The Tax Benefits of Owning a Home

Chad Dickinson • December 5, 2025

Owning a home doesn’t just build long-term wealth — it can also unlock meaningful tax savings each year. Some benefits reduce the income you’re taxed on (deductions), while others cut your tax bill dollar-for-dollar (credits). Knowing which rules apply to your situation can be worth hundreds or even thousands of dollars at filing time.


Below is a clear, up-to-date breakdown of the most valuable federal homeowner tax perks for the 2025 tax year, plus what to document so you don’t miss a thing.


Key Takeaways

  • Homeowners may qualify for major tax deductions (mortgage interest, property taxes, points, some home-equity interest) and tax credits (energy-efficiency upgrades, renewable energy systems, Mortgage Credit Certificates). IRS+1
  • The mortgage interest deduction generally lets itemizers deduct interest on up to $750,000 of qualifying mortgage debt ($375,000 if married filing separately).
  • The property tax deduction is part of the SALT limit: $10,000 cap through 2024 and $40,000 cap for 2025 (with a phase-out for higher incomes).
  • Energy credits are a “use-them-now” deal in 2025: §25C and §25D credits remain at 30% but expire after December 31, 2025 under current law.
  • Qualifying lower- and moderate-income buyers with a Mortgage Credit Certificate (MCC) can claim a mortgage interest credit up to $2,000/year.
  • When selling a primary residence, eligible homeowners can exclude up to $250,000 of capital gains ($500,000 for joint filers). IRS


Deductions vs. Credits: What’s the Difference?

Before diving into specifics, it helps to know how these two tax breaks work:

  • Tax deductions reduce your taxable income.
    Example: If you earn $80,000 and claim $6,000 in deductions, you’re taxed on $74,000 instead.
  • Tax credits reduce your tax bill directly.
    Example: If you owe $3,000 and claim a $1,000 credit, your final bill drops to $2,000.


Most homeowner benefits are deductions — but a few credits can be even more powerful because they lower taxes dollar-for-dollar.


1. Mortgage Interest Deduction

For many homeowners who itemize, mortgage interest is the biggest tax break available. You can generally deduct interest paid on loans used to buy, build, or substantially improve your main home or one second home. IRS+1


Key Rules

  • Interest is deductible on up to $750,000 of qualifying mortgage debt for loans originated after December 15, 2017. Nolo+1
  • If your mortgage is older than that, the limit may be $1 million. IRS
  • Married filing separately: $375,000 cap for newer loans. Tax Shark
  • You must itemize deductions on Schedule A to claim it. IRS+1


Example

If you bought a home for $600,000 in 2022 and paid about $35,000 in mortgage interest this year, you could deduct that full amount if you itemize.


Documentation: Your lender sends Form 1098 every January showing your deductible interest.


2. Property Tax Deduction (SALT)

Property taxes can also be deductible if you itemize — but they fall under the State and Local Tax (SALT) cap. IRS+1


What Counts

You can deduct real estate taxes assessed uniformly on your property value and charged yearly by your local tax authority.


Not deductible: utility charges, HOA fees, trash/water fees, or special assessments for improvements like sidewalks unless separately stated as maintenance. IRS


SALT Limits (Big Change in 2025)


  • 2018–2024: SALT deduction capped at $10,000 per return ($5,000 MFS).
  • 2025: cap increases to $40,000 ($20,000 MFS).
  • Phase-out: the $40,000 cap begins shrinking for taxpayers with MAGI over $500,000 and drops back to $10,000 at about $600,000. Kiplinger+1


Escrow Tip

If you pay taxes via escrow, deduct only what your lender actually paid out during the year — not what you deposited.


3. Mortgage Points Deduction

Mortgage points are upfront fees you may pay to lower your interest rate. In many cases, points count as prepaid interest and are deductible. IRS


When You Can Deduct Points Fully in the Purchase Year


You may deduct all points in the year you buy if:


  • The loan is for your primary residence,
  • Paying points is a normal practice in your area, and
  • You paid them directly at closing (not rolled into the loan). IRS


Otherwise, you usually spread the deduction over the loan life.


