The Decision Rule
Use 12 months when: Income is growing. Your most recent 12-month 1099 total is higher than your prior year.
Use 24 months when: Income is declining or the prior year was stronger. Averaging two years produces higher qualifying income.
Mbanc calculates both and recommends the higher result. You don’t have to choose in advance — present both years of 1099 forms and let the calculation determine the optimal period.
Side-by-Side Calculations
Scenario A: Growing Income (12 months wins)
Year 2023 1099s: $195,000
Year 2024 1099s: $275,000
12-month: $275,000 × 90% ÷ 12 = $20,625/month
24-month: ($195,000 + $275,000) × 90% ÷ 24 = $17,625/month
12 months wins by $3,000/month. At 50% DTI: $1,500/month more PITIA = approximately $200,000 more qualifying loan amount.
Scenario B: Declining Income (24 months wins)
Year 2023 1099s: $285,000
Year 2024 1099s: $195,000
12-month: $195,000 × 90% ÷ 12 = $14,625/month
24-month: ($285,000 + $195,000) × 90% ÷ 24 = $18,000/month
24 months wins by $3,375/month. At 50% DTI: approximately $225,000 more in qualifying loan amount.
Scenario C: Roughly Equal Income
Year 2023: $245,000. Year 2024: $258,000.
12-month: $258,000 × 90% ÷ 12 = $19,350/month
24-month: ($245,000 + $258,000) × 90% ÷ 24 = $18,863/month
12 months wins slightly and is simpler. Use 12 months when income is roughly equal.
The Strategic Timing Question
Your qualifying income is determined by what your 1099 forms show for the period ending at the date of application — not a fixed calendar year.
A contractor whose 1099 income has been growing who applies in Q3 2026 has options:
– 12 months: October 2024 – September 2026 (most recent 12 calendar months of 1099s)
– 24 months: October 2023 – September 2026
If a major new client engagement began in January 2026, waiting until January 2026 to apply gives 12 months of 1099 income that includes that client’s full year. This timing decision can meaningfully change qualifying income for contractors in growth phases.
The loan officer can model the impact of application timing on qualifying income.
When Only 12 Months Is Available
If you became an independent contractor within the last 12-23 months, only 12-month qualifying is possible. The 24-month option requires 2 full calendar years of 1099 documentation.
In this situation: 12-month qualification uses the available period. If 12 months is insufficient for the target loan amount, the options are: wait until 24 months of history is available, or evaluate whether the target loan amount can be reached with 12-month qualifying income.
Declining Income: The Underwriting Question
Using 24-month averaging when current-year income is significantly lower than the prior year produces higher qualifying income — but the underwriter will note the declining trend. A 30-40% income decline from year 1 to year 2 triggers a question: what caused it? Is it resolved? What does the current pipeline look like?
Prepare a brief explanation: “One major contract ended in Q3 2024. I have signed contracts for 2026 with [Clients X and Y] representing $[amount] in annual fees.” A current signed contract or letter of engagement from a client demonstrates that income is recovering — this context helps the underwriter understand the decline as situational rather than structural.
Frequently Asked Questions
Does Mbanc calculate both periods automatically?
Yes. Present both years of 1099 forms and the loan officer calculates qualifying income under both periods. The higher result is the recommendation.
What if I have 1099s from different types of clients across the two years?
All qualifying 1099-NEC and 1099-MISC from all payers are included regardless of client type. The sum of all forms for the period is the gross qualifying income.
Can I cherry-pick specific months from each year?
No. The calculation uses the full qualifying period (12 consecutive months or 24 consecutive months) — not selected months.

The Application Timing Strategy: Optimizing the Qualifying Period
For contractors in growth phases, application timing significantly affects qualifying income. Since the qualifying period is the 12 or 24 months ending at application, waiting a few months can mean the difference between including or excluding a major new contract.
Example — New client started January 2026:
Application in March 2026: January and February of new engagement counted in 12-month period.
Application in January 2026: Full year of new client’s 1099-NEC included in 12-month period.
If the new client contributes $120,000/year, the application timing difference is $10,000/month in 1099 income → $9,000/month qualifying income difference → approximately $1.2M more in qualifying loan amount.
For contractors who are not in a rush, modeling the qualifying income at different application timings and waiting for the optimal window is a legitimate income maximization strategy.
Two-Year Tax Return Confirmation vs Two-Year 1099 Forms
The 2-year contractor history requirement and the 12 or 24 month 1099 income documentation are separate:
2-year history: Established through tax returns, business license, contracts, or CPA letter. Confirms duration of independent status.
12 or 24 month 1099 forms: The income documentation for qualifying income calculation. These are the current-period forms from the qualifying window.
A contractor who was self-employed for 5 years but only has 12 months of high-income 1099s: the history requirement is satisfied by the 5-year self-employment track record, and the income qualification uses the 12 months of documented 1099s.
The Underwriting View of Declining Income
Using 24-month averaging when current-year income declined by 30–50% will trigger an underwriting question. The underwriter’s perspective: is the decline situational (one client ended, being replaced by new clients) or structural (business deteriorating)?
Strong response to declining income question:
“Client A’s engagement ended in Q3 2024. I have signed contracts for 2026 with [new clients], with expected annual 1099 income of [amount]. My current client roster includes [list] representing [total] in annual fees.”
A signed contract or letter of engagement from a current client is the most persuasive document — it demonstrates that the decline was transitional, not permanent.
Weak response: “My income dropped because business was slow.” No forward-looking documentation.
Prepare the explanation before the underwriter asks. Proactive documentation of income recovery eliminates the condition from the file.
24 Months of 1099s: Document Gathering
For 24-month qualification, you need every 1099-NEC and 1099-MISC from every client for both calendar years. Organizing before applying:
Current year (2024) 1099s: Available from clients who issued them in January–February 2026 for the 2024 tax year. Clients are required to file by February 1.
Prior year (2023) 1099s: Typically in your tax files from the prior year’s filing. If lost, clients can reissue duplicates, or you can obtain an IRS wage and income transcript showing 1099s on file for that tax year.
Gather both years into a single organized folder: one per client, clearly labeled with the year and client name. Present in order with the most recent year first.

The Income Trend That Concerns Underwriters Most
A sharp single-year decline followed by stabilization is manageable — particularly when the cause is documented (one contract ended, new ones started). What concerns underwriters more:
Pattern A: $320K → $280K → applying now. Gradual decline over 2 years. This suggests structural reduction in contractor demand for the borrower’s services. The 24-month average still applies, but the stability of future income is in question.
Pattern B: $280K → $190K → applying with 12 months at $190K. Both periods show the decline. Neither 12 nor 24 months produces strong income. This borrower should address income recovery before applying rather than forcing qualification at a lower amount.
Pattern C: $210K → $320K → applying now. Growth trajectory. 12 months at $320K is the recommendation. The growth story is straightforward and favorable.
The income trend matters not just for which period produces higher income — it matters for how confidently the underwriter views income stability going forward.
