How do bank statement loans work for self-employed borrowers?

A bank statement loan lets a self-employed borrower qualify on 12 or 24 months of bank deposits instead of tax returns. The lender adds up eligible deposits, subtracts an expense factor for business statements, and divides by the number of months to get qualifying monthly income. That calculation rests on non-QM lender program guidelines and on the federal ability-to-repay rule, which accepts financial institution records as income verification.

A bank statement loan is a mortgage that documents a self-employed borrower's income with personal or business bank statements rather than tax returns or W-2s. It is usually a non-QM product, built for owners whose tax returns show lower net income after business write-offs than the business actually deposits.

How do lenders calculate income from bank statements?

The lender totals eligible deposits over 12 or 24 months, removes anything that is not business income, and applies an expense factor to business statements. Personal statements are often counted at 100% of eligible deposits. The result is divided by 12 or 24 to give monthly qualifying income, then multiplied by your ownership share.

The common default is a fixed 50% expense factor. Angel Oak's bank statement program qualifies loans at a 50% default and uses 70% for some higher-expense industries. A lower factor requires a statement from a third-party CPA, tax preparer or bookkeeping company. A&D Mortgage counts 100% of deposits on personal statements and a 50% standard expense ratio on business statements, which a third-party expense letter or P&L can lower. One published non-QM program guide sets the minimum expense factor at 10%, even with a CPA statement.

The tables below are a hypothetical illustration. They are not an offer, and real underwriting may treat the same deposits differently.

Table 1. Hypothetical business account, 12 months, 100% ownership.

Month	Total deposits	Excluded	Reason excluded	Eligible deposits
1	$28,400	$0		$28,400
2	$24,900	$5,000	Transfer from personal savings	$19,900
3	$31,200	$0		$31,200
4	$26,700	$0		$26,700
5	$33,800	$2,300	IRS refund	$31,500
6	$29,100	$0		$29,100
7	$27,500	$0		$27,500
8	$46,600	$16,000	Sale of a personal vehicle (large deposit, sourced by letter)	$30,600
9	$30,300	$0		$30,300
10	$25,800	$0		$25,800
11	$32,400	$0		$32,400
12	$29,600	$1,200	Credit card refund	$28,400
Total	$366,300	$24,500		$341,800

Table 2. Hypothetical qualifying income by method.

Method	Eligible deposits	Expense factor	Net after expenses	Months	Qualifying monthly income
Business statements, fixed expense factor	$341,800	50%	$170,900	12	$14,242
Business statements, CPA-prepared expense ratio	$341,800	30%	$239,260	12	$19,938
Personal statements, 100% of eligible deposits	$198,000	0%	$198,000	12	$16,500

In the personal-statement row, the owner moved $16,500 a month from the business account to a personal account. The personal account also received $9,600 of rental income and $7,200 of transfers from savings, for $214,800 in total deposits. Both of those items are excluded, leaving $198,000.

Ownership changes the math. The same business deposits at a 50% factor and 50% ownership would give $7,121 a month instead of $14,242.

Should you use 12 or 24 months of business or personal statements?

Twelve months suits a business with steady or rising deposits. Twenty-four months smooths out a strong year followed by a weaker one, or a seasonal business. Personal statements avoid the expense factor but only count money you actually paid yourself, so the better choice depends on how cash moves between your accounts.

Many lenders accept either period. Angel Oak and A&D Mortgage both list 12 or 24 months of business or personal statements on their program pages.

Lenders also watch the trend. One non-QM program guide allows up to a 10% decline when comparing the last six months with the prior six on a 12-month file. A bigger drop triggers a request for 12 more months. On a 24-month file, a year-over-year decline above 10% is ineligible under that guide.

A 24-month average can cost you if the business has grown. In the example above, if the prior 12 months had $300,000 of eligible deposits, the 24-month figure at a 50% factor would be $641,800 x 50% / 24 = $13,371 a month, versus $14,242 on 12 months.

Personal statements carry their own rule. The same guide requires 2 months of business statements to show the personal and business accounts are separate. Without them, personal statements are treated as business statements with an expense factor.

Ask for the calculation both ways before you choose a program.

Which deposits are excluded from qualifying income?

Lenders count only deposits that look like business revenue. Transfers between your own accounts, tax refunds, loan proceeds, refunds and one-off sales of personal items are removed. Large deposits need a written explanation, and unsourced ones are usually dropped from the total.

