What Is the Mortgage Interest Deduction and How Much Can You Claim?
Quick Answer: For 2025, homeowners can deduct mortgage interest on loan balances up to $750,000 for mortgages taken out after December 15, 2017, or up to $1,000,000 for older mortgages, provided they itemize deductions on their tax return.
The mortgage interest deduction remains one of the most valuable tax breaks for homeowners, allowing you to reduce your taxable income by the amount of interest paid to your lender. This is distinct from the principal payment, which is not deductible.
How to Claim Your Mortgage Interest Deduction
To claim your mortgage interest deduction in 2025, you must meet several requirements. First, the loan must be secured by your home (primary residence or second home). Second, you must itemize your deductions instead of taking the standard deduction. Third, the mortgage balance cannot exceed the $750,000 limit for post-2017 mortgages.
Your mortgage lender provides a Form 1098 in early 2025 showing your mortgage interest paid. You then enter this amount on Line 8 of Schedule A (Form 1040) when filing your tax return. Include mortgage points paid in your first year of the loan, which are treated as prepaid interest.
Real-World Example: Calculating Your Deduction
Consider a married couple filing jointly who purchased a home in 2025 with a $500,000 mortgage at 6.5% interest. In their first year, they will pay approximately $32,500 in mortgage interest. Combined with their property taxes of $8,000 and other itemized deductions, they have total itemizable deductions of $48,000, which exceeds their standard deduction of $31,500 for 2025. By itemizing, they save $16,500 in taxable income.
Pro Tip: If you have a large mortgage balance, calculate whether itemizing deductions (including mortgage interest and property taxes) exceeds your standard deduction. For 2025, married couples have a $31,500 standard deduction, so if your itemized deductions exceed this amount, itemizing saves you money.
How Can You Deduct Property Taxes Up to $40,000 for 2025?
Quick Answer: The SALT deduction cap has been permanently increased to $40,000 for 2025 through 2028 under the One Big Beautiful Bill Act. This is one of the most significant changes to homeowner tax breaks for 2025, allowing high-tax state residents to deduct substantially more property taxes.
For decades, homeowners in high-tax states like California, New York, and New Jersey struggled with the $10,000 state and local tax (SALT) deduction cap. In 2025, OBBBA permanently increased this limit to $40,000, providing major relief for homeowners in these regions while offering an opportunity to significantly reduce taxable income.
Understanding the New $40,000 SALT Cap
The $40,000 SALT deduction includes combined state and local income taxes, sales taxes, and property taxes. You can deduct the highest amount on your state return and local property taxes, but not both income taxes and sales taxes. Most homeowners benefit by deducting property taxes and state income taxes separately.
However, the OBBBA included income-based phase-out provisions. For 2025, the phase-out begins at higher income thresholds, providing full relief to most middle and upper-income earners. Real estate investors and high-net-worth individuals should verify their phase-out status with a tax professional.
| Tax Category | 2025 Deductible Amount | Notes |
|---|---|---|
| Property Taxes | Up to $40,000 (combined) | Real and personal property taxes |
| State Income Tax | Up to $40,000 (combined) | Can combine with property taxes |
| Sales Tax | Up to $40,000 (combined) | Choose either income or sales tax |
| Total SALT Limit | $40,000 maximum | Through 2028; may change in 2029 |
Real Estate Investor Strategy: Prepayment Tactics
Real estate investors in high-tax states can maximize their SALT deduction by considering prepayment strategies. If your jurisdiction allows, you can prepay your Q1 2026 property taxes before December 31, 2025. This front-loads the deduction into the current tax year, potentially pushing you into itemization status and maximizing your 2025 deductions.
Did You Know? The $40,000 SALT deduction cap is permanent through 2028 under OBBBA. This provides certainty for real estate investors planning long-term tax strategies for rental property portfolios.
What Energy-Efficient Home Improvements Qualify for 2025 Tax Credits?
Quick Answer: For 2025, homeowners can claim tax credits for energy improvements including a 30% credit for solar/renewable systems and a 10% credit for insulation, windows, and roofing, plus a flat $50-$300 credit for Energy Star-certified equipment. These credits expire after 2025, making 2025 your last year to claim them.
Energy-efficient home improvements offer some of the most generous tax breaks for homeowners in 2025. Unlike deductions, credits directly reduce your tax liability dollar-for-dollar. This means a $5,000 credit saves you $5,000 in taxes, regardless of your income level.
