Last updated: November 12, 2026

The best cost segregation firms in Nevada for 2027 are Engineered Tax Services, Haynie & Company and KBKG, followed by Cost Seg Smart, R.E. Cost Seg and Source Advisors. Engineered Tax Services leads for a Las Vegas office that also handles 1031 work, Haynie & Company for a Las Vegas CPA office, and KBKG for national depth.

Nevada investors own Las Vegas single-family rentals and apartments, Reno industrial buildings near the Tahoe-Reno Industrial Center, and Lake Tahoe vacation homes. The One Big Beautiful Bill Act made 100% bonus depreciation permanent for qualifying property acquired after January 19, 2025, so reclassified components can often be deducted in the first year on the federal return.

Nevada has no state personal or corporate income tax, so there is no state addback to worry about. The benefit of a study is almost entirely federal, which makes Nevada one of the simplest states for cost segregation. Owners who live or file in other states should check those states’ rules.
