Enhancing Partial Asset Disposition Accuracy Through Cost Segregation

Real estate owners and investors are always looking for ways to optimize depreciation and improve after-tax cash flow. One strategy that often flies under the radar is the Partial Asset Disposition (PAD) election. This option allows taxpayers to write off the remaining value of building components that have been removed, retired, or replaced.
In this article, we’ll dive into what Partial Asset Disposition is all about, how it ties in with cost segregation studies, when you should consider electing it, and how to figure out the adjusted basis of the assets you’ve disposed of.
TLDR:
A PAD lets you write off the remaining value of disposed building components.
Cost segregation makes PAD elections more accurate, defendable, and tax-efficient.
PAD must be elected in the same tax year as the disposition.
You need a reliable method to calculate the adjusted basis, ideally supported by a cost seg study.
What Is a Partial Asset Disposition (PAD) Election?
A Partial Asset Disposition (PAD) is a tax election outlined in the IRS Tangible Property Regulations that gives property owners the chance to recognize a loss when they replace or retire part of a capital asset.
Commonly Replaced Components Eligible for PAD:
Roofs
Interior drywall
Flooring
Lighting fixtures
Plumbing systems
Doors & windows
Before the Tangible Property Regulations (TPRs) were finalized back in 2014, real estate investors had to keep depreciating old building components even after they swapped them out. The PAD election changes that.
Key takeaway:
A PAD election gives you the opportunity to halt the depreciation on parts of a property that are no longer in use, allowing you to claim a loss deduction for their remaining value.
How Cost Segregation Enhances Partial Asset Dispositions
Cost segregation is a tax strategy rooted in engineering that dissects a property into its various components, assigning each one its own depreciation schedule. This detailed breakdown simplifies the process of identifying and valuing the parts of a building that are being disposed of, which is crucial for making accurate Partial Asset Disposition (PAD) elections.
Why You Should Combine PAD with Cost Segregation:
Accurate Basis Allocation: Cost seg gives a defensible number for what a component originally cost.
IRS Compliance: Cost seg studies support PADs with documentation that can withstand audits.
Increased Write-Offs: A PAD without a cost seg study may underestimate (or entirely miss) deductions.
Example Scenario: A multifamily property owner is giving their place a luxury makeover by swapping out all the original interior doors and trim. In a previous cost segregation study $32,000 was being depreciated for these elements. Now that they’re no longer in use, the owner can take advantage of a Partial Asset Disposition to write off the remaining undepreciated value—potentially saving a significant amount on taxes.
When Should You Elect a Partial Asset Disposition?
Timing is everything with PADs. You must make the PAD election in the same tax year the component is removed or retired. If you miss this window, you forfeit the deduction.
Ideal Times to Elect PAD:
During or immediately after a renovation or capital improvement
When disposing of part of a building (e.g., tearing down old walls or upgrading finishes)
If you're demolishing a portion of a structure for redevelopment
Tip: Keep detailed renovation records and consult your CPA before year-end to ensure timely election.
Calculating the Adjusted Basis of a Disposed Component
The adjusted basis is the remaining undepreciated value of the disposed asset at the time of removal.
Basic Calculation:
Determine original cost of the component (from a cost seg study or reasonable estimate).
Subtract depreciation taken on that component up to the year of disposition.
Formula:
Adjusted Basis = Original Allocated Cost – Accumulated Depreciation
If you've done a cost segregation study, this is easy, your report should list the original cost of individual components. If you haven’t, the IRS allows reasonable methods (e.g., engineering estimates or cost indexes), but those carry more audit risk.
Should You Use PAD?
Partial Asset Dispositions are a powerful but underutilized tax-saving opportunity for real estate investors. When paired with cost segregation, they allow for precise write-offs and improved cash flow, especially during renovations and property upgrades.
If you're planning a major renovation or recently completed one, talk to your tax advisor or cost segregation firm about performing a PAD analysis. Don't leave money on the table.
