The Arkansas 529 Plan Tax Benefit Calculator estimates the state income tax you save by contributing to an Arkansas-sponsored 529 college savings plan. Arkansas offers a state income tax deduction — not a credit — of up to $5,000 per taxpayer ($10,000 for a married couple filing jointly). Because it is a deduction, your actual savings depend on your marginal Arkansas tax rate, and any contribution above the cap can be carried forward for up to four more years.
How it works
A deduction reduces your taxable income, so the cash value of the deduction is the deductible amount multiplied by the rate at which that income would otherwise be taxed. The tool first caps your contribution at the annual limit for your filing status, then applies your marginal rate:
deductible = min(contribution, cap) // cap = 5000 single, 10000 joint
tax_savings = deductible x marginal_rate
carryforward = max(contribution - cap, 0) // usable over the next 4 years
Arkansas’s top marginal income tax rate has been reduced in recent years to about 3.9%, so the maximum first-year benefit of a fully-funded deduction is modest in dollar terms but compounds with the plan’s tax-free growth.
Example and notes
A married couple contributing $12,000 jointly can deduct the full $10,000 cap this year, saving about $390 at a 3.9% rate, and carry forward the remaining $2,000 to deduct next year. A single filer contributing $5,000 deducts the whole amount and saves about $195.
Remember the headline value of a 529 is tax-free growth and withdrawals for qualified education expenses — the state deduction is a bonus on top. To qualify for the Arkansas deduction you must use the in-state Arkansas plan. Confirm the current caps and rate with the Arkansas DFA before filing.
