Section 179 Deduction

Section 179 lets eligible taxpayers elect to deduct the cost of certain qualifying property in the year it is placed in service, subject to dollar, phaseout, business-use, and taxable-income limits.

Investor Context

What it means for real estate investors.

Real estate investors should be careful with Section 179 because not all rental or real estate property qualifies. IRS guidance distinguishes qualifying property, qualified real property, business use, and property that does not qualify.

Why It Matters

It can accelerate deductions for certain qualifying property.

For tax years beginning in 2025, IRS Publication 946 lists a $2,500,000 maximum Section 179 deduction; IRS guidance for 2026 lists $2,560,000.

Section 179 is subject to business income and other limitations.

Records To Prepare

Placed-in-service dates and invoices

Business-use percentage support

Property classification and qualified real property analysis

Taxable income and carryover records

Common Caution

Do not assume residential rental building costs qualify for Section 179. Eligibility depends on the type of property and how it is used.
