A cpa comfort letter gives a lender clear, professional context about a borrower’s numbers.
It explains what a CPA did, what records were checked, and the limits of the work.
It supports loan applications for home loans, mortgages, and refinances.
What a CPA Comfort Letter Is
What is a cpa letter?
A short, signed document from a licensed CPA.
It describes procedures applied to specific records.
It helps underwriters place figures with more credibility and accuracy.
What it covers
- What was reviewed: financial statements, tax forms, and supporting schedules.
- Periods covered and definitions used.
- Procedures performed and any tie-outs to filed IRS returns.
- Limits, assumptions, and a statement that the letter is not an audit.
What it is not
- It is not an assurance report under auditing standards.
- It is not a guarantee about future income, interest costs, or loan performance.
- It is not legal or insurance advice.
Framework: wording follows the AICPA(American Institute of Certified Public Accountants) approach to third-party communication. Many CPAs also reference articles and guidance in the Journal of Accountancy for practical interpretation.
Why Banks and Mortgage Brokers Request It
Underwriters need consistent, traceable information.
A comfort letter can reduce back-and-forth when numbers are complex.
- Credibility. A licensed professional ties figures to books and tax filings.
- Compliance. It supports regulatory compliance and investor documentation.
- Due diligence. It helps internal internal controls by stating scope and limits.
- Context. It explains variances and seasonality in plain language.
Scope: The Boundaries That Protect Everyone
The scope defines what the CPA agrees to do.
Boundaries protect the borrower, the lender, and the firm’s professional liability position.
Typical scope items
- Read or compare financial statements for named periods.
- Agree selected amounts to filed tax forms.
- Compare cash receipts to bank activity at a high level.
- Recalculate simple totals and ratios used by underwriting.
Explicit limits
- No auditing evidence is obtained beyond the stated procedures.
- No opinion on the company’s solvency or future income.
- No assurance on internal accounting controls beyond what is described.
Procedures: What CPAs Commonly Do
Procedures must be specific, reproducible, and easy to follow.
Examples of lender-friendly procedures
- Agreement to filings. Match revenue on the YTD P&L to the most recent IRS-filed return and interim tax schedules, if applicable.
- Bank tie-outs. Compare selected deposit totals to bank statements for defined months.
- Recalculations. Recompute a margin or percentage used in the underwriting worksheet.
- Cross-checks. Tie a balance on the balance sheet to a supporting subledger or third-party statement.
Documentation the borrower should provide
- Prior-year tax forms with all schedules.
- YTD financial statements with comparable prior period.
- Recent bank activity for deposit verification.
- Clarifications for one-time events that affect income.
AICPA Limits: What CPAs Will Not Say
CPAs stay inside professional standards.
That keeps the letter useful and defensible.
- No forward-looking guarantees about home mortgage approvals or interest rates.
- No statement that numbers are “free of misstatement” unless an audit or review is performed under standards.
- No broad assurance on internal controls unless separately engaged.
- No legal opinions on compliance with laws or contracts.
Bottom line: the letter provides verification by procedure, not blanket assurance.
Comfort Letter vs. CPA Income Verification Letter
Both letters help underwriting. They serve different needs.
When to use each
- cpa comfort letter. Focus on procedures and limits. Good for context, reconciliations, and ratio checks.
- cpa income verification letter. Confirms specific income figures for mortgage or home loans based on named records.
Can a file include both?
Yes. Many lenders request a short comfort letter plus a separate income confirmation.
Keep each purpose clear to maintain accuracy and acceptance.
How Lenders Use the Comfort Letter
Underwriters file it with the cash-flow and capacity analysis.
It supports credit decisions without replacing their work.
- Aligns borrower figures to financial statements and tax records.
- Documents the accounting treatment of unusual items.
- Provides traceable notes for investor or audit review of the loan file.
Risks, Liability, and Practical Protections
A clear letter manages risk for all parties.
- Professional liability. CPAs use cautious wording and defined scope.
- Regulatory compliance. The lender shows consistent due diligence steps.
- Borrower clarity. The borrower knows what was and was not tested.
