MCA underwriting in 2026 increasingly uses business tax returns as the cross-check on bank deposits and merchant-stated revenue. Where 2018-era MCA approvals never asked for a tax return, the 2026 norm — driven by larger average advance sizes, stricter capital partners, and new state disclosure laws — is that any advance over $75K likely requires the most recent filed business return.
When tax returns are required.
- Advances over $75K at most top-30 funders (some thresholds are $100K).
- All renewals at A-paper funders.
- Any "premium" or low-factor product.
- Businesses claiming significantly higher revenue than tax-return revenue (cross-check trigger).
- Multi-entity merchants (one return per entity).
What "tax return" means.
- C-corp. Form 1120 plus all schedules (Schedule L balance sheet, Schedule M-1 book-to-tax reconciliation).
- S-corp. Form 1120-S plus K-1s for each shareholder over 20%.
- Partnership / LLC. Form 1065 plus K-1s.
- Sole proprietor. Schedule C from the principal's Form 1040 (and the full 1040 if requested).
Always send the full return, not just the first page. Funders need depreciation schedules, balance sheet detail, and pass-through K-1s for accurate underwriting. Sending only the cover page triggers a stipulation.
The bridge memo (highest-leverage add).
If the tax return is from a year with materially different revenue than the current trailing 12 months, write a 1-page bridge memo:
- Tax-return year revenue: $X.
- Trailing 12-month bank deposit revenue: $Y.
- Drivers of the change: new locations, price changes, customer wins, market expansion, post-COVID recovery, seasonality timing.
- Supporting documentation: customer contracts, ramp metrics, location-count growth.
Without the memo, the underwriter assumes the lower number and sizes the advance off it.
Recency of return.
- Returns filed within the last 12 months are "current."
- Returns 12–18 months old are acceptable with a strong bridge memo.
- Returns 18+ months old (e.g. consistent late-filers) raise concern; some funders decline.
- If the merchant has not yet filed for the most recent fiscal year, an extension confirmation plus a draft return prepared by the CPA is usually acceptable.
Filing extension explanation.
If the merchant filed an extension and has not yet filed the prior year's return, prepare:
- Copy of Form 7004 (corporation extension) or Form 4868 (individual extension) showing the extension was filed timely.
- Brief explanation of why (waiting on K-1s from investments, complex transaction, change in CPA).
Lack of an extension explanation reads as "merchant has something to hide."
Owner-draw / distribution treatment.
S-corp and LLC merchants often show low pass-through income because owners take distributions rather than wages. Funders sometimes misread this as low business profitability. Bridge memo should:
- Identify total owner compensation including distributions.
- Show that adjusted EBITDA (adding back owner draws above market-rate salary) is healthier than the pass-through income suggests.
Depreciation add-back.
Section 179 expensing and bonus depreciation can make a profitable business look unprofitable on the tax return. Bridge memo should:
- Add back depreciation to compute true cash earnings.
- Identify any one-time accelerated deduction (large equipment purchase, building improvement).
- Show normalized EBITDA.
Revenue-recognition timing differences.
Cash-basis tax returns vs. accrual books cause apparent mismatches. Bridge memo should:
- State which basis the return uses.
- Bridge to bank deposit accrual where relevant.
- Reconcile AR growth or shrinkage between fiscal year-end and current.
Personal tax return — when required.
Some funders (especially for guarantor-heavy underwriting) request the principal's personal 1040. Common triggers:
- Advance over $150K with personal guarantee.
- Sole proprietor or pass-through entity where business income is the principal's income.
- Multi-entity owner with material outside income.
If requested, send the full 1040 with all schedules. Redacting SSN is acceptable; do not redact income or dependent information.
Multi-entity handling.
Merchants with multiple related entities (real estate LLC, operating LLC, holding company) should:
- Send a return for each entity, even if requested for just one.
- Provide an org chart showing entity relationships.
- Identify which entity is the actual MCA borrower.
- Disclose any intercompany loans or transfers visible on bank statements.
State and local returns.
Most funders only request federal. Some require state returns for states with material sales tax filings (CA, NY, TX). If requested:
- Send the most recent state return for the principal state of operation.
- Send sales tax filings for the last 4 quarters if revenue-heavy in a sales-tax state.
Common pitfalls.
- Sending only the first page of the return.
- Sending the prior year's return when the most recent year is filed (always send the most recent).
- Failing to bridge tax-return revenue to current bank deposits.
- Failing to disclose that the return is on extension.
- Submitting a draft return that does not match what was filed (or will be filed).
- Redacting income figures or schedule detail.
Format quality.
- PDF from the CPA's preparation software (e.g. TurboTax Business, Lacerte, Drake) directly, not scans of paper copies.
- All schedules in single file or named files.
- Cover page showing the merchant's CPA preparer signature.
Takeaway. Tax returns are the most-stipulated document after bank statements on MCA applications over $75K. A complete return with a clear bridge memo to current bank deposits routinely earns 25–50% larger advances and faster decisions than a partial or unexplained return.