Two Types of Energy Credits Available in 2025
The residential clean energy credit provides a 30% tax credit for renewable energy systems. Qualify with solar photovoltaic systems, wind energy systems, geothermal heat pumps, biomass fuel systems, and fuel cell property. The energy-efficient home improvement credit provides a 10% credit for qualified improvements such as insulation, roof replacements, windows, and doors.
Additionally, the residential energy property credit provides a flat credit of $50 to $300 for Energy Star-certified items. Installing an Energy Star-certified heat pump qualifies for $300. A water heater or furnace earns $250. A heat pump water heater earns $300.
How to Document and Claim Energy Credits
To claim energy credits, document all costs and file IRS Form 5695. Keep receipts, invoices, and proof of installation. You don’t need to itemize deductions to claim credits. However, the energy-efficiency credits expire after 2025, making this your final opportunity to claim them on your 2025 tax return filed in 2026.
Pro Tip: If you planned energy improvements for 2026, consider accelerating them into 2025 to capture the tax credits. For example, installing solar panels or a heat pump in December 2025 versus January 2026 could save you thousands in credits.
How Do Mortgage Credit Certificates Benefit First-Time Homebuyers?
Quick Answer: First-time homebuyers with a Mortgage Credit Certificate (MCC) can claim a 10% to 50% tax credit (varying by state) on mortgage interest paid, up to a maximum $2,000 annual credit, without itemizing deductions using IRS Form 8396.
Mortgage Credit Certificates represent a powerful benefit for homebuyers who don’t qualify for conventional deductions. An MCC is issued by state or local government agencies and provides a direct tax credit based on mortgage interest.
Eligibility and Claiming Your MCC
To qualify for an MCC, you must be a first-time homebuyer, which is generously defined as not having owned a home in the past three years. Your lender or mortgage broker can provide an MCC if your state or locality offers the program. Credit rates vary by location, ranging from 10% to 50% of mortgage interest paid, with a maximum annual credit of $2,000.
File Form 8396 with your tax return to claim the MCC credit. Unlike deductions, you don’t need to itemize to benefit from this credit. If your MCC credit exceeds your tax liability, you may carry unused credits forward to future years.
What Tax Advantages Are Available for Real Estate Investors?
Quick Answer: Real estate investors can claim depreciation deductions, cost segregation, rental property deductions, and business expenses. These deductions reduce taxable income and can create significant tax savings, especially when combined with the expanded SALT deduction and other 2025 tax breaks.
Real estate investors have access to unique tax advantages unavailable to primary homeowners. Depreciation allows you to deduct the cost of buildings and improvements over time, even though your property may be appreciating in value.
Depreciation and Cost Segregation Strategies
Depreciation deductions reduce your taxable income by allocating the property’s cost over its useful life. Residential rental properties depreciate over 27.5 years. Commercial properties depreciate over 39 years. Cost segregation studies accelerate depreciation by segregating property components into shorter depreciation periods, creating larger deductions in earlier years.
For example, a $500,000 rental property might normally generate $18,182 in annual depreciation (divided by 27.5 years). A cost segregation study could identify building components like flooring, fixtures, and landscaping that depreciate over 5-15 years, accelerating deductions significantly in the first few years.
Rental Property Deductions and Expense Categories
- Mortgage interest (but not principal)
- Property taxes up to the $40,000 SALT cap
- Insurance premiums and liability coverage
- Maintenance and repairs (not improvements)
- Utilities, advertising, and property management fees
- Capital improvements (depreciated separately)
- Depreciation on buildings and components
Should You Itemize Deductions or Take the Standard Deduction?
Quick Answer: For 2025, compare your total itemized deductions (mortgage interest + SALT up to $40,000 + charitable donations) against the standard deduction of $31,500 (MFJ). If itemized deductions exceed the standard deduction, itemizing saves you money.
One of the most important decisions for homeowners is whether to itemize deductions or claim the standard deduction. The answer depends on your specific situation and the expanded SALT deduction for 2025.
Calculating Your Itemization Threshold
For 2025, married couples filing jointly have a standard deduction of $31,500. Add together your mortgage interest, property taxes, charitable contributions, and state income taxes. If this total exceeds $31,500, itemizing saves you money.
| Filing Status | 2025 Standard Deduction | Itemization Likely If Deductions Exceed |
|---|---|---|
| Married Filing Jointly | $31,500 | $31,500 |
| Single | $15,750 | $15,750 |
| Head of Household | $23,625 | $23,625 |
| Age 65+ (MFJ) | $34,700 | $34,700 |
Example: Comparing Itemization Scenarios
Consider a married couple with $500,000 in mortgage debt, $8,000 annual property taxes, and $3,000 in charitable contributions. Their itemized deductions total $43,000 (interest $32,500 + taxes $8,000 + charity $3,000). This exceeds the $31,500 standard deduction by $11,500, saving them $11,500 in taxable income at their tax bracket.
