Suspended Losses in a Partnership: Limits and Release Events

Suspended losses in a partnership are loss amounts your K-1 allocated to you that you cannot currently deduct because they failed one of four sequential limits: basis, at-risk, passive activity, and excess business loss. Each limit is a gate. A loss that fails a gate is held back, or “suspended,” and carries forward until the condition that trapped it changes. The gate that traps a loss also determines how you eventually release it, so identifying which limit stopped your deduction is the first thing to do.

The four tests run in a fixed order. Basis first, then at-risk, then the passive activity rules, then the excess business loss cap.¹ A loss stopped at basis never reaches the at-risk test. A loss stopped at at-risk never reaches the passive activity rules. Understanding where your loss is stuck tells you what has to happen for it to come free.

Losses Suspended by Insufficient Basis

Your share of a partnership loss is deductible only up to the adjusted basis of your partnership interest at the end of the tax year.² Allocated $200,000 but your basis is $120,000? You deduct $120,000. The other $80,000 is suspended.

Basis starts with what you contributed. It goes up when the partnership earns income or when your share of partnership debt increases. It goes down when you receive distributions or claim losses. Debt is where partners most often miscount. Recourse debt (where you personally bear the economic risk of loss) adds to the basis of the partner actually on the hook.³ Nonrecourse debt (where the lender can only look to partnership property) gets spread among partners under a multi-step formula that typically tracks each partner’s profit share.⁴

Basis-suspended losses carry forward indefinitely. They become deductible whenever your basis rises again: a new capital contribution, an increased share of partnership debt, or future partnership income flowing through to you.² Released basis losses still have to clear every later gate.

Losses Suspended by the At-Risk Rules

A loss that survives the basis test hits the at-risk limit next. You can deduct only up to the amount you could actually lose if the partnership went under. Your at-risk amount generally includes cash and property you contributed, plus amounts you borrowed for the activity where you are personally liable or have pledged personal assets as collateral.⁵

Here is the trap: nonrecourse debt raises your basis but generally does not raise your at-risk amount, because you have no personal exposure. A partner with $500,000 of basis, of which $400,000 came from nonrecourse financing, has an at-risk amount of only $100,000. Losses over $100,000 clear the basis test and then get stuck at at-risk.

Real estate has an exception. Qualified nonrecourse financing secured by real property counts toward your at-risk amount even though you carry no personal liability.⁵ Without it, most real estate partnership losses would never clear this gate.

Watch for at-risk recapture. If your at-risk amount drops below zero in a later year, often because recourse debt was refinanced into nonrecourse debt, you must recognize income equal to that shortfall. The recaptured amount then becomes a deduction the following year, but the cash-flow hit in the recapture year is real.⁵

At-risk-suspended losses carry forward indefinitely and free up when your at-risk amount recovers, whether through additional capital or a change in the debt structure.

Losses Suspended by the Passive Activity Rules

A loss that clears basis and at-risk faces one more filter. If you don’t materially participate in the partnership’s business, the loss is passive and can only offset income from other passive activities.⁶ No passive income elsewhere on your return? The loss sits and waits.

Material participation turns on seven tests, and you only need to satisfy one for the year.⁷ The most common paths are the 500-hour test, a 100-hour test where no one else participated more than you, and a five-of-ten-years test based on prior material participation. A facts-and-circumstances test exists but excludes management time if anyone else was paid to manage, and it excludes time spent as an investor reviewing financials. Partners who write checks but don’t operate the business rarely clear it. Contemporaneous hour logs matter; reconstruction from memory during an audit is a fight you don’t want.

Publicly Traded Partnerships

Holdings in a publicly traded partnership get their own silo. Losses from a PTP can only offset income from that same PTP, not passive income from other partnerships or rental activities.⁶ The only way to free trapped losses in a PTP is to dispose of your entire interest in that specific partnership.

Losses Suspended by the Excess Business Loss Cap

After the first three tests, one final limit applies. The excess business loss rule caps how much total business loss a noncorporate taxpayer can deduct against nonbusiness income in a year. For 2025, the threshold is $313,000 for single filers and $626,000 for joint filers, with annual inflation adjustments.¹ Amounts over the threshold become a net operating loss carryforward. The One Big Beautiful Bill Act made this limitation permanent, and taxpayers who trigger it file Form 461 with their return.

For a partner in a single partnership, the earlier limits usually do the work before this one is reached. Partners with multiple businesses producing large combined losses are the ones who typically bump into this ceiling.

How Suspended Losses Get Released

A suspended loss doesn’t expire, but the trigger that unlocks it depends on which gate trapped it.

Rebuilding Basis or At-Risk Amount

Basis-suspended and at-risk-suspended losses free up as the underlying number climbs. New capital contributions, an increased debt allocation, or a profitable year that pushes income through to you all raise basis. Recourse debt (or, for real estate, qualified nonrecourse financing) raises at-risk. A freed loss still has to clear every later gate before it actually reaches your return.

Disposing of Your Entire Interest

Selling your full partnership interest in a fully taxable transaction to an unrelated buyer is the strongest release mechanism for passive losses. On complete disposition, all accumulated suspended passive losses from that activity become deductible against any type of income, not just passive income. Two conditions matter. The buyer has to be unrelated; a sale to a family member or related entity leaves the loss suspended in the buyer’s hands until they sell to someone truly unrelated. And it must be your entire interest. Selling a portion doesn’t release anything. For a publicly traded partnership, that means every unit.⁶

Death of a Partner

When a partner dies, suspended passive losses are allowed on the final return only to the extent they exceed the step-up in basis the heir receives.⁶ If the step-up equals or exceeds the accumulated losses, nothing survives to be deducted on the final return.

Gifting the Interest

Gifts are worse. Suspended passive losses attached to a gifted interest are never deductible by you or the recipient. The suspended amount is added to the donee’s basis in the interest instead.⁶ The donee benefits only indirectly, through a smaller gain or larger loss on eventual sale. A gift permanently converts an income-tax deduction into a basis adjustment.

A Note on Self-Employment Tax

Suspended losses do not reduce self-employment tax in the year of suspension. The IRS treats losses disallowed under basis, at-risk, or passive activity rules as not “allowed” for self-employment purposes either. When the loss is eventually released, it can reduce self-employment income in that later year, assuming the activity generates self-employment income at all.

Tracking Suspended Losses and What to File

Your Schedule K-1 shows the full loss allocated to you, not the amount you can actually deduct. Running the limitations and figuring out your deductible number is on you.⁸ Unlike S corporation shareholders, who use Form 7203, partners have no IRS form for outside basis. You keep those records yourself, from the day you acquire the interest through every contribution, distribution, and debt reallocation.

The forms that come into play once specific limits bite:

Form 6198, when you have amounts not at risk in an activity that produced a loss. This calculates and reports the at-risk limitation.⁹
Form 8582, to compute your allowable passive activity loss for the year and track suspended passive losses being carried forward or released.¹⁰
Form 461, when net business losses exceed the excess business loss threshold or when any single category exceeds half that threshold.¹

Because the limits run sequentially, a single year’s loss can end up partly suspended at one level and partly at another. You might deduct $50,000 against basis, watch $30,000 stall at the at-risk level, and see the remaining $20,000 clear at-risk only to be trapped by the passive activity rules. Each piece lives in its own carryforward bucket and follows its own release rules. Keeping those buckets straight across multiple years is the practical reason partnership loss situations tend to warrant professional help.
