CPA-led cost segregation analysis and return coordination

Tavella CPA Group provides CPA-led cost-segregation tax analysis and return coordination for owners of rental and business property. Depending on the property and available records, an engagement may involve a document-based tax analysis prepared from reliable acquisition, construction, renovation, cost, and placed-in-service records, or review and coordination of a study prepared by a qualified independent provider. Tavella CPA Group does not claim engineering credentials or issue an engineering certification. When a site inspection, quantity takeoff, engineering judgment, construction-cost estimate, appraisal, valuation, or other engineering-based work is required, that component must be performed by an appropriately qualified independent provider. Each asset classification, cost allocation, depreciation method, tax year, and state treatment depends on the facts, current law, available support, and written engagement. No property automatically qualifies, and no deduction, refund, or tax savings is guaranteed.

BEFORE YOU REQUEST A CALL

See what fits this service and what is scoped separately

This service may be a fit when

  • You acquired, constructed, or materially renovated rental or business real estate and have reliable property and cost records available for review
  • You want to determine whether a CPA-led document-based cost-segregation analysis is supportable
  • A qualified independent provider has prepared a study that must be reviewed before return implementation
  • The assignment may require coordination with an independent provider for engineering, inspection, quantity analysis, or cost-estimating work
  • A prior-year property classification may require accounting-method or Form 3115 review
  • You want supported classifications coordinated with depreciation schedules, state treatment, estimates, and future disposition records

These items require separate scope or another professional

  • Engineering certification, property inspection, quantity takeoffs, construction-cost estimates, appraisal, and valuation
  • Legal advice, purchase or financing diligence, and investment recommendations
  • Bookkeeping reconstruction, missing-basis reconstruction, or unsupported cost reconstruction
  • Every owner, entity, property, return, state, amendment, Form 3115, examination, notice, and future disposition not included in the signed engagement

Determine which analysis and professional roles the property requires

For the initial scope review, identify the property type and state, ownership, acquisition or construction year, placed-in-service year, current tax-return status, available cost and construction records, whether an independent study exists, and the next filing or planning deadline. Tavella CPA Group will determine whether the requested tax work can be supported through a CPA-led document-based analysis or whether an independent provider is needed for inspection, engineering, quantity analysis, or cost-estimating work. Do not send a study, appraisal, closing statement, tax return, depreciation schedule, property address, account number, or other sensitive record through the public form. If the engagement is accepted, records are exchanged through the secure portal and each party’s responsibility is identified in writing.

ANTICIPATED DELIVERABLE

The deliverable is CPA tax analysis and return work—not an engineering certification

The signed engagement controls the deliverable. Tavella CPA Group does not issue an engineering certification, appraisal, valuation, or promised deduction. Depending on the accepted scope, the available records, and whether an independent provider is involved, the CPA tax deliverable may include the following:

  • A written scope identifying the property, owner or entity, tax years, jurisdictions, analysis, return work, and each professional’s responsibility
  • A document-based tax-classification and cost-allocation schedule when the available records provide sufficient support
  • CPA review questions, cost-reconciliation comments, or tax-classification comments for an independent provider when coordination is included
  • Updated depreciation schedules and affected federal or state tax-return forms
  • A tax projection, accounting-method review, Section 481(a) calculation, or Form 3115 analysis only when expressly included in the engagement

COMMON QUESTIONS

Questions about cost segregation tax analysis and return coordination

Can Tavella CPA Group prepare the cost-segregation analysis?

Depending on the property and available records, Tavella CPA Group may prepare a CPA-led, document-based cost-segregation tax analysis and the related depreciation and return work. Tavella CPA Group does not provide an engineering certification, property inspection, quantity takeoff, construction-cost estimate, appraisal, or valuation. When those elements are necessary for reliable support, the engagement must include or coordinate with an appropriately qualified independent provider. The signed engagement identifies the analysis, deliverables, assumptions, records, and professional responsibilities included.

What may Tavella CPA Group deliver for an accepted cost-segregation engagement?

The deliverable is the CPA tax work listed in the signed engagement, not an engineering certification. It may include a document-based tax-classification and cost-allocation schedule, review questions for an independent provider, cost-reconciliation or tax-classification comments, updated depreciation schedules, affected return forms, or a separately accepted projection, Section 481(a) calculation, or Form 3115 analysis. Nothing is included unless the written scope says it is.

What records are commonly needed for the tax review?

Common records include the purchase agreement and closing statement, construction or renovation cost detail, invoices, land allocation support, placed-in-service dates, prior returns and depreciation schedules, ownership records, an independent study and appendices when one exists, and information about use, improvements, dispositions, states, and filing deadlines. Sensitive documents are requested through the secure portal only after engagement setup.

Can cost segregation be considered after a property was placed in service?

Potentially. A later analysis or study can raise depreciation-correction, accounting-method, Section 481(a), and Form 3115 questions. The correct path depends on prior depreciation, tax years, property classifications, procedural rules, available support, and current guidance. An amended return or Form 3115 is not automatic and is separately scoped when review supports it.

Does cost segregation guarantee bonus depreciation or tax savings?

No. Classification does not make land or an entire building eligible for bonus depreciation, Section 179, or other accelerated depreciation, and eligibility depends on the asset, acquisition and placed-in-service dates, tax year, use, ownership, elections, and current law. Basis, passive-activity limits, loss limitations, state conformity, future sales, and recapture can change the practical result. No deduction, refund, or tax savings is guaranteed.

Why do future sales and state returns matter?

Accelerated depreciation can shift deductions between years and changes the asset detail carried into a later sale or disposition. Federal Sections 1245 and 1250, depreciation recapture, suspended losses, basis, and state conformity may affect later reporting. Each relevant state and tax year must be reviewed separately.

Is the IRS Cost Segregation Audit Technique Guide binding tax law?

No. The IRS's February 2025 Publication 5653 explains examination approaches and characteristics of studies, but it states that it is not an official pronouncement of law or the IRS's position and cannot be relied upon as such. Current statutes, regulations, cases, procedures, forms, instructions, and other applicable guidance control the tax analysis.
