For 2026, federal Section 179 permits an election for the eligible business-use share of qualifying property placed in service during the tax year. The $2,560,000 federal maximum begins a dollar-for-dollar reduction when qualifying Section 179 property placed in service exceeds $4,090,000; more than 50% business use, the taxable-business-income limit, federal carryforward, and later recapture rules also apply. New Jersey uses separate Section 179 and depreciation-adjustment rules, so the federal and state basis, recovery, recapture, and disposition computations must be reconciled on the applicable returns.
Section 179 and bonus depreciation have separate federal eligibility, election, acquisition, placed-in-service, limitation, and recapture rules. New Jersey does not conform to the current federal 100% Section 168(k) allowance and applies separate Gross Income Tax and Corporation Business Tax adjustment mechanics.
How Does New Jersey Differ From Federal Rules on Section 179?
For Gross Income Tax purposes, current Form GIT-DEP generally limits the total New Jersey Section 179 deduction to $25,000, subject to its Liberty Zone instructions. The federal reduced-dollar limitation for property cost is calculated using that New Jersey maximum. GIT-DEP states that the Gross Income Tax computation has no business-income limitation and that an unused New Jersey deduction cannot be carried forward, carried back, or applied against another income category. Partnerships and S corporations apply the entity, NJK-1, and member rules in the current instructions; Corporation Business Tax filers use the applicable Schedule S and return rules. A larger federal Section 179 deduction can create a separate New Jersey basis and cost-recovery computation, but the excess alone does not prescribe one state method or recovery life.
Does New Jersey Allow Bonus Depreciation?
New Jersey does not conform to the current federal 100% Section 168(k) additional first-year allowance. For Gross Income Tax, current GIT-DEP retains its expressly described legacy rule allowing the federal 30% special allowance when the asset meets the federal requirements and that allowance was taken federally, while disallowing the federal 50% special allowance. Current federal 100% bonus property requires the applicable New Jersey adjustment and separate basis and recovery computation. Gross Income Tax filers use GIT-DEP and the prescribed NJ-BUS, NJ-DOP, entity, and member routes as applicable; Corporation Business Tax filers apply Schedule S and the current entity-return instructions.
Which Federal and NJ Depreciation Records and Computations Differ?
The computation uses the supported asset description and property class; acquisition, contract, and placed-in-service dates; basis and transaction costs; business-use allocation; Section 179 election; federal and NJ method, life, and depreciation; and any recapture or disposition facts. Reconcile the actual federal and New Jersey schedules and returns. These are reporting mechanics, not a purchase recommendation or a software-output guarantee.
Key Takeaway
New Jersey's current bonus-depreciation nonconformity and separate Section 179 rules can create federal-New Jersey basis and timing differences. The applicable adjustment, New Jersey cost recovery, recapture, and later disposition adjustment follow the actual asset, federal deduction, elections, business use, entity, income category, and state return rules; no equipment-purchase recommendation follows.
OBBBA update (July 2025): The One Big Beautiful Bill Act made the 100% federal Section 168(k) allowance permanent for otherwise-qualified property acquired and placed in service after January 19, 2025, and for applicable specified plants planted or grafted after that date. Under Notice 2026-11 and the existing regulations, the acquisition date for property acquired under a written binding contract is the later of contract entry, enforceability under state law, the end of all cancellation periods, and satisfaction of all contingency clauses; self-constructed property and later-acquired components have separate rules. Otherwise-qualified property acquired on or before January 19, 2025 stays on the old IRC Section 168(k)(6) schedule: 40% if placed in service in 2025, 20% if placed in service in 2026, and 0% later, subject to the applicable placed-in-service deadline and any special property rule. Thus, a property subject to a 2024 contract has a 20% 2026 rate only if the later-of acquisition test establishes a pre-January 20, 2025 acquisition and all other qualification and placed-in-service requirements are met. The 2026 federal Section 179 maximum is $2,560,000, with the phaseout beginning at $4,090,000. Current New Jersey GIT-DEP generally uses a $25,000 Section 179 maximum and does not conform to the current federal 100% bonus allowance.

Frequently Asked Questions
What is the NJ Section 179 limit?
For Gross Income Tax, current GIT-DEP generally limits New Jersey Section 179 to $25,000, subject to its Liberty Zone instructions, and calculates the reduced-dollar limitation using that maximum. GIT-DEP has no business-income limitation and does not carry an unused New Jersey deduction forward, back, or across income categories. The 2026 federal maximum is $2,560,000, with a $4,090,000 phaseout threshold, plus separate federal eligibility, business-use, taxable-income, carryforward, and recapture rules. Entity and CBT return instructions control their respective adjustments.
Does NJ allow bonus depreciation?
New Jersey does not conform to the current federal 100% Section 168(k) allowance. Current GIT-DEP separately retains its expressly described legacy 30% special-allowance route when federally taken and disallows the federal 50% allowance; CBT filers follow Schedule S and the current entity-return instructions. Federal eligibility still depends on qualified-property status, the Notice 2026-11 acquisition test, placed-in-service timing, basis, business use, elections, and transition rules.
How do I track depreciation for both federal and NJ?
Retain and reconcile the federal and New Jersey asset, basis, method, life, depreciation, recapture, and disposition records required by the applicable forms. Whether a software product produces the applicable GIT-DEP, Schedule S, entity, or owner adjustment depends on the product, module, setup, asset data, and return type; its output does not establish the New Jersey computation.
Is the OBBBA permanent bonus depreciation reflected on NJ returns?
No. Current federal bonus-depreciation treatment depends on the property's qualification, acquisition and placed-in-service dates, basis, business use, elections, and transition rules. New Jersey does not conform to that federal allowance and requires its own basis and cost-recovery computation under the applicable state rules.
