A CPA letter for a mortgage is a short document your Certified Public Accountant writes to confirm, for the lender’s underwriter, that you are self-employed, what share of the business you own, how the business is structured, and that it is currently operating. Lenders sometimes call it a comfort letter. It exists because Fannie Mae directs lenders to verify a self-employed borrower’s business through a third party within 120 calendar days of the loan’s note date, and a CPA is one of the preferred sources for that verification.1Fannie Mae. Verbal Verification of Employment
Why Lenders Ask for One
A salaried applicant hands over W-2s and pay stubs, and the lender calls the employer to close the loop. Self-employed borrowers have no employer to call. Income can swing year to year, and tax returns usually show deductions that pull reported income well below what actually moves through the business. The CPA letter gives the underwriter an independent professional’s confirmation of facts that bank statements alone don’t clearly show: that the business exists, that you own the share you say you own, and that a licensed CPA has been looking at the books.
Fannie Mae’s selling guide tells lenders to verify a self-employed borrower’s business through “a third party, such as a CPA, regulatory agency, or the applicable licensing bureau.”1Fannie Mae. Verbal Verification of Employment A CPA letter is often the cleanest of those options, especially when the underwriter also wants some context about the health of the business and not just proof it has a phone number.
There is a specific worry driving the request. If you withdraw a large sum from the business for your down payment or closing costs, and the business can’t absorb it, your income disappears and the loan defaults. The letter helps the underwriter judge whether the business can take that hit and still support your monthly payment.
What the Letter Contains
There is no universal template. Different lenders ask for different things. Most CPA letters cover a common core:
- Confirmation that you are currently self-employed and active in the business.
- Your specific ownership percentage. Fannie Mae treats anyone with 25% or greater ownership as self-employed, which triggers a heavier documentation load.2Fannie Mae. Underwriting Factors and Documentation for a Self-Employed Borrower
- The business structure: sole proprietorship, LLC, S corporation, partnership, or other form.
- How long the CPA has prepared your taxes or handled your books.
- A general statement that the business is in good standing and operational.
- Depending on what the lender asks for, a note about income stability or whether a planned withdrawal appears manageable given current cash flow.
Lenders sometimes push for language suggesting the business will stay profitable, or that a specific withdrawal won’t cause harm. Professional standards sharply limit how far a CPA can go there.
What Your CPA Cannot Say
The American Institute of Certified Public Accountants prohibits CPAs from providing assurance that a business is solvent, will remain solvent, or can repay a specific debt. The AICPA’s attestation interpretations tell practitioners not to give assurance that an entity would not be rendered insolvent by a proposed transaction, or that it has the ability to pay debts as they mature. Those are the exact assurances mortgage lenders most want, and CPAs are not allowed to provide them.
The tension is predictable. The underwriter wants certainty about your financial future; the CPA is limited to historical facts and current conditions. A CPA can confirm that your business generated a certain amount of revenue last year, or that two years of tax returns show consistent income. A CPA cannot say the business will stay profitable, that you will be able to make the mortgage payments, or that pulling $80,000 out for a down payment won’t hurt the business.
The consequences for crossing those lines are real. State boards of accountancy can discipline CPAs for violating professional standards, up to suspension or revocation of a license.3Legal Information Institute. Tennessee Comp R and Regs 0020-04-.03 – Grounds for Discipline Against Licensees A CPA who guarantees your solvency in writing can also face civil liability if you later default. This is why some accountants decline comfort letters outright, and why others draft them in carefully neutral language that verifies facts without wandering into prohibited territory.
If your lender’s requested wording is pushing your CPA into that zone, the fix is usually a conversation between the loan officer and the accountant, not pressure on the CPA to sign something they shouldn’t.
What to Bring Your CPA
Your accountant has to be able to verify what they’re putting in writing, not just take your word. The more organized your file, the faster and cheaper the letter.
- Signed federal income tax returns for the most recent two years, with all schedules. Sole proprietors will need Schedule C; S corporation owners will need Form 1120-S and their personal Schedule K-1.4Fannie Mae. Analyzing Returns for an S Corporation
- A year-to-date profit and loss statement. Lenders want current performance, not just last year’s numbers, especially if more than a quarter has passed since your last filing.
- Business formation documents: articles of incorporation, operating agreement, or partnership agreement showing the legal structure and your ownership percentage.
- A current business license or state registration confirming the entity is active.
- Recent business bank statements, generally 12 to 24 months, showing deposit and cash flow patterns.
If your CPA has been preparing your taxes for years, most of this is already on file. Still, bring current-year documents and anything that has changed since your last return. Surprises during drafting slow everything down and can raise questions with the lender.
What It Costs
Expect anywhere from a few hundred dollars to over $1,000. The range reflects your local market, the complexity of your business, and how much work the CPA has to do beyond confirming things already in their files. If your accountant has prepared your returns for years and just needs to state known facts, the fee lands at the low end. If they have to review unfamiliar records or draft custom language for a demanding underwriter, it climbs. Some CPAs charge a flat fee for these letters; others bill their standard hourly rate.
The best way to hold the cost down is to ask the lender exactly what language they need before your CPA starts writing. Vague requests cause back-and-forth revisions, and each round costs time and money. A sample letter or a specific list of required statements from the loan officer up front lets the CPA work in one pass.
If Your CPA Won’t Write One
Some CPAs decline comfort letters because their liability insurer discourages them, or because the lender’s requested wording crosses ethical lines. Others charge enough that borrowers want another route. Lenders accept several alternatives.
Two years of signed federal tax returns with all schedules remain the backbone of self-employed income verification. If the lender wants independent confirmation that what you handed over matches what you filed, they can request IRS transcripts through Form 4506-C, the IVES request. That form authorizes the IRS to send return transcripts, account transcripts, or wage and income data directly to the lender.5Internal Revenue Service. Form 4506-C IVES Request for Transcript of Tax Return Return transcripts are available for the current year and the prior three processing years.
A year-to-date profit and loss statement covers the current-performance question that a CPA letter often addresses. Providing one proactively signals transparency even when it isn’t strictly required.
For the business-existence step specifically, Fannie Mae lets lenders verify through a regulatory agency, a licensing bureau, or a confirmed phone listing and business address.1Fannie Mae. Verbal Verification of Employment A current business license, a letter from a state licensing board, or a secretary of state business listing can satisfy that requirement without involving your CPA at all.
One boundary worth naming: the CPA letter doesn’t replace tax returns, profit and loss statements, or the lender’s own income analysis. It’s one piece of the file underwriters assemble for a self-employed borrower, not a shortcut around the rest of it.
