Withum Review (2026)
Pricing, methodology, audit defense, and where this provider fits.
Editorial note: Cost Segregation Reviews is operated by Cost Seg Smart, which appears as one option among many on this site, including in this review. Public-facing data only — pricing, methodology, and credentials reflect what Withum publishes on its own site. Reviewed September 2026.
Withum's cost segregation process — Identify, Segregate, Reclassify — reallocates personal-property and land-improvement assets into MACRS 5-, 7-, and 15-year categories under §1245 and §1250, the same classification rules set by Rev. Proc. 87-56 that any engineering-based provider follows. Withum is a Princeton, New Jersey-headquartered nationwide CPA firm, and its service page publishes a specific reallocation-percentage table by property type — for example, 20%–60% for light-to-heavy manufacturing and 25%–50% for gas stations and convenience stores — which is more quantitatively specific than most CPA-firm cost segregation pages. Cost Seg Smart publishes a $2,495 starting price for industrial/warehouse properties under $1 million, by comparison, rather than a percentage range with no attached fee.

Pricing detail
Not published as a dollar fee. Withum offers a complimentary feasibility analysis and price estimate rather than a listed rate.
Pricing reflects what the firm publishes as of September 2026. Withum's site substitutes a reallocation-percentage table for a price table — useful for gauging potential benefit, not for comparing study fees across providers. For context on typical rates, see our guide to how much a cost segregation study should cost.
Methodology and process
Withum names its process Identify, Segregate, Reclassify: identifying personal property and land-improvement assets inside a building's cost basis, then reclassifying them into MACRS shorter-life categories. Its service page publishes a table titled “Potential Reallocation of Costs to Shorter-Lived Property” with ranges by property type — apartments 10%–35%, hotels/resorts 15%–50%, medical offices 20%–40%, restaurants 15%–30%, retail/shopping centers 15%–40%, light-to-heavy manufacturing 20%–60%, tenant improvements 10%–50%, warehouse/distribution 5%–30%, and gas stations/convenience stores 25%–50%. These are the firm's own published estimates, not a guarantee for any specific property.
Property-type fit
Withum's published property list spans apartments, hotels/resorts, medical offices, restaurants, manufacturing, tenant improvements, and gas stations/convenience stores — a commercial and hospitality focus. Single-family residential and short-term rental are not listed; see our STR rankings for that category.
Audit defense
Audit-defense terms — a stated guarantee, follow-up support, or IRS-representation scope — are not published on Withum's cost segregation page. The reallocation-percentage table is a planning tool, not a documentation or defense commitment.
Pros
- Publishes a specific reallocation-percentage table by property type — more quantitatively transparent than most CPA-firm cost segregation pages.
- Offers a complimentary feasibility analysis and price estimate before engagement.
- Names a clear three-step process (Identify, Segregate, Reclassify) rather than only general marketing language.
Cons
- Dollar pricing is not published — only percentage ranges and a free estimate offer.
- Turnaround time, site-visit policy, and audit-defense terms are not published.
- No published single-family residential or short-term rental offering.
Verdict — who this is for
Withum fits commercial and hospitality property owners who want to see a published reallocation-percentage range for their property type before requesting a feasibility analysis, particularly those already working with a nationwide CPA firm. It does not publish a fee, so it is not the right comparison point for an investor prioritizing a fixed rate card — see the full 27-provider table for those.
