Most new homeowners overpay their taxes by at least $1,200 in their first year. Not because they cheat — because they guess wrong on what’s deductible. The standard deduction for 2026 is projected at $15,000 for single filers and $30,000 for married couples filing jointly. If your itemized deductions don’t beat those numbers, you get zero benefit from owning a home on your tax return. Here’s what actually works and what doesn’t.
Mortgage Interest: The Big One, With Limits
This is the deduction everyone talks about. But the rules changed in 2018 under the Tax Cuts and Jobs Act, and those rules still apply in 2026.
You can deduct interest on up to $750,000 of mortgage debt for loans taken after December 15, 2017. For older loans, the limit is $1 million. That’s acquisition debt — money used to buy, build, or substantially improve your home.
Here’s where people mess up. Home equity loan interest is only deductible if you used that money to improve the house. Took out a $30,000 home equity line to pay off credit cards? That interest is not deductible. Used that same $30,000 to add a second bathroom? Fully deductible.
Your lender sends Form 1098 showing how much interest you paid. In 2026, expect to receive this by January 31. A typical $400,000 mortgage at 6.5% generates roughly $25,800 in interest the first year. That alone beats the standard deduction for a single filer. But if your mortgage is $250,000 at 5%, first-year interest is about $12,400 — below the $15,000 standard deduction threshold. You’d need other itemized deductions to make itemizing worthwhile.
Verdict: This deduction works best for large mortgages in early years. For smaller loans or lower rates, the standard deduction often wins.
Property Taxes: Capped at $10,000
The state and local tax (SALT) deduction caps property taxes plus state income taxes at $10,000 total. This applies single or married filing jointly.
If your annual property tax bill is $8,000 and you paid $3,000 in state income tax, you can only deduct $10,000 of that $11,000 combined. The extra $1,000 is lost.
This cap hits homeowners in high-tax states hardest. In Texas, average property taxes run around 1.6% of home value. On a $350,000 home, that’s $5,600 — well under the cap. But in New Jersey, where rates average 2.2%, that same home generates $7,700. Add state income tax, and you hit the cap fast.
One strategy: if you’re buying in late 2026, consider paying next year’s property tax early if it helps you cross the itemization threshold this year. But only if you’re sure itemizing beats the standard deduction. Otherwise, you’re just prepaying a bill with no tax benefit.
Points: The One-Time Deduction Most People Miss
Mortgage points — also called discount points — are prepaid interest. Each point costs 1% of your loan amount and typically lowers your rate by 0.25%.
Here’s the good news: points paid on a purchase mortgage are fully deductible in the year you buy the home, as long as the points are standard for your area and you didn’t pay more than usual. No amortization needed. Pay 2 points on a $300,000 loan? That’s a $6,000 deduction in year one.
Refinance points work differently. Those must be deducted over the life of the loan — typically 30 years. If you refinance again or pay off the loan early, you can deduct the remaining unamortized points in that year.
Failure mode: Many taxpayers forget to claim points at all. Your closing disclosure shows them. Your Form 1098 may or may not list them separately. Check box 2 on your 1098. If it’s blank, look at your settlement statement and add the points manually.
What You Cannot Deduct (And What Replaces It)
Several old homeowner deductions disappeared after 2018 and haven’t returned. Here’s what’s gone:
- Moving expenses — only deductible for active-duty military now
- Home equity loan interest — unless used for home improvement (covered above)
- PMI (private mortgage insurance) — this expired after 2026 and has not been reinstated for 2026
- General home improvements — new roof, new HVAC, new windows? Not deductible. They add to your cost basis, which reduces capital gains when you sell, but they don’t reduce your annual tax bill
The one exception: energy efficiency improvements. The Inflation Reduction Act extended credits through 2032. Installing solar panels gets you a 30% federal tax credit with no dollar cap. Heat pumps, insulation, and energy-efficient windows qualify for smaller credits up to $2,000 total per year. These are credits — they reduce your tax bill dollar-for-dollar, which is better than a deduction.
Verdict: Don’t confuse credits with deductions. Credits are more valuable.
Home Office Deduction: Tight Rules, Real Benefit
If you’re self-employed or a freelancer working from home, the home office deduction is available. But employees working remotely for an employer cannot claim it — the Tax Cuts and Jobs Act suspended that through 2026, and no extension has been passed for 2026.
For self-employed workers, the rules are strict:
- The space must be used exclusively and regularly for business. Your dining room table where you also eat dinner doesn’t count.
- You can use the simplified method: $5 per square foot, up to 300 square feet, for a maximum deduction of $1,500. No paperwork beyond square footage.
- Or use the regular method: calculate actual expenses (mortgage interest, utilities, insurance, repairs) based on the percentage of your home used for business. A 200-square-foot office in a 2,000-square-foot home means 10% of those costs become deductible.
The regular method gives a larger deduction if you have high housing costs. But it requires detailed records and Form 8829. The simplified method is easier and still provides a real benefit — $1,500 off your self-employment income.
Common mistake: Claiming a home office deduction triggers an audit. It doesn’t. The IRS sees millions of these claims every year. As long as your math is correct and the space is genuinely used for business, you’re fine.
| Deduction | 2026 Limit | Best For | Common Mistake |
|---|---|---|---|
| Mortgage interest | $750,000 loan max | Large mortgages, early years | Forgetting home equity loan rules |
| Property tax (SALT) | $10,000 combined | Low-to-moderate tax states | Double-counting state income tax |
| Mortgage points | Fully deductible at purchase | Buyers who paid points | Not claiming them at all |
| Home office | $1,500 simplified / actual expenses | Self-employed workers | Employees trying to claim it |
| Energy credits | 30% solar / $2,000 other | Green upgrades | Treating as deduction vs credit |
The real shift coming for homeowners in 2026 isn’t new deductions — it’s the continued erosion of itemizing’s value. With standard deductions rising with inflation, fewer homeowners will benefit from itemizing each year. Run the numbers before assuming homeownership cuts your tax bill. For many, the biggest financial win isn’t the deduction — it’s building equity and locking in a fixed housing payment while rents climb.
