Work out how much of your rental loss is deductible now under IRC §469, how much phases out between $100,000 and $150,000 of MAGI, and the suspended loss you carry forward to a future year.
The special allowance lets a rental owner with MAGI at or below $100,000 deduct up to $25,000 of rental loss against ordinary income. Above $100,000 it shrinks by 50 cents per dollar and disappears at $150,000. Every figure below is produced by this page's own formula.
| Scenario | MAGI | Rental Loss | Allowance | Deductible | Carried Forward |
|---|---|---|---|---|---|
| Low Earner | $80,000 | $20,000 | $25,000 | $20,000 | $0 |
| Mid Phase-Out | $120,000 | $20,000 | $15,000 | $15,000 | $5,000 |
| High Earner | $160,000 | $25,000 | $0 | $0 | $25,000 |
| No Active Participation | $90,000 | $18,000 | $0 | $0 | $18,000 |
The Low Earner can deduct the entire $20,000 loss because it is below the $25,000 ceiling. The Mid Phase-Out taxpayer has $20,000 of MAGI above the $100,000 threshold, so the allowance drops to $15,000 — the loss beyond that is suspended, not lost. The High Earner gets no current deduction at all: the entire $25,000 is suspended and becomes usable when the property is sold or when income falls.
The maximum allowed rental loss by MAGI (active participation, loss large enough to use it):
| MAGI | Max Allowance | Reduction from $25,000 |
|---|---|---|
| $100,000 or less | $25,000 | $0 |
| $110,000 | $20,000 | $5,000 |
| $120,000 | $15,000 | $10,000 |
| $130,000 | $10,000 | $15,000 |
| $140,000 | $5,000 | $20,000 |
| $150,000 or more | $0 | $25,000 |
Under IRC §469, losses from a "passive activity" — which by default includes nearly every rental property — cannot offset wages, business income, or portfolio income. They can only offset other passive income. Congress carved out two relief valves: the $25,000 rental allowance and Real Estate Professional status.
"Active participation" just means you make management decisions — approving tenants, setting rents, authorizing repairs. You do not need to swing a hammer, and a property manager does not disqualify you.
If you spend more than 750 hours per year in real property trades or businesses and materially participate in each rental, the losses are no longer passive at all. They offset ordinary income without the $25,000 limit and without the phase-out. This is the single largest tax distinction in real estate.
Modified AGI is your adjusted gross income computed without the passive loss deduction itself, but it does include almost everything else — wages, business income, capital gains, and retirement distributions. A one-off capital gain can therefore push you over $150,000 and wipe out the allowance for that year.
1. Time your capital gains. A large gain in the same year as a rental loss can eliminate the $25,000 allowance entirely. Roth conversions have the same effect.
2. Buy passive income to absorb the losses. Losses offset passive income from other rentals or a passive LP interest — unlimited by the $25,000 cap.
3. Track suspended losses religiously. They carry forward and are released on an installment basis at sale; missing the record costs real money.
4. Consider Real Estate Professional elections. If you or a spouse can document 750+ hours, the $25,000 limit stops applying — often the biggest deduction available to a two-property owner.
A rental property that shows a paper loss is a common and intentional outcome — mortgage interest, property tax, insurance, repairs, and depreciation routinely exceed rent in the early years. Owners naturally expect that loss to reduce their tax bill, and for most of them it does not, at least not immediately.
The reason is that Congress categorizes every income stream as active (wages, business), portfolio (dividends, interest, capital gains), or passive (rentals, limited partnerships). Passive losses may only offset passive income. A landlord with a W-2 salary and one rental therefore has a loss they cannot use — until the $25,000 allowance kicks in below the income threshold, or the property is sold.
Tax law sorts income into three buckets, and losses can only cross within a bucket:
| Bucket | Examples | Can Passive Losses Offset It? |
|---|---|---|
| Active | Wages, salary, a business you materially participate in | Only via the $25,000 allowance (or REP status) |
| Passive | Rental income, LP interests, businesses you do not run | Yes — unlimited |
| Portfolio | Dividends, interest, capital gains, annuities | No — never, at any income level |
The mismatch is why two otherwise identical landlords can face very different tax bills: the one with other passive income absorbs the loss immediately, the one who relies on wages cannot.
