Small Business Exemption 25M Gross Receipts: 2026 Guide for Real Estate Investors

The small business exemption 25M gross receipts threshold is one of the most powerful — and overlooked — tax tools available to real estate investors in 2026. If your average annual gross receipts stay below $25 million, the IRS lets you simplify your accounting, deduct more mortgage interest, and skip complex inventory rules. Understanding this exemption can save real estate investors thousands of dollars every tax year. Learn how to qualify and use it with our real estate tax strategy resources.

Key Takeaways

• The small business exemption 25M gross receipts threshold allows qualifying real estate businesses to use the cash method of accounting in 2026.
• Businesses under the $25 million threshold are exempt from the Section 163(j) business interest limitation — meaning you can deduct all mortgage interest.
• The One Big Beautiful Bill Act (OBBBA), signed in 2025, reinforced and extended key provisions that benefit small real estate businesses in 2026.
• Gross receipts are calculated as a three-year average — you must test all entities under common control together.
• Exceeding the threshold triggers new accounting obligations — but careful entity structuring can keep you below the limit.

What Is the Small Business Exemption 25M Gross Receipts?

The small business exemption 25M gross receipts threshold is found in several sections of the Internal Revenue Code. It serves as a bright-line test. If your business earns less than $25 million on average over the prior three tax years, you qualify for a set of important tax simplifications. These simplifications touch accounting methods, interest deductions, and inventory rules.

For real estate investors, this matters enormously. Most small landlords, developers, and property managers fall well below $25 million in annual gross receipts. Therefore, they can access significant tax benefits that larger corporations cannot. The IRS Small Business Tax Center provides foundational guidance on these rules.

Which IRS Code Sections Use This Threshold?

Three major IRS code sections use the $25 million gross receipts test. Each provides a distinct benefit to qualifying businesses. Understanding all three helps you maximize your 2026 tax position.

• Section 448 — Allows qualifying businesses to use the cash method of accounting instead of the accrual method.
• Section 163(j) — Exempts qualifying businesses from the business interest expense limitation, allowing full deduction of mortgage interest.
• Section 471 — Allows qualifying businesses to use simplified inventory accounting methods or avoid certain inventory rules entirely.

Together, these three exemptions can dramatically reduce your tax burden and administrative complexity. Real estate investors who understand the right tax strategy can unlock all three benefits simultaneously, as long as they stay under the $25 million threshold. According to IRS Publication 538, the cash method of accounting is often far simpler and more favorable for cash-flow-focused investors.

Why Is $25 Million the Magic Number?

Congress established the $25 million threshold as part of the Tax Cuts and Jobs Act (TCJA) of 2017. Before that, the cash method was only available to businesses under $5 million in gross receipts. The TCJA raised it dramatically to $25 million, adjusted annually for inflation. For 2026, the threshold remains $25 million — verify the current figure at IRS.gov as it may be adjusted. This higher threshold opened the door for thousands of small- to mid-sized real estate businesses to benefit.

How Do You Qualify for the Small Business Exemption?

Qualifying for the small business exemption 25M gross receipts requires a careful calculation. You cannot simply look at your current-year revenue. Instead, the IRS requires a three-year average. Additionally, you must aggregate the gross receipts of all businesses under common ownership or control.

Step-by-Step: How to Calculate Your Gross Receipts

Follow these steps to check whether you qualify for the small business exemption for the 2026 tax year:

• Step 1: Gather total gross receipts for tax years 2023, 2024, and 2025 across all business entities you own or control.
• Step 2: Add the three years together and divide by three to get the average.
• Step 3: If the average is $25 million or less, you qualify for 2026.
• Step 4: Apply the aggregation rules — include all entities with more than 50% common ownership.
• Step 5: Confirm your accounting method election with your CPA and document it in your business records.

What Counts as Gross Receipts?

Gross receipts include all revenue from your real estate business. This covers rental income, property sales proceeds, fees, and other business income. However, it is not the same as net income. Even if your properties generate losses, gross receipts count the full rent collected — before expenses.

For example, if you own ten rental properties generating $200,000 per year in rents, your gross receipts are $200,000. That is far below the $25 million threshold. However, if you also own a commercial real estate brokerage generating $24 million in commissions, the combined total of $24.2 million approaches the limit. You must watch the aggregation rules carefully. Our entity structuring experts can help you stay within the threshold.

