What Gets Reclassified

A cost segregation study identifies building components that can be depreciated over 5, 7, or 15 years instead of the standard 27.5 or 39 years. In Wilmington, typical reclassification rates are 25-38% of building value.

The math: A $240,000 property with 70% building value and 30% reclassification yields ~$18,648 in Year 1 federal tax savings at the 37% bracket — significantly more ROI than traditional studies costing $5,000-$10,000+.

Housing Stock Advantage

With a median build year of 1980, Wilmington's housing stock has identifiable components (HVAC, electrical, plumbing, landscaping) that are strong candidates for accelerated depreciation.

Non-Conformity — DE decouples from bonus depreciation
Delaware Bonus Depreciation Conformity

Delaware does NOT conform to federal bonus depreciation under IRC Section 168(k). The state requires investors to add back federal bonus depreciation and instead use standard MACRS depreciation schedules for state tax purposes. This means your federal cost seg benefits are immediate, but state-level depreciation is spread over the standard MACRS recovery periods (5, 7, 15, or 39 years).

What This Means for Wilmington Investors: Delaware's non-conformity creates a timing difference, not a permanent loss. Your federal bonus depreciation is unaffected — you still get 100% first-year deductions at the federal level. For state purposes, you depreciate reclassified assets over their MACRS lives. The state benefit is smaller in Year 1 but accumulates over time. At a 6.6% top state rate, the total state savings are modest regardless of timing.

Federal vs. DE Depreciation Timeline
PeriodFederal TreatmentDE State Treatment
Year 1100% bonus depreciationStandard MACRS depreciation only (no bonus)
Years 2+Standard MACRS schedulesContinued MACRS depreciation (catching up over recovery period)
Section 179 Expensing
State ConformityLimited

Delaware generally follows federal Section 179 expensing but may impose its own dollar limitations. For most residential cost segregation studies, bonus depreciation (not Section 179) is the primary mechanism, making the non-conformity issue more relevant than Section 179 differences.

Key Takeaway

A $340K property with a $244,800 depreciable basis and 28% cost seg reclassification yields ~$25,370 in federal tax savings in Year 1. State savings are spread over MACRS recovery periods due to non-conformity, adding ~$1,200-$1,800 in state savings in Year 1 via standard depreciation. Total Year 1 savings: ~$26,570-$27,170.

Bottom Line

Delaware investors receive full federal bonus depreciation benefits immediately but must use standard MACRS schedules for state tax purposes. At a 6.6% top state rate, the Year 1 state impact is modest. Focus on the federal savings (37% bracket) as the primary driver — the state timing difference is a planning nuance, not a deal-breaker.

Property Tax Details

New Castle County's effective property tax rate of ~0.55% is among the lowest in the Mid-Atlantic corridor. Assessments are based on older base-year valuations, keeping effective rates well below what market values would suggest. This low tax burden is a major cash flow advantage.

Assessment Methodology
MethodAssessed value (often based on older base-year valuations, well below market)
Reassessment CycleVaries by county — many counties have not reassessed in decades
Assessment BodyCounty Assessment Office
Appeal WindowVaries by county — typically 30 days from notice
Appeal Success Likelihood
Low
LowModerateGoodVery High

Delaware's property tax assessments are often based on decades-old base-year valuations, meaning assessed values are frequently well below current market value. This keeps effective tax rates extremely low. Because assessments are already favorable, appeal success rates are lower — there is less room for reduction when assessments already lag market values significantly.
