The 2027 mortgage interest tax deduction can provide a valuable federal tax benefit for eligible homeowners.
Homeowners may generally deduct qualifying interest paid on mortgage debt secured by their main home or a qualifying second home when they itemize deductions.
The mortgage interest deduction depends on several factors, including when the mortgage was taken out, the amount of qualifying mortgage debt, how loan proceeds were used, and whether the taxpayer chooses to itemize deductions.

Is Mortgage Interest Tax Deductible in 2027?
Yes, qualifying mortgage interest can generally be deductible in 2027.
However, homeowners cannot automatically deduct every dollar of interest they pay. The mortgage must meet federal requirements, and the taxpayer generally must itemize deductions rather than take the standard deduction.

For many homeowners, the first question is whether their total itemized deductions exceed the standard deduction.
2027 Mortgage Interest Deduction Limits
For qualifying home acquisition debt incurred after December 15, 2017, the general mortgage debt limits are:
Filing Status
Mortgage Debt Limit
Single
$750,000
Married Filing Jointly
$750,000
Married Filing Separately
$375,000
These limits generally apply to qualifying mortgage debt on a taxpayer’s main home and second home.
Certain older mortgages can qualify for the higher $1 million limit.
The $750,000 Mortgage Interest Limit
The $750,000 limit is important for homeowners with larger mortgages.
For qualifying newer mortgage debt, homeowners generally can deduct interest attributable to up to $750,000 of qualifying debt.
Example: A married couple has a $600,000 qualifying mortgage and pays $30,000 in mortgage interest during 2027. Because the mortgage is below the $750,000 limit, the couple may be able to deduct the full $30,000 if all other requirements are met and they itemize.
What If Your Mortgage Is More Than $750,000?
A mortgage larger than $750,000 does not mean that none of the interest is deductible.
Generally, the deduction is limited to the interest attributable to the portion of qualifying mortgage debt within the applicable limit.
Example: A homeowner has a $1 million mortgage that is subject to the $750,000 limit. The homeowner may be able to deduct interest attributable to $750,000 of qualifying debt rather than all of the interest paid on the $1 million mortgage.
The exact calculation can be more complicated when multiple mortgages are involved.
Older Mortgages Can Qualify for a $1 Million Limit
Certain qualifying mortgage debt incurred before December 16, 2017, can be subject to the older $1 million limit.
For married taxpayers filing separately, the corresponding limit is generally $500,000.
This makes the date a mortgage was incurred particularly important when calculating the mortgage interest deduction.
2027 Mortgage Interest Deduction for Married Couples
Married couples filing jointly generally have a $750,000 limit for qualifying new acquisition debt.
The couple does not receive a separate $750,000 limit for each spouse.
Example: A married couple has a $500,000 mortgage on its main home and a $300,000 mortgage on a qualifying second home.
The combined mortgage debt is $800,000, so the couple may need to calculate its deductible interest based on the applicable $750,000 limit.
Married Filing Separately
The mortgage debt limit is generally $375,000 for married taxpayers filing separately when the applicable mortgage debt was incurred after December 15, 2017.
For qualifying older mortgage debt, the limit can generally be $500,000.
Couples should compare the tax consequences of filing jointly and separately before selecting a filing status.
Do You Have to Itemize to Deduct Mortgage Interest?
Generally, yes.
The federal mortgage interest deduction is generally an itemized deduction.
Homeowners who take the standard deduction generally cannot separately add mortgage interest to it.
Standard Deduction vs. Mortgage Interest
Having a mortgage does not automatically mean that itemizing deductions will save money.
Homeowners should total their potential itemized deductions and compare that amount with the standard deduction available for their filing status.
Example: A married couple has $15,000 of mortgage interest, $5,000 of other allowable itemized deductions, and no significant additional deductions.
If the couple’s total itemized deductions are less than their available standard deduction, taking the standard deduction may provide the larger tax benefit.
What Is Qualifying Mortgage Interest?
Qualifying mortgage interest generally includes interest paid on debt secured by a qualified home.
The loan can be used to purchase, construct, or substantially improve the home, subject to the applicable federal requirements.
The property generally needs to be the taxpayer’s main home or a qualifying second home.
Mortgage Interest on a Primary Residence
Interest paid on a mortgage secured by your primary residence can generally qualify when the applicable requirements are satisfied.
A qualified home can include several types of residential property.
Examples include:
Single-family homes
Condominiums
Cooperative apartments
Mobile homes
House trailers
Certain houseboats
Mortgage Interest on a Second Home
Mortgage interest on a qualifying second home may also be deductible.
A second home could be a vacation house, lake home, condominium, or other qualifying residence.
