Homeowners could see changes to homeowner tax deductions in 2026 under the “One, Big, Beautiful Bill” Act. The IRS says the law was signed on July 4, 2025, as Public Law 119-21.
Many provisions take effect for 2025 returns, while others start in 2026. The details matter because timing affects withholding and estimated payments. Taxpayers may also revisit whether itemizing still makes sense.
The homeowner impact centers on deductions and credits tied to housing costs. Some rules expand itemized deductions in the near term. Other rules narrow the credits available for energy upgrades. Planning now can reduce surprises at filing time, especially for high-tax states.
SALT Cap Rises For Many Itemizers
The biggest change for many homeowners is the higher SALT cap. The SALT deduction covers certain state and local taxes, including property taxes. It only helps taxpayers who itemize deductions. Under the updated rule, the SALT cap increases to $40,000 for tax years 2025 to 2029. That is a sharp increase from the prior $10,000 cap, which has applied since 2018.
The higher cap is not unlimited for high earners. The H&R Block summary describes a phase-down for taxpayers with modified adjusted gross income above $500,000. It also notes a floor that does not drop below $10,000.
That design concentrates benefits among homeowners who already itemize. It may also shift the break-even point between itemizing and taking the standard deduction.
The practical impact depends on your state and your tax bill. Households with large property taxes often hit the cap quickly. A higher cap can reduce taxable income for qualifying filers. It can also affect the value of other itemized deductions, such as mortgage interest.
Mortgage Interest And PMI Get Clearer Treatment
The law also locks in key mortgage-related rules. H&R Block says the mortgage interest deduction limit is now permanent.
That matters because earlier law had a sunset date tied to broader tax provisions. Permanent rules can simplify planning for long mortgage horizons. They can also reduce uncertainty for buyers considering refinancing.
Private mortgage insurance now gets a clearer path to deductibility. H&R Block says PMI will be treated as deductible mortgage interest beginning in 2026.
This change targets borrowers who put down less than 20%. Those households often face tight monthly budgets early in ownership. A deductible premium could lower after-tax housing costs for itemizers.
The deduction still depends on your filing profile. Taxpayers generally must itemize to benefit from mortgage interest deductions. Income limits and other eligibility rules can also apply, depending on final guidance. Households should keep annual PMI statements and lender forms.
Energy Credits Shrink After 2025
The law also tightens energy incentives tied to home upgrades. H&R Block says energy-related tax credits, including solar panel credits, expire after 2025.
The IRS has also published resources that track clean energy credit modifications under the law. That timing can matter for homeowners planning installations, audits, or major equipment changes. It can also affect contractor demand and project pricing.
This change does not affect every household equally. Credits are available only to taxpayers with qualifying expenses and sufficient tax liability. Yet they can be meaningful for large projects with high upfront costs. If a credit ends after 2025, the project schedule becomes a tax variable.
For planning purposes, the main trade-off is between deductions and credits. Deductions reduce taxable income and depend on your marginal rate. Credits directly reduce tax owed and often offer more punch. Homeowners should compare scenarios before committing to large upgrades.
Taxpayers may also face year-to-year shifts in the best strategy. Higher SALT capacity could increase the odds of itemizing in some households. New PMI treatment could strengthen that case for newer borrowers. A smaller menu of energy credits could push decisions toward cost rather than tax support.
