Introduction: What is Publication 530?
IRS Publication 530, officially titled Tax Information for Homeowners, is the federal government’s primary tax guide for residential property owners. For millions of Americans, buying a home represents both their largest personal investment and a cornerstone of their long-term financial security. To support homeownership, the Internal Revenue Code provides significant tax benefits, but it also imposes strict limits on what can be deducted.
The primary purpose of Publication 530 is to explain how homeowners should treat housing-related expenses on their federal income tax returns. It details which expenses can be deducted annually on Schedule A, which settlement fees can be added to your home’s cost basis, and which everyday housing costs are strictly non-deductible personal living expenses.
Because major tax reforms changed mortgage debt caps and property tax deduction limits, understanding Publication 530 is critical for every property owner. Whether you are buying your first home, refinancing an existing mortgage, or making energy-efficient home renovations, this guide helps you claim all eligible tax breaks while keeping your tax records fully compliant.

Detailed Breakdown of Main Concepts
1. Home Mortgage Interest Deductions
Under federal tax law, you can deduct the interest you pay on a loan secured by a qualified home (your primary residence and one designated second home). However, the debt must be “acquisition indebtedness”—meaning the loan was used to buy, build, or substantially improve the home securing the mortgage.
Publication 530 outlines statutory mortgage debt limits established by tax reform. For mortgages originated after December 15, 2017, you can only deduct interest on up to $750,000 of qualifying home debt ($375,000 if Married Filing Separately). Older loans originated on or before that date are grandfathered under a higher $1,000,000 debt limit ($500,000 for married filing separately). Interest on home equity loans or lines of credit (HELOCs) is deductible only if the borrowed funds were used to substantially improve the home.
2. Real Estate Property Taxes and the SALT Cap
State and local real estate taxes levied for the general public welfare are deductible on Schedule A. However, Publication 530 highlights the State and Local Tax (SALT) deduction limit, which caps your total combined deduction for property taxes and state income (or sales) taxes at $10,000 per year ($5,000 for married individuals filing separately).
Publication 530 also addresses mortgage escrow accounts. If your monthly mortgage payment includes an escrow contribution for property taxes, you cannot deduct the money when it enters the escrow account. You can only deduct real estate taxes in the calendar year the mortgage servicer actually disburses the payment to the local taxing authority.
3. Deducting Loan Points (Prepaid Interest)
“Points” describe charges paid by a borrower to obtain a mortgage, often referred to as loan origination fees, maximum loan charges, or discount points. One point equals 1% of the total loan amount. Because points represent prepaid interest, they are generally deductible as mortgage interest.
When purchasing a primary home, you can deduct points in full in the year you pay them if you meet specific IRS criteria (such as using unborrowed funds at closing and points being customary in your geographic area). However, points paid to refinance an existing mortgage generally cannot be deducted all at once. Instead, refinance points must be amortized and deducted evenly over the entire life of the new loan.
4. Settlement and Closing Costs: What Counts?
When you purchase a home, your closing disclosure lists dozens of individual line items and fees. Publication 530 divides these closing costs into three distinct tax categories:
- Immediately Deductible: Prepaid mortgage interest and qualifying loan discount points.
- Added to Basis: Fees that increase your cost basis, including title search fees, owner’s title insurance, legal fees, recording fees, and transfer taxes paid by the buyer.
- Non-Deductible: Personal loan charges that neither provide a deduction nor increase basis, such as appraisal fees, credit report fees, and homeowners insurance premiums.
5. Tracking Adjusted Basis and Home Improvements
Your home’s “adjusted basis” is the total investment you have in the property for federal tax purposes. Basis starts with your original purchase contract price plus qualifying settlement fees paid at closing. Over time, you increase your basis by adding the cost of capital improvements.
Publication 530 distinguishes between capital improvements and routine maintenance. Capital improvements add value to the property, prolong its useful life, or adapt it to new uses (such as a new roof, upgraded electrical wiring, a remodeled kitchen, or an addition). Routine repairs—like repainting a wall, servicing an air conditioner, or repairing a leaky faucet—are non-deductible personal maintenance costs that do not increase basis.
6. Residential Clean Energy and Home Improvement Credits
Homeowners who invest in energy efficiency can claim valuable federal tax credits. Unlike deductions that reduce taxable income, credits reduce your final tax bill dollar-for-dollar.
Publication 530 covers two major credits: the Energy Efficient Home Improvement Credit (covering exterior doors, windows, insulation, and high-efficiency heat pumps) and the Residential Clean Energy Credit. The clean energy credit provides a 30% tax credit on the full cost of installing solar electric panels, solar water heaters, geothermal heat pumps, small wind energy systems, and battery storage technology.
Practical Examples and Scenarios
The following examples demonstrate how homeowners apply the rules in Publication 530 to real-world housing situations.
Scenario 1: Amortizing Points on a Refinanced Mortgage
David refinances his primary residence to secure a lower interest rate, taking out a new 30-year mortgage for $300,000. To lower his interest rate further, David pays 1 point ($3,000) at closing from his personal savings account.
Because the transaction is a refinance rather than an original home purchase, David cannot deduct the $3,000 in full on his current-year tax return. Following Publication 530, David must amortize the points over the 360-month life of the loan. He deducts $100 per year ($3,000 / 30 years) as mortgage interest on Schedule A for each year the loan remains active.
