Schedule K-1 (Form 1065) is a key tax document that reports your share of income, deductions, credits, and other tax-related items from partnerships, S corporations, or trusts. While receiving income and losses via a K-1 can offer great tax benefits, two important IRS rules often limit how much loss you can deduct in any given year: the At-Risk Rules and the Passive Activity Loss (PAL) Limitations. These limitations are particularly relevant when dealing with partnership or S-corp investments reported on Schedule K-1.
📄 What Are the At-Risk Rules?
The At-Risk Rules, introduced under IRC Section 465, limit your ability to deduct losses from an activity to the amount of money you have “at risk” in that activity. Essentially, you can only deduct losses up to the amount you stand to lose economically. This includes your cash and adjusted basis in property contributed to the activity, as well as any loans for which you are personally liable.
Amounts that you are not personally liable for, such as nonrecourse loans, generally do not increase your at-risk basis.
Why It Matters for K-1 Investors
If the partnership reports losses on your Schedule K-1, the At-Risk rules may prevent you from deducting the full amount if your at-risk investment is less than the loss allocated to you. The excess loss becomes suspended and carried forward until you increase your at-risk amount or dispose of your interest.
📄 What Are Passive Activity Loss (PAL) Limitations?
The Passive Activity Loss rules, found in IRC Section 469, restrict the deduction of losses from passive activities against non-passive income like wages or business income. Passive activities generally include:
- Rental activities (regardless of your participation, with some exceptions)
- Businesses in which you do not materially participate
If your Schedule K-1 reports losses from passive activities, these losses can only offset passive income. Any unused passive losses are suspended and carried forward to future years or until you sell your interest.
📊 How Do At-Risk and PAL Rules Work Together?
Both rules apply independently, meaning your loss deduction is limited by the more restrictive rule. Here’s the typical order:
- Calculate your at-risk amount—losses cannot exceed this.
- Apply passive activity loss limits—losses in excess of passive income are suspended.
For example, if your Schedule K-1 shows a $50,000 loss:
- Your at-risk amount is $30,000, so you can only deduct $30,000
- Of that $30,000, if you only have $10,000 passive income, you can only deduct $10,000 this year due to PAL rules
- The remaining $40,000 loss ($20,000 at-risk limitation + $20,000 PAL limitation) is suspended and carried forward
🧾 Where Are These Rules Reflected on Your Tax Return?
- At-Risk Limitations: Reported and tracked on Form 6198, At-Risk Limitations.
- Passive Activity Losses: Reported on Form 8582, Passive Activity Loss Limitations, which calculates allowable losses and suspended amounts.
Both forms are critical supplements to your 1040 when you receive losses via Schedule K-1.
📋 Interaction with Schedule K-1
Schedule K-1 provides you with the amounts of income, gain, loss, and deductions allocated to you by the partnership or S-corporation. Key boxes related to losses and basis include:
- Box 1: Ordinary business income or loss
- Box 2 and 3: Rental real estate and other rental income/loss
- Box 13: Other deductions
- Box L: Capital account information—useful for determining basis
To apply At-Risk and PAL rules correctly, you need to know your adjusted basis and your level of participation (material or passive). This information helps determine whether losses are deductible or suspended.
⚠️ Material Participation and Its Impact
Material participation means you are actively involved in the business operations. If you materially participate in the partnership or S-corp activity, losses generally are not passive and therefore not subject to PAL limitations.
The IRS outlines seven tests to determine material participation, including spending more than 500 hours on the activity or being the only participant.
🧠 Practical Tips for Taxpayers Receiving K-1 Losses
- Keep detailed records of your contributions and loans to establish your at-risk amount.
- Track your involvement in the partnership carefully to support material participation claims.
- File Forms 6198 and 8582 with your tax return if you receive losses on your K-1.
- Be aware that suspended losses can be deducted in future years or upon disposition of your interest.
- Consult a tax professional for complex situations or if your K-1 involves multiple activities with different classifications.
✅ Summary Table: At-Risk vs. Passive Activity Limits
| Aspect | At-Risk Rules | Passive Activity Loss Rules |
|---|---|---|
| Purpose | Limit deductions to amount of money personally at risk | Limit deductions to passive income only |
| Applies To | All business losses | Losses from passive activities |
| Effect on Losses | Losses exceeding at-risk amount are suspended | Losses exceeding passive income are suspended |

🔚 Conclusion
The At-Risk and Passive Activity Loss rules are key tax provisions that govern how much loss you can deduct from your investments in partnerships or S corporations reported on Schedule K-1. While these rules can limit deductions in any given year, understanding and tracking your at-risk basis and participation level ensures you maximize your deductions over time and remain compliant with IRS regulations.
Always carefully review your Schedule K-1 and consider consulting with a tax professional to correctly apply these complex limitations and avoid costly mistakes.
