Cost Seg Atlas vs Cost Segregation Authority: Tax Services Compared

Start with the decision your advisor must help you make

These are two providers to investigate for property-related tax work. The comparison below uses their public descriptions and separate buyer scenarios. It does not establish that both providers offer every service you need.

Published by AE Tax Advisors, a competing provider. This is a source-based service comparison, not an independent ranking, customer review or endorsement.

At a glance: what to put in the two proposals

Cost Seg Atlas: service model and buyer fit

Its public materials describe educational cost segregation analyses and optional technical-review services.

Relevant buyer: Owners exploring a preliminary analysis before purchasing a formal study

Evaluation example: You are evaluating a tool that expressly distinguishes an educational analysis from a signed technical study.

Ask what document you receive, what review upgrades are available, and whether your CPA will accept the deliverable.

Cost Seg Atlas distinguishes downloadable output from an optional licensed review and describes a completeness threshold for that review. Ask which version you are purchasing and what additional work resolves incomplete evidence. A professional signature does not itself establish that an owner can use a projected deduction. Before choosing a product, have the filing professional review the input records and reporting requirements. Compare AE's separately scoped study and advisory services with the complete workflow, including any review upgrade.

Cost Segregation Authority: service model and buyer fit

Its public materials describe cost segregation and related specialty property-tax services.

Relevant buyer: Owners comparing a property-focused specialty tax provider

Evaluation example: You want a study but also need to understand what related services the proposal actually includes.

Ask which property-tax projects, reporting tasks, and support terms are expressly included.

How these two options change your shortlist

Investigate Cost Seg Atlas first when your immediate assignment matches this situation: You are evaluating a tool that expressly distinguishes an educational analysis from a signed technical study.

Investigate Cost Segregation Authority first when this is the closer description: You want a study but also need to understand what related services the proposal actually includes.

If both situations apply, ask whether one lead professional can coordinate the work or whether separate engagements are needed. A stated specialty is a reason to investigate fit, not proof that the other provider lacks that capability.

Two questions that make the comparison concrete

For Cost Seg Atlas: Am I buying an educational analysis or an implementation-ready study?

For Cost Segregation Authority: Does the quote include any work beyond the property study?

Ask both teams to return a written scope identifying the assigned professional, the information needed, the result you will receive and the completion date. Compare answers against your actual entities and income sources, rather than counting the number of services on a website.

Compare fees on the same assignment

This comparison does not assert a current numeric fee for either provider. Request a dated proposal from each. Separate the initial review, recurring accounting, written planning, implementation, business returns, personal returns, state filings and any specialist work. An advertised starting price, consultation fee or subscription is not the complete price for every business.

Put both proposals on the same time horizon. Include first-year onboarding or cleanup, outside-professional costs, required renewals and cancellation terms. Request an explanation of whether a projected benefit is a permanent tax reduction, a timing benefit or simply a deduction. No provider’s fee or service model guarantees savings.

Where AE belongs in the comparison

AE Tax Advisors is another option for business owners, real estate investors and high-income professionals seeking a defined tax advisory engagement. The standard published advisory price is $7,800, payable in two $3,900 installments 30 days apart. Tax returns, amendments, property studies and additional work are separately scoped and priced. The standard engagement does not require an annual planning renewal; confirm the actual duration and deliverables in your agreement.

Ask AE the same two issue-specific questions above. A broader national practice, an investment relationship, a legal assignment, a directory referral or a specialist engineering study may contain work outside AE’s advisory scope. Retain any specialist your facts require.
