Quick Answer
Suspended passive activity losses are partly deductible at death, but not fully. For tax year 2025, only the amount of suspended passive losses that exceeds the step-up in basis (under IRC §1014) is deductible on the decedent’s final Form 1040. Losses equal to the step-up are permanently lost.
When someone dies holding a rental property, a partnership interest, or S corporation stock with unused passive losses, those losses do not simply pass to the heirs or the estate. Federal law under IRC §469(g)(2) releases only the portion of the losses that the date-of-death basis step-up does not already cover, and the rest disappears forever.
This matters because the timing is unforgiving. The deduction happens once, on the final individual income tax return, and there is no carryover, no transfer, and no second chance after that return is filed. Surviving spouses, executors, and heirs who miss it lose real money — often tens of thousands of dollars.
According to IRS Statistics of Income data, millions of individual returns each year report rental, partnership, and S corporation activity on Schedule E, the most common source of suspended passive losses.

Passive Losses 101: The Words Behind the Rule
A passive activity is a business or rental investment in which you do not “materially participate.” Material participation means you are regularly, continuously, and substantially involved in running the activity, as defined in the passive activity loss rules. If you are mostly a money-behind-the-scenes investor, the activity is passive.
A passive activity loss (PAL) is an ordinary loss from that investment — for example, a rental house that loses money after depreciation, or a limited partnership interest that throws off a yearly loss. Real estate and pass-through investments such as hedge funds, private equity funds, partnerships, and S corporations are the usual sources.
Here is the catch that traps the loss. Under the passive loss rules, you cannot use a passive loss to offset your wages, your interest, or your dividends. You can only use a passive loss against passive income. If you have no passive income, the loss is suspended — frozen and carried forward year after year on Form 8582 until one of two things happens.
The two release events are simple. First, you eventually earn passive income that the loss can offset. Second, you make a fully taxable disposition of the entire activity to an unrelated party, which frees every suspended loss tied to that activity at once. Death is treated as a kind of disposition — but a special, limited one, which is the whole point of this article.
A suspended passive loss carryover, then, is just the stack of unused passive losses that have piled up and rolled forward. When the owner dies still holding those losses, IRC §469(g)(2) decides their fate. The consequence of misunderstanding this rule is a permanent, unrecoverable loss of a deduction, so it pays to get it exactly right.
The Core Rule at Death: IRC §469(g)(2)
When a taxpayer dies holding a passive activity with suspended losses, IRC §469(g)(2) controls. It does not release all the losses to the final return, and it does not let them flow to the estate or the heirs. Instead, it allows only a slice.
The plain-English rule is this: the suspended losses are deductible on the decedent’s final Form 1040 only to the extent the losses exceed the step-up in basis the property receives at death. Any losses equal to or below the step-up are “shall not be allowed as a deduction for any taxable year” — meaning gone for good.
The formula the IRS applies is short:
Deductible loss on final return = Total suspended PALs − Date-of-death basis step-up
The step-up in basis comes from IRC §1014. When you die, most assets in your estate get their tax basis reset to fair market value on the date of death. The step-up is the increase: fair market value minus the old adjusted basis. The step-up in basis is normally a gift to heirs because it wipes out built-in gain — but for passive losses it works against you.
Why the Step-Up Eats Your Loss
The logic, while painful, is consistent. A suspended passive loss exists to offset future gain when you sell the activity. But the §1014 step-up already eliminates that built-in gain by resetting basis to fair market value. Congress decided you cannot have both the step-up and the full loss deduction, because that would be a double tax benefit.
So the step-up “absorbs” the losses dollar-for-dollar. If the step-up is large, it can swallow the entire suspended loss and leave nothing to deduct. If the step-up is small, more of the loss survives and lands on the final return. This is the single most important mechanic to understand, and it is the opposite of what most families expect.
Where the Deduction Lands
The freed-up portion is reported on the decedent’s final Form 1040, the income tax return covering the part of the year up to the date of death. It is an ordinary loss, so it can offset any income on that final return — wages, interest, dividends, retirement distributions, or capital gains. This is the one moment passive losses break free of the passive-only handcuffs.
The final Form 1040 is generally due on the normal filing deadline of the year after death — for a 2025 death, that is April 15, 2026 (with the usual extension option). IRS Publication 559 is the controlling guide for survivors, executors, and the final return. Miss the deduction on this return and you must amend within the refund statute of limitations or lose it.
A Fully Worked Example (Copy the Math)
Walk through the numbers slowly, because the dollars are where families gain or lose.
Assume a taxpayer dies in 2025 owning a passive rental investment. At the date of death it has:
- Adjusted basis (old basis): $50,000
- Fair market value: $75,000
- Suspended passive losses: $30,000
Step one: find the step-up. Fair market value of $75,000 minus old basis of $50,000 equals a $25,000 step-up under §1014.
