How a CPA Letter Raises Bank Statement Income for an LLC Owner

The Quick Read: A CPA letter raises qualifying income only when the accountant certifies that your business overhead is lower than the lender’s default assumption, because the letter changes the expense factor and never the deposits. Lenders convert your deposits into income by removing a share for business expenses, and the letter replaces the default share with a documented one.

• The letter is optional on most programs, and it can lower your income as easily as raise it.
• It applies mainly to business account statements, not personal ones.
• The preparer’s letterhead, name, and statement date range must match the file exactly.
• The underwriter tests the letter against real account activity, and the lender sets the final factor.
• Owner-occupied files use a consumer mortgage; a non-owner-occupied rental is a business-purpose loan.

If you own an LLC and bank-statement documentation is your route, this is the one document that can move your number without a single new deposit. Here is how it works, where it fails, and how to decide whether to ask your accountant for it.

What Is Bank Statement Income for an LLC Owner?

Bank statement income is a way to qualify using your deposits instead of traditional personal-income documentation. The lender reviews 12 months of statements, business or personal, and averages the deposits. It then removes an expense share to estimate what you actually take home.

That matters for LLC owners because traditional personal-income documentation often understates cash flow. Write-offs, depreciation, and payroll can shrink taxable income while the account stays busy. Across our wholesale network, qualifying income comes from deposit averages with lender-specific expense factors. There is no universal formula, and you should never assume one.

This is alternative documentation. It is not “no documentation.” The deposits are independently verified, and the loan is reviewed on documented income under the applicable program, subject to lender guidelines.

Key Terms Defined

Expense factor: the share of business deposits a lender treats as overhead, so it does not count as your income.

CPA letter (expense factor letter): a signed statement from a CPA or tax preparer certifying what share of revenue goes to business expenses.

Eligible deposits: the deposits that reflect real business revenue, after transfers, loan proceeds, owner contributions, and one-time items come out.

Ownership share: your percentage of a multi-member LLC, which decides how much of the business income is yours.

Qualifying income: the monthly figure the lender uses to size your loan after the factor is applied.

How Is the Number Built, Step by Step?

The number comes from six steps: pick the statements, strip ineligible deposits, average, apply the factor, apply ownership share, and test it against the file. The factor step is the only one the CPA letter touches. Every other step works the same with or without it.

1. Choose the statement source. Business statements from the LLC’s account get an expense factor. Personal statements usually do not.

2. Gather the statements. Programs commonly use 12 months, and some use 24. A transaction-history printout does not stand in for statements.

3. Remove non-revenue deposits. Transfers between your own accounts, loan proceeds, owner contributions, and one-time items come out.

4. Average over the months used. The result is the monthly eligible deposit figure.

5. Apply the expense factor. A default fixed factor applies unless a CPA letter documents a different figure.

6. Apply ownership share if you own part of the LLC.

Here is a labeled hypothetical, not a program term. Say the eligible deposits average out to a round 100 units a month. At a 50% factor, qualifying income is 50 units. If your CPA certifies a 30% factor, it becomes 70 units. That is a 40% increase in income with identical deposits. Real factors vary by lender, business type, and file.

Notice the order. The table starts from monthly deposits that are already averaged, then applies the factor, then applies your ownership share. Each step builds on the one before it. Skipping ownership share is a common mistake in multi-member LLCs.

What Does the CPA Actually Do?

The CPA reviews your books and certifies what share of revenue goes to operating expenses. That usually means looking at the profit-and-loss statement, the general ledger, and the tax return. The accountant classifies what is a true business cost and what is owner pay.

Payroll, cost of goods, rent, software, and contractors count as expenses. Owner draws and distributions generally do not. Depreciation is a judgment call, since it is a tax expense but not cash leaving the account. How it is treated is part of why a CPA’s ratio can differ from a tax return’s picture.

A CPA will usually attest only to what the records support. Some decline because of professional-liability concerns or because they have never written one. If that happens, ask what scope they are comfortable certifying, or ask the lender whether the default factor is workable for your file.

What Must the Letter Say?

