Year-End Business Document Checklist: W-9s, 1099s, and W-2s Before January 31

Every business that pays employees or contractors has a hard deadline: January 31 is when W-2s go out to employees and 1099-NECs go out to contractors, and both start with a W-9 you should already have on file. If you're missing paperwork or haven't touched your accounting software since last year's filing, here's exactly what to check, fill in, and send before the deadline, and where the rules actually changed for 2026.

What Has to Go Out by January 31

Three documents drive this checklist, and each has a different trigger:

• Form W-9 should be on file for every contractor, freelancer, or vendor you paid during the year, collected before you pay them, not after you're scrambling to file.
• Form W-2 goes to every employee you withheld income, Social Security, or Medicare tax from, or paid at least $600 in wages to, even if that employee only worked for you for a few weeks.
• Form 1099-NEC goes to non-employees you paid for services. For payments made in 2025, the reporting threshold is $600. For payments made starting January 1, 2026, the One Big Beautiful Bill Act raises that threshold to $2,000, so contractors paid between $600 and $2,000 during 2026 won't need a 1099-NEC when you file in early 2027. It's easy to apply the old $600 rule out of habit, so check which calendar year of payments you're actually reporting before you decide who gets a form.

Here's how the three documents line up against each other:

Both W-2s and 1099-NECs are also due to the Social Security Administration or IRS by January 31, the same date as the recipient copy. There's no separate paper-versus-e-file grace period for either one the way there is for some other information returns, so build your checklist backward from that single date rather than assuming you have until mid-February.

One more wrinkle: if you're filing 10 or more information returns total across all types (W-2s, 1099-NECs, and any other 1099s combined), the IRS requires you to e-file rather than mail paper copies. Most small businesses with even a handful of employees and contractors cross that threshold without realizing it, so check your total count before you assume you can print and mail everything from your desk. Some states also require a separate copy of the 1099-NEC filed directly with the state's department of revenue, on top of the federal filing, so confirm your state's rule if you have contractors working across state lines.

Step 1: Chase Down Missing or Incomplete W-9s

Pull your vendor and contractor payment report for the year and flag anyone without a W-9 on file, or with an incomplete one: a missing EIN or Social Security number, an unclear entity type box, or a form that was never actually signed. This step alone is where most year-end filings go sideways, because a business owner realizes in mid-January that a contractor they paid $4,000 to in March never sent one back.

Email the form to them, or better, upload a blank W-9 once and use PDF Editify's fill tool to send a fillable version they can complete from a phone or laptop, then sign electronically without printing anything. Chasing this down in October or November, not the third week of January, is what actually protects the deadline. Our W-9 guide walks through the form field by field if you're filling one in yourself as a sole proprietor collecting payments from a client or platform.

If a contractor won't return a signed W-9 after a couple of reminders, you're required to begin backup withholding at a flat 24% on future payments until you get one. That single rule is usually enough to get a late W-9 back within a week.

Step 2: Fill In and Send W-2s to Employees

For each employee, confirm year-end totals for wages, federal and state withholding, and any benefits that affect Box 12 or 14 (retirement contributions, HSA contributions, dependent care benefits) before you touch the form itself. Then:

1. Upload a blank Form W-2, or your payroll provider's exported copy, to PDF Editify.
2. Fill in the employer identification section (EIN, name, address) once, since it's identical across every employee's copy.
3. Fill in each employee's wage and withholding boxes individually, double-checking that Box 1 (wages) and Box 5 (Medicare wages) aren't accidentally identical when pre-tax benefits should separate them.
4. Generate Copy B and Copy C for the employee, and keep Copy A, along with the W-3 transmittal, for your Social Security Administration filing.
5. Send the employee copy for review and, if your process requires it, an acknowledgment signature confirming they received it.

Our full Form W-2 walkthrough covers each box in detail, including the common mismatch between W-2 totals and quarterly payroll filings (Form 941) that trips up first-time filers when the two don't reconcile at year-end.

Step 3: Fill In and Send 1099-NECs to Contractors

With your W-9s in hand, filling in 1099-NECs is mostly a matter of matching names, taxpayer ID numbers, and payment totals correctly rather than complex tax calculation:

1. Confirm the contractor's legal name and TIN match exactly what's on their W-9. A mismatch, a business name on the 1099 but a personal SSN on the W-9, for example, is the single most common reason a 1099 gets rejected or triggers an IRS notice months later.
2. Fill in Box 1 with total nonemployee compensation for the year, using the correct threshold ($600 for 2025 payments, $2,000 for 2026 payments) to decide who needs a form at all. Don't forget to add up payments across multiple invoices; the threshold applies to the calendar-year total, not any single payment.
3. Leave Box 4 (federal income tax withheld) blank unless you were required to backup withhold on that contractor.
4. Send the contractor their copy and keep your own copy, along with proof of delivery, for IRS filing.

See our 1099-NEC guide for a box-by-box breakdown, including how it differs from 1099-MISC for rent, royalty, or legal settlement payments that use a different form entirely.

Keeping Records for the SSA and IRS Copies

Beyond the copies you send to employees and contractors, you're also responsible for filing with the Social Security Administration (W-2s, via the W-3 transmittal) and the IRS (1099-NECs, filed directly or through the IRIS system). Keep a dated, organized folder, physical or in cloud storage, with every W-9 collected, every W-2 and 1099 sent, and a record of when and how each was delivered.

Missing the deadline isn't free: penalties for late or incorrect information returns start around $60 per form if you correct within 30 days, rise to $130 per form after that, and reach $340 per form if you file after August 1 or not at all. Intentional disregard carries its own $680-per-form penalty with no cap. All of that is per form, not per business, so ten missed 1099s can turn into a real bill fast, which is exactly why the paper trail matters more than most business owners expect until the year they actually need it.

If this is a once-a-year task for your business rather than a monthly one, it rarely makes sense to pay for a full annual PDF or payroll subscription just to fill in a handful of forms. PDF Editify's One Week Plan is a $3 one-time purchase that expires on its own, nothing to cancel and no auto-renewal to catch in March, which covers exactly this kind of short, deadline-driven paperwork sprint without committing you to a recurring charge for a task you only do once a year.
