Industrial revenue bonds: the complete guide
How private companies borrow at tax-exempt rates through a public issuer — who qualifies, the federal rules, volume cap, the timeline, what it costs, how the bonds are sold, and who buys them.
Key takeaways ¶
- Tax-exempt borrowing for private companies. A state or local issuer sells the bonds and lends the money on; because buyers pay no federal tax on the interest, the rate is typically well below a comparable taxable loan.
- Eligibility is set by the tax code. Manufacturing projects can borrow up to $10 million under the capital expenditure election, with capital spending held within $20 million over six years (IRC §144(a)); solid waste, water, qualified housing and certain other facilities qualify without that limit (§142).
- Most deals need volume cap. Each state receives an annual allocation of private activity bond authority — $49.8B across all states this year — and decides how to share it.
- Fixed costs decide the size threshold. One-time costs run about 3.2% of par on an $8 million deal; fixed costs weigh heavily on small issues, and most fund buyers look for unrated placements of several million dollars or more, so the smallest deals usually go to a bank as a direct purchase or stay as conventional loans.
- The buyer base is deep. SEC-registered funds hold $107.3B of conduit revenue bonds, +8.3% over the past year, and FDIC-insured banks hold $284.9B of municipal securities of all types.
- Plan on three to six months. Inducement, a public (TEFRA) hearing, volume cap and documentation run in parallel; cap rounds can add more.
1. What an industrial revenue bond is ¶
An industrial revenue bond (IRB), also called an industrial development bond, is a tax-exempt bond issued by a state or local government entity — usually a development authority, finance authority or county industrial development board — on behalf of a private company. The issuer lends the bond proceeds to the company under a loan or lease agreement. The company makes the payments; the bondholders rely on the company’s credit (and any collateral or bank support), not on the issuer’s taxing power.
Because the bonds qualify under the Internal Revenue Code, interest paid to most investors is exempt from federal income tax, and often from the issuing state’s tax for in-state holders. Investors therefore accept a lower yield than on taxable debt of the same credit, and that saving passes to the borrower.
The issuer lends its tax-exempt status, not its credit. The company’s business repays the bonds.
2. Who qualifies ¶
Federal law limits tax-exempt private activity bonds to specific purposes. For most industrial borrowers the route is the qualified small issue for manufacturing facilities: up to $1 million per issue, or up to $10 million when the issuer makes the capital expenditure election — provided capital spending at the facility and related sites over the six-year test period (three years before and three after the issue) stays within $20 million (IRC §144(a)(1), (a)(4)). In practice almost every deal uses the election. A pending bill, the Modernizing Agricultural and Manufacturing Bonds Act (S. 2100; House companion H.R. 9100), would raise the $10 million limit to $30 million and the $40 million per-borrower limit to $120 million, indexed for inflation; it is not law (see the legislative watch). Other projects qualify as exempt facilities without that size limit.
| Category | Code section | Size limit | Volume cap | Typical borrowers |
|---|---|---|---|---|
| Qualified small issue (manufacturing) | §144(a) | $1M; $10M under the capital expenditure election, with six-year capital spending ≤ $20M | Yes | Manufacturers and processors |
| Solid waste disposal | §142(a)(6) | None | Yes (unless government-owned) | Recyclers, landfill and waste-to-energy operators |
| Water and sewage facilities | §142(a)(4)–(5) | None | Yes for private users | Private water and wastewater companies |
| Qualified residential rental | §142(d) | None; set-aside tests | Yes | Affordable housing developers |
| Local electric, gas and district heating/cooling | §142(a)(8)–(9) | Service-area limits | Yes | Local utilities |
| Airports, docks and wharves, mass commuting | §142(a)(1)–(3) | None | No if governmentally owned | Port and airport tenants |
| Spaceports | §142(a)(16) | None | No if governmentally owned | Launch and recovery facility tenants (added 2025) |
| Highway and surface freight transfer facilities | §142(m) | National $30B allocation | No — allocated by U.S. DOT | Transportation public-private partnerships |
| Qualified broadband and carbon dioxide capture | §142(a)(17)–(18) | Program rules | Yes (partial exceptions) | Rural broadband and carbon capture projects (added 2021) |
| First-time farmer | §147(c)(2) | Lifetime limit per farmer, indexed | Yes | New farmers buying land or equipment |
| Qualified 501(c)(3) | §145 | None | No | Nonprofit hospitals, schools, museums |
Projects that are not eligible include retail, offices, hotels and restaurants, and warehouses that are not part of a manufacturing operation. Those borrowers use bank loans, SBA programmes or taxable placements instead.
