How long you have earned it
A history of receiving variable income can make it easier to show that the earnings are a regular part of your overall income.

Income and Qualification
Can Overtime, Bonus or Commission Income Be Used for a Mortgage?
Your base salary may only tell part of the story. If overtime, bonuses, commission, shift premiums, or other variable earnings make up a meaningful part of your income, the amount a lender can use may be different from the amount you actually earn.

The Situation
Your salary may not be your whole income.
Maybe your employment letter says you earn $70,000 a year, but your actual income is higher because overtime is a regular part of what you earn.
Or part of your income may come from annual bonuses, commission, shift premiums, or another source that changes from year to year.
That extra income may still be usable for mortgage qualification. The question is how much of it the lender can reasonably support.
A Common Example
“I earn more than my base salary. Does the rest count?”
Base salary
$70,000
Regular overtime
Varies
Actual income
Higher
The qualifying income may be higher than the base salary.
But the latest total-income figure should not automatically be assumed either. The amount used will depend on what the income history supports.
How It May Be Reviewed
Variable income usually needs some history behind it.
When income changes from year to year, the lender may look at the pattern over time before deciding what amount can reasonably be used for qualification.
How consistent it has been
The lender may compare multiple years rather than relying only on your most recent or highest-income year.
Whether it appears likely to continue
Your current employment, role, pay structure, and recent earnings can all help provide context for the income history.
How the income can be documented
Tax documents, pay information, employment documents, and other records may be needed depending on the income source and lender.
For overtime, I would generally plan on needing a two-year history.
Other types of variable income can be reviewed differently, and the amount that can be used may vary by lender, insurer, income type, and the overall application.
Not All Variable Income Looks the Same
Overtime, bonuses, and commission can each tell a different story.
The income may all appear on the same tax return, but the lender can still look at where it came from, how long it has been earned, and how consistently it has been received.
Overtime
Regular overtime may be used for mortgage qualification when there is a consistent history of receiving it.
- In most cases, I would plan on needing a two-year history.
- The lender will look at what the overtime income has actually been over that period.
- A recent increase in overtime does not automatically mean the higher amount can be used.
Bonuses
A recurring bonus may be used for mortgage qualification when there is enough history to support it.
- In most cases, a two-year history is a good expectation.
- The lender may compare the most recent year with the income received over the previous two years.
- A new bonus or one-time exceptional payment may not have enough history to be relied on.
Commission
Commission income can be used for mortgage qualification, but the income history becomes especially important.
- In most cases, I would plan on providing at least two years of commission income history.
- The amount used may be based on the documented income over that period rather than the latest paycheque or current run rate.
- How you are employed and how the commission is documented can affect what the lender requires.
A Simple Example
The latest income number is not always the qualifying income number.
Imagine someone has a $70,000 base salary but regularly earns overtime throughout the year.
Their total income has been rising. That is positive, but the lender may still want to understand the pattern rather than simply using the highest number.
Base salary
$70,000
Current guaranteed salary
2024 income
$88,000
Includes overtime
2025 income
$94,000
Includes overtime
So what income gets used?
It may be more than $70,000, but $94,000 should not automatically be assumed either. The amount used will depend on what the income history supports.
This example is for illustration only. Actual income treatment can vary by lender and application.
When Income Is Changing
What if this year is much better than last year?
Sometimes the complication is not that your income is inconsistent. It is that your income has recently improved.
Maybe you were promoted, started receiving more regular overtime, moved into a stronger commission role, or began earning a larger recurring bonus.
Your current earnings may be stronger than the income history available to support them today.
The increase still matters, but timing can affect how quickly it becomes useful for mortgage qualification.
You are earning more
Your current pay may now be noticeably higher than the income shown in previous years.
Your role changed
A promotion, new position, or different compensation structure can change the income picture quickly.
The increase is recent
The challenge may simply be that the stronger income has not been in place long enough to create much history yet.
Timing can matter just as much as the amount.
If your income has recently increased, it can be worth reviewing the mortgage numbers before assuming that either the old income or the new income will automatically be used.
Not Sure What Income Can Be Used?
I can help you look at the income history before you plan around the wrong number.
If you know your recent income, how it is earned, and roughly what the last two years looked like, I can help you get a clearer idea of what a lender may be able to use.
Common Questions
A few things people often want to know.
Variable income can raise a few extra questions. These are some of the ones that come up most often.
In most cases, I would plan on needing a two-year history if overtime is going to be used for mortgage qualification. Lenders generally want to see that the overtime has been received consistently over time rather than relying on a short period of higher earnings. There can be differences between lenders and individual applications, but in practice, using overtime with less than two years of history can be difficult.
Potentially. A bonus that has been received regularly may be treated differently from a new bonus program or a one-time payment.
Yes. Commission income may be used for mortgage qualification. The amount available for qualification will depend on the income history and how the commission is earned and documented.
The increase still matters, but a recent jump in income may not immediately translate into the same increase in qualifying income. The timing and reason for the change are worth reviewing.
The exact documents depend on the income source and lender. Pay information, employment documents, tax slips, Notices of Assessment, and other income records may be requested.
Yes. If a refinance depends on variable income, it is worth confirming what income can realistically be used before planning around the amount of equity you want to access.

A Note From Kiersten
Your income does not always fit neatly into one box.
If part of what you earn comes from overtime, bonuses, commission, shift premiums, or another variable source, do not assume it will not count. And do not assume all of it will count either.
I can look at how you are paid, your income history, and the documents available, then help you understand what may realistically be used before you plan around a purchase or refinance.
