Passive Loss Carryover: How Unused Rental Losses Carry Forward

By Hans Goldstein · Updated 2026-09-27

A passive loss carryover is a passive activity loss you could not deduct this year, carried forward to next year and every year after, with no expiration date (§469(b)). It stays attached to the activity that produced it and waits for one of four things: passive income, the $25,000 rental allowance, a fully taxable sale of that activity, or your death. It cannot offset wages or stock gains in the meantime.

The rules sound simple. The details decide whether your carryover is worth a lot, a little, or nothing, and whether you use it this decade or never.

The rule in one paragraph

Under Section 469, a loss from a passive activity (a rental, or a business you do not materially participate in) can offset only income from passive activities. Any excess is disallowed for the year and treated as a deduction from the same activity in the next year (§469(b)). The Form 8582 instructions list the ways out: carried-forward losses are allowed "either against passive activity income; against the special allowance, if applicable; or when you sell or exchange your entire interest in the activity in a fully taxable transaction to an unrelated party." There is no limit on the number of years.

What passive income can absorb the carryover

Any net passive income, from any passive activity, absorbs carried-over losses from all of them. That includes:

• A rental with taxable profit, after its own depreciation.
• K-1 income from a limited partnership or LLC deal you do not work in, once it starts paying out.
• Gain from selling a rental or a passive business interest, including depreciation recapture (Temp. Reg. §1.469-2T(c)(2)(i)(A)).
• Gain on a sale reported on the installment method, in each year it is recognized, if the activity was passive in the year of sale (and, for appreciated property that was ever nonpassive, passive for the 24 months before the contract or 20% of your holding period, Reg. §1.469-2(c)(2)(iii)).

And what it cannot absorb:

A special case: losses from a publicly traded partnership can offset only income from that same partnership until you dispose of your entire interest in it.

Can passive losses offset capital gains?

This is the most searched question about carryovers, and the answer is only if the capital gain is passive.

Gain on selling a passive rental is capital gain (and some §1231 and recapture income), and it is passive. So yes, your carryover offsets it. Gain on selling a public stock, a mutual fund or a lot you held for appreciation is capital gain too, but it is portfolio income, and the carryover cannot touch it.

Do not confuse passive losses with capital losses, which follow different rules. A capital loss carryforward offsets capital gains of any kind, passive or not, dollar for dollar, but only $3,000 a year of ordinary income (§§1211(b), 1212(b)). An investor whose advisor harvests capital losses in a stock account has a second kind of reservoir.

The book's Case 7 (an illustrative composite; engine output) is that investor: about $120,000 a year of harvested capital losses and a rental condo with a $930,000 gain. Sold for cash, the tax on the gain was about $283k. Sold over six years so each slice of gain met that year's harvested losses, it was about $100k, all of it in year one.

The $25,000 allowance and the MAGI phase-out

The one way most landlords use rental losses against wages without a sale:

• You must actively participate (approve tenants, set rents, approve repairs) and own at least 10% by value. Limited partners never qualify (§469(i)(6)).
• Up to $25,000 a year of rental losses offsets other income.
• It shrinks by 50 cents per dollar of modified AGI over $100,000 and is gone at $150,000 (§469(i)(3)). Modified AGI for this purpose ignores passive losses and the taxable part of Social Security, among other items listed in the Form 8582 instructions.
• Married filing separately: $12,500 with a $50,000 to $75,000 phase-out if you lived apart all year; zero if you lived together at any time.

Whatever the allowance does not cover joins the carryover. Line by line, this is Part II of Form 8582.

Tracking carryovers by activity, and why it matters at sale

Your carryover is not one number. It is a set of numbers, one per activity.

When passive income covers only part of the year's losses, the disallowed loss is allocated among your loss activities in proportion to their losses (Temp. Reg. §1.469-1T(f)(2)(i)), and the carryover keeps its identity by activity and by type of deduction (Reg. §1.469-1(f)(4)). On Form 8582, that is Part VII, column (c).

That matters because a fully taxable sale of your entire interest in an activity to an unrelated buyer releases that activity's carryover against any income (§469(g)). Not everyone's. Just its own.