Revenue Type	Counts as Gross Receipts?
Rental income from residential properties	Yes
Proceeds from property sales	Yes (full sale price)
Property management fees	Yes
Interest income	Yes
Tax-exempt income	Yes (still included)
Capital contributions from partners	No

How Does This Exemption Help Real Estate Investors in 2026?

Real estate investors who qualify for the small business exemption 25M gross receipts gain three key advantages. Each advantage directly lowers taxable income or reduces accounting complexity. Together, they can represent tens of thousands of dollars in annual tax savings for a mid-sized real estate portfolio.

Advantage 1: Use the Cash Method of Accounting

Under IRS Section 448, C corporations and partnerships with C corporation partners must use the accrual method if they exceed the $25 million gross receipts threshold. However, if you stay under $25 million, you can use the cash method.

The cash method is far simpler for real estate investors. You report income when you receive it — not when you earn it. You deduct expenses when you pay them — not when you incur them. This aligns your tax reporting with your actual cash flow. For example, if a tenant pays January 2027 rent in December 2026, you can defer that income to 2027. That flexibility gives you powerful year-end tax planning options.

Furthermore, the cash method reduces bookkeeping costs. You don’t need complex accounts receivable or payable systems. This is a genuine simplification that saves both time and money every year. The tax filing team at Uncle Kam regularly helps investors switch to the cash method and realize immediate savings.

Advantage 2: Skip Complex Inventory Rules

Under Section 471, businesses that qualify under the small business exemption can use simplified inventory accounting. For most real estate investors, this means you don’t need to track costs and values of inventory items under complex IRS rules. This matters primarily for developers who build and sell homes — they hold real estate as inventory. Qualifying under the $25 million gross receipts test can dramatically simplify your year-end accounting.

How Does the Section 163(j) Exemption Work for Landlords?

Section 163(j) is the business interest expense limitation rule. It was introduced by the Tax Cuts and Jobs Act of 2017. Without the small business exemption, businesses can only deduct net business interest expense up to 30% of their adjusted taxable income (ATI). Any excess interest carries forward to future years. For highly leveraged real estate investors, this can be devastating.

However, if your average annual gross receipts are $25 million or less, Section 163(j) does not apply to you at all. You can deduct every dollar of mortgage interest you pay. This is a massive benefit for leveraged investors. Consider a landlord with $3 million in outstanding mortgages at a 7% average interest rate. That generates $210,000 in annual interest expense. Under Section 163(j), only a portion might be deductible. But with the small business exemption, the entire $210,000 is deductible.

The Section 163(j) Real Estate Election — An Alternative

Even real estate businesses that exceed $25 million in gross receipts have an option. They can make a special election under Section 163(j)(7) to treat their real estate activity as an electing real property trade or business. This election also allows full interest deductions. However, it comes with a significant trade-off: you must use a longer depreciation schedule (the Alternative Depreciation System, or ADS) for residential rental property and non-residential real property. Under ADS, residential rental property depreciates over 30 years instead of 27.5 years. That means smaller annual depreciation deductions.

In contrast, if you stay under the $25 million threshold and qualify for the small business exemption 25M gross receipts, you get full interest deductibility without any depreciation penalty. You keep your standard 27.5-year straight-line depreciation for residential rental property. This makes the gross receipts exemption significantly more valuable than the Section 163(j) election for most small landlords.

Scenario	Interest Deductibility	Depreciation Method
Under $25M (small business exemption)	100% deductible	MACRS (27.5-year residential)
Over $25M, no election made	Capped at 30% of ATI	MACRS (27.5-year residential)
Over $25M, Sec. 163(j)(7) election made	100% deductible	ADS (30-year residential)

What Did the OBBBA Change for Small Business Owners in 2026?

The One Big Beautiful Bill Act (OBBBA) was signed into law in 2025 and became fully effective for the 2026 tax year. It is the most significant tax legislation since the Tax Cuts and Jobs Act. For real estate investors and small business owners who rely on the small business exemption 25M gross receipts, the OBBBA brought several important changes.

OBBBA Change 1: The 20% QBI Deduction Is Permanent

The Qualified Business Income (QBI) deduction — Section 199A — was set to expire at the end of 2025 under the original TCJA. The OBBBA made it permanent. For 2026, eligible landlords and real estate business owners can still deduct up to 20% of their qualified business income. This is a massive win for rental property owners structured as pass-through entities. Combined with the small business exemption’s cash-method benefit, the QBI deduction can cut your effective tax rate significantly.

