What Arkansas residents actually pay
Arkansas taxes ordinary income at a top marginal rate of 3.9%. RSU settlement value, NSO exercise spread, and ESPP discount income all count as ordinary wages for this purpose and flow through the state's normal brackets.

Traditional 401(k) in Arkansas
A pre-tax 401(k) contribution reduces both federal and Arkansas taxable income today. At the top bracket, every $1,000 contributed saves 38.9 cents on the dollar (federal 35% + state 3.9%). At retirement, withdrawals are taxed at your then-current bracket.
Roth 401(k) breakeven
Roth 401(k) contributions are taxed at today's rates; withdrawals are tax-free. The Roth choice beats traditional when your retirement bracket is higher than your contribution bracket. For equity earners in high-income years, traditional is usually right during big RSU years and Roth is right during low-income transition years.
Mega-backdoor Roth
After-tax 401(k) contributions above the standard $23,500 limit can be converted to Roth in plans that allow it. For high earners in Arkansas, this is the largest tax-advantaged bucket available after the primary 401(k) and IRA caps. Check whether your plan allows after-tax contributions and in-plan Roth conversions.
Frequently asked
- Does Arkansas tax RSU income the same as wages?
- Yes. Arkansas treats RSU ordinary income as wages, taxable at the state's top marginal rate of 3.9%. Supplemental-wage federal withholding (22%, or 37% above $1M YTD) does not adjust for state withholding, so you often owe extra at filing.
- What happens if I exercise ISOs while living in Arkansas?
- Arkansas does not run a separate state AMT, so only federal AMT applies. You still need to model the bargain element carefully if you plan a cashless exercise-and-sell.
- I moved to Arkansas from another state. Who taxes my vesting RSUs?
- Most high-tax states (CA, NY, MA) source RSU ordinary income to workdays between grant and vest. If your grant pre-dates your Arkansas move, expect the old state to tax the portion of each tranche attributable to workdays earned there. Arkansas taxes the remainder.
- Can I reduce Arkansas taxes by timing my RSU sales?
- Arkansas gives preferential treatment to long-term capital gains. Holding RSU shares 12+ months past vest can produce both federal and state savings. Weigh concentration risk before using this as a reason to hold.
