Contractor Payroll Checklist

Independent contractors aren’t employees – which means payroll works differently. You don’t withhold taxes for them, but you still need proper paperwork, accurate payment records, and year-end filings. This Contractor Payroll Checklist will walk you through every step of paying 1099 workers correctly. You can also download the printable PDF version.

Step 1 – Collect Contractor Paperwork

• Form W-9 (request for Taxpayer Identification Number)
• Signed contractor agreement (scope, payment terms)
• Proof of insurance or licenses (if required for your industry)

Step 2 – Set Up Payment Tracking

• Enter contractor info into your accounting/payroll system
• Record each payment with date, method, and amount
• Note if payments exceed $600 (threshold for 1099 reporting)

Step 3 – Make Payments Correctly

• Pay according to the contract (hourly, flat fee, milestones)
• Use direct deposit, checks, or payment platforms
• Keep receipts and confirmations

Step 4 – File 1099s at Year-End

• Issue 1099-NEC forms to contractors paid $600+
• File 1099s with the IRS by January 31
• File Form 1096 (transmittal) if filing by paper

Step 5 – Maintain Contractor Records

• Retain W-9s, agreements, and payment records for at least 4 years
• Keep copies of issued 1099s and IRS confirmations
• Separate contractor files from employee payroll records

FAQs

Do I withhold taxes for contractors?
No, contractors are responsible for their own tax filings. You only provide Form 1099-NEC if payments exceed $600.

What happens if a contractor doesn’t provide a W-9?
You may be required to withhold backup withholding (24%) on payments until they provide it.

Can I pay contractors through payroll software?
Yes, most systems support 1099 tracking, but you must still collect W-9s and issue 1099s at year-end.
