How to Update a Vendor's EIN Directly in QuickBooks Online

Correct a vendor's Tax ID directly in QuickBooks Online, outside of the Financial Cents W-9 workflow.

If you need to correct a vendor's EIN outside of the W-9 request workflow, you can update it directly in QuickBooks Online. This is useful when you already have the correct EIN on hand and don't need to collect a new W-9 through Financial Cents.

Update the Tax ID in QuickBooks Online

  1. In QBO, go to Expenses (some accounts show this as Expenditures or Expenses & Bills) > Vendors, then click the vendor's name to open their profile.

  2. On the vendor's Details tab, click Edit to open the editable fields.

  3. QBO masks the Tax ID field for security. If the vendor already has a Tax ID on file, you may be asked to verify your identity via a text/email code or by re-entering your login before the field becomes editable.

  4. Enter the correct EIN in the Business Tax ID (or Tax ID) field. If the vendor is also being reclassified from an individual (SSN) to a business, toggle the vendor type to Business first so the field expects an EIN format.

  5. Click Save to apply the change.

💡 Pro Tip: If you're also collecting a new W-9 from the vendor, you can handle the EIN update and W-9 upload together in Financial Cents — see How to Update a Vendor's EIN with a New W-9 in Financial Cents.
