What is a CPA letter

A CPA letter is a signed statement on CPA letterhead where a CPA confirms facts from records, such as self-employment, ownership share and figures from filed returns. Underwriters request one when a borrower earns income from a business they own.

Loan officers use other names for it. One may ask for a CPA comfort letter for mortgage review, another for an accountant's letter for mortgage lender files. Whatever the label, a CPA signs to the same limits.

Who needs a CPA letter for a mortgage

We write a CPA letter for self-employed mortgage files for:

  • Sole proprietors and single member LLC owners who report business income on Schedule C.
  • 1099 contractors paid by clients who issue no W-2.
  • Partners and LLC members who receive their share of income on a Schedule K-1.
  • S corporation owners who pay themselves wages and also report business income on a K-1.
  • Owners who started or changed a business after their last filed return.

When we prepare the returns and keep the books, we match both to the letter before an underwriter compares them.

Types of CPA letters mortgage lenders request

Underwriters pick the letter based on how they count the borrower's income, and some ask for two.

  • Self-employment verification letter.

    We confirm the business name, the owner's share and the tax years the owner reported the activity.

  • Net profit letter.

    We state net profit or K-1 income for each year exactly as filed. Lenders can pull IRS transcripts through Form 4506-C, so we quote the returns to the dollar.

  • CPA letter for use of business funds.

    When an owner takes part of the down payment from business cash, we confirm account ownership and the book balance on a stated date.

  • CPA expense ratio letter.

    Bank statement loan lenders count deposits as income, less an expense ratio for business costs. We state the ratio we trace to the books and returns.

  • Profit and loss statement for mortgage.

    Fannie Mae lets a lender use a profit and loss statement, audited or unaudited, for a self-employed borrower. We prepare it from reconciled books.

CPA letter when the latest return is on extension

If your latest return is on extension, we cannot quote that year in the letter. Individual returns on extension are due October 15, and calendar year partnership and S corporation returns on extension are due September 15.

We can prepare and file the return first, then write the letter from it. If the closing date is fixed, send us the extension confirmation and current books. The lender decides whether those records are enough.

What a CPA can sign for a lender

When a lender asks a CPA to vouch for the loan decision or future income, we rewrite the line. The Nebraska Board of Public Accountancy has reminded CPAs that the lender underwrites the loan, and that CPAs should give no assurance of solvency.

Lender's lineWhat we sign instead
The borrower can afford this loanNet profit as reported on filed returns
Income will continue at this levelYears of filed returns showing the activity
The withdrawal will not harm the businessAccount ownership and book balance on a date
We verified these figuresFigures agree with returns as filed
The business is in good standingEntity type and ownership share per the returns

If a lender wants financial statements instead, we can prepare a compiled financial statement.

Forward the draft with the closing date. A CPA marks each line we can sign as written.

Freddie Mac found forged CPA letters in ten loans in one fraud review, some claiming the business could spare the cash. Freddie Mac advises lenders who doubt a CPA letter to contact the person named on the letterhead.

  • 120 days

    Fannie Mae has lenders verify a self-employed borrower's business no more than 120 calendar days before the note date, the day the loan closes. If the parties push closing past that window, the lender verifies the business again and can ask us for an updated letter.

How to get a CPA letter for mortgage

  1. Forward the lender's request.

    Send the exact wording, the recipient's name, the loan number and the closing date. A screenshot of the loan officer's email is enough.

  2. Sign the disclosure consent.

    We need your written consent before sharing tax return information with a lender, under 26 CFR 301.7216-3.

  3. Read the draft.

    A CPA traces each line to the returns or books and sends you the draft.

  4. Receive the signed letter.

    We send the signed letter within a few business days of receiving the records, by email to you or straight to the loan officer.

What affects the cost of a CPA letter

A CPA quotes a flat fee before any work starts. What we price against:

  • Who prepared the returns. If we filed them, we draft from our own files. For new clients, we review filed returns and IRS transcripts first.
  • Which letter the lender wants. We spend less time on a self-employment confirmation than on an expense ratio letter or a year-to-date profit and loss statement.
  • How current the books are. If the books are months behind, we reconcile them before stating any current figure.

These are the factors, not a quote.
