A Schedule K-1 can report a loss while the partner’s individual return allows little or none of it. That does not necessarily mean the K-1 is wrong. Several owner-level limitation systems can apply in sequence.
Outside basis comes first
A partner generally needs sufficient adjusted tax basis in the partnership interest to deduct an allocated loss. Basis may start with contributions and purchase price, then change for income, loss, distributions, and the partner’s share of certain partnership liabilities.
Book capital shown on the K-1 is not a substitute for a complete outside-basis calculation.
Four limitations may apply
The rules are generally considered in order. Passing one limitation does not guarantee a current deduction under the next.
- Tax-basis limitation under Section 704(d)
- At-risk limitation under Section 465
- Passive-activity limitation under Section 469
- Excess-business-loss limitation under Section 461(l)
What happens to a suspended loss
A loss limited by basis is generally carried forward until additional basis is created. Passive losses may become available when the activity generates passive income or when the taxpayer disposes of the entire interest in a qualifying taxable transaction.
The reason for suspension matters because each category has different release rules and tracking requirements.
Planning before a transaction
Contributions, debt changes, refinancings, distributions, ownership transfers, and entity restructurings can affect basis. Review the impact before year-end and before cash or property moves between the partner and partnership.
