The gross receipts threshold that separates a small business taxpayer from everyone else rises to $33,000,000 for tax years beginning in 2027. The figure sits in Section 3.32 of Rev. Proc. 2026-35, which the IRS released on November 5, 2026 as part of the tax year 2027 inflation adjustments. One number, and it controls four separate tax rules that a growing equipment distributor feels in its working capital.

This is not a filing detail that lives with the accountant. The gross receipts threshold test looks at average annual gross receipts for the three prior tax years, so the year a distributor crosses the line is decided by revenue already booked. A dealer that grew hard in 2025 and 2026 may already have locked in a 2027 result it has not priced for.
What the 2027 gross receipts threshold changes
Rev. Proc. 2026-35 carries the figure under the heading “Limitation on Use of Cash Method of Accounting,” which is the section 448 rule. But the same section 448(c) test is borrowed by other provisions, so one measurement answers several questions at once. The IRS set the comparable amount at $32 million for 2026, and the Instructions for Form 8990 state that “For tax years beginning in 2025, a taxpayer meets the gross receipts test if the taxpayer has” “average annual gross receipts of $31 million or less for the 3 prior tax years.”
A $1 million step each year sounds generous until it is set against equipment price inflation and a larger order book. Revenue growth that feels healthy on a sales report can move a distributor across an accounting line that was never part of the plan.
Four rules that ride on the gross receipts threshold
Treasury’s final regulations on this topic, TD 9942, are titled for the sections involved: 263A, 448, 460 and 471. The regulations implement exceptions that apply to taxpayers “other than a tax shelter under section 448(a)(3), meeting the gross receipts test,” and they describe the relief from the section 471(a) requirement to take inventories as available “if their inventory is treated as non-incidental materials and supplies.”
| Provision | What the exception generally allows while the test is met | What a distributor feels when it is not met |
|---|---|---|
| Section 448, cash method | Use of the cash method of accounting, within the limits of the statute | For a C corporation, a partnership with a C corporation partner, or a tax shelter, a move to an accrual method and a change in when revenue and expense land; section 448 does not reach an S corporation, a partnership without a C corporation partner, or a sole proprietorship |
| Section 263A, uniform capitalization | Exemption from capitalizing additional indirect costs into inventory | Freight-in, handling, storage and related indirect costs pulled into inventory cost |
| Section 471(c), inventories | Inventory treated as non-incidental materials and supplies rather than under section 471(a) | A return to the general inventory rules, with the record keeping that follows |
| Section 163(j), business interest | Exemption from the limitation on deducting business interest expense | Interest deductible only up to the statutory sum, described below |
The inventory items reach deep into a distributor’s cost structure, which is full of exactly the indirect costs that uniform capitalization reaches. Inbound freight on a container of cardio, warehouse rent, and the labor that receives and stages units stop being current-period costs and start sitting in inventory until the unit sells. That is a timing change, not a permanent one, but the first year of it lands as a tax bill on stock still on the floor. It is also a reason to watch the monthly cost of stock aging past 180 days with more care, not less.
The interest limitation, and a trap specific to equipment
The IRS describes the section 163(j) limitation plainly: the deduction cannot exceed the sum of business interest income, “30% of the taxpayer’s adjusted taxable income (ATI) for the taxable year,” and floor plan financing interest expense. The agency’s own questions and answers on the limitation state that it applies to all taxpayers with business interest expense “other than certain small businesses that meet the gross receipts test in section 448(c).”
A dealer reading that list will reasonably stop at the third item. Inventory finance is the lifeblood of equipment distribution, and a full deduction for it would soften the whole problem. The definition does not cooperate. The Instructions for Form 8990, revised December 2025, define the term this way: “Floor plan financing interest expense is interest on debt used to finance the acquisition of motor vehicles” and certain trailers and campers “that is held for sale or lease” “where the debt is secured by the acquired inventory.”
Motor vehicles for this purpose are a defined and narrow set. IRS Fact Sheet FS-2026-14, current as of August 19, 2026, states that “For purposes of floor plan financing, a motor vehicle is defined as any one of the following:” “A self-propelled vehicle designed for transporting persons or property on a public street,” “A boat, and” “Farm machinery or equipment,” and that for tax years beginning after December 31, 2024 the term also includes certain trailers and campers designed to provide temporary living quarters.
Treadmills and racks are not in that set, so interest on a fitness-equipment inventory line generally falls outside the floor plan carve-out and lands inside the ordinary limitation once a distributor stops meeting the gross receipts test. Anyone running a floor plan inventory and cash-flow review should ask the company’s tax adviser how that interest is being treated before assuming the carve-out applies.
Two further notes from the same instructions. “A small business taxpayer is not subject to the section 163(j) limitation and is generally not required to file Form 8990,” which is why crossing the line also adds a form. And “A taxpayer that is a tax shelter as defined in section 448(d)(3) is not permitted to use the small business exemptions” “contained in section 163(j)(3),” so entity structure matters independently of size.
