Late cost segregation studies can still create meaningful value for residential rental clients, especially when short-life components and land improvements were not identified at acquisition.
RentalWriteOff delivers engineering-style rigor in a cost segregation documentation package, typically in 2 business days, with a streamlined intake requiring about 5 minutes of client time. CPAs can submit through our Partner Portal, partnership programs are available, and audit support is included with every report we deliver.
When CPAs consider a late study
- Client depreciated everything as 27.5-year building
- Property had renovations or major improvements
- Client has taxable income and would benefit from accelerated depreciation
Form 3115 workflow support
If the study is performed after depreciation has already been claimed, a CPA may consider Form 3115 (Accounting Method Change) to claim a catch-up adjustment where appropriate. RentalWriteOff offers Form 3115 support as an add-on.
CPA workflow checklist
- Confirm placed-in-service date (facts and circumstances)
- Confirm basis and reconcile to tax records
- Collect supporting documentation (appraisal recommended)
- Review asset schedule and bonus depreciation applicability
- Retain the documentation package in the permanent file
Risk management and audit-readiness
Late studies are common. The key is consistent, supported basis allocation and classification logic. Audit support included with every report provides additional confidence if questions arise later.
