Limited partnerships (LPs) are a common way to bring investors into a business or real estate venture. If you invest as a limited partner, you generally get two attractive benefits:
- Liability protection: your personal liability is typically limited to your investment (your capital contribution plus any additional required contributions).
- Potential self-employment tax advantage: your share of partnership income may be excluded from self-employment tax in some situations.
However, there’s a tax issue that can materially change the after-tax economics of the investment: the passive activity loss (PAL) rules. These rules can prevent you from using partnership losses when you expect to—sometimes for years.
Why the PAL rules matter to limited partners
The PAL rules limit when you can deduct passive losses. For many limited partners, the partnership activity is treated as passive by default unless an exception applies.
If your LP investment is passive, you can generally deduct losses only to the extent you have passive income from:
- that limited partnership, and/or
- other passive activities you own.
If you don’t have enough passive income, the losses are not deductible in the current year.
Suspended passive losses: what happens when you can’t deduct them
Losses that can’t be deducted because of the PAL rules become suspended passive losses. They carry forward and may become deductible later when either:
- You generate passive income in a future year (from this partnership or other passive activities), or
- You sell or otherwise dispose of your entire interest in the loss-producing limited partnership in a taxable transaction (often the point when suspended losses are “released”).
For middle-market owners, this is a key planning issue: projected tax losses may not reduce current-year tax if you don’t have passive income to absorb them.
Rental real estate is a common PAL trap
With limited exceptions, rental activities are generally treated as passive regardless of how involved you are. So if you invest as a limited partner in an LP that owns rental properties, PAL limitations often apply—meaning losses may be suspended even if the venture is economically sound.
PAL rules aren’t the only limits on deducting losses
Even if PAL rules allow a deduction, other rules can still limit whether and when losses are deductible, including:
- basis limitations (do you have enough tax basis to claim the loss?),
- at-risk rules (are you economically at risk for the amount being deducted?), and
- for noncorporate taxpayers, the excess business loss limitation.
In practice, multiple limitations can apply at the same time, so it’s important to model the expected tax result—not just the projected book loss.
Can limited partners ever treat losses as nonpassive? Yes—if material participation applies
If the LP activity is nonpassive, losses may be deductible against other income (subject to other limitations). To get nonpassive treatment, you generally must materially participate.
But limited partners have a narrower path than general partners. A limited partner is treated as materially participating only if at least one of these tests is met:
- 500-hour test: you participate in the activity for more than 500 hours during the tax year.
- 5-of-10 test: you materially participated in the activity for any 5 of the 10 immediately preceding tax years (consecutive or not).
- Personal service activity test: you materially participated in a personal service activity for any 3 prior tax years (consecutive or not).
A personal service activity generally involves certain professional service fields or other businesses where capital is not a material income-producing factor.
Spousal rule: if you’re married, your spouse’s participation is treated as your participation for these tests—regardless of ownership or filing status.
Dual-status partners: holding both general and limited interests
If you hold both a general partner and limited partner interest in the same activity, you’re typically treated as a general partner for applying material participation rules. That can matter because general partners can qualify under additional material participation tests beyond the three listed above.
This treatment generally depends on whether the general partner interest was held throughout the relevant period (special timing rules can apply if ownership changes during the year).
Two types of “participation” that may not count
Even if you spend time on the business, not all hours necessarily count toward material participation. Two common problem areas are:
1) Work not customarily performed by an owner
If the work you perform isn’t the type normally done by an owner—and one principal purpose is to avoid PAL limits—those hours may not count.
2) Investor-type work (unless you’re involved in day-to-day management)
Time spent purely as an investor generally doesn’t count unless you have day-to-day involvement in operations or management. Activities that often don’t qualify include:
- reviewing financial statements or operating reports,
- preparing analyses for your own use, and
- monitoring the business in a nonmanagerial capacity.
Bottom line: model the after-tax result before you invest
Limited partnerships can be a smart structure for liability protection and investment flexibility. But if you’re investing expecting near-term tax deductions, the PAL rules can delay those benefits by turning current losses into suspended losses.
Before you commit capital—or file a return reporting partnership losses—confirm whether the activity will be passive, whether material participation is realistic, and how other loss limitation rules may affect timing.
What about LLCs taxed as partnerships?
LLCs taxed as partnerships can provide limited liability similar to LPs. However, court decisions have indicated that LLC members aren’t always automatically treated as limited partners for PAL purposes.
As a result, LLC members may be able to use a broader set of material participation tests (similar to general partners), potentially making it easier to achieve nonpassive treatment—depending on the member’s actual involvement.
This PAL discussion is separate from the self-employment tax treatment of LLC members, which should be evaluated independently.
