The short answer
Form 1099 is the IRS information-return family used to report various types of income to the IRS and to taxpayers. For merchant-account operators, the one that matters is Form 1099-K — filed by every payment settlement entity (acquirer, PayFac) that reports your gross card processing volume and transaction count. Other 1099 forms (1099-NEC, 1099-MISC, 1099-INT) may also apply to your business depending on structure.
The 1099 forms relevant to operators
1099-K (Payment Card + Third-Party Network Transactions)
The core merchant 1099. Filed by your acquirer or PayFac. Reports gross card volume (before fees, refunds, or chargebacks) and transaction count per calendar year. Copies go to IRS + to you. Each brand with its own merchant account receives its own 1099-K; a parent merchant account receives one 1099-K covering all sub-brands. See our 1099-K entry for full thresholds and filing details.
1099-NEC (Non-Employee Compensation)
Filed by you, for payments $600+ made to independent contractors, freelancers, service providers. Due January 31.
1099-MISC (Miscellaneous Income)
Replaced by 1099-NEC for most contractor payments in 2020. Still used for rent, royalties, prizes, medical payments, attorney fees $600+.
1099-INT (Interest Income)
Filed by banks. Relevant if your business checking earns interest or your reserve account earns nominal interest.
1099-DIV (Dividends)
Relevant if you receive dividends from holdings (e.g., corporate investments).
What shows up on your 1099-K specifically
- Box 1a: Gross amount of payment card / third party network transactions. Your total card volume for the year, pre-fees + pre-refunds + pre-chargebacks. This is a gross number; your tax return needs to reconcile it down to actual net income.
- Box 1b: Card not present transactions. The CNP slice of Box 1a.
- Box 3: Number of payment transactions. Transaction count.
- Boxes 5a-5l: Monthly gross amounts. Jan-Dec breakdown.
- Box 2: Merchant category code. Your assigned MCC.
Multi-state 1099 reporting
Several states (Massachusetts, Vermont, Illinois, Virginia, Maryland, Washington DC, New Jersey) have lower 1099-K thresholds than federal. If you have customers or a business nexus in those states, you may receive a state-level 1099-K even if your federal gross doesn't trigger reporting. Reconciling state-level information returns with federal is a common accounting headache for growing operators.
What the IRS does with your 1099-K
They automate-match it against your tax return. If you reported $500,000 in gross revenue but your 1099-K shows $650,000, you'll get a CP2000 notice asking to explain the difference. Common legitimate differences:
- Refunds, returns, chargebacks not on the gross 1099-K.
- Revenue recognized in a different tax year than the card charge (annual subscription sold December, recognized ratably over 12 months).
- Sales tax collected (if reported separately).
- Split between business vs. personal activity (don't use your business account for personal).
Why multi-brand operators care
Each merchant account produces its own 1099-K. If you run 4 brands on 4 processors, you receive 4 separate 1099-Ks that must each reconcile. Under a parent merchant account via multiflow, you receive one consolidated 1099-K covering the parent entity, with sub-brand breakdowns available in your portal. Simpler filings, fewer reconciliation fires.
How multiflow exposes 1099 data
Your operator portal maintains a 1099 preview all year: running gross card volume, transaction count, sub-brand split. When the acquirer issues the final 1099-K in January, it matches your portal numbers. Copies archived in your portal for 7 years.
