Pooled Income Fund: How They Work, Tax Deduction, and When to Use One

Not tax or legal advice — pooled income fund suitability depends on your age, the specific fund's performance history, asset type, and charitable goals. Exact deduction calculations require IRS actuarial tables (IRS Pub. 1458) and are best verified with a charitable planning specialist.

A pooled income fund sits between a charitable gift annuity and a charitable remainder trust on the complexity spectrum. Like a CGA, it is managed by the charity — you don't hire a trustee or draft a trust document. Like a CRT, your contribution goes into an investment account and you receive a share of the earnings. Unlike either, your income is entirely variable: it rises when the fund performs well and falls when it doesn't.

Pooled income funds were common at universities, hospitals, and religious institutions throughout the 1990s. They fell out of favor during the low-rate era (2010–2022) when fund returns compressed income to near-zero. With rates now meaningfully higher, PIFs have re-emerged as a viable option for donors who want an income stream tied to investment performance rather than a fixed rate — and who have a deep relationship with one specific institution.

What a pooled income fund is

A pooled income fund is a split-interest trust defined under IRC §642(c)(5).¹ Each donor makes an irrevocable contribution of cash or property, transferring a remainder interest in that property to a qualifying public charity while retaining a lifetime income interest. The charity combines all donors' contributions into a single pooled investment fund — hence the name.

Key structural requirements under §642(c)(5):

• The fund must be maintained by a public charity (IRC §170(b)(1)(A)) — not a private foundation, donor-advised fund, or supporting organization.
• The charity cannot be a donor or income beneficiary of the fund; it only receives the remainder.
• No donor, income beneficiary, or person with substantial control over the fund may serve as trustee.
• Contributions are commingled — your proportionate share, not your specific assets, earns income.
• The fund cannot invest in tax-exempt securities (municipal bonds), because the income must be fully taxable ordinary income to beneficiaries.

How pooled income fund income works

Each year, the fund distributes all of its investment income to current income beneficiaries in proportion to their share of the fund's total value. "Investment income" means dividends and interest — not capital gains, which remain in the corpus.

What this means in practice:

• Income is variable. If the fund earns 6% in one year and 3% the next, your income moves accordingly. There is no guarantee of any minimum payment, unlike a CGA's fixed rate or a CRAT's fixed payout amount.
• Income is ordinary income. All distributions from a pooled income fund are taxable as ordinary income at your marginal rate. There is no partially tax-free return-of-principal component (as with a CGA) and no capital gains character (as with a CRT in four-tier ordering).
• Capital gains stay in the fund. When the fund sells appreciated securities to rebalance or reinvest, the gain is allocated to corpus — not distributed to income beneficiaries. This gain is not currently taxable to you or to the fund (amounts permanently set aside for the charitable remainder are deductible to the fund under IRC §642(c)).¹
• Income continues for your life (or the lives of named income beneficiaries). At death, your share of the fund corpus passes outright to the charity — free of estate tax under IRC §2055.²

Charitable deduction calculation

You receive a charitable income tax deduction in the year you fund the pooled income fund, equal to the fair market value of your contribution minus the present value of the income interest you retain. The IRS calculates that present value using actuarial tables from IRS Publication 1458 (Table H), applying a discount rate equal to the highest rate of return earned by the fund in any of the three most recent taxable years.¹

Two implications of this rule:

• Higher fund returns reduce the deduction. If the fund has earned 8% in recent years, the income stream you retain has a higher present value, leaving a smaller charitable remainder — and a smaller deduction. Lower recent returns produce larger deductions. This is the inverse of how CGA and CRT work, where higher §7520 rates increase the deduction.
• New funds use a fixed rate. If the fund has been in existence for fewer than three taxable years, the applicable rate is 6% per annum (unless the IRS has prescribed a different rate under the regulations).¹

The deduction is also subject to the standard AGI limits — 30% of AGI for long-term appreciated property, 60% for cash — with a 5-year carryforward for excess amounts. The OBBBA (2025) added a 0.5% AGI floor (the first 0.5% of AGI of total charitable deductions is disallowed) and a 35% value cap for donors in the 37% bracket.³

Funding with appreciated stock

Appreciated stock (held more than one year) contributed to a pooled income fund receives favorable treatment:

• No capital gains at contribution. You do not recognize the built-in gain when you transfer appreciated shares into the fund — unlike selling the shares and donating cash.
• Deduction at fair market value. Your deduction is based on the full FMV of the contributed shares, not your cost basis.
• Fund sells without capital gains distribution to you. When the fund liquidates the contributed shares to invest in the pooled portfolio, the gain remains in corpus and is not taxed to you currently. Capital gains that are permanently set aside for the charitable remainder are deductible to the fund.¹

Unlike a CRT, the capital gain does not eventually "pass through" to you in later years as four-tier income. It stays in the corpus and ultimately benefits the charity. For a donor whose primary goal is capital gains avoidance and a charitable deduction — not re-accessing the capital gains as income — this can be advantageous.

