This simulator, interactive financial models, and multi-asset tax strategy guide are provided strictly for educational and illustrative simulation purposes. They do not constitute formal tax, legal, financial, or accounting advice. Real estate depreciation schedules, Section 1031 like-kind exchange qualification, and depreciation recapture liabilities (under IRC §§ 168(k), 1031, 1245, 1250, and Treas. Reg. § 1.168(i)-6) are complex statutory provisions governed by individual taxpayer circumstances and state-level tax conformity. Individual state tax jurisdictions may decouple from federal bonus depreciation schedules. Curtis Waters and Entrepreneurs Report are not licensed CPAs, tax attorneys, or Qualified Intermediaries. Always consult a licensed Certified Public Accountant (CPA), qualified tax attorney, and bonded Qualified Intermediary (QI) before structuring transactions or filing IRS tax returns.

IRC § 168(k) Engineering Breakdown
• Segregated Short-Life Property: $276,000 (5-Yr Personal: $180,000 + 15-Yr Land Imprv: $96,000)
• Year 1 Bonus Write-Off ($165,600 Proof): $165,600 ($276,000 × 60% Bonus Rate).
*Clarification: Bonus depreciation applies strictly to the 23% segregated personal/land improvement property, not the 27.5-year building structure ($924,000).
• Remaining Year 1 MACRS Recovery: $49,918 (5-Yr MACRS: $14,400 + 15-Yr MACRS: $1,920 + 27.5-Yr Structural: $33,598)
• Total Year 1 Deduction ($215,518 Proof): $215,518 ($165,600 Bonus + $49,918 MACRS)
• Year 1 Cash Tax Savings ($90,518 Proof): $90,518 ($215,518 × 42.0% Combined Marginal Ordinary Rate: 37% Fed + 5% State).
*Clarification: Depreciation deductions directly offset ordinary income (37% Fed + State). Capital gains tax (20%) and NIIT (3.8%) do NOT apply to ordinary depreciation write-offs.
Statutory Authorities, Audit Considerations & Practical Realities
Essential statutory framework, audit defenses, and operational rules governing Cost Segregation and Section 1031 transactions.
IRC & Treasury Regs
IRC § 1031(b)
The calculator model assumes 100% tax deferral based on zero cash boot pocketed and zero net debt relief. In practice, receiving non-like-kind property, pocketing escrow funds, or having replacement debt lower than relinquished debt triggers taxable gain recognition up to the total realized gain.
IRC §§ 1245 / 1250
Accelerated depreciation on 5-year and 15-year components is classified as Section 1245 personal property and is recaptured at ordinary income rates (up to 37% + NIIT + state). Section 1250 unrecaptured depreciation on 27.5-year real property is capped at 25% federal.
Treas. Reg. § 1.168(i)-6
Applying cost segregation a second time on replacement property is fully permitted under Treasury Regulations, but applies strictly to the Excess Basis (the step-up above carryover). The carryover basis continues its original straight-line schedule without new bonus write-offs.
IRC §§ 1411 / 469(c)(7)
The 3.8% Net Investment Income Tax applies to rental income, recapture, and capital gains above MAGI thresholds ($200k single / $250k MFJ). Taxpayers qualifying for Real Estate Professional Status (REPS) with Material Participation can reclassify income as active, shielding it from NIIT.
State Statutes
Over 20 states decouple from federal bonus depreciation (e.g. CA, NY, NJ, PA, IL, GA, NC). Decoupled states require taxpayers to add back bonus depreciation on their state returns and recover it over 5, 15, or 27.5 years via standard state MACRS.
IRC § 1031(a)(3)
You have exactly 45 calendar days to formally identify replacement properties (under the 3-Property Rule or 200% Rule) and 180 calendar days to complete acquisition and close escrow. These are strict statutory deadlines that cannot be extended for weekends or holidays.
Treas. Reg. § 1.1031(k)-1(g)(4)
Under the Constructive Receipt Doctrine, the investor, their attorney, CPA, or real estate agent cannot touch, hold, or escrow sale proceeds. Funds must flow directly to a bonded, independent Qualified Intermediary (QI) into a qualified escrow account before closing.
IRS ATG Standards
IRS-defensible engineering Cost Segregation studies typically cost $3,500 to $7,500 for commercial and multi-family assets, while standard QI exchange fees range from $1,200 to $2,500. On a $1.5M acquisition yielding $90,000+ in Year 1 tax cash savings, ROI exceeds 20x.