Example


You paid $6,000 in points on a $600,000 mortgage. If it meets IRS rules, you may deduct the full $6,000 this year.


4. Home Equity Loan or HELOC Interest

Home-equity interest is deductible only when the funds are used to buy, build, or substantially improve the home that secures the loan. IRS+1


Example


  • HELOC for a kitchen remodel → interest may be deductible.
  • HELOC to pay off credit cards or take a vacation → not deductible.


Keep receipts showing how the funds were used.


5. Energy Efficient Home Improvement Credit (IRC §25C)


This credit covers 30% of qualifying energy-efficient upgrades to an existing home — but 2025 is the last year to claim it under current law. IRS+2IRS+2


  • Eligible Improvements
  • Exterior windows/skylights
  • Exterior doors
  • Insulation and air sealing
  • Heat pumps and heat-pump water heaters
  • Certain high-efficiency HVAC and water heaters
  • Home energy audits IRS


Annual Caps (2025)


  • $1,200/year for most improvements
  • Windows/skylights: $600 cap
  • Doors: $250 per door, $500 total
  • Energy audits: $150 cap
  • $2,000/year for heat pumps, heat-pump water heaters, biomass stoves/boilers


Example

You install $5,000 in qualifying windows.
30% credit = $1,500, but window cap = $600 → your credit is $600.


6. Residential Clean Energy Credit

If you install renewable systems like solar, geothermal, wind, or battery storage, you can claim 30% of eligible costs, including labor. Like §25C, it currently expires after Dec 31, 2025. Clean Energy Resource Teams+2IRS+2


What Qualifies


  • Solar panels and solar water heating
  • Wind turbines
  • Geothermal heat pumps
  • Fuel cells (with special limits)
  • Battery storage paired with renewables Clean Energy Resource Teams


Example


A $20,000 solar install in 2025 → 30% credit = $6,000.


If the credit is larger than your tax bill, you can carry the extra forward to future years.


Note: IRS guidance in 2025 adds extra reporting for some equipment placed in service in 2025, so keep manufacturer paperwork. IRS


7. Mortgage Interest Credit (Mortgage Credit Certificate / MCC)


This is a lesser-known but valuable benefit for qualifying buyers. If your state or local housing agency issued you an MCC, you may claim a federal credit equal to a percentage of your mortgage interest.


Highlights

  • Credit rate is set by the certificate (often 10%–50%).
  • Max credit: $2,000/year.
  • Claimed on Form 8396 every year you hold the mortgage.


Who Usually Qualifies

Programs vary, but MCCs typically target:

  • First-time buyers
  • Buyers in “target areas”
  • Households under income and purchase-price limits
  • Owner-occupants with a new mortgage (not most refinances) LegalClarity


Important: If you sell within nine years, you might owe some recapture tax, depending on your gain and income. Accountably


8. Selling Your Home: Capital Gains Exclusion


When you sell a primary residence, you may exclude:


  • Up to $250,000 of gain (single)
  • Up to $500,000 of gain (married filing jointly) IRS


Basic Requirements


  • Owned the home 2 of the last 5 years
  • Lived in it as your main home 2 of the last 5 years
  • Generally can use the exclusion once every two years IRS


Example

Buy at $300,000, sell at $550,000 → gain $250,000.
If you meet the rules, you can potentially exclude the entire gain.


Pro move: Keep receipts for major improvements. They raise your “cost basis,” reducing taxable gain if you exceed the exclusion.


State and Local Incentives

Many states stack extra perks on top of federal rules — especially for renewable energy or efficiency upgrades. These can include rebates, property-tax exclusions, or local credits. Check your state energy office or city/county programs for current offerings. IRS


Timing & Compliance Tips

Watch the Calendar

Because §25C and §25D credits expire after December 31, 2025, upgrades need to be placed in service by that date to qualify. If you’re on the fence about energy improvements, 2025 is the “now or never” window.


