Cost segregation services in New Jersey, with the state half handled.
A cost segregation study moves part of your building into 5, 7 and 15-year property.
Under current federal rules a large share of that can be deducted in year one. New Jersey allows almost none of it, which means one study produces two very different sets of numbers, and somebody has to reconcile them every year until you sell.
Why MACRS depreciation feels so small to NJ property owners.
Residential rental property depreciates over 27.5 years. Commercial runs 39. Spread a purchase across that and the annual write-off is thin while your tax bill is not.
An engineering study will reclassify the components that do not belong on that depreciation schedule. Flooring, cabinetry, dedicated electrical, site improvements and landscaping carry much shorter recovery periods, and they often make up a meaningful share of the basis.
The IRS publishes a Cost Segregation Audit Techniques Guide describing what a defensible study looks like. Studies built to that standard hold up. Rules-of-thumb and spreadsheet estimates are what draw scrutiny.
Bonus depreciation is back, and cost segregation studies got stronger.
The One Big Beautiful Bill Act restored 100% bonus depreciation for property acquired after January 19, 2025, and made it permanent rather than phasing it down again.
For anything a study reclassifies into a recovery period of 20 years or less, that means the full amount is deductible in the first year. It is the strongest the federal side of this strategy has been since 2022.
Cost segregation in New Jersey: where the first-year tax savings stop.
This is the part national cost segregation firms leave out of their New Jersey pages, and there are a lot of those pages.
| Federal | New Jersey | |
|---|---|---|
| Bonus depreciation | 100%, permanent | Disallowed since 2002 for CBT, 2004 for gross income tax |
| Section 179 | $2,560,000 for 2026 | $25,000, and no carryforward of the unused part |
| Where it is tracked | Form 4562 | Form GIT-DEP, every year until disposition |
Two consequences follow. Your state tax liability is higher than the federal picture suggests in the year of the study, because New Jersey does not conform to federal depreciation rules, and your New Jersey basis stops matching your federal basis from that point on.
That second one is what bites later. New Jersey computes the gain on the sale off its own basis, so skipped adjustments turn into a wrong number at closing.
Which property types cost segregation studies suit.
Any income-producing real property with enough depreciable basis is a candidate, and some property types carry far more short-life content than others.
| Property type | Why it reclassifies well |
|---|---|
| Multifamily and apartments | Heavy personal property: appliances, cabinetry, flooring, dedicated circuits |
| Commercial real estate and retail | Tenant improvements, signage, specialty lighting, parking and site work |
| Short-term rentals | Furnishings and finishes, plus the passive activity exception that lets you use the loss |
| Mixed-use and medical | Specialized build-out and equipment hookups well beyond a plain shell |
The asset has to be placed in service before anything is deductible, so an acquisition closing in December and a renovation finishing in February fall in different tax years.
Is cost seg worth it on your property type?
Three questions settle it, and they get answered before anyone spends money on a study.
- Is the depreciable basis large enough that the federal benefit clears the engineering fee by a comfortable margin?
- Can you actually use the loss this year, or does it sit suspended? Real estate professional status or the short-term rental exception is usually what decides it.
- How long are you holding? A short hold means recapture arrives before the deferral has earned much, unless a 1031 exchange is part of the plan.
Simon runs those numbers first and says so plainly when the answer is no. Talking a client out of a study is a normal outcome.
Look-back studies cut the tax bills on properties you already own.
Owned the property for a while and never did this? A look-back study still works.
Form 3115 changes your method of accounting and catches up all the missed depreciation in the current tax year. No amended returns, and no limit on how far back the property goes. It is the cheapest tax strategy on this page for anyone who has owned a building for years.
Which New Jersey property owners this suits.
Real estate owners with rental, mixed-use or commercial property in New Jersey and enough basis to justify a cost segregation service, plus investors pairing one with an exchange on a replacement property. Accelerating depreciation deductions is what increases cash flow, and the federal and state treatment has to be run together.
Simon Klein has run this play for many of the 250-plus real estate investors he has worked with, and he handles the New Jersey adjustment as part of the engagement rather than leaving it for whoever files next year.
Questions Simon answers fast.
- How much does a cost segregation study cost?
- Engineering firms quote a fixed fee that scales with the size and complexity of the building, not a percentage of your savings. Simon runs the benefit calculation before you commission anything, and tells you when the fee will not clear the return by a healthy margin.
- Is cost segregation worth it on my property?
- It depends on your basis, how long you plan to hold, and whether you can actually use the losses this year. A large deduction that lands in a suspended passive bucket does nothing for your cash flow.
- Does New Jersey allow bonus depreciation?
- No. New Jersey decoupled from federal bonus depreciation in 2002 for corporation business tax and in 2004 for gross income tax. The federal deduction is real, the New Jersey one is not, and the difference is tracked on Form GIT-DEP.
- Can I claim deductions I missed in earlier years?
- Yes, through a Form 3115 change of accounting method. It catches up prior-year depreciation in the current year without amending old returns, which is usually the cleaner route.
- What happens to the deductions when I sell?
- Depreciation recapture applies, and the short-life components recapture as ordinary income rather than at the 25% rate. Simon models this up front and pairs the study with a 1031 exchange when it makes sense.
- Can I claim the losses if I have a W-2 job?
- Only if you clear the passive activity rules, which usually means real estate professional status or the short-term rental exception. This gets evaluated before a study is commissioned, not after.
