Section 179 allows businesses to immediately deduct the cost of qualifying equipment and property rather than depreciating it over several years. However, New Jersey caps the Section 179 deduction at $35,000 (2025) compared to the federal limit of $1,250,000, and NJ does not conform to federal bonus depreciation at all. This means NJ business owners who claim large federal depreciation deductions must track separate state depreciation schedules. Greg Monaco, CPA builds this dual tracking into every NJ business client's bookkeeping and tax preparation.
Section 179 and bonus depreciation are powerful tools for accelerating deductions. But NJ doesn’t fully conform to the federal rules.
How Does New Jersey Differ From Federal Rules on Section 179?
NJ allows a Section 179 deduction capped at $35,000 (2025). Any federal Section 179 above NJ’s cap must be depreciated over the asset’s useful life for NJ purposes.
Does New Jersey Allow Bonus Depreciation?
NJ does not conform to federal bonus depreciation. Assets must be depreciated over normal useful lives for NJ purposes, creating an NJ addback in the year you claim bonus depreciation federally.
What Are the Tax Planning Implications of NJ’s Depreciation Rules?
NJ business owners need to track depreciation schedules for both federal and state purposes. This is one more reason clean bookkeeping and proper fixed asset tracking are essential. Industries with significant equipment purchases, like photographers, construction businesses, and tattoo shops, need to plan purchases with both federal and NJ depreciation rules in mind.
Key Takeaway
NJ's non-conformity with federal bonus depreciation and its lower Section 179 cap create a significant difference between your federal and NJ tax returns. Any federal Section 179 above $35,000 must be depreciated over the asset's useful life for NJ purposes, creating an NJ addback in the deduction year and NJ-specific depreciation deductions in future years. Plan equipment purchases with both jurisdictions in mind.
OBBBA update (July 2025): The One Big Beautiful Bill Act made 100% bonus depreciation permanent for property placed in service after January 19, 2025, reversing the TCJA phase-down that would have reduced the rate to 20% in 2026 and 0% in 2027. The federal Section 179 limit for 2026 is $2,560,000. NJ still does not conform to federal bonus depreciation and caps Section 179 at $25,000, so the gap between federal and NJ depreciation is now even wider with permanent 100% federal bonus depreciation.

## Frequently Asked Questions
What is the NJ Section 179 limit?
New Jersey caps the Section 179 deduction at $25,000 for 2026, significantly lower than the federal limit of $2,560,000. Any federal Section 179 deduction above the NJ cap must be depreciated over the asset's normal useful life for NJ purposes, creating an addback on your NJ return in the deduction year.
Does NJ allow bonus depreciation?
No. New Jersey does not conform to federal bonus depreciation at all. Assets that are 100% deductible federally under bonus depreciation must be depreciated over their normal useful life for NJ purposes. This creates a significant difference between your federal and NJ tax returns that requires separate depreciation schedules.
How do I track depreciation for both federal and NJ?
NJ business owners must maintain two separate depreciation schedules: one following federal rules (including Section 179 and bonus depreciation) and one following NJ rules (with the lower Section 179 cap and no bonus depreciation). Your CPA or tax software should generate both schedules and calculate the NJ addback automatically each year.
Is the OBBBA permanent bonus depreciation reflected on NJ returns?
No. The One Big Beautiful Bill Act made 100% federal bonus depreciation permanent for property placed in service after January 19, 2025. However, NJ still does not conform to federal bonus depreciation, so the gap between federal and NJ depreciation treatment is now wider than ever. NJ businesses must continue depreciating these assets over their full useful life on the NJ return.
