ONL038 Export Error in QuickBooks Online Integration

If you see the error:

ONL038: Tax calculation error.

This means QuickBooks Online encountered rounding differences when tax was exported as a Journal Entry, preventing the export from completing.

Why the ONL038 Export Error Happens in QuickBooks Online

The ONL038 error typically indicates:

• Tax amounts are being exported as a Journal Entry.
• QuickBooks Online applies different tax rounding rules.
• Rounding differences caused validation to fail.

When exporting tax as a Journal Entry, QuickBooks may calculate tax differently than Expensify. These rounding differences can trigger export errors.

Exporting as a Vendor Bill allows QuickBooks Online to handle tax calculations internally, reducing rounding conflicts.

This is a QuickBooks Online tax handling limitation, not a Workspace calculation issue.

How to Fix the ONL038 Export Error

This issue can be resolved by changing the export type.

1. Go to Settings > Workspaces.
2. Select your Workspace.
3. Click Accounting.
4. Click Configure.
5. Open the Export tab.
6. Under Reimbursable expenses, select Vendor Bill.
7. Click Save.

After updating the export type, retry exporting the report.