Keep These Documents

  • Form 1098 (mortgage interest + escrowed taxes)
  • Property tax bills + payment proof
  • Closing disclosures showing deductible points
  • Receipts/invoices for all improvements
  • Manufacturer certifications for §25C items
  • Form 5695 for energy credits
  • MCC + Form 8396 if applicable


Good records = easier filing and safer audits.


Quick FAQ

What can a homeowner write off on taxes?
Mortgage interest, property taxes (subject to SALT limits), mortgage points, and some home-equity interest if used for home improvements. Credits may apply for energy upgrades or renewables.


Can I deduct home improvements?
Most improvements aren’t deductible right away, but they can increase your basis and lower capital gains later. Certain energy upgrades qualify for credits through 2025.


Are closing costs deductible?
Usually no — except certain items like mortgage points and property taxes paid at closing (if itemizing).


Do I automatically get a refund when I buy a home?
Not automatically. Buying a home can lower taxes, but whether you get a refund depends on your income, withholding, and total deductions/credits.


Bottom Line

Homeownership comes with real tax advantages — especially if you itemize or make qualifying energy upgrades. The biggest wins for most homeowners are mortgage interest and property taxes, while 2025 offers a last-chance opportunity for federal clean-energy credits. Pair that with smart documentation and timing, and your home can pay you back at tax time.

The passage of the One Big Beautiful Bill Act (OBBBA) has reshaped the tax landscape in a big way. Many tax cuts that were set to expire at the end of 2025 are now permanent, and several new planning opportunities have opened up. With the year quickly coming to a close, now is the ideal time to review your tax situation and see what steps you can take to reduce your 2025 tax bill. Before making any moves, work with your professional advisors to estimate what you’ll owe this year and identify which strategies best fit your situation. The earlier you begin, the more flexibility you’ll have to put these plans in motion before December 31. 1. Establish Your Tax Baseline Start by having your tax advisor prepare a pro forma 2025 tax return. This gives you a clear picture of where you stand—your projected income, deductions, and how different decisions may affect your final tax bill. If you're working with a financial team, request a year-to-date tax summary of your investment accounts. With this snapshot, you’ll have a solid foundation for determining which strategies are worth implementing before year-end. 2. Evaluate These Tax-Smart Strategies Harvest Tax Losses Markets have generally performed well this year, so you may be sitting on more taxable gains than expected. Tax-loss harvesting can help offset these gains by selling investments at a loss before year-end. If you want to repurchase the same investment, be sure to avoid the wash sale rule , which disallows a loss if you buy a substantially identical security within 30 days before or after the sale. One workaround is to double up —buy more now, wait 30+ days, then sell the original losing position. Important date: November 28, 2025 (the day after Thanksgiving) is the final day to sell at a loss and have it count for the 2025 tax year. Loss harvesting isn’t just a year-end task. Even in strong markets, individual positions may decline, creating opportunities throughout the year. Maximize Charitable Contribution Deductions If you plan to make charitable gifts, timing matters. Transfers of stock or other assets can take time to complete, so check with your financial institutions to ensure the donation is finalized before December 31. Because OBBBA