The 2027 picture for Arkansas residents
In 2027, Arkansas residents paid federal ordinary income tax at brackets topping out at 37%, plus Arkansas state tax up to 3.9%, plus Medicare (1.45% + 0.9% additional above $200k single MAGI), plus a federal supplemental-withholding layer on RSU-style income.
2027 AMT exemption
The 2027 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 Arkansas during 2027 produced AMT bills that surprised people running first-order mental math.
Arkansas layer in 2027
Arkansas did not impose a separate state AMT in 2027, so federal AMT was the only layer. State ordinary tax still applied to any disqualifying disposition income recognized in the same year.
