Here’s a detailed, original article about tax write-offs when buying a house in the U.S., structured as per your request:

Article Summary

Understanding tax write-offs when buying a house is critical for homeowners, real estate investors, and small business owners in the U.S. These deductions can significantly reduce taxable income, improve cash flow, and create long-term financial benefits. However, strict IRS rules govern eligibility, substantiation, and proper documentation. Key challenges include distinguishing between deductible and non-deductible expenses, maintaining accurate records, and navigating recent tax law changes (e.g., the Tax Cuts and Jobs Act of 2017). Homebuyers must act quickly—mortgage interest, property taxes, and other deductions must be claimed by the annual tax filing deadline (typically April 15th for individuals, or October 15th with an extension). Missing these deductions could mean leaving thousands of dollars in potential savings on the table.

What This Means for You

Immediate Action: Gather all closing documents, mortgage interest statements (Form 1098), and property tax receipts from the past year. The IRS requires detailed records to substantiate deductions.
Financial Risks: Incorrectly claiming deductions can trigger IRS audits, accuracy-related penalties (20% of underpaid tax), and interest charges. In cases of fraud, criminal penalties may apply.
Maximizing Benefits: Properly claiming deductions can lower taxable income, increase refunds, and improve long-term affordability of homeownership. Strategic planning (e.g., timing property tax payments) can further optimize savings.
Long-Term Strategy: Implement a system to track mortgage interest, property taxes, and home office expenses annually. Consult a tax professional to stay updated on changing laws and maximize future deductions.

What is a Tax Write-Off When Buying a House?

Under U.S. tax law (IRC § 163(h)), a tax write-off (or deduction) reduces taxable income for eligible homeownership expenses. Key terms:

Deductible Expense: A cost the IRS allows you to subtract from gross income (e.g., mortgage interest).
Itemized Deductions: Specific expenses claimed instead of the standard deduction.
Capital Improvement: Home upgrades that add value (e.g., a new roof), which may qualify for depreciation or capital gains exclusion later.

General Principles of Deductibility

The IRS permits deductions for expenses that are:

Ordinary and Necessary: Common for homeowners (e.g., property taxes).
Directly Tied to Homeownership: Personal expenses (e.g., utilities) generally don’t qualify unless used for business.

For mixed-use expenses (e.g., a home office), only the business portion is deductible.

Standard Deduction vs. Itemized Deductions

In 2024, the standard deduction is:

$14,600 (single filers)
$29,200 (married filing jointly)

Itemizing is only beneficial if total deductions exceed these amounts. Common itemized deductions for homeowners include:

Mortgage interest (up to $750,000 in loan debt)
State and local taxes (SALT), capped at $10,000
Points paid at closing

Types of Tax Write-Offs When Buying a House

1. Mortgage Interest Deduction (IRC § 163(h))

Eligibility: Interest on mortgages up to $750,000 (or $1M for loans pre-December 2017). Must be your primary or secondary home.

How to Claim: Use Form 1098 from your lender and report on Schedule A.

2. Property Tax Deduction (IRC § 164)

Eligibility: State/local property taxes, up to the $10,000 SALT cap.

Note: Transfer taxes and HOA fees are not deductible.

3. Points (IRC § 461(g))

Eligibility: Points paid to lower your mortgage rate are deductible over the loan term (or fully in the year paid if for your primary home).

4. Home Office Deduction (IRC § 280A)

Eligibility: Only if you use part of your home exclusively and regularly for business. Calculate using the simplified ($5/sq ft) or actual expense method.

5. Capital Improvements

While not immediately deductible, improvements (e.g., a new HVAC system) can reduce capital gains when selling.

Key Business Provisions

Real estate investors and small business owners may also qualify for:

Depreciation: Deduct the cost of rental property over 27.5 years (residential) or 39 years (commercial).
Pass-Through Deduction (IRC § 199A): Up to 20% deduction on qualified business income from rental properties.

Record-Keeping Requirements

The IRS requires:

Form 1098 (mortgage interest)
Property tax receipts
Closing disclosure (Form HUD-1)
Records of home improvements

Keep documents for 3 years after filing or 7 years if claiming depreciation.

The IRS Audit Process

Initial Contact: IRS sends a letter (never email) requesting documentation.
Review: Provide receipts, bank statements, or appraisals.
Penalties: If disallowed, you’ll owe back taxes plus penalties (20–40%).

Choosing a Tax Professional

Look for:

A CPA or Enrolled Agent with real estate expertise
Familiarity with IRS audits and appeals
Transparent fee structure