One published non-QM program guide gives a clear version of these rules:

• Transfers from personal accounts into the business account are excluded.
• Transfers from another business account need evidence that they are business-related.
• On personal statements, wages, fixed income, rental income, tax refunds and transfers between personal accounts are excluded.
• On business statements, deposits that do not match self-employment income, such as credit card refunds or IRS refunds, are excluded.
• Any single deposit above 50% of average monthly deposits needs a letter of explanation. If the funds cannot be sourced, the deposit is excluded.
• Overdrafts are capped at 3 NSF instances on 12 months of statements and 6 on 24 months.

In the hypothetical table, the $16,000 vehicle sale was above 50% of the $30,525 average monthly deposit. It needed a letter and was removed because it was not business income.

Before you apply, mark every transfer, refund and one-time deposit on your statements. Keeping personal money out of the business account makes the review faster.

What credit score and down payment are typical?

Published bank statement programs commonly start between 620 and 660 FICO, with the highest loan-to-value ratios reserved for stronger scores. A 10% down payment on a purchase is common at the top tier, while cash-out refinances usually cap lower. Lender guidelines vary, and approval is subject to underwriting.

Lender program (public page, Oct 2026)	Minimum credit score listed	Maximum LTV or CLTV listed	Other listed norms
A&D Mortgage, Bank Statement	620	90% purchase, 80% cash-out	3 months reserves, DTI up to 55% owner-occupied, 25% ownership
Angel Oak, Bank Statement	640 (up to 75% LTV)	90% with 720 FICO	Loans $150,000 to $4 million, 25% ownership
Angel Oak, Business Bank Statement Elite	660	90%	Business statements only, 2 years self-employed, 50% ownership

A 90% LTV means a 10% down payment. At a 640 score, Angel Oak's page lists 75% LTV, which means 25% down. Reserves are counted in months of the full housing payment and must come from documented assets.

How does a bank statement loan compare with full-doc, 1099 and P&L loans?

A full-doc loan qualifies you on the net income in your tax returns. A bank statement loan uses deposits instead. 1099 and P&L-only programs sit in between, using 1099 forms or a CPA-prepared profit and loss statement. The right fit depends on which document shows your income most accurately.

Fannie Mae's self-employed guideline treats anyone with a 25% or greater ownership interest as self-employed. It generally requires a two-year history, documented with two years of signed personal returns or IRS transcripts, plus business returns in some cases. One year of returns can work if the business has existed for five years and you have held a 25% or greater share for all five. The lender analyzes cash flow on Form 1084 or an equivalent.

Program	Income document	How income is figured	Typical history
Full-doc (Fannie Mae)	2 years of personal and, in some cases, business tax returns	Net income after deductions, through a cash flow analysis	2 years, or 1 year of returns with 5 years in business
Bank statement	12 or 24 months of statements	Eligible deposits minus an expense factor, divided by months	Often 2 years self-employed
1099-only	1 or 2 years of 1099s plus year-to-date earnings	1099 income minus an expense factor of at least 10%	2 years of 1099 income
P&L-only	12-month P&L prepared by a CPA or licensed tax preparer	P&L net income times ownership share, divided by 12	2 years, with at least 50% ownership

These program norms come from Fannie Mae's guideline and one published non-QM program guide. Under that guide, the P&L must be dated within 90 days of closing, and bank deposits cannot be more than 10% below the P&L's gross revenue.

If your returns show strong net income, check full-doc first. Bank statement and P&L programs exist for owners whose write-offs pull taxable income well below what the business earns.

Where the ability-to-repay rule fits

The federal ability-to-repay rule covers bank statement loans too. Lenders must consider 8 factors, including income or assets, monthly debts, debt-to-income ratio or residual income, and credit history. Income must be verified with third-party records, and the rule lists "financial institution records" as one acceptable type.

Most bank statement loans are non-QM. The CFPB explains that a qualified mortgage cannot have interest-only periods or a term longer than 30 years. Several bank statement programs offer one or both, such as Angel Oak's 40-year interest-only option.

What documents should you gather?

Expect to provide every page of 12 or 24 consecutive months of statements, proof that you own the business, and proof that it is active. Add a CPA or tax preparer expense statement if you want a factor below 50%, plus asset statements for the down payment and reserves.

1. Every page of 12 or 24 consecutive months of business or personal statements. One guide requires the most recent statement to be dated no more than 45 days before application.
2. 2 months of business statements if you qualify on personal statements.
3. Proof of ownership, such as a business license, articles of incorporation or a partnership agreement. Many programs require at least 25%.
4. A CPA, licensed tax preparer or bookkeeper expense statement, if you want a lower expense factor.
5. Proof the business is operating, such as a CPA letter, signed invoices or an active website. One guide dates this within 10 business days of closing.
6. Letters of explanation for large deposits, transfers and any NSF items.
7. Asset statements for your down payment, closing costs and reserves.
8. Government ID and authorization for a credit report.
