$25K Rental Loss Write-Off: Phases Out at $150K Income

Marcus and Dana Reyes file jointly in Ohio. Marcus earns $88,000 as an operations manager; Dana brings in $9,000 from part-time work. Their combined modified AGI is roughly $97,000. They own one rental duplex that threw off a $19,000 paper loss last year — mostly depreciation, plus a new roof. Because their MAGI is under $100,000 and Marcus actively manages the property (screens tenants, sets the rent, approves repairs), they can deduct the entire $19,000 against their ordinary income. That drops their taxable income from about $97,000 to $78,000. The MFJ 12% bracket runs to $96,950 for 2026 (the 22% bracket starts at $96,951), so essentially the whole $19,000 deduction lands in the 12% bracket — the write-off saves them roughly $2,280 in federal tax (12% × $19,000) — on a loss that cost them no extra cash, because depreciation is a non-cash deduction. A higher earner whose deduction peels income off the 22% bracket would save $4,180 on the same $19,000 loss, which is exactly why the phase-out matters: the allowance is worth the most to the people the income ceiling pushes out first.

That is the $25,000 special allowance at work. It is the everyday-landlord version of the passive-loss exception — no real estate professional status, no 750 hours, no career change required. The only catch is income: the allowance is full at $100,000 MAGI, fades between $100K and $150K, and is gone above $150K.

What the $25,000 allowance actually is

Rental real estate is, by default, a passive activity under IRC §469. Passive losses can normally only offset passive income — they cannot touch your wages or your business income. That rule is what keeps most paper rental losses bottled up.

IRC §469(i) is the carve-out. If you actively participate in your rental, you may deduct up to $25,000 of net rental losses against any income — W-2 wages, 1099 income, interest, dividends — not just passive income. Congress wrote this exception specifically for ordinary landlords who are not in the real estate business full-time. It is the single most accessible way for a W-2 earner to convert a rental paper loss into a cut on their salary tax.

Active participation: a lighter test than material participation

People conflate two different standards. They are not the same, and the difference decides which rules you live under.

The good news for most landlords: you can hire a property manager and still actively participate. As long as you retain genuine decision-making authority — you set the rent, you approve the manager’s tenant recommendations, you sign off on the new water heater — you meet the active-participation test. A limited partner generally cannot meet it, and you must clear the 10% ownership floor.

The phase-out math: 50 cents on every dollar over $100K

Here is the formula that decides your number. For every dollar of modified AGI above $100,000, your $25,000 allowance drops by 50 cents:

1. Start with $25,000. That is the maximum for single, HOH, and MFJ filers.
2. Subtract 50% of (MAGI − $100,000). Only the excess over $100K counts.
3. Floor at $0. Once MAGI hits $150,000, the allowance is fully phased out.

Note the income ceilings are the same for single and MFJ — there is no marriage bonus here. A married couple gets the identical $100K–$150K band a single filer gets, which is why dual-earner households cross the threshold fast.

Worked example: MAGI $130,000, a $22,000 loss

Suppose the Reyes family from the opening gets a raise and their MAGI climbs to $130,000, and their rental throws off a $22,000 loss this year. Their allowance is now capped at $10,000 (from the table above). They deduct $10,000 against ordinary income this year. The remaining $12,000 of loss is suspended and carried forward. At a 22% marginal rate, the usable $10,000 saves them $2,200 in federal tax now; the $12,000 is parked, not lost.

Modified AGI: the number that controls everything

The phase-out runs on modified AGI, not regular AGI — and the modification works against you. For §469(i), MAGI is your AGI computed without the rental loss itself, and adding back items like IRA deductions, the student-loan-interest deduction, taxable Social Security, and a few others. Two practical consequences:

• You cannot use the rental loss to lower the MAGI that determines the rental-loss allowance. That would be circular, so the code disallows it.
• Levers that lower MAGI directly raise your allowance. A pre-tax 401(k) deferral (up to $24,500 in 2026, plus $8,000 catch-up at 50+) or an HSA contribution ($4,400 self-only / $8,750 family for 2026) reduces MAGI dollar-for-dollar. A worker at $108,000 MAGI who defers $8,000 more into a 401(k) drops to $100,000 — restoring $4,000 of allowance ($8,000 × 50%).

