How do I handle a contractor who has been paid and refuses to now fill out a W-9 i.e. give their tax ID number to complete their 1099?

Hi there, nu.laceygordon.

I'll provide insights on how contractor's details work in filing 1099 in QuickBooks. I'll ensure you can fill out the tax form and file it smoothly.

Please know that when a contractor has failed or refuses to provide the proper W-9 documentation, a business owner or you as an employer is still allowed to prepare and process a 1099 form. This is to make sure you can efficiently report all income to the contractor. This allows the business to deduct the expenses properly. 

However, filing the 1099 electronically in QuickBooks with the incomplete contractor's information is currently unavailable. You'll need to print and mail the form within QuickBooks and use it to manually file the said tax form directly with the IRS.

Here are the steps to print your 1099s:

1. Go to the Payroll menu at the left panel and choose Contractors.
2. Select Prepare 1099s to create your 1099s.
3. When complete, choose the Print and mail instead option.
4. Follow the on-screen steps to check your alignment and print your forms.

In case you need guidelines on how you can make adjustments to your filed 1099 due to incorrect information, you can read this article: Correct or change 1099s in QuickBooks.

If there's anything else you need or you have other 1099 concerns in QBO, I'm always ready to help, nu.laceygordon. Take care and I wish you continued success.
