What Tax Deductions Homeowners Should Know About: A First-Time Homeowner’s Guide

Buying your first home in 2026 is exciting—but it comes with responsibilities, especially when it comes to taxes. Many first-time homeowners don’t realize that owning a home opens the door to tax deductions for homeowners that can save thousands of dollars each year. From mortgage interest to energy-efficient upgrades, knowing what you can deduct and plan for can make a real difference in your finances.

In this guide, we break down all the tax deductions first-time homeowners can claim, what you might qualify for now, and what credits or deductions you could claim in the future.

Mortgage Interest Deduction

One of the largest tax deductions for first-time homebuyers is the mortgage interest deduction.

• How it works: Interest paid on loans up to $750,000 for mortgages taken out after December 15, 2017, is deductible. For older mortgages, the limit is $1 million. This means that in the first few years of your mortgage, when a larger portion of your monthly payments goes toward interest, your potential deduction is highest.
• Why it matters: Mortgage interest is often the single largest deductible expense for homeowners. For a $300,000 mortgage with a 4% interest rate, you could deduct roughly $12,000 in interest in the first year alone, which can significantly reduce taxable income.
• Tips: Keep Form 1098 from your lender and track your mortgage payments carefully. Consider itemizing deductions instead of taking the standard deduction if your total deductions exceed it.

Property Tax Deduction

Property taxes are another important homeowner tax benefit that can significantly reduce your taxable income.

• How it works: You can generally deduct state and local property taxes you pay on your primary residence and any secondary homes. For example, if your annual property tax is $6,000, you may be able to deduct that full amount (subject to the SALT cap) when filing federal taxes.
• Important limits: The deduction for state and local taxes (SALT) is capped at $10,000. This includes property taxes, state income taxes, or sales taxes combined. In high-property-tax areas, this can affect the total deduction you claim, so it’s important to plan accordingly.
• Tips: Keep careful records of all property tax payments and make sure you itemize deductions if it provides a larger benefit than the standard deduction.

Home Office Deduction

If you work from home, you may qualify for a home office deduction, which allows you to deduct expenses related to the space you use for work.

• Eligibility: The space must be used regularly and exclusively for business. This applies to self-employed individuals, freelancers, and some side-business owners.
• Deductible expenses: You may deduct a portion of your mortgage interest, utilities, repairs, and even depreciation based on the percentage of your home used for business.
• Tips: Keep a detailed log of the square footage of your home office versus your entire home, and save all receipts for related expenses. For instance, if your office takes up 10% of your home, you can deduct 10% of eligible expenses.

Points on a Mortgage

Paying points at closing can reduce your mortgage interest rate and also provide a tax benefit.

• Example: If you pay $3,000 in points to lower your interest rate, you may be able to deduct that full amount in the year you purchase your home.
• Refinancing points: If points are paid to refinance, the deduction is generally spread over the life of the loan rather than claimed immediately.
• Tips: Always check with a tax professional to understand how points impact your specific tax situation.

Private Mortgage Insurance (PMI) Deduction

Private Mortgage Insurance is often required for homeowners who put down less than 20% of the home’s purchase price.

• Deduction: PMI premiums may be tax-deductible, depending on income limits. This can save hundreds to thousands of dollars each year.
• Tips: Ensure you track your PMI payments and verify your eligibility each tax year.

Energy-Efficient Home Upgrades

Making your home more energy-efficient not only lowers utility bills but may also qualify for federal tax credits.

• Eligible improvements: Solar panels, water heaters, windows, doors, insulation, and HVAC systems.
• Tips: Always keep receipts and documentation, and check that your improvements meet IRS standards.
