How Mortgage Lenders Calculate S-Corporation Income

For an S-Corporation owner, qualifying for a mortgage isn't as simple as presenting a pay stub. Lenders perform a detailed analysis of both your personal and business financials to establish a stable, reliable income figure. This process involves looking at two primary sources: your W-2 salary and the business's net income.

First, lenders review your W-2 salary, the amount you pay yourself as a formal employee of your S-Corp. This is the most straightforward part of the calculation. They will verify this using your personal tax returns and recent pay stubs.

Second, they analyze the business's profitability through the Schedule K-1 (Form 1120-S). The K-1 shows your share of the corporation's income, losses, deductions, and credits. A lender’s underwriter starts with the ordinary business income (or loss) reported on the K-1 and then makes specific adjustments. They are trying to determine the company's true cash flow and how much of that profit is available to you without negatively impacting the business's operations.

Typically, lenders will request the last two years of both personal and business tax returns to calculate a 24-month average income. This demonstrates stability to the underwriter. If your income has increased, they may use a 12-month average, but a declining income trend is a major red flag and will likely result in them using the lower, more recent figure.

Salary vs. Distributions: What Matters for a Loan?

This is the central dilemma for many S-Corp owners. To minimize self-employment taxes (Social Security and Medicare), you might pay yourself a modest 'reasonable salary' via W-2 and take the rest of the profits as distributions. While this is a smart tax strategy, it can create challenges for mortgage qualification if not managed correctly.

From a lender's perspective, both components matter, but they are viewed differently:

S-Corp owner reviewing financial documents for a mortgage.

Example:

Imagine you own a successful consulting firm in San Diego. In 2022 and 2023, you paid yourself a W-2 salary of $60,000 to reduce FICA taxes. The business's net profit after all expenses (including your salary) was $150,000 each year, and you took that full amount in distributions.

An underwriter would typically calculate your qualifying income like this:

However, if you took distributions of $200,000 while the business only profited $150,000, the lender would only use the $150,000 figure. They will not use distributed income that exceeds the company's actual earnings for that period.

The key is consistency. Erratic, large, one-time distributions are less favorable than a track record of steady, supportable distributions combined with a reasonable salary.


The Impact of Retained Earnings on a San Diego Mortgage

Retained earnings are the profits you deliberately leave in the business for growth, cash flow, or future investments. This is a prudent business practice, especially for companies that need to manage inventory or plan for capital expenditures. However, for mortgage qualification purposes, retained earnings are not counted as your personal income.

Lenders are concerned with the cash that is actually available to you to pay the mortgage. Money left in the business operating account is considered the business's asset, not yours. If you claim that income, the underwriter will need to see proof that withdrawing it would not harm the business. A business liquidity test might be performed by analyzing balance sheets and profit and loss statements. (The data, information, or policy mentioned here may vary over time.)

For instance, if your retail business in La Jolla needs to maintain $100,000 in cash for seasonal inventory purchases, you cannot present that $100,000 as part of your qualifying income. An underwriter will recognize it's essential for the company's ongoing operations. Attempting to count retained earnings often results in the lender disallowing it, reducing your total qualifying income.


Can I Add Back Paper Losses to My Qualifying Income?

Yes, and this is one of the most significant advantages for self-employed borrowers. Your business's net income on paper is often lower than its actual cash flow due to non-cash expenses, also known as 'paper losses'. Underwriters are trained to identify these and add them back to your net profit, increasing your qualifying income.

Common add-backs for an S-Corporation include:

Example of Add-Backs in Action:

Let's say your San Diego-based S-Corp's tax return shows a net profit of $120,000.

An underwriter would calculate your adjusted business income as:

$120,000 (Net Profit) + $25,000 (Depreciation) + $5,000 (Amortization) = $150,000

In this case, your qualifying income from the business is $30,000 higher than what the bottom line of the tax return suggests. This can make a substantial difference in the loan amount you qualify for.


How Many Years of Tax Returns Are Needed?

The industry standard for documenting S-Corporation income is a two-year history. Lenders require the most recent two years of complete, filed personal tax returns (Form 1040) and business tax returns (Form 1120-S), including all schedules like the K-1.

This two-year lookback period allows underwriters to:

  1. Establish Stability: They can see if your income is consistent, increasing, or declining.
  2. Calculate an Average: They typically average the income over 24 months to smooth out any fluctuations.
  3. Verify Business Health: Reviewing two years of returns provides a clearer picture of the company's long-term viability.

In some limited circumstances, a lender might consider just one year of tax returns. This is generally reserved for strong files where the business has been established for at least five years and other compensating factors are present, such as excellent credit, a large down payment, and substantial cash reserves. However, for most S-Corp borrowers, especially those in competitive markets like San Diego, planning to provide a full two-year history is the safest approach. (The data, information, or policy mentioned here may vary over time.)


Structuring Pay for Jumbo Loans in La Jolla

Jumbo loans, which are mortgages that exceed the conforming loan limits set by the FHFA, come with more stringent underwriting requirements. For high-value real estate markets like La Jolla, where jumbo loans are common, lenders scrutinize an S-Corp owner's income even more closely.

When preparing to apply for a jumbo loan, the 'low salary, high distribution' strategy becomes riskier. Jumbo underwriters place a premium on predictable, documented income. A higher, more consistent W-2 salary is viewed much more favorably than large, irregular distributions.

Consider increasing your W-2 salary to a level that more closely reflects your total compensation for at least the 24 months leading up to your mortgage application. This demonstrates a stable financial base capable of handling a larger mortgage payment. While it may mean paying more in FICA taxes temporarily, it significantly strengthens your loan application and increases your chances of approval for a higher loan amount. (The data, information, or policy mentioned here may vary over time.)


Advising Your Accountant Before a Home Purchase

Your accountant or CPA is your partner in tax strategy, but their primary goal is often to minimize your tax liability. This can be at odds with the goal of maximizing your qualifying income for a mortgage. It is essential to communicate your homebuying plans with them 12 to 24 months in advance.

Here are key points to discuss with your accountant:
