costsegworthit.com is a free informational decision tool operated by Cost Seg Smart LLC. It estimates whether a cost segregation study would be financially worthwhile for a given property based on the inputs you provide.
The calculator output is an estimate for educational purposes only. It is not tax, legal, accounting, or financial advice and does not create a client relationship. Tax law is complex and depends on facts the calculator cannot capture (state taxes, AMT, NIIT, passive-activity rules, your full return, your specific basis allocation, recapture mechanics, etc.). Consult a qualified CPA or tax attorney before acting on any output from this tool.
The savings ranges shown are planning midpoints based on standard assumptions: 25% of building basis reclassified to 5/7/15-year property, 80% land/improvement allocation, current bonus depreciation phase-down rates. Real engineered studies vary based on property characteristics, condition, and location. We make no representation that the figures match what an actual engineering-based study would produce or what your CPA would file.
This site is operated by Cost Seg Smart LLC, a cost segregation provider. CTAs on this page link to costsegsmart.com, which sells cost segregation studies. We have an economic interest in those clicks. The decision tool is honest — it returns NO when the math is genuinely bad — but you should know our incentive structure.
To the maximum extent permitted by law, Cost Seg Smart LLC, its affiliates, officers, and contributors are not liable for any indirect, incidental, special, or consequential damages arising from your use of this tool, including but not limited to lost tax savings, IRS penalties, or professional fees.
