Bonus Depreciation in 2025 for Connecticut Business Owners
“If a window of opportunity appears, don’t pull down the shade.” -Tom Peters
Bonus Depreciation 2025: Quick Answers
- 100 percent Bonus Depreciation is now permanent under the One Big Beautiful Bill Act (OBBBA).
- Assets must be placed in service after January 19, 2025, with contracts signed on or after that date.
- Used equipment still qualifies if it wasn’t previously used in your business or bought from a related party.
- For buildings and improvements, consider a cost segregation study to carve out shorter-life assets and fully expense them this year.

Let me start off with a hypothetical: Let’s say, earlier this year, you bought a new POS system for $95K and rolled out $50K in leasehold improvements to accommodate it.
If you signed the contract and installed it after January 19th? You can deduct the full $145K in 2025. And if you’re in the top tax bracket, that could mean $50K+ in immediate tax savings.
How?
The One Big Beautiful Bill Act (OBBBA).
And it means more opportunities for you to invest in the things that grow your Connecticut business. The key is understanding what qualifies and how to structure your purchases to maximize the benefit. Let me explain…
Bonus Depreciation 2025: How it Works
The One Big Beautiful Bill Act (OBBBA) permanently reinstated 100 percent bonus depreciation for qualified property placed in service on or after January 19, 2025. But only if the binding contract to acquire the asset was also signed on or after that date.
And that “contract date” distinction could mean the difference between writing off 40 percent of an asset’s cost… or 100 percent of it in the current year.
Let’s go back to our POS system example. If you placed it in service back in early January (before January 19th), and you had already signed the deal in December, then you’re only allowed 40 percent bonus depreciation, coming out to about $58K in deductions.
But if you signed the contract after January 19 and installed it after that, too, you’re eligible to deduct the full 100 percent ($145K) in 2025.
(However, Connecticut does not conform to the federal treatment of bonus depreciation, so there will be a smaller state deduction. Other states may or may not conform to OBBBA or bonus depreciation, so make sure to review your state’s tax treatment.)
Bonus Depreciation 2025: What Qualifies?
You can fully expense almost anything with a recovery period of 20 years or less, including:
- Machinery and manufacturing equipment
- Office furniture, fixtures, and computers
- Technology infrastructure (owned, not leased SaaS)
- Vehicles (over 6,000 lbs.)
- Interior renovations in nonresidential buildings
- 15-year assets like parking lots, paving, lighting, and landscaping
And yes, used assets still qualify, as long as:
- You didn’t use it before for your business
- You bought it from an unrelated seller
- It hasn’t already been depreciated in your business
And if you’re still unsure? We can help you categorize your assets correctly and plan for purchases coming down the pipe.
What if I Bought an Asset Before January 19, 2025?
If you signed the contract or placed an asset in service before January 19, you’ll fall under the old rules. Which means you can likely deduct only 40 percent of the cost up front. But there are still options to boost your deduction:
- Do a cost segregation study: You might move parts of the purchase into shorter-life buckets (5-, 7-, or 15-year) and still get favorable treatment. For example, if it’s a building or renovation, we can break out parts of it (like lighting, fixtures, flooring) that may qualify for full 100 percent depreciation even if the overall project doesn’t. A cost segregation study may still be advisable even if the building was bought after January 19th.
- Use Section 179 expensing instead: For smaller purchases, or if you’re in a state that doesn’t follow federal bonus rules, Section 179 might let you write off the full amount anyway.
Bonus Depreciation 2025: What You Should Be Doing Right Now
If you’re eyeing any significant purchases this fall (or even in Q4), here’s your tax-smart checklist:
- Get a cost segregation study for buildings, renovations, or tenant improvements.
- Talk to your CPA (hi, that’s me) before you buy, not after the deal closes.
- Review your depreciation methods. Consider Form 3115 if you need to make a change or catch up on prior-year depreciation.
- Run cash flow projections with bonus depreciation in mind. Those deductions affect quarterly tax estimates and might free up capital you didn’t think you had.
FAQ
“I’m doing a full renovation of my office this fall. Does any of that qualify for bonus depreciation?”
Absolutely. Especially if the work includes interior buildouts in a nonresidential building. That falls under Qualified Improvement Property (QIP), which is depreciable over 15 years and fully eligible for 100 percent bonus.
Examples include:
- Non-structural walls
- Lighting
- Flooring
- Ceilings
(And if you’re not sure what’s QIP and what isn’t, we’ll review your contractor estimates.)
“I bought a building a few years ago. Can I still get bonus depreciation for parts of it now?”
Yes. You’ll need to do a cost segregation study to find out which components qualify for retroactive 100 percent bonus depreciation under the new OBBBA rules. Then you’d file Form 3115 to make an automatic accounting method change and catch up all that missed depreciation in your current tax year (a process we’re glad to assist with).
“Should I use Section 179 or bonus depreciation for my new purchases this year?”
In many cases, you can use both. We’ll help you model both options to see which mix gives you the best cash flow and tax positioning.
“Does this apply to vehicles too?”
Yes, but with some caveats. Heavy SUVs, pickups, or work vans generally qualify for full bonus depreciation. But if it’s under 6,000 lbs, the luxury auto limits kick in and the amount you can deduct is capped.
“How does this affect my quarterly estimated taxes and cash flow?”
A large bonus depreciation deduction can dramatically reduce your tax liability for the year, sometimes even creating a net operating loss (NOL). That affects your estimated payments and your cash reserves (and may even open up refund opportunities).
We can use your asset schedule to run projections, update your tax plan mid-year, and make sure your estimated payments stay aligned with your real liability.
