Cost segregation in New Jersey is an IRS-compliant tax strategy that involves an engineering-based study of your real estate property to reclassify building components into shorter depreciation categories 5, 7, or 15 years, instead of the standard 27.5 or 39 years. This accelerates your depreciation deductions, significantly reducing federal taxable income. Given New Jersey's high property values and tax environment, cost segregation can be especially impactful for local investors.