The letter must be on the preparer’s letterhead, name the preparer, state the certified expense ratio, and cover the exact date range of the statements. Mismatched dates are a common reason a letter gets sent back. It should also name you, the entity, and your role.

Ask your accountant for a letter with three parts:

• Who prepared it. The letter gives the preparer’s name, credentials, and firm. It states that the preparer has handled the books or returns for your LLC, names you as an owner, and gives your ownership percentage.
• What it certifies. The letter names the first and last month of the statement period. It then certifies operating expenses as a percentage of gross revenue for that exact period.
• Who signed it. The preparer signs and dates the letter.

Give your CPA that factual ask, not a target number. A letter that reads like it was engineered backward invites scrutiny. The ratio should come from the records.

Is a CPA Letter Required?

No. Most programs apply a standard factor by default, and the letter is an optional override. Requirements differ across lenders, which is why you should confirm with your loan officer before paying for one. Some lenders also want a letter to confirm ownership or tenure, which is a different use.

The letter also is not a document substitute. It generally cannot replace the bank statements themselves, and it does not prove income by itself.

Do You Need One? A Quick Decision Table

The letter can cut either way. If your real overhead is above the default, the certified figure lowers your income, and you gain nothing by offering it. Ask your CPA for a rough ratio before committing to the formal letter.

How Do LLC Types Change the Analysis?

The entity’s tax classification changes which documents matter, though the deposit-and-factor mechanics stay the same.

Account structure matters as much as the letter. Deposits that land in your personal account are often not reduced by a factor. Transfers from your business account into your personal account may count at 100% under some programs, and that rule is separate from the letter. Because lenders differ here, some files qualify better on personal statements and others on business ones. Seeing many lenders’ guidelines is how a broker steers you to the right fit.

Where the Letter Breaks Down

The underwriter checks the letter against your actual account activity, and the lender, not you or the CPA, sets the final factor. Several things cause trouble:

• Mismatch with the file. The ratio must reconcile with the deposits, the tax return, and any P&L. Surprises prompt questions.
• Commingling. Mixing personal and business money muddies deposit sourcing and can shrink eligible deposits.
• Large unexplained deposits and overdrafts. Both draw scrutiny whatever the letter says.
• Wrong dates or names. A letter outside the statement window does not apply.

Keep the accounts clean for the full statement period. The tidiest file usually wins more income than the cleverest letter.

Lenders also verify what they rely on. If a loan is owner-occupied, it is a consumer mortgage, and the federal ability-to-repay rule requires a good-faith determination based on verified information. The CFPB’s compliance guide lists self-employment among the income types a creditor may consider and verify. A bank-statement loan on a non-owner-occupied rental, including a short-term rental, is business-purpose and exempt from those consumer disclosure rules. Either way, deposits are verified, so this is nothing like the stated-income loans of the past.

What Leverage Should You Expect?

Leverage depends on occupancy. On a primary residence purchase or rate-term refinance, select lenders in our network go up to 90% LTV, with the strongest files earning the top of the range. On an owner-occupied cash-out, the ceiling is up to 80% LTV with a fixed expense ratio, or 75% with an accountant-prepared ratio. On an investment-property cash-out, leverage tops out around 75% LTV. Investment purchase leverage on bank statements varies by lender.

Loan sizes typically run from $125,000 to $3,500,000, and reserves commonly sit around six months of the housing payment. These are typical ranges, not promises, and each file is underwritten individually.

Notice what the accountant-prepared ratio does on owner-occupied cash-out: it lowers the maximum LTV from 80% to 75%. Higher income can come with tighter leverage, so weigh both.

How the Letter Differs From a DSCR File

A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Your business income is not the basis, so a CPA letter is generally irrelevant there. If your rentals cover themselves, that route may fit better. Lendmire’s complete DSCR loans guide covers it, and the bank-statement path suits owners whose strength is business cash flow.

What To Do Next

1. Ask your loan officer whether your program uses a default factor and what it is.

2. Ask your CPA for a rough overhead ratio before ordering the letter.

3. Confirm the statement date range, and make the letter match it exactly.

4. Keep business and personal money separate from here on.

5. Run the math on the default and the certified factor, after ownership share.