imposes new charitable deduction limitations starting in 2026 , it may be advantageous to front-load charitable giving in 2025 . Beginning in 2026: Itemized charitable deductions are reduced by 0.5% of AGI Total itemized deductions for taxpayers in the 37% bracket are capped at 35% of AGI For high-income taxpayers, that may make a 2025 donation more valuable than the same gift in 2026. If you’re undecided about which charity to support, consider a donor-advised fund (DAF) . You receive the deduction immediately, but you can distribute the funds to charities later. Optimize Estimated Tax Payments Many high-income taxpayers must make quarterly estimated tax payments to avoid underpayment penalties. You can meet the requirements using the “lesser of” safe harbor : 110% of your prior year’s tax liability, or 90% of your current year’s projected tax liability If you expect your 2025 taxes to be significantly higher than in 2024, it may be strategic to base your estimates on 2024’s lower liability and invest the difference in short-term, principal-protected fixed-income investments. This lets you earn some return on money you’ll eventually pay in taxes. 3. Optimize Retirement, Compensation, and Benefits Max Out Retirement Contributions For 2025, the contribution limits are: IRAs: $7,000 (or $8,000 if age 50+) 401(k)/403(b): $23,500 $31,000 for those age 50+ $34,750 for those turning age 60–63 in 2025 If you’re eligible, consider whether a Roth conversion makes sense—especially if you expect higher income tax rates in the future and can pay the conversion tax using funds outside the IRA. Take Required Minimum Distributions (RMDs) Anyone age 73 or older generally must take RMDs by December 31 each year. If charity is part of your plan, a qualified charitable distribution (QCD) from your IRA can satisfy part or all of your RMD. This strategy, however, may not always be the most tax-efficient depending on your broader financial picture. For inherited IRAs where the owner died after 2019, new regulations beginning in 2025 require many beneficiaries to take annual distributions over a 10-year period , with the remaining balance distributed in year 10. The rules are complex, so work closely with your tax advisor. Consider Deferring Compensation If your employer offers a deferred compensation plan, election deadlines typically fall before December 31, 2025 for 2026 income deferrals. Deferring compensation delays income taxation until you receive the funds, potentially allowing you to take advantage of future lower tax rates. However, deferred compensation is subject to employer credit risk, so weigh the pros and cons carefully. Review Stock Options Executives with stock options may want to consider exercising some in 2025. Strong candidates for exercise include options that are: Deep in the money On high-dividend stocks Close to expiration Your advisory team can prepare an options breakeven analysis to help you decide. 4. Make Tax-Efficient Gifts to Family Use Lifetime Exclusion While It Lasts The current gift and estate tax exclusion is: $13.99 million per individual $27.98 million per married couple These increase to $15 million ($30 million for couples) in 2026 under OBBBA. If you anticipate a taxable estate and have unused exemption, making large gifts now may help lock in additional tax-free transfer capacity. Take Advantage of the Annual Gift Exclusion For 2025, you may give: $19,000 per recipient (individual) $38,000 per recipient (married couple electing to split gifts) This exclusion is use-it-or-lose-it —unused amounts cannot be carried over to future years. Many families use this strategy to fund 529 education plans , where earnings grow tax-free when used for qualified education expenses. 5.

