Passive Activity Loss Grouping Election Calculator (2026)
Under IRC 469, passive losses can only offset passive income. Grouping multiple activities into one 'appropriate economic unit' can let you meet material participation hours collectively — turning a passive loss into a deductible active loss.
| Combined hours (A + B) | — |
| Material participation if grouped (500 hr test) | — |
| Combined net loss/income | — |
| Deductible if grouped (active loss) | — |
| Deductible if separate (passive limited) | — |
| Tax saved by grouping | — |
Under IRC Section 469, passive activity losses can only offset passive activity income. Losses from a single business in which you don't materially participate (typically less than 500 hours/year) get suspended until you have passive income or dispose of the activity. The grouping election under Treasury Regulation 1.469-4 lets you combine multiple related activities into one 'appropriate economic unit' so combined hours satisfy material participation — converting passive losses into deductible active losses.
When Grouping Helps
Three common scenarios. (1) Multiple rental properties: real estate professionals who own several rentals can group them so combined participation hours qualify. (2) Service business + owned real estate: a dentist with a consulting LLC who also owns the building rented to the LLC can group them, converting the rental from passive to active. (3) Multiple S corps in related trades: several restaurant locations under one S corp umbrella can be grouped if they share supply chain, management, or customer base. Grouping is most powerful when one activity has losses and the other has profits — combined material participation makes the losses fully deductible.
Grouping Traps To Avoid
(1) Disposition trap: suspended losses are released only when the ENTIRE grouped economic unit is disposed. Sell one property in a 5-property grouped portfolio and nothing releases. If you plan to sell individual properties, don't group. (2) Cannot ungroup without IRS consent: once filed, grouping is generally binding unless material change occurs. Get the choice right the first time. (3) Appropriate economic unit test: groupings must share organizational, economic, or operational ties. Random unrelated activities cannot be grouped (mineral rights with retail store, for example). (4) Disclosure required: file Form 8582 disclosure when the grouping is first made and when activities are added or removed. Failure to disclose can trigger IRS regrouping at audit, often unfavorable. Document your grouping rationale in writing at the time of election.
