Homeowner Tax Benefits: Deductions and Credits You Should Know
Homeownership remains one of the best ways to build wealth, and the tax code provides several incentives to make it even more financially advantageous. Here are the key tax benefits every homeowner should know about.
Mortgage Interest Deduction
You can deduct interest paid on mortgage debt up to $750,000 ($375,000 if married filing separately) for homes purchased after December 15, 2017. For older mortgages, the limit is $1 million. This is often the largest itemized deduction for homeowners.
Property Tax Deduction
State and local property taxes are deductible as an itemized deduction, subject to the $10,000 SALT (State and Local Tax) cap. This cap includes property taxes plus state and local income or sales taxes combined.
Home Sale Exclusion
- Exclude up to $250,000 in capital gains on your primary residence (single)
- Exclude up to $500,000 if married filing jointly
- Must have owned and lived in the home for at least 2 of the last 5 years
- Can be used repeatedly (once every 2 years)
Energy Efficiency Tax Credits
- Residential Clean Energy Credit: 30% of costs for solar panels, solar water heaters, and battery storage
- Energy Efficient Home Improvement Credit: Up to $3,200 annually for insulation, windows, doors, heat pumps, and HVAC systems
- These are tax credits, not deductions — they directly reduce your tax bill
Should You Itemize?
With the 2025 standard deduction at $15,000 (single) or $30,000 (married filing jointly), many homeowners find that their mortgage interest and property taxes alone do not exceed the standard deduction. Run the numbers each year to determine which approach saves you more.