Practical limit: 30% AGI cap on appreciated property. Contributions of appreciated stock or real estate to a pooled income fund are subject to the 30% of AGI limit (same as for CRTs and CRUTs). Excess amounts carry forward for up to five years.

Pooled income fund vs. CGA vs. CRT vs. DAF

When a pooled income fund makes sense

PIFs fit a narrow but real set of donor circumstances:

• Deep relationship with one institution. Alumni who want to give back to their university, major donors to a hospital system, or parishioners supporting a religious organization. The one-charity constraint is a feature, not a bug, when you have a clear giving intention.
• Smaller gift size where a CRT is impractical. A custom CRT requires attorney fees, trustee fees, and ongoing administration — often not worth it below $250,000–$500,000. A pooled income fund can work for gifts as small as $10,000–$25,000, with the charity absorbing the administrative cost.
• Appreciated stock you want to diversify without capital gains. Contributing appreciated shares that the fund will sell and reinvest avoids immediate capital gains recognition, with the gain staying in corpus (permanently) rather than coming back to you as four-tier income (as it would in a CRT).
• Preference for market-linked income. Some donors prefer variable income that can grow if the fund performs well, rather than a fixed CGA rate that may lag inflation over decades.
• Supplement to direct bequests. Donors who plan to leave the majority of their estate to an institution can use a PIF to establish a lifetime income stream from a portion of their assets now, while retaining flexibility elsewhere.

When a pooled income fund is not the right choice

• You need predictable income. If you rely on the payments to cover living expenses, a CGA's fixed rate is far more suitable. PIF income can drop significantly in a down market.
• You want to give to multiple charities. A DAF is almost always better — it provides a full FMV deduction, full capital gains avoidance, and the ability to grant to any 501(c)(3).
• The institution doesn't maintain a PIF. Many charities stopped maintaining PIFs during the low-rate era and never restarted. Before planning around a PIF, confirm the institution actively maintains one and can accept your proposed asset type.
• You have highly appreciated illiquid assets (real estate, closely held stock). A custom CRT is better suited because the trustee can manage the complex sale; pooled income funds typically accept only cash and publicly-traded securities.
• You want capital gains to return to you as income. A CRUT distributes capital gains in the four-tier ordering — eventually passing tax-favorable capital gain income back to you. A PIF keeps those gains in corpus permanently. If converting capital gains into income is part of the plan, a CRT is more effective.

Who currently offers pooled income funds

Pooled income funds are offered directly by the charities that maintain them — not through DAF sponsors or third-party platforms. Institutions that typically offer PIFs include:

• Research universities — Harvard, Stanford, MIT, University of Chicago, and most major research institutions maintain PIFs for alumni giving.
• Hospital systems and academic medical centers — Major hospitals and health system foundations often maintain PIFs alongside CGAs.
• Religious organizations — National Catholic Community Foundation, Jewish Federations, and many denominational foundations offer PIFs as planned giving vehicles.
• Community foundations — Some community foundations maintain pooled income funds alongside their donor-advised fund programs.

To confirm whether a specific institution offers a PIF, contact their planned giving or gift planning office (sometimes called the "office of gift planning" or "development office"). Ask about the fund's current applicable rate (highest of the last three years) and minimum gift threshold.

Common mistakes

• Assuming income is fixed. Donors sometimes confuse PIFs with CGAs. The income is entirely variable — there is no guarantee of any minimum distribution amount.
• Contributing to a fund with poor performance without understanding the deduction impact. A fund with a very low 3-year return produces a deduction based on a low applicable rate, which actually translates to a larger deduction per dollar contributed (because the income stream's present value is smaller). But you'll also receive lower income. Model both the deduction AND expected income before contributing.
• Overlooking state income tax on PIF income. All PIF income is ordinary income — fully taxable at your state rate. This contrasts with CGAs, where the return-of-principal component is state-tax-free in most states.
• Expecting broad grantmaking.< /strong> PIF remainder goes to the maintaining charity only. If your charitable interests evolve, you cannot redirect the remainder to a different organization.
• Ignoring the institutional risk. If the charity dissolves or merges, the PIF's governing instrument must specify what happens to the fund. Confirm the institution's financial stability and the governing instrument's successor provisions before contributing.
• Contributing highly appreciated illiquid assets without confirming acceptance. Most PIFs accept only cash and publicly traded securities. Unlike a CRT (where you can appoint a trustee capable of handling complex assets) or a DAF sponsor with complex-asset acceptance, PIFs are rarely equipped to receive real estate, closely-held stock, or cryptocurrency.
