The principle
Section 465 limits your deduction from an activity to the amount you have at risk in it. The policy is simple: you should not be able to deduct an economic loss you cannot actually suffer.
The application is not simple at all, because what counts as at risk depends on the precise financing and guarantee arrangements in the documents, and those differ between investors in the same deal.
What counts
| Generally at risk | Generally not at risk |
|---|---|
| Cash you contributed | Amounts protected against loss by a guarantee, stop-loss, or similar arrangement |
| Adjusted basis of property you contributed | Borrowing from a person with an interest in the activity, other than as a creditor |
| Amounts borrowed for which you are personally liable | Nonrecourse debt, outside the real property exception |
| Amounts borrowed where you pledged property not used in the activity | Property pledged that is itself used in the activity |
There is a significant exception for real property activities, where qualified nonrecourse financing can count toward the at-risk amount even though the borrower is not personally liable. It is specific, it has conditions, and it does not extend to activities generally.
Why identical checks diverge
This is where the rule becomes practical rather than theoretical.
Consider a structure funded partly by contributed capital and partly by borrowing. One investor signs a personal guarantee on their share of the debt. Another does not. The first is at risk for the guaranteed amount; the second generally is not.
Same deal, same capital, same headline deduction in the materials. Materially different deductible amounts, decided entirely by a signature page. It is common for investors not to know which side of that line they are on.
Where it sits in the order
At-risk is not the only gate and the order matters.
- 01Basis. You cannot deduct beyond your basis in the interest.
- 02At risk. Section 465 then limits you to what you genuinely have at stake.
- 03Passive activity. Section 469 determines whether what survives can offset active income at all.
- 04Excess business loss. Section 461(l) caps what reaches non-business income in the year, with the excess becoming a carryforward.
A number quoted without reference to all four is a gross figure. Each gate can only reduce it, and the distance between the headline and what reaches your return is frequently the whole of the decision.
Where this lands
- 01Read the guarantee provisions before funding, not after. They are where your at-risk amount is actually determined.
- 02Establish whether any part of your investment is protected against loss. Protection is commercially attractive and it reduces what you are at risk for.
- 03Track the amount annually. It moves with distributions, additional contributions, and changes in debt.
- 04Have your own CPA confirm the figure for your facts. This is not a question that generalises across investors in the same deal.
