For high-income entrepreneurs and professionals, the “Holy Grail” of tax planning is finding a way to use large rental losses often generated by cost segregation and bonus depreciation to offset active income from a W-2 job or a separate business. This approach can help you feel more confident in your tax strategy and empowered to reduce your tax burden effectively. While the IRS generally traps rental losses in the “passive” bucket, Treasury Regulation provides a powerful mechanism to bridge that gap. By making a formal Grouping Election, you may be able to treat your short-term rental (STR) and your primary business as a single “appropriate economic unit,” thereby bypassing the passive activity loss limitations entirely.
If you are ready to stop leaving thousands of dollars in “suspended losses” on the table and want to see if your portfolio qualifies for grouping, we are ready to build a strategy for you. Contact us to schedule a strategy session today!

The Power of the "Appropriate Economic Unit"
The IRS allows you to group multiple trade or business activities into a single activity if they form an "appropriate economic unit". This is a "facts and circumstances" test, meaning there is no one-size-fits-all answer, but the more integrated your businesses are, the stronger your case becomes. Understanding these criteria can help you feel more secure in your decision to pursue grouping, knowing it's a legitimate and supported strategy.
The Five Factors the IRS Looks For:
For an STR owner, this might look like grouping a property management company with the rentals, or grouping a consulting business with a "corporate retreat" STR that the business uses frequently.
Unlocking Active Losses via Material Participation
The primary reason to group is to meet the Material Participation requirements more easily. If you have a primary business where you work 1,000+ hours a year and you group your STR with it, the "active" status of your primary work can potentially "bleed over" to the rental.
Once grouped, the STR is no longer a separate "passive" activity. This means the large paper losses generated by a Cost Segregation Study, which can often reach 25-30% of the property value, can be used to lower the taxable income of your main business directly. In 2026, with 100% bonus depreciation fully restored under the One Big Beautiful Bill Act, this grouping strategy can result in a $0 tax bill for many profitable business owners.

The Risks: The "One-Way Street" Rule
A grouping election is a 'married for life' decision. Once you group activities, you cannot ungroup them in future years unless there is a 'material change in facts and circumstances' or the original grouping was clearly erroneous, so consider your long-term plans carefully.
Strategic Considerations Before Grouping:
Reporting Requirements: You must attach a formal statement to your tax return in the first year you group the activities, including details of the entities involved and the economic interdependence. If you forget this statement, the IRS can disallow the grouping and reclassify your losses as passive, so proper documentation is essential.
Best Practices for Audit-Proof Grouping
To survive an IRS challenge, your grouping must be more than just a "tax play"; it must make operational sense.

Frequently Asked Questions
Can I group my STR with my W-2 job?
No. You can only group' trade or business' activities, such as LLCs or sole proprietorships. Since being an employee is not considered a trade or business for §1.469-4, you cannot group a rental with a W-2 salary, but active businesses like LLCs or partnerships are eligible.
Does each business need to be in an LLC?
The IRS grouping rules apply to the activities regardless of the legal entities involved. You can group a Sole Proprietorship with an LLC, or two separate S-Corps, as long as the ownership and control requirements are met.
Can I group a Long-Term Rental with an STR?
Generally, no. The IRS has strict rules against grouping "rental activities" with "non-rental trade or business activities" unless one is "insubstantial" in relation to the other. However, since an STR (stay < 7 days) is often not a "rental activity" by definition, it is much easier to group with another business.
What happens if I sell one property in a grouped portfolio?
Because they are treated as one activity, the sale of one property is considered a "partial disposition." You may not be able to claim the suspended losses until the entire grouped activity is sold or disposed of.
Need help reviewing your grouping election strategy?
Grouping a short-term rental with another active business can unlock major deductions, but it is not a casual checkbox. The businesses need a real economic connection, clean participation records, a timely election statement, and a long-term exit plan that accounts for suspended losses and future sales. We help entrepreneurs evaluate whether grouping makes sense, document the appropriate economic unit, and build an audit-ready file before the return is filed.
