Taxes for Illinois Real Estate Agents: 1099 and SE Tax

The IRS treats licensed real estate agents as statutory nonemployees, so commissions are normally reported on a Form 1099-NEC, not a W-2, and that single fact moves the whole tax bill onto the agent. The IRS names licensed real estate agents as statutory nonemployees, which means they are treated as self-employed for income tax and for employment taxes, and self-employment tax at 15.3 percent applies to 92.35 percent of what they net from the business.

This guide explains the federal rules in plain terms, from the IRS's own pages, and points to the Illinois rule that sits next to them. It is not tax advice, and a licensed CPA or enrolled agent is the person who applies these rules to your numbers. Gambino Realtors has been in business in Rockford since 1923, and the tax side of an independent contractor career is one of the things a new agent should understand before choosing a brokerage. Our article on what real estate agents make in Illinois covers the income side. Our guide on how to choose your first brokerage covers the other questions to ask before signing.

Why You Receive A 1099 And Not A Paycheck

The starting point is a section of the tax rules that most new agents never read. A licensed real estate agent in that category is treated as self-employed for all federal tax purposes, including income taxes and employment taxes. Two conditions have to be met.

The first is that substantially all of the payments for the agent's services are directly related to sales or other output, rather than to the number of hours worked. A commission fits that description. An hourly wage does not. The second is that the services are performed under a written contract that says the agent will not be treated as an employee for federal tax purposes.

That written contract has a counterpart in Illinois licensing law. Under 68 Ill. Adm. Code 1450.735, every sponsoring broker must have a written employment or independent contractor agreement with each sponsored licensee. The agreement has to be dated and signed by both sides, and it has to cover at least the terms of the relationship, the supervision required by the Real Estate License Act, the licensee's duties, compensation, duration, and how the agreement ends. The sponsoring broker must give each licensee a copy of the fully signed agreement and any changes to it. The rule also says that when a written agreement provides for an independent contractor relationship that clearly establishes it, the specific provisions of the Act control for the licensee's conduct of brokerage activities. So the licensing rule and the tax rule both start from the same piece of paper.

Read it with both purposes in mind. The licensing rule tells you what the agreement must contain. The tax rule tells you what it must say about employee status. If you are unsure whether your own arrangement fits, the IRS offers Form SS-8, which either the business or the worker can file to ask the IRS to decide a worker's status. The IRS notes that a determination can take at least six months, so it is a tool for a real dispute and not a quick check.

Outside the statutory category, the IRS uses a common-law test with three groups of facts. Behavioral facts ask whether the company controls what the worker does and how. Relationship facts ask about written contracts, benefits, and whether the work is a key part of the business. The IRS states that no set number of factors decides the question and that the whole relationship has to be considered. For a licensed agent paid by commission under a written independent contractor agreement, the statutory rule is the one that applies, but the test is a useful way to read the rest of your brokerage agreement.

What does the label change? The IRS says that, generally, a business does not have to withhold or pay taxes on payments to independent contractors. That is the whole difference in one line. No one takes income tax, Social Security, or Medicare out of a commission check for you. The tax is still owed. You are the one who calculates it and pays it, which is why the rest of this article is about the paperwork and the payment schedule.

The 1099-NEC, Self-Employment Tax And Quarterly Payments

Start with the form. Form 1099-NEC reports nonemployee compensation, and the IRS instructions say that fees and commissions for services performed by someone who is not an employee are included. For tax years beginning after 2025, the minimum amount that triggers the form is 2,000 dollars, and the IRS says that figure may be adjusted for inflation starting in calendar year 2027. The payer must furnish the form to the recipient and file it with the IRS by January 31. For commissions earned in 2026, that means a form due by January 31, 2027.

The 1099-NEC is the report of what you were paid. The tax return is where you turn it into a business result. A sole proprietor reports business income and expenses on Schedule C, which the IRS describes as the form for income or loss from a business you operated as a sole proprietor. The IRS says an activity counts as a business if the primary purpose is income or profit and you are involved with continuity and regularity. Amounts shown in box 1 of a Form 1099-NEC are business income. The net result on Schedule C then feeds the self-employment tax calculation.

