Can Schedule K1 Income Be Used to Qualify for a Mortgage?

Ownership percentage changes the underwriting category

Schedule K1 income is one of the most misunderstood areas of mortgage qualification because the same tax form can appear in very different borrower profiles.

Under Fannie Mae’s October 2026 guidance, a borrower with less than 25% ownership of a partnership, S corporation or LLC can be evaluated under a specific K1 income rule. At 25% ownership or more, you are treated as self employed and the broader self employment analysis applies.

That single ownership threshold changes the documentation and the depth of business analysis the lender may need.

For less than 25% ownership, Fannie Mae generally wants two years of K1 history

The current rule requires the most recent two years of signed personal federal tax returns and Schedule K 1s for ordinary K1 income under 25% ownership. A verbal verification of employment is also required when the K1 income is being used, except in the special case where only rental income is reported on the K1.

Fannie Mae lists a minimum two year income history for this category.

Taxable K1 income isn't automatically usable cash flow

A K1 can report income that was allocated to you for tax purposes even when you didn't actually receive the cash. Mortgage underwriting therefore asks a second question: can the borrower really access the earnings being used to qualify?

Fannie Mae allows the income when the lender can verify either that the income was actually distributed to you at a level consistent with the qualifying income or that the business has adequate liquidity to support the withdrawal of earnings.

Example: $80,000 of K1 income with only $10,000 distributed

Assume you own 15% of an S corporation and the K1 reports $80,000 of income. If only $10,000 was distributed and the business retains the rest, the lender can't simply divide $80,000 by 12 and call it $6,667 of monthly qualifying income without addressing access to those earnings.

If the lender can document that the business has adequate liquidity to support distributions, more of the K1 earnings may be usable. If the business can't support the withdrawal, the tax form alone doesn't solve the problem.

Guaranteed payments can be especially valuable

Fannie Mae permits guaranteed payments to a partner to be added to cash flow when you have a two year history of receiving them. These payments can be more straightforward because they represent compensation paid to the partner rather than merely allocated pass through income.

The October 2026 guidance also includes an important exception for some professionals who recently acquire nominal ownership in a professional services partnership after an established employment history with that partnership. In that situation, guaranteed compensation may be supportable with the partnership agreement and current year to date income even without a full two year guaranteed payment history.

This can matter for physicians, attorneys and other professional partnerships

A physician who becomes a small partner in a medical practice or an attorney who receives a nominal partnership interest may suddenly start receiving a K1 even though the underlying work and compensation relationship has existed for years. Treating that borrower as though the entire income history started on the date of partnership could misrepresent the stability of the earnings.

The newer Fannie Mae framework gives lenders a clearer path to recognize established compensation in qualifying professional services cases when the required documentation supports it.

Rental only K1 income has a narrower documentation path

When the Schedule K1 reports only rental income, Fannie Mae’s current rule allows one year of signed personal tax returns plus the K1, and a verbal verification of employment isn't required for that rental only K1 income.

That doesn't mean every rental property issue disappears. Rental income still has its own calculation and property related requirements. The point is that the K1 documentation requirement is different when the form reports only rental income.

Less than 25% ownership doesn't require the same business viability analysis as self employment

For the specific under 25% K1 rule, Fannie Mae says the lender isn't required to perform the full business viability analysis that applies to self employed borrowers. The lender may use the borrower’s proportionate share of earnings shown on the K1, subject to the distribution or liquidity requirements.

That is a major reason to classify ownership correctly before assuming a complex self employment file is required.

At 25% ownership, stop using the shortcut

Once you own 25% or more of the business, Fannie Mae considers the borrower self employed. The lender may need personal and business tax returns, cash flow analysis, trend analysis and review of business liquidity depending on the file.

That is a different article and a different underwriting exercise. Self Employed Jumbo Mortgages: Qualifying With Business Income discusses self employed jumbo borrowers, and future conventional self employment content should cover the agency specific analysis in more detail.

What to gather before the lender calculates K1 income

• The most recent two years of personal tax returns and K 1s when required.
• Documentation of ownership percentage.
• Evidence of cash distributions received from the business.
• Partnership or operating agreements when they clarify ownership or guaranteed compensation.
• Current year to date income documentation for applicable professional partnership cases.
• Business liquidity documentation when distributions don't clearly support the earnings being used.

Bottom line

Schedule K1 income can be excellent qualifying income, but the lender needs to know whether you own 5%, 20% or 40% of the company and whether the income on the tax return is actually accessible. Under 25% ownership, current Fannie Mae guidance provides a more targeted path. At 25% or more, the file becomes a self employment analysis.
