Real Estate Agent Tax Calculator
Estimate the tax on your commission income, then see what to reserve from each closing and each quarter.
Illustrative values are loaded. Replace them with your expected 2026 receipts and deductions. Nothing is saved.
Start with the way the brokerage pays you
This estimator supports commission activity reported on Schedule C. Entity treatment changes the tax calculation before any expense is entered.
Build the agent expense ledger
Enter deductible amounts you expect to document. Equipment cost, personal spending, commuting, and reimbursed expenses do not automatically belong here.
Place the commissions on the household return
Federal income tax is calculated by difference: the modeled household return with realtor profit versus the same return without it.
QBI and payment details (optional)
Use expected deductible amounts, not contribution goals or cash spending. The wage/property fields matter when taxable income crosses the 2026 QBI threshold.
2026 assumptions and primary sources
The model assumes a qualified licensed real estate agent taxed as a Schedule C sole proprietor or disregarded LLC, with no other self-employment activity. W-2 Boxes 1, 3 + 7, and 5 are entered separately because they serve different tax calculations. A prior QBI loss is applied in a simplified one-business carryforward model.
It does not model credits, capital-gain rates, AMT, NIIT, ACA premium-credit reconciliation, passive or rental losses, REPS, multiple-business QBI aggregation, complex itemized deductions, state sourcing, franchise taxes, or local taxes.
Educational estimate, updated August 30, 2026. Federal 2026 estimate for a Schedule C commission business. The optional state/local percentage is a user-chosen cash buffer, not a state-tax calculation. Confirm material decisions with a qualified tax professional.
Turn the estimate into a working reserve plan
The useful number is not a generic percentage. It is the amount left after the way your brokerage pays you, the expenses you can document, and the rest of your household return are all accounted for.
- STEP 01
Confirm the commission number
Use the amount paid to you or switch to GCI before the broker split. Never subtract the same split twice.
- STEP 02
Keep the two mileage totals
The IRS changed the business mileage rate on July 1, 2026, so one annual mileage total is not enough this year.
- STEP 03
Reconcile the payment target
Compare the cash reserve with the federal safe-harbor benchmark and adjust when closings arrive unevenly.
What the estimator does with each realtor input
The math follows a Schedule C commission business. Each line either changes net profit, self-employment tax, regular income tax, or the payment benchmark.
Swipe horizontally to compare
| Input | Treatment in this estimate | Why it changes the result |
|---|---|---|
| Broker or team split | Subtracted only in GCI-before-split mode | Prevents the most common double-counting error |
| Business mileage | 72.5¢ through June; 76¢ from July | Reduces Schedule C profit under the standard-mileage method |
| Agent expenses | Deducted from commission receipts | Reduces both income-tax and SE-tax bases when eligible |
| W-2 wage boxes | Box 1 sets taxable wages; Boxes 3 + 7 and Box 5 set payroll-tax bases | Keeps income tax, Social Security, and Medicare calculations separate |
| QBI inputs | Applies the 2026 threshold and wage/property limit | Avoids assuming the full 20% deduction at every income level |
| Eligible 2025 tax and AGI | Compared with 90% of modeled 2026 tax | Builds an estimated federal required-payment benchmark when the prior-year route qualifies |
Have the reserve pressure-tested before the next closing
A return-level review can catch S-Corp treatment, multi-state sourcing, other self-employment activity, credits, capital gains, and missed installment dates that a focused estimator cannot see.
Frequently asked questions
These answers describe the 2026 federal model used on this page. State and return-specific rules can change the final payment.
How much should a real estate agent set aside for taxes?
There is no reliable flat percentage for every agent. The right reserve depends on net profit after deductible expenses, other household income, W-2 wages, filing status, QBI limits, and state or local tax. This estimator calculates a federal reserve from those inputs and lets you add a separate planning buffer without presenting it as a state-tax calculation.
Are real estate commissions subject to self-employment tax?
Licensed real estate agents are treated as self-employed for federal tax purposes when substantially all compensation is tied to sales or other output and a written contract says they will not be treated as employees. In that case, positive net earnings generally face Social Security and Medicare tax in addition to regular income tax.
Should I enter GCI or the amount on my 1099-NEC?
Use the amount paid to you or expected on Form 1099-NEC in the default mode. If you instead enter gross commission income before the brokerage retained its share, switch to GCI mode and enter the retained split separately. Do not subtract the same broker split in both places.
What mileage rate does a Realtor use in 2026?
The 2026 business standard mileage rate is 72.5 cents per mile from January 1 through June 30 and 76 cents per mile from July 1 through December 31. Commuting is not business mileage, and the standard-mileage and actual-expense methods cannot both be used for the same vehicle and year.
Can a real estate agent claim the QBI deduction?
A real estate agent or broker is expressly excluded from the specified-service definition of brokerage services for Section 199A. Eligible profit can generate a QBI deduction, but taxable-income, W-2 wage, qualified-property, and carryforward limits still apply. This calculator models the 2026 income threshold and lets higher-income users add wage and property-basis inputs.
Is the quarterly amount an IRS safe harbor?
The reserve divided by four is only a cash-planning pace. The separate payment benchmark compares 90% of modeled 2026 federal tax with 100% of qualifying 2025 tax, or 110% when prior-year AGI exceeded $150,000. The prior-year route generally requires a return covering 12 months; a zero-tax exception also has full-year citizenship or residency conditions. Timing still matters, and agents with uneven commissions may need the annualized-income installment method.
Can I use this calculator for an S-Corporation?
No. S-Corporation officer wages, payroll tax, distributions, reasonable compensation, retirement contributions, and QBI are materially different. Choose S-Corporation in the calculator to see the stop state, then use the realtor S-Corp guide or book a return-level review.
