SB2100 (Modernizing Agricultural and Manufacturing Bonds Act) revises the Internal Revenue Code’s rules for qualified small-issue manufacturing bonds and adjusts exceptions to the private activity bond rules that apply to first-time farmers. The bill adds intangible property production and related ancillary facilities to the definition of ‘‘manufacturing facility,’’ raises multiple dollar caps on small-issue manufacturing bonds, and creates automatic inflation adjustments for those caps.
Separately, the bill boosts the per-project and per-taxpayer dollar limits that first-time farmers can access under the private activity bond exceptions (raising a $450,000 cap to $1,000,000 and aligning related small-issue limits), repeals a lower separate cap on used equipment, and changes how ‘‘substantial farmland’’ is measured. Those changes alter eligibility, administrative calculations for issuers, and the fiscal exposure of federal tax-exempt financing.
At a Glance
What It Does
The bill broadens the statutory definition of a manufacturing facility to cover certain intangible property production and functionally related facilities, increases small-issue manufacturing bond caps (from $10M to $30M and aggregate taxpayer caps proportionally), and attaches cost-of-living indexing to those limits. It also raises first-time farmer bond limits to $1M, removes a separate lower cap for used equipment, and switches farmland measurement from median to average farm size.
Who It Affects
State and local issuers and conduit borrowers that use qualified small-issue manufacturing bonds, manufacturers that produce intangible property (e.g., certain IP or software-related production), first-time farmers seeking tax-exempt financing, and municipal finance counsel and compliance officers tasked with allocation and reporting.
Why It Matters
The changes expand which manufacturing and agricultural projects can use tax-exempt financing, increase per-issue and per-taxpayer capacity, and lock those increases to inflation—potentially shifting economic development incentives, issuer allocation practices, and federal revenue costs over time.

What This Bill Actually Does
SB2100 begins by updating the statutory definition of a ‘‘manufacturing facility’’ used for qualified small-issue manufacturing bonds. In addition to traditional production of tangible personal property, the bill explicitly includes production or creation of certain intangible property (cross-referencing section 197(d)(1)(C)(iii)) and permits facilities that are functionally related and subordinate to a manufacturing site to qualify when located on the same site.
The bill limits ancillary facilities so that no more than 25% of net bond proceeds fund those ancillary uses and applies an office-space limitation modeled on existing section 142(b)(2).
The bill substantially raises the monetary ceilings that govern small-issue manufacturing bonds. It increases the per-issue cap referenced in section 144(a)(4) from $10,000,000 to $30,000,000, raises the additional-capital-expenditure parameter to the same new threshold for post-enactment bonds, and triples the aggregate per-taxpayer cap in section 144(a)(10)(A) from $40,000,000 to $120,000,000.
To prevent those amounts from eroding over time, SB2100 applies an annual cost-of-living adjustment to the new dollar caps for calendar years after 2025 and specifies rounding to the nearest $100,000.To protect the status of existing financings, the bill bars the retroactive application of the new intangible- and subordinate-facility inclusions to bonds issued on or before enactment and to refundings of such pre-enactment bonds (subject to a narrow exception for certain prior office-space rules). The increases in the numeric caps, however, apply to obligations issued after enactment.On the agricultural side, SB2100 raises the first-time farmer exception ceiling in section 147(c)(2)(A) from $450,000 to $1,000,000 and brings the qualified small-issue bond limit in section 144(a)(11)(A) into parity by increasing it from $250,000 to $1,000,000.
The bill removes a distinct lower dollar limit that previously applied to used farm equipment, meaning acquisitions of used equipment will no longer be separately capped. The statutory test for ‘‘substantial farmland’’ shifts from comparing to the median farm size in a county to the average farm size, and the first-time farmer amounts become subject to an inflation adjustment beginning in the years after 2026, with changes to rounding rules to $10,000 increments.
The Five Things You Need to Know
The bill adds production of certain intangibles (per section 197(d)(1)(C)(iii)) and on-site functionally related subordinate facilities to the definition of a qualifying ‘‘manufacturing facility.’, It raises the per-issue small-issue manufacturing bond cap from $10,000,000 to $30,000,000 and the aggregate per-taxpayer cap from $40,000,000 to $120,000,000.
SB2100 creates annual inflation adjustments for the new $30M/$120M thresholds for calendar years after 2025, with rounding to the nearest $100,000.
For first-time farmers, the per-project dollar limit increases from $450,000 to $1,000,000, the related small-issue cap moves from $250,000 to $1,000,000, and the separate lower cap on used equipment is repealed.
The bill changes the farmland-size test used to define ‘‘substantial farmland’’ from county median to county average farm size and phases in inflation indexing of the farmer amounts after 2026, with rounding rules adjusted to $10,000.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Redefines 'manufacturing facility' to include certain intangibles and subordinate facilities
This amendment to section 144(a)(12)(C) expands qualifying manufacturing facilities to include sites that create or produce intangible property identified in section 197(d)(1)(C)(iii) and facilities that are functionally related and subordinate when on the same site. Practically, that brings some IP- or R&D-adjacent production activities into eligibility for tax-exempt small-issue manufacturing bonds, subject to an office-space limitation and a cap that no more than 25% of net proceeds fund ancillary facilities.