Step two: apply the formula. Total suspended losses of $30,000 minus the $25,000 step-up equals $5,000 deductible on the final Form 1040.
Step three: identify what is lost. The remaining $25,000 of suspended losses — the part equal to the step-up — is permanently disallowed. It cannot be used by the decedent, the estate, or the heirs in any year.
So the family deducts $5,000 as an ordinary loss against any income on the final return, and watches $25,000 vanish. If that taxpayer had instead sold the property the day before death in a fully taxable sale to an unrelated buyer, all $30,000 would have been released. Timing changes everything.
Which Situation Applies to You?
The answer shifts based on how the property was held and who died. Find your situation below and read the matching section.
- You inherited or are settling an estate with a rental, partnership, or S corp interest → read “The Core Rule” and the worked example above; the step-up reduces the deductible loss.
- You are a surviving spouse who filed jointly → read “Surviving Spouses and Joint Returns” below; whose losses they are matters.
- The asset sat in a revocable living trust or other grantor trust → read “The Grantor Trust Exception” below; you may free 100% of the losses.
- The estate kept the property for a while before distributing it → read “Estate Administration and Termination” below; new losses follow different rules.
- You are planning ahead while still alive → read “Planning Moves” below; a lifetime sale or gift may beat death.
Surviving Spouses and Joint Returns
When a married couple files jointly, passive losses are tracked by which spouse owns the activity. At the first spouse’s death, §469(g)(2) applies only to the decedent’s passive activities and the losses attributable to them. The surviving spouse’s own passive losses keep rolling forward on the surviving spouse’s future returns.
This split matters in community property states and joint-ownership situations. In a community property state, a jointly owned activity may be treated as half each, so only the decedent’s half of the suspended loss runs through the death rule, and only the decedent’s half of the property gets a date-of-death step-up. The surviving spouse’s half generally keeps its old basis and its share of the losses.
The consequence of getting the split wrong is real money. If a preparer dumps all the couple’s suspended losses through §469(g)(2), the surviving spouse can lose carryovers that were rightfully theirs to keep. The fix is to allocate the losses by owner before filing the final joint return, and to document the allocation.
The Grantor Trust Exception (Free 100% of the Losses)
There is a powerful exception when an asset is held in a grantor trust — most often a revocable living trust — whose assets are not included in the decedent’s gross estate. For income tax purposes, a grantor trust and the individual are the same taxpayer, so §469(g)(2) applies the same way.
Here is the twist. If the trust assets are not pulled into the gross estate, they generally get no §1014 step-up in basis. With no step-up, there is nothing to absorb the losses — so the formula releases 100% of the suspended passive losses onto the final Form 1040. The NYSSCPA analysis of this rule walks through exactly this outcome.
The IRS reached this conclusion in Field Service Advice 200106018, involving a qualified Subchapter S trust whose income-tax owner died with suspended losses. Because the trust assets were not in the gross estate, there was no step-up, and the suspended losses were allowed on the final return to the extent they exceeded the (zero) step-up — effectively all of them.
Be careful, though: this is a niche, technical position, and most revocable living trusts are included in the gross estate and do get a step-up. The grantor-trust full-release outcome applies only to the rarer case where the assets are intentionally kept out of the estate. The next step here is to have a tax attorney confirm gross-estate inclusion before relying on a full release.
Estate Administration and Termination
If the estate holds the passive activity after death instead of selling it, two more rules kick in. They govern losses that arise after the date of death.
First, during estate administration, the estate takes the property with its stepped-up basis and then generates its own suspended losses going forward, based on whether the executor materially participates. In practice, executors rarely meet the material participation tests, so the activity stays passive and new losses suspend at the estate level until the estate sells the activity or terminates.
Second, when the estate terminates and distributes the activity to a beneficiary, IRC §469(j)(12) applies. The estate’s own suspended losses tied to that interest are added to the beneficiary’s basis rather than deducted by the estate or passed out to the heir. The beneficiary’s later material participation does not change this; it only affects future losses.
Scenario Tables: The Three Most Common Cases
The first table covers the everyday case of a property included in the estate with a step-up.
| Holding and Step-Up Situation | What Happens to the Suspended Losses |
|---|---|
| Property in gross estate, step-up smaller than losses | The excess of losses over the step-up is deductible on the final Form 1040; the rest is lost. |
| Property in gross estate, step-up equal to or larger than losses | None of the suspended losses are deductible; all are permanently disallowed. |
| Grantor trust assets not in gross estate, no step-up | 100% of the suspended losses are deductible on the final Form 1040. |
The second table compares death against a lifetime disposition of the same activity.