A worked example, with the assumptions stated
The receipts below are assumptions chosen to show the arithmetic, not industry figures. Assume a distributor with no predecessor entity and no aggregation adjustment under section 448(c)(2), and assume gross receipts of $28.0 million in 2024, $32.0 million in 2025, $38.0 million in 2026 and a budgeted $40.0 million in 2027.
| Tax year tested | Three prior years used | Sum | Average annual gross receipts | Result |
|---|---|---|---|---|
| 2027 | 2024, 2025, 2026 | $98.0 million | $32.7 million | At or below the published $33.0 million figure, so the test is met |
| 2028 | 2025, 2026, 2027 | $110.0 million | $36.7 million | Above the 2027 figure used here as a placeholder, because the 2028 amount is not published yet |
The averages are 98.0 divided by 3, which is 32.7 million rounded, and 110.0 divided by 3, which is 36.7 million rounded. The lesson is in the second row: a distributor in this position has roughly a year of warning and should spend it on an accounting method plan.
Section 179 in 2027, and where it stops helping
The same revenue procedure resets the expensing figures. For tax years beginning in 2027, Section 3.26 sets the section 179(b)(1) dollar limitation at “$2,640,000,” applies the section 179(b)(2) reduction to the extent section 179 property placed in service during the year exceeds “$4,230,000,” and caps the cost of a sport utility vehicle at “$33,100.” The IRS stated the headline change in its November 5, 2026 release: “For tax year 2027 taxpayers can expense up to $2,640,000 of section 179 property, up from $2,560,000 for tax year 2026.”
The reduction is arithmetic worth running once. On a stated assumption of $4,500,000 of section 179 property placed in service during 2027, the excess over $4,230,000 is $270,000, and the $2,640,000 limitation is reduced by that amount to $2,370,000.
Two statutory limits sit behind the headline number. The United States Code text of section 179 provides that the deduction “shall not exceed the aggregate amount of taxable income of the taxpayer for such taxable year” “which is derived from the active conduct by the taxpayer of any trade or business during such taxable year,” with a carryover of the disallowed amount, and it requires the election to “specify the items of section 179 property to which the election applies” and to “be made on the taxpayer’s return.” Property must also be “acquired by purchase for use in the active conduct of a trade or business.”
Separately, Treasury and the IRS issued guidance on January 14, 2026 on what the agency describes as “the permanent 100% additional first year depreciation deduction,” applicable to “eligible depreciable property acquired after Jan. 19, 2025.” Where that deduction is available, a section 179 election is often less decisive than it once was, and the placed-in-service date does the real work. That is the same date discussed in the ready-for-use test that starts depreciation on a year-end installation.
Six checks before the 2027 books open
- Compute the three-year average now. Use 2024, 2025 and 2026 gross receipts and compare the average to the published gross receipts threshold of $33,000,000 for tax years beginning in 2027.
- Ask about aggregation. TD 9942 notes the section 448(c)(2) aggregation rules can apply, so related entities, a predecessor, or commonly controlled companies may be measured together. This is a question for the company’s tax adviser.
- Price the inventory consequence, not just the tax rate. Identify the indirect costs that uniform capitalization would pull into inventory: inbound freight, warehouse occupancy, receiving labor, handling and storage.
- Separate interest by facility. Split inventory finance, real estate debt and equipment term debt in the general ledger so the interest limitation can be computed without a reconstruction project.
- Confirm the floor plan question in writing. Ask the tax adviser to state in writing whether any of the company’s interest meets the statutory definition, which is written around vehicle inventory rather than fitness equipment.
- Decide the capital calendar on the facts. Place the section 179 limitation, the $4,230,000 reduction point and the 100% additional first-year deduction side by side before committing December or January delivery dates.
Warning signs and common mistakes
- Treating the current year’s revenue as the test. The measurement is the average of the three prior years, so the decision year is already largely determined.
- Assuming inventory finance is always fully deductible because a vehicle dealer told you so. The definition is written for a different industry.
- Reading the threshold as a cliff for the whole company when the aggregation rules may bring affiliates into the measurement.
- Letting a strong fourth quarter decide the question by itself. Growth that pushes receipts up is the same growth that funds the stock, and it can shift both the accounting method and the carrying cost at once.
- Running the analysis without the receivable picture. A method change interacts with collection timing, which is why customer credit limits set before equipment ships belong in the same review.
Records and metrics to pull
Pull gross receipts by tax year for the last four years, a list of related and commonly controlled entities, the inventory subledger with inbound freight coded separately, interest expense by facility, and the fixed asset additions schedule with placed-in-service dates. Those five items answer many of the questions a tax adviser is likely to ask, and assembling them in November is far cheaper than assembling them under a filing deadline.
Does the gross receipts threshold apply to a single-location dealer?
It can. The test is written around average annual gross receipts rather than headcount or location count, and TD 9942 notes that the section 448(c)(2) aggregation rules can apply. A single-location dealer with high equipment revenue and affiliated entities should ask the question rather than assume the answer.
What happens to the exemption in a year receipts fall back?
The test is applied year by year against the three prior tax years, so a decline can change the result in a later year. The practical effect on accounting methods, including whether a method change is needed or permitted, is a question for the company’s tax adviser, because a change in method is a separate process from meeting the test.
The action this month is small. Compute the three-year average, write it on one line next to the 2027 gross receipts threshold, and send that line to the company’s tax adviser with the question of what changes if the result goes the wrong way. Thresholds are adjusted annually and rules can be amended, so confirm current figures and their application to your entity with a qualified adviser before acting on them.
