West Virginia ISO AMT in 2025

The 2025 federal AMT exemption, phase-out thresholds, and West Virginia (no state AMT) for ISO exercises.

The 2025 picture for West Virginia residents

In 2025, West Virginia residents paid federal ordinary income tax at brackets topping out at 37%, plus West Virginia state tax up to 4.82%, plus Medicare (1.45% + 0.9% additional above $200k single MAGI), plus a federal supplemental-withholding layer on RSU-style income.

2025 AMT exemption

The 2025 federal AMT exemption was $88,100 for single filers. The exemption phased out at 25 cents per dollar of AMTI above $626,350, fully eliminating the exemption for higher earners. That is why ISO exercises in West Virginia during 2025 produced AMT bills that surprised people running first-order mental math.

West Virginia layer in 2025

West Virginia did not impose a separate state AMT in 2025, so federal AMT was the only layer. State ordinary tax still applied to any disqualifying disposition income recognized in the same year.
