A bonus can make a meaningful difference to your household budget, especially when it lands regularly. But when you are working out how much you can borrow, the question is not simply whether you receive one. If you are asking, “can bonuses count income for a home loan?”, the more useful question is whether a lender sees that income as reliable enough to continue.
For many New Zealand borrowers, bonuses can be included in lending calculations. The catch is that each lender has its own policy, and the way your bonus is paid matters just as much as its size. A consistent annual performance bonus may be treated very differently from a one-off payment after an exceptional year.
Can bonuses count as income for a home loan?
Yes, they can, but lenders rarely count every dollar automatically. They need to understand the pattern behind the payment and decide whether it is likely to remain part of your income.
A lender will usually look for evidence that your bonus is regular, established and connected to your ongoing employment. If you have received a similar bonus over the past two or three years, that gives the lender a clearer basis for using it. If it is written into your employment agreement, even better, although a contractual entitlement does not always mean the full amount will be accepted.
Some lenders use an average of your previous bonuses. Others may apply a conservative percentage or only include the lower amount where your bonus has moved around. This is why a bonus of $20,000 does not necessarily add $20,000 to the income used for your application.
The approach also depends on the wider picture. A strong deposit, manageable existing debts, stable employment and clean account conduct can help support an application where part of your income is variable. On the other hand, if you are stretching to meet the lender’s affordability test, a lender may choose not to rely on bonus income at all.
What lenders want to see
Lenders are not trying to make life difficult. They are assessing whether repayments would still be manageable if your income changed. Bonuses, overtime and commissions are often treated cautiously because they can depend on company performance, individual targets or the wider economy.
To assess a bonus, a lender may ask for recent payslips, an employment agreement, an employer letter and your last one or two years of income evidence. This could include IRD income summaries, tax returns or bank statements showing the payments arriving in your account.
An employer letter can be particularly useful where it confirms how the bonus scheme works, how long you have participated, whether it is discretionary, and what you received previously. It does not need to promise a future bonus. In fact, an employer is unlikely to do that. It simply needs to give an accurate picture of the structure and your payment history.
Lenders will also consider whether the bonus is paid in cash, shares, profit distributions or another form. Cash bonuses shown on payslips are normally simpler to verify. Share-based incentives, deferred payments or bonuses that are retained by the employer can be more complex, even if they have real value to you.
Regularity matters more than one big year
A large bonus last year may look great on paper, but one strong result is not always enough. Say you received $5,000, $7,000 and $8,000 over three years. That history is usually easier to present than a single $30,000 bonus with no earlier pattern.
The same applies if you have recently changed jobs. Your previous bonus history may still help explain your earning capacity, but a new employer and new remuneration structure can mean the lender takes a more conservative view. Waiting until you have received your first bonus in the new role may improve the options available, though it depends on your overall application and the lender.
Discretionary does not mean impossible
Many bonuses are described as discretionary. That wording is common and does not automatically rule them out. The lender will look beyond the label to see whether the employer has paid bonuses consistently and whether your own history supports the income.
However, a discretionary payment that varies wildly or depends on a once-off event is less likely to be included. It is sensible to treat that money as a potential upside, not the foundation of the loan you need to buy your home.
Bonus income, commission and overtime are not identical
These income types are often grouped together as variable income, but they should not be treated as exactly the same.
Commission may be a central and ongoing part of a salesperson’s role. If it has a long history, lenders may accept a meaningful portion of it. Overtime can be accepted where it is regular and clearly shown across payslips, although industries with seasonal workloads can produce more variable results.
A bonus is often paid annually or quarterly and may be tied to company profits or performance targets. Because it arrives less often, the evidence needs to tell a convincing story over time. For a borrower with a base salary of $95,000 and a regular $15,000 annual bonus, the lender may assess the bonus as an averaged supplement to their main income. They may not treat it as a guaranteed monthly payment.
For self-employed borrowers, the same principle applies in a different form. A business may have an excellent year, but lenders usually want to see sustainable trading performance rather than rely on a single peak year. Financial statements, tax returns, business account conduct and the reason for any income changes all matter.
How to prepare before applying
The best time to think about bonus income is before you sign a sale and purchase agreement. A pre-approval can clarify how a lender is likely to treat your income and help you search within a realistic price range.
Start by gathering your evidence early. Keep your latest payslips, employment agreement, bonus letters and bank statements in one place. If your bonus is paid yearly, do not assume a recent payslip alone explains it. Supporting documents can make the history much easier for the lender to follow.
It also helps to keep your everyday banking tidy in the months before an application. Lenders will review living costs, debt repayments and account conduct alongside your income. Regular unarranged overdrafts, missed payments or new buy-now-pay-later balances can reduce borrowing capacity, even where your earnings are strong.
Be realistic about the repayment you can afford from your base salary. Building a home loan around a variable payment can leave you exposed if your employer changes the bonus programme or business conditions tighten. If the bonus is accepted, it may help you borrow more. If it is not, you still want a lending plan that keeps your goals moving.
The lender choice can change the outcome
There is no single rule that every bank and non-bank lender follows. One lender may accept an average of your two-year bonus history, while another may need three years or take a more conservative view of a new role. The right lender is not always the one advertising the lowest rate. It is the one whose policy fits your full financial position and supports a loan structure you can live with.
That is particularly relevant for buyers with mixed income, including a salary plus bonus, contracting income, rental income or a partner returning to work after parental leave. Presenting the application clearly from the start can save time and avoid the frustration of receiving a result based on incomplete information.
Mortgage Time works for you, not for one bank. We can assess how your bonus fits into the wider lending picture, identify the documents that will strengthen your application and help you understand your options before you make an offer.
A regular bonus can be a useful part of your home loan story, but it is strongest when backed by clear evidence and a repayment plan that still feels comfortable if the next payment is smaller. Getting that clarity early gives you more confidence when the right property comes along.
