Can Overtime, Bonuses, and Commission Income Help You Qualify for a Mortgage?

A lot of borrowers assume that their full income — including overtime, bonuses, and commissions — will automatically count toward their mortgage qualification. Some are surprised to find that it does not, or that it counts only partially.

The rules around variable income are specific, and they exist for a reason: lenders need to be confident that the income used to qualify you will continue after closing. Here is exactly how overtime, bonus, and commission income is treated under current guidelines, and what you can do to make sure yours counts.

Why Variable Income Is Treated Differently

Base salary is predictable. Your employer has committed to paying you a specific amount per pay period, and barring a job change or termination, that income will continue.

Overtime, bonuses, and commissions are different. They depend on business conditions, employer decisions, individual performance, and factors outside your control. An employer can reduce overtime hours, eliminate a bonus program, or restructure a commission plan. Lenders account for this uncertainty by requiring a documented history of the income and evidence that it is likely to continue.

The core principle across Fannie Mae, Freddie Mac, FHA, and VA guidelines is the same: variable income must have a history of receipt and a reasonable expectation of continuance to be counted in qualifying income.

Overtime Income

Fannie Mae and Freddie Mac (conventional loans):

Overtime income may be used in qualifying if the borrower has received it for at least two years and the employer confirms it is likely to continue. The income is calculated as an average of the overtime received over the most recent two-year period, documented through W-2s and recent pay stubs.

If the overtime income has been received for less than two years, it may still be considered if the lender can document that the income is likely to continue and there are positive factors that compensate for the shorter history. However, income received for less than 12 months is generally not considered stable enough to use.

A decline in overtime income from year to year requires explanation. If your overtime was significantly higher two years ago than it is now, the lender will use the lower current amount or average the decline — they will not use the higher historical figure if the trend is downward.

FHA loans:

FHA guidelines (HUD Handbook 4000.1) require a two-year history of overtime income to use it in qualifying. The income is averaged over the two-year period. If overtime has been received for less than two years, it may be considered if the lender documents the likelihood of continuance, but FHA underwriters apply this exception conservatively.

The practical implication: If you have been working overtime consistently for two or more years and your employer confirms it is likely to continue, your overtime income will likely count. If you recently started working overtime, or if your overtime has been inconsistent, it may not count — or may count only partially.

Bonus Income

Fannie Mae and Freddie Mac:

Bonus income follows the same general framework as overtime: a two-year history is required, and the income is averaged over that period. The lender will use your W-2s and recent pay stubs to document the history.

One important nuance: if you received a large one-time bonus that is not expected to recur, it generally cannot be used in qualifying income. The bonus must be a regular part of your compensation — annual performance bonuses, for example — not a one-time event.

If your bonus income has increased significantly in the most recent year, the lender will typically average the two-year history rather than using the higher current-year figure. If it has declined, the lender will use the lower amount or the average, depending on the circumstances.

FHA loans:

FHA requires a two-year history for bonus income as well. The same averaging methodology applies. Sporadic or one-time bonuses are not counted.

The practical implication: Regular annual bonuses with a two-year history will typically count. Irregular, one-time, or recently started bonuses may not. Document your bonus history with W-2s and, if possible, a letter from your employer confirming that the bonus program is ongoing.

Commission Income

Commission income receives the most scrutiny of the three categories, because it is the most variable and the most dependent on individual performance.

Fannie Mae and Freddie Mac:

Commission income requires a two-year history, documented through federal tax returns (not just W-2s). The reason tax returns are required is that commission earners often have unreimbursed business expenses that reduce their effective income. The lender will use your Schedule A (if you itemize) to identify unreimbursed employee expenses and subtract them from your gross commission income.

If you earn more than 25% of your total income from commissions, Fannie Mae treats you as a commission-based borrower and requires two years of tax returns to document the income.

The income is calculated as an average of the two-year commission income after subtracting unreimbursed business expenses. If your commission income has declined from year one to year two, the lender will use the lower year-two figure or the average — not the higher historical amount.

FHA loans:

FHA also requires a two-year history for commission income and uses tax returns to document it. Unreimbursed business expenses are subtracted from gross commission income. The same declining-income rules apply.

The practical implication: Commission income with a consistent two-year history and no significant unreimbursed expenses will typically count in full. Commission income that has declined, is less than two years old, or is offset by large unreimbursed expenses may count for less than you expect.

What "Likelihood of Continuance" Means

Across all three income types, lenders must document that the income is likely to continue for at least three years after closing. This is typically satisfied by:

• A verbal or written verification of employment confirming the income type is ongoing
• The nature of the employment (a salaried position with a history of overtime is more stable than a contract position)
• The absence of any indication that the income will stop (pending layoffs, employer financial distress, etc.)

If your employer is in a declining industry, has announced layoffs, or has indicated that overtime or bonus programs are being reduced, that affects the likelihood-of-continuance analysis.

What You Can Do Before Applying

If variable income is important to your qualification, here are the steps that matter most:

Build the two-year history. If you have been earning overtime, bonuses, or commissions for less than two years, the most effective thing you can do is wait until you have the required history. This is not always practical, but it is the cleanest path to having the income counted in full.

Keep your tax returns clean. If you earn commission income, large unreimbursed business expenses on your Schedule A reduce your qualifying income. If you have flexibility in how you structure your expenses, discuss this with a tax professional before applying for a mortgage.

Document everything. W-2s, pay stubs showing year-to-date earnings, and tax returns are the foundation of income documentation. Make sure you have two years of each before you apply.

Avoid income declines in the year before you apply. A declining income trend — even if your current income is strong — will cause the lender to use the lower figure or the average. If you have control over your commission structure or overtime hours, maintaining or growing your income in the year before application strengthens your file.

Talk to a lender before you assume. The rules are specific, and the application to your individual situation depends on your income history, your employer, and the loan program you are using. A pre-application conversation with a lender can tell you exactly how your income will be treated before you are in escrow.

The Bottom Line

Overtime, bonus, and commission income can absolutely help you qualify for a mortgage — but only if it meets the history, documentation, and continuance requirements of the loan program you are using. The two-year history requirement is the most common stumbling block, followed by declining income trends and unreimbursed business expenses for commission earners.

If you are not sure how your variable income will be treated, the best first step is a conversation with a lender who can review your actual pay stubs and tax returns and give you a clear answer before you start shopping for homes.