3. The federal requirements ¶
Beyond eligibility, every issue must meet a set of tests that bond counsel confirms in the tax certificate at closing. Breaching them after closing can make interest taxable, so they shape how the project is structured and run.
| Requirement | What it means | Authority |
|---|---|---|
| Use of proceeds | At least 95% of net proceeds finance the qualifying facility. Issuance costs paid from proceeds, working capital and any other non-qualifying use together must fit within the remaining 5%. For small issues, no more than 25% for directly related and ancillary uses. | §144(a)(12); §142 |
| Land | No more than 25% of net proceeds may buy land (special rules for farm land). | §147(c) |
| Existing property | Buying an existing building requires rehabilitation spending of at least 15% of the bond-financed acquisition cost within two years. Used equipment can be financed only as part of a building rehabilitation or with rehabilitation equal to 100% of its cost. | §147(d) |
| Maturity | Average maturity no longer than 120% of the average reasonably expected economic life of the financed assets. | §147(b) |
| Costs of issuance | No more than 2% of proceeds may pay costs of issuance; the rest is paid by the borrower. | §147(g) |
| Public approval | A public hearing after at least 7 days’ notice (website notice permitted) and approval by an elected official — the TEFRA hearing. If the issuer is outside the project’s jurisdiction, such as a national conduit, the host jurisdiction’s elected official must also approve. Approval lapses if bonds are not issued within one year. | §147(f); Treas. Reg. §1.147(f)-1 |
| Prohibited facilities | No skyboxes, airplanes, health clubs, gambling or liquor stores, among others. | §147(e) |
| Beneficiary limit | No owner or principal user of the facility during the test period (with related persons) may be allocated more than $40 million of this issue plus all its outstanding tax-exempt facility-related bonds — small-issue and exempt-facility — nationwide. | §144(a)(10) |
| Arbitrage | Investment earnings above the bond yield are rebated to the U.S. Treasury; spending exceptions apply. | §148; Treas. Reg. §1.148 |
| Reimbursement | Costs paid up to 60 days before the issuer’s declaration of official intent (inducement), and any time after it, may be reimbursed; the allocation must be made within 18 months of the later of payment or placed-in-service, and within three years of payment. Preliminary costs up to 20% of the issue need no prior declaration. | Treas. Reg. §1.150-2 |
| Information return | Form 8038 is filed with the IRS after closing. | §149(e) |
4. Volume cap ¶
Most private activity bonds must receive an allocation of the state’s annual volume cap (IRC §146). The IRS sets each state’s amount from a per-resident figure, with a minimum for small states; each state then allocates it by statute or by an allocating agency — through application rounds, set-asides for categories such as housing or manufacturing, or first-come first-served. Unused cap can be carried forward for up to three years for a stated purpose.
| State | Volume cap | Population | Basis |
|---|---|---|---|
| California | $5.3B | 39.36M | per capita |
| Texas | $4.3B | 31.71M | per capita |
| Florida | $3.2B | 23.46M | per capita |
| New York | $2.7B | 20.00M | per capita |
| Pennsylvania | $1.8B | 13.06M | per capita |
| Illinois | $1.7B | 12.72M | per capita |
| Ohio | $1.6B | 11.90M | per capita |
| Georgia | $1.5B | 11.30M | per capita |
| North Carolina | $1.5B | 11.20M | per capita |
| Michigan | $1.4B | 10.13M | per capita |
| New Jersey | $1.3B | 9.55M | per capita |
| Virginia | $1.2B | 8.88M | per capita |
Allocation is often the critical path. Borrowers should learn their state’s calendar early and have an inducement resolution in place before applying. See the volume cap tracker and the state guides.
5. From idea to closing ¶
- Feasibility and financials. Confirm the project type and size, assemble three years of financial statements and projections, and estimate costs.
- Choose an issuer and obtain an inducement. A local development authority adopts an inducement resolution — the official declaration of intent that allows reimbursement of later costs.
- Apply for volume cap. Submit the state application with the inducement, project description and jobs data.
- Hold the TEFRA hearing. Publish notice at least seven days ahead, hold the hearing and obtain the elected official’s approval.
- Document and diligence. Bond counsel drafts the indenture, loan agreement and tax certificate; buyers review financials, collateral and the site.
- Market and price. The placement agent or underwriter takes indications from buyers and sets the rate and terms.
