Important Stuff Upfront
- Almost every agent is an independent contractor, so commission income is self-employment income: you owe the 15.3% self-employment tax on top of regular income tax, and nobody withholds it for you.
- Your brokerage reports your split, not the gross commission. Tax is figured on your net profit after deductions, so tracking expenses all year is what shrinks the bill.
- The biggest write-off for most agents is the car. Log every business mile: the 2026 standard mileage rate is 72.5 cents per mile.
- Commissions arrive in lumps. Set aside a share of every check and pay quarterly estimated taxes so April is not a shock.
A closing check feels like a paycheck, but the IRS does not treat it like one. When you got that commission, no employer set aside taxes, no Social Security or Medicare was deducted and no year-end withholding was quietly happening in the background. All of that is now your job. Agents who understand this early keep more of what they earn and skip the March panic. This guide walks through how commission income is taxed, the deductions agents most often leave on the table, and the mistakes that turn a good year into a scary tax bill. It is educational, not tax advice, so treat it as a map rather than a filed return.
How real estate commissions are taxed
If you hang your license with a brokerage as an independent contractor, and the large majority of agents do, your brokerage sends you a Form 1099-NEC in January showing what it paid you for the year. That figure is your split, after the house takes its cut, not the full commission on the sale. You report it on Schedule C, subtract your business expenses and the leftover net profit is what gets taxed.
That net profit gets hit twice. First comes the self-employment tax: 15.3% (12.4% for Social Security up to the annual wage base, plus 2.9% for Medicare) on 92.35% of your net profit. This is the piece a salaried employee never sees directly, because their employer pays half. As your own boss, you pay both halves. Then your net profit also flows into your regular federal income tax, stacked on any other household income. The two layers together are why an agent's effective tax rate often lands in the low-to-mid 20s once profit is healthy.
If you were a W-2 employee
Your employer withholds income tax from each check and pays half of your Social Security and Medicare (7.65%). You see a refund or a small balance at filing, and quarterly payments are not your problem.
As a 1099 agent
Nothing is withheld. You owe the full 15.3% self-employment tax plus income tax, and you send it yourself in four estimated payments across the year. The upside: your business deductions are yours to claim.
Curious what the numbers look like for your own commission income? The real estate agent tax calculator estimates the self-employment and income tax on a net profit figure in a few seconds, and the quarterly taxes guide covers how to split that into the four payments.
Worked Example: Marcus Runs the Numbers
Marcus is a solo agent, single, with no other job. He closed enough deals to earn a solid year and tracked his expenses in a spreadsheet.
- Commission income on his 1099-NEC (his split): $95,000
- Business expenses (MLS and board dues, marketing, vehicle, E&O insurance, desk fees): $23,000
- Net profit (Schedule C): $72,000
- SE taxable base ($72,000 × 0.9235): $66,492
- Self-employment tax ($66,492 × 15.3%): $10,173
- SE tax deduction (half of the SE tax): $5,087
- Taxable income after the SE deduction and a $15,000 standard deduction (single, 2026 estimated): $51,913
- Estimated federal income tax (2026 brackets, single): ~$6,300
- Total federal bill: ~$16,500
Five mistakes real estate agents make at tax time
The commission math is the easy part. Most of the pain comes from a handful of avoidable habits. Here are the ones that show up again and again.
1. Spending the whole commission check
The fix
A $9,000 commission is not $9,000 of spending money. The moment a check clears, move a set percentage (many agents use 25% to 30%) into a separate savings account earmarked for taxes. You never miss money you never saw in your checking account.
2. Skipping quarterly estimated payments
The fix
The IRS wants its money through the year, not in one April lump. Miss the quarterly deadlines and you can owe an underpayment penalty even if you pay in full at filing. Send estimates on the four due dates (roughly April, June, September and January) using IRS Direct Pay.
3. Not tracking business mileage
The fix
Agents live in their cars: showings, listing appointments, inspections, closings. Miles you cannot document are miles you cannot deduct. A mileage app that logs trips automatically is worth its small cost many times over, as the example below shows.
4. Treating the commute as deductible
The fix
Driving from home to your regular brokerage office is generally a personal commute, not a business mile. Trips to a showing, a client meeting or a property are business miles. A qualifying home office can change the math, so keep the two categories clearly separated in your log.
5. Mixing personal and business money
The fix
One business checking account and one business card make deductions obvious and audits painless. When your MLS dues and staging costs run through the same card as your groceries, real write-offs get lost and the ones you do claim are harder to prove.
Do not guess your mileage: track it
Because agents drive so much, the vehicle deduction is usually the single largest line on the return. You can claim it two ways: the standard mileage rate (72.5 cents per business mile for 2026, per IRS Notice 2026-10) or the actual-expense method (the business-use share of gas, insurance, repairs, depreciation and the rest). You pick one, but either way you need a mileage log. Without the miles, you cannot use the standard rate and you cannot calculate the business-use percentage for the actual method.
Worked Example: The Cost of a Missing Mileage Log
Renata drives 14,000 business miles showing homes and meeting clients across her market.
- Business miles logged: 14,000
- Standard mileage deduction (14,000 × $0.725): $10,150
- Her combined marginal rate (22% income tax + the SE tax effect): roughly 30%
- Tax saved by claiming those miles: ~$3,000

Estimate My Taxes →Deductions agents leave on the table
Beyond the car, agents run a business full of ordinary and necessary expenses that reduce taxable profit. Common ones worth tracking: MLS access and local board or association dues, your license renewal and continuing education, errors and omissions (E&O) insurance, brokerage desk fees and transaction fees, marketing (signs, photography, staging, mailers, paid ads and your website), lockbox fees, client closing gifts (within the annual limit the IRS sets), business use of your phone and internet, and software for your CRM and e-signature tools. If you keep a qualifying home office used regularly and only for your business, that can be deductible too, and the freelancer's guide to business deductions walks through how to document these so they hold up.
The pattern is simple: if you spent it to run your real estate business and you can prove it, it probably reduces your tax. If you cannot prove it, assume you cannot claim it. That is why the record-keeping habits matter more than knowing any single rule.
Managing income that arrives in lumps
The hardest part of agent finances is not the tax rate, it is the timing. You might close three deals in a month and then nothing for six weeks. When money is flush it is tempting to spend to your best month, then scramble when a quarterly payment lands during a dry spell. A steadier approach: on every commission check, split it the moment it clears. A common rule of thumb is roughly 25% to 30% to the tax account, a slice to a business buffer that smooths the slow months, and the rest to yourself. Fund the tax account first and the quarterly deadlines stop being stressful, because the money is already sitting there.
Two more habits make lumpy income manageable. Keep a rolling estimate of your year-to-date net profit so you can adjust your quarterly payments as the year develops, and revisit it mid-year rather than guessing in December. And if your net profit climbs into the high five figures and stays there, it may be worth asking a tax professional whether an S-corp election could reduce your self-employment tax, since that decision depends on numbers specific to you.
Build the system before your next closing
Real estate rewards agents who treat the business side as seriously as the sales side. A separate tax account, a mileage app running in the background, one business card and a quarterly payment on the calendar will save you more stress than any single deduction. Set those up before your next check clears and tax season becomes a formality instead of an emergency. When your situation gets complex, a CPA or enrolled agent who works with agents can tailor these ideas to your market and your numbers, and this site is a good place to run the estimates before that conversation.
