Refinance With Variable Income — The Quick Read: Bonus, commission and overtime pay can count toward a refinance, but only with a documented history and a stable or rising trend. A full-documentation loan averages the income and drops whatever it can’t support. Streamline products on existing FHA and VA loans may skip income calculation entirely, so the loan type often matters more than the paycheck. Every figure here is subject to lender guidelines and full file review, and nothing is a commitment to lend.
Key Takeaways
- Variable pay counts only when the loan type requires income to be calculated and the lender can document it.
- Lenders average the income. They don’t use your best year.
- A falling trend can cut the figure or remove it.
- You may still qualify on base pay alone.
- Streamlines on existing FHA and VA loans can skip the income review, with exceptions.
What Counts as Variable Income?
Variable income is pay on top of a steady base. The usual types are bonus, commission and overtime. Tips, seasonal pay and hourly work with changing hours fall in the same bucket.
Lenders split these out from base pay and treat each one separately. A salaried borrower with a $0 bonus year and a salaried borrower with a big bonus year look the same on base pay. The difference only shows up when the extra income is needed to make the ratios work.
How a Full-Documentation Refinance Treats It
The conventional rules are the clearest place to start. Under the Fannie Mae Selling Guide B3-3.3-02, the lender needs a completed employer verification form, or the latest paystub plus two years of W-2s. A verbal verification of employment follows.
A two-year history is the recommended standard. Income received for at least 12 months can still be used if other strong factors offset the shorter record.
Across the wholesale programs I place files with, the same pattern shows up. The files that stall are rarely the ones with low variable income. They are the ones where the paystub, the W-2s and the employer verification tell three slightly different stories.
How the Underwriting Works, Step by Step
1. Pick the refinance path. Conventional rate-and-term, FHA Streamline and VA streamline refinances each handle income differently. Income is calculated only if the path calls for it.
2. Submit the application. Income goes on the standard loan application. Base pay and each variable type are listed separately.
3. Provide documents. Expect the latest paystub with year-to-date earnings, two years of W-2s, and an employer verification.
4. The lender sets pay frequency. Each income type gets its own frequency, so a quarterly bonus isn’t blended with weekly overtime.
5. The trend test. The lender compares year-to-date monthly income with prior years. Stable or rising income is averaged across at least 12 months. Falling income is used only if it has stabilized, and then at the lower level. Otherwise it is excluded.
6. Qualify. The averaged monthly figure goes into the debt-to-income ratio. Anything the lender can’t support is dropped, and you may qualify on base pay alone.
7. Appraisal and review. Conventional files follow the automated underwriting finding. Some streamline loans need no appraisal at all.
What decides the outcome: length of history, trend direction, whether the pay shows in the employer’s records, the refinance type, and your overall debt-to-income after the new payment.
A Quick Worked Example
Picture a borrower whose bonus was strong two years ago, lower last year, and lower again year-to-date. The trend is falling. The lender can’t average the three periods and call it done. It must confirm the pay has stabilized, then use the lower level. If it can’t confirm that, the bonus comes out.
Now flip it. Overtime was modest two years ago, higher last year, and higher again this year. That is a rising trend, so the lender averages it. The borrower gets credit for a figure below their current run rate, which is normal.
The Structures: Which Refinance Type Fits?
| Refinance type | Income calculated? | Key point |
|---|---|---|
| Conventional rate-and-term | Yes | Full documentation; up to 95% LTV on a one-unit principal residence |
| FHA Streamline, non-credit-qualifying | Generally no | Existing FHA loan, no appraisal, net tangible benefit |
| FHA Streamline, credit-qualifying | Yes | Income and credit are documented |
| VA IRRRL | Generally no | Existing VA loan, no VA appraisal, net tangible benefit |
The conventional rate-and-term refinance pays off the existing first mortgage, the closing costs and any purchase-money second lien, with only incidental cash back. Mortgage insurance applies above 80% LTV. It can be cancelled at the borrower’s request at 80% of the original value, and the servicer must end it automatically at 78%, as the Homeowners Protection Act requires. First-time-buyer programs can go to 97% where the existing loan is agency-owned and the program allows it.
The HUD streamline page lays out the FHA side: the existing mortgage must already be FHA-insured and current, and the refinance has to produce a net tangible benefit. Cash back above $500 isn’t allowed. “Streamline” describes the documentation, not the cost, and closing costs can’t be rolled into the new loan amount.
