 16 cents per gallon in state tax for more than a quarter century.1 But while this type of fixed-rate gas tax may appear to be flat over time, its lack of change in the face of inflation means that its "real" value, or purchasing power, is steadily declining. In ten states, this decline has brought the state's inflation-adjusted gas tax rate to its lowest level in the state's history.
