Aggregation Election for Real Estate Pros: 1.469-9(g) Explained
The aggregation election lets a qualifying real estate professional treat every rental property as one rental activity. It comes from Reg. §1.469-9(g), and for most pros with more than one or two buildings it is the difference between their rental losses offsetting other income and those losses sitting on Form 8582. It is made by a statement on the original return, it binds future years, and it has a real cost when you start selling buildings one at a time.
If you have not yet read how real estate professional status works, start with real estate professional status: the 750-hour test. This article assumes you qualify.
Why the election exists
Qualifying as a real estate professional (REP) under §469(c)(7) does not, by itself, make your rentals nonpassive. Reg. §1.469-9(e)(1) says a REP's rental "is a passive activity under section 469 for the taxable year unless the taxpayer materially participates in the activity," and then:
"Each interest in rental real estate of a qualifying taxpayer will be treated as a separate rental real estate activity, unless the taxpayer makes an election under paragraph (g) of this section to treat all interests in rental real estate as a single rental real estate activity."
Without the election, you must pass a material participation test for each property. Twelve houses at 60 hours each is 720 hours of work, yet no single house clears the 500-hour test. With the election, all 720 hours count toward one activity.
The Tax Court shows the difference in practice:
- Leyh v. Commissioner, T.C. Summ. Op. 2015-27. The wife was the qualifying taxpayer, kept a contemporaneous log, and had made the aggregation election. The couple won. (A summary opinion, not precedent.)
- Kosonen v. Commissioner, T.C. Memo. 2000-107. An airline pilot with seven properties logged 877 and 977 rental hours in two years, but the court held he had not made the election and there was no evidence of hours per property. He lost.
- Windham v. Commissioner, T.C. Memo. 2017-68. A stockbroker with 12 rentals won REP status, but without the election each property was tested separately. She passed on most and failed on a vacant lot.
How to make the election
Reg. §1.469-9(g)(3) sets the mechanics:
"A qualifying taxpayer makes the election to treat all interests in rental real estate as a single rental real estate activity by filing a statement with the taxpayer's original income tax return for the taxable year. This statement must contain a declaration that the taxpayer is a qualifying taxpayer for the taxable year and is making the election pursuant to section 469(c)(7)(A)."
Points the cases and the regulation make clear:
- A statement is required. Reporting all properties on one Schedule E is not an election (Kosonen; Windham).
- Any year you qualify. "The failure to make the election in one year does not preclude the taxpayer from making the election in a subsequent year" (Reg. §1.469-9(g)(1)).
- It binds. The election "is binding for the taxable year in which it is made and for all future years in which the taxpayer is a qualifying taxpayer ... even if there are intervening years in which the taxpayer is not a qualifying taxpayer" (Reg. §1.469-9(g)(1)).
- Revocation needs a material change. Under Reg. §1.469-9(g)(2), the election being "less advantageous to the taxpayer in a particular taxable year is not, of itself, a material change," and neither is a break in REP status.
The election does not decide whether you are a REP. IRS Chief Counsel said so in CCA 201427016 (dated April 28, 2014): qualification "is not affected by an election under Treas. Reg. §1.469-9(g)." A CCA is not precedent, but it matches the structure of the regulation: REP status is the hours test in §469(c)(7)(B); the election only decides how many activities you have.
Forgot to make it? Rev. Proc. 2011-34
An older IRS training guide told examiners the election "cannot be made on an amended return or during an audit." Rev. Proc. 2011-34 changed that by giving late-election relief. Its conditions, in summary:
- You failed to make the election solely because you did not meet the (g) filing requirements.
- You filed returns consistent with having made the election for every year it would have applied.
- Your returns were timely (filed within 6 months of the due date counts).
- You have reasonable cause for the failure.
- You attach a statement, signed under penalties of perjury, to an amended return for the most recent year, headed "FILED PURSUANT TO REV. PROC. 2011-34."
Read the revenue procedure itself before relying on it: Rev. Proc. 2011-34 (IRB 2011-24).
The cost: selling one building is not selling the activity
This is where the election bites sellers. Reg. §1.469-9(e)(1) continues:
"Each separate rental real estate activity, or the single combined rental real estate activity if the taxpayer makes an election under paragraph (g), will be an activity of the taxpayer for all purposes of section 469, including the former passive activity rules under section 469(f) and the disposition rules under section 469(g)."
Section 469(g) releases suspended losses when you dispose of your entire interest in an activity in a fully taxable sale to an unrelated buyer. (The full release rules are in suspended passive losses when you sell a rental.) Once all your rentals are one activity, selling one building is only part of that activity. The general partial-disposition relief in Reg. §1.469-4(g) applies only "in which there is a disposition of substantially all of an activity."
Suspended losses can still exist for a REP. Losses from years before you qualified, or years you missed the tests, stay on Form 8582. Those are the ones the election can trap.
Simple example (2026 married filing jointly, federal only). A REP couple owns five buildings under the election and carries $200,000 of suspended losses from years before they qualified. Their other taxable income is $600,000.
| Sale | Activity disposed of? | Losses released under §469(g) |
|---|---|---|
| Sell building 1 of 5 | No, one-fifth of the combined activity | Generally none |
| Sell all five in one year | Yes, entire interest | All $200,000 |
If the $200,000 were released against ordinary income, federal tax would drop from $147,538 to $81,196, a $66,342 difference, mostly at the 35% and 32% brackets. Leaving that locked because of a one-building sale is a real cost. It is also why the election is a decision to make with your exit plan in view, not only this year's return.
Grouping versus aggregation
People use the words loosely. They are different rules.
| Grouping, Reg. §1.469-4 | Aggregation election, Reg. §1.469-9(g) | |
|---|---|---|
| Who | Any taxpayer | Only a qualifying REP |
| Test | "Appropriate economic unit," facts and circumstances (common control, ownership, location, interdependence) | Election; no economic-unit test |
| Covers | Trade or business and rental activities, with limits on mixing rental and business | All interests in rental real estate |
| Change later | No regrouping unless clearly inappropriate or facts change materially (Reg. §1.469-4(e)) | Revoke only on a material change (Reg. §1.469-9(g)(3)) |
| At sale | Grouped activity is one activity for §469(g) | Combined activity is one activity for §469(g) |
Reg. §1.469-4(h) points REPs to §1.469-9 for rental real estate. A rental and your own operating business are a separate question, covered in the self-rental rule.
California ignores the whole thing
California does not follow §469(c)(7). R&TC §17561(a) says the federal REP rule "shall not apply," and the FTB 3801 instructions say "all rental activities are passive activities." So the aggregation election is a federal tool. Your California return will still show passive rental losses, and your California suspended loss balance will differ from the federal one.
Bottom line
For a qualifying real estate professional with several properties, the aggregation election is often what makes material participation achievable. Make it with a statement on the original return, or use Rev. Proc. 2011-34 if you missed it and qualify. Before you make it, map your exit: under the election, selling one building usually does not release old suspended losses. The free book covers how pros who retire or sell in stages handle that timing, and material participation for rentals covers the seven tests.
Questions to ask your CPA
- Have I ever filed an aggregation election statement, and in which year's return is it?
- If not, do I meet every condition in Rev. Proc. 2011-34 for late relief?
- How much of my Form 8582 balance comes from years before I qualified as a REP?
- If I plan to sell buildings one at a time, which sales, if any, would release suspended losses?
- Is there a material change in my facts that would allow revocation, and would revoking help?
- What does my California passive loss picture look like, since California does not recognize REP status?
