FHA counts overtime income toward your mortgage qualification if you have a documented two-year history of earning it and your employer confirms it is likely to continue. The lender averages your overtime earnings over the most recent 24 months and adds that monthly average to your base salary to calculate your total qualifying income. For many hourly workers in industries like healthcare, manufacturing, law enforcement, and oil and gas, overtime income can make the difference between approval and denial.
This guide covers the exact FHA rules for overtime income, how the two-year average is calculated, what happens when overtime fluctuates or declines, how bonus and part-time income are handled separately, and what documentation you need. If overtime is a meaningful part of your paycheck, understanding how your lender will treat it is essential before you start house shopping.
Why Does FHA Require a Two-Year Overtime History?
FHA requires a two-year history because overtime income is variable — it is not guaranteed the way base salary is. An employer can reduce or eliminate overtime at any time based on business conditions, seasonal demand, staffing levels, or budget constraints. The two-year lookback period gives the lender enough data to determine whether your overtime earnings are consistent, predictable, and likely to continue.
Without two years of documented overtime, FHA will not allow it to be included in your qualifying income. This means if you just started a new job six months ago that includes regular overtime, that overtime cannot be counted — even if you are earning $1,500 per month in OT right now. The two-year requirement must be met with the same employer or in the same line of work (if you changed employers but remain in the same field).
The two-year history is verified through three documents:
- W-2 forms from the most recent two tax years — these show your total annual earnings including overtime
- Recent pay stubs (typically covering the most recent 30 days) — these show your current base pay and year-to-date overtime earnings
- Verification of Employment (VOE) — a form completed by your employer that breaks out your base pay, overtime, bonus, and commission income separately and indicates whether each is expected to continue
The VOE is the critical piece. If your employer completes the VOE and indicates that overtime is not expected to continue — even if you have two years of history — the lender may not be able to use it. The combination of historical consistency and forward-looking employer confirmation is what FHA requires.
How Is Overtime Income Averaged for FHA?
The standard calculation takes your total overtime earnings from the two most recent full calendar years and divides by 24 months. Here is an example:
| Year | Overtime Earnings |
|---|---|
| 2024 | $14,400 |
| 2025 | $16,800 |
| Total (2 years) | $31,200 |
| Monthly Average | $1,300 / month |
That $1,300 per month is added to your base salary for qualification. If your base pay is $4,500 per month, your total qualifying income becomes $5,800 per month. Using standard FHA debt-to-income ratios, the additional $1,300 in monthly income could increase your maximum purchase price by approximately $30,000 to $45,000 depending on interest rates and other factors.
Some lenders also factor in your year-to-date overtime as a data point. If your current year's overtime pace is significantly above or below the two-year average, the lender may adjust the qualifying figure. For example, if you averaged $1,300 per month over the past two years but your current year-to-date pace is only $800 per month, the underwriter may use the lower figure or ask for an explanation.
How Does Year-to-Date Income Affect the Calculation?
The year-to-date (YTD) overtime figure from your most recent pay stub acts as a real-time check against the two-year average. Lenders compare your YTD pace to the historical average to see whether your overtime is trending up, down, or staying consistent. The three common scenarios:
- YTD pace matches or exceeds the two-year average — The lender uses the two-year average. No issues.
- YTD pace is slightly below the average (less than 20% decline) — The lender typically still uses the two-year average but may note it. Some cautious underwriters will use the lower YTD pace.
- YTD pace is significantly below the average (more than 20% decline) — The lender may reduce the qualifying overtime income to match the current pace, or require a written explanation from the employer about why overtime has decreased and whether it is expected to recover.

Check My FHA Eligibility →What Happens If Your Overtime Income Is Declining?
Declining overtime is one of the most common issues that affects FHA qualification for hourly workers. If your overtime dropped significantly from one year to the next, the lender has to account for the downward trend rather than simply averaging the two years.
HUD Handbook 4000.1 instructs lenders to evaluate whether overtime income has a reasonable expectation of continuance. When the trend is clearly downward, the lender may:
- Use only the lower year's overtime rather than the two-year average
- Exclude overtime entirely if the decline is severe or the employer indicates overtime may not continue
- Request an employer letter explaining the decline and providing a forecast for future overtime availability
For example, if you earned $18,000 in overtime in 2024 but only $9,000 in 2025 (a 50% decline), the lender is unlikely to use the $13,500 average ($1,125/month). Instead, they may cap your qualifying overtime at the 2025 level ($750/month) or exclude it altogether if the employer cannot confirm overtime will continue.