| Event Triggering the Losses | Tax Result for the Suspended Losses |
|---|---|
| Fully taxable sale to an unrelated party while alive | All suspended losses are fully released against any income. |
| Death holding the activity with a basis step-up | Only the losses exceeding the step-up are deductible; the rest die. |
| Gift of the passive activity while alive | No losses deducted; suspended losses are added to the donee’s basis. |
The third table shows where the losses go across the three stages after death.
| Stage in the Process | Treatment of Passive Losses |
|---|---|
| Decedent’s date of death | Pre-death suspended losses run through §469(g)(2) on the final Form 1040. |
| Estate administration period | New losses suspend at the estate level; usually passive because executors rarely materially participate. |
| Estate terminates, interest distributed | Estate’s suspended losses are added to the beneficiary’s basis under §469(j)(12). |
Three Named Examples
Example 1 — Maria’s Rental Duplex
Maria dies in 2025 owning a rental duplex with a $200,000 adjusted basis, a $260,000 fair market value, and $45,000 of suspended passive losses. The step-up is $60,000 ($260,000 − $200,000). Because the $60,000 step-up is larger than the $45,000 of losses, the formula leaves nothing: all $45,000 is permanently lost, and Maria’s heirs get a stepped-up duplex but zero loss deduction.
Example 2 — David’s S Corporation Stock
David dies in 2025 holding S corporation stock with $50,000 of suspended passive losses. At death, the stock’s basis steps up by $30,000. Applying the formula, $50,000 − $30,000 leaves $20,000 deductible on David’s final Form 1040 as an ordinary loss against his other income, while the remaining $30,000 is lost. This mirrors the Tom Talks Taxes worked example of an S corporation shareholder’s death.
Example 3 — Grace’s Revocable Trust Kept Out of the Estate
Grace, the income-tax owner of a grantor trust, dies in 2025 with $40,000 of suspended losses on a partnership interest held in that trust. Because the trust assets are not included in her gross estate, there is no step-up — so the entire $40,000 is freed and deductible on her final Form 1040. The trade-off is that her heirs inherit the partnership interest with the old, lower basis.
Mistakes to Avoid
- Assuming the heirs inherit the losses. Suspended passive losses do not transfer to beneficiaries; missing this means claiming a deduction that does not exist and inviting an IRS adjustment.
- Deducting the full suspended loss on the final return. Only the amount over the step-up is allowed; overstating it can trigger penalties and interest on the deficiency.
- Forgetting the step-up reduces the deduction. Treating the step-up as purely good news causes families to expect a loss they will not get.
- Filing all joint losses through the death rule. Running the surviving spouse’s own carryovers through §469(g)(2) wrongly destroys losses the survivor was entitled to keep.
- Ignoring the grantor-trust angle. Failing to check whether assets were outside the gross estate can forfeit a 100% loss release worth tens of thousands.
- Missing the final-return deadline. Skipping the deduction on the final Form 1040 means amending within the statute or losing it; the final 2025 return is generally due April 15, 2026.
- Confusing passive losses with capital loss carryovers. Different rules apply; per Rev. Rul. 74-175, capital loss carryovers also die with the taxpayer, but the mechanics differ.
How Passive Losses Compare to Other Carryovers at Death
Passive losses are not the only tax attribute affected by death. Here is how the common carryovers compare.
| Carryover Type | What Happens at the Owner’s Death |
|---|---|
| Passive activity losses | Deductible on the final Form 1040 only to the extent they exceed the §1014 step-up; the rest is lost. |
| Capital loss carryovers | Used on the final return (subject to the annual limit); any unused amount expires and cannot pass to the estate. |
| Net operating losses (NOLs) | Deductible on the final return; any remaining NOL expires and does not carry to the estate or heirs. |
| Charitable contribution carryovers | Generally lost at death; they do not transfer to the estate or beneficiaries. |
Do’s and Don’ts
Do’s:
- Do calculate the step-up first, because the deductible loss is whatever the losses exceed the step-up by.
- Do gather the date-of-death fair market value with an appraisal, since the step-up depends on it.
- Do allocate joint losses by owner so the surviving spouse keeps their own carryovers.
- Do check whether assets were inside or outside the gross estate, because that decides if 100% of the losses release.
- Do consider a fully taxable sale before death when health and timing allow, to free every suspended loss.
Don’ts:
- Don’t sell to a related party to trigger losses, because related-party sales do not release suspended PALs.
- Don’t assume your state follows the federal result, since conformity varies and a few states compute passive losses differently.
- Don’t overlook Form 8582, where the suspended losses are tracked and where the final-year computation begins.
- Don’t deduct losses already absorbed by the step-up, because that portion is disallowed by law.
- Don’t wait past the final return deadline, because the deduction is hard to recover once the statute runs.
Pros and Cons of the Death Rule
Pros:
- Some losses survive, because the excess over the step-up is fully deductible against any income on the final return.
- The freed loss is ordinary, so it can offset wages, interest, and dividends, not just passive income.
