Business mileage or actual vehicle costs
Track client showings, listing visits and other business trips with contemporaneous records; commuting is different.
Commission income can be uneven and large, so real estate agents benefit from reserving tax when each commission is received. The right percentage depends on annual profit, business expenses, state, other wages and withholding—not on the size of one closing.
Start with three numbers. Use the full calculator when you need W-2 wages, withholding, health insurance or safe-harbor planning.
Baseline scope: single filer, one sole-proprietor business, standard deduction, no W-2 wages or withholding in this mini calculator.

Real estate income often arrives in bursts while business costs continue every month. A percentage-based reserve can work well operationally, but it should be recalculated when annual commissions change. Mileage, MLS and association costs, marketing, signs, photography, software and broker-related fees can materially reduce business profit.
The IRS says gig-economy income is taxable even when the work is part-time, temporary or not reported on an information return. Use the forms you receive to reconcile your records, but base the tax estimate on the complete business activity required by the tax rules.
These are categories to review, not automatic deductions. A cost still needs to meet the tax rules and be supported by records.

Business-related memberships, MLS access and licensing costs may be relevant.
Photography, signs, print materials, digital ads and website costs can be ordinary business expenses.
CRM, transaction tools and business-use phone costs can reduce profit.
Keep closing statements and brokerage records showing fees connected to commissions.
Real estate commissions are uneven, so the tax reserve should be recalculated as annual profit changes. The mini calculator estimates the current percentage using gross commission income, business expenses and state, then shows how much of each $1,000 of revenue the model suggests reserving.
Use a percentage tied to expected full-year profit, not the size of one closing. A large commission can move more income into higher tax brackets, while deductible business costs can reduce the profit subject to tax.
Mileage or vehicle costs, MLS and association fees, licensing, listing photography, signs, advertising, CRM software, business-use phone costs and broker or transaction fees are common categories to review and document.
Operationally, moving the modeled reserve from each commission into a separate tax account can make uneven income easier to manage. Recalculate after unusually large closings or major changes in annual expenses.
Use the mileage deduction calculator for documented business driving and the quarterly tax calculator when you need to estimate the next payment rather than the savings reserve.
Self-employed 1099 workers may need estimated payments during the year. The amount to save and the amount to send this quarter are separate questions. If you also have a W-2 job, payroll withholding can affect how much tax remains unfunded.
The IRS states that gig-economy income is taxable even if no Form 1099-K, 1099-NEC or other information return is issued. Keep your own income and expense records and reconcile them to any forms you receive.
The mini calculator uses the same documented 2026 planning engine as Analyze My Income's main 1099 tools. It starts with gross 1099 income, subtracts the business expenses you enter, estimates self-employment tax, federal income tax and the selected state income-tax path, then expresses modeled taxes as a share of gross 1099 revenue. The full calculator can also account for W-2 wages, withholding, health insurance and payments already made.
Your profession changes common expenses; your state changes the individual-income-tax layer. Pick a state calculator to keep those two questions separate.
