Infrastructure

What it is

Infrastructure means the physical systems and facilities that economies run on: power generation and transmission, midstream energy, water and waste utilities, toll roads, airports, rail, and increasingly the digital layer — data centres, fibre networks, and communication towers. Returns come predominantly from contracted or regulated cash flow over long periods rather than from a sale, which gives the category a different risk shape from private equity. It is commonly grouped with private equity, private credit, and real estate as one of the four core private-market exposures.

Holding it in a self-directed IRA

The account holds the interest, not you. Most commonly that is a limited-partner interest in an infrastructure fund, a membership interest in a project-level LLC, or a unit in a syndication. Subscription documents are executed in the name of the account — for example Investor Services, Custodian FBO Jane Doe IRA — and every distribution returns to the account. We hold the interest and the records, process the capital calls you direct, and report the value annually. We do not evaluate or approve the investment.

Requirements

• The interest is titled in the account’s name, never your personal name. See titling.
• Subscription documents, side letters, and the operating agreement are provided to the custodian for the file.
• All capital calls are funded from the account, and all distributions are paid to the account.
• An annual fair-market valuation is supplied by the sponsor or a qualified third party.
• The sponsor and every affiliate must not be a disqualified person with respect to the account.

Limitations and prohibitions

• Neither you nor a disqualified person may provide services to the project — engineering, construction, operations, or management — which would be a prohibited transaction under IRC § 4975.
• Infrastructure vehicles are typically leveraged at the asset level, and debt-financed income flowing to an IRA can generate UDFI and UBIT. This is the single most common surprise in this asset class.
• Capital calls arrive on the sponsor’s schedule, not yours; an account without sufficient uncalled cash risks default and forfeiture of the interest.
• Fund lives of ten to fifteen years or longer may extend past the account holder’s required beginning date.
• You may not personally use the asset — no preferential access, no side arrangements.

Valuation and liquidity

Interests are carried at the value the sponsor reports, adjusted at year end for the Form 5498 filing. There is generally no secondary market, so plan on holding to realisation; some funds permit transfers with consent and typically at a discount. For accounts approaching required distributions, illiquidity is the operative constraint — taking RMDs when the account is illiquid covers the mechanics, and the practical answer is usually to hold cash or a liquid position alongside.

Tax considerations

Inside a retirement account, contracted income compounds without current tax, which pairs naturally with a twelve-year asset. The exception is material: to the extent the vehicle produces income financed by debt, the account may owe UBIT on the debt-financed portion and must file Form 990-T. Many infrastructure funds also generate depreciation that reduces the taxable amount — but the filing obligation belongs to the account and is paid from the account. Ask the sponsor, in writing and before subscribing, whether the vehicle expects to issue a K-1 reporting unrelated business taxable income.

A worked example

IRS forms & records

• Form 5498 — annual fair-market value of the interest.
• Schedule K-1 — issued by the vehicle to the account, including any unrelated business taxable income.
• Form 990-T — filed by the custodian for the account when UBIT applies.
• Form 1099-R — distributions from the account.

Common mistakes that can cost you

Before you invest

• The vehicle’s expected use of leverage, and its UBIT/UDFI answer, are in writing.
• The full commitment and call schedule fit the account’s cash, with reserve to spare.
• The sponsor supplies annual valuations without prompting.
• Fund term, extensions, and transfer provisions are understood.
• No disqualified person is involved on either side. Run the checker.

Authorities

• IRC §§ 511–514 — unrelated business income tax and debt-financed income.
• IRC § 4975(c) and (e)(2) — prohibited transactions and disqualified persons.
• IRS Form 990-T instructions — filing by a custodian on behalf of an IRA.
• IRS Form 5498 instructions — annual fair-market value reporting.
