A high-stakes dispute over the city's tax allocation districts could determine whether Atlanta captures billions in future property tax growth for neighborhood revitalization, or whether Atlanta Public Schools and Fulton County keep that revenue instead.

The city is weighing extending its TAD timelines until 2055 to fund Mayor Dickens' $5.5 billion neighborhood reinvestment plan. Two North Fulton legislators, Rep. Chuck Martin (R-Alpharetta) and Rep. Jan Jones (R-Milton), argue that extending TAD timelines effectively creates new TADs and should use a new baseline set at the extension date.

Using the original baselines set between 1992 and 2006 would generate far more tax increment revenue, given how much property values have grown since then across the eight Atlanta TADs covering the BeltLine, Westside, Eastside, and other districts. APS contributes half of the tax increment revenue to each TAD, while Fulton and Atlanta each contribute a quarter.

The question has drawn attention from school board members, county commissioners, and state legislators, with no clear resolution in sight.