Self-employment tax is the part that surprises people, because it is a second tax on top of income tax. The IRS Topic 554 page explains it this way. If you are a sole proprietor, including an independent contractor, you usually must pay self-employment tax once your net earnings from self-employment reach 400 dollars. The amount subject to the tax is generally 92.35 percent of your net earnings. You get to net earnings by subtracting ordinary and necessary business expenses from the gross income of the business. The rate is 12.4 percent for Social Security and 2.9 percent for Medicare, which is the 15.3 percent total mentioned above.

Here is the arithmetic, using a round number chosen only to show the steps. It is an illustration of the rule and not a forecast of anything. Suppose a sole proprietor ends the year with net earnings of 40,000 dollars on Schedule C. Multiply by 0.9235 and the amount subject to self-employment tax is 36,940 dollars. Multiply that by 0.153 and the self-employment tax is about 5,652 dollars. The IRS then lets you deduct one-half of the self-employment tax when you figure your adjusted gross income, which in this example is about 2,826 dollars. You calculate that deduction on Schedule SE. The deduction lowers your income tax. It does not lower the self-employment tax itself.

Two limits are worth knowing. The Social Security part applies only up to a maximum amount of net earnings that the law sets and that changes every year, so check the current figure on the IRS page. All net earnings are subject to the Medicare part. On top of that, an Additional Medicare tax applies to self-employment income above thresholds of 250,000 dollars for a married individual filing jointly, 125,000 dollars for a married individual filing separately, and 200,000 dollars for everyone else.

Now the payment schedule. Because nothing is withheld from commissions, the IRS expects tax to be paid as you earn it. The IRS estimated tax page says that if you are in business for yourself you generally need to make estimated tax payments, and that estimated tax covers income tax and other taxes such as self-employment tax. Individuals, including sole proprietors, generally have to make estimated payments if they expect to owe 1,000 dollars or more in tax when the return is filed. You figure the amount on Form 1040-ES, and the IRS suggests using your prior year's return as a starting point.

The year is divided into four payment periods. IRS Publication 505 lists the 2026 due dates as follows.

• April 15, 2026, for income received January 1 through March 31.
• June 15, 2026, for income received April 1 through May 31.
• September 15, 2026, for income received June 1 through August 31.
• January 15, 2027, for income received September 1 through December 31.

If a due date falls on a Saturday, Sunday, or legal holiday, the payment is on time if made the next day that is not one of those. Publication 505 also says that if you file your 2026 Form 1040 by January 31, 2027 and pay the rest of the tax you owe, you do not need to make the January 15 payment. You can pay by mail with Form 1040-ES, online, by phone, through the IRS app, or through your IRS online account. The IRS also says you may pay weekly or monthly if that is easier, as long as you have paid enough by the end of each quarter.

Underpayment carries a penalty, and the IRS says it can apply even if a refund is due when you file. The IRS states that most taxpayers avoid the penalty if they owe less than 1,000 dollars after subtracting withholding and credits, or if they paid at least 90 percent of the current year's tax or 100 percent of the prior year's tax shown on the return, whichever is smaller. Publication 505 adds a variation. If your adjusted gross income for the prior year was more than 150,000 dollars, or 75,000 dollars for married filing separately, the prior-year figure becomes 110 percent instead of 100 percent.

Commission income does not arrive evenly. An agent can have a quiet spring and a crowded autumn. The IRS addresses this directly. If your income is received unevenly during the year, you may be able to avoid or lower the penalty by annualizing your income and making unequal payments, and Form 2210 is how you check. Ask your CPA whether it fits your pattern.