The practical impact is significant. Losing $1,000 per month in qualifying income can reduce your maximum purchase price by roughly $25,000 to $35,000. If overtime is a critical part of your qualification, monitor the trend and have a conversation with your lender early — before you commit to a price range that your declining overtime may not support.
How Does FHA Handle Bonus Income?
Bonus income follows nearly identical rules to overtime income. FHA requires a two-year documented history of receiving bonuses, the bonuses must be likely to continue, and the lender averages the two most recent years to determine a monthly qualifying amount.
The key distinction is that bonuses are often paid annually or semi-annually rather than appearing on every paycheck. This means the lender relies more heavily on your W-2 forms and the employer's VOE to document bonus history, since your regular pay stubs may not show bonus income consistently.
Some additional nuances for bonus income:
- Performance-based bonuses — If your bonus is tied to individual or company performance, the lender evaluates whether performance targets are consistently met. Two years of receiving the bonus is generally sufficient proof.
- Signing bonuses — One-time signing bonuses for a new job are not recurring income and cannot be used for qualification. They may, however, be used as assets for your down payment.
- Guaranteed bonuses — If your employment contract guarantees a specific bonus amount, the lender may be able to use that amount rather than averaging, but this is uncommon outside of certain industries.
- Declining bonuses — Treated the same as declining overtime. The lender may use the lower year or exclude the income if the trend suggests bonuses may not continue at prior levels.
Can You Use Part-Time Income to Qualify for FHA?
Yes, FHA allows part-time job income to be used for qualification if you meet specific criteria. The requirements are similar to overtime and bonus income but with some additional considerations:
- Two-year history — You must have held the part-time job for at least two years. The two years can be with different employers as long as the employment was continuous in the same type of work.
- Likelihood of continuance — The part-time employer must confirm that your employment is expected to continue. Seasonal or temporary part-time work does not qualify.
- No negative impact on primary job — The underwriter verifies that your part-time schedule does not conflict with your primary employment. Working two full-time-equivalent schedules may raise questions about sustainability.
Part-time income is averaged the same way as overtime — total earnings over 24 months divided by 24. If you earned $18,000 from your part-time job over the past two years, that adds $750 per month to your qualifying income.
One common scenario: a nurse who works full-time at a hospital and picks up per-diem shifts at a second facility. If the per-diem work has been consistent for two or more years, the income from those extra shifts can be used to qualify for a larger FHA loan.
What Documentation Do You Need?
To use overtime, bonus, or part-time income on your FHA application, you will need to provide:
- Two years of W-2 forms — These show total earnings and often break out overtime separately. Your W-2 is the primary proof of historical income.
- 30 days of pay stubs — Current pay stubs showing your base rate, overtime rate, hours worked, and year-to-date totals for each income type.
- Verification of Employment (VOE) — Your employer completes this form, providing your hire date, position, base pay, overtime history, bonus history, and whether each income type is expected to continue. This is the single most important document for variable income.
- Two years of federal tax returns (in some cases) — While not always required for W-2 employees, some lenders request tax returns to cross-reference with W-2 income, especially when overtime is a large percentage of total earnings.
- Employer letter (if needed) — If overtime has declined or the VOE raises questions, an additional letter from your employer explaining the situation may be requested.
The cleaner and more consistent your documentation, the smoother the underwriting process. If your overtime fluctuates by season (common in construction, oil and gas, and agriculture), having your employer provide a letter explaining the seasonal pattern — and confirming that overtime is expected to continue at historical levels — can preempt underwriter questions.
How Can You Maximize Your Qualifying Income?
If overtime, bonus, or part-time income is a significant part of your earnings, here are strategies to maximize what your lender can use:
- Maintain consistency — Two years of similar overtime earnings are far more powerful than one great year and one weak year. Even if overtime is available, working it consistently strengthens your two-year average.
- Keep detailed records — Save every pay stub and W-2. If you switch employers within the same industry, document the transition to show continuity of employment.
- Communicate with your employer — Make sure your HR department understands the importance of the VOE form and will accurately report your overtime history and expected continuation.
- Time your application strategically — If possible, apply after two strong calendar years of overtime rather than mid-year when YTD figures may be low due to seasonal patterns.
- Work with a lender early — Have your income analyzed at least 60 to 90 days before you want to make an offer. At Bayou Mortgage, we calculate your qualifying income including all variable sources upfront so you know your real budget before you start house hunting.
- Build your credit score — A higher credit score provides more flexibility on debt-to-income ratios, which can compensate for variable income situations.
