How Many Years of Tax Returns Does a Self-Employed Mortgage Need?

The Quick Read: It depends on the loan type. A conventional mortgage defaults to two years of personal and business returns, while bank statement loans swap returns for 12 months of deposit history through select lenders in Lendmire’s network, and DSCR investor loans generally leave personal returns out of the file.

• Conventional loans: two years of returns is the default, with narrow one-year exceptions.
• Bank statement loans: 12 months of business or personal statements replace the return history.
• DSCR loans: the property’s rent against the full housing payment drives the file.
• Returns count and self-employment history are two separate tests.
• Write-offs that cut taxable income also cut the income a return-based loan can use.

Most borrowers ask this question with a specific problem in mind. Either the business is new, or last year’s return shows far less income than the business really produced. The answer changes depending on which door you walk through.

The Straight Answer by Loan Type

Two years is the default only on one path. Three different documentation paths exist, and each asks for something different.

Across Lendmire’s wholesale network, the pattern is consistent. Return-based programs ask how much net income your tax filings show. Bank statement programs ask how much money moves through your accounts. DSCR programs ask whether the rental property carries itself. Those are different questions, so they need different paper.

Why Lenders Ask for Two Years on a Conventional File

Lenders want proof the income repeats. One strong year can be a one-off contract. Two years show a trend, and underwriters average the figures to smooth out spikes and dips.

Fannie Mae’s Selling Guide announcement SEL-2023-09 says self-employment income is documented with the two most recent years of personal and business returns. The same announcement allows one year when the business has existed for five years and the borrower has held at least 25% ownership for five consecutive years. It also allows a shorter history when returns show at least 12 months of income from the current business.

That is a contrast point only. Agency rules do not govern the bank statement or DSCR programs discussed below. They explain why so many self-employed borrowers go looking for another route.

Two years is an underwriting standard, not a law. Programs set their own documentation rules, and that is the whole reason alternatives exist.

What the Return Review Actually Looks Like

On a return-based file, the lender does more than read your returns. It verifies them with the IRS.

1. The borrower signs a Form 4506-C for each person whose income counts. Fannie Mae’s transcript documentation requirements say the form can pull transcripts for up to four tax years and stays valid for 120 days.

2. One tax form can be requested per 4506-C. A borrower with personal and business returns for two years ends up signing several forms.

3. The underwriter calculates income from net profit, not gross revenue. Lenders commonly use the lower of the two years, and a sharp year-over-year drop draws questions.

4. A year-to-date profit-and-loss statement and business bank statements may be requested on top of the returns.

Here is the catch for investors. Depreciation, aggressive write-offs, and Schedule E rental losses lower the net figure on the return. Smart tax planning and strong mortgage income pull in opposite directions. Ask a lender about this before you file, not after.

How Returns Turn Into Qualifying Income

Take a modeled example with round, made-up figures, not market data. Say a borrower’s business shows 100 units of net income in year one and 100 in year two. The lender averages to 100, a steady figure.

Now change year two to 70. The lender will probably qualify on the lower, declining figure, or on an average that sits well under what the business earned in its best year. A decline can also bring a letter of explanation or a request for more recent documentation.

Now flip it. Year one is 70 and year two is 100. Averaging gives 85, which understates where the business is today. Some lenders will weigh the rising trend, but plan on the average being your number.

That is why a growing, well-run business can look weaker on paper than it is. It is also why bank statement lending exists.

Do You Count as Self-Employed?

Usually the answer is yes if you own 25% or more of a business or earn income reported on a 1099 rather than a W-2. Rules vary by program. Mixed income, such as a W-2 job plus a side business, can still trigger a self-employed review of the side income.

Which Returns Go With Which Business Type

Sole proprietors and single-member LLCs usually report on Schedule C within the personal return. Partnerships and S-corporations file separate business returns, and owners receive a K-1. On a return-based file, expect the lender to ask for both the personal return and the business return when income is part of the qualifying figure. The entity type decides which pages matter most.

When You Haven’t Been Self-Employed Long

A short history is the exception on a conventional file, and it needs support. Per the same SEL-2023-09 announcement, returns showing at least 12 months of income from the current business open that door. Prior work in the same field or a similar occupation helps the case.

Keep two tests separate:

• History: how long you have been self-employed.
• Returns: how many filed returns the lender wants to see.

A borrower can pass one and fail the other. Someone 18 months into a business has a history problem on a conventional file and a return-count problem too, because the first return may cover only a partial year. Partial-year returns are the awkward edge case, and they are where bank statement documentation tends to fit better.

When a Lender Asks for More Than the Minimum

Extras show up when the file looks uneven. Common requests:

• A letter explaining a down year.
• A year-to-date profit-and-loss statement.
• Business bank statements to confirm the returns.
• Proof of filing, or an extension, if the latest return is not done.

Timing matters here. If you have not filed the most recent return, the lender has to decide which year is the latest complete one. Talk to the loan officer before the filing deadline, not after it passes.

Options When Returns Don’t Show Your Income

Bank statement loans are the main alternative. Across the programs Lendmire’s network works with, they qualify on documented income under the applicable program, subject to lender guidelines. The standard documentation is 12 months of business or personal bank statements. Lenders total eligible deposits, then apply an expense factor to reach qualifying income. Expense factors differ by lender, so no universal formula exists.

Leverage depends on the transaction and the occupancy:

Stronger files earn the top of each range. On owner-occupied cash-out, the lender applies a fixed expense ratio to deposits, and the 80% ceiling applies to that fixed ratio. When an accountant prepares the expense ratio, the ceiling is 75% instead. Loan size and credit also affect where a file lands in either case. Investment purchase leverage on bank statement documentation 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. All of it is subject to lender guidelines and credit review. Term length follows each lender’s program sheet.

HousingWire’s non-QM guide describes the same toolbox: bank statements over 12 to 24 months, 1099 programs that use one to two years of 1099s depending on the program, CPA-prepared profit-and-loss loans, and DSCR loans that compare rent to the housing expense. Which one fits depends on how your income shows up.

Owner-occupied files are consumer mortgages, so TRID disclosure rules apply. A bank statement loan on a non-owner-occupied rental is business-purpose and exempt from TRID. The property’s occupancy decides which regime governs.

The Investor Decision: Returns, Statements, or the Property

If the purchase is a rental, the cleanest question is whether your personal income needs to be in the file at all. DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage. The file turns on rent against the full housing payment, credit, equity or down payment, and reserves. Lendmire’s complete DSCR loans guide walks through those mechanics.

Less paperwork does not mean none. Expect an appraisal or rent analysis, entity documents, identity and credit documents, and proof of assets. Select lenders in the network also review programs below a 1.00 coverage ratio, though leverage and terms adjust when they do.

For a self-employed investor, the practical split looks like this:

• Buying a home to live in: returns or bank statements, depending on how your write-offs affect net income.
• Buying or refinancing a rental: DSCR is usually the more natural fit because the property carries the file.
• Pulling cash from a primary residence: owner-occupied cash-out on bank statements, with the 80% ceiling in mind.

Lendmire’s article on how many years you have to be self-employed to get a mortgage covers the history test. Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
