How Different Lenders Assess Self-Employed Income

Self-employed borrowers represent a growing segment of the New Zealand workforce, and helping them secure mortgage finance is one of the more nuanced parts of a broker's role. Unlike salaried applicants, self-employed clients rarely have a single, clean income figure to present. The way lenders interpret their financials varies considerably, which means understanding each lender's methodology is just as important as understanding the client's numbers.

The Core Challenge: What Is Stable Income?

For salaried employees, income verification is relatively straightforward. For self-employed clients, lenders are trying to identify a sustainable, ongoing income from financial statements that may reflect business decisions, tax minimisation strategies, or uneven trading periods. The challenge is that two lenders can look at the same set of accounts and reach quite different conclusions about serviceability.

Most lenders require at least two years of financial statements, including both personal and business returns, together with the most recent tax assessments. Some will consider one year of trading where the self-employment is in the same field as prior PAYE employment, though this is assessed case by case. The key is that brokers need to know each lender's minimum documentation requirements before packaging an application.

After-Tax Profit vs Add-Backs

One of the most significant differences between lenders is how they treat add-backs. Depreciation, one-off expenses, and certain drawings can sometimes be added back to net profit to arrive at a more accurate picture of cash available for debt servicing. Some lenders apply a standard set of add-backs consistently; others take a more conservative approach and base serviceability strictly on net profit after tax.

Brokers should request clear policy guidance from each lender's credit team or BDM on which add-backs are acceptable. Using add-backs that a particular lender does not recognise will result in declined applications or conditional approvals that frustrate the client. Understanding these differences in advance allows you to select the right lender from the outset rather than repackaging after a decline.

Averaging Income Over Multiple Years

Where a client's income has fluctuated, lenders will generally average the last two years of net income. If income has been declining, many lenders will use the most recent year's figure rather than the average - a conservative approach designed to reflect the client's current earning capacity. Where income has been increasing, some lenders will recognise the trend and use the higher figure, while others remain anchored to the average.

For clients who have had an unusually strong or weak trading year due to specific circumstances, it is worth preparing a brief client letter explaining the variation. Lenders differ in how much weight they place on narrative context, but providing it is generally better than leaving a credit analyst to draw their own conclusions.

Company Structures and Trust Income

Many self-employed clients operate through a company or trust structure, which adds another layer of complexity. Retained earnings in a company are not always treated as accessible income, and trust distributions may require evidence of consistency and the trustee's discretion to continue paying them. Some lenders are more comfortable assessing complex structures than others, and placing these clients correctly from the start saves significant time.

Where a client has salary drawn from their own company, lenders will typically want to confirm that the business has the capacity to sustain that salary. This usually means reviewing both personal and company financials together. Brokers working regularly with business-owner clients benefit from building familiarity with lenders whose credit teams have experience in this space.