- Close and fund. Documents are signed, proceeds go to the trustee and are drawn as the project is built.
6. The borrower’s term sheet ¶
Before documents are drafted, the purchaser or placement agent and the borrower agree a term sheet. It fixes the economics and the protections; the indenture and loan agreement then follow it. Read it as the deal: changing a term later costs time and legal fees.
| Heading | Illustrative entry | What to look for |
|---|---|---|
| Issuer | [Development authority] | The conduit whose name is on the bonds. Check its fee, its approval calendar and whether it needs its own counsel. |
| Borrower and guarantors | [Company]; [parent or owners] | Who signs the loan agreement and who guarantees it. Personal or parent guarantees are common for younger companies. |
| Par amount | Up to $[ ] | Must fit the small-issue limits and the 2% cost-of-issuance cap; the excess cost comes from the company. |
| Purpose | Acquire, construct and equip [facility] at [address] | Must match the inducement, the TEFRA notice and the volume cap allocation. |
| Tax status | Tax-exempt; interest an AMT preference item | Private activity bond interest is an individual AMT preference (IRC §57(a)(5)); AMT-free funds cannot buy. |
| Security | Loan payments; first mortgage on [site]; security interest in equipment | What bondholders can take if payments stop. Equipment collateral loses value faster than real estate. |
| Credit enhancement | [None] / [direct-pay letter of credit from Bank] | Replaces the company’s credit with a bank’s; see the next section. |
| Rate and mode | [Fixed] [%] / [weekly variable] | Fixed to maturity, fixed to a bank tender date, or variable with a liquidity facility. |
| Maturity and amortisation | Final maturity [year]; sinking fund from [year] | Average maturity may not exceed 120% of the assets’ economic life (IRC §147(b)). |
| Denominations | $100,000 minimum | Large denominations keep a limited offering within the Rule 15c2-12 exemption. |
| Optional redemption | Callable at par after [ ] years | Call protection is what buyers trade for a lower rate; a shorter non-call period costs yield. |
| Extraordinary redemption | Casualty, condemnation, determination of taxability | A taxability event usually forces redemption, sometimes at a premium or with a gross-up. |
| Covenants | Debt service coverage of [ ]x; limits on additional debt; annual audit | Breaching a covenant is a default even if payments are current. Negotiate tests the business can meet in a bad year. |
| Reserve fund | [None] / [ ] of maximum annual debt service | Tax rules cap a reasonably required reserve at the lesser of 10% of proceeds, maximum annual debt service and 125% of average annual debt service (Treas. Reg. §1.148-2(f)). |
| Reporting | Audited statements within [ ] days; quarterly certificates | The continuing obligations the company signs up to for the life of the bonds. |
| Parties | Bond counsel, trustee, purchaser or placement agent, issuer’s counsel | Each is a fee in the cost of issuance. |
| Closing conditions and timetable | Volume cap, TEFRA approval, opinions, closing by [date] | Cap allocations and TEFRA approvals expire; the timetable must fit both. |
7. What it costs ¶
An IRB carries one-time costs that a bank loan does not: counsel for several parties, the issuer’s fee, the trustee, and the underwriting or placement fee — usually the largest single item. Only 2% of proceeds may pay these costs; the rest comes from the company. Against that, the lower tax-exempt rate applies for the life of the bonds.
| Item | Estimate | Basis |
|---|---|---|
| Issuer application fee | $2K | |
| Issuer’s counsel | $12K | Represents the issuer; reviews documents and the inducement resolution. Some issuers bill part if the deal fails. |
| Volume cap application fee | $1K | Set by each state; see the state’s rules below. |
| Volume cap allocation or closing fee | $2K | Some states charge a share of the allocation or hold a refundable deposit. |
| TEFRA notice publication | $1K | |
| State-level approvals where required | $2K | For example attorney general review (Texas), bond validation (Georgia) or a state commission. |
| Bond counsel | $35K | Drafts the documents and gives the tax opinion; usually contingent on closing, with costs billed if it fails. |
| Borrower’s counsel — documents | $25K | Negotiates the loan agreement, covenants and disclosure on the company’s side. |
| Placement agent’s or underwriter’s counsel | $25K | Drafts the offering memorandum and purchase agreement; often billed on top of the fee. |
| Trustee acceptance fee and trustee’s counsel | $10K | |
| Offering memorandum, printing and posting | $5K | |
| Placement agent fee | $120K | Typical 1.50% of par for this structure: unrated bonds placed with high-yield funds and qualified institutional buyers, usually best efforts. |
| Underwriter’s out-of-pocket expenses | $7K | CUSIP and DTC eligibility, data room, travel, the MSRB assessment ($238 at $0.0297 per $1,000). |
| CUSIP numbers and DTC | $2K | |
| Issuer’s closing fee | $8K | Set by each issuer’s fee policy. |
| Total one-time costs | $258K | 3.22% of par |
| Annual fees (trustee, issuer) | $8K | each year |
Hypothetical illustration, not a quote or a prediction of results. On illustrative assumptions — a 6.40% tax-exempt rate for 20 years against a 7.75% bank loan for 10 years on a 20-year schedule — the bonds’ all-in cost is about 6.96% against 7.92% for the loan, an estimated present-value difference of about $592K in today’s dollars, and the bank loan would leave a balloon of $5.4M to refinance. The break-even size for these assumptions is about $1.9M. Run your own numbers in the calculator.