Illinois has its own parallel requirement. The Illinois Department of Revenue states in its Publication 105 that you must make estimated payments if you reasonably expect your Illinois tax liability to exceed 1,000 dollars after Illinois withholding, pass-through withholding payments, and credits. For individuals the dates are April 15, June 15, September 15, and January 15 of the following year, on Form IL-1040-ES. The federal and state dates match, but the amounts are figured separately, so a CPA should set up both.

What You Can Deduct And What To Keep

The self-employment tax is figured on net earnings, so what counts as a business expense changes the bill directly. The IRS test, in Publication 334, is that a business expense must be both ordinary and necessary. An ordinary expense is one that is common and accepted in your field of business. A necessary expense is one that is helpful and appropriate for your business, and it does not have to be indispensable. If an expense is partly for business and partly personal, you separate the personal part, and the personal part is generally not deductible.

The IRS pages on this topic do not publish a list written specifically for real estate agents, so this article does not give one. What follows are the categories the IRS describes in general terms, each of which a CPA can match to your actual spending.

If you use your car for both business and personal purposes, you may deduct only the cost of the business use. You can generally figure the deduction by the standard mileage rate or by actual expenses. For a car you own, you have to choose the standard mileage rate in the first year the car is available for business use, and after that you can pick either method. Parking fees and tolls for business use are deductible separately under either method. The IRS also says you cannot deduct the cost of driving between your home and your main or regular workplace, because that is personal commuting. Local transportation that does qualify includes visiting clients and going to a business meeting away from your regular workplace. If your home office qualifies as your principal place of business, then your home can be the workplace for this purpose, which is why the home office rules and the mileage rules need to be read together.

The home office rules are strict. The IRS says the part of the home must be used exclusively and regularly as your principal place of business or as a place where you meet or deal with clients in the normal course of your business. A room used both for business and for personal purposes does not qualify. A home can still be your principal place of business if you use it for administrative or management activities and have no other fixed location where you conduct substantial administrative or management work. You can figure the deduction by the regular method or by the simplified option..

Professional help is its own category. The IRS says legal and professional fees, such as fees charged by accountants, are deductible on Schedule C when they are ordinary and necessary and directly related to operating the business. The cost of preparing the business part of your tax return is deductible as well.

The other half of a deduction is proof. The IRS requires that you substantiate your expenses by adequate records or by sufficient evidence to support your own statement. The recordkeeping page explains that records should support every item of income, deduction, and credit, and that you generally keep them until the period of limitations for that return expires. That period is generally three years from the date you filed. It is six years if you leave out more than 25 percent of the gross income shown on the return. The IRS says there is no required bookkeeping method, but the method you use has to clearly and accurately reflect your gross income and expenses. Publication 334 suggests keeping a separate bank account for the business, which is a simple habit that makes the line between business and personal spending much easier to draw.

One practical consequence follows from all of this. The better time to set a method is in the first month of the license, and the same goes for a part-time start, which our guide to part-time real estate work in Illinois covers, when the first commission is still ahead. Put the self-employment tax and the income tax on a plan, open the separate account, start the mileage record, and book a short meeting with a CPA. None of these steps require expertise. They only require starting before the first check arrives.

The Bottom Line

An Illinois agent paid by commission under a written independent contractor agreement is treated by the IRS as self-employed. That means a 1099-NEC instead of a W-2, self-employment tax of 15.3 percent on 92.35 percent of net earnings, and estimated payments on April 15, June 15, September 15, and January 15 for federal tax, with matching dates for Illinois. The rules are not complicated, but they are unforgiving about timing, and they put the work of paying the tax on you. What reduces the bill is documented ordinary and necessary expenses, not guesswork. Hire a CPA early, keep records from the first day, and read the written agreement before you sign it. Insurance is another cost to plan for, and our guide to errors and omissions insurance for Illinois brokers explains it. When you compare brokerages, use our guide on how to choose your first brokerage as the list of questions, and add one more of your own about how and when you are paid.

That covers the rules in the order they reach you. These are questions a new agent is likely to have about the tax side of the first year.
