Instructions for Form 1099-K Checklist: 2019 Tax Year
Form 1099-K reports payment card transactions and third-party network transactions for the
2019 tax year and supports accurate income tax reporting under Internal Revenue Code
Section 6050W. This 2019 Form 1099-K checklist explains reporting obligations, filing thresholds, box-level requirements, and deadlines that apply to payment settlement entities and third-party settlement organizations.
Form 1099-K Filing and Reporting Steps
Step 1: Confirm Filing Threshold and Transaction Count
Before preparing any tax forms, determine whether you are reporting third-party network transactions as a third-party settlement organization. Under the 1099-K reporting threshold rules, a participating payee is reportable only when gross payments exceed $20,000, and the annual transaction volume exceeds 200.
Payment card transactions follow a different standard and do not qualify for the federal de minimis threshold. Credit card companies and payment networks must report all qualifying payment transactions, regardless of gross amount or transaction count, when those transactions meet the definition of reportable payment card activity.
Step 2: Verify Merchant Category Code Assignment
Each merchant account must have a correctly assigned merchant category code for payment card transactions reported during the tax year. Box 2 requires the four-digit merchant category code used by the payment card industry to classify the payee’s business activity.
Third-party settlement organizations that do not rely on an industry classification system should leave Box 2 blank. Accurate merchant category code documentation supports reconciliation, audit readiness, and proper classification of gross income reported through IRS Form 1099-K.
Step 3: Report Gross Transaction Amount on Line 1a
Report the gross amount of total reportable payment transactions in Box 1a for the calendar year using the 2019 format. Gross transaction amounts must reflect total processed payments without subtracting refunds, processing fees, or chargebacks.
This figure represents gross payments processed through payment settlement networks, including digital payments and credit card activity. You should ensure internal totals reconcile to monthly records to support income tax and tax return preparation.
Step 4: Enter Monthly Breakdown on Lines 5a Through 5l
Boxes 5a through 5l require a monthly breakdown of gross payments processed during each calendar month. Each box must reflect the gross amount of total reportable payment transactions for that specific month.
Monthly reporting supports IRS matching and helps small businesses reconcile income across payment processors, online marketplaces, and virtual marketplace platforms. Accurate monthly entries also assist when preparing Schedule C or Schedule E reporting.
Step 5: Include Card-Not-Present Transactions
Box 1b captures card-not-present transactions, including keyed credit card numbers or remote payment processing activity. This box reports a subset of gross payments already included in
Box 1a rather than an additional reporting category.
Online stores, payment apps, and peer-to-peer payment systems frequently generate card-not-present activity. Proper reporting ensures transparency for electronic filing and reduces the risk of mismatches during Internal Revenue Service reviews.
Step 6: Assign Correct Federal Income Tax Withholding Status
Determine whether backup withholding applies based on the payee’s Taxpayer Identification
Number certification. When required, report federal income tax withheld in Box 4 using the 24 percent backup withholding rate applicable for 2019.
Backup withholding applies when a payee fails to provide a valid Taxpayer Identification Number or receives an IRS notice. This amount should never appear in state boxes and must align with withholding records maintained throughout the tax year.
Step 7: Document State-Specific Reporting Adjustments
Some states applied lower reporting thresholds or independent filing requirements during the
2019 tax year. Even when federal filing is not required, state-level tax reporting obligations may still apply to payment transactions.
You should verify whether your state accepts combined federal and state filing or requires separate submission. Maintaining awareness of state rules supports compliance requirements and avoids penalties tied to incomplete reporting.
Step 8: Prepare Form 1099-K Copy B for Merchant
Furnish Copy B of Form 1099-K to the merchant or participating payee by January 31, 2020.
Copy B must reflect the same gross payments, backup withholding, and reporting details submitted to the IRS.
Merchants rely on Copy B to prepare tax returns and determine taxable income from payment settlement networks. Retaining copies supports customer service inquiries and documentation requests from tax professionals.
Step 9: Complete Form 1096 Annual Summary Transmittal
Form 1096 serves as the annual summary transmittal for paper-filed Forms 1099-K. This form aggregates totals and accompanies Copy A submissions sent to the Internal Revenue Service.
You should not use Form 1096 for electronic filing. Accurate totals on Form 1096 ensure consistency between individual tax forms and the overall submission package.
Step 10: Report De Minimis Transactions and Exceptions
For third-party network transactions reported by third-party settlement organizations, apply the federal de minimis rule strictly. A participating payee becomes reportable only when both the gross amount and transaction count thresholds are exceeded.
Payment card transactions remain fully reportable regardless of dollar value or frequency.
Understanding this distinction prevents underreporting and ensures proper classification of third-party network transactions and 1099-K activity.
Step 11: File by Deadline and Correct Processing Errors
File Form 1099-K with the IRS by February 28, 2020, for paper submissions or March 31, 2020, for electronic filing. These deadlines apply regardless of whether payment transactions involve digital payments or traditional credit card processing.
If errors appear after filing, submit corrected forms following standard correction procedures.
Furnish a corrected Copy B to the payee and retain documentation supporting the revision.
- Full IRS transcript retrieval (Wage & Income + Account)
- Professional tax form review
- Preparation & filing support
- Tax relief options if you owe the IRS
Step 12: Maintain Reconciliation Records and MCC Documentation
Maintain copies of all filed Forms 1099-K, Form 1096 submissions, monthly reconciliation reports, and merchant category code documentation. These records support inquiries related to gross income, payment thresholds, and reporting obligations.
You should also retain W-9 forms, withholding certifications, and account number references.
Strong record retention practices reduce risk during audits and support compliance across federal and state tax reporting frameworks.
2019-Specific Changes and Guidance
For 2019, the $20,000 and 200-transaction threshold continued to apply exclusively to third-party settlement organizations. Payment card transactions processed by payment settlement entities remained fully reportable under Section 6050W.
Monthly reporting in Boxes 5a through 5l remained mandatory, and the backup withholding rate stayed at 24 percent. The January 31 Copy B furnishing deadline also remained unchanged for the 2019 tax year.
State-level variations continued to affect filing requirements, particularly for online marketplaces and payment service providers. Card-not-present transactions required a separate disclosure in
Box 1b without altering gross payment totals.
This checklist functions as a complete reference for preparing, filing, and retaining Form 1099-K records for the 2019 tax year.
