What This Means for You, Business Owner: 1099s don’t start in January — January is when the quality (or gaps) of your vendor data finally show up.
One of the biggest misconceptions around 1099s is this:
“Isn’t this just something my bookkeeper handles?”
Not exactly.
1099s are not a bookkeeping task — they’re a data cleanup and verification process that depends heavily on what was done (or not done) throughout the year.
This post is part of our December–February 3‑month series, where we’re walking through what actually happens between year‑end bookkeeping and tax filings.
Here’s what 1099 prep really requires:
- Accurate vendor names and legal entities
- Correct tax classifications (individual vs entity)
- Complete and valid W‑9s
- Proper coding of payments throughout the year
- Excluding non‑reportable payments (cards, platforms, reimbursements, etc.)
If any of that information is missing or wrong, January becomes a cleanup exercise — not a simple filing step.
Common issues that surface in January:
- Vendors never provided a W‑9
- Payments were coded incorrectly during the year
- Business vs personal vendors were mixed
- Entity types don’t match IRS records
- “Just file it” pressure creates errors
Bookkeepers can organize the data. But business owners are responsible for:
- Requesting W‑9s
- Following up when information isn’t provided
- Confirming vendor details are accurate
Requesting W‑9s throughout the year — at the time you begin paying a service provider — matters.
Why?
- Vendors are more responsive early in the relationship
- Waiting until January creates friction and delays
- Vendors may be unresponsive, unavailable, or no longer working with you
- Your bookkeeper can code payments correctly from the start
- It reduces year‑end cleanup and correction work
Treat W‑9 collection as part of onboarding a vendor, not a year‑end scramble.
If that work doesn’t happen, 1099s get delayed, corrected later, or generate IRS notices.
Key takeaway:
1099s are only as clean as the vendor data behind them.
Your action item:
Review your vendor list now. Confirm W‑9s are on file, vendor names and entities are correct, and questionable vendors are flagged before forms are issued.
To make this easier, download the 1099 Decision Tree (coming soon). It guides you on which vendors should receive a 1099, what information to provide, and when exceptions apply—so you never guess under January pressure.
If you need guidance, the Year‑End Financial Checklist includes 1099‑related prompts to help you identify gaps early.
No bookkeeper yet? 1099 errors often trace back to inconsistent data and unclear processes. This series is designed to help you understand where cleanup work really comes from — and how to prevent it.
