At-Risk Rules for Investors

The at-risk rules cap the amount of deductible losses from an investment or business activity to the economic capital the taxpayer has genuinely put at risk. A taxpayer cannot claim losses exceeding the real money invested, even if a partnership agreement or business combination purports to allocate larger losses.

The economic principle

The at-risk rules rest on a simple premise: you can only claim a loss deduction on something you have truly risked. If you invest $50,000 of your own money in a business venture, you have risked $50,000. If that venture loses $50,000 or more, you can deduct the loss. But if the venture loses $100,000 and you have only put $50,000 at personal risk—perhaps because a lender (not a partner) covers the other $50,000—you can only deduct $50,000 of losses, no more.

This rule prevents the tax shelter abuse that was rampant before Section 465 was enacted. Without the at-risk rules, sophisticated investors could structure deals where they poured very little personal capital yet claimed disproportionately large deductions based on borrowed money, wiping out income on paper while risking almost nothing economically.

What counts as “at risk”

Your at-risk amount includes:

• Cash invested directly into the activity
• Net fair market value of property you have contributed (land, equipment, inventory)
• Recourse debt for which you are personally liable if the venture fails
• Guaranteed payments or other amounts you are obligated to contribute in the future (if unconditional)

What does not count as at risk:

• Nonrecourse debt (loans secured only by the activity’s assets; creditors cannot pursue your personal assets if the venture defaults)
• Amounts financed by a related party in a tax-avoidance arrangement
• Pledges or contingent guarantees that are not yet binding
• Borrowed funds supplied by the partnership or the activity itself (circular borrowing does not increase your risk)

The partnership example

Suppose a partnership allocates a $100,000 loss to you, but you invested only $30,000 in cash and the partnership borrowed $50,000 on a nonrecourse basis (typical real estate syndication) with no personal guarantee. Your at-risk amount is $30,000. You can deduct only $30,000 of the allocated loss; the remaining $70,000 is suspended and carried forward.

In later years, if the partnership generates taxable income and allocates it to you, or if you invest additional capital, your at-risk basis grows, and suspended losses are released dollar-for-dollar.

At-risk basis vs. adjusted basis

At-risk basis is separate from your tax basis in the investment (which is tracked for capital gains calculations and distributions). You might have a tax basis of $150,000 in a partnership interest but an at-risk amount of only $50,000. Your loss deduction is limited by the at-risk amount, not the tax basis, even though the tax basis might be higher.

This distinction matters for cost basis tracking and for understanding why loss limitations sometimes prevent large deductions despite apparent basis availability.

Carryforward of suspended losses

When a loss exceeds your at-risk amount, the excess does not disappear. It is suspended and carried forward indefinitely. If you later contribute additional capital to the venture, your at-risk amount increases, and the oldest suspended losses are released first. You cannot accelerate the release of suspended losses by selling your interest; instead, suspended losses are generally forfeited if you dispose of the activity entirely (though some exceptions exist for like-kind exchanges in certain contexts).

Interaction with passive loss rules

The passive loss rules provide an additional limitation on top of the at-risk rules. A loss might survive the at-risk test but fail the passive loss test (which prohibits deducting passive losses against active income or capital gains, except up to $25,000 for real estate professionals).

Typically, the at-risk rules bite first (a narrower, often stricter limitation), and passive losses are evaluated on what survives the at-risk test. Some losses are limited by both rules in sequence.

Activities covered

The at-risk rules apply to most business and investment activities, but certain real estate ventures have special rules. Pre-1987 real estate investments are often grandfathered from strict at-risk limitations, while post-1986 real estate is subject to the full at-risk regime. Oil and gas activities, farming operations, equipment leasing, and equipment financing also carry industry-specific at-risk nuances that go beyond the general framework.

Remedying an at-risk violation

If a taxpayer claimed more loss deduction than their at-risk amount permitted, the IRS can disallow the excess deduction and assert penalties. The remedy is to amend the return, recalculate the loss limitation correctly, and potentially claim the suspended loss in a later year when at-risk basis expands. Professional advisors often work backward from partnership K-1 allocations to ensure that clients understand their true at-risk position before claiming the full allocated loss.
