Many people confuse them. They apply the 15.3% federal rate to everything, or assume Arkansas has its own self-employment tax. Others miss quarterly payments and learn about penalties in April.
This guide covers who owes what, how net profit drives the math, which forms to file, and when payments are due. Rates and deadlines change each year, so confirm current figures with the IRS and the Arkansas Department of Finance and Administration (DFA) before you file.
Key Takeaways
- Federal self-employment tax and Arkansas income tax are separate taxes.
- Tax starts with net profit after expenses, not gross receipts.
- You may owe federal and Arkansas estimated payments during the year.
- Keep clean records, and verify every current-year rate, form and deadline.
Arkansas Self-Employment Tax Basics
Who counts as self-employed
The IRS treats sole proprietors, independent contractors, partners and anyone in business for themselves as self-employed, including part-time work. Common examples:
- Freelancers and contractors receiving Form 1099-NEC
- Gig and platform workers
- Single-member LLC owners (generally disregarded for federal income tax)
- Partners, who receive a Schedule K-1 showing their share of income, deductions and credits
Schedule SE generally applies once net earnings reach $400. Income without a 1099 is still taxable. For 2026, the general 1099-NEC reporting threshold is $2,000, and the 1099-K threshold for payment networks is more than $20,000 and more than 200 transactions. Those thresholds decide who sends a form, not what you owe.
Three taxes, three purposes
Federal self-employment tax funds Social Security and Medicare. Federal income tax and Arkansas income tax fund general government. According to IRS self-employment tax guidance, the rate is 15.3%: 12.4% Social Security and 2.9% Medicare.
Arkansas taxes your Schedule C net profit through its individual income tax return. Arkansas does not impose a separate self-employment tax or state SE schedule. Confirm this with DFA for your business structure.
From gross receipts to net profit
Net profit is receipts minus ordinary and necessary expenses. Typical ones include supplies, advertising, professional fees, business insurance, software, phone costs, and eligible vehicle or home-office costs. Personal portions don't count.
A freelancer billing $100,000 who spends $18,000 on legitimate costs has $82,000 of net profit. That figure drives the tax.
Special situations
- W-2 plus self-employment income: Wages count toward the Social Security ceiling, which can reduce the SE tax on your side income.
- S corporation owners: You must pay yourself reasonable compensation before taking distributions. The IRS can reclassify distributions as wages.
- Limited partners: Distributive shares generally escape SE tax, but guaranteed payments for services don't.
- Multiple businesses or a spouse's income: Each person's net earnings are generally figured separately.
Residency and income source
Arkansas residency determines your return:
- Full-year residents file AR1000F.
- Part-year residents and nonresidents file AR1000NR.
- Work physically performed in Arkansas is Arkansas-source income. If you work both inside and outside the state, you must allocate.
Domicile means your intended permanent home. Don't assume your status without reviewing your facts against DFA's instructions.
How to Calculate Arkansas Self-Employment Tax
The federal self-employment tax sequence
- Total business income
- Subtract allowable deductions to reach net profit
- Multiply net profit by 92.35% to get net earnings subject to SE tax
- Apply 12.4% up to the Social Security ceiling ($184,500 for 2026, shared with any W-2 wages) and 2.9% Medicare on everything
- Add the 0.9% Additional Medicare Tax if combined wages and SE income exceed $200,000 (single), $250,000 (married filing jointly) or $125,000 (married filing separately)
Schedule SE does the work, and Schedule 1 carries the result to your Form 1040.
What reduces income tax but not SE tax
Half of your SE tax is deductible on Schedule 1 (line 15). That lowers income tax only. The same goes for:
- Self-employed health insurance (Form 7206)
- SEP, SIMPLE and solo 401(k) contributions
- The qualified business income (QBI) deduction, generally up to 20% of qualifying income (Forms 8995 or 8995-A)
None of these shrink the Schedule C profit used for SE tax. Business expenses do.
Estimating Arkansas income tax
Arkansas has its own brackets, deductions and credits. Don't multiply profit by 15.3% and call it a state liability.
Act 2, approved May 6, 2026, sets a 3.7% top rate beginning with tax year 2026. DFA's published 2026 formula uses a $2,470 standard deduction and graduated rates from 0% up to the top rate.
The 2026 estimated-tax worksheet still prints a 3.9% rate that conflicts with Act 2, so check current DFA guidance.
Arkansas lets you deduct self-employed health insurance and Keogh/SEP/SIMPLE contributions. DFA's 2025 adjustment list doesn't mention the federal half-SE-tax or QBI deductions, so don't carry those over without confirming.
Hypothetical example: $100,000 net profit
Assumptions: 2026, single filer, Arkansas full-year resident, sole proprietor, no W-2 income, no other deductions, standard deduction, QBI-eligible, no Arkansas credits beyond the personal credit.
| Item | Estimate |
|---|---|
| Net earnings ($100,000 x 92.35%) | $92,350 |
| Federal SE tax (15.3%) | about $14,130 |
| Half-SE deduction | about $7,065 |
| Federal taxable income (after $16,100 standard deduction and QBI) | about $61,470 |
| Federal income tax (2026 brackets) | about $8,235 |
| Arkansas income tax | roughly $3,200 to $3,600 |
The Arkansas range reflects uncertainty about which federal deductions the state allows and the exact final formula. Treat every figure as an illustration, not advice. Use the current IRS tables and DFA's annual instructions, or a professional, for your real numbers.
Filing and Paying Arkansas Self-Employment Taxes
What you file
- Sole proprietors and single-member LLCs: Form 1040 with Schedule C, Schedule SE and Schedule 1. Attach Schedule C to your Arkansas return, as DFA directs.
