Manage Your Account

Thanks for reaching out, kerkurgel. Updating your Tax Registration Number (TRN) in the Accounts and Settings will not automatically update and show the TRN on your invoice forms in QuickBooks Online (QBO).

 

This could be because the TRN displayed on invoices is pulled from your Custom Form Style. To update it, you’ll need to manually edit your invoice template and replace the old TRN with your new one.

 

Here's how:

 

  1. Navigate to the Gear Icon.
  2. Select Custom form styles.
  3. Choose the specific template for your invoices, and click Edit.

  4. Go to the Content tab, then click the section where yourTRN shows on the invoice(usually in the header section).
  5. If the TRN is shown in the Header section and you have used the Company Registration Number for your TRN, replace the old number with the latest one.
