• By Emma Sifre, Marco Guzman
Undocumented immigrants who work and pay taxes but don't have a valid Social Security number for either themselves or their children are excluded from federal EITC and CTC benefits.

Far From Radical: State Corporate Income Taxes Already Often Look Beyond the Water’s Edge
• By Carl Davis, Matthew Gardner
State lawmakers are increasingly interested in reforming their corporate tax bases to start from a comprehensive measure of worldwide profit. This provides a more accurate, and less gameable, starting point for calculating profits subject to state corporate tax. Mandating this kind of filing system, known as worldwide combined reporting (WWCR), would be transformative, as it would all but eliminate state corporate tax avoidance done through the artificial shifting of profits into low-tax countries.
America Used to Have a Wealth Tax: The Forgotten History of the General Property Tax
• By Carl Davis, Eli Byerly-Duke
Over time, broad wealth taxes were whittled away to become the narrower property taxes we have today. These selective wealth taxes apply to the kinds of wealth that make up a large share of middle-class families’ net worth (like homes and cars), but usually exempt most of the net worth of the wealthy (like business equity, bonds, and pooled investment funds).The rationale for this pared-back approach to wealth taxation has grown weaker in recent decades…

Comparing Flat-Rate Income Tax Options for Alaska
• By Carl Davis
Alaska lawmakers are facing an unprecedented fiscal crisis. The state is more dependent than any other on oil tax and royalty revenues but declines in oil prices and production levels have sapped much of the vitality of these revenue sources. One way of diversifying the state’s revenue stream and narrowing the yawning gap between state revenues and expenses would be to reinstitute a statewide personal income tax. Alaska previously levied such a tax until 1980.…

States Should Decouple from Costly Federal Opportunity Zones and Reject Look-Alike Programs
• By ITEP Staff
Post enactment of TCJA, lawmakers in most states needed to decide how to respond to the creation of this new program. Given the shortcomings of the federal Opportunity Zones program and its added potential costs to states, the most prudent course of action is three-pronged: States should move quickly to decouple; states should reject look-alike programs; and lawmakers should make investments directly into economically distressed areas.
