Does tax increment financing actually create new growth, or just shift it around?

In short: Tax increment financing promises to revitalize blighted areas by borrowing against future property tax gains. While popular across the United States, critics argue it often subsidizes development that would have happened anyway, potentially starving schools and public services of essential funding while favoring politically connected developers over the public good.

Tax increment financing, or TIF, functions by designating a specific district for redevelopment. Municipalities then freeze the property tax revenue at current levels for that area, diverting all future tax increases—the 'increment'—to pay off bonds issued for infrastructure or project costs. The logic is that public investment will trigger private growth, creating a self-funding cycle of revitalization. By 2004, every U.S. state except Arizona had authorized this mechanism, with thousands of districts currently operating.

However, the effectiveness of TIF is heavily contested. Research suggests that cities using TIF may grow more slowly than those that do not. Economists like David Merriman have noted that TIF often merely shifts development from one location to another or changes its timing rather than generating net new economic activity. Furthermore, because TIF districts capture future tax revenue, they can create a shortfall for other entities like school districts and county governments, which must then raise levies elsewhere to compensate. In some cases, this leads to 'over-TIFing,' where governments take on risky projects that compromise public services.

The definition of 'blighted' has also expanded to include nearly any land, including farmland, leading to accusations of abuse. Critics point to instances where districts are drawn around areas that would have developed regardless, or where TIF facilitates eminent domain for private gain, as seen in the Kelo v. City of New London case. While some cities have implemented transparency measures, such as Chicago's 2009 TIF Sunshine Ordinance, the fundamental tension remains: TIF is a powerful tool for urban renewal that frequently risks subsidizing private interests at the expense of the broader public tax base.
