At-Risk Rules Overview

The at-risk rules under §465 limit a taxpayer's deductible losses from an activity to the amount the taxpayer has at risk in that activity. The rules were enacted in 1976 to prevent taxpayers from deducting losses in excess of their economic investment in tax shelter activities. The at-risk rules apply to most activities, including partnerships, S-Corps, and sole proprietorships, but not to C-Corps (other than closely held C-Corps).

The at-risk amount is generally the taxpayer's cash investment plus the adjusted basis of property contributed plus amounts borrowed for use in the activity for which the taxpayer is personally liable. The at-risk amount is reduced by losses deducted in prior years and increased by income from the activity. If the at-risk amount goes negative (because the taxpayer has received distributions in excess of their investment), previously deducted losses must be recaptured as income.

What Is Included in the At-Risk Amount

The at-risk amount includes: (1) cash and the adjusted basis of property contributed to the activity; (2) amounts borrowed for use in the activity for which the taxpayer is personally liable or has pledged property (other than property used in the activity) as security; and (3) the taxpayer's share of qualified nonrecourse financing (real estate only).

ItemIncluded in At-Risk Amount?
Cash investmentYes
Adjusted basis of contributed propertyYes
Recourse debt (personally liable)Yes
Nonrecourse debt (not personally liable)No (except QNF for real estate)
Qualified nonrecourse financing (real estate)Yes
Guarantees by related partiesNo
Stop-loss agreementsNo

Qualified Nonrecourse Financing (Real Estate Exception)

The most important exception to the at-risk rules is qualified nonrecourse financing (QNF) for real estate activities. Under §465(b)(6), a taxpayer's share of nonrecourse financing secured by real property used in the activity is included in the at-risk amount if: (1) the financing is from a qualified lender (a bank, savings institution, or other commercial lender); (2) the financing is not convertible debt; and (3) no person is personally liable for repayment.

The QNF exception is critical for real estate investors who finance properties with nonrecourse mortgages. Without the exception, a real estate investor who purchases a $1,000,000 property with $200,000 down and an $800,000 nonrecourse mortgage would have an at-risk amount of only $200,000 — limiting deductible losses to $200,000. With the QNF exception, the at-risk amount is $1,000,000 (the full purchase price), allowing the investor to deduct losses up to $1,000,000.

Interaction with Passive Activity Loss Rules

The at-risk rules and the passive activity loss (PAL) rules under §469 are two separate limitations on loss deductions. A taxpayer must clear both limitations to deduct a loss. The at-risk rules are applied first: if the loss exceeds the at-risk amount, the excess is suspended. The remaining loss (up to the at-risk amount) is then tested against the PAL rules: if the activity is passive, the loss is suspended until the taxpayer has passive income or disposes of the activity.

Practitioners must track both the at-risk amount and the PAL basis for each client activity. The at-risk amount and the PAL basis are not the same: the at-risk amount includes QNF for real estate, while the PAL basis does not. A real estate investor with a $1,000,000 at-risk amount may still have losses suspended under the PAL rules if the investor does not materially participate in the activity.

Frequently Asked Questions

The at-risk amount is generally the taxpayer's cash investment plus the adjusted basis of property contributed plus amounts borrowed for which the taxpayer is personally liable. For real estate, qualified nonrecourse financing (QNF) is also included. The at-risk amount is reduced by losses deducted in prior years and increased by income from the activity.

Qualified nonrecourse financing (QNF) is nonrecourse debt secured by real property used in the activity, borrowed from a qualified lender (bank, savings institution, or other commercial lender), and not convertible debt. QNF is included in the at-risk amount for real estate activities, allowing investors to deduct losses up to the full value of the financed property.

The at-risk rules are applied first: if the loss exceeds the at-risk amount, the excess is suspended. The remaining loss (up to the at-risk amount) is then tested against the PAL rules. A taxpayer must clear both limitations to deduct a loss. Practitioners must track both the at-risk amount and the PAL basis for each client activity.

If the at-risk amount goes negative (because the taxpayer has received distributions in excess of their investment), previously deducted losses must be recaptured as income in the year the at-risk amount goes negative. The recapture amount is the lesser of: (1) the amount by which the at-risk amount is negative, or (2) the total losses deducted in prior years from the activity.

Yes — the at-risk rules apply to S-Corp shareholders. An S-Corp shareholder's at-risk amount includes: (1) the shareholder's basis in S-Corp stock; (2) the shareholder's basis in loans made to the S-Corp; and (3) the shareholder's share of recourse debt for which the shareholder is personally liable. The at-risk rules are applied at the shareholder level, not the S-Corp level.

More Tax Planning FAQs

What is the IRS audit risk for this strategy?
The IRS audit rate for individual returns is approximately 0.4% overall, but increases significantly for returns with Schedule C income, large deductions, or specific strategies. Proper documentation is the best defense against an audit. Keep contemporaneous records, maintain written agreements, and ensure all deductions are supported by receipts and business purpose documentation.
How does this strategy interact with the alternative minimum tax (AMT)?
Many tax strategies that reduce regular income tax can trigger or increase AMT liability. Common AMT triggers include: ISO exercises, large state tax deductions, accelerated depreciation, and passive activity losses. Taxpayers should model both regular tax and AMT before implementing aggressive tax strategies to ensure the net benefit is positive.
What is the statute of limitations for IRS assessment of this strategy?
The IRS generally has three years from the later of the return due date or filing date to assess additional tax. If the taxpayer omits more than 25% of gross income, the statute is extended to six years. There is no statute of limitations for fraudulent returns or failure to file. Taxpayers should retain tax records for at least seven years to cover the extended statute of limitations.
How should this strategy be documented to withstand IRS scrutiny?
Documentation is the cornerstone of any tax strategy. Maintain contemporaneous records (created at the time of the transaction), written agreements, business purpose statements, and receipts. For strategies involving related parties, ensure all transactions are at arm’s length and documented with fair market value support. The burden of proof is on the taxpayer to substantiate deductions.
What is the economic substance doctrine and how does it apply?
The economic substance doctrine (§7701(o)) requires that transactions have both objective economic substance (a reasonable possibility of profit) and subjective business purpose (a non-tax reason for the transaction). Transactions that lack economic substance are disregarded for tax purposes, and the 40% strict liability penalty applies. Legitimate tax planning strategies must have genuine business purposes beyond tax reduction.
How does this strategy affect state income taxes?
Federal tax strategies do not always produce the same results at the state level. Some states do not conform to federal tax law changes (e.g., bonus depreciation, QSBS exclusion). Taxpayers should model the state tax impact of any federal tax strategy, especially in high-tax states like California, New York, and New Jersey. Some strategies may save federal taxes while increasing state taxes.
What is the step-transaction doctrine and how does it apply?
The step-transaction doctrine allows the IRS to collapse a series of related transactions into a single transaction if the intermediate steps have no independent significance. This doctrine is used to prevent taxpayers from using artificial multi-step transactions to achieve tax results that would not be available in a single transaction. Legitimate tax planning strategies should have independent business purposes for each step.
How does this strategy interact with the passive activity loss rules?
Passive activity losses (§469) can only offset passive income. Active business income, wages, and portfolio income are not passive. Real estate rental income is generally passive unless the taxpayer qualifies as a Real Estate Professional. Passive losses that cannot be used currently are suspended and carried forward to offset future passive income or recognized when the passive activity is disposed of in a fully taxable transaction.
