First-Year Homebuyer's Tax Toolkit: What You Can Actually Deduct in 2026
Meta: New homeowner in 2026? Learn which closing costs are deductible (mortgage interest, points, property taxes under the new $40,400 SALT cap) and which aren't. Free worksheet inside.
You've signed the mountain of paperwork, received the keys, and celebrated your first night in the new home. But buried in that closing disclosure are tax opportunities—and traps—that could save or cost you thousands come April.
Most first-time buyers assume that since they spent so much at closing, they must get a big tax break. Unfortunately, most closing costs are NOT deductible.
The good news? Two major changes just took effect that make 2026 a landmark year for homeowners:
- The SALT cap increased to $40,400 for joint filers (up from $10,000), giving homeowners in high-tax states a huge new deduction opportunity.
- The $750,000 mortgage limit is now permanent under the One Big Beautiful Bill Act (OBBBA).
This toolkit will walk you through exactly what you can deduct in your first year, what can't, and how to calculate whether itemizing beats the standard deduction.
The First-Year Homebuyer's Golden Rule: Cost Basis vs. Deductions
Before diving into specific deductions, every new homeowner must understand this fundamental concept:
- Deductible costs: Reduce your taxable income this year (claimed on Schedule A)
- Cost basis additions: Don't help you now, but reduce your capital gains tax when you sell the home years later
Why it matters: If you pay $8,000 in non-deductible closing costs, those dollars aren't "wasted." They increase your home's tax basis, potentially saving you thousands in capital gains tax when you sell—especially if your profit exceeds the $250,000/$500,000 exclusion.
What Goes Into Your Cost Basis
Your starting basis = Purchase price + certain settlement fees and closing costs:
- Title insurance
- Recording fees
- Attorney fees
- Survey costs
- Transfer taxes
- Notary fees
- Credit report fees
- Appraisal fees
- Home inspections
📌 Tax Tip: Keep your closing disclosure (CD) and all settlement statements with your permanent records. You'll need them years from now when calculating gain or loss on sale.
What IS Deductible in Your First Year
To deduct any homeownership costs, you must itemize deductions on Schedule A instead of taking the standard deduction. For 2026, the standard deduction is projected at ~$30,000 for married couples filing jointly and ~$15,000 for single filers.
1. Mortgage Interest (The Big One)
What's deductible: Interest paid on acquisition debt—loans used to buy, build, or substantially improve your home.
The 2026 limits:
- $750,000 maximum loan balance for mortgages originated after December 15, 2017 (now permanent under OBBBA)
- $1 million for mortgages originated before December 16, 2017 (grandfathered)
How it works: Your lender will send Form 1098 showing the interest you paid. If your loan exceeds the limit, you must calculate the deductible portion:
Deductible interest = (Limit ÷ Actual loan amount) × Total interest paid
Example: $900,000 loan, $54,000 interest paid → ($750,000 ÷ $900,000) × $54,000 = $45,000 deductible
2. Points (Loan Origination Fees)
The good news: Points paid to get a mortgage on your primary residence are generally fully deductible in the year paid—unlike refinance points, which must be amortized.
IRS requirements for full deduction:
- Loan must be to buy or build your main home
- Points must be figured as a percentage of the loan
- Points must be clearly shown on your closing disclosure
- You can't borrow the money to pay the points
Discount points (paid to lower your rate) also qualify as deductible prepaid interest.
3. Prepaid Interest
At closing, you'll pay prepaid interest covering the period between closing and your first payment due date. This interest is fully deductible in the year paid.
Calculation: Loan amount × Interest rate ÷ 365 × Days from closing to month-end
Example: $400,000 at 6.5%, closing January 15 → $71.23 daily interest × 16 days = $1,140 deductible
4. Property Taxes (With the New $40,400 SALT Cap)
What's deductible: State and local real estate taxes actually paid during the year.
The 2026 SALT cap: Under OBBBA, the limit increased to $40,400 for joint filers ($20,200 for married filing separately) for 2026.
