The Tax Strategy Most Investors Miss
Cost Segregation: Accelerate Your Depreciation
Stop spreading your depreciation deduction over 27.5 or 39 years. A cost segregation study reclassifies parts of your property into 5-, 7-, and 15-year buckets โ pulling six figures of deductions into year one and sheltering your rental income (and sometimes more).

Cost segregation is an IRS-sanctioned engineering study that breaks your property into its component parts โ and depreciates each one on its real useful life instead of lumping everything into a single, slow 27.5- or 39-year schedule. The result: a much bigger deduction, much sooner.
The Default
Without a study, the IRS makes you depreciate residential rentals over 27.5 years and commercial property over 39 years โ straight-line. A $1M building generates roughly $36K a year in residential depreciation. Useful, but slow, and it ignores that your carpet, cabinets, and landscaping wear out long before the structure does.
The Reclassification
A cost-seg engineer walks the property and assigns components to their actual depreciation lives โ 5 years for flooring, fixtures, appliances, and millwork; 7 years for certain personal property; 15 years for site improvements like landscaping, fencing, and parking. Typically 20โ35% of a building's basis moves out of the long bucket.
The Outcome
Front-loaded deductions โ often $150Kโ$300K+ in year one on a single Utah property โ that can offset rental income, and (if you qualify as a real estate professional or run short-term rentals) potentially shelter W-2 or business income too. More cash in your pocket now, ready for your next deal.
THE PROCESS
How a Cost Seg Study Works
A formal study takes 4โ8 weeks from kickoff to delivery. Your CPA then plugs the report into your tax return โ either in the year of acquisition, or as a "look-back" study that recovers missed depreciation from prior years using IRS Form 3115 (no need to amend old returns).
Engage the Firm
A short feasibility conversation confirms the study will pencil out. You share basic property details โ purchase price, building type, acquisition date โ and get a fixed-fee proposal back.
Site Visit & Engineering
Engineers walk the property (or work from blueprints, photos, and closing docs for smaller deals), inventorying every component โ flooring, cabinets, HVAC, electrical, parking, landscaping, signage.
Reclassification Report
You receive a detailed report assigning each component to its IRS-defined class life โ 5, 7, 15, or 27.5/39 years โ with full documentation that holds up to audit.
Apply to Your Return
Your CPA uses the report on this year's return โ or files Form 3115 to claim missed depreciation from prior years in one lump catch-up. No amended returns needed.
A REAL UTAH EXAMPLE
$1M Multifamily, Year One
A small Salt Lake Valley fourplex purchased for $1,000,000 (with $200K of that allocated to land, leaving $800K of depreciable basis).
Without a study: $800K รท 27.5 = roughly $29K of depreciation per year, every year, for nearly three decades.
With a cost-seg study reclassifying ~25% of the basis ($200K) into short-life buckets โ and current bonus depreciation rules layered on top โ year-one depreciation can land in the $150Kโ$220K range. That's 5โ7x the default.
The deduction comparison
Illustrative example. Actual results vary by property, allocation between land and building, current bonus depreciation rate, your tax bracket, and whether you can use passive losses against active income. Always confirm numbers with your CPA.
When Cost Seg Pencils Out
Property Cost Above ~$500K
Below that, the study fee starts eating the savings. Sweet spot is $750K and up โ multifamily, commercial, larger short-term rentals.
Income to Offset
You need W-2 income, business income, or other rental income to soak up the deductions. Real estate professional status (REPS) or short-term rental treatment unlocks offsetting active income too.
Plan to Hold 3+ Years
Selling sooner triggers depreciation recapture, which can claw back some of the benefit. Hold long enough to enjoy the time value of the front-loaded deduction.
Recently Acquired or Improved
Best done in the year you buy or finish a major renovation โ but look-back studies (Form 3115) can recover missed depreciation from properties you've owned for years.
The ROI Math
Few investments give back this fast. Most studies pay for themselves before April.
A Critical Wrinkle
Bonus Depreciation: A Special Note
Cost segregation works on its own โ but for a stretch of years it was paired with bonus depreciation, which let you write off 100% of short-life assets in year one. That bonus is phasing out, and the timing matters.
The Phase-Down Schedule
Anything not eaten by bonus depreciation still accelerates over the regular 5-, 7-, or 15-year schedule โ so cost seg keeps adding value even as bonus phases out. The earlier you act, the bigger the year-one punch. Tax law also changes; Congress has restored bonus rates before, and could again. Confirm the current rate with your CPA before you plan around specific numbers.
Real Estate Professional Status (REPS)
Spend 750+ hours per year in real estate as your primary trade or business and your rental losses become non-passive โ meaning they can offset your spouse's W-2 income, your business income, anything. This is the biggest unlock for high-income households.
Short-Term Rentals (STR Loophole)
Average guest stay of 7 days or less, with material participation, takes the property out of the passive bucket entirely. Park City and St. George STRs are popular cost-seg targets for exactly this reason โ no REPS required.
ACTION PLAN
The 6-Step Cost Seg Playbook
From "is this property even a candidate?" to writing the deduction on your return.
Identify Candidate Properties
Anything you've bought, built, or substantially renovated in the last 15 years with a depreciable basis above ~$500K. Multifamily, commercial, short-term rentals, larger single-family rentals all qualify.
Confirm You Can Use the Deductions
No point creating a paper loss you can't deploy. Confirm with your CPA that you have rental income, REPS qualification, an STR, or another path to actually use the depreciation this year or carry it forward.
Get a Free Feasibility Analysis
A reputable cost-seg firm will give you a no-cost estimate showing projected reclassification percentages, year-one deduction range, and study fee โ so you can see if the ROI is worth it before committing.
Engage the Firm for the Formal Study
Sign the engagement, share your closing documents and any blueprints, schedule the site visit. Most studies wrap in 4โ8 weeks โ well in advance of tax filing if you start early.
Apply It to Your Return
Hand the report to your CPA. For current-year acquisitions it slots into Form 4562. For prior-year properties, your CPA files Form 3115 to claim the catch-up depreciation in one shot.
Repeat on the Next Property
Cost seg is repeatable. Every qualifying property you acquire is a fresh opportunity to front-load deductions โ a powerful flywheel when you're actively scaling a portfolio.
How Stodd Group Fits In
We're real estate brokers, not CPAs or tax advisors โ and we'll never pretend otherwise. But cost segregation lives at the intersection of acquisition strategy and tax planning, and that's a place we know well.
We Have a Trusted Partner
We work with a specialty cost-seg firm that handles studies for our investor clients. They've done deals from $500K duplexes up to $20M+ commercial buildings โ and we can introduce you for a no-cost feasibility analysis.
We Coordinate the Timing
When you're closing on a property, we make sure the cost-seg conversation happens early โ so the study lands in the tax year you want it, and the deduction shows up exactly when it does the most good.
We Help You Find Candidates
Not every Utah property is a cost-seg fit. We can flag the deal types that historically reclassify well โ multifamily, mixed-use, short-term rentals in the resort markets โ so you're hunting in the right pond.
Always Loop In Your CPA
This is real-money tax planning โ not a place to wing it. We coordinate directly with your accountant (or recommend one if you don't have a real estate-savvy CPA yet) so the study, your return, and your overall strategy all line up.
