SEP IRA for Real Estate Agents: How to Shelter Big Commission Years From Tax
Why a SEP IRA Fits the Way Realtors Actually Earn
Real estate agents almost always file as sole proprietors on Schedule C or as single-member LLCs taxed the same way. Income lands in chunks. You close three deals in March and nothing in April. Predicting your top-line number on January 1 is a guessing game.
That is exactly the problem a SEP IRA solves. Under IRC Section 408(k), a Simplified Employee Pension lets you contribute up to 25% of your net self-employment income, with a 2026 dollar cap of roughly $70,000. The actual formula is closer to 20% of net SE income after the deduction for half of self-employment tax, but the point is you wait until you know the number before you write the check.
Setup is one form. IRS Form 5305-SEP is a one-page document you keep in your records. You don’t file it with the IRS. Open the account at any brokerage that offers SEP IRAs (Fidelity, Schwab, Vanguard all do it for free), fund it, deduct the contribution on your return, and you are done. No annual filings, no testing, no plan administrator.
Contribution Timing Is the Real Advantage
Most retirement accounts have a December 31 deadline. A SEP IRA does not. You can establish and fund a SEP IRA for the prior tax year all the way up to your tax-filing deadline, including extensions. File an extension to October 15 and you have nine and a half months after the year ends to figure out the right contribution amount.
That matters when your income is lumpy. An agent who had a slow first half and a monster fourth quarter doesn’t know until February or March what their actual Schedule C net income looks like. With a SEP IRA, that’s fine. Wait, run the numbers with your CPA, then fund the account before you file.
The other side of this is cash flow. If you owe a big tax bill anyway, the SEP IRA contribution reduces it. You’re effectively moving money from the IRS column to your retirement column, dollar for dollar at your marginal rate plus self-employment tax savings on the deductible side.
SEP IRA vs Solo 401(k) — Which One Lets You Save More
This is where most agents get the wrong answer. The 25% headline number makes SEP IRAs sound like the bigger plan. They are not, especially at moderate income levels.
A Solo 401(k) has two pieces. There’s an employee deferral (up to $24,500 in 2026, plus catch-up if you’re 50+), and then an employer profit-sharing contribution that works the same as a SEP, capped at 25% of net SE income. Add them together and the combined limit is the same $70,000-ish ceiling, but you hit it at a much lower income level.
Quick example. An agent with $100,000 of net SE income. SEP IRA contribution: roughly $18,500 (the 20% effective rate after SE tax adjustment). Solo $24,500 employee deferral plus the same $18,500 profit-sharing piece, total around $42,000. At that income level, the Solo 401(k) shelters more than double what a SEP IRA does.
The SEP IRA wins on simplicity. No annual Form 5500-EZ filing (Solo 401(k)s need one once assets exceed $250,000), no plan document beyond Form 5305-SEP, no separate Roth and traditional buckets to track. If your income is high enough that you’d max the 25% on its own — roughly $350,000 of net SE income — the difference between SEP and Solo 401(k) disappears at the contribution limit.
Below that threshold, Solo 401(k) usually wins. Above it, pick the one you’ll actually keep up with.
SEP IRA vs SIMPLE IRA — When the SIMPLE Wins
A SIMPLE IRA is the third option realtors should know about. The contribution limit is lower (around $16,500 in 2026 plus a $3,500 catch-up at 50+), but the math is more favorable at low income levels.
The reason: SIMPLE IRAs let you contribute a flat dollar amount plus a small employer match, not a percentage of income. An agent who netted $40,000 on Schedule C could contribute around $16,500 to a SIMPLE IRA plus a 3% match. The same agent’s SEP IRA contribution caps out around $7,400.
For most established agents the SIMPLE is the wrong call. The lower ceiling becomes binding fast. But for newer agents in their first year or two, or part-time agents with W-2 income on the side, a SIMPLE IRA sometimes shelters more dollars than a SEP. Worth running the numbers either way.
Spousal and Employee Implications
The biggest SEP IRA mistake we see at real estate agent practices involves employees. SEP IRA rules require that you contribute the same percentage of compensation for every eligible employee. If you contribute 20% of your own net SE income, you contribute 20% of every eligible employee’s W-2 wages too.
Eligible means: age 21 or older, worked for you in three of the last five years, and earned more than $750 in the current year (2026 threshold). An admin assistant you’ve paid for four years almost certainly qualifies.
