The contractor year-end file: W-9 to 1099 without a December scramble
The year-end form is the last step. The real control is collecting identity, classification evidence, payment detail, and exceptions early enough to fix them.
A contractor year-end process should collect and validate Form W-9 before payment, document the worker-classification decision, track service payments by legal payee and payment method, reconcile the contractor register to the general ledger, apply the current year's Form 1099-NEC instructions, resolve exceptions, and retain filing evidence. Do not hard-code an old reporting threshold into the bookkeeping workflow; the current IRS instructions control.
2026 PAYMENT-YEAR CHECK
$2,000—not the old $600 shortcut.
The IRS lists a $2,000-or-more threshold for reportable nonemployee service payments made in 2026. Prior-to-2026 payments use the earlier $600 threshold. This is not a blanket rule for every vendor or payment channel, and it is not an income-tax exemption for the recipient.
Keep the year, legal payee, payment method and exceptions attached to the decision. Verify later years separately because inflation adjustments begin after 2026.

Jordan Lee · $2,350 YTD
What resolves this?
Securely collect the signed W-9, confirm the legal payee and tax classification, and route any withholding question to the tax reviewer. An invoice address alone does not complete the file.
Name mismatch
Cedar Repair · $780 YTD
What resolves this?
Match the trade name to the legal name on the W-9. Merge aliases in the payment register without deleting the transaction history. Keep evidence of the review.
Channel review
Pixel Market · $3,100 YTD
What resolves this?
Separate card or qualifying third-party network payments from direct payments. Apply current IRS instructions to the payment channel and payee; do not exclude everything paid through an app.
Classify the relationship before choosing the form
A vendor label in accounting software does not decide whether a worker is an employee or independent contractor. Classification depends on the facts and the right to control the work. Document who made the decision, what evidence was considered, and when it will be revisited.
The IRS contractor guidance starts with the classification determination and then directs payers to collect Form W-9. If facts are unclear, route the decision to qualified payroll or tax counsel rather than allowing accounts payable to infer status from an invoice.

Collect W-9 information securely
Request the legal name, business name when applicable, federal tax classification, address, TIN, certifications, signature, and date through a secure process. Restrict access because the form contains sensitive taxpayer information.
Use the W-9 to establish the canonical payee record. Alias names and payment-app labels should map to that record so payments are not split across duplicate vendors and omitted from year-end review.

Maintain a payment register with exclusions visible
Track date, amount, legal payee, service or other payment type, payment method, account, source document, and reporting-review status. Do not delete payments that may be excluded; keep the reason and evidence so the annual total remains reproducible.
Payments can require different treatment based on recipient, service, entity, payment channel, or current instructions. The register flags decisions but does not replace the year's official Form 1099-NEC and information-return guidance.

Run a pre-close exception report
Before the final month, identify missing W-9s, name-TIN issues, duplicate payees, payments near the current reporting threshold, attorney payments, mixed service and reimbursement amounts, and vendors with uncertain classification.
Assign each exception an owner and due date. If backup withholding or another withholding rule may apply, escalate promptly. Do not improvise from a prior-year checklist because filing platforms, thresholds, and instructions can change.

Reconcile filing totals to the books
Tie the contractor register to relevant expense, asset, and payable accounts, then explain differences for excluded payment types, reimbursements, card or third-party network processing, timing, and corrections. Review by payee and in total.
Retain the final payee register, approved decisions, forms furnished, filing confirmations, corrections, and the exact instructions used. Store sensitive forms separately from general close workpapers and expose only the minimum data needed for review.