For example, an investor earning $200,000 in net rental income could deduct $40,000 through the QBI deduction. With the 2026 single standard deduction of $16,100, taxable income drops substantially. Talk to an Uncle Kam tax advisor to confirm your eligibility and maximize this deduction.

OBBBA Change 2: 1099 Reporting Threshold Raised to $2,000

Under the OBBBA, the federal Form 1099-NEC and 1099-MISC reporting threshold rose from $600 to $2,000, effective for all payments made on or after January 1, 2026. This matters for real estate investors who pay contractors for repairs, renovations, and property management. In prior years (the threshold was $600 in 2025), you had to issue 1099s for nearly every contractor. Now, only payments of $2,000 or more require a 1099. This reduces your paperwork burden significantly. Per Thomson Reuters Tax Analysis, states vary in whether they conform to this new federal threshold — so check your state rules as well.

OBBBA Change 3: 1099-K Threshold Restored

The OBBBA also restored the 1099-K reporting threshold to $20,000 and 200 transactions — reversing the controversial $600 no-minimum rule from the American Rescue Plan Act. If you collect rent through platforms like Airbnb or PayPal, you won’t receive a 1099-K unless your payments exceed $20,000 in 2026. This is a welcome relief for short-term rental investors who use digital payment platforms.

What Are the Most Common Mistakes Investors Make With This Exemption?

Many real estate investors lose the small business exemption 25M gross receipts benefits through avoidable errors. Understanding these pitfalls helps you protect your tax advantages. Our business owner clients regularly tell us these mistakes cost them far more than a CPA would have charged to prevent them.

Mistake 1: Forgetting the Aggregation Rules

Many investors own multiple LLCs for liability protection. However, the IRS requires you to aggregate gross receipts of all entities under common control when testing the $25 million threshold. Common control exists when the same person or group owns more than 50% of two or more entities. So if you own five LLCs, each generating $5 million in rent, your aggregated gross receipts are $25 million. You are right at the limit — and any additional income could push you over.

Mistake 2: Including a Large Property Sale in the Wrong Year

When you sell a property, the full sale proceeds count as gross receipts in that year — even though most of it may be return of capital. A single $10 million property sale can spike your gross receipts. If that pushes your three-year average above $25 million, you lose the exemption. However, this may only last for the years affected by the rolling average. Plan large sales carefully with a tax strategist to minimize disruption to your exemption status.

Mistake 3: Never Formally Electing the Cash Method

Qualifying for the small business exemption does not automatically change your accounting method. If you have been using the accrual method, you must formally elect to switch to the cash method. This typically requires filing IRS Form 3115 (Application for Change in Accounting Method). Missing this step means you don’t get the benefit — even if you would otherwise qualify. Work with a tax professional to make this election properly.

Mistake 4: Ignoring State Tax Conformity

Not all states conform to the federal $25 million gross receipts threshold. Some states have their own rules for when businesses must use the accrual method. California, for example, has decoupled from certain federal provisions over the years. Similarly, states vary on whether they adopt the OBBBA’s $2,000 threshold for 1099 reporting. Always check your state’s rules alongside the federal rules. The Uncle Kam compliance team monitors state-level changes so you don’t have to.

 

 

Uncle Kam in Action: How One Investor Saved $47,000 Using the Small Business Exemption

Client Snapshot: Marcus T. is a full-time real estate investor in his early 40s. He owns 18 residential rental properties spread across three LLCs. His total portfolio generates about $620,000 per year in rental income. He also flips two to three properties per year, adding another $300,000 in gross receipts. Before working with Uncle Kam, Marcus had a different CPA who filed all three LLCs on the accrual basis and never claimed the Section 163(j) exemption.

The Challenge: Marcus was paying over $190,000 in federal and state taxes annually. His CPA had never analyzed his gross receipts across all three LLCs. Each LLC was under $5 million individually, but combined they totaled $920,000 — well under $25 million. His prior CPA was also not deducting his full mortgage interest. Because Marcus’s properties were highly leveraged with $4.2 million in outstanding mortgages, his annual interest expense exceeded $294,000. However, his prior return limited the interest deduction under Section 163(j) unnecessarily — even though Marcus clearly qualified for the small business exemption.

