Analytical Proof & Invariants

Machine Precision
Governing Mathematical Formula:
Realized Gain = Net Sales Price - Adjusted Basis | Tax Deferred = (Cap Gain × Rate) + (Recapture × 25%)

Step-by-Step Mathematical Derivation

1
Adjusted Basis Calculation

Adjusted Basis = Original Basis - Accumulated Depreciation. For example: $650,000 - $180,000 = $470,000.

2
Realized Gain Decomposition

Total Gain = Sales Price - Adjusted Basis = $1,200,000 - $470,000 = $730,000. Composed of $180,000 depreciation recapture (taxed at 25%) + $550,000 capital gain (taxed at 20% federal + 3.8% NIIT + ~3% state).

3
Full Deferral Rules

To achieve 100% tax deferral with zero taxable boot, the replacement property must have equal or greater purchase price AND equal or greater debt/equity.
