A High-Level Guide to What You Can (and Can’t) Write Off
Owning a home comes with a lot of costs, but it can also come with some meaningful tax benefits. The challenge is that many of those benefits are not automatic, and some only apply if you take specific steps when filing your taxes.
This guide walks through the most common tax deductions and credits for homeowners, how they work, when they apply, and where people often get tripped up.
We’ll keep it high-level, practical, and focused on what matters most for a broad national audience.
Do You Have to Itemize to Get These Benefits?
Before getting into specific deductions, there’s one key concept to understand:
Most homeowner tax deductions only apply if you itemize.
Instead of taking the standard deduction, itemizing means:
- listing out specific expenses (mortgage interest, property taxes, etc.)
- adding them together
- comparing that total to the standard deduction
You only benefit if your itemized deductions are higher than the standard deduction.
What that means in practice
- If you take the standard deduction, you won’t claim most homeowner deductions
- If you itemize, you may reduce your taxable income more—but it requires:
- more documentation
- more record-keeping
- more attention to detail
There is real upside here—but it’s not passive. It requires some effort and consistency.
Mortgage Interest Deduction
This is often the most well-known homeowner deduction.
How it works
You may be able to deduct the interest you pay on your mortgage, especially if the loan was used to:
- buy the home
- build the home
- substantially improve the home
Limits to be aware of
For many homeowners:
- interest is generally deductible on up to $750,000 of mortgage debt for newer loans
Older loans (pre-2017) may follow different limits.
Why it matters
In the early years of a mortgage, a large portion of your payment is interest, so this deduction can be meaningful if you itemize.
Property Tax Deduction (SALT)
Homeowners can often deduct state and local taxes (SALT), including:
- property taxes
- state income taxes (or sales tax)
Current limits (with important caveats)
Historically, this deduction was capped at $10,000, but newer legislation has increased that cap to as much as $40,000 for certain tax years, depending on income and filing status.
Why the caveat matters
This is an area that changes frequently with tax law, and the numbers above apply to most recent timeframes as of the writing of this piece in the Spring of 2026. Bottom line, you must check what is recent and applicable for yourself. Caps, phaseouts, and timelines can shift.
If this deduction is important to you, it’s worth:
- checking the latest IRS guidance
- or asking a tax professional how current limits apply to your situation
Home Equity Loan and HELOC Interest
Interest on a home equity loan or HELOC may be deductible, but only in certain situations.
Key rule
You can typically deduct interest only if the loan is used to:
- buy
- build
- or substantially improve the home securing the loan
What does NOT qualify
Using a HELOC for:
- credit card consolidation
- personal expenses
- vacations
…usually does not qualify for interest deduction.
This is a common misunderstanding.
Mortgage Points (Discount Points)
If you paid points when you got your mortgage, you may be able to deduct them.
What are points?
Points are essentially prepaid interest used to lower your interest rate.
Because of that:
- they are often deductible as mortgage interest
Important distinction
Not all closing costs are deductible. For example:
- origination fees
- underwriting fees
…are generally not deductible in the same way.
Tax Credits vs. Tax Deductions (Important Distinction)
Many homeowners confuse these two.
Tax deduction
Reduces your taxable income
Tax credit
Reduces your tax bill directly
Credits are often more powerful.
Energy Efficiency Tax Credits
Homeowners may qualify for federal tax credits for certain upgrades.
Examples of qualifying improvements
- windows and doors
- insulation
- HVAC systems
- heat pumps
- solar panels
Typical credit structure
- Around 30% of qualifying costs
- Annual limits may apply depending on the improvement
For example:
- energy-efficient upgrades may qualify for up to $1,200 annually
- some systems (like heat pumps) may qualify for higher limits
Timing matters
Many of these credits:
- have expiration dates
- or change based on legislation
So it’s worth verifying current rules before making large upgrades.
Mortgage Interest Credit (Less Common)
Some homeowners may qualify for a Mortgage Interest Credit, which directly reduces taxes.
This typically applies if:
- you received a Mortgage Credit Certificate (MCC) from a state or local program
This is not common for all buyers, but it can be valuable if you qualify.
Capital Gains Exclusion When You Sell
This isn’t a deduction—but it’s one of the biggest tax benefits of homeownership.
The rule
If you sell your primary residence, you may exclude:
- up to $250,000 in gains (single)
- up to $500,000 (married filing jointly)
Basic requirement
You must have:
- owned the home, and
- lived in it
for at least 2 of the last 5 years
Why this matters
In strong housing markets, this exclusion can significantly reduce or eliminate taxes on gains.
By The Way: Other Situations
These may apply in specific cases:
Rental or partial-use homes
- Expenses may be partially deductible
- Rules become more complex (often require allocation)
Home office deduction
- Generally available for self-employed individuals
- Based on square footage or actual expenses
These situations can introduce more complexity, so many homeowners seek professional guidance when they apply.
What You Can’t Deduct
Knowing what you can’t deduct is just as important as what you can deduct. Trying to deduct items you shouldn’t is a huge red flag for the IRS.
Common non-deductible expenses include:
- homeowner’s insurance
- utilities
- general home repairs
- HOA fees
- domestic help or services
These costs may still matter financially—but they typically don’t reduce your taxable income.
When Homeowner Deductions Actually Make a Difference
Not every homeowner benefits equally.
You’re more likely to benefit if:
- your mortgage interest is high (earlier in loan)
- you live in a higher-tax area
- your total deductions exceed the standard deduction
- you’ve made qualifying improvements
If your expenses don’t exceed the standard deduction, itemizing may not provide additional benefit.
How to Get the Most Value (Without Overcomplicating It)
A few practical takeaways:
Keep records throughout the year
Don’t wait until tax season to gather:
- mortgage interest statements
- property tax bills
- receipts for improvements
Know what qualifies before you spend
Especially for:
- HELOC usage
- energy upgrades
Pay attention to timing
Some strategies involve grouping deductions into a single year to exceed the standard deduction. Splitting expenses into the end of one year, and into the beginning of the next can really impact what you are able to deduct.
Stay current on tax law
Items like:
- SALT caps
- energy credits
…can change from year to year.
The Bottom Line
Homeownership can come with meaningful tax advantages—but they are not automatic.
The biggest levers typically include:
- mortgage interest
- property taxes (SALT)
- qualifying home improvement credits
- capital gains exclusion on sale
And in most cases, those benefits depend on whether you itemize your deductions.
Because tax rules can vary based on income, state, and changing legislation, it’s often worth taking the time to understand your options, or getting a second opinion.
If you’re unsure how these deductions apply to your situation, consider speaking with more than one tax professional or financial advisor. Comparing guidance can help you better understand what you qualify for and how to make the most of your homeownership from a tax perspective.