It’s a question that can send a shiver down your spine, a classic nail-biter that pops up right around tax season: “How much do I really owe the IRS?” Let’s be honest, navigating the world of taxes can feel like trying to solve a Rubik’s Cube in the dark. Whether you’ve hit a few financial bumps in the road or simply lost track of your tax returns, figuring out your standing with the Internal Revenue Service (IRS) is the first crucial step toward getting your financial house in order. This guide will walk you through the different ways to uncover that magic number, from sleuthing online to making a good old-fashioned phone call. And once you know what you’re up against, we’ll even explore some expert-backed strategies for settling your score with Uncle Sam. Cracking the Code: How to Figure Out What You Owe Finding out your tax liability is easier than you might think. The IRS has several methods available to help you get the information you need. Here’s a breakdown of your options: Your Online IRS Account The quickest and most convenient way to get to the bottom of your tax situation is by using the IRS’s online tools. The “View Your Tax Account” feature on the IRS website is your one-stop shop for all things tax-related. To get started, you’ll need to create an account and verify your identity. You’ll need some personal information on hand, like your Social Security number, date of birth, and the filing status and mailing address from your most recent tax return. Once you’re in, you’ll have access to a wealth of information, including: Your payment history Any outstanding balances you owe Information about your payment plans Digital copies of certain IRS notices This is the fastest way to see what you owe and even make payments online. Just be mindful of any potential bank fees associated with online payments. A Little Help From a Friend: Calling the IRS If you prefer a more personal touch, you can always give the IRS a call. The general inquiry line is 1-800-829-1040. Before you dial, make sure you have your personal information and a copy of your most recent tax return handy. An IRS representative can help you with a balance inquiry, explain any outstanding balances, and walk you through your payment options. While it might take a bit of patience to get through, speaking with a real person can be incredibly helpful, especially if you have questions about your tax records or payment plans. The Paper Trail: Reaching Out by Mail For those who appreciate the tangible nature of snail mail, you can also request your tax information by mail. You’ll need to send a written request to the IRS, and it’s a good idea to use the address listed on the most recent notice you’ve received. If you don’t have a recent notice, you can find the correct address on the IRS website. Keep in mind that this is the slowest method, and with taxes, time is of the essence. Unpaid taxes can quickly accumulate penalties and interest, so it’s best to use a faster method if possible. You’ve Got the Number, Now What? Strategies for Settling Your Tax Bill Knowing how much you owe is half the battle. Now it’s time to come up with a plan to pay it off. Here are some effective strategies for settling your tax bill: File on Time, Every Time: The easiest way to avoid getting into tax trouble is to file your taxes on time, every year. This will help you avoid late filing penalties. Explore Payment Options: If you can’t pay your entire tax bill at once, don’t panic. The IRS offers several payment options, including installment agreements and offers in compromise. You can apply for these online or with the help of an IRS representative. Use Your Refund to Your Advantage: If you’re expecting a tax refund, you can have the IRS apply it directly to your outstanding balance. Look into Penalty Waivers: If you have a good compliance history, you may be eligible for a first-time penalty waiver. It’s worth looking into! Don’t Be Afraid to Ask for Help: If you’re feeling overwhelmed, consider seeking advice from a tax professional. They can help you navigate the complexities of the tax system and find the best solution for your unique situation. Frequently Asked Questions How long does the IRS have to collect unpaid taxes? The IRS generally has 10 years to collect unpaid taxes from the date they were assessed. This is known as the Collection Statute Expiration Date (CSED). However, certain actions, like entering into an installment agreement or filing for bankruptcy, can extend this period. Should I take out a loan to pay my taxes? This is a tricky one. While a loan can provide immediate relief and help you avoid IRS penalties and interest, it’s not without its own risks. You’ll need to be sure you can afford the loan repayments, and you’ll want to compare the interest rate on the loan to the penalties and interest charged by the IRS. It’s always a good idea to consult with a financial advisor before making this decision. How can I check my IRS balance myself? As we’ve covered, you have three main options: online through the “View Your Tax Account” feature on the IRS website, by phone at 1-800-829-1040, or by mail. For the fastest and most comprehensive information, the online portal is your best bet. Dealing with the IRS can be stressful, but it doesn’t have to be a nightmare. By taking a proactive approach and using the resources available to you, you can take control of your tax situation and get back on the path to financial freedom. You don’t have to face the IRS alone.  Contact Arch Tax today and we’ll help you understand your options and take the next step s forward .

