"We need two years of tax returns." Every self-employed borrower in America has heard that sentence, usually delivered as though it were carved into a wall somewhere. For a large number of the business owners we talk to, it is simply not what the guideline says.

Fannie Mae permits a lender to use **one year** of tax returns when the business has existed **five years** and the borrower has held **25% or more** ownership, after the lender completes a cash flow analysis on **Form 1084**. That is a conventional loan. Conventional pricing, conventional mortgage insurance rules, agency execution.

If you have run a motel since 2013, a c-store since 2016, or a staffing company since 2018, this rule may be sitting there unused in your file.

## Why one year beats two for this audience

A two-year average is a blunt instrument. It treats a bad year and a good year as equally predictive, which is fine for a salaried borrower and often wrong for a business owner.

Business owners in our community take their hits in specific, explainable ways. The road in front of the store was torn up for eight months. The motel had a renovation year and ran at 40% occupancy. A staffing company lost a single large client and replaced it two quarters later. A restaurant carried a second location that did not work and was closed. In every one of those cases, the older year is the worse year and the newer year is the real business.

Averaging drags the newer year down toward a condition that no longer exists. One year does not.

## The math, on a motel

Take Mahesh, a composite of files we see in Orlando. He has owned and operated a 42-room motel since 2013. He owns 100% of the entity. His 2024 was a renovation year with two floors offline; 2025 was a full year of normal operation.

Qualifying income, both years run through Form 1084 with the required add-backs applied:

|  | **2024** | **2025** |
| --- | --- | --- |
| Qualifying income | $128,000 | $186,000 |
| Monthly | $10,667 | $15,500 |

| **Approach** | **Monthly income** | **45% DTI capacity** | **Less $1,100 other debt** | **Less $1,300 taxes and insurance** | **P&I supported** | **Loan supported** |
| --- | --- | --- | --- | --- | --- | --- |
| Two-year average ($157,000) | $13,083 | $5,887 | $4,787 | $3,487 | $3,487 | ~$526,700 |
| One year (2025 only) | $15,500 | $6,975 | $5,875 | $4,575 | $4,575 | ~$691,100 |

Loan amounts assume principal and interest of about $6.62 per $1,000 borrowed, which corresponds to the 6.95% 30-year fixed average reported in the Freddie Mac Primary Mortgage Market Survey for the week of **September 17, 2026**. That is a survey average, not a rate available to you.

**$164,400 of additional purchasing power**, from the same borrower, the same business and the same two tax returns. All that changed is which guideline path the lender used.

## The conditions, stated precisely

Two versions of this rule exist, and they are not the same. Know which one your file is running under.

**The manual version.** If the business has been in existence five years and the borrower has maintained 25% or more ownership consistently, the lender may obtain one year of returns and perform the cash flow analysis on Form 1084.

**The Desktop Underwriter version, per B3-3.5-01.** This is stricter. One year of personal returns is permitted only if ownership is 25% or greater **and** "the Start Date for all self-employed businesses is at least five years prior to the Casefile Create Date." If that condition is not met, DU requires two years. Most conventional files run through DU, so in practice this is the version that governs.

Read that language once more. **All** self-employed businesses. Not the main one. If you have run the motel since 2013 and also started a small trucking LLC eighteen months ago, the eighteen-month entity can break the test for the whole file.

## What "Start Date" actually means

The start date is when the business began operating, and the lender has to document it. In practice that comes from one or more of:

- The Secretary of State formation date for the LLC or corporation.

- The business license or local permit, which matters for fuel, alcohol and food service.

- A letter from your CPA or tax preparer stating when the business began.

- The earliest tax return on which the business appears.

Where these disagree, expect the underwriter to take the most conservative date. If you operated as a sole proprietor from 2013 and formed an LLC in 2021, the documentation needs to show continuity of the same business — same operation, same location, same line of work — rather than a new venture that started in 2021.

This is the point where files quietly fail, and it is avoidable. Get your formation documents and a CPA letter into the loan officer's hands in the first week.

## Partnerships and S corps: confirm your percentage

If you own a restaurant with two cousins, or a motel with a partner, you need to know your actual ownership percentage and be able to prove it. The 25% threshold is not a formality.

Your ownership shows on the **K-1** from **Form 1065** for a partnership or **Form 1120S** for an S corp, and it should match the operating agreement. Three things go wrong regularly: the operating agreement was never updated after a partner bought in or out; the K-1 percentage reflects a profit-sharing split rather than ownership; or the percentages across all partners do not total 100%.

Sort that out before you apply. And remember that for partnerships and S corps, **B3-3.2-02** requires the lender to confirm actual cash distributions received, not just the income reported on the K-1 — the mechanics are in [K-1 Income, Distributions and the Restaurant Partnership](https://masalaloans.com/blog/k1-income-partnership-mortgage-qualifying).

## Test this path before anyone sells you a non-QM loan

A conventional loan is generally better priced than a bank statement loan. It also carries mortgage insurance that can be removed later, conforming loan limits of **$832,750** on a one-unit property in 2026 with a high-cost ceiling of **$1,249,125**, and none of the reserve and LTV constraints that non-QM investors attach to their programs.

The order of operations is the same one described in [Your Tax Return Says $40,000](https://masalaloans.com/blog/low-taxable-income-high-revenue-mortgage): run the add-backs, then test the five-year rule, and only then price a [bank statement loan](https://masalaloans.com/blog/how-bank-statement-loans-work). A borrower who lands in non-QM because nobody tested the five-year rule is paying a premium for a document problem that did not exist.

Ask your loan officer one question: "Did you run this as a one-year self-employed file under the five-year business rule, and what did DU return?" The answer tells you a great deal about who you are working with.

## Do not do this

Do not restructure your entity in the year before you apply. Converting a sole proprietorship to an LLC, or an LLC to an S corp, can produce a new Start Date in the file, and a new Start Date can put you back under the two-year requirement. If the restructure is worth doing for tax or liability reasons, do it after you close, and talk to your CPA and your attorney about timing.

Also do not open an unrelated side business while your file is in underwriting. A new self-employed entity that appears mid-process can break the DU condition that all self-employed businesses be at least five years old.

## Frequently Asked Questions

**Q: Can I get a conventional mortgage with only one year of tax returns?**<br />A: Yes, in defined cases. Fannie Mae allows one year of returns when the business has existed five years and you have held 25% or more ownership, after a cash flow analysis on Form 1084. Under Desktop Underwriter, per B3-3.5-01, the start date for all of your self-employed businesses must be at least five years before the casefile create date.

**Q: What is the five-year business rule for self-employed borrowers?**<br />A: It permits a lender to rely on a single year of tax returns rather than two, when the business has five years of existence and consistent 25%+ ownership. The purpose is to avoid penalizing a long-established business for one weak year by averaging it with a strong one.

**Q: Does a second small business break the five-year rule?**<br />A: Under Desktop Underwriter it can. The condition applies to the start date of all self-employed businesses, so a newly formed side entity can push the file back to a two-year requirement even when the primary business is fifteen years old. Discuss any recently formed entity with your loan officer before applying.

**Q: Is one year of returns better than a two-year average?**<br />A: Only when your most recent year is stronger. If the recent year is weaker, the average is usually the better number and the one-year path does not help. Have your loan officer calculate both on Form 1084 and use whichever supports your file honestly.

**Q: How do lenders prove when my business started?**<br />A: Through the Secretary of State formation date, a business license or permit, a CPA letter stating the start date, and the earliest tax return showing the business. Where these conflict, underwriters generally take the most conservative date, so gather the documents that show continuity of the same operation.
