Tennessee ISO AMT in 2024

The 2024 federal AMT exemption, phase-out thresholds, and Tennessee (no state AMT) for ISO exercises.

The 2024 picture for Tennessee residents

Tennessee has no state income tax, so the 2024 tax picture for its residents was entirely federal: ordinary rates up to 37%, capital gains up to 23.8%, and federal Medicare taxes. That was the structural advantage that drove tech-employee relocations into Tennessee throughout the decade.

2024 AMT exemption

The 2024 federal AMT exemption was $85,700 for single filers. The exemption phased out at 25 cents per dollar of AMTI above $609,350, fully eliminating the exemption for higher earners. That is why ISO exercises in Tennessee during 2024 produced AMT bills that surprised people running first-order mental math.

Tennessee layer in 2024

Tennessee did not impose a separate state AMT in 2024, so federal AMT was the only layer. State ordinary tax still applied to any disqualifying disposition income recognized in the same year.
