6 Cost Segregation Firms Florida Real Estate Owners Should Know in 2026

If you own property in Florida, you have one advantage nobody in New York or California gets. There’s no state income tax to eat into the value of an accelerated depreciation deduction. That single fact changes the math on whether a cost segregation study is worth commissioning, and it’s a big reason the state has its own cluster of specialist and national firms competing for the work.

Cost segregation reclassifies parts of your building, like flooring, cabinetry, parking lots, and certain electrical systems, into 5-, 7-, or 15-year depreciation categories instead of the standard 27.5- or 39-year schedule. That shift moves your deductions earlier, which frees up cash you can put back into your property or portfolio. Some firms handle this for your single-family and short-term rentals, others work at the scale of large commercial portfolios, and a few fold it into a broader tax consulting practice. Here are six worth knowing before you pick who runs the numbers on your property.

Best for Florida-Specific Cost Seg Studies – Florida Cost Seg

Florida Cost Seg runs engineering-based cost segregation studies tailored to Florida’s investors, CPAs, and commercial property owners, with clients spread from Miami and Palm Beach up through Tampa, Orlando, Jacksonville, and Southwest Florida. The studies reclassify your building components into 5-, 7-, and 15-year lives, accelerating your deductions and improving cash flow for short-term and vacation rentals, condos, multifamily, retail, office, and industrial properties.

Because Florida has no state income tax, accelerated and bonus depreciation retain their full federal value here rather than being partially offset by a state tax bill. That matters more in 

Florida is more than in most states, and it’s compounded by how much short-term rental activity the state has. Florida Cost Seg pairs its studies with material participation planning for short-term rental owners, which is often where you can miss real tax benefits if nobody flags it early.

The firm also handles look-back studies using Form 3115 if you never had a study done when you first bought a property and produces audit-ready reports rather than a bare spreadsheet. A free feasibility analysis lets you see the projected benefit before committing to a full study. R.E. Cost Seg powers it and is a good fit if you want a specialist who understands both the engineering side of the work and the specific tax landscape of owning property in Florida.

Best for Large-Scale National Tax Consulting – KBKG

KBKG is a national tax consulting firm built for scale, with a track record the company puts at $11 billion in tax benefits claimed for clients. It has brick-and-mortar offices in Los Angeles, New York, Atlanta, Chicago, Dallas, and Houston, and its team includes former Big Four leaders working alongside what the firm calls the country’s leading experts in the space.

You’re not limited to real estate services here. KBKG works with you if you’re a business owner or CPA looking across a broad set of tax strategies and incentives created by Congress, and it says it has built up a track record over 25 years serving thousands of CPAs. The firm also uses proprietary technology to help maximize the savings it finds.

The trade-off is scale itself. A firm built around six major-city offices and a national CPA client base isn’t built the same way as a firm working state by state. If you own a single Florida property, you may find yourself working with a team whose main practice sits somewhere else entirely.

Best for Full-Service CPA Support – Kaufman Rossin

Kaufman Rossin is a CPA firm rather than a standalone cost segregation shop, and they offer tax, audit, and advisory services under one roof. It’s independent by choice, and its pitch centers on helping you reduce risk and grow over the long term rather than chase a single deduction.

That structure makes it a good fit if you want a single firm to handle your tax filings, audits, and broader financial advisory work as well as any depreciation planning, rather than bringing in a separate specialist for each piece. The trade-off is that cost segregation isn’t the singular focus here, as it’s for a firm built specifically around engineering-based studies.

Best for International R&D and Innovation Incentives – Leyton

Leyton is an international consulting firm specializing in innovation funding, tax-related research incentives, and performance optimization for businesses, with a strong presence in markets like Germany. Its work spans national funding programs, EU funding, VAT compliance, and research tax credit claims.

This makes Leyton a better match for you if you’re a business pursuing research and innovation incentives across borders than if you’re a Florida property owner focused specifically on building depreciation. The trade-off for you is that Leyton’s core strength sits in R&D and innovation funding, not in property-specific cost segregation work.

Best for Multi-Service Tax Credit Bundling – Source Advisors

Source Advisors is a tax consultancy firm that covers a broader range of credit types than most firms on this list, including R&D tax credits, cost segregation, LIFO, energy efficiency tax credits, and sales and use tax credits. It positions itself as a trusted partner to businesses and CPAs rather than a single-service shop.

That breadth suits you if you’re a business or property owner who wants one firm to handle several categories of tax credits at once, rather than coordinating separate specialists for each. The trade-off is that cost segregation is one line among several here, not the singular focus you’d get from a firm built around it alone.

Best for Small Residential Rental Portfolios – SMF Cost Seg

SMF Cost Seg focuses specifically on short-term rentals, single-family rentals, and small multifamily properties, conducting engineering-based cost segregation studies for 1-10-unit residential rentals. The firm says its studies can save 20 to 40 percent of a building’s value through year-one tax deductions, and it offers flat-rate pricing, 24-hour proposals, virtual site visits, and IRS audit defense.

That narrow focus on small residential portfolios is exactly what makes it useful if you have a handful of rental units and don’t need a firm built for large commercial properties. The trade-off is scale in the other direction: if you have a large office, retail, or industrial portfolio, you’ll likely outgrow what a firm built around 1-10 unit residential properties is designed to handle.

What Actually Determines Your Deduction Savings

The size of your benefit from a cost segregation study depends less on which firm you pick and more on a handful of property-specific factors. Property type matters first: your fully furnished short-term rental typically has more components eligible for 5- and 7-year reclassification than a bare-bones office building, since furniture, appliances, and certain flooring and fixtures qualify for faster depreciation.

Your purchase price and building age matter too. A newer or more expensive building generally has more components worth reclassifying. However, bonus depreciation rules have changed the calculation for property placed in service in different years, so your year of purchase affects the outcome.

Material participation is the piece you can miss most often. The IRS generally treats rental activity as passive, which limits how losses offset other income, unless you meet specific material participation tests tied to hours worked in the activity. A cost segregation study that isn’t paired with attention to this rule can leave real deductions unused on paper. If you’re juggling multiple properties, keeping your financial records organized becomes just as important, and visual design in financial services can help make complex financial information easier to track and understand.

Finally, whether your property has ever had a study done affects the path forward. If you skipped a study at purchase, you can often still capture the benefit through a look-back study filed with Form 3115, rather than permanently losing the opportunity.

Which One Is Right for You

If you’re an owner working with a national CPA relationship and want tax, audit, and advisory services from a single firm, you’re a natural fit with Kaufman Rossin. If you’re a business chasing cross-border R&D incentives, you’re better served by Leyton. Source Advisors suits you if you want several credit types bundled with one firm, KBKG fits you if you’re comfortable working with a firm built for national scale, and SMF Cost Seg is the clear pick if you have a small residential rental portfolio of 1-10 units.

For you as a Florida property owner, though, the calculation is different. Florida’s lack of a state income tax means every dollar of accelerated depreciation keeps its full federal value here, and that’s exactly the environment Florida Cost Seg built its practice around. Between the free feasibility analysis, the Form 3115 look-back option, and pairing cost segregation with material participation planning for short-term rental owners, it’s the strongest fit on this list if your properties and tax exposure are specifically in Florida.
