Quarterly Estimated Tax Calculator — Arkansas (2026)
If you earn income in Arkansas without withholding — freelancing, contracting, rentals, dividends — the IRS expects payment four times a year, not once. This calculator turns your expected 2026 net profit into a per-quarter number covering self-employment tax, federal income tax and Arkansas state tax. Arkansas uses a progressive income tax with 4 brackets running from 0.00% up to 3.90%, applied after a state standard deduction of $2,340.

2026 due dates and safe harbor
Federal estimated payments are due April 15, June 15, September 15 of 2026 and January 15 of 2027. You avoid penalties by paying either 90% of the current year's liability or 100% of last year's (110% if prior-year AGI exceeded $150,000) — the safe-harbor rule.
Arkansas runs its own estimated-payment schedule that usually mirrors the federal dates. On $90,000 of net profit the Arkansas portion alone is about $706 per quarter.
Underpayment penalties
The IRS charges interest-style penalties per quarter you fall short, currently around 7–8% annualized. Paying late in the year does not fix an early-quarter shortfall unless you use the annualized income method on Form 2210.
Irregular income is common in retail (Walmart HQ) work around Little Rock: if Q1 is slow and Q4 is huge, the annualized method usually beats four equal payments.
Paying as a Arkansas taxpayer
Pay federally through IRS Direct Pay or EFTPS, and Arkansas through the state revenue department's online portal — keep confirmation numbers for both.
Arkansas has no separate city or county income tax, so the state figure above is the full sub-federal income tax you pay.
Local and payroll taxes Arkansas adds on top
Arkansas adds no state-mandated employee payroll deduction beyond FICA, so nothing extra is taken from your gross pay at the state level.
Arkansas has no separate city or county income tax, so the state figure above is the full sub-federal income tax you pay.
Nobody withholds these for you when you are self-employed in Arkansas. Local wage taxes, city business licences and gross-receipts style levies are yours to register for and remit alongside your quarterly federal and state estimates.
Working across a state line from Arkansas
Arkansas has no income-tax reciprocity agreements, so if you live here and work across a state line you generally file a nonresident return in the work state and claim a credit at home to avoid double taxation.
Remote and hybrid work complicates this further: most states tax income where the work is physically performed, so a Little Rock resident spending part of the year at a client site in Texas may owe a nonresident return there. Keep a day-count log if you split time between states.
The rest of your Arkansas tax bill
Arkansas charges a 6.5% state sales tax, homeowners pay an average effective property tax of 0.62% of market value, and the minimum wage in force during 2026 is $11.00 an hour.
Local add-ons bring the average combined rate near 9.4%.
Income tax is only one part of a state's take. Arkansas recovers revenue through sales and property tax as well, which is why headline income tax rates alone are a poor guide to how far a salary really goes. Arkansas exempts Social Security and the first $6,000 of pension or IRA distributions.
Arkansas vs Texas on the same salary
On a $90,000 salary, a single filer keeps about $69,074 a year in Arkansas against roughly $72,145 in Texas — a difference of $3,071, or $256 a month.
Effective combined rates are 23.3% in Arkansas and 19.8% in Texas. Set that gap against living costs: index 89 here versus 92 there, with property tax at 0.62% and 1.68% respectively.
