The Rental Grouping and Aggregation Elections Explained

TL;DR: By default, each rental property is a separate activity for the passive loss rules. Real estate professionals can elect to treat all rental real estate interests as one activity, which makes material participation far easier but means selling one property is no longer a full disposition. The election is binding for later years and needs a statement; late relief exists.

Educational only, not tax, legal, or investment advice. Examples are illustrations, not predictions. Rules and limits change; verify current figures and talk to a qualified professional about your situation.

Your tenant pays the mortgage; the IRS pays for the roof over 27.5 years. If you own several rentals, the IRS also wants to know whether you own one activity or five. The answer drives material participation, real estate professional status and what happens to suspended losses on a sale.

Two different rules get called "grouping." The first is the general grouping rule in Regulations section 1.469-4, which lets taxpayers treat activities that form an appropriate economic unit as one activity. The second, and the one most landlords mean, is the election for real estate professionals under section 469(c)(7)(A) and Regulations section 1.469-9(g) to treat all interests in rental real estate as a single rental real estate activity. Pub. 925 points to the Schedule E instructions and Regulations section 1.469-9(g)(3) for that election. This guide covers both, focusing on the second.

CPA Warning Label: The aggregation election is a one-way door for most people. It helps you qualify today and can delay releasing suspended losses when you sell a property years later.

Why each rental is separate by default

For a real estate professional, section 469(c)(7)(A) says each interest in rental real estate is treated as a separate activity unless the taxpayer elects otherwise. Pub. 925 repeats it: each interest in rental real estate is generally a separate activity unless you elect to treat all interests as one.

That default is harsh. A real estate professional with five rentals would need to materially participate in each one separately: for example, more than 500 hours in each, or more than 100 hours and not less than anyone else in each. Hours spent on one property do not help another. Many taxpayers who pass the 750-hour test overall fail material participation property by property.

The election solves that by putting all the hours in one bucket. If the combined activity meets a material participation test, all the rentals are nonpassive.

How to elect

The REPS aggregation election is made by filing a statement with your original income tax return for the year. The statement declares that you are a qualifying taxpayer for the year and are making the election under section 469(c)(7)(A) to treat all interests in rental real estate as a single rental real estate activity. Practical points:

• Make it in a year you qualify as a real estate professional; it has effect only in years you qualify.
• It is binding for that year and all future years in which you are a qualifying taxpayer, even if you do not qualify in some intervening years. The Tax Court noted this in Moss v. Commissioner, citing Regulations section 1.469-9(g).
• It can be revoked only in a year of a material change in facts and circumstances.
• It covers all interests in rental real estate, including rentals held through partnerships in many cases, subject to special rules for limited partnership interests.
• Keep a copy of the original statement permanently.

The separate general grouping rules of section 1.469-4 also require disclosure. Rev. Proc. 2010-13 requires taxpayers to report new groupings, additions to existing groupings and regroupings with a written statement attached to the return.

What the statement can look like

There is no IRS form for the aggregation election; it is a statement. A typical version, adapted to your facts and attached to the original return, reads along these lines:

Election under section 469(c)(7)(A) and Regulations section 1.469-9(g). The taxpayer, [name, TIN], is a qualifying taxpayer under section 469(c)(7)(B) for the tax year ending December 31, 2026, and hereby elects to treat all interests in rental real estate as a single rental real estate activity.

Tax software often has a checkbox that generates a statement like this, but confirm it actually printed with the filed return; a checkbox that was never transmitted is not an election. Joint filers should make sure the statement reflects the qualifying spouse. Save a copy of the filed statement with your permanent property records, not just with that year's return, because you may need to prove the election years later when the binding effect matters or when you sell.

Late election relief

Forgot to file the statement? Rev. Proc. 2011-34 provides a simplified procedure for late aggregation elections under section 1.469-9(g) for taxpayers who meet its requirements, generally including that they filed consistently as if they had made the election and had reasonable cause for failing to make it. The relief is obtained by filing a statement with an amended return for the most recent tax year, with the required declarations.

If the requirements are not met, a private letter ruling may be needed. Do not assume relief is automatic; confirm eligibility against the revenue procedure itself.

Downsides of grouping

• Suspended losses on sale. Losses are released when you dispose of your entire interest in an activity. If all rentals are one activity, selling one property is a partial disposition, and its suspended losses generally stay suspended unless the sale is substantially all of the activity and you can prove the allocable amounts with reasonable certainty (Pub. 925). See suspended passive losses.
• Binding in later years. You cannot pick and choose by year.
• Prior suspended losses. Losses suspended before you elected keep their character as losses from former passive activities and are used against income from the activity under special rules; the election does not unlock them immediately.
• Limited partnership interests. Including them can make material participation harder for the combined activity, under special rules for limited partners.
• No benefit if you are not a REPS. The election only applies in years you qualify.

Illustration: A real estate professional has three rentals with $45,000 of total suspended losses from years before qualifying, aggregated in 2026. In 2028 she sells one property. Without aggregation, that sale would release the property's own suspended losses. With aggregation, it is a partial disposition of one activity, and release generally waits until she sells substantially all the rentals, unless the partial disposition exception applies.

Interaction with STRs

A short-term rental with an average customer use of 7 days or less is not a "rental activity" for section 469 purposes. It is treated as a trade or business, and its losses are nonpassive if you materially participate in it, without needing REPS. That has consequences:

• The REPS aggregation election covers interests in rental real estate; an STR that is not a rental activity is generally outside that election.
• Grouping an STR with long-term rentals under the general grouping rules is restricted, because rental activities generally cannot be grouped with trade or business activities unless one is insubstantial relative to the other or ownership is identical, under Regulations section 1.469-4(d).
• Most STR owners therefore test material participation in each STR separately, which favors owners who self-manage one or two properties.

See the short-term rental tax guide for the 7-day test.