The arithmetic on that lever is unusually favorable, and worth seeing in full. Each dollar you move below the $100,000 line buys back 50 cents of allowance. If that reclaimed allowance is a usable loss against wages taxed at 22%, the loss itself is worth 11 cents of tax per dollar of MAGI reduction (50% × 22%) — on top of the ordinary tax saving from the deferral itself. A landlord sitting at $116,000 MAGI with a $25,000 paper loss has only a $17,000 allowance; maxing the remaining $16,000 of 401(k) room (assuming they had deferred $8,500 already) pulls MAGI to $100,000 and reopens the full $25,000. That is $8,000 of extra usable loss — about $1,760 of additional federal tax saved at 22% — that simply evaporates if they leave the contribution undone. Other MAGI levers that work the same way: deductible traditional-IRA contributions (where eligible), pre-tax FSA elections, and timing a Roth conversion out of a year you need the allowance, since conversion income raises MAGI and can shrink the very write-off you are trying to use.

One caution on the “add-backs.” The §469(i) MAGI specifically adds back the taxable-Social-Security exclusion, the IRA deduction, the student-loan-interest deduction, the foreign-earned-income exclusion, and a handful of others, and it ignores the passive loss in question. So a retiree drawing Social Security cannot assume their low taxable income keeps them under $100,000 — the untaxed portion of benefits and any IRA deduction get pulled back in for this single test. Run the §469(i) MAGI on its own worksheet rather than reusing the AGI off the front of the 1040.

Married filing separately: half the allowance, and a trap

MFS filers get a reduced version of §469(i), and one outright disqualifier:

• Lived apart all year: maximum allowance is $12,500, phasing out between $50,000 and $75,000 of MAGI (the $0.50-per-dollar rate, just on a halved band).
• Lived together at any point during the year: the allowance is $0. Not reduced — eliminated. This is a hard cliff in §469(i)(5), and it surprises couples who file separately for student-loan or liability reasons while still sharing a home.

What happens to losses above your allowance

This is the part landlords miss and it is the most valuable: disallowed losses are not gone. Under IRC §469(b), losses you cannot use this year are suspended and carried forward indefinitely. They are tracked per activity on Form 8582 and attach to the specific property. There are three ways they come back:

1. Against future passive income. If that rental (or another passive activity) turns profitable, suspended losses offset that income first.
2. Against a restored allowance in a lower-income year. If your MAGI drops back under $150K — a sabbatical, a job loss, retirement — some allowance reopens and prior suspended losses can flow through it.
3. In full when you sell. A fully taxable disposition of the entire interest to an unrelated party (§469(g)) frees all remaining suspended losses for that property — deductible against any income, including capital gains and wages, in the year of sale. This is why the $25,000 cap is a timing limit, not a permanent loss.

What most people miss

The biggest misunderstanding is treating the $25,000 cap as the end of the story. It is a deferral, not a denial. Every dollar of loss you cannot use today is banked on Form 8582 and released later — most decisively the year you sell. A landlord who stacks $12,000 of suspended losses a year for seven years walks into the sale year with $84,000+ of losses that can wipe out depreciation recapture and a chunk of the gain.

Three more under-appreciated points:

• Depreciation is what usually creates the ‘loss.’ A cash-flow-positive rental can still show a tax loss because depreciation (and, under OBBBA, 100% bonus depreciation on qualifying property placed in service after January 19, 2025) is a non-cash deduction. You are deducting a paper loss while pocketing real rent.
• The MAGI ceiling is identical for single and married couples. Two earners both pulling six figures will blow past $150K and lose the allowance entirely — at which point REPS or the short-term-rental rules become the only routes to offset W-2 income.
• Active participation must be real and documented. Keep a simple log of the decisions you make — rent you set, tenants you approved, repairs you authorized. If the IRS questions the deduction, this is your proof you cleared the active-participation bar.

Your decision: the three tiers by income

Where you land on the MAGI scale dictates the strategy:

The lever is your MAGI, and you have more control over it than the rental loss itself. If you sit just over $100,000, the highest-return move is often not finding more deductions on the property — it is shaving your MAGI back under the line with a 401(k) deferral or an HSA contribution, because each dollar you push below $100,000 restores fifty cents of write-off you can use against your salary this year. Run that number before you assume the $25,000 door is closed to you.