Every year, as tax season begins, millions of Americans diligently gather their documents, determined to file accurately and on time. Yet many unwittingly fall into procedural traps—set not by malice, but by the sheer complexity of the U.S. tax code. From the perspective of a tax resolution company who’s seen countless taxpayers blindsided by unexpected notices and penalties, it’s clear the IRS has a playbook. Automated systems, targeted audits, and strict procedural rules can catch even the most honest individuals off guard. This isn’t about scare tactics—it’s about awareness. Understanding where these traps lie is the first step toward navigating tax season with confidence. Below are five of the most common IRS traps, along with practical steps to help you steer clear. Trap #1: The Automated Refund Delay Trap What It Is: The IRS withholds refunds from millions of taxpayers for “additional review,” a process triggered automatically by sophisticated error-detection algorithms. While most refunds are issued within 21 days, a flagged return can be delayed for months with little communication. Why It’s a Trap: Even minor mismatches between your reported income and what the IRS receives from employers (W-2s) or clients (1099s) can freeze your refund. Common triggers include small data entry errors, incorrect Social Security numbers, or deductions that look statistically unusual for your income level. How to Avoid It: Cross-check every figure on your return before filing. E-file early—late-season filers face heavier scrutiny—and always use direct deposit. A paper check is over 16 times more likely to be lost or stolen, which can prolong the wait even further. Trap #2: The High-Stakes Credit Crackdown (EITC & CTC) What It Is: The IRS aggressively audits returns claiming the Earned Income Tax Credit (EITC) and Child Tax Credit (CTC) . These credits are vital for working families, yet have some of the highest error rates in the system. Why It’s a Trap: Because of those error rates, the IRS effectively operates on a “prove you’re right” basis. EITC claims are audited more than four times as often as typical individual returns—and certain demographics face disproportionate scrutiny. How to Avoid It: Be audit-ready from day one. Keep: Proof of income (pay stubs, 1099s, bank statements) Proof of residency for dependents (school, medical, or official records) Don’t file until all documentation is organized. If audited, clear proof can quickly resolve the issue in your favor. Trap #3: The Gig Economy Reporting Trap (1099-K) What It Is: Third-party payment apps like PayPal, Venmo, and Cash App now report income for goods and services through Form 1099-K. Though the threshold has changed repeatedly, the reporting system remains firmly in place. Why It’s a Trap: Many gig workers and side-hustlers assume small amounts of income “don’t count.” The IRS’s automated matching software disagrees—discrepancies between what platforms report and what you file are automatically flagged. How to Avoid It: Report all income, even if you don’t receive a 1099-K. Track deductible business expenses carefully—mileage, phone, supplies, and other legitimate costs—to reduce taxable income. Always keep receipts and logs to substantiate your claims. Trap #4: The “Voluntary” Disclosure Illusion What It Is: Sometimes the IRS sends friendly-sounding letters encouraging taxpayers to “voluntarily” correct past filings or unpaid balances. Why It’s a Trap: The IRS generally has 10 years from the date a tax is assessed to collect it—known as the Collection Statute Expiration Date (CSED) . When you respond to these letters, file old returns, or make payments, you can accidentally restart or extend that 10-year clock—giving the IRS more time to pursue you with added penalties and interest. How to Avoid It: Never reply to an old-debt notice without professional advice. A tax resolution expert can determine your CSED and guide you on whether to respond strategically—or not at all. Trap #5: The Resolution Runaround (Offer in Compromise) What It Is: The IRS Fresh Start Program , especially the Offer in Compromise (OIC) , is promoted as a chance to settle tax debt for less than you owe. Why It’s a Trap: OIC qualification rules are deliberately strict, and only about 20–40% of applications are approved. Many taxpayers apply without understanding the IRS’s complex financial formulas or fail to provide every required document. Rejection not only wastes time and money but also hands the IRS your complete financial profile. How to Avoid It: Before applying, get a realistic assessment of your eligibility. Tools like Arch Tax’s Resolution Assistant can show which programs you actually qualify for and save you from unnecessary exposure. Conclusion: Navigating the Maze with Confidence The IRS doesn’t have to deceive taxpayers—the system itself is complicated enough to trap the unprepared. Awareness, documentation, and expert guidance are your strongest defenses. At Arch Tax , we help taxpayers navigate the complexities before they turn into costly problems.

Most people are surprised to learn that the IRS doesn’t have forever to collect on back taxes. In general, the agency has a 10-year statute of limitations that starts the day your tax debt is officially assessed. Once that clock runs out, the IRS typically loses its ability to collect. Sounds straightforward, right? Not so fast. There are important exceptions that can pause or even extend that 10-year collection window—and if you’re not aware of them, you might think you’re in the clear when you’re not. At Arch Tax, we believe in helping our clients understand how these rules really work so you can make smart, informed decisions about your situation.
