Homeowner Tax Benefits Guide

Homeownership comes with significant tax advantages that renters don't receive — and understanding them can save you thousands of dollars each year. This guide covers the major federal tax benefits available to Michigan homeowners, plus state-specific considerations.

Mortgage Interest Deduction

This is the largest and most well-known homeowner tax benefit:

• What qualifies: Interest paid on a mortgage used to buy, build, or substantially improve your primary residence (and one additional qualified residence). Interest on up to $750,000 of mortgage debt ($375,000 for married filing separately) is deductible for loans originated after December 15, 2017.
• You must itemize: The mortgage interest deduction is only available if you itemize deductions on Schedule A. For many homeowners — especially those with smaller mortgages or who bought when rates were lower — the standard deduction ($15,000 single / $30,000 married filing jointly for 2026) may exceed total itemized deductions, making the mortgage interest deduction irrelevant.
• Points deduction: If you paid points (prepaid interest) to get a lower rate when buying your home, those points are generally deductible in the year you paid them. Points paid on a refinance are typically deducted over the life of the loan.
• Late payment charges: Late payment penalties on your mortgage are not deductible as mortgage interest.

Property Tax Deductions

Michigan property taxes can be significant, especially in communities with higher millage rates. Here's what you can deduct:

• State and local tax (SALT) deduction: You can deduct property taxes PLUS state and local income taxes OR sales taxes — but the combined deduction is capped at $10,000 ($5,000 for married filing separately). For many Michigan homeowners, this is the most painful limitation, as property taxes alone can approach or exceed the cap in higher-value communities like Birmingham, Rochester Hills, and West Bloomfield.
• Michigan's Principal Residence Exemption (PRE): While not a federal tax deduction, Michigan's PRE exempts your primary residence from the 18 mills of school operating tax. This is a significant savings and requires filing Form 2368 with your local assessor. If you move, you must rescind the PRE on your previous home and file for it on your new one.
• Escrow considerations: You can only deduct property taxes actually paid during the tax year, not the amount deposited into your escrow account. Your lender's year-end statement (Form 1098) will show the actual taxes paid.

Home Office Deduction

With remote and hybrid work now common, the home office deduction is more relevant than ever — but the rules are specific:

• Who qualifies: The home office deduction is available to self-employed individuals and independent contractors — NOT to W-2 employees, even if you work from home 100% of the time. This is a common point of confusion.
• Exclusive and regular use: The space must be used exclusively and regularly for business. A guest bedroom where you occasionally work doesn't qualify. A dedicated office used only for business does.
• Simplified method: Deduct $5 per square foot of dedicated office space, up to 300 square feet ($1,500 maximum). This is simpler than the regular method, which involves calculating actual expenses (mortgage interest, utilities, insurance, depreciation) proportional to the office's percentage of your home's square footage.

Capital Gains Exclusion When Selling

This is arguably the most valuable tax benefit for homeowners — and one that many don't fully understand:

• Section 121 exclusion: If you've owned and lived in your home as your primary residence for at least 2 of the 5 years before the sale, you can exclude up to $250,000 of capital gains ($500,000 for married couples filing jointly). This means most homeowners pay no federal tax on their home sale profit.
• How it works: If you bought your Grand Blanc home for $200,000 and sell it for $350,000, your gain is $150,000. As a single filer, the entire gain is excluded — no tax owed. As a married couple, you could exclude up to $500,000, which covers most Mid-Michigan home sales completely.
• Partial exclusion: If you sold due to a change in employment, health reasons, or unforeseen circumstances (and lived in the home less than 2 years), you may qualify for a partial exclusion.
• Record keeping matters: Keep records of home improvements — new roof, kitchen remodel, finished basement, new HVAC — because these increase your cost basis and reduce your taxable gain. Without documentation, you can't claim these adjustments.
• Michigan state tax: Michigan generally follows federal treatment for capital gains on home sales, with the same exclusion applying at the state level for qualifying primary residence sales.

Energy Efficiency Tax Credits

The Inflation Reduction Act expanded and extended federal tax credits for energy-efficient home improvements:

• Residential Clean Energy Credit: 30% of the cost of solar panels, solar water heaters, geothermal heat pumps, small wind turbines, and battery storage (with capacity of 3 kWh or more). No annual or lifetime limit. A $20,000 solar installation qualifies for a $6,000 credit.
• Energy Efficient Home Improvement Credit: Up to $1,200 annually for qualifying improvements, including:
  • $600 for exterior windows and skylights
  • $500 for exterior doors ($250 per door)
  • $600 for central air conditioners, furnaces, boilers, and water heaters
  • $150 for home energy audits
• Heat pump credit (separate limit): Up to $2,000 annually for qualifying heat pumps and heat pump water heaters.

Michigan-Specific Tax Considerations

• Michigan income tax rate: Michigan has a flat 4.25% state income tax (as of 2026). The SALT deduction cap affects how much state income tax and property tax you can deduct federally.
• Michigan Homestead Property Tax Credit: A credit available to lower-income homeowners and renters. For 2026, homeowners with total household resources of $63,000 or less may qualify. The credit is based on property taxes that exceed 3.5% of total household resources, up to a maximum of $1,700. File Michigan Form MI-1040CR.
• Disabled Veterans Exemption: Michigan offers a full property tax exemption for honorably discharged veterans who are 100% disabled (or individually unemployable) due to service-connected disabilities. File with your local assessor.
• Poverty Exemption: Michigan allows municipalities to grant property tax exemptions to homeowners below federal poverty guidelines. Application is through your local township or city assessor.

Keeping Records for Tax Purposes

Good records are the foundation of maximizing your tax benefits and avoiding problems if you're audited:

• Closing documents: Keep your HUD-1 or Closing Disclosure permanently. It establishes your purchase price (cost basis) and documents points paid and property tax allocations.
• Home improvement receipts: Keep receipts, contracts, and permits for every improvement — not repairs, but capital improvements that add value, extend the home's life, or adapt it to new uses. These increase your cost basis and reduce taxable gain when you sell. Keep these for the entire time you own the home plus 3 years after you sell.
• Annual tax records: Keep Form 1098 (mortgage interest statement), property tax bills and receipts, and energy efficiency certification documents for 3–7 years.
• Digital backup: Scan and store all tax-related documents in cloud storage. Paper receipts fade, and fires happen.