8. Credit routes ¶
How the bonds are sold depends on the borrower’s size, history and financial statements, and on its banking relationships.
| Route | How it works | Suits | Trade-offs |
|---|---|---|---|
| Bank direct purchase | One bank buys the whole issue and holds it, often with a 7–10 year tender. | $2–15M; strong bank relationship | Lowest cost and fastest; renewal risk at tender; bank covenants. |
| Letter of credit (LOC) | A bank guarantees payment; buyers rely on the bank’s rating. Often variable-rate demand bonds. | Younger companies; thinner financials | Access to money-market buyers and low rates; annual LOC fee (often 1–2%) and renewals. |
| Unrated private placement | Sold to a small group of sophisticated buyers on the company’s own credit, in large denominations. | Established companies with audited statements | Fixed rate to maturity; higher yield than rated paper; limited-offering disclosure. |
| Rated offering | The company (or enhancer) obtains a credit rating and the bonds are sold more broadly. | Larger, investment-grade credits | Widest buyer base; rating and disclosure costs; continuing disclosure obligations. |
9. Credit enhancement ¶
Credit enhancement puts a stronger party’s promise behind the bonds, so buyers rely on it rather than on the company alone. It widens the buyer base and lowers the rate, at the price of fees, collateral and the enhancer’s own covenants.
| Form | How it works | Suits | Trade-offs |
|---|---|---|---|
| Direct-pay letter of credit | The trustee draws on the bank for every payment of principal and interest; the company reimburses the bank under a reimbursement agreement. | Buyers rely on the bank’s rating; standard support for variable-rate bonds. | Annual fee, collateral and covenants to the bank; must be renewed or replaced before it expires. |
| Confirming letter of credit | A larger bank confirms a local bank’s letter of credit, adding its own promise to pay. | When the relationship bank lacks the rating money funds need. | Two banks’ fees; the confirming bank sets its own terms. |
| Standby letter of credit or guarantee | Pays only if the company fails to. | Fixed-rate placements to buyers who want a backstop. | Buyers still analyse the company; less rating benefit. |
| Collateral and reserves | Mortgage, equipment lien and a debt service reserve fund held by the trustee. | Unrated placements on the company’s own credit. | Reserve sizing is capped by tax rules; collateral protects recovery, not timely payment. |
| Bank direct purchase | Not enhancement but the alternative: one bank buys and holds the bonds. | Smaller deals with a strong bank relationship. | Tender or renewal date before final maturity; bank covenants. |
10. Variable-rate demand bonds ¶
A variable-rate demand bond (VRDN) is a long-dated bond that behaves like short-term paper. Its rate resets daily or weekly, and holders may tender (put) the bonds back at par plus accrued interest on short notice — typically seven days for weekly bonds. That demand feature lets money market funds buy them.
- Rate setting. The remarketing agent sets each reset at the lowest rate that sells the bonds at par. Weekly rates follow short-term tax-exempt market conditions; the market’s weekly reference is the SIFMA Municipal Swap Index, whose levels we do not publish.
- Liquidity. If tendered bonds cannot be resold, the trustee draws on the bank’s letter of credit or liquidity facility. Bonds the bank buys become “bank bonds”, carry a higher rate and usually must be repaid over a short term.
- Expiry and mode changes. The letter of credit runs for a set term and must be renewed or replaced; if it is not, or the borrower converts the bonds to a fixed rate, holders face a mandatory tender.
