At-Risk Rules for Investors

The at-risk rules for investors, codified in Section 465 of the Internal Revenue Code, place a ceiling on how much loss from an investment or business activity an investor can deduct in any given year. The limit is the amount of capital and other resources the investor has genuinely put at economic risk in that activity—a floor that applies independently of the passive-activity loss rules and must be satisfied first.

The core concept: what does “at risk” mean?

The at-risk rules for investors serve a fundamental tax policy purpose: preventing taxpayers from claiming deductions for losses in activities where they have not truly risked their own capital. The “amount at risk” is the economic value an investor has committed to the activity.

An investor is considered to have at-risk capital consisting of:

• Cash and property contributed to the activity at fair market value
• Recourse loans (loans for which the investor is personally liable if the activity fails and cannot repay)
• Retained earnings or previous profits reinvested in the activity

An investor is not considered to have at-risk capital from:

• Nonrecourse loans (loans secured only by the asset financed; the lender’s only remedy is to seize the asset, not to pursue the borrower personally)
• Loans from related parties under certain circumstances
• Loans made on terms not customary for similar activities

The distinction is critical. If an investor borrows $100,000 on a full recourse basis to fund an investment, the investor is at economic risk for the full $100,000—defaulting would mean personal liability. If instead the investor takes a $100,000 nonrecourse mortgage on real estate, the investor is at risk only to the extent of equity in the property; the lender’s claim stops at the real estate itself.

How at-risk limits interact with losses claimed

Each year, the investor calculates the total deductible loss from the activity as the lesser of:

1. The actual economic loss from the activity (revenues minus expenses)
2. The amount at risk in the activity

Any loss in excess of the at-risk amount is disallowed—not immediately deductible—but it carries forward indefinitely. If the activity becomes profitable in future years, the investor may use the prior suspended loss to offset the new income, up to the amount at risk in those later years.

Example: An investor contributes $50,000 cash to a real estate partnership and borrows $100,000 on a recourse basis to purchase a rental property. The at-risk amount is $150,000 (cash plus recourse debt). In year 1, the property generates a $180,000 loss.

The deductible loss is limited to $150,000 (the amount at risk). The remaining $30,000 loss is suspended and carried forward. If the property generates a $40,000 profit in year 2, the investor can deduct $30,000 of the suspended loss and report a net $10,000 gain. The at-risk amount is now $180,000 ($150,000 plus the $30,000 profit retained), so in year 3, if another $50,000 loss arises, it is deductible up to the at-risk amount.

Real property and the nonrecourse debt exception

Real property receives special treatment under Section 465(c)(3). For real estate activities, an investor’s at-risk amount is increased by qualified nonrecourse real estate debt—nonrecourse loans taken out to purchase or improve the property, provided the loan is from a third party (not the seller or a related party) on commercially reasonable terms.

This exception is substantial. A real estate investor who purchases a $500,000 apartment building with a $400,000 nonrecourse mortgage and $100,000 down payment has an at-risk amount of $500,000 (not just $100,000), because the mortgage qualifies as real property nonrecourse debt.

This exception reflects the reality that real estate investments are asset-based; the nonrecourse lender’s interest is aligned with the property’s value. The exception does not apply to nonrecourse debt on other assets (equipment, inventory, intangible property), nor to loans from related parties or on non-arm’s-length terms.

Carryforward of excess losses

One of the most important features of at-risk rules is that disallowed losses do not disappear; they are suspended and carried forward. Unlike some other loss limitations that may expire or be permanently forfeited, suspended at-risk losses can offset income in any future year in which the investor has additional at-risk capital in that activity.

This carryforward can be valuable in long-term business or real estate ventures. An investor may deliberately operate at a loss for several years while building at-risk equity, then offset future profits with accumulated suspended losses.

Interaction with passive-activity loss rules

The at-risk rules apply independently of and before passive-activity loss limitations (Section 469). This means:

1. First, a loss is tested against the at-risk limitation. If the loss exceeds the amount at risk, the excess is suspended.
2. Next, any loss that passes the at-risk test is tested against passive-loss rules. A passive loss may be suspended even if it is fully at-risk.

In practice, an investor may face both limitations. A passive activity loss of $100,000 in a business in which the investor has only $70,000 at risk is limited to $70,000 by at-risk rules. The $70,000 deductible loss is then subject to passive-loss limitations and may be further limited or suspended depending on the investor’s income type and passive activity history.

Activities subject to at-risk rules

The at-risk rules apply to substantially all business and investment activities, including:

• Real estate rental activities
• Equipment leasing
• Oil and gas ventures
• Farming
• Commodity trading
• Partnership and S-corporation interests
• Sole proprietorships

Limited exceptions exist for closely held C-corporations and certain real estate investments, but these are narrow.

Planning considerations

Investors in risky ventures often structure investments to maximize at-risk basis. Contributing cash, taking recourse debt, and reinvesting profits all build at-risk capital and allow larger losses to be deducted.

Conversely, an investor with suspended at-risk losses should monitor whether additional capital contributions or debt repayment could increase the at-risk amount and unlock deductions in the current year.

In partnerships and S-corporations, the at-risk limitation interacts with basis calculations and the rules for adjusting basis for contributions, withdrawals, and losses. An investor’s basis (which determines when losses can be deducted) is capped by the at-risk amount, creating a double constraint.