This is where Solo 401(k) becomes the better choice. Solo 401(k) plans only allow the owner and the owner’s spouse to participate. If you employ anyone else, you’re disqualified from a Solo 401(k) and forced into either a SEP IRA (with the equal-percentage rule) or a more flexible plan like a SIMPLE IRA or 401(k) with automatic enrollment.
Married agents working as a team can each have their own SEP IRA if both have earned income. Two real estate agents in the same household with $200,000 each in net SE income can each contribute roughly $37,000 to their own SEP IRAs — about $74,000 combined into retirement accounts in a single year.
The Roth SEP Option Under SECURE 2.0
The SECURE 2.0 Act of 2022 added a Roth option to SEP IRAs starting in 2023. Before that, all SEP contributions were pre-tax only. Now you can elect to treat employer SEP contributions as Roth, meaning you pay tax on the contribution now but pull it out tax-free in retirement.
The mechanics are still rolling out at brokerage firms. Not every custodian offers Roth SEP yet, and the reporting on Form W-2 and the contribution mechanics differ from regular SEP contributions. Check with your account custodian before assuming the option is available.
For high-earning agents in their peak years, traditional SEP usually wins. You’re shifting income from a high-bracket year to (presumably) a lower-bracket retirement year. For younger agents earlier in their career, the Roth SEP can be the better long-term move.
Distribution Rules and RMDs
A SEP IRA follows traditional IRA distribution rules. Withdrawals before age 59 1/2 are subject to a 10% early withdrawal penalty plus ordinary income tax. Required minimum distributions start at age 73 under current law (rising to 75 in 2033 under SECURE 2.0).
You can roll a SEP IRA into a traditional IRA, a 401(k), or convert to a Roth IRA. The Roth conversion is a useful tool in a low-income year — an agent between deals, a year on maternity leave, the year after a market downturn. Convert when your bracket is low, pay the tax, and you’re done with future RMDs on that money.
Common Mistakes Realtors Make With SEP IRAs
Four mistakes account for most of the SEP IRA problems we see during tax season.
First: overcontributing. The 25% headline number is gross, not net of the SE tax adjustment. Real effective rate is closer to 20%. Agents who run the math wrong contribute too much, and the excess gets hit with a 6% excise tax every year it sits in the account.
Second: forgetting the formula uses net SE income, not gross commissions. Gross commissions less broker splits less business expenses less half of SE tax — that’s the base. A $400,000 gross commission year often translates to $200,000 of net SE income after splits and expenses.
Third: assuming you have to set up the SEP IRA by year-end. You don’t. Setup and contribution can both happen up to the extended filing deadline. Many agents miss out because they think December 31 was the cutoff.
Fourth: not coordinating with a Solo 401(k). You can’t easily run both at the same time without complications. Pick one, work it correctly, and move on. If you want to switch from SEP to Solo 401(k) for next year, do the switch in January.
This is the kind of detail our tax strategy consulting work catches before the return is filed, not after.

Frequently Asked Questions
Is a SEP IRA for real estate agents usually the right first retirement plan?
For a solo agent with no staff, it usually is. A SEP IRA for real estate agents is funded entirely by the business, which means there is no employee deferral, no payroll withholding and no annual plan return for most one-person arrangements. You adopt a short written plan document, often the model agreement the IRS publishes as Form 5305-SEP, open the account at a custodian and contribute when cash allows. Publication 560 is the plan by plan guide written for self-employed owners and it should be the first thing you read.
The contribution is a percentage of compensation rather than a flat amount you elect. For a common-law employee the ceiling is 25 percent of pay. For a sole proprietor the same rule works out to roughly 20 percent of net earnings after the adjustment described in the next answer, and the whole thing is also capped by an annual dollar limit the IRS updates each year. A very high earner hits the dollar cap before the percentage cap ever comes into play.
Timing is what makes this plan fit commission work. A SEP can be adopted and funded as late as the due date of the return including extensions. An agent who closes a large deal in November decides nothing in January and everything in March, once the profit figure is known. Compare that with a plan that requires a December election and the appeal becomes obvious for anyone whose income arrives in unpredictable blocks.
Two structural features are worth knowing before you sign anything. Contributions go into an ordinary individual retirement account opened for each participant, so the money belongs to that person immediately and there is no vesting schedule holding anyone in place. That cuts both ways for a team leader, because an assistant who resigns in November still keeps the full contribution made for that year. And since the account is an individual retirement arrangement rather than a qualified plan, no participant loans are available. Money you put in should be money you can afford to leave alone.