- All-in cost. The reset rate plus the annual letter of credit fee, the remarketing fee and trustee fees. Some borrowers fix the cost with an interest rate swap, which adds its own counterparty, termination and basis risk.
11. Who buys the bonds ¶
Tax-exempt buyers include high-yield and state-specific municipal bond funds, separately managed accounts, banks (often as direct purchasers), insurance companies and, for letter-of-credit-backed variable-rate bonds, money market funds. Securitief tracks 168 conduit issuers whose bonds registered funds hold.
| Conduit issuer | State | Held by funds | Funds holding | Change, 4 quarters |
|---|---|---|---|---|
| Public Finance Authority (Wisconsin; issues nationwide) | WI | $15.4B | 252 | $5.3B |
| Massachusetts Development Finance Agency | MA | $6.8B | 199 | $1.1B |
| New Jersey Economic Development Authority | NJ | $4.7B | 192 | −$540.9M |
| Pennsylvania Economic Development Financing Authority | PA | $4.6B | 190 | $613.7M |
| Florida Development Finance Corp | FL | $4.3B | 93 | −$896.1M |
| South Carolina Jobs-Economic Development Authority | SC | $3.1B | 146 | $120.3M |
| California Infrastructure & Economic Development Bank | CA | $2.9B | 154 | −$833.1M |
| Arizona Industrial Development Authority | AZ | $2.7B | 144 | $862.6M |
| Arkansas Development Finance Authority | AR | $1.6B | 88 | $388.6M |
| Maricopa County Industrial Development Authority | AZ | $1.6B | 144 | $165.7M |
Banks are the other pillar: FDIC-insured banks report $284.9B of municipal securities on their balance sheets in the latest call reports, and many buy small industrial issues directly from borrowers in their market.
12. After closing ¶
- Use the money as approved. Spend proceeds on the facility described in the tax certificate and keep records by category.
- Keep the facility in qualified use. Leases, management contracts or a sale can affect tax status; consult bond counsel first.
- Report to holders. Annual audited statements, covenant certificates and notices of material events, as the documents require.
- Arbitrage and rebate. Track investment earnings on unspent proceeds and reserves; rebate computations are due at least every five years.
- Keep records for the life of the bonds plus three years.
13. Post-issuance compliance calendar ¶
Most loss of tax exemption comes from what happens after closing. The calendar below lists the recurring obligations for a typical small-issue or exempt facility bond; your documents may add more.
| When | What | Rule |
|---|---|---|
| Before closing | Inducement resolution; costs paid from 60 days before it can be reimbursed | Treas. Reg. §1.150-2 |
| Closing | Tax certificate signed; written post-issuance procedures adopted; records file opened | IRC §§141–150 |
| By the 15th day of the second month after the calendar quarter of issue | Issuer files Form 8038 with the IRS | IRC §149(e) |
| Within 10 business days of any listed event | Event notice, if the bonds are subject to Rule 15c2-12 | SEC Rule 15c2-12(b)(5)(i)(C) |
| 6, 12 and 18 months after closing | Check spending against the 18-month exception (15%, 60%, 100%) if it is being used | Treas. Reg. §1.148-7(d) |
| 6, 12, 18 and 24 months after closing | Check spending against the two-year construction exception (10%, 45%, 75%, 100%) if it is being used | Treas. Reg. §1.148-7(e) |
| 2 years after acquiring an existing building | Rehabilitation spending of at least 15% of the bond-financed acquisition cost completed | IRC §147(d) |
| Each year | Audited statements and covenant certificate to the trustee and holders; review use of the facility, leases and contracts | Bond documents; IRC §§141, 144 |
| Through 3 years after closing | Track capital expenditures at the facility and related sites against the $20 million limit (small-issue bonds) | IRC §144(a)(4) |
| Test period: 3 years from the later of issue and placed-in-service | Track every principal user’s outstanding tax-exempt facility bonds against the $40 million limit | IRC §144(a)(10) |
| 5 years after closing, and every 5 years | Rebate computation; installment due within 60 days, with Form 8038-T | Treas. Reg. §1.148-3 |
| Within 60 days after final redemption | Final rebate payment | Treas. Reg. §1.148-3 |
| Life of the bonds plus 3 years | Keep records of spending, use and investments (and of any refunding bonds) | IRS record-keeping guidance |

14. Taxability risk ¶
Interest on the bonds is tax-exempt only while the bonds keep meeting the rules. If they stop, interest can become taxable to holders — for some failures from the date of the event, for others back to the date of issue — and the borrower may lose its interest deduction for the period of non-qualified use (IRC §150(b)). The bond documents usually make a “determination of taxability” an extraordinary redemption event, sometimes with a premium or a higher rate paid to holders.
