If your lender asks for a CPA letter for mortgage, don’t panic. It sounds formal (and a little intimidating), but it’s actually a common request—especially if you’re self-employed, run a business, or earn income that doesn’t come from a regular paycheck.
In plain words, the lender wants extra confidence. They want a licensed professional (your CPA) to confirm certain facts about your income, tax filings, or business status. That’s it.
The good news? Once you understand what a CPA letter for mortgage is and how it works, the process becomes much easier. In this article, we’ll break it down in simple English: what it is, why lenders ask for it, what it usually includes, what CPAs can and can’t say, and how to request one without delays.

What Is a CPA Letter for Mortgage?
A CPA letter for mortgage is a written letter from a Certified Public Accountant (CPA) that confirms specific financial facts about a borrower during the mortgage underwriting process.
It is usually requested when the lender needs more clarity about your income or business situation. This happens often with:
- Self-employed individuals
- Freelancers
- Independent contractors
- Small business owners
- Borrowers with multiple income sources
The letter is not meant to “approve” your mortgage. It simply helps verify facts that support your mortgage application.
You can think of it like a professional note that says, “Yes, based on the records I’ve worked with, these details are accurate.”
Why Lenders Ask for a CPA Letter for Mortgage
Mortgage lenders deal with risk every day. Their job is to make sure the borrower’s income is real, stable enough, and documented properly.
For someone with a W-2 job, that process is usually straightforward. The lender can review pay stubs, tax forms, and employment verification. But if you’re self-employed, things can look more complicated on paper.
You may have:
- Income that changes month to month
- Tax deductions that lower taxable income
- Multiple business accounts
- Pass-through income from an LLC or S-corp
- Seasonal revenue patterns
A CPA letter for mortgage helps the lender understand what they’re seeing. It adds professional confirmation and reduces back-and-forth questions during underwriting.
Who Usually Needs a CPA Letter for Mortgage?
Not every borrower gets asked for one. But certain types of borrowers are much more likely to see this request.
Self-Employed Borrowers
If you work for yourself, own a business, or file taxes as a sole proprietor, LLC, or corporation owner, lenders may request a CPA letter for mortgage to confirm your business status and tax history.
Freelancers and Independent Contractors
1099 income is common, but it can look uneven compared to a salary. A CPA letter can help verify your work and reporting history.
Business Owners and Partners
If you own part of a business, lenders may want confirmation of your ownership role, business activity, and financial reporting support.
Borrowers With Complex Income
Even if you have a job, you may also have side income, rental income, consulting income, or a second business. That extra complexity may lead to a request for a CPA letter.
What a CPA Letter for Mortgage Usually Includes
A strong CPA letter for mortgage is typically short, clear, and factual. Underwriters don’t need a long story. They want reliable information they can review quickly.
Here’s what is commonly included:
1. CPA and Firm Details
The letter is usually written on firm letterhead and includes:
- CPA name and credentials
- Firm name
- Contact information
- Date
2. Borrower Information
This identifies the borrower and, where relevant, the borrower’s business name.
3. Relationship Between CPA and Borrower
The CPA may state how they know the borrower, such as:
- Preparing tax returns
- Providing bookkeeping or accounting services
- Working with the borrower for specific tax years
4. Facts Being Confirmed
This is the main section of the letter. It may confirm:
- The borrower is self-employed
- How long the borrower has been in business
- The CPA prepared returns for certain years
- Income shown on tax returns (if requested and supportable)
- The business appears active based on available records
5. Scope Limitations or Disclaimers
Most CPAs include wording that explains what the letter does not do. For example, it may state that:
- No audit was performed
- No assurance is being expressed beyond stated facts
- No guarantee of future income is being made
This is standard and protects everyone involved.
What a CPA Can and Cannot Say
This is one of the most important parts of the process.
Some lenders use templates that ask for statements a CPA may not be able to provide. The wording can sometimes go beyond factual verification and ask for predictions or guarantees.
What a CPA Can Usually Confirm
A CPA can often confirm:
- Historical tax return preparation
- Self-employment status (if supported by records)
- Years in business
- Facts shown in tax documents
- Business activity based on records available
What a CPA Usually Cannot Confirm
A CPA generally cannot state:
- That your income will continue in the future
- That your business will stay profitable
- That you can afford the mortgage
- That you are a low-risk borrower
- Any guarantee about future repayment ability
Why? Because those are future judgments, not accounting facts.
If your CPA revises the lender’s template, that’s normal. It means they are keeping the letter accurate and within professional standards.
How to Request a CPA Letter for Mortgage (Without Delays)
The fastest way to get a useful CPA letter for mortgage is to make a clear request with complete information.
A vague message like “Need a CPA letter ASAP” usually creates delays because your CPA has to follow up and ask what the lender actually needs.
What to Send Your CPA
Include the following in your request:
- Lender’s exact underwriting request or condition
- Lender template/form (if provided)
- Your full legal name
- Business legal name (if applicable)
- Deadline
- Recipient/lender contact or department
- Tax years involved
- Exact details the lender wants confirmed
If the lender wants current-year verification, your CPA may also request updated books or a current profit-and-loss statement.
Request It Early
This is huge. Don’t wait until the mortgage file is urgent. CPA firms may be busy (especially during tax season), and lender templates may need edits before the letter can be signed.
Early requests = smoother closings.
Common Mistakes Borrowers Make
Most delays with a CPA letter for mortgage come from avoidable mistakes. Here are the biggest ones:
1. Waiting Until the Last Minute
You get the lender’s request early but only contact your CPA when the deadline is near. That creates pressure and increases the chance of errors.
2. Sending a Vague Request
If your CPA doesn’t know what the lender wants, they can’t draft the letter properly.
3. Assuming the CPA Will Sign Any Template
Some templates ask for future income guarantees or repayment opinions. CPAs often can’t sign those as written.
4. Not Reviewing the Final Letter
Typos in names, entity names, or tax years can trigger underwriting rejections and revisions.
5. Asking for Unsupported Statements
If the records don’t support it, your CPA shouldn’t include it. Trying to force unsupported wording slows everything down.
How Much Does a CPA Letter for Mortgage Cost?
There’s no universal price for a CPA letter for mortgage. Some CPAs include simple verification letters as part of ongoing service relationships. Others charge separately.
Cost usually depends on:
- Complexity of the request
- Time needed to review records
- Whether the lender’s wording needs revision
- Urgency/rush turnaround
- Level of risk in the requested statements
It’s best to ask about pricing upfront so there are no surprises.
Tips to Make the Mortgage Process Easier (Especially if You’re Self-Employed)
A CPA letter for mortgage helps, but it works best when the rest of your documentation is organized too.
Here are simple ways to strengthen your file:
Keep Bookkeeping Current
Messy books create confusion and slow down verification.
File Taxes on Time
Late or missing tax returns can trigger extra lender questions.
Separate Business and Personal Finances
Cleaner records make it easier for both your CPA and the lender to understand your income.
Maintain Current Financial Statements
A recent P&L can help if the lender wants current-year updates.
Stay Organized
Mortgage underwriting is like a puzzle. If all your pieces are ready, things move faster.
Final Thoughts
A CPA letter for mortgage may feel like one more item on a long underwriting checklist, but it can be a very helpful document—especially for self-employed borrowers, freelancers, and business owners.
It gives lenders a professional, fact-based confirmation that supports your mortgage file and helps clear up questions about your income or business status.
The best approach is simple: request it early, provide complete information, and understand that your CPA can confirm facts—but not predict the future. Do that, and you’ll make the process smoother for everyone involved.
