Can Passive Losses Offset Capital Gains in Massachusetts? What Boston Real Estate Investors Need to Know in 2026

If you own rental property in Boston, Canton, or elsewhere in Massachusetts, you may have seen a rental loss on paper while also recognizing capital gains from another investment. That raises a practical question:
Can passive rental losses offset capital gains?
Usually, the answer is no: but there are important exceptions. The result depends on how your rental activity is classified, whether you actively participate, whether you qualify as a real estate professional, and whether the capital gain came from the passive activity itself.
This article explains the federal passive activity loss rules under Internal Revenue Code Section 469 and how those rules generally interact with Massachusetts income tax reporting for the 2025 tax year and 2026 planning.
Important: Tax rules can change, and Massachusetts may require state-specific adjustments. This is general educational information, not individualized tax advice.
The short answer: It depends on the type of capital gain
The passive activity loss rules generally separate income into three broad categories:
- Passive income, such as income from a business or rental activity in which you do not materially participate
- Nonpassive income, such as wages or income from a business in which you materially participate
- Portfolio income, such as interest, dividends, and gains from selling stocks or mutual funds
Passive losses generally can offset passive income. They generally cannot offset wages, active business income, or portfolio income.
That means a passive rental loss usually cannot offset a capital gain from selling shares of a publicly traded company or mutual fund.
However, the result can be different when:
- You qualify for the special $25,000 rental real estate allowance
- You qualify as a real estate professional and materially participate in the rental activity
- The capital gain comes from selling the passive rental property or another interest in the passive activity
- You completely dispose of your entire interest in the passive activity in a qualifying taxable transaction

How passive rental losses work
Under IRS rules, most rental real estate is treated as a passive activity: even when the owner spends meaningful time managing the property.
A passive activity generally includes:
- A trade or business in which you do not materially participate
- A rental activity, unless a specific exception applies
If your rental deductions exceed rental income, you may have a passive activity loss. That loss is generally limited to the amount of passive income you have for the year.
For example, suppose you own a small rental property in Canton that produces a $30,000 tax loss. You also have:
- $12,000 of passive income from another limited partnership
- $100,000 of wages
- $40,000 of capital gains from selling stock
The $30,000 rental loss may be used against the $12,000 of passive income. The remaining loss is generally suspended. It cannot ordinarily be used against your wages or stock-market capital gains in the same year.
The unused amount is not automatically lost. It is generally carried forward and tracked for future years.
The $25,000 active participation allowance
The first major exception is the special allowance for rental real estate activities.
If you or your spouse actively participate in a rental real estate activity, you may be able to deduct up to $25,000 of rental loss against nonpassive income. Depending on your circumstances, that may include wages, active business income, and capital gains.
Active participation is a lower standard than material participation. You may qualify by making genuine management decisions, such as:
- Approving tenants
- Setting rental terms
- Approving repairs or capital expenditures
- Arranging for property management or maintenance services
Generally, you must own at least 10% of the activity by value. Limited partners typically do not qualify as actively participating for this purpose.
The allowance is subject to a modified adjusted gross income phaseout:
- Up to $25,000 may be available when modified AGI is $100,000 or less
- The allowance is reduced by 50% of modified AGI above $100,000
- It generally reaches zero at modified AGI of $150,000 or more
For married taxpayers filing separately, different thresholds and a maximum allowance of $12,500 may apply. If you lived with your spouse at any time during the year, the special allowance generally is not available to you on a separate return.
The important distinction is that the $25,000 allowance does not automatically make the rental activity nonpassive. It is a limited exception that permits some rental losses to reduce nonpassive income.
Real estate professional status: the 750-hour rule is only part of the test
The second major exception applies to taxpayers who qualify as real estate professionals.
For a tax year, you generally must satisfy both of these requirements:
- More than half of the personal services you perform in all trades or businesses are performed in real property trades or businesses in which you materially participate
- You perform more than 750 hours of services during the year in real property trades or businesses in which you materially participate
Qualifying real property trades or businesses can include:
- Development or redevelopment
- Construction or reconstruction
- Acquisition
- Rental or leasing
- Property operations and management
- Brokerage
But meeting the 750-hour threshold by itself is not enough. You must also materially participate in the rental activities you want treated as nonpassive.
Common material participation tests include:
- Participating in the activity for more than 500 hours
- Participating more than any other individual involved in the activity when you work more than 100 hours
- Participating on a regular, continuous, and substantial basis under the facts-and-circumstances test
- Meeting certain prior-year participation tests
A real estate professional may also be able to elect to group multiple rental properties into one activity for material participation purposes. That election can be significant for an investor with several Boston-area properties, but it should be evaluated carefully because grouping can affect both current deductions and future dispositions.
Keep records that support your position. Calendars, property-management records, emails, contractor communications, leasing activity, travel records, and narrative summaries may all help document participation. The IRS does not necessarily require a contemporaneous daily time log, but you should be able to substantiate your hours and activities using reasonable evidence.

