Estimated depreciable basis after land
FREE 2026 COST SEG CALCULATOR
Reviewed August 17, 2026 · Updated for current federal bonus-depreciation guidance
See the potential numbers before ordering a study.
Our free calculator estimates the portion of depreciable basis that may move into shorter recovery periods, the potential Year 1 federal tax effect, the estimated study fee, net first-year benefit and return on the fee.
- ✓ No study work before payment
- ✓ CPA-ready final report
- ✓ California statewide
WHY IT MATTERS
Move eligible basis into faster recovery periods.
The calculator assumes qualifying 5, 7 and 15-year property is eligible for 100% federal bonus depreciation when the acquisition and placed-in-service dates meet current federal rules. It is a preliminary screen—not an engineering takeoff, tax opinion or guarantee.
Plain English: you are not creating a new deduction. You are identifying when supported pieces of the property may be depreciated.

This is a timing illustration, not guaranteed permanent tax savings. California commonly requires a separate depreciation schedule because it generally does not conform to federal bonus depreciation.

STRAIGHT ANSWERS
Frequently asked questions.
Does the calculator require my contact information?+
No. The current preliminary calculator displays the estimate immediately without requiring a form submission.
Does the estimate include California income-tax savings?+
No. It shows a federal illustration. California generally requires a separate depreciation schedule because it does not conform to federal bonus depreciation.
Is the free estimate a completed study?+
No. It is an illustrative screen using the facts you provide. No engineering takeoff, professional certification or tax opinion is included. Technical work begins only after a signed and paid engagement.
Does my CPA need to approve the study first?+
No. It is smart to ask whether you can currently use additional depreciation, but the paid study does not require advance CPA approval. Your CPA makes the final filing decision.
Do you guarantee tax savings?+
No. A study accelerates the timing of eligible depreciation. Results depend on basis, property facts, placed-in-service dates, passive-loss rules, tax rates and the owner's filing position.
