A bank statement loan is a Non-QM mortgage that lets self-employed borrowers qualify using 12 or 24 months of personal or business bank statements instead of tax returns.

The lender averages eligible deposits, applies an expense factor to business accounts, and treats the result as monthly qualifying income. Approval still depends on credit, assets, down payment, and underwriting guidelines.

Most self-employed borrowers who ask about bank statement loans have the same problem: the business earns well, but the tax return, after write-offs, says otherwise. Here is how the program actually measures your income and what underwriters check along the way.

What is a bank statement loan?

A bank statement loan is a mortgage that verifies a self-employed borrower’s income through deposits in their bank accounts rather than through tax returns, W-2s, or pay stubs. It is a form of alternative income documentation, and it falls into the Non-QM category.

Non-QM (non-qualified mortgage) means the loan sits outside the federal Qualified Mortgage standards, which rely heavily on tax-return income for self-employed borrowers. Non-QM does not mean unregulated: lenders must still make a reasonable, good-faith determination that you can repay the loan under the CFPB’s Ability-to-Repay rule.

For self-employed income verification, this changes one key input. A conventional loan qualifies you on net income after deductions, which is the number on your Schedule C or K-1. A bank statement loan qualifies you on cash flow into your accounts. For a borrower who writes off heavily, those two numbers can be far apart.

“Most of our self-employed clients aren’t hiding income. They’re running a business the way their CPA told them to, and the tax return reflects that. A bank statement loan lets us look at what the business actually brings in.”

— Charlie Cooper, President, Austin Capital Mortgage

What happens during bank statement underwriting?

Bank statement underwriting is the lender’s review of 12 or 24 consecutive months of statements to calculate a stable monthly income from your deposits. The underwriter adds up eligible deposits, removes anything that is not business income, applies an expense factor if the account is a business account, and divides by the number of months reviewed.

Whether you submit 12 or 24 months depends on the program and your file. A 24-month window smooths out seasonal swings; a 12-month window can help when the business has grown recently. For the full document list, see the requirements for a bank statement loan.

How is income calculated from business bank statements?

Business account income is calculated by multiplying total eligible deposits by an expense factor, then averaging over the statement period. The expense factor is a percentage the lender assumes goes to business costs. A common default is 50%, and some programs allow a lower figure when a CPA letter or profit and loss statement supports it.

Here is a simplified example using a 50% expense factor:

StepCalculationResult
Eligible deposits over 12 months$15,000 x 12$180,000
Apply 50% expense factor$180,000 x 50%$90,000
Monthly qualifying income$90,000 / 12$7,500 per month

Expense factors, statement periods, and calculation methods vary by lender, program, and investor guidelines.

How are personal bank statements treated?

Personal bank statements are usually counted at up to 100% of eligible deposits, because business expenses are assumed to have been paid before money moved to your personal account. The tradeoff is documentation: lenders generally want to see that the deposits trace back to your business, and some require business statements as well to confirm the source.

What deposits do underwriters remove?

Underwriters separate ongoing business income from money that is not. Here is how deposits are usually treated:

Usually counts as incomeUsually removed by underwriters
Client payments by check, ACH, or wireTransfers between your own accounts
Payment processor and marketplace payoutsLoan proceeds, credit line draws, and cash advances
Merchant card depositsTax refunds and insurance payouts
Invoice payments you can documentLarge one-time deposits with no documentation

Any deposit an underwriter cannot trace may be excluded or require a written explanation with backup.

Who are bank statement loans designed for?

Bank statement loans are designed for self-employed borrowers whose tax returns show less income than their business actually generates, most often because of legitimate deductions. Common fits include:

  • Business owners with an S-corp or LLC who pay themselves irregularly
  • Freelancers and consultants with clients across several platforms
  • 1099 contractors with strong deposits but high business expenses
  • Borrowers with seasonal or uneven income who need a longer averaging window

What are the self-employed borrower requirements?

Self-employed borrower requirements for bank statement programs usually center on proof that the business exists and has been operating long enough to show stable deposits. Lenders commonly ask for:

  • Two years of self-employment history, with some programs accepting less when you have prior experience in the same field
  • A CPA letter, business license, or other third-party verification of the business
  • Documentation of your ownership percentage in the business
  • Consecutive statements for every account used to calculate income

If most of your income arrives on 1099 forms and you have not written off much, a 1099 loan may be a simpler route for 1099 mortgage qualification. See the 1099 loan requirements.

What else do lenders review besides your deposits?

Lenders review your full credit and financial profile, not just your deposits. The income from your statements is only one input into the approval decision. Underwriters also look at:

  • Credit score and history: Minimum scores vary by program, and a higher score can open more options.
  • Debt-to-income ratio (DTI): DTI is your total monthly debt payments divided by your monthly qualifying income. Your bank statement income is the denominator.
  • Down payment and loan-to-value: Bank statement programs generally expect more equity than conventional financing.
  • Cash reserves: Reserves are liquid funds left after closing, measured in months of mortgage payments. Many Non-QM programs require them.
  • Property type and occupancy: Primary residences, second homes, and investment properties can have different guidelines.

