Partner program FAQ
Can a CPA firm offer cost segregation without hiring an engineer?
Yes. Through the RentalWriteOff partner programs, your firm offers cost segregation while our team performs the analysis. In the white-label program the report is delivered under your firm’s brand at a price you set; in the referral program you share a tracked link.
What is the difference between the white-label and referral programs?
White-label partners access partner pricing, set their own retail price, deliver under their own brand, and own the client relationship. Referral partners share a tracked link and RentalWriteOff delivers the study.
What property types do you cover?
Single-family rentals, condos, short-term rentals, multifamily, manufactured housing, and commercial properties. Larger or more complex commercial engagements begin with a quick scope review.
What does the report include for my tax team?
Reports include asset-classification schedules, depreciation schedules, methodology documentation, and supporting detail for your firm’s review. Eligible look-back engagements also include Form 3115 preparation; your firm completes the return-specific work and files it.
How long does setup take?
About 20 minutes. Your partner code, branded intake link, and portal access are created in one step, and our support desk is behind your clients from the first study.
Who answers my client’s technical questions?
RentalWriteOff supports questions about the report, supporting documentation, asset classifications, and methodology. Your firm handles tax advice and filing questions.
How fast are studies delivered?
2 business days from complete submission, a turnaround built for extension season and estimated-payment deadlines.
Are the studies defensible in an audit?
Every study is prepared with an engineering-based approach aligned with the IRS Cost Segregation Audit Techniques Guide, passes an expert review before delivery, and includes one round of revisions and audit support: if a study is examined, we provide the documentation and respond to the taxing authority’s inquiries.
What does the white-label program cost?
Partner pricing for standard studies is confirmed during onboarding. Commercial or non-standard work is scoped separately. Qualified new partners may receive a complimentary first standard residential study.