The VA IRRRL carries a 0.5% funding fee unless the borrower is exempt, with no VA appraisal and a seasoning requirement of the later of 210 days and 6 payments.
Above the conforming limit, the jumbo lanes take over. Those files start at a 660 decision score, can reach 90% leverage, and cap the ratio at 50% on the fixed lanes. Variable income gets the same trend scrutiny there. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.

Where the General Rule Breaks
Income that dropped. Fannie Mae excludes decreasing income unless it has stabilized. Then it uses the lower stabilized level. A borrower who relied on last year’s bonus can lose most of it.
Fannie Mae’s current text says the lender need not verify continuance unless it has reason to doubt it. The two aren’t identical.
Hourly workers with changing hours. Fannie Mae treats these as variable base income, with a 12-month minimum history, under B3-3.3-01.
A lender doesn’t have to verify income it isn’t relying on.
FHA streamline, credit-qualifying version. Some lenders only offer this version. Then variable income can be examined after all.
VA IRRRL with a higher payment. If the monthly payment rises 20% or more, the lender must confirm the veteran qualifies for the new payment. The same applies if the existing loan is more than 30 days past due, per VA Circular 26-20-25. Variable income can matter again.
Tips. Unreported tips can be documented with traditional personal-income documentation and IRS Form 4137. Tax treatment can depend on your situation; borrowers should speak with a qualified tax professional before relying on any deduction or credit.
Common Misconceptions
- “Bonus and overtime never count.” They count with documented history. The CFPB’s ability-to-repay guide says a lender can consider seasonal or bonus income.
- “You need exactly two years.” Two years is the recommended history, not the only path.
- “Lenders use my best year.” They average. A falling trend can cut the figure.
- “A refinance never rechecks income.” Streamlines can skip it. Conventional refinances don’t.
- “I can just state my income.” Lenders generally can’t rely on what a borrower says. They need third-party records like W-2s or payroll statements.
- “Streamline means no cost.” It doesn’t. Costs still exist and are paid at closing or built into the loan. A “no-cost” refinance just moves those costs into the balance or the rate.
What the Decision Looks Like in Practice
Start with the loan you already have. An FHA or VA borrower with a current loan may have a path that doesn’t calculate income at all. A conventional borrower needs the averaging to work.
Next, look at timing. A refinance applied for right after a bonus drop, a job change or a cut in overtime is more at risk, because the year-to-date number gets compared with prior years. If a bonus pays out soon and will lift the trend, waiting can help. If pay is falling, waiting usually doesn’t.
Then run the break-even. Compare the cost of the new loan with the change in payment and how long you plan to stay. That’s the real test, and it doesn’t depend on income type. A related read on this is refinancing with a lower credit score, since score and income problems often arrive together.
Some practical steps before applying:
- Pull two years of W-2s and the latest paystub with year-to-date totals.
- Ask your employer for a letter or verification form that lists bonus and commission separately.
- Check that the pay on your paystubs matches the pay on your W-2s.
- Know your base-pay-only ratio. If the loan works without the variable income, the file gets simpler.
- Don’t take new debt before closing.
Key Terms Defined

Net tangible benefit: A measurable gain to the borrower that an FHA or VA streamline must produce.
Limited cash-out refinance: A refinance that pays off the existing loan and costs, with only incidental cash back.
Debt-to-income ratio: Your monthly debts divided by your monthly income, including the new payment.
Frequently Asked Questions
Can I refinance with one year of bonus or commission history?
It is sometimes possible, but it depends on the lender’s guidelines and a full review of your file. Many lenders prefer a longer track record for variable income, so a single year may be considered only when other parts of the file are strong.
What if my overtime has dropped this year?
The lender compares year-to-date income with prior years. If it is falling, the income is used only at its stabilized level, or excluded. You may still qualify on base pay alone.
Does an FHA Streamline look at my bonus income?
The non-credit-qualifying version generally doesn’t calculate income. The credit-qualifying version does. Some lenders offer only the credit-qualifying version, so ask which one applies before you apply.
Does a VA IRRRL ever check income?
Yes, in some situations. If the payment rises 20% or more, or the existing loan is more than 30 days past due, the lender has to look at whether the veteran qualifies. A standard IRRRL with a lower or similar payment generally doesn’t.
Can I just tell the lender what I earn?
No. Lenders generally can’t rely on a borrower’s own statements. They need paystubs, W-2s or employer verification.