Non-retroactivity rule for existing bonds and refundings
The bill prevents the new intangible- and subordinate-facility inclusions from applying to bonds issued on or before enactment or to refundings of such bonds (with a limited exception tied to a prior office-space rule). This preserves the status of outstanding financings and restricts issuers from immediately recharacterizing older obligations to take advantage of the broadened definition.
Raises numeric caps and adds inflation indexing
Section 144(a)(4) is updated to raise the per-issue cap to $30,000,000 and section 144(a)(10)(A) raises the aggregate taxpayer cap to $120,000,000. The bill adds a new paragraph to authorize annual cost-of-living adjustments for those amounts beginning after 2025, specifies the statutory indexing method (a substitute in section 1(f)(3)), and requires rounding to $100,000 increments. Issuers and borrowers must track adjusted ceilings each year to confirm eligibility.
Effective date for manufacturing bond changes
All amendments in Section 2 apply to obligations issued after the date of enactment. That timing means issuers cannot apply the expanded facility definition or higher caps to obligations issued before enactment, although the law preserves refunding protections discussed earlier.
Increases first-time farmer dollar limits and removes used-equipment cap
Amendments to section 147(c)(2) raise the dollar limit for first-time farmer qualified financing to $1,000,000 and align the small-issue subgroup limit in section 144(a)(11)(A) at $1,000,000. The bill repeals a separate lower cap that had applied specifically to used farm equipment. Practically, these shifts expand the financing envelope available to new farmers and simplify the statutory structure governing equipment acquisitions.
Inflation adjustment and farmland measurement change
SB2100 modifies the inflation-adjustment trigger language so the first-time farmer dollar amounts are subject to indexing after 2026 and increases the rounding increment from $100 to $10,000. Independently, the ‘‘substantial farmland’’ metric now uses average farm size rather than median, which alters eligibility calculations in counties where distribution of farm sizes is uneven and may allow larger operations to qualify under the exception.
Effective date for first-time farmer changes
The first-time farmer provisions apply to bonds issued after December 31, 2025. This creates a discrete window before the higher limits and measurement changes take legal effect, giving state issuers and agricultural borrowers time to adapt allocation procedures.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- First-time farmers seeking tax-exempt financing — the per-project and small-issue caps increase to $1,000,000 and indexing eliminates erosion over time, broadening access to low-cost capital for land and equipment purchases.
- Manufacturing and production entities that create qualifying intangible property (e.g., certain software, biotech processes, or other IP-intensive production) — the broadened facility definition allows more IP-related production to tap small-issue bonds.
- State and local economic development issuers and conduit lenders — higher caps increase the pool of projects they can finance tax-exemptly and give them more flexibility to support larger manufacturing or agricultural projects.
- Rural communities and associated supply chains — more capital availability for farm startups and IP-adjacent manufacturing can spur local investment, jobs, and secondary economic activity.
- Bond counsel and municipal finance professionals — the bill generates new advisory and compliance work around eligibility, allocation, and applying the new inflation-indexed ceilings.
Who Bears the Cost
- Federal Treasury (indirectly) — larger and indexed tax-exempt financing capacity increases foregone federal revenue from tax-exempt interest over time.
- State and local issuers — administrative burdens rise as issuers must apply new eligibility rules, monitor inflation-adjusted ceilings annually, and document that ancillary facilities do not exceed the 25% proceeds limit.
- IRS/Tax administrators — the agency must issue guidance interpreting the inclusion of intangible production, the boundaries of 'functionally related' facilities, and transitions for refundings, increasing enforcement and guidance workload.
- Competing borrowers (other municipal projects) — expanding caps and eligibility concentrates tax-exempt allocation toward manufacturing and first-time farmer projects, potentially reducing availability for other exempt uses in jurisdictions with scarce volume cap or issuer capacity.
- Conventional lenders and leasing companies (in some cases) — expanded tax-exempt options for borrowers may crowd out private financing opportunities for equipment or land.
Key Issues
The Core Tension
The central dilemma SB2100 presents is a policy trade-off between expanding low-cost tax-exempt capital to stimulate manufacturing and farm startups and protecting the integrity and fiscal cost of the tax-exempt bond system: broader eligibility and higher indexed caps can accelerate investment in targeted sectors but also increase federal revenue loss and risk subsidizing projects that might otherwise attract private financing.
The bill creates several implementation questions that will fall to Treasury and state issuers. First, including intangible property production imports a longstanding substantive test (section 197 cross-reference) into the municipal bond context; regulators will need to clarify what kinds of R&D, software, or IP creation qualify as ‘‘production’’ for tax-exempt purposes and where research or licensing activities remain ineligible.
Second, the 25% cap on net proceeds for ancillary facilities and the office-space limitation will require issuers to establish new documentation and allocation practices to avoid disallowed private business use — a nontrivial compliance task for complex industrial campuses.
On the agricultural side, switching from median to average farm-size calculations materially changes the eligibility landscape in many counties and could allow larger farms to meet the ‘‘substantial farmland’’ test. Repealing the separate limit on used equipment simplifies the statute but may invite strategic timing of purchases to fit within the new per-project cap.
Finally, the inflation indexing language differs between manufacturing and farmer provisions (different start years and rounding conventions), adding bookkeeping complexity for state allocators and counsel who must track multiple adjustment rules and apply them correctly to new issuances.