A simple example: This year Rental A loses $30,000 and Rental B loses $10,000. A limited partnership K-1 shows $8,000 of income. Net passive loss: $32,000, none of it allowed (the couple's modified AGI is over $150,000). Allocated by ratio: A carries $24,000 ($30,000 x 30/40) and B carries $8,000 ($10,000 x 10/40).

Next year they sell Rental B for a $50,000 gain to an unrelated buyer, fully taxable, while A loses another $30,000. B's $50,000 gain is passive income. Netted within B, its own $8,000 carryover leaves B with a $42,000 overall gain, which absorbs $42,000 of A's $54,000 of current and carried-over loss. A still carries $12,000 into the following year (simple example).

Grouping changes all of this. If A and B are grouped as one activity (Reg. §1.469-4), or you made the real estate professional aggregation election (Reg. §1.469-9(g)), selling B is not a disposition of an entire activity and releases nothing on its own. Know your grouping before you plan a sale.

Character: not every carried-over dollar is equal

A carryover keeps the character of the items inside it. Operating losses and depreciation are ordinary. A K-1 can also carry §1231 losses and, sometimes, capital losses, and Form 8582's Part IX exists to keep those separate. The character decides what a released loss does:

• Ordinary losses come off your ordinary income first when released, which is the top of your tax bracket, while any gain keeps its capital-gain rate. The book calls that the rate swap; see what happens to suspended losses when you sell.
• §1231 or capital losses net against gain instead, and the benefit shrinks.

Ask your CPA or the sponsor for the character breakdown before you plan around a number.

Losses that are not really stuck

The book's list of carryovers that turn out smaller than they look:

• Losses stuck at basis or at-risk. A K-1 loss must clear partner basis (§704(d)) and at-risk (§465) before §469 applies. Those losses are not on Form 8582, and passive gain does not free them.
• Losses already being used. If your deals now pay out passive income, your "losses" are absorbed every year and nothing carries forward. A seller with an empty Form 8582 has no reservoir.
• A professional's losses. If you qualify as a real estate professional and materially participate, your rental losses are nonpassive and already offset your income. There is no carryover to plan around.
• Sponsor projections. Deals refinance, sell early and turn to income. Future losses are an estimate, not a promise.
• The next limit. Losses that clear §469 can still be capped by the excess business loss rule if the activity is a trade or business: $512,000 joint for 2026 (Rev. Proc. 2025-32), with the excess becoming a net operating loss usable against 80% of later taxable income.

The ways a carryover leaves

Use them or lose them. A passive carryover ends with you. Your heirs inherit the building, not your Form 8582. For a building that has gone up in value, the step-up at death can absorb most or all of its suspended losses. And carryovers from syndications and other rentals are worth something only while you have passive income for them to meet.

Turning a carryover into a plan

The practical question is not whether your losses will be used someday. It is when, and against income taxed at what rate.

A rental sale is the largest block of passive income most owners ever create. Sold for cash, the gain meets your carryover once, and then the losses your remaining rentals and deals keep producing have nothing to meet. Sold on an installment schedule, a slice of passive gain arrives every year, meeting that year's new losses as well as the old ones. The book calls that the waterfall, and it works only when the losses are really stuck. The installment sale guide explains it, and the free book walks through ten cases where it works and three where it does not.

California keeps its own carryover (FTB 3801), which differs from the federal one because the state allows no bonus depreciation and ignores professional status. Plan both.

Bottom line

Passive losses you cannot use carry forward indefinitely, activity by activity, and keep their character. They offset only passive income, including gain on selling a rental, not wages, stock gains or note interest, unless the $25,000 allowance, professional status or a fully taxable sale of the entire activity frees them. They die with you. Know your number, know its character and know your grouping, then decide when to create the gain that uses it.

Questions to ask your CPA

• What is my passive carryover, by activity, from Part VII of last year's Form 8582?
• How much of it is ordinary, §1231 or capital in character?
• Are any losses stuck at basis or at-risk, and not on Form 8582 at all?
• Are my rentals grouped, or is an aggregation election in force?
• Do I get any of the $25,000 allowance, and would a sale year take it away?
• Which carryovers would a sale of this building release: its own, the others', or both?
• What is my California (or other state) carryover next to the federal one?
• How many more years of passive losses do I expect, and would timing the gain to meet them change my tax?
