At-Risk Rules Under Section 465: Why Basis Alone Does Not Make a Loss Deductible
A Los Angeles business owner has enough basis to absorb a $200,000 partnership loss and claims it. The IRS disallows most of it anyway. Basis was never the only test — the at-risk rules under IRC Section 465 apply after basis and before the passive activity rules, and money borrowed on a nonrecourse basis generally does not count. Pathfinding Consultants provides business tax preparation Los Angeles business owners rely on to work the loss limitation sequence in the right order.

What the At-risk Rules Limit
The at risk rules under IRC Section 465 limit the amount of loss a taxpayer may deduct from a business or income-producing activity to the amount the taxpayer actually has at risk in that activity. The rules apply to individuals, estates, trusts, and closely held C corporations — a corporation qualifies as closely held for this purpose when five or fewer individuals own more than 50% of the stock, applying the attribution rules of Section 542(a) (source: IRC Section 465; IRS Instructions for Form 6198). Widely held C corporations are generally exempt.
The at risk rules are not limited to tax shelters. The Form 6198 instructions list the original targeted categories — film and videotape production, farming, leasing of depreciable personal property, oil and gas exploration, and geothermal deposits — and then add a catch-all sixth category sweeping in every other trade or business activity and every activity engaged in for the production of income. In practice, that reaches most Los Angeles operating businesses and rental activities.
What Counts Toward the Amount at Risk
The amount at risk generally includes cash contributed to the activity, the adjusted basis of property contributed, recourse debt for which the taxpayer is personally liable, and qualified nonrecourse financing under Section 465(b)(6) (source: IRS Instructions for Form 6198). Everything turns on whether the taxpayer bears genuine economic risk of loss.
Section 465 is explicit about what does not count. A taxpayer is not considered at risk with respect to amounts protected against loss through nonrecourse financing, guarantees, stop-loss agreements, or other similar arrangements — with casualty insurance and insurance against tort liability specifically excluded from that disqualification. Nonrecourse loans used to finance the activity, to acquire property used in it, or to acquire the interest itself are also outside the amount at risk, unless the loan is secured by the taxpayer's own property that is not used in the activity.
Qualified Nonrecourse Financing for Real Estate
The most important exception for Los Angeles real estate operations is qualified nonrecourse financing. Under Section 465(b)(6), a taxpayer may be treated as at risk for financing that meets four tests: no person is personally liable for repayment; the borrowing is in connection with the activity of holding real property; it is secured by real property used in the activity; and it is not convertible debt (source: IRC Section 465(b)(6); IRS Instructions for Form 6198). The lender must be a qualified person — generally someone regularly engaged in the business of lending, such as a bank — or a federal, state, or local government or instrumentality, or the loan must be government guaranteed.
Qualified nonrecourse financing is why an apartment or commercial property partnership can generate deductible losses despite carrying substantial nonrecourse mortgage debt. Under the Treasury regulations, incidental personal property is disregarded in the collateral analysis, and non-real-property collateral is ignored where its fair market value is less than 10% of total collateral value. For a partnership, a partner's share of qualified nonrecourse financing is determined by the partner's share of the liabilities incurred in connection with that financing, within the meaning of Section 752, and appears on the Schedule K-1 as qualified nonrecourse financing.

The Order of the Loss Limitation Rules
Sequence determines the answer. The loss limitation rules apply in a fixed order: basis first, then the at risk rules on Form 6198, then the passive activity rules on Form 8582, and finally the excess business loss limitation (source: IRS Instructions for Form 6198). A loss does not reach Form 8582 until Form 6198 has said it is allowed.
Getting the loss limitation rules out of order produces a wrong answer even when every individual calculation is correct. A taxpayer who applies the passive activity rules first and concludes a loss is deductible because passive income exists has skipped the step that may have disallowed the loss entirely. Each layer is a separate gate, and a loss must clear all of them.
Form 6198 and the Carryforward
Form 6198 reporting is required for each activity where any amount is not at risk and a loss may be limited — a separate form per activity, not one form covering the business as a whole. The IRS describes Form 6198 as the mechanism to figure the profit or loss from an at-risk activity for the current year, the amount at risk for the current year, and the deductible loss for the current year.
The deductible loss is the smaller of the current-year activity loss or the amount at risk, and the disallowed remainder carries forward indefinitely against the same activity. Under Section 465(b)(5), the amount at risk in subsequent years is reduced by the portion of the loss allowed as a deduction (source: IRC Section 465(b)(5)), which means the at-risk figure is not static — it moves every year with contributions, distributions, allowed losses, and changes in financing. Form 6198 reporting is a planning tool as much as a return attachment, because a mid-year review leaves time to restructure financing before the year closes.
Why the File Matters More Than the Form
Business consulting near me searches from Los Angeles business owners spike when a loss year arrives and the at-risk history — contributions, personal liability, pledged outside property, distributions, prior allowed losses — has never been tracked. Pathfinding Consultants is an Enrolled Agent firm providing business tax preparation Los Angeles business owners have relied on to maintain a running at-risk file per activity so the conclusion is traceable without asking a client to reconstruct financing terms years later.
Owners tracking basis alongside at-risk should also see our guide to Form 7203 and S corporation shareholder basis, and our bookkeeping services overview covers the contribution and distribution records the calculation depends on. A business consulting near me conversation in May, when a loss is anticipated rather than already reported, is when financing can still be reviewed.
Common Mistakes with the At-risk Rules
Including nonrecourse debt in the amount at risk when it does not meet the qualified nonrecourse financing tests
Applying the passive activity rules before the at risk rules, when the loss limitation rules run basis, then at-risk, then passive
Overlooking that amounts protected by a guarantee or stop-loss agreement are not at risk, even where the taxpayer signed for the debt
Failing to file Form 6198 for each separate activity where an amount is not at risk and a loss may be limited
Treating the amount at risk as static, when it is reduced each year by losses allowed and by distributions taken
Every one of these mistakes is avoidable when the amount at risk is tracked per activity each year and the loss limitation rules are applied in their statutory order rather than in whatever sequence the software defaults to. A business consulting near me search early in a loss year is when business tax preparation Los Angeles support can still review financing terms, and Form 6198 reporting prepared alongside that review is far more defensible than one assembled at filing.
Get your at-risk position reviewed before the loss year closes.
