New Jersey Cost Segregation: Depreciation and 2026 Loss Rules
By AE Tax Advisors · Published 2026-08-11 · Updated November 8, 2026.
New Jersey's state result can differ substantially from a federal cost segregation projection. Determine the owner's tax system, depreciation adjustments and income-category treatment before estimating a current benefit.
Build the New Jersey depreciation schedule
New Jersey decouples from specified federal depreciation provisions. Use the applicable GIT-DEP instructions for gross income tax or the relevant corporation business tax requirements. Reconcile each asset's basis, prior adjustments and current depreciation.
Do not assume that subtracting federal bonus alone always completes the calculation. Prior reporting and the state's adjustment rules can affect the available basis and deduction.
Separate wages from business categories
The gross income tax generally prevents a loss in one category from simply offsetting another category. Federal real estate professional status does not remove that state structure. A rental loss is not automatically a New Jersey deduction against wages.
Review the alternative business calculation
New Jersey also provides an alternative business calculation involving specified business categories, including rents, business profits, partnership income and S corporation income. It has its own computation and loss carryforward rules. It should not be omitted from an analysis of whether business losses have any state value.
For tax years beginning in 2026, P.L. 2026, chapter 22 changes the allowable business-increment percentage: 50% for gross income of $500,000 or less, 25% above $500,000 through $1 million, and no adjustment above $1 million. Apply the statutory gross-income measure and complete calculation; these percentages are not blanket deduction rates on every rental loss.
Include entity elections and the exit
BAIT eligibility, tax base and owner credits depend on the entity and members. Review the election separately from depreciation. On a later sale, use the required state basis and adjustment history, not an assumed federal figure.