Put numbers on a solid year. An agent nets 150,000 dollars of profit after expenses. After the required adjustments the contribution lands near 27,900 dollars, deducted on Form 1040 as an adjustment to income rather than as a business expense. At a 24 percent federal marginal rate that removes about 6,700 dollars of income tax for the year, and the money is still yours, sitting in an account with your name on it rather than gone to a vendor.
Employees are the catch, and it is a real one. Every eligible employee has to receive the same percentage of pay that you give yourself. Eligible generally means age 21 or older, employed by you in three of the last five years and paid at least the small compensation floor the IRS sets. An agent who contributes 20 percent for herself and employs a licensed assistant who has been on payroll for four years at 55,000 dollars must also put 11,000 dollars into that assistant’s account. There is no way to give yourself a bigger percentage than the staff.
The mistake we see on team returns is assuming that everyone paid on Form 1099-NEC sits outside the plan automatically. Sometimes true, sometimes not. Worker classification turns on control and the working relationship rather than on which form you print, and the IRS employment tax guidance sets that standard. A team leader who reclassifies an assistant as an employee three years later inherits a plan problem alongside a payroll problem.
Get the staffing picture settled before adopting anything, because the plan that fits a solo agent is rarely the plan that fits a team of five. Clean payroll records and steady bookkeeping make that determination quick instead of painful. Decide the plan type in a year when you have time to think about it, and every future contribution becomes a routine calculation rather than a scramble.
How is the contribution computed on commission income?
The contribution base is where a SEP IRA for real estate agents goes wrong most often, and the error always runs the same direction. Agents compute the contribution on gross commissions. The correct base is net earnings from self-employment, which is a far smaller figure after the business has paid for itself and after two required adjustments most people have never heard of.
The sequence runs like this. Start with net profit from Schedule C, which is gross commissions minus brokerage splits, marketing, dues, vehicle costs and everything else the business spent. Reduce that by the deductible half of self-employment tax computed on Schedule SE. Then apply the self-employed rate, which is about 20 percent rather than 25 percent, because the contribution itself reduces the compensation figure it is measured against. That circularity is why the two rates differ, and the worksheet in Publication 560 handles it for you.
Here is a full worked case. An agent brings in 240,000 dollars of gross commissions and spends 90,000 dollars running the business, leaving 150,000 dollars of net profit. Net earnings subject to self-employment tax are 92.35 percent of that, or 138,525 dollars. Self-employment tax on that figure comes to roughly 21,200 dollars, so the deductible half is about 10,600 dollars. Subtract it and the adjusted base is 139,400 dollars. Twenty percent of that is 27,880 dollars, and that is the contribution.
Now the mistake, priced out. The same agent who applies 25 percent to the 240,000 dollars of gross commissions arrives at 60,000 dollars. That is more than double the allowed amount. An excess contribution does not sit quietly. It has to be withdrawn along with the earnings attributable to it, the earnings are taxable, and an excise tax can apply for every year the excess stays in the account. Fixing it costs professional time and it costs the compounding you thought you were buying.
Two ceilings sit above the percentage and both get missed. Only compensation up to an annual limit counts when the percentage is applied, so a very large profit stops producing contribution room at a set point. The total annual addition to the account is separately capped by a dollar figure the IRS adjusts each year. And in a year with no profit there is no contribution at all, because the base is net earnings rather than gross activity. An agent who had a strong first half and a loss for the full year contributes nothing, no matter how much money passed through the operating account.
Two structures change the arithmetic completely. If you run through a partnership, the base is your net earnings from self-employment as reported on the partnership schedule, not simply the ordinary income line. If you elected S corporation treatment and file Form 1120-S, there is no self-employment income at all. The base becomes your W-2 wages from the corporation, and the plan contribution is 25 percent of those wages, paid by the corporation. An agent who set a low salary to save payroll tax has quietly capped the retirement contribution at the same time, which is a trade worth pricing before you set the salary.
One more piece of the mechanics catches people. The deduction is an adjustment on the front of the individual return rather than a deduction on Schedule C. It lowers adjusted gross income and it lowers income tax. It does not reduce net profit, so it does not reduce self-employment tax by a single dollar. Agents who expect a contribution to cut the whole 15.3 percent layer are disappointed every spring, and the disappointment is avoidable with one conversation in advance.
Run the calculation from the tax return rather than from the bank statement. We build the contribution figure into the projection during tax strategy consulting so the number is known before the year closes rather than discovered in April. Get the base right once and the same worksheet serves you every year the business grows.
Would a solo 401(k) let me put away more than a SEP?
