Frequently asked questions

Do I pay state income tax on side hustle income in Arkansas?
Yes. Arkansas taxes self-employment and side hustle profit as ordinary income, with a top marginal rate of 3.9% in 2026. It stacks on top of federal self-employment tax (15.3%) and federal income tax. The calculator above estimates your Arkansas tax using 2026 single-filer brackets; it excludes the state standard deduction, so treat it as a slightly conservative figure.
How much should I set aside for taxes on a side hustle in Arkansas?
A practical rule for Arkansas side hustlers: set aside 25–30% of net profit for federal taxes (self-employment tax plus income tax), then add roughly your Arkansas marginal rate on top. Pay federal quarterly estimates via Form 1040-ES and check whether Arkansas also requires quarterly state estimates.
When are Arkansas estimated tax payments due?
Arkansas follows the federal schedule: state estimated payments are due April 15, June 15, September 15, and January 15 of the following year, the same days as your IRS payments. Payments go to the Arkansas Department of Finance and Administration. The federal IRS schedule (April 15, June 15, September 15, January 15) applies separately.
How does the side hustle calculator work?
Enter each income stream separately — Etsy, freelance clients, DoorDash, whatever you run. For each hustle you enter your monthly gross income (or hourly rate), monthly business expenses, and monthly business miles driven. The calculator annualizes everything, then deducts expenses and the IRS standard mileage rate ($0.725/mile for 2026 per Notice 2026-10), computes self-employment tax (15.3% on 92.35% of net profit), and optionally estimates your state income tax using 2026 single-filer brackets.
Why can't I enter gas and miles at the same time?
The IRS requires you to pick one method: the standard mileage rate OR actual vehicle expenses (gas, oil, depreciation). The $0.725/mile standard rate already covers gas and maintenance, so deducting gas separately on top of it would be double-counting — and the IRS would disallow it on audit. Enter miles for the mileage deduction, and put non-vehicle expenses (software, supplies, platform fees) in the expenses field.
Does the calculator include federal income tax?
Yes. Pick your filing status and enter your other annual income (such as a day job), and the calculator estimates the federal income tax on your side-hustle profit using 2026 brackets and the standard deduction. It does this incrementally — the tax on your other income plus the profit, minus the tax on your other income alone — so your profit is taxed at the correct marginal bracket on top of what you already earn. Self-employment tax (15.3%) and the half-SE-tax deduction are handled too. It doesn't model itemized deductions, credits, or dependents, so treat it as a close estimate, not a filed return.
How accurate is the state tax estimate?
It's a directional estimate, not a precise filing number. The calculator applies 2026 single-filer brackets to your net profit minus half of your SE tax deduction. It does not model state standard deductions, personal exemptions, local income taxes (e.g. NYC adds up to 3.876%), or other state-specific rules. Treat it as a floor — your actual state tax at filing will likely be somewhat lower once your CPA applies all applicable deductions. States like California, New York, Oregon, and Minnesota are high; Florida, Texas, Nevada, and Washington have no state income tax.
Why does the calculator use $0.725/mile instead of $0.67?
The IRS raised the standard mileage rate to $0.725 per mile for 2026 (up 2.5 cents from $0.700 in 2025), per IRS Notice 2026-10. Some older calculators still show the outdated $0.67 rate from 2024. Using the wrong rate understates your deduction and overstates your tax bill.
I have multiple income streams — how do I add them all?
Click '+ Add another hustle' to add a panel for each income source. The calculator separately tracks gross income, expenses, and mileage per hustle, then combines everything for the SE tax and state tax calculation. SE tax is computed on your total net profit (not per hustle) because it's assessed on your combined Schedule C income at filing.
Do I need to pay quarterly taxes on side hustle income?
Yes, if you expect to owe more than $1,000 in federal taxes for the year after withholding from any W-2 job. The IRS expects quarterly estimated payments (Form 1040-ES) roughly on April 15, June 15, September 15, and January 15. A rough rule of thumb: set aside 25–30% of every net profit dollar for federal taxes, plus your state rate, and make quarterly payments.
