Qualified Rural Opportunity Funds: The 30% Step-Up

What makes a fund a qualified rural opportunity fund

Section 70421 of Public Law 119-21 added section 1400Z-2(b)(2)(C). As Rev. Proc. 2026-14, section 2.01(4), restates it, a qualified rural opportunity fund is a qualified opportunity fund that holds at least 90% of its assets in zone property that is either business property substantially all of whose use, during substantially all of the fund's holding period, was in a zone comprised entirely of a rural area, or stock or a partnership interest in a zone business whose tangible property is substantially all zone business property used in such a zone.

The rural definition is statutory: any area other than a city or town with more than 50,000 inhabitants and any urbanized area contiguous and adjacent to such a city or town. Notice 2025-50, section 4, applies it with 2020 census data, treating incorporated places and census designated places over 50,000 as the cities and towns, and any Census Bureau designated urban area as an urbanized area. A zone qualifies only if it is comprised entirely of a rural area, so one urban corner disqualifies the whole tract.

The fund is still an ordinary opportunity fund first. It self-certifies on Form 8996, meets the 90% asset test on the last day of its first six months and its year end, and its zone businesses meet the 70% tangible property and 50% gross income tests described in QOF due diligence. The rural label sits on top of all of that.

The 30% step-up in numbers

Under section 1400Z-2(b)(2)(B), an investment held five years gets a basis increase of 10% of the deferred gain, or 30% for an investment in a qualified rural opportunity fund. Rev. Proc. 2026-14 notes that the rural fund provision is effective for amounts invested in funds after December 31, 2026, so money placed in 2026, even in an all-rural fund, has its deferred gain included on the 2026 return with no step-up, as the rolling five-year deferral explains.

Hypothetical, round numbers. You defer a $1,000,000 gain into a rural fund in February 2027 and still hold it in February 2032. Basis rises by $300,000, so $700,000 of deferred gain is included in 2032. In a standard fund the increase is $100,000 and $900,000 is included. At a 20% rate that is $140,000 against $180,000 before the 3.8% net investment income tax and state tax, a $40,000 difference on the same gain. If you sell before the fifth anniversary there is no step-up in either fund. Run your own numbers with your CPA.

The step-up only trims the deferred gain. It does not touch the fund's own appreciation, which the ten-year election under section 1400Z-2(c) addresses separately and which is capped at the value on the thirtieth anniversary for post-2026 money; the ten-year and thirty-year rules cover that.

The 50% substantial improvement rule already applies in rural zones

Section 1400Z-2(d)(2)(D)(ii) now reads that used property is substantially improved when additions to basis during a 30-month period exceed the adjusted basis at the start of the period, or 50% of that basis for property in a zone comprised entirely of a rural area. Section 5 of Notice 2025-50 applies the 50% figure to any determination made on or after July 4, 2025 for property in a 2018 zone that is entirely rural, whether the property is held by the fund or by a zone business.

Hypothetical: a fund buys a $3,000,000 building in a rural zone, with $1,000,000 allocated to land and $2,000,000 to the building. Because land is excluded from the measurement under Reg. section 1.1400Z2(d)-2(b)(4)(iv), the fund must add more than $1,000,000 to the building's basis within 30 months; in a non-rural zone the figure would be more than $2,000,000. The substantial improvement test sets out the land, vacancy and timing rules in full.

This rule does not require the fund to be a qualified rural opportunity fund. Any fund or zone business improving property in an all-rural zone gets the 50% threshold, which is why the rural label matters at the property level as well as the fund level.

Where the rural zones are, and how the 2027 map changes them

Notice 2025-50 identifies 3,309 of the 8,764 zones designated in 2018 as comprised entirely of a rural area and lists them in its appendix. Those designations expire December 31, 2028. For the 2027 round, Rev. Proc. 2026-14 identifies 25,332 eligible low-income tracts, of which 8,334 are entirely rural, and says Treasury's online mapping resource flags the rural ones. The 2027 designation calendar explains the nomination and certification dates.

Section 5 of Notice 2026-40 matters for rural funds raising capital in 2027: tangible property acquired after December 31, 2026 must be for use in a zone designated after July 4, 2025 unless it is bought under a working capital plan adopted by December 31, 2026 or as an ordinary-course replacement. A rural fund marketing a 2027 raise should be able to name its tracts and say whether they are 2027 zones.

What to check before choosing the rural fund

The 30% step-up depends on the fund staying a qualified rural opportunity fund. If its assets drift below 90% in all-rural zones, the statute gives the standard 10% increase instead. Ask how the sponsor tests the rural composition of each tract, what happens if a later acquisition is in a non-rural zone, and how the fund will gather the information its rural zone businesses must furnish under section 6039L, described in OZ fund reporting requirements.

The timing risks are the same as any opportunity fund: the deferred gain comes due in year five whether or not the fund distributes cash, the ten-year exclusion requires the fund to still qualify at the sale, and the interest is illiquid in between. For a real estate gain where you can reinvest the full price, a 1031 exchange avoids the five-year bill altogether; 1031 versus an opportunity fund versus paying the tax compares them.