At moderate income, yes, and often by a wide margin. A solo 401(k) beats a SEP IRA for real estate agents in the middle of the earnings range because it has two contribution sources instead of one. You contribute as the employee through a salary deferral, and the business contributes on top as the employer. A SEP only has the employer half, so it needs a large profit figure to reach the same total.
Work the comparison at a realistic number. An agent nets 60,000 dollars of profit. After the self-employment tax adjustment the base is about 55,800 dollars, so the SEP contribution is roughly 11,160 dollars. Inside a solo 401(k) the same agent can defer, say, 20,000 dollars as the employee and then add the same 11,160 dollars as the employer, reaching just over 31,000 dollars. Nearly three times the SEP result on identical income. At much higher income the two plans converge, because a single overall annual additions ceiling applies to both.
The deferral also comes in a second flavor. Most solo 401(k) documents permit designated Roth deferrals, so an agent in a low income year can pay tax on the deferral now and take qualified withdrawals tax free later. A SEP has traditionally been pre-tax employer money only. For a newer agent whose income is temporarily low, paying tax at a low rate today is often the better long-run trade, and the plan type is what makes that choice available at all. Publication 590-A covers the contribution side of individual retirement arrangements and Publication 560 covers the employer plans.
Two more levers favor the 401(k) route. An agent who has reached age 50 can add a catch-up deferral on top of the ordinary limit, and there is no equivalent inside a SEP. A spouse who genuinely works in the business and takes compensation for it can defer as well, which nearly doubles the household total without bringing in an outside employee. Both of those exist only because the plan has an employee side, and both get left out of the quick comparisons agents read online.
Nothing is free. A solo 401(k) needs a real plan document, and once plan assets pass 250,000 dollars an annual information return is due. Timing is stricter as well. As a general matter the plan has to exist before the year ends for an employee deferral to be possible, with a narrow rule that lets a sole proprietor adopt a first-year plan and make the deferral by the filing deadline. The employer piece can still go in as late as the extended due date. A SEP has none of that complexity, and for an agent who values a five minute setup, simplicity has real value.
The word solo is a hard requirement rather than marketing. The plan works only if the business has no common-law employees other than a spouse. Hire one licensed assistant on payroll and the plan stops being a solo arrangement, which means coverage testing, a different plan document and a much larger administrative bill. Agents who plan to build a team inside two years should think carefully before choosing this route.
The mistake we correct most often is timing. An agent calls in March wanting to open a solo 401(k) and defer for the prior year, having hired a full-time assistant the previous August. Both facts are fatal in the same conversation. Decide the plan in the fall, sign the documents before the end of December and the deferral is available when you need it.
One practical middle path exists. An agent can keep a SEP for its simplicity while income is modest, then move to a solo 401(k) in a year when the deferral would add real dollars. The accounts can coexist and old SEP balances do not have to be disturbed. Look at the choice again every year your production changes, because the plan that fit at 60,000 dollars of profit is rarely the plan that fits at 200,000 dollars.
Where do a SIMPLE IRA and a personal Roth account fit in?
A SIMPLE IRA sits between the SEP and the 401(k), and it earns its place on a team. Any business with 100 or fewer employees can adopt one. Staff contribute through salary deferrals and the employer either matches deferrals up to about 3 percent of pay or makes a 2 percent contribution for everyone eligible. The deferral ceiling is lower than a 401(k) allows, and the plan has to be established by October 1 to cover the current year.
The reason a team leader looks at this plan is cost. Under a SEP, giving yourself 20 percent forces 20 percent for every eligible employee. A brokerage team with 180,000 dollars of staff payroll would owe 36,000 dollars in employer contributions to reach a 20 percent owner contribution. Under a SIMPLE IRA with a 3 percent match, the employer cost on that same payroll is about 5,400 dollars, and only for staff who actually defer. The owner contributes less than a SEP would allow, but keeps far more of the cash. Publication 560 lays the plan types side by side.
That plan carries a trap on the way out. Money withdrawn within the first two years of participation carries an additional 25 percent tax rather than the usual 10 percent, and during that same window the balance can generally only be rolled into another account of the same type. An agent who adopts one in October, changes course the following spring and moves the money has created a tax bill that a short wait would have avoided entirely. Write the two year date somewhere you will actually look at it.
Personal accounts sit in a separate bucket and stack on top. A traditional or Roth individual retirement arrangement is funded with your own money and is not part of the business plan at all. Contribution limits are set annually and the deadline is the unextended April filing date, with no extension available. Publication 590-A handles contributions and Publication 590-B handles what happens when money comes out.
