Almost every painful January 1099 season traces back to the same root cause: the W-9 was never collected when the vendor was onboarded. By the time you're trying to file, you're chasing taxpayer IDs from vendors who've gone quiet — some of whom you no longer even have a good email for.
The fix isn't working harder in January. It's running a short checklist in the fall, while there's still time to chase. Here's the order of operations.
Who actually needs a 1099?
The common case is the 1099-NEC: generally required for each non-employee you paid $600 or more during the year for services, when the vendor isn't taxed as a corporation. Payments made entirely by credit card or third-party network are reported by the processor on a 1099-K, not by you. The point isn't to memorize every edge case — it's to know that "paid $600+ for services, not a corporation" is the population you need a W-9 for.
The prep checklist
- Pull the vendor list and year-to-date payments from QuickBooks (or Xero). You want every active vendor and the total you've paid them this year.
- Filter to the 1099-eligible set: paid $600+, for services, not a corporation, not paid solely by card. This is your "needs a 1099" list.
- Cross-check who has a W-9 / TIN on file. Anyone on the eligible list with no taxpayer ID recorded is a gap — and the whole reason January hurts.
- Collect the missing W-9s now. Send a clean, branded request with the blank IRS Form W-9 attached and a secure way to return it. Doing this in October beats doing it in January by a mile — vendors are responsive and you have time to follow up.
- Validate the TINs. Run the names/TINs through IRS TIN Matching before filing so you catch mismatches early instead of getting a CP2100 notice later.
- Map your accounts to the right boxes. Confirm which expense accounts roll into 1099-NEC vs. 1099-MISC so the amounts land in the correct box.
- File on time. 1099-NEC is generally due to recipients and the IRS by January 31. Calendar it backward from there with buffer for the chase.
The mistakes that turn into penalties
- Collecting W-9s only at filing time — the single biggest cause of the scramble.
- Trusting the QuickBooks "track for 1099" flag alone — plenty of eligible vendors are never flagged.
- No record of who's been asked — so the same vendor gets pestered twice and others get missed.
- Missing emails — you can't chase a vendor you can't reach; surface those early so you can call or mail.
Automate the chase
Steps 1–4 are exactly what a connected QuickBooks workflow should do for you: read every vendor and payment, flag who's paid $600+ with no taxpayer ID on file, and draft the W-9 requests — with you approving every send. On a real connected company, this surfaced 6 of 26 vendors missing a W-9 in seconds. See how the 1099/W-9 automation works, or grab the broader admin automation checklist.