The Uncle Kam Solution: The Uncle Kam team reviewed Marcus’s full entity structure. They confirmed that his aggregated gross receipts across all three LLCs were approximately $920,000 — far below the $25 million threshold. The team then filed IRS Form 3115 to formally switch Marcus to the cash method. They also removed the Section 163(j) limitation and deducted his full $294,000 in mortgage interest. Additionally, they claimed the 20% QBI deduction on his net rental income, further reducing his taxable income. The team also restructured his entity setup to clearly separate flipping activity (ordinary income) from rental activity (passive income), improving his overall tax profile.

The Results in 2026:

• Tax Savings: $47,200 in the first year alone
• Uncle Kam Fee: $7,500
• First-Year ROI: 529%
• Estimated 5-Year Cumulative Savings: Over $230,000

“I had no idea I was leaving almost $50,000 on the table every year,” Marcus said. “The team at Uncle Kam found it in weeks. It was the best investment I’ve made in my real estate business.” Read more stories like Marcus’s on our client results page.

Frequently Asked Questions

Is the $25 million gross receipts threshold adjusted for inflation in 2026?

Yes. The Tax Cuts and Jobs Act established the $25 million gross receipts threshold and tied it to annual inflation adjustments. For 2026, the threshold remains at $25 million. However, you should verify the exact figure each year at IRS.gov since inflation adjustments are published annually in IRS Revenue Procedures. If inflation drives the threshold higher in a given year, more businesses will qualify for the exemption automatically.

Can a real estate syndication or partnership qualify for the small business exemption?

Yes, partnerships can qualify — but with limitations. Partnerships that include C corporations as partners must use the accrual method unless the entire partnership qualifies under the $25 million gross receipts test. If all partners are individuals, trusts, or S corporations, the partnership can use the cash method if it meets the threshold. For real estate syndicators, this is an important planning point. Structure your partnerships carefully to preserve access to the exemption. Our entity structuring experts specialize in exactly this type of planning.

What happens if I exceed the $25 million threshold in one year?

If your three-year average gross receipts exceed $25 million, you lose the small business exemption for that tax year. You must switch to the accrual method and comply with Section 163(j) interest limitations. However, if your receipts fall back below the threshold in future years, you can re-qualify. You will need to file Form 3115 again to change your accounting method. This can be disruptive, which is why proactive planning — such as timing large property sales and using installment sales or 1031 exchanges — is so important. The Uncle Kam advisory team helps investors avoid triggering this threshold unexpectedly.

Does rental income from short-term rentals (STRs) count toward gross receipts?

Yes. All revenue from your real estate business counts as gross receipts — including Airbnb, VRBO, and other short-term rental platforms. It does not matter whether the rental period is one day or one year. The total amount you collect from tenants or guests is included. However, the IRS does not count security deposits you intend to return, capital contributions from partners, or sales proceeds from assets that are not inventory. If you are unsure what to include, consult a tax professional and review IRS Publication 538 for guidance on gross receipts calculations.

Does REPS (Real Estate Professional Status) affect eligibility for the small business exemption 25M gross receipts?

No — Real Estate Professional Status (REPS) and the small business exemption 25M gross receipts are two separate IRS rules. REPS determines whether your rental losses are passive or non-passive. To qualify for REPS, you must spend more than 750 hours per year and more than 50% of your total working time in real estate activities. The gross receipts exemption, on the other hand, determines your accounting method and interest deductibility. You can qualify for one, both, or neither. However, many high-earning real estate investors benefit from pursuing both — REPS unlocks passive loss deductions while the gross receipts exemption maximizes interest deductions and simplifies accounting. Check our tax strategy blog for more on combining REPS with the small business exemption.

How does the OBBBA specifically affect the small business exemption in 2026?

The One Big Beautiful Bill Act (OBBBA) did not eliminate or reduce the small business exemption 25M gross receipts threshold. In fact, it reinforced the tax environment that makes this exemption so valuable. The OBBBA made the 20% QBI deduction permanent, which pairs powerfully with the cash method election. It also raised the 1099-NEC/MISC threshold to $2,000 for 2026, reducing administrative burden. Additionally, it restored the 1099-K threshold to $20,000/200 transactions. These changes collectively make 2026 an excellent year for qualifying small real estate businesses to maximize every available tax advantage.
