With the right preparation window, the 1099-MISC filing process is predictable and manageable. The key is running W-9 collection, TIN matching, payment classification, and state mapping as one workflow rather than four sequential tasks.
1. Collect and certify W-9s
Obtain a valid W-9 from every payee before or at the time of first payment. Solicitations should be timestamped and documented to meet the IRS Reasonable Cause standard. Missing or expired W-9s must be resolved before filing season opens, not during it. For attorney gross proceeds and medical payments, obtain TINs even when the payee is a corporation; the corporate exemption does not apply to these boxes.
2. Run TIN matching before December
Verify all payee TINs against IRS records before the filing window. Mismatches flagged in November can be resolved quietly. Mismatches discovered in February or March trigger CP2100 notices, backup withholding obligations, and the B Notice response cycle, all with active IRS deadlines.
3. Confirm payment classification
Verify that each payment is going on the correct form and the correct box. Rent, royalties, prizes, medical payments, and attorney gross proceeds go on 1099-MISC. Contractor fees and attorney legal service fees go on 1099-NEC. Same attorney, different forms, depending on payment type. Misclassification is the most frequently cited 1099 error.
4. Map state filing obligations
Identify which states require direct 1099-MISC filing for your payee population, ideally in November. CFSF participation can change year to year, and withholding frequently triggers direct filing even in participating states. Pennsylvania always requires its own myPATH submission.
5. Deliver recipient copies by February 2
Furnish Copy B to each recipient (electronic or paper) by February 2. If Box 8 or Box 10 amounts are reported, the recipient deadline extends to February 17. Document every delivery for your audit trail.
6. File with the IRS by March 2 (paper) or March 31 (electronic)
Submit electronically via FIRE if filing 10 or more information returns across all form types. Paper Copy A is due March 2. Electronic filing via FIRE is due March 31. Confirm and document every submission. FIRE transitions to IRIS for filing season 2027.