Here is the interaction agents miss. Once you are covered by a workplace plan, and a SEP counts as coverage for this purpose, the deduction for a traditional individual retirement contribution phases out at a modest income level. A Roth contribution has its own separate income phase-out that has nothing to do with plan coverage. So an agent with a funded SEP may still contribute to a traditional account and simply get no deduction for it, which creates after-tax basis that has to be tracked on the return for decades.
Price the error. An agent contributes 7,000 dollars to a traditional account in monthly pieces across the year, then funds a 27,900 dollar SEP in March. The traditional contribution turns out to be fully nondeductible because of plan coverage and income. Nothing illegal happened and no penalty applies, but the agent expected roughly 1,680 dollars of tax benefit at a 24 percent rate and received none. Worse, the basis often goes untracked, and years later the withdrawal gets taxed a second time because nobody kept the record.
Distributions carry their own rules and they matter more than people expect at the outset. Money taken from any of these accounts before age 59 and a half is generally taxable and carries an additional 10 percent tax unless an exception applies. An agent who funds a plan heavily in a strong year and then raids it during a slow one has paid for the privilege twice. Build a separate emergency reserve outside the retirement account so the plan never becomes the fallback.
Sequence the accounts rather than funding whichever one is easiest to open. Look at the business plan first because it holds the larger numbers, then decide whether a personal Roth still fits under the income limits. Reviewing this alongside your individual tax return each year keeps the coverage and phase-out questions from surprising you. Set the order once and the annual decision takes minutes.
How do I fund a plan when commission income arrives in lumps?
Funding a SEP IRA for real estate agents in a commission year is a cash flow problem before it is a tax problem. Income arrives in blocks with long gaps between them, and the contribution deadline falls months after the year closes, which is exactly when an agent has the least visibility into the coming spring. The fix is mechanical rather than clever. Hold money back from each commission check as it lands.
Set a percentage and route it automatically. An agent expecting 240,000 dollars of gross commissions and a 27,880 dollar contribution needs to reserve about 12 percent of each gross check. On a 9,000 dollar commission that is 1,080 dollars moved the day it clears, into a separate account that sits next to the tax reserve rather than inside it. Two separate buckets, because one of them is money you owe and the other is money you are choosing to save. Agents who combine the buckets spend the retirement money on the tax bill every single year.
The extension gives you room and also gives you rope. Because a SEP can be funded up to the extended due date of the return, an agent can file an extension, watch the spring close and decide in September. That flexibility is real, and so is the risk. A missed deadline cannot be cured. There is no late contribution, no amended return that fixes it and no relief provision waiting. The year is simply gone. Put the funding date on a calendar the moment the extension is filed.
Build the contribution into your quarterly payments rather than treating it as a surprise. A planned 27,880 dollar contribution reduces taxable income before the estimated tax vouchers get computed, which means smaller payments through the year and a smaller refund sitting at the IRS. The estimated tax rules do not care that your income is lumpy, and an agent whose fourth quarter carries most of the year can look at the annualized income method to line the payments up with reality.
Remember what the contribution does and does not do. At a 24 percent marginal rate, that 27,880 dollars removes about 6,700 dollars of federal income tax. The self-employment tax figure on Schedule SE does not move at all, because the deduction lands on the front of the individual return rather than inside the business. Plan around the number you will actually keep, not the headline percentage.
Keep a short file and the reporting takes care of itself. Hold the signed plan document, the worksheet showing how the contribution was computed for the year, the annual statement the custodian files with the IRS and the deposit confirmation. Check that custodian statement carefully. A contribution made in March for the prior year is routinely coded to the wrong plan year, and the mismatch surfaces as a notice long after everyone has forgotten the transfer. Confirm the plan year on the deposit ticket at the moment you make it.
One boundary belongs in plain language. The Reed Corporation is a CPA and tax firm. We are not a registered investment adviser. We do not sell or manage retirement products and we do not recommend the investments held inside a plan. Our work is the tax side, meaning the allowable contribution figure, the plan type that fits your tax picture, the deadlines and the reporting, done in coordination with your own licensed advisor and the plan custodian who handle the investment decisions. Agents who want that coordination set up before year end can Request Private Consultation and bring the current profit figure.
The mistake that costs the most is waiting for a perfect year to start. Agents skip three modest years hoping to make one large contribution later, and the compounding lost in those early years never comes back. These are federal rules and state treatment of the deduction varies, so our clients in Austin, Chicago, Los Angeles, Miami and New York City each see a different state result on top. Start the transfer habit with the next commission check and the funding question answers itself by March.
