If you own rental real estate, two rules can quietly change your tax bill: depreciation and the passive activity loss rules. For the 2025 tax year filed in 2026, this matters even more if your return is extended, because the extra time can help you get the basis, records, and loss calculations right before you file.
Quick takeaways
- Residential rental buildings are generally depreciated over 27.5 years under the mid-month convention; land is not depreciable.
- Rental activity is generally passive, even if you spend time managing it, unless you qualify as a real estate professional.
- If you actively participate in rental real estate, you may qualify for up to a $25,000 special allowance, but it phases out as MAGI rises above $100,000 and disappears at $150,000; the MFS thresholds are lower.
- Passive losses not allowed in the current year generally carry forward until you have passive income, use the special allowance, or dispose of your entire interest in a fully taxable transaction.
- For an extended 2025 return, the filing deadline is generally October 15, 2026 if you requested an extension by the April deadline; the extension does not extend the time to pay tax due.
Who this applies to
This article is for individual taxpayers who report rental real estate on Schedule E (Form 1040), including people who own one rental house, several units, or a rental property held through a pass-through structure that shows up on their personal return. If your rental is owned through a partnership or S corporation, your share may come to you on a Schedule K-1 and still be subject to the individual passive-loss rules on your return. Corporations follow different passive-loss forms and rules. This is a federal guide; state treatment may differ.
Introduction
For the 2025 tax year filed in 2026, the biggest rental-property mistakes are usually not about whether the property made money. They are about what can be depreciated, how much loss is currently deductible, and which form captures the limitation. The IRS says rental activities are generally passive, and current-year passive losses are often limited even when the property generated a real cash loss. If you are on extension, this is the year to make sure you have the correct purchase documents, land allocation, improvement records, and prior-year loss carryforwards before the return is filed.
What rental property depreciation is
Depreciation is the annual tax deduction that lets you recover the cost of income-producing property over time. For residential rental property, the IRS generally uses 27.5 years and the mid-month convention under MACRS. That means the building is treated as if it were placed in service at the midpoint of the month you first rented it, which affects the first and last year’s deduction.
A few core rules matter right away:
- You can depreciate only the part of the property used for rental purposes.
- Land is not depreciable, so you must split the purchase price between land and building.
- If you converted a personal home to rental use, the depreciation basis is generally the lesser of fair market value or adjusted basis on the conversion date.
- Depreciation reduces your basis for a later sale, and the IRS says you must reduce basis by depreciation allowed or allowable, even if you forgot to claim it.
- If the property is temporarily idle, you generally keep depreciating it while it is still in the rental activity.
What gets reported where
If you first place depreciation-relevant property in service during 2025, or if you start a section 179 deduction or amortization in 2025, you generally must attach Form 4562, Depreciation and Amortization. Residential rental depreciation itself is usually computed from the property’s basis, recovery period, and placed-in-service date, with the numbers flowing to your rental schedule.
How passive loss rules work
The IRS treats two broad categories as passive activities:
- trade or business activities in which you do not materially participate, and
- rental activities, even if you do participate, unless you are a real estate professional.
That means a rental loss is often not freely deductible against wages, interest, dividends, or other nonpassive income. Instead, the loss may be limited on Form 8582, Passive Activity Loss Limitations. Current-year losses that are not allowed generally carry forward until they can be used against passive income, the special allowance, or upon a fully taxable disposition of the activity.
Active participation is not the same as material participation
For the special rental real estate allowance, the IRS uses a lighter standard called active participation. It is not the same as material participation. The IRS says active participation can include making management decisions such as approving tenants, setting rental terms, and approving expenditures. It is available only to individuals, and you generally need at least a 10% ownership interest by value.
That matters because active participation can unlock a limited current-year deduction even if the activity is still technically passive. But for high-income filers, the phaseout often wipes out that benefit.