Scenario 2: Using a Home Equity Line of Credit (HELOC)
Elena and Marcus take out a $50,000 Home Equity Line of Credit secured by their primary home. They use $35,000 of the funds to completely gut and remodel their outdated kitchen, and they use the remaining $15,000 to pay off credit card balances.
Under Publication 530, only debt used to buy, build, or substantially improve the home qualifies for the mortgage interest deduction. Elena and Marcus can deduct the interest paid on the $35,000 portion used for the kitchen remodel on Schedule A. The interest paid on the $15,000 used for personal debts is strictly non-deductible.

How This Publication Relates to Specific Forms
Publication 530 provides the regulatory guidelines needed to complete several core federal tax documents:
- Schedule A (Form 1040): The primary schedule for itemized deductions, where real estate taxes are reported on Line 5b and deductible mortgage interest and points are reported on Lines 8a through 8c.
- Form 1098 (Mortgage Interest Statement): The annual tax document sent by your mortgage lender reporting total interest paid, deductible points, and property taxes disbursed from escrow.
- Form 5695 (Residential Energy Credits): Used to calculate and claim nonrefundable tax credits for installing energy-efficient doors, heat pumps, and solar systems.
- Form 8396 (Mortgage Interest Credit): Used by low-to-moderate-income buyers who were issued a Mortgage Credit Certificate (MCC) by a state or local government agency to claim a direct tax credit.
- Form 1040 (U.S. Individual Income Tax Return): The main tax return where homeowner tax deductions and energy credits reduce your taxable income and tax liability.
Common Misunderstandings Clarified
Misunderstanding 1: “Homeowners insurance and HOA dues are tax-deductible.”
Many homeowners believe that because homeowners insurance and homeowners association (HOA) dues are mandatory to live in their home, they are tax-deductible. The IRS treats insurance premiums and HOA fees as personal living expenses. They cannot be deducted on Schedule A and cannot be added to your home’s cost basis.
Misunderstanding 2: “All home equity loan interest is tax-deductible.”
Prior to tax reform, homeowners could deduct interest on up to $100,000 of home equity debt regardless of how the money was used. Under current law, interest on home equity loans and lines of credit is completely non-deductible if the funds are spent on personal items like vacations, car purchases, or college tuition. The money must be used to substantially improve the home that secures the loan.
Misunderstanding 3: “All points on a refinanced mortgage can be deducted in year one.”
Points paid on a refinance must be spread out evenly over the entire term of the loan. The only exception occurs if a portion of the refinanced loan proceeds is used to make substantial improvements to your primary home, in which case the points associated with the renovation portion can be deducted in year one.
Misunderstanding 4: “Property taxes are deductible as soon as you pay them into your escrow account.”
Paying money into a lender’s escrow account does not constitute a tax payment to the government. You can only deduct real estate taxes in the tax year that your mortgage servicer actually transfers the money out of escrow and pays the local county or municipal tax collector.
Why This Publication Matters for Taxpayers
A home is not just a residence; it is a major tax asset. Publication 530 helps homeowners accurately compare their itemized deductions against the standard deduction, ensuring they choose the strategy that saves them the most money each tax season.
Additionally, Publication 530 provides vital long-term protection. When you eventually sell your home years or decades down the road, you will need an accurate record of your adjusted basis to calculate capital gains. Understanding which closing costs and remodeling invoices increase basis today ensures you shield maximum home equity from taxes tomorrow.
Frequently Asked Questions
Can I deduct mortgage interest on a second home?
Yes. You can deduct mortgage interest on your primary residence plus one other qualified personal home (such as a vacation home), provided your combined mortgage debt on both properties does not exceed the statutory $750,000 cap ($1,000,000 for older loans).
Are local assessments for new neighborhood sidewalks or sewer mains deductible?
No. Local government assessments for local benefits that tend to increase the value of your property—such as paving a new road, building new sidewalks, or installing sewer lines—are not deductible as real estate taxes. Instead, you must add these assessments to your home’s cost basis.
What happens to unamortized refinance points if I pay off the mortgage early?
If you pay off your refinanced mortgage early (either by selling the home or refinancing with a different lender), you can deduct all remaining unamortized points in full in the year the loan is paid off.
Is Private Mortgage Insurance (PMI) currently tax-deductible?
Under current federal tax rules, the temporary legislative provision that allowed homeowners to deduct PMI premiums has expired. Unless Congress passes retroactive legislation renewing the provision, PMI is treated as non-deductible personal insurance.
Can I deduct transfer taxes paid when buying a home?
Transfer taxes and stamp fees paid when purchasing a home cannot be deducted on Schedule A. However, transfer taxes paid by the buyer are capitalized costs that are added directly to your home’s cost basis, helping lower future capital gains when you sell.
Conclusion
IRS Publication 530 is the definitive guide for understanding the tax advantages and responsibilities of homeownership. By establishing clear guidelines for the mortgage interest deduction, clarifying property tax rules, and explaining how closing costs and remodeling projects build your tax basis, it provides the tools needed to manage real estate assets wisely.
Whether you are closing on your first home, planning energy-efficient upgrades, or preparing your annual tax return, consulting Publication 530 ensures you claim every allowable deduction and build an audit-proof foundation for your home’s financial future.
