Bonus Depreciation for Real Estate Investors: Complete Guide

Bonus depreciation allows real estate investors to deduct a large portion of eligible asset costs in the first year of ownership rather than spreading them over decades. As of 2025, the One Big Beautiful Bill Act has permanently restored 100% bonus depreciation for property placed into service after January 19, 2025, reversing a phase-out that had reduced the deduction to 60% in 2024. This is one of the most significant tax changes for real estate investors in years.

What Is Bonus Depreciation?

Depreciation is one of the most powerful tax tools available to real estate investors. When you own investment property, the IRS allows you to deduct a portion of the asset’s cost each year to account for wear and tear, even while the property’s market value appreciates. For residential real estate improvements, the standard depreciation schedule is 27.5 years. Commercial properties depreciate over 39 years.

Bonus depreciation accelerates this process. Rather than spreading deductions across decades, investors can take a large percentage of eligible asset costs as a deduction in the year the property is placed into service. This front-loads the tax benefit and can significantly reduce taxable income in year one.

It is important to note that only improvements on the property can be depreciated, not the land itself. A property purchased for $300,000 with $250,000 allocated to improvements allows you to claim depreciation on the $250,000 portion, reducing taxable income accordingly.

Cost Segregation: Maximizing Bonus Depreciation

Bonus depreciation applies specifically to assets with a useful life of 20 years or less; items like appliances, cabinetry, flooring, HVAC systems, and certain building components that do not carry the full 27.5- or 39-year depreciation schedule.

A Cost Segregation Study, conducted by a CPA or specialized firm, identifies and separates these shorter-lived components from the overall building structure and assigns each to the appropriate depreciation category. This allows investors to front-load depreciation on qualifying components and take larger deductions sooner. While these studies carry a cost, they are typically worthwhile on higher-value properties where the tax savings justify the expense.

Qualified Improvement Property (QIP), such as interior upgrades to nonresidential buildings, also qualifies for bonus depreciation, adding another avenue for accelerating deductions.

The Phase-Out and Restoration: A Timeline

Bonus depreciation has gone through significant changes since its expansion under the 2017 Tax Cuts and Jobs Act, which introduced 100% bonus depreciation. The provision began phasing out in 2023:

The restoration under the One Big Beautiful Bill Act permanently eliminated the phase-out schedule. Assets must be new to the taxpayer but do not have to be brand new, a meaningful distinction for investors acquiring existing properties.

Why This Matters for Your Investment Strategy

The practical impact of bonus depreciation on real estate investing is substantial. With 100% bonus depreciation permanently in place, investors can:

• Reduce taxable income significantly in year one of ownership
• Improve cash flow by preserving capital that would otherwise go to taxes
• Make marginal deals more financially viable by improving early-year returns
• Offset active income if they qualify as a Real Estate Professional
• Free up capital for reinvestment into renovations or additional acquisitions

The Real Estate Professional designation is particularly powerful in this context. Investors who dedicate at least 750 hours per year and more than 50% of their working hours, to real estate activities can use losses from depreciation to offset active W-2 or business income rather than only passive income. This designation requires careful documentation of hours in the event of an IRS inquiry.

Additional 2025 Tax Changes Affecting Real Estate Investors

The OBBBA introduced several other provisions relevant to real estate investors alongside the bonus depreciation restoration.

QBI Deduction (20%) Made Permanent

The Qualified Business Income deduction, which allows pass-through entities including LLCs, S-corps, and sole proprietorships commonly used in real estate, to deduct up to 20% of qualified business income, has been made permanent. Eligibility depends on whether rental activity qualifies as a trade or business. Documentation of active management and business activity remains important.

SALT Deduction Cap Raised to $40,000

The cap on state and local tax (SALT) deductions increased from $10,000 to $40,000 annually through 2029. This provides meaningful relief for investors operating in high-tax states such as New York, California, and New Jersey where property taxes and state income taxes create a heavier combined burden.

Section 179 Enhanced

Section 179 expensing remains available alongside bonus depreciation, and the OBBBA increased the maximum Section 179 deduction to $2.5 million (up from $1 million), with the phase-out threshold raised to $4 million. The two provisions can be used together strategically depending on asset type and acquisition timing.

No Changes to 1031 Exchanges or Opportunity Zones

The OBBBA did not alter rules around 1031 like-kind exchanges or Opportunity Zones. Investors can continue to defer gains through 1031 swaps or potentially reduce them through Opportunity Zone investments as before.

Strategic Planning for Investors

With 100% bonus depreciation permanently restored, there are several practical steps investors should consider:

• Re-evaluate acquisition timelines. The timing of when property is placed into service matters. Year-end acquisitions can drive meaningful tax impact for the current tax year.
• Run cost segregation studies. Accelerating depreciation on building components through a cost segregation study unlocks the full benefit of bonus depreciation on a property-by-property basis.
• Coordinate with a tax advisor. Individual circumstances, entity structure, state of operation, income levels, and professional status all influence how these provisions apply. What works for one investor may not be optimal for another.
• Model the impact on deal economics. With the full deduction permanently available, deals that did not pencil out at 60% bonus depreciation in 2024 may now be financially viable. Revisit underwriting assumptions accordingly.
• Document Real Estate Professional hours. If you are approaching or maintaining this designation, diligent hour documentation is essential. The IRS requires contemporaneous records in an audit.