The $25,000 special allowance
For 2025, the special allowance for rental real estate losses with active participation is up to $25,000. It is reduced by 50% of the amount your MAGI exceeds $100,000. If your MAGI is $150,000 or more, you generally cannot use the special allowance. For married filing separately taxpayers, the maximum is $12,500 if you lived apart all year, with a lower phaseout range. If you lived with your spouse at any time during the year, you generally cannot use the special allowance.
Real estate professional exception
If you qualify as a real estate professional and materially participate in the rental activity, rental real estate losses may be treated as nonpassive instead of being routed through the passive-loss limitation rules. The IRS says you must meet both of these tests: more than half of your personal services in all trades or businesses must be in real property trades or businesses in which you materially participate, and you must perform more than 750 hours of services in those trades or businesses during the year.
At-risk rules come first
The IRS says you must apply the at-risk rules before the passive-loss rules. If you are not at risk for some of the investment, you may need Form 6198, At-Risk Limitations, before Form 8582 even comes into play. In other words, depreciation, basis, at-risk, and passive-loss limits are separate layers, and the order matters.
Why the extended filing season matters
An extension gives you time to get the rental return right, but it does not change the underlying tax rules. For a 2025 return, most individual filers can extend the filing deadline to October 15, 2026 if they request the extension by April 15, 2026. The IRS is clear that an extension is extra time to file, not extra time to pay.
That extra time is useful because rental depreciation and passive-loss calculations often depend on documents people gather late:
- closing statements and purchase price allocation,
- land-versus-building allocation,
- receipts for improvements and repairs,
- prior-year Form 8582 carryforwards,
- K-1s from partnerships or S corporations,
- and records showing when the property was placed in service.
If you missed depreciation in a prior year, do not assume it is harmless. The IRS says your basis must still be reduced by the depreciation you were allowed or allowable to claim.
Forms and schedules involved
| Form or schedule | What it is used for | Key 2025 point |
|---|---|---|
| Schedule E (Form 1040) | Reports rental income, expenses, and depreciation for most individual landlords. | If your rental is on a personal return, this is usually the main schedule. |
| Form 4562 | Reports depreciation and amortization. | Generally required if property is first placed in service in 2025, or if section 179/amortization begins in 2025. |
| Form 8582 | Computes current-year passive activity loss limits and applies prior-year carryforwards. | Used by individuals, estates, and trusts with passive losses. |
| Form 6198 | Applies at-risk limits before passive-loss limits. | File if part of the loss is not at risk. |
How this differs for individuals vs. businesses
For individuals, rental real estate usually lands on Schedule E, then flows through depreciation and passive-loss calculations on the personal return. Individuals may also qualify for the active-participation allowance, which is not available to entities as such.
For partnerships and S corporations, the entity may report rental real estate items on a Schedule K-1, and the owner still has to apply the individual limitations on the return. The IRS instructions specifically say that for losses from a partnership or S corporation, the allowable loss from the K-1 is entered on Schedule E. Corporations are different; the IRS says corporations subject to the passive-activity rules use Form 8810 instead of Form 8582.
Common mistakes
- Treating the building and land as one asset. Land is not depreciable, so you must split the purchase price.
- Forgetting the mid-month convention. Residential rental property does not use the same convention as many shorter-life assets.
- Assuming every rental loss can offset wages. Passive losses are generally limited unless you qualify for an exception.
- Confusing active participation with real estate professional status. They are not the same test.
- Ignoring prior-year suspended losses. They carry forward and can become deductible later, but only under the IRS ordering rules. (Missing depreciation on an extended return. Extra filing time does not erase the need to track basis, improvement dates, and carryforwards accurately.
Myth vs. fact
Myth: If my rental loses money, I can deduct the whole loss right away. Fact: Not necessarily. Rental losses are usually passive and may be limited by at-risk rules, the passive-loss rules, or both.
Myth: If I file on extension, depreciation and passive-loss rules are easier. Fact: The extension only gives you more time to file. The underlying calculations still follow the same 2025 rules.
