How to Track Subcontractor Payments So 1099s Aren't a January Scramble

January 31st shouldn't be the first time you think about your 1099s. If it is, you're already behind — and possibly exposed to a bigger problem than a late filing.

Here's how subcontractor tracking should actually work, starting the day you hire someone.

Before the first payment goes out: Every subcontractor, LLC (unless taxed as an S-corp or C-corp), or independent laborer you pay $600 or more to in a year needs a completed Form W-9 on file before you cut the first check, not after. That W-9 tells you their legal name, entity type, and Tax ID — the exact information the IRS needs to match against your 1099-NEC filing.

All year long: In QuickBooks Online, every vendor who should receive a 1099 needs to be flagged as a "1099 contractor" in their vendor profile, with payments coded to accounts that map to Box 1 (Nonemployee Compensation) on the 1099-NEC. Payments made by credit card or through a third-party platform like PayPal don't go on your 1099 at all — the card processor reports those — so your books need to distinguish payment method too, or you'll double-report.

At year-end: Instead of digging through twelve months of transactions in January, you're running a report that already has clean, accurate totals by vendor.

Where this goes wrong: Skip the W-9 up front and you're left chasing a subcontractor for their Tax ID in January, sometimes after they've stopped answering calls, which means backup withholding rules technically kick in. Miscode payments or forget to flag a vendor and you either under-report (an IRS mismatch letter waiting to happen) or over-report someone who was actually paid by card.

There's a bigger risk hiding in this too: if the person you're calling a "subcontractor" is really working like an employee — set hours, your tools, your direct supervision, no other clients — the IRS and your state may see worker misclassification, which carries back taxes, penalties, and interest that dwarf any bookkeeping cleanup.

Getting subcontractor tracking right isn't just a January task — it's a year-round habit. Send us a message if you'd like help getting it set up.
