Quick answer: A homeowner who itemizes may deduct qualifying home mortgage interest, eligible points and state and local real property taxes within current limits. Most principal, insurance, utilities, HOA fees and repairs are personal and nondeductible. Credits or business and rental use follow separate rules.
This guide translates the controlling rule into filing and recordkeeping steps. It reflects official material available on August 17, 2026. Tax-year forms, software features, state rules and agency procedures can change, so use the instructions for the exact year and transaction involved.
At a glance
| Question | Practical answer |
|---|---|
| Who this applies to | Owners of a main home or qualifying second home preparing an individual return |
| What this does not cover | Rental-property expenses, home-sale exclusion, or automatic deductions for every closing cost |
| Where it is handled | Schedule A, Form 8396 when an MCC applies, and other forms for business or energy items |
How the rule works
Start by identifying the legal character of the payment, account, credit, deduction, benefit or loan. A marketing label does not control the tax result. Dates, ownership, business purpose, filing status, income limits, residency and documentation can turn a superficially similar situation into a different answer.
- Mortgage interest must be on secured qualified-home debt and generally on proceeds used to buy, build or substantially improve the home.
- The acquisition-debt limit depends on when the mortgage originated and applies across the main and second home.
- Real property taxes join other state and local taxes under the current SALT limit and income phase-down rules.
- Certain acquisition points can be deducted in the year paid; other points are spread over the loan term.
- The residential clean-energy and energy-efficient improvement credits ended for new post-2025 expenditures, although prior carryforwards may remain.
Practical example
A homeowner pays $14,000 mortgage interest, $8,000 property tax, $1,800 insurance and $600 HOA fees. The first two may enter itemized-deduction calculations if all rules are met; insurance and HOA fees remain personal. The homeowner compares total itemized deductions with the 2026 standard deduction.
This example isolates the principal rule. It is not a complete return calculation: phaseouts, other credits, state conformity, related-party rules, passive-loss limits and prior-year carryovers may change the outcome.
Step-by-step checklist
- Collect Form 1098 and closing documents.
- Trace how mortgage proceeds were used.
- Identify actual property taxes paid to the authority.
- Separate deductible points from loan fees.
- Compare Schedule A total with the standard deduction.
Reconcile the result to the actual return, notice, lender disclosure or benefit statement before signing. Preserve the source documents, calculations and proof of submission; a software interview or account screen is not a substitute for evidence.
Records to keep
Keep the filed forms and schedules together with receipts, statements, contracts, account records and correspondence that establish amount, date, ownership and purpose. For an asset, credit or carryforward that affects later years, retain the origin-year worksheet through the final disposition or use year and the applicable limitation period.
Common mistakes to avoid
- Deducting mortgage principal.
- Claiming escrow deposits before the servicer pays property tax.
- Treating repairs and homeowners insurance as itemized deductions.
Correct an issuer or agency error through the documented correction process rather than silently changing a reported amount. When the dollars are material, a notice deadline is close, or the facts involve more than one jurisdiction, obtain advice from a credentialed professional who can review the complete record.