- The step-up still benefits heirs by erasing built-in gain on the inherited asset.
- The grantor-trust path can release 100% of the losses when assets stay out of the estate.
- It avoids double-dipping disputes, giving a clear, defensible computation.
Cons:
- Most of the loss is usually lost, because the step-up often absorbs the bulk of it.
- There is no carryover to heirs, so the value disappears if not captured on the final return.
- Timing is unforgiving, with one shot on the final Form 1040.
- The grantor-trust outcome costs the step-up, so heirs inherit a lower basis.
- State treatment can differ, adding complexity for multi-state estates.
Does My State Follow This Rule?
Start with the federal rule, then check your state. Most states with an income tax begin from federal adjusted or taxable income, so they generally follow the §469(g)(2) result and the §1014 step-up as computed for federal purposes. That means the loss freed on the federal final return usually flows through to the state return as well.
But never assume. A handful of states decouple from parts of the federal passive loss or basis rules, and states like California maintain their own passive loss tracking that can produce a different suspended-loss balance than the federal figure. Always confirm with the specific state tax agency before filing.
For the nine states with no individual income tax — including Texas, Florida, Washington, and Nevada — the question is moot at the state level: there is no state income tax return to claim the loss on, so only the federal result matters.
What to Do Next
Take these steps in order to capture every dollar of deduction you are owed.
- Pin down the date-of-death fair market value of each passive activity, with an appraisal where needed, to compute the §1014 step-up.
- Pull the latest Form 8582 to confirm the exact suspended loss balance for each activity.
- Apply the formula — suspended losses minus step-up — separately for each activity, and allocate joint losses by owner.
- Determine gross-estate inclusion, especially for trust-held assets, to see if a full 100% release applies.
- Report the deductible portion on the final Form 1040, generally due April 15 of the year after death.
- Call a CPA or estate attorney if the estate holds partnerships, S corporations, multiple states, or trust assets — this is where mistakes get expensive.
This article is educational and is not a substitute for advice from a licensed CPA, tax attorney, or estate attorney for your specific situation. A professional typically reviews the basis records, computes the release, and coordinates the final return with the estate return — work that often pays for itself when large losses are at stake.
Frequently Asked Questions
Do passive loss carryovers transfer to my heirs when I die?
No. Suspended passive losses do not pass to beneficiaries. Under IRC §469(g)(2), only the portion exceeding the date-of-death step-up is deductible on the decedent’s final Form 1040; the rest is permanently lost.
How much of my suspended passive loss can be deducted at death?
The amount that exceeds the §1014 basis step-up. Subtract the step-up (fair market value minus old basis) from the total suspended losses. The remainder is deductible on the final return; the portion equal to the step-up is disallowed.
Where do I deduct the freed passive losses?
On the decedent’s final Form 1040. The released amount is an ordinary loss that can offset any income on that return, not just passive income. For a 2025 death, the return is generally due April 15, 2026.
Why does the step-up in basis reduce my deduction?
Because it eliminates the gain the loss would have offset. The §1014 step-up wipes out built-in gain, so Congress disallows the matching loss to prevent a double tax benefit, absorbing the losses dollar-for-dollar.
Can a grantor trust free up 100% of the passive losses?
Yes, in some cases. If grantor-trust assets are not included in the gross estate, they get no step-up, so the entire suspended loss is released on the final Form 1040, consistent with Field Service Advice 200106018.
What happens to my spouse’s passive losses if we filed jointly?
They keep rolling forward. Only the decedent’s passive activities run through §469(g)(2). The surviving spouse’s own suspended losses continue on the survivor’s future returns, so allocate carefully by owner.
Are passive losses treated like capital loss carryovers at death?
No, the mechanics differ. Capital loss carryovers are used on the final return up to the annual limit, then expire. Passive losses are released only to the extent they exceed the basis step-up.
Can I avoid losing the passive losses by selling before death?
Yes. A fully taxable sale of the entire activity to an unrelated party while alive releases all suspended losses, often a better result than the limited release at death.
Does the estate get to deduct the decedent’s suspended losses?
No. The decedent’s pre-death suspended losses are handled on the final Form 1040, not by the estate. The estate generates and tracks its own new passive losses going forward.
What happens to passive losses when the estate distributes the property?
They increase the beneficiary’s basis. Under IRC §469(j)(12), the estate’s own suspended losses tied to the distributed interest are added to the heir’s basis rather than deducted or passed through.
Does a gift of a passive activity work like death?
No. With a lifetime gift, no losses are deducted; instead the suspended losses are added to the recipient’s basis in the gifted activity, a different rule than the death rule.
Do all states follow the federal death rule for passive losses?
No. Most income-tax states conform, but some decouple, and states like California keep separate passive loss balances. The nine no-income-tax states do not tax the loss at all. Confirm with your state agency.
