Tax Planning for Homeowners
Covers mortgage interest deductions, SALT limits, energy credits, and home sale exclusions available to homeowners in 2026.
TL;DR
- 01Itemize deductions when they exceed the 2026 standard deduction of $16,100 single.
- 02Deduct interest on mortgage loans up to $750,000 for two homes.
- 03Exclude up to $250,000 in gains on a qualifying home sale.
Tips
- 01Keep a home improvement folder with receipts for every project, since this documentation directly reduces your taxable gain when you sell.
- 02Prepay January mortgage interest or property taxes in December to push more deductions into the current tax year.
- 03Document every capital improvement carefully, since these costs raise your cost basis and shrink taxable gains at sale.
Warnings
- 01Assuming itemizing always beats the standard deduction is a mistake, so run the numbers every year before choosing.
- 02Property taxes plus state income or sales taxes are capped at $40,400 combined for 2026, with the cap phasing down for taxpayers with MAGI above $505,000.
- 03Claiming a home office without exclusive business use can disqualify the deduction entirely, since shared rooms like a dining area don't qualify.
Homeowner Tax Benefits Overview
Homeownership comes with several federal tax benefits. However, many only apply when you itemize deductions on Schedule A rather than taking the standard deduction.
- 2026 standard deduction: $16,100 (single), $32,200 (married filing jointly), $24,150 (head of household).
- Itemizing makes sense only if your total deductions — mortgage interest, property taxes, charitable contributions, and others — exceed the standard deduction.
- Homeowners with large mortgages or high property taxes in expensive markets are most likely to benefit from itemizing.
Key Deductions and Credits
| Benefit | Limit | Notes |
|---|---|---|
| Mortgage interest deduction | Loans up to $750,000 | Primary and secondary residences only |
| Property tax deduction (SALT) | $40,400 cap (single and MFJ), phasing down above $505,000 MAGI | Combined state, local, and property taxes |
| Home office deduction | $1,500 max (simplified method) | Self-employed only; exclusive business use required |
| Energy Efficient Home Improvement Credit | 30%, up to $3,200/year | Windows, insulation, heat pumps, and more |
| Residential Clean Energy Credit | 30% of cost, no annual cap | Solar panels, battery storage, geothermal systems |
| Mortgage insurance premiums | Subject to AGI phase-out | Verify current year deductibility with IRS |
- Mortgage discount points paid at closing to reduce your interest rate are generally fully deductible in the year paid for a home purchase. For refinanced mortgages, points must be deducted over the loan term.
- Casualty losses from federally declared disasters may be deductible on Schedule A.
Home Sale Capital Gains Exclusion
When you sell your primary home, you may exclude up to $250,000 in capital gains from taxable income ($500,000 for married filing jointly) under IRS Section 121.
Eligibility requirements:
You must have owned the home for at least 2 of the last 5 years.
You must have lived in it as your primary residence for at least 2 of the last 5 years.
You cannot have used this exclusion within the past 2 years.
Gains above the exclusion limit are taxed at long-term capital gains rates (0%, 15%, or 20% depending on income).
Track your cost basis carefully: include the original purchase price plus the cost of qualifying capital improvements (additions, roof replacement, HVAC systems, etc.).
Strategies to Maximize Savings
- Bunch deductible expenses into one tax year to push itemized deductions above the standard deduction. For example, prepay January mortgage interest in December.
- Prepay property taxes before December 31 to claim the deduction in the current year — but stay within the $40,400 SALT cap (2026), and watch the phase-down if your MAGI exceeds $505,000.
- Document all capital improvements with receipts and records. These raise your cost basis and reduce taxable gains when you sell.
- Time energy-efficient upgrades to maximize the $3,200 annual Energy Efficient Home Improvement Credit across multiple years.
- Consider a home equity loan for deductible purposes: interest on home equity debt is only deductible when the funds are used to buy, build, or substantially improve the home securing the loan.
Common Pitfalls to Avoid
- Assuming itemizing is always better: run the numbers each year. Many homeowners with smaller mortgages save more with the standard deduction.
- Ignoring the SALT cap: property taxes plus state income or sales taxes are capped at $40,400 combined for 2026, with the cap phasing down for taxpayers whose MAGI exceeds $505,000. Amounts above the applicable limit are not deductible.
- Claiming a home office without exclusive use: the space must be used exclusively and regularly for business. Shared rooms do not qualify.
- Missing the home sale exclusion: taxpayers who move frequently or rent their home before selling may not meet the 2-of-5-year residency test.
- Overlooking energy credit requirements: some credits require specific efficiency certifications or product ratings. Verify eligibility before purchasing.
FAQ
Itemize only if your total deductions, including mortgage interest, property taxes, and charitable contributions, exceed the standard deduction of $16,100 (single) or $32,200 (married filing jointly) for 2026. Homeowners with large mortgages or high property taxes in expensive markets benefit most. Run the comparison every year, since your deductible expenses can change.
You can deduct interest on mortgage loans up to $750,000 for a primary and secondary residence combined. Discount points paid at closing on a home purchase are generally fully deductible in the year paid. For a refinance, points must be deducted gradually over the loan term instead.
You can exclude up to $250,000 in capital gains ($500,000 if married filing jointly) under IRS Section 121, provided you owned and lived in the home as your primary residence for at least 2 of the last 5 years. Gains above the exclusion are taxed at long-term capital gains rates. You can't use this exclusion again within 2 years of your last sale.
Renting your home for more than 14 days a year turns it into a rental property under different tax rules, which can affect your mortgage interest deduction and the home sale exclusion. Track rental days carefully if you list on a short-term rental platform. Consult a tax professional before converting any portion of your primary residence to rental use.