Important nuances:
- You can only deduct taxes actually paid to the taxing authority, not amounts held in escrow
- At closing, you typically reimburse the seller for taxes they prepaid—these reimbursements count toward your deduction
- The SALT deduction phases out for high-income earners (MAGI over ~$505,000 in 2026)
5. Private Mortgage Insurance (PMI) — BACK for 2026
Major update: The One Big Beautiful Bill Act permanently reinstated the treatment of mortgage insurance premiums as qualified mortgage interest for tax years beginning after 2025.
What this means: If you put less than 20% down and pay PMI, those premiums are now deductible—subject to income phase-outs.
Phase-out rules: Deduction phases out ratably by 10% for each $1,000 of AGI over $100,000 ($50,000 for MFS), disappearing entirely at $109,000 AGI.
What Is NOT Deductible (But Adds to Basis)
These common closing costs provide no immediate tax benefit but increase your home's cost basis:
| Cost Type | Examples | Tax Treatment |
|---|---|---|
| Title fees | Title insurance, title search, settlement fees | Add to basis |
| Government fees | Recording fees, transfer taxes, notary fees | Add to basis |
| Inspections | Home inspection, pest inspection, flood certification | Add to basis |
| Appraisal | Appraisal fee (even if required by lender) | Add to basis |
| Credit report | Credit check fees | Add to basis |
| Attorney fees | Legal fees related to purchase | Add to basis |
| Homeowners insurance | Premiums (even prepaid at closing) | NOT deductible, NOT added to basis |
| HOA dues | Prepaid HOA fees | NOT deductible, NOT added to basis |
| Down payment | Any amount paid toward principal | NOT deductible, adds to basis |
Why basis matters: If you later sell for a gain exceeding the exclusion ($250,000 single/$500,000 married), a higher basis reduces your taxable gain.
The 2026 First-Year Homebuyer's Deduction Worksheet
Use this worksheet to determine if itemizing beats the standard deduction:
Step 1: Gather Your Documents
- Closing Disclosure (CD) or HUD-1
- Form 1098 from lender
- Property tax receipts / escrow statement
Step 2: Calculate Deductible Interest
Loan amount: $_________ Over $750k? ☐ Yes ☐ No
If yes: Total interest × ($750,000 ÷ loan) = deductible: $_________
Step 3: Add Points Paid at Closing
Points (Line A of CD): $_________
Step 4: Add Prepaid Interest
Per diem interest (Section F): $_________
Step 5: Add Property Taxes Paid
Taxes at closing + paid directly: $_________ (subject to $40,400 cap)
Step 6: Add PMI (if applicable & AGI phase-out)
PMI paid: $_________ AGI >$100k? ☐ Yes (reduce accordingly)
Step 7: Total Itemized Deductions
Add Steps 2–6: $_________
Step 8: Compare to Standard Deduction
2026 std: $30,000 (MFJ) / $15,000 (single). If total > standard → Itemize!
Step 9: Non-Deductible Costs (add to basis)
Total non-deductible from table: $_________ (save for future)
Real-World Scenarios
Scenario A: Married, $400k home, $380k loan 6.5%, 20% down → itemized $31,300 → beats $30k → itemize
Scenario B: Single, $800k home, $750k loan 7% → itemized $69,500 → beats $15k → itemize
Scenario C: Married, $250k home, $200k 5% → itemized $14,800 → below $30k → take standard
Documentation: What to Save and Why
| Document | Where to Find | Why You Need It |
|---|---|---|
| Closing Disclosure | Lender / title co. | Points, prepaid interest, property taxes, basis costs |
| Form 1098 | Mailed by lender | Reports mortgage interest paid to IRS |
| Property tax receipts | County / escrow | Proves taxes paid for SALT deduction |
| Improvement receipts | Your records | Future basis adjustments when selling |
| PMI statements | Lender | Documents PMI premiums for deduction |
💡 Pro Tip: Create a "Home Basis" folder now. Every time you make a capital improvement, add the receipt. Your future self (or your heirs) will thank you.
