What Should a CPA Letter Include for a Mortgage Application?

Author : Concepts CPA | Published On : 02 Sep 2026

When a mortgage lender asks for a CPA Letter, one of the first questions borrowers often have is: What should the letter actually include?

There is no single universal CPA Letter that works for every mortgage lender. The information required can vary depending on the lender, loan program, borrower's financial circumstances, and the specific question the lender is trying to address.

For self-employed borrowers and business owners, a CPA Letter for Mortgage may provide additional factual information about their business, self-employment, ownership, or financial circumstances.

Understanding what a CPA Letter may contain can help borrowers communicate more effectively with both their mortgage lender and CPA.

What Is a CPA Letter for a Mortgage?

A CPA Letter is a professional document prepared by a Certified Public Accountant for a specific purpose.

In a mortgage application, the lender may request a CPA Letter when it needs additional information that may be appropriately confirmed by the borrower's CPA.

The letter could address matters such as:

• Self-employment

• Business ownership

• Business structure

• Business activity

• CPA-client relationship

• Other specific information requested by the lender

The contents should be based on the lender's request and information the CPA can appropriately verify.

A CPA Letter is supporting documentation and does not automatically replace tax returns, IRS transcripts, financial statements, bank statements, or other mortgage documents.

Is There a Standard CPA Letter Format?

No universal format applies to every mortgage application.

This is important for borrowers to understand.

A letter accepted by one lender may not necessarily satisfy another lender's requirements.

Some lenders may provide their own form or template. Others may simply provide written instructions explaining what information should be included.

Before asking your CPA to prepare a letter, ask your mortgage lender:

• What information must be included?

• Is there a specific template?

• Is a particular date required?

• Does the lender require additional documentation?

• How should the completed letter be submitted?

Providing these instructions to your CPA can help avoid unnecessary revisions.

Key Information a CPA Letter May Include

Depending on the lender's request, a professional CPA Letter for Mortgage may contain several important sections.

1. CPA or Accounting Firm Information

The letter may identify the CPA or accounting firm preparing the document.

This can include:

• CPA name

• Accounting firm name

• Business address

• Professional contact information

The lender may need this information if it has questions about the document.

2. Date of the Letter

The document should be appropriately dated.

Some lenders may have requirements concerning how recent supporting documentation must be.

If your lender has specified a date range or freshness requirement, provide that information to your CPA before the letter is prepared.

3. Borrower's Name

The letter should clearly identify the borrower to whom the information relates.

The name should be accurate and consistent with the mortgage application and other relevant documents.

4. CPA-Client Relationship

The lender may request information concerning the professional relationship between the CPA and borrower.

For example, the letter may identify that the CPA provides accounting or tax services to the client, when such information is appropriate and can be accurately stated.

The CPA should describe the relationship truthfully.

5. Business Name

If the mortgage request concerns self-employment or business ownership, the lender may want the legal or operating name of the business.

The business name should be consistent with relevant business and tax records.

6. Business Structure

The lender may request information about the structure of the business.

Depending on the borrower, this could involve:

• Sole proprietorship

• LLC

• Partnership

• S corporation

• C corporation

• Other business structures

The CPA should provide accurate information based on the records available.

7. Ownership Information

A lender may request confirmation of the borrower's ownership interest in a business.

For example, the lender may need to know whether the borrower owns all or part of the business.

Ownership information should be supported by appropriate records.

8. Self-Employment Information

A lender may request information concerning the borrower's self-employment.

Depending on the specific request, this may include factual information about the borrower's involvement in the business.

The exact wording should be based on what the CPA can appropriately verify.

9. Nature of the Business

A CPA Letter may describe the general nature of the business when the lender requests this information.

For example, the letter might identify whether the company provides consulting, construction, professional, retail, technology, or other services.

The description should be factual rather than promotional.

10. Other Information Specifically Requested by the Lender

This is perhaps the most important section.

A CPA Letter should address the actual request from the mortgage lender.