- Partnerships: Form 1065 and K-1s. Partners report their shares personally.
- S corporations: Form 1120-S.
- Arkansas: AR1000F for residents, AR1000NR for part-year residents and nonresidents, with schedules such as AR1000ADJ and AR1000TC as needed.
Quarterly estimated payments
Federal: You generally need estimates if you expect to owe at least $1,000 after withholding and credits. You avoid penalties by paying the smaller of 90% of this year's tax or 100% of last year's (110% if prior-year AGI exceeded $150,000). Uneven income can use Form 2210, Schedule AI.
Arkansas: The AR1000ES applies when expected tax exceeds $1,000. Its underpayment rules differ from the federal ones, so don't assume the federal 100%/110% safe harbors carry over. Uneven income can use AR2210A.
Payment workflow
- Estimate your annual net profit and the resulting federal and Arkansas taxes.
- Divide the amounts by installment, or use the annualized method for lumpy income.
- Pay federal estimates through IRS Direct Pay, your IRS Online Account or EFTPS.
- Pay Arkansas through DFA's ATAP portal, by mailed check with a voucher, or by card (a fee applies). The 2026 estimate voucher identifies the tax year.
- Select the correct tax type and period, and save every confirmation.
Deadlines
| 2026 installment | Federal and Arkansas due date |
|---|---|
| First | April 15, 2026 |
| Second | June 15, 2026 |
| Third | September 15, 2026 |
| Fourth | January 15, 2027 |
For 2025 returns, the original deadline was April 15, 2026. Federal Form 4868 extends filing to October 15, 2026, but not payment.
Arkansas accepts the federal extension and generally adds a month, with November 15 stated in its instructions. Without a federal extension, request AR1055-IT by the original deadline.
Weekends, holidays and disaster relief can shift dates. Check the IRS disaster calendar and DFA's deadline notices. The federal failure-to-pay penalty is generally 0.5% per month, up to 25%.
When professional help makes sense
Consider an accountant if you have:
- Income that swings widely between quarters
- Work in multiple states
- An LLC, or an S corporation election in mind
- Employees or contractors to pay
- A foreign owner or foreign income
- An IRS or DFA notice
- Incomplete books
VJM Global, a firm of Chartered Accountants, provides outsourced bookkeeping, accounting, tax compliance and financial reporting support for U.S.-based businesses, including individual Form 1040 preparation. It doesn't operate an Arkansas office.
Deductions, Records, and Common Arkansas Tax Mistakes
Records to keep
- Invoices, 1099s, and bank and payment-platform statements
- Receipts and contractor payment records
- Mileage logs: date, destination, business purpose and annual total miles
- Home-office documentation
- Proof of every estimated payment
Open a separate business account. Mixed transactions are the fastest way to lose deductions.
Keep records for:
- Three years after filing in most cases
- Six years if you omitted more than 25% of gross income
- At least four years for employment records
Deductions worth researching
- Vehicle: 2026 business mileage is 72.5 cents per mile January through June and 76 cents July through December. Don't apply one rate to the whole year.
- Home office: The simplified method is $5 per square foot, up to 300 square feet. It requires regular, exclusive business use. Actual expenses go on Form 8829.
- Health insurance and retirement: These reduce income tax, not SE tax.
- Professional fees, software and advertising: These reduce Schedule C profit, so they cut both SE tax and income tax.
- QBI: A federal income-tax deduction only. From 2026, qualifying taxpayers with at least $1,000 of QBI may get a $400 minimum.
Common mistakes
- Reporting gross receipts as profit
- Treating the 1099 as your only taxable income
- Confusing Arkansas income tax with federal SE tax
- Skipping estimated payments, or using last year's rates and forms
- Misclassifying LLC income
- Overlooking separate obligations
Those separate obligations include:
- An Arkansas sales tax permit if you sell taxable goods or services
- Employer withholding registration (AR1R) if you hire
- An annual franchise tax report for registered LLCs
For 2026, the franchise tax report covers the year ended December 31, 2025, costs $150, and was due May 1, 2026. Federal disregarded-entity status does not cancel it.
Frequently Asked Questions
Does Arkansas have a state income tax?
Yes. The 2026 top individual rate is 3.7% under Act 2, with graduated rates below it. Check DFA's current guidance for your tax year and circumstances.
How do I pay Arkansas state taxes?
Use DFA's ATAP portal, mail a check or money order with the correct voucher, or pay by card for a fee. Choose the right tax type and period, and keep your confirmation.
How much is $100,000 a year after taxes in Arkansas?
There's no single answer. It depends on W-2 versus self-employment income, filing status, deductions, credits, and federal, state and SE taxes. Also, $100,000 in receipts isn't $100,000 of net profit. Use a current-year calculator or a tax professional.
Do self-employed people pay a separate Arkansas self-employment tax?
No separate Arkansas SE tax applies on top of the federal one. You pay federal SE tax for Social Security and Medicare, plus Arkansas income tax on your profit. Confirm treatment for your business structure and residency with DFA.
What forms do self-employed taxpayers file in Arkansas?
Forms vary by residency, entity type and income. Typical sole proprietors file federal Form 1040 with Schedules C and SE, plus AR1000F or AR1000NR. Verify the current Arkansas return and schedules with DFA.
When are estimated tax payments due in Arkansas?
Both federal and Arkansas estimates for 2026 are due April 15, June 15, September 15 and January 15, 2027. Confirm exact dates on the IRS and DFA calendars, since holidays and disaster relief can shift them.