“The deposits get you in the conversation. Credit, reserves, and how much you’re putting down are what shape the actual loan terms.”

How do bank statement loans compare to other alternative income documentation?

A bank statement loan is one of several ways a self-employed borrower can document income. The right one depends on what your paperwork shows and how much you write off. This overview is a starting point, not a full comparison.

ProgramIncome documented withIncome basisBest fit
Bank Statement Loan12 or 24 months of bank statementsEligible deposits, less expense factor on business accountsHeavy write-offs, strong cash flow
1099 Loan1099 forms, often 1 to 2 yearsGross 1099 income, less an expense factorContractors paid mainly on 1099s
P&L-Only LoanCPA-prepared profit and loss statementNet profit shown on the P&LOwners with a CPA and clean books
ConventionalTax returns, usually 2 yearsNet income after deductionsTax returns show enough income
FHATax returns, usually 2 yearsNet income after deductionsLower down payment, tax returns support income

Availability and guidelines for each program vary by lender, program, and state.

What do borrowers often get wrong about bank statement loans?

Borrowers most often assume a bank statement loan requires little documentation or ignores their business expenses. Both assumptions can lead to surprises during underwriting.

MythFact
“A bank statement loan is a no-doc loan.”No. It replaces tax returns with a different set of documents. Underwriters review every page of every statement, question unusual deposits, verify the business, and still check your credit, assets, and identity.
“My write-offs won’t matter anymore.”Not entirely. Write-offs no longer reduce income the way they do on a tax return, but the expense factor still accounts for business costs. A CPA letter or P&L may support a lower factor if your real expenses are below the default.
“The rate will match a conventional loan.”Non-QM pricing is generally higher than comparable conventional loans because the lender takes on more risk. Your credit, down payment, reserves, and program all affect how much higher, so compare quotes side by side.

“I’d rather a borrower walk in knowing the tradeoffs. When they understand how the income is calculated, we can plan the file around their strengths.”

— Charlie Cooper, President, Austin Capital Mortgage

A Real Borrower Scenario

An Austin-area design studio owner deposited about $15,000 a month into her business account. After legitimate write-offs for equipment, software, and contractors, her tax returns showed roughly $40,000 in annual income, or about $3,333 a month.

On a conventional loan, that $3,333 figure produced a debt-to-income ratio too high for the home she wanted. Her loan officer reviewed 24 months of business statements.

After removing transfers from her personal savings, eligible deposits averaged $15,000 a month. With a 50% expense factor, her qualifying income came to $7,500 a month, more than double her tax-return income. Her credit, down payment, and reserves met program guidelines, and she moved forward with a purchase that fit her budget.

“A self-employed borrower whose tax returns show low income after write-offs can qualify on bank deposits instead, because a bank statement loan measures cash flow rather than taxable income.”

— Charlie Cooper, President, Austin Capital Mortgage

Scenario is illustrative; approval is subject to underwriting review and program eligibility.

Frequently asked questions

Yes, a bank statement loan may help. Instead of the $40,000 on your tax return, the lender would calculate income from your deposits. With $15,000 in eligible monthly deposits and a 50% expense factor, qualifying income would be about $7,500 a month. Credit, down payment, reserves, and underwriting review still determine approval.

Lenders total your eligible deposits over 12 or 24 months, subtract non-income items such as transfers and loan proceeds, apply an expense factor to business accounts, and divide by the number of months. The result is your monthly qualifying income, which the lender uses to calculate your debt-to-income ratio.

You can use either, depending on the program and how your money flows. Business statements are counted after an expense factor. Personal statements are usually counted at up to 100% of eligible deposits, but lenders want to see the deposits come from your business. Some borrowers submit both.

It depends on your expenses and how you are paid. A 1099 loan uses your 1099 forms and can be simpler when most income arrives that way. A bank statement loan may produce higher qualifying income if you have deposits from several sources. With 12 months of history, prior experience in the same field matters for both programs.

Transfers between your own accounts are removed from the income calculation, so they do not count toward income. A large one-time deposit is usually excluded or needs documentation showing it is business income. Neither automatically disqualifies you, but unexplained deposits can slow underwriting and lower your calculated income.

Yes, many bank statement programs allow rate-and-term refinances and cash-out refinances on eligible properties. Income is calculated the same way as on a purchase. Loan-to-value limits for cash-out refinances are usually tighter than for purchases, and guidelines vary by program.

Some bank statement programs allow investment properties, subject to different down payment, reserve, and credit guidelines than a primary residence. If the property’s rental income will cover the payment, a DSCR loan may also be worth reviewing with your loan officer.

A bank statement loan can take longer than a conventional loan because underwriters review every statement in detail. Austin Capital Mortgage can close in as little as 10 to 21 days when documents are complete. Missing statements or unexplained deposits are the most common causes of delay.

Possibly. Minimum credit scores for bank statement programs vary by lender and investor, and some programs accept scores below 700. A lower score can mean a larger down payment, more reserves, or different pricing. A loan officer can check which programs match your credit profile.
