At a 32.0% rate, accelerating roughly $96,364 of deductions into year one is about $30,836 that stays in your pocket now instead of trickling in over decades.
Rough estimate for education only. Real cost segregation needs an engineering-based study, and bonus depreciation rules, recapture, the mid-quarter convention, and passive-loss limits all apply. Talk to your CPA before you count on any of these numbers.