Pro Tip: High-income real estate investors in states with substantial property taxes should almost always run itemization calculations. The $40,000 SALT cap in 2025 dramatically increases the likelihood of itemizing.
Uncle Kam in Action: How a California Real Estate Investor Saved $24,500 in 2025 Taxes
Client Snapshot: Marcus is a California real estate investor who owns four rental properties and manages a significant real estate portfolio. His combined rental income from the four properties totals $125,000 annually, placing him in the 24% federal tax bracket.
Financial Profile: Marcus earned $125,000 from his rental properties, owned mortgages totaling $1.2 million across his properties, and faced California state income taxes of $11,500 plus approximately $22,000 in combined property taxes across his portfolio.
The Challenge: Previously, under the $10,000 SALT deduction cap, Marcus could only deduct $10,000 of his substantial property taxes and state income taxes. This limitation created a significant tax burden on his rental income. Additionally, Marcus hadn’t fully optimized his depreciation strategy across his properties.
The Uncle Kam Solution: Uncle Kam implemented a comprehensive 2025 tax strategy that included (1) Maximizing the new $40,000 SALT deduction cap by itemizing all property taxes and state income taxes, (2) Implementing cost segregation studies on two of his oldest properties to accelerate depreciation, (3) Documenting all rental property expenses including repairs, maintenance, insurance, and property management fees, and (4) Strategic planning for energy-efficient improvements at one property to capture the 2025 energy credits before expiration.
The Results:
- Tax Savings: $24,500 in reduced federal income taxes for 2025
- Investment: $6,900 service fee for comprehensive tax strategy and cost segregation studies
- Return on Investment (ROI): 3.55x return in the first year alone (his savings of $24,500 divided by $6,900 investment)
This is just one example of how comprehensive tax strategy implementation helps real estate investors maximize their deductions while maintaining full compliance with IRS regulations. Marcus’s multi-year strategy also positioned him for continued savings as he captures additional depreciation benefits from the cost segregation studies over the next five years.

Frequently Asked Questions
Can I claim mortgage interest if I don’t itemize deductions?
No. The mortgage interest deduction only applies if you itemize deductions on Schedule A. If you claim the standard deduction, you cannot deduct mortgage interest separately. However, evaluate whether itemizing (including mortgage interest, property taxes, and other deductions) exceeds your standard deduction amount.
What if my mortgage balance exceeds $750,000?
If your mortgage was issued after December 15, 2017, the $750,000 limit applies. Mortgages issued before that date can deduct interest up to $1,000,000 of debt. Calculate the interest deduction on the allowable portion only. For example, a $900,000 post-2017 mortgage would only allow deduction on $750,000 of the balance.
Is the $40,000 SALT deduction permanent?
Yes. Under the One Big Beautiful Bill Act, the $40,000 SALT deduction cap is permanent through 2028. However, Congress could change this provision in future legislation. For now, you can reliably plan on this limit through 2028.
When do energy-efficient credits expire?
The energy-efficient home improvement credit and residential clean energy credit expire after the 2025 tax year. If you plan energy improvements, complete them by December 31, 2025, to claim the credits on your 2025 return filed in 2026. Improvements made in 2026 or later do not qualify.
Can I claim both mortgage interest deduction and Mortgage Credit Certificate?
Yes. You can claim both if you qualify. The MCC provides a direct tax credit, while the mortgage interest deduction reduces taxable income. However, if you claim an MCC, the mortgage interest used to calculate the credit cannot be claimed again as a deduction.
What real estate expenses can I deduct for rental properties?
Deductible rental property expenses include mortgage interest, property taxes, insurance, utilities, maintenance and repairs (but not capital improvements), property management fees, advertising costs, and depreciation. Keep detailed records of all expenses and separate capital improvements (depreciated over time) from repairs.
Should I do a cost segregation study on my rental property?
Cost segregation studies can significantly accelerate depreciation deductions, especially in the first few years of ownership. Properties purchased before 2023 and buildings with a basis over $1 million generally benefit most. A qualified tax professional can evaluate whether a cost segregation study makes financial sense for your specific property.
Can I deduct home office expenses if I’m a homeowner?
Yes. If you use part of your home exclusively and regularly for business, you can deduct home office expenses using the simplified method ($5 per square foot, up to 300 square feet) or actual expense method. Use IRS Form 8829 to claim these deductions, which are separate from homeowner deductions.