If the lender asks the CPA to confirm a particular fact, the CPA can determine whether that information can appropriately be included.

This is why borrowers should provide the lender's written request instead of asking the CPA to create a generic mortgage letter.

What Should Not Be Included in a CPA Letter?

A professional CPA Letter should be accurate, relevant, and appropriately supported.

It should not contain statements that the CPA cannot reasonably verify.

Borrowers should avoid asking a CPA to:

• Guarantee mortgage approval

• Guarantee loan qualification

• State unsupported income figures

• Make promises about future business performance

• Misrepresent business information

• Provide information outside the CPA's professional knowledge

The purpose of the letter is to provide accurate professional information—not to influence the lender through unsupported claims.

CPA Letter for Different Business Structures

The information needed can differ depending on how a business is organized.

Sole Proprietors

A sole proprietor may have business activity reported directly on an individual tax return.

A lender may request documentation concerning the borrower's self-employment or business activity.

LLC Owners

An LLC can have different tax classifications and ownership arrangements.

The lender may request information concerning the borrower's ownership and business structure.

S Corporation Owners

An S corporation owner may receive income through multiple channels, depending on the business and compensation arrangement.

The lender may request additional documentation to understand the borrower's financial situation.

Partnership Owners

Partnership interests can involve multiple owners and different allocations of income.

Additional documentation may be required depending on the mortgage application.

Corporation Owners

Corporation owners may have separate business and personal financial records.

The lender determines what documentation is necessary to evaluate the application.

CPA Letter vs. Profit and Loss Statement

A CPA Letter and a profit and loss statement are different documents.

CPA Letter

Provides specific professional information requested by the lender.

Profit and Loss Statement

Shows business revenue, expenses, and resulting profit or loss for a specified period.

A lender may request both if necessary.

CPA Letter vs. Business Tax Return

A business tax return provides tax information reported to the IRS.

A CPA Letter is prepared separately for a specific purpose.

The two documents can provide different types of information and may both be requested during mortgage underwriting.

Does a CPA Letter Need to Include Income?

Not necessarily.

The information included depends on what the lender is requesting and what the CPA can appropriately verify.

A borrower should not assume that every CPA Letter needs to contain income calculations.

If the lender specifically asks the CPA to address income, provide the lender's request to the CPA so the CPA can determine what can appropriately be stated.

Does a CPA Letter Need to Be on Letterhead?

If your lender has specific formatting requirements, follow them.

If no specific format is provided, professional accounting firms may use their standard business letter format.

The most important consideration is that the document meets the lender's requirements and accurately identifies the professional preparing it.

Does a CPA Letter Need a Signature?

A lender may have specific requirements concerning signatures or verification.

If the lender requires a signed CPA Letter, provide those instructions to your CPA.

The CPA should sign only a document containing information the CPA can appropriately support.

What Supporting Documents May a CPA Need?

Before preparing the letter, your CPA may request information or records such as:

• Tax returns

• Business records

• Accounting records

• Ownership documents

• Business formation documents

• Financial statements

• Other relevant documentation

The records needed depend on what the lender has requested.

How to Make Sure Your CPA Letter Meets Lender Requirements

The easiest way to reduce problems is to follow a simple process.

Get the Lender's Request

Ask the lender exactly what it needs.

Obtain a Template if Available

If the lender provides a form, use that form.

Send the Complete Request to Your CPA

Do not summarize the request from memory.

Provide Supporting Information

Give your CPA the records needed to address the request.

Review the Completed Letter

Check names, dates, business details, and other factual information.

Submit It as Directed

Follow the lender's document-submission instructions.

What If the Lender Says Something Is Missing?

If the lender says your CPA Letter is incomplete, ask exactly what information is missing.

The lender may need:

• A specific statement

• Additional business information

• Updated information

• A different format

• Supporting documentation

• Clarification

Give the lender's response to your CPA.

Do not modify the professional document yourself unless your CPA instructs you to do so.
