Contractor payment records should identify the supplier, work, invoice and payments made during the relevant period. Your tax preparer determines any information-return obligations and worker-classification questions. This guide helps organize records; it does not establish a filing threshold, deadline or universal form requirement.

Make the records make sense.
Keep supplier identity and payments connected
A vendor name in the bank feed may differ from the legal supplier name. Retain invoices and appropriate identity records using a controlled sharing method. Form W-9 provides information used in certain information-reporting workflows; it is not evidence that every worker is correctly classified as a contractor.
Identify the payment route
Payments can pass through checks, bank transfers or platforms. Provide the route and processor information so the preparer can assess applicable reporting without blindly duplicating amounts. Do not decide information-return requirements solely from an expense category.
Check before you close.
List contractor legal identities and appropriate information requested by your preparer.
Collect invoices, service descriptions, dates and payment references.
Identify payment methods, platforms, refunds and amounts still unpaid.
Ask the preparer to confirm classification, forms, filing scope and current-year rules.
Illustrative example · Fictional data
Follow the business event.
Illustrative issue: a supplier invoice is entered for $1,500 and paid in three $500 installments. A records schedule should connect all three payments to the same bill rather than create three more expenses. The preparer separately determines whether and how payments must be reported.
Questions before you get started.
Does a W-9 prove someone is an independent contractor?
No. Worker classification is a separate factual and legal question for the business and its advisers.
Should I send taxpayer IDs through the website form?
No. The initial enquiry needs only a description. Confirm an appropriate document-sharing process before transmitting sensitive information.