Practical examples
Simplified illustrations only. These examples are educational, not a substitute for your actual return.
Example 1: Active participation, but the loss is partly allowed
A single taxpayer has $120,000 of wages and a $31,000 loss from rental real estate in which they actively participated. Because MAGI is over $100,000 but below $150,000, the special allowance is reduced to $15,000. The taxpayer deducts $15,000 this year and carries forward $16,000 to 2026. This is the IRS’s own 2025 example structure.
Example 2: High-income filer, no special allowance
A single filer has $240,000 of MAGI and a $18,000 rental loss from a property they actively manage but do not materially participate in as a real estate professional. Because MAGI is above $150,000, the IRS says the special allowance generally disappears. In that case, the loss is generally suspended on Form 8582 and carried forward until it can be used later.
Example 3: Converting a former home to a rental
A taxpayer converts a former home into a rental in 2025. The property’s adjusted basis is $340,000, but the fair market value on the conversion date is $310,000. The house portion of the property is the only depreciable part, because land is not depreciable. The depreciable basis is therefore $310,000, and the building is recovered over 27.5 years under the residential rental rules. The first-year deduction will still be a partial-year amount because of the mid-month convention.
Example 4: A rental property is temporarily vacant
A landlord’s unit is empty for two months between tenants while repairs are made. The property is still part of the rental activity, so depreciation generally continues during the vacancy. That does not create a special deduction by itself, but it does mean the yearly depreciation schedule does not stop just because the unit is temporarily idle.
Checklist: what to gather before you file an extended 2025 return
- Purchase settlement statement and closing documents.
- A reasonable land-versus-building allocation.
- Dates the property was placed in service and taken out of service, if applicable.
- Improvement and repair records, including dates and amounts.
- Prior-year Form 8582 carryforwards and any Form 6198 limitations.
- K-1s from partnerships or S corporations, if the rental is held through a pass-through entity.
- Any facts showing active participation or real estate professional status.
FAQ
Is rental real estate always passive?
Usually, yes. The IRS says rental activities are passive even if you materially participate, unless you qualify as a real estate professional.
Can a high-income taxpayer still deduct rental losses?
Sometimes. If you actively participate, you may get the $25,000 special allowance, but it phases out at higher MAGI levels and usually disappears at $150,000 of MAGI. If you qualify as a real estate professional, the loss may be treated as nonpassive.
Do I need Form 4562 every year for a rental?
Not always, but you generally need it if property is first placed in service in 2025 or if a section 179 deduction or amortization begins in 2025.
What happens to losses I cannot deduct this year?
They generally carry forward until you have passive income, the special allowance applies, or you dispose of your entire interest in a fully taxable transaction to an unrelated party.
Do partnerships and S corporations change the answer?
The ownership structure changes the paperwork, but not the basic concept for the individual owner. Rental items may flow through on a Schedule K-1, and the owner still has to apply the passive-loss rules on the personal return.
What if I missed depreciation in an earlier year?
Do not assume it is gone. The IRS says basis must still be reduced by depreciation allowed or allowable, so a missed deduction can affect your basis and future gain or loss.
Bottom line
For 2025 returns filed in 2026, rental property depreciation and passive-loss limits can materially change what a high-income taxpayer can deduct now versus later. The biggest checks are simple but important: split land from building, use the correct recovery period, know whether you qualify for active participation or real estate professional treatment, and carry the losses to the right form. If your rental return is extended, use the extra time to get the records right before you file.
What to do next
- Confirm your depreciable basis and land allocation for each rental.
- Recheck whether you need Form 4562, Form 8582, or Form 6198.
- Pull prior-year suspended losses before you file an extended return.
- If you think you qualify as a real estate professional, document your hours carefully.
- If your facts are messy or you own multiple rentals, consider a CPA, EA, or tax attorney before filing. This is especially important if you converted a home to rental use, have K-1 income, or need to correct missed depreciation.
