How Do Lenders Count Commission, Bonus, or Overtime Income?

Why lenders treat variable income differently

Mortgage underwriting is built on one question about every dollar of your income: how likely is it to keep coming? A salary repeats every pay period with very little question. Commission, bonus, and overtime income can be strong one month and thin the next, so lenders apply a different standard: the income has to be reasonably likely to continue, and the best evidence of that is a stable, documented history.

The CFPB's mortgage key terms makes the same point in plain language: annual income for a mortgage application may include tips, commissions, overtime, and bonuses, but whether a lender will rely on a given income source depends on whether that income can reasonably be expected to continue. That is the whole rule in one sentence. Underwriting rewards income that repeats and penalizes income that could evaporate, no matter how impressive any single year looks.

The two-year rule for commission, bonus, and overtime

The most common guideline is a two-year history. Fannie Mae's Selling Guide section on bonus, commission, overtime, and tip income, for example, requires a minimum two-year history for these income types before they can be used for qualifying. That section is a reliable primary source for the conventional side of the market, and the general shape of the rule shows up across programs: history first, averaging second.

How lenders average the income

With a documented history in hand, lenders typically add up the variable income over the period and average it. If the history is two years, the lender averages over two years, not over your best year and not over your latest month. The average is what counts, which is good news when your earnings are climbing and honest when they have dipped: a $25,000 commission year followed by a $15,000 commission year produces a qualifying number in between, not at the peak.

What if only one of two years shows it?

Less history means less to average, and lenders respond conservatively. Commission, bonus, or overtime income that appears in only one of the two years may be excluded entirely, reduced to the amount supported by the documented history, or counted only where a specific program allows a shorter history, typically at least 12 months of documented, stable income. These are the "exceptions some programs allow," and they are exactly the kind of detail that varies by lender and loan program, so the honest answer for your file comes from running it, not from a rule of thumb.

How each income type is verified

Verification is where the average takes shape. The documents depend on the type of income, and the general pattern is the same everywhere: show the lender the history, then confirm it is likely to continue.

Commission income

Commission is commonly verified with pay stubs, often a year-to-date earnings statement, plus tax returns or W-2s for the prior years that show the same income pattern. The lender checks that the year-to-date figure lines up with what prior years suggest, which is why a strong first half of the year alone is not enough without the history behind it.

Bonus and overtime income

Bonus and overtime are typically verified through your pay history, usually the last two years of pay stubs and W-2s, plus an employer verification that confirms how your pay is structured and whether the income is expected to continue. Overtime that has been steady for two years averages up; overtime that only shows up sporadically, or has started to trail off, gets a harder look.

Freddie Mac's Seller/Servicer Guide section on employed income documentation is a good primary reference for how the employment verification side of this works. The takeaway for you: keep the paper trail. Two clean years of records make every one of these verifications faster and simpler.

How it combines with your base salary

Your qualifying income is built from the pieces together: base salary plus the averaged variable income, minus anything the lender decides not to count. The result is a total qualifying income that can sit above your base alone, which is the whole point, and it can also sit below your best year, because the lender is designing for the future, not celebrating the past.

Lenders may also use a conservative figure on purpose. A commission average that includes a thin year, overtime with a declining trend, or a variable income stream that barely clears the two-year mark can all push the usable number below the raw average. When you compare what you qualify for against what you expected, this is usually why. Nothing is wrong with your file; the lender is just being careful about which dollars it is willing to count.

What can hurt your case

Variable income most often gets reduced or excluded for a handful of predictable reasons. Knowing them ahead of time means you can talk about them before they surprise you at the application table.

A job change to a new commission structure

A new role with a new commission plan restarts the clock on your history in that structure. Your past commission doesn't automatically transfer to a job you just started, because the lender can't verify that the new plan will produce like the old one.

Declining overtime

If your overtime hours have been falling year over year, the lender sees a trend, and the average it counts may be based on the lower, more recent figure, or the overtime may be excluded altogether. Consistency is what underwriting pays for.

A recent change in your industry

Layoffs, a commission-restructuring announcement, or an industry slowdown in your line of work can make a lender question whether variable income will continue, even when your personal numbers look strong. It is a fair question, and it's worth being ready to answer it.

Relying on a one-time signing bonus

A signing bonus is a classic one-time payment: it is not recurring, it has no history behind it, and lenders generally won't count it as qualifying income. If your plan depends on that bonus for your down payment or your budget, treat it as cash, not as income.

Tips to prepare before you apply

Variable income is very usable when it comes with a story the documents can tell. Here is how to make that story easy to read.

Keep two years of records that show the pattern

Pay stubs, W-2s, and tax returns that show commission, bonus, and overtime in the same places year after year are the strongest evidence you can bring. Gather them before you apply, and keep the files in one place, digital copies are fine.

Hold steady employment in the same line of work

Two years in the same field and the same kind of role makes the "likely to continue" question nearly automatic. A mid-application move to a brand new industry or pay plan is the single most common reason a strong variable income picture gets reset.

Ask how your specific pay mix will be counted before you shop

Every lender and program applies these rules a little differently, and the exact averaging method matters to your number. Before you shop homes, ask a loan officer how your commission, bonus, and overtime would be treated: what gets averaged, what gets excluded, and what documents you'll need. That one conversation saves you from pricing homes against income the lender won't count.

An illustration: how averaged commission changes what you can consider

Numbers are easier to feel with an example. Everything below is an illustration, not a quote and not a preapproval, and every assumption is listed under the table. The goal is to show how a two-year average, not a single year, becomes the number a lender works with.

Key takeaways

• Lenders can count commission, bonus, and overtime income, but they generally want a two-year history and average the income over that period, so consistency beats any single great year.
• Qualifying income combines your base salary with the averaged variable income, and lenders may use a conservative figure when the trend is down or the history is thin.
• Verification runs through pay stubs, W-2s and tax returns, plus employer verification, so two clean years of records make your file easy to review.
• Job changes to a new pay structure, declining overtime, and one-time bonuses are the common reasons variable income gets reduced or excluded, so ask how your specific pay mix will be counted before you shop.

Frequently asked questions

How long do I need to have earned commission for it to count?

The most common guideline is a two-year history of receiving it, and some programs allow as little as 12 months of documented, stable income in specific situations. What matters beyond the time is the pattern: commission that is consistent and reasonably likely to continue counts far more than a shorter, spottier history.

Does a raise count as income?

Yes. A raise to your recurring base salary counts at the new rate once it is documented, typically with a recent pay stub and employer verification, because it is ongoing and can reasonably be expected to continue. A one-time signing bonus is the opposite: it is not recurring, and lenders generally will not count it as qualifying income.

Can overtime count if it's not guaranteed?

Yes, overtime can count even though it is not guaranteed, when you have a consistent, documented history of receiving it, typically over two years. Lenders average it like other variable income, and overtime that is declining or only occasional may be excluded or counted at a reduced figure.