The mortgage debt on the main home and second home generally must be considered together when applying the mortgage debt limitations.
Can I Deduct Mortgage Interest on a Vacation Home?
Potentially.
A vacation property may qualify as a second home if it meets the federal requirements.
If you rent the property to others, additional rules can apply depending on how often you use the property personally and how often it is rented.
Mortgage Interest on a Rental Property
Mortgage interest on a rental property can be treated differently than interest on a personal residence.
Qualifying interest associated with a rental property is generally treated as a rental expense rather than a personal itemized deduction.
Homeowners who rent out a property should keep separate records for rental and personal expenses.
Home Equity Loan Interest in 2027
Interest on a home equity loan can potentially qualify for the mortgage interest deduction.
However, the use of the borrowed money is extremely important.
For newer home equity debt, the proceeds generally must be used to buy, build, or substantially improve the home securing the loan.
HELOC Interest Deduction
A home equity line of credit, or HELOC, can also potentially generate deductible mortgage interest.
Example: A homeowner takes out a $100,000 HELOC and uses the money to build a major addition to the home. The interest may potentially qualify for the mortgage interest deduction, subject to the applicable requirements and debt limits.
HELOC Used to Pay Credit Cards
Using a HELOC to pay personal debts generally does not make the interest deductible.
Example: A homeowner borrows $50,000 through a HELOC and uses the money to pay credit card balances. The interest on that portion generally does not qualify as deductible home mortgage interest.
This is an important consideration for homeowners considering using home equity for debt consolidation.
Mortgage Interest and Home Improvements
Interest on qualifying debt used to substantially improve a home may be deductible.
Examples of substantial improvements can include:
Building a home addition
Adding a bathroom
Major kitchen remodeling
Replacing a roof
Adding a permanent structure
Major structural renovations
Routine personal expenses generally do not qualify.
Mortgage Refinancing and the 2027 Deduction
Refinancing a mortgage does not automatically eliminate the mortgage interest deduction.
However, the amount and use of the refinanced debt can affect how much interest qualifies.
Generally, refinanced debt can retain acquisition-debt treatment to the extent it replaces qualifying acquisition debt, subject to applicable rules.
Example: A homeowner has a $300,000 qualifying mortgage and refinances it into a $400,000 mortgage. The homeowner uses the additional $100,000 to pay credit cards and other personal expenses.
Interest on the additional personal-use debt generally does not qualify as deductible home mortgage interest.
If the additional funds were used to substantially improve the home, the tax treatment could be different.
Mortgage Points in 2027
Certain mortgage points can also qualify for a federal deduction.
Points are certain charges paid to obtain a mortgage.
Depending on the circumstances, qualifying points paid when purchasing a primary residence may be deductible in the year paid.
Other points may need to be deducted over the life of the mortgage.
Points Paid When Refinancing
Points paid when refinancing generally receive different tax treatment.
They generally must be deducted over the term of the new mortgage.
Special rules can apply if some of the refinance proceeds are used for qualifying home improvements.
Mortgage Insurance Deduction
Homeowners should not automatically assume that private mortgage insurance premiums are deductible as mortgage interest.
The federal itemized deduction for mortgage insurance premiums has expired under current rules.
Mortgage insurance and mortgage interest are separate expenses.
Mortgage Interest and Property Taxes
Mortgage interest and property taxes are separate deductions.
Mortgage interest is generally claimed as qualifying home mortgage interest when the taxpayer itemizes.
Property taxes are generally subject to separate rules governing state and local tax deductions.
A homeowner may potentially claim both when eligible.
Mortgage Interest and the SALT Deduction
The state and local tax deduction, commonly called the SALT deduction, is separate from the mortgage interest deduction.
Property taxes can be included in the SALT calculation when eligible.
Mortgage interest is not part of the SALT deduction.
Mortgage Interest Deduction for Seniors
Seniors can generally claim qualifying mortgage interest under the same basic rules that apply to other homeowners.
Being age 65 or older does not eliminate the mortgage interest deduction.
However, seniors should compare itemized deductions with the standard deduction while considering any additional deductions available to older taxpayers.
Mortgage Interest and Retirement Income
Retirees often have several different sources of income.
These may include:
Social Security
Pensions
Traditional IRAs
401(k) plans
Investment accounts
Part-time employment
Qualifying mortgage interest can potentially reduce taxable income when the retiree itemizes.
Mortgage Interest and Social Security
Mortgage interest does not directly reduce Social Security benefits.
However, a qualifying itemized deduction can reduce taxable income.
For retirees who receive taxable Social Security benefits, mortgage interest may therefore affect the overall federal tax calculation.