| Trigger | What it looks like | Safeguard |
|---|---|---|
| Change of use | Leasing or selling the facility to a user that would not qualify, or using it for a non-qualifying purpose. | Remedial action within the rules (Treas. Reg. §1.142-2 for exempt facility bonds), redemption, or a closing agreement. |
| Capital expenditure limit | Small-issue bonds: capital spending at the facility and related sites over the six-year test period exceeding $20 million. | Budget expansions against the limit before committing; bond counsel reviews large purchases. |
| $40 million beneficiary limit | A principal user’s outstanding tax-exempt facility-related bonds exceeding $40 million during the test period. | Check before an owner or affiliate borrows elsewhere. |
| Proceeds spent off-project | Spending on items outside the tax certificate, or more than 25% on land or 5% on non-qualifying costs. | Requisition review against the tax certificate; reallocation within the time limits. |
| Arbitrage and rebate | Investing proceeds above the bond yield beyond the exceptions, or missing rebate payments. | Yield restriction, rebate computations and timely Form 8038-T filings. |
The IRS Office of Tax Exempt Bonds examines issues and offers a voluntary closing agreement programme for violations found and reported by the issuer. Written post-issuance procedures, a named responsible officer and an annual review are the practical defence; the templates page has an outline.
15. Frequently asked questions ¶
Is the issuer liable if the company defaults?
No. The bonds are limited obligations payable only from the borrower’s payments and any collateral or credit enhancement. The issuer lends its tax-exempt status, not its credit.
How much lower is the rate than a bank loan?
It depends on credit, size and term. Because the interest is tax-exempt for most buyers, tax-exempt yields usually sit well below taxable rates for the same credit. Use the cost calculator with your own bank quote to see the all-in difference after fees.
Can I refinance an existing loan with IRBs?
Generally not as new-money bonds: at least 95% of proceeds must finance the qualifying facility. Current refunding of earlier tax-exempt bonds is possible; private activity bonds can never be advance-refunded (§149(d)), and refinancing taxable debt has narrow exceptions. Bond counsel decides.
What if my project is larger than $10 million?
Manufacturing bonds are capped at $10 million per issue under the capital expenditure election ($1 million without it), and capital spending at the facility over the six-year test period must stay within $20 million. Larger projects may qualify under an exempt-facility category, combine tax-exempt and taxable pieces, or use other financing.
Do I need a credit rating?
No. Most small industrial revenue bonds are unrated and sold to sophisticated buyers, purchased by a bank, or backed by a bank letter of credit.
What is the TEFRA hearing?
A public hearing on the proposed bonds, held after at least seven days’ notice, followed by approval from an elected official of the issuer’s jurisdiction (IRC §147(f)). It is usually brief and procedural.
Can I reimburse costs I have already paid?
Yes, if they were paid no more than 60 days before the issuer’s declaration of official intent (the inducement resolution) and are reimbursed within the time limits in Treas. Reg. §1.150-2. Preliminary costs have more flexibility.
What happens if I sell the company?
The bonds usually must be redeemed or assumed by the buyer with consent, and any change in use of the facility needs bond counsel’s review to protect the tax exemption.
Are the bonds subject to the alternative minimum tax?
Interest on private activity bonds other than qualified 501(c)(3) and post-2008 housing bonds is an individual AMT preference item (IRC §57(a)(5)). From 2026 lower phase-out thresholds bring more high-income households into the AMT. The larger cost is the buyer base: AMT-free funds and many separately managed accounts cannot own these bonds, which narrows demand and widens the AMT spread. The corporate AMT was repealed in 2017, so banks and insurers are largely unaffected.
What reporting is required after closing?
Typically annual audited financial statements and a covenant certificate to the trustee and holders, notice of material events, investment and arbitrage records, and an annual confirmation that the facility remains in qualified use.

Methodology and sources
Fund holdings are from SEC Form N-PORT filings of registered investment companies, classified by Securitief as conduit and industrial-type municipal bonds. Bank holdings are municipal securities reported in FDIC call reports. Volume cap figures follow the IRS annual inflation adjustment as compiled by Securitief. Cost estimates use the Securitief cost model with the assumptions stated; they are not quotes. Legal references are to the Internal Revenue Code of 1986, as amended, and Treasury Regulations.
