How To Fix ( this traction has been modified since last file tax return )

Thank you for bringing this up, vr6turboguru. Let me help you with the warning message you’re seeing regarding your modified invoice in QuickBooks Desktop (QBDT).

This message appears because the transaction was already included in your previously filed tax return. QuickBooks detects that the transaction has been modified since the tax filing. This triggers this warning to prevent discrepancies in your tax records.

Since the tax return has already been filed and the taxes for those transactions have been paid, I recommend contacting our Live Support team. They have the specialized tools and expertise to help you make the necessary adjustments and changes, ensuring that your records remain accurate and compliant with tax regulations.

Here's how to contact them:

1. Log in to your QuickBooks Desktop.
2. Go to Help, then select QuickBooks Desktop Help.
3. Enter a brief description of your concern.

For your convenience, please refer to this article to check their available support hours: Get help with QuickBooks products and services.

Additionally, you can also generate the Sales Tax Liability to help you keep track of the sales tax you've collected and owe to your tax agencies.  

Here's how:

1. Navigate to the Reports menu.
2. Select Vendors & Payables.
3. Click Sales Tax Liability.

Please feel free to reach out to us with any other questions or concerns beyond the warning message you received, vr6turboguru. We’re always here to help!