Mortgage Interest and IRA Withdrawals
Traditional IRA distributions are generally taxable.
A retiree who itemizes can potentially use qualifying mortgage interest and other deductions to reduce taxable income.
The mortgage interest deduction does not make a traditional IRA distribution tax-free.
Mortgage Interest and 401(k) Distributions
Taxable 401(k) distributions are generally included in taxable income.
A qualifying mortgage interest deduction can reduce taxable income if the taxpayer itemizes.
It does not eliminate the tax on the retirement distribution.
Mortgage Interest and Capital Gains
Mortgage interest is generally an itemized deduction.
Long-term capital gains are generally taxed under separate federal rules.
Homeowners with investment income should consider both their deductions and investment gains when estimating their overall tax liability.
Form 1098 Mortgage Interest Statement
Mortgage lenders generally provide Form 1098 to report mortgage interest paid during the year.
Homeowners should review Form 1098 carefully.
The amount shown on the form may not always equal the final amount deductible if mortgage debt limitations or other special rules apply.
Where Do You Claim Mortgage Interest?
Qualifying mortgage interest is generally reported on Schedule A when the taxpayer itemizes deductions.
Homeowners with multiple mortgages, refinancing, HELOCs, rental properties, or mixed-use properties may need additional calculations.
Mortgage Records to Keep
Homeowners should maintain important mortgage records.
These can include:
Form 1098
Mortgage statements
Closing documents
Refinancing paperwork
HELOC statements
Home equity loan documents
Records of major improvements
Documentation showing how loan proceeds were used
Good records can make it easier to calculate the correct deduction.
Common Mortgage Interest Deduction Mistakes
Homeowners frequently make mistakes when calculating their deduction.
Common errors include:
Assuming all mortgage interest is deductible
Claiming mortgage interest while taking the standard deduction
Ignoring mortgage debt limits
Deducting HELOC interest used for personal expenses
Forgetting about a second mortgage
Treating property taxes as mortgage interest
Assuming mortgage insurance is deductible
Failing to keep Form 1098
Treating rental property interest as personal mortgage interest
Is Mortgage Interest a Tax Credit?
No.
Mortgage interest is generally a tax deduction, not a tax credit.
A deduction reduces taxable income.
A tax credit directly reduces the amount of tax owed.
Example: A $20,000 mortgage interest deduction does not mean the homeowner receives $20,000 from the IRS. If the deduction reduces taxable income by $20,000, the actual tax savings depend on the taxpayer’s marginal tax rate and complete tax situation.
How Much Can Mortgage Interest Save You?
The value of the mortgage interest deduction depends on your tax bracket and whether you benefit from itemizing.
Example: A homeowner has $20,000 of qualifying deductible mortgage interest and is in the 22% marginal tax bracket.
A simplified calculation is:
$20,000 × 22% = $4,400
The potential federal income tax savings could be approximately $4,400.
Actual savings can vary depending on the homeowner’s complete tax return.
Is Mortgage Interest Still a Good Tax Deduction?
For homeowners with substantial qualifying mortgage interest and other itemized deductions, the deduction can still provide a significant tax benefit.
For homeowners with smaller mortgages, the standard deduction may be more valuable.
The best choice depends on the taxpayer’s filing status, income, mortgage interest, and other deductions.
2027 Mortgage Interest Deduction Example
Suppose a married couple filing jointly has:
$25,000 mortgage interest
$10,000 qualifying state and local taxes
$8,000 charitable contributions
The couple has $43,000 of potential itemized deductions before considering any other applicable deductions or limitations.
If their itemized deductions exceed their available standard deduction, itemizing may provide a greater federal tax benefit.
Mortgage Interest for a New Home
New homeowners should save their closing documents and mortgage paperwork.
The first year of ownership can include mortgage interest, points, prepaid interest, property taxes, and other costs.
Not every closing expense is deductible, so homeowners should distinguish qualifying mortgage interest from other home-buying costs.
Mortgage Interest and Home Selling
Mortgage interest paid before selling a home can potentially qualify for a deduction when the applicable requirements are met.
Homeowners should also maintain records of major improvements because qualifying improvements can affect the home’s tax basis when it is sold.
2027 Mortgage Interest Tax Planning
Homeowners should review their mortgage and tax situation before the end of the year.
Important questions include:
How much mortgage interest did I pay?
Is my mortgage below the applicable debt limit?
Do I have a HELOC?
How did I use my home equity loan proceeds?
Do I own a second home?
Am I better off itemizing or taking the standard deduction?
Homeowners should have their Form 1098, mortgage statements, property tax records, charitable contribution records, and other tax documents available when preparing their 2027 federal tax return.