When a gain from rental property can absorb passive losses
The passive activity rules treat gain from the disposition of an interest in a passive activity, or property used in a passive activity, as passive activity income in many circumstances.
So, if you sell a rental property that has been treated as passive, suspended passive losses may be available to offset the gain from that activity under the passive loss rules.
This is different from selling an unrelated investment. For example:
- Gain from selling a passive rental property may be passive activity income
- Gain from selling stock held for investment is generally portfolio income
That distinction is often the key to answering whether passive rental losses can offset capital gains.
Complete disposition can release suspended losses
When you dispose of your entire interest in a passive activity in a fully taxable transaction to an unrelated party, previously disallowed passive losses are generally allowed in full for that year.
A qualifying disposition generally requires:
- Disposal of your entire interest, or an interest treated as substantially all under specific rules
- A transaction in which the realized gain or loss is recognized
- A buyer who is not related to you
Once released, the suspended losses are no longer limited by the passive activity rules. They may reduce overall taxable income, subject to other limitations that could apply, including basis, at-risk, capital-loss, and excess-business-loss rules.
A partial sale, gift, related-party transfer, or certain installment transactions can produce a different result.
How Massachusetts generally fits into the picture
Massachusetts has its own income tax rules, forms, and adjustments. However, Massachusetts Department of Revenue guidance addresses the state treatment of passive activity losses under IRC Section 469, and Massachusetts generally begins with federal income amounts before applying state-specific modifications.
For many Massachusetts investors, this means:
- A passive rental loss disallowed federally generally is not currently deductible on the Massachusetts return
- A loss allowed federally may generally flow into Massachusetts income calculations, subject to state adjustments
- Released suspended losses may need to be reflected through Massachusetts reporting and reconciliation rules
- Federal and Massachusetts treatment may differ where depreciation, basis, entity, or other state adjustments apply
Review the Massachusetts DOR guidance on passive activity losses and the applicable Massachusetts return instructions for the filing year.
If you have Massachusetts rental property and capital gains, do not assume that a federal Form 8582 result tells the entire state story. A property-by-property review may be necessary, especially if you own properties through partnerships, S corporations, or multiple LLCs.
A practical checklist for Boston-area investors
Before deciding whether your passive rental losses can offset capital gains, gather:
- The source of each capital gain
- Your current-year rental income and deductions
- Prior-year suspended losses by activity
- Your modified AGI
- Ownership percentages for each rental activity
- Records showing management involvement
- Hours spent in real property trades or businesses
- Whether you materially participated in each rental
- Whether you made a grouping election
- Federal and Massachusetts depreciation and basis information
A tax advisor can then model the result rather than looking only at the total loss shown on Schedule E.
What to do if your tax situation is getting more complex
Passive rental losses, capital gains, real estate professional status, multiple properties, and Massachusetts reporting can quickly become interconnected. The right answer may change from year to year as your income, property activity, ownership structure, and participation change.
If you are unsure how your rental losses should be classified: or you are planning a sale, adding properties, or tracking growing suspended losses: consider starting with a Tax Clarity Assessment™. It is a lower-friction way to organize the facts, identify the key tax questions, and determine whether a deeper planning or compliance review makes sense.
You can also review GotIRSProblems Accounting & Advisory’s real estate investor tax complication services or start with the firm’s case review. The goal is not to promise a particular tax result. It is to help you understand what applies, what documentation matters, and what decisions should be evaluated before filing or selling.
