Secure document sharing with a provider

The decision this guide addresses

Cost segregation files can contain ownership and financial information that deserves controlled access.

Use the agreed secure upload process and limit the records to what the engagement requires. Confirm permissions before sharing third-party files.

Make this review concrete

Confirm the upload destination, authorized recipients, and whether shared links expire. Send only the records needed for the scope and label sensitive documents clearly. If a manager holds third-party data, obtain the owner's authorization and use the agreed channel. Do not attach login credentials or expose guest information in technical photographs.

A practical review sequence

Remove unnecessary personal identifiers from reference images or inventories while retaining essential ownership evidence.

Begin with the actual property and engagement being considered. Keep a written distinction between confirmed facts, estimates, services being purchased, and decisions reserved for the return preparer. If a seller or provider presents only a headline benefit, ask for the underlying evidence and assumptions before making a comparison.

Working review sheet

A hypothetical problem to recognize

A manager proposes sending complete tax returns through a public file link.

Treat the missing explanation as an open item. Ask for a written response, connect it to the affected records, and determine whether it changes the proposed scope or feasibility. This scenario is an editorial illustration, not a testimonial or evidence that a particular provider has performed deficient work.

Questions for the next conversation

What evidence supports the proposed conclusion for this property? Which facts or records could change the answer? Who is responsible for resolving them, and is that work included in the quoted engagement? These questions are more useful when they identify a specific document, asset row, or service than when they request a general assurance of quality.

Ask what the final deliverable will contain and how the preparer will receive it. Where the question affects costs or implementation, request a revised written scope rather than relying on a sales-call recollection. Where it affects tax treatment, the preparer should apply the current rules to the taxpayer rather than extrapolate from another property.

Complete the decision record

Retain the relevant proposal, response, source documents, final report version, and implementation notes in the property file. Record what remains unresolved and whether it must be addressed before engagement, before report delivery, or before filing. A documented decision is easier to review later than an unexplained schedule or an isolated benefit estimate.

Stratum focuses on component evidence and reporting. Broader tax planning, method changes, state calculations, and return preparation need defined responsibilities and an agreed scope. Confirm those roles so the property work produces a useful handoff rather than an assumption that one purchased service includes every related task.
