Arkansas Quarterly Tax FAQ
Arkansas Estimated Quarterly Tax Payments for Self-Employed Workers in 2026
Self-employed workers in Arkansas must pay both federal estimated taxes to the IRS and state estimated taxes to the Arkansas Department of Finance and Administration. Arkansas has a progressive income tax with 3 brackets and rates ranging from 2% to 3.9%. If you expect to owe $1,000 or more in Arkansas state income tax after withholding and credits, you must make quarterly estimated payments using Form AR1000ES.
Arkansas recently reduced its top rate from 4.4% to 3.9% as part of ongoing tax reform. The state uses a unique bracket structure where the top rate of 3.9% is actually lower than the middle bracket rate of 4%.
| Tax Layer | Rate / Range | Filed With | Form |
|---|---|---|---|
| Federal income tax | 10% – 37% | IRS | 1040-ES |
| Self-employment tax | 15.3% | IRS | 1040-ES / SE |
| Arkansas state income tax | 2% to 3.9% | Arkansas Department of Finance and Administration | Form AR1000ES |
How Arkansas Income Tax Affects Your Quarterly Payments
Arkansas taxes personal income — including self-employment income — across 3 progressive brackets. The brackets below apply to single filers for tax year 2026. Married filing jointly thresholds are typically higher.
| Bracket | Taxable Income | Marginal Rate |
|---|---|---|
| 1 | $0 – $5,100 | 2.0% |
| 2 | $5,100 – $10,200 | 4.0% |
| 3 | $10,200+ | 3.9% |
To estimate your Arkansas quarterly payment, calculate your projected state tax liability using the brackets above, then divide by four. Arkansas payments are made to the Arkansas Department of Finance and Administration through their online portal at dfa.arkansas.gov or by mail using Form AR1000ES.
Federal Self-Employment Tax and Quarterly Due Dates
All self-employed workers must pay federal self-employment (SE) tax of 15.3% on 92.35% of net earnings. This consists of 12.4% for Social Security (on earnings up to $184,500 in 2026) and 2.9% for Medicare (no cap). An additional 0.9% Medicare surtax applies to earnings above $200,000 (single filers).
Both Arkansas and federal estimated tax payments follow the same quarterly schedule:
| Quarter | Income Period | Due Date |
|---|---|---|
| Q1 | January 1 – March 31 | April 15, 2026 |
| Q2 | April 1 – May 31 | June 15, 2026 |
| Q3 | June 1 – August 31 | September 15, 2026 |
| Q4 | September 1 – December 31 | January 15, 2027 |
To avoid underpayment penalties, pay at least 100% of your prior-year tax liability (or 110% if your AGI exceeds $150,000) spread across four equal payments, or at least 90% of your current-year tax. You can deduct 50% of your self-employment tax from your adjusted gross income, reducing both your federal and Arkansas taxable income.
