PDF Upload Error: Taxable Amount Doesn’t Match Invoice Subtotal

This error appears when the numbers entered in the tax section don’t line up with the rest of the invoice. This usually happens because a required amount is missing, a value was entered in the wrong field, or Brightflag’s auto-calculated totals were overridden.

Follow the steps below in order to resolve the issue.

Step 1️⃣ Confirm All Required Fields Are Completed

First, check for any fields highlighted in pink or red.

• These fields must contain a value before submission

• Brightflag will not allow submission while required fields are incomplete

Step 2️⃣ Check the Taxable Amount and Total Amount Fields 

What to check

• In the Taxable Amount field, enter the portion of the invoice that the tax applies to

  • This is usually the invoice subtotal before tax

• Leave the Total Amount field blank

Why this matters

• The Total Amount is auto-calculated by Brightflag based on the tax rate you select

• Manually entering a value here can cause totals to mismatch

Step 3️⃣ Complete the Tax Section Even If Tax Is 0%

The tax section must be completed even when no tax applies.

What to do

• Select a Jurisdiction

• Choose a Tax Type (usually Exempt)

• Select a 0% Tax Rate

• Enter the invoice subtotal in the Taxable Amount field

• The Total Amount will auto-calculate to 0

➡️ If a 0% tax rate is not available, move to Step 4.

Step 4️⃣ Confirm the Required Tax Rate Exists

If the tax rate you need isn’t available in the dropdown, entering a different value can cause this error.

What to do

• Contact your client to request the correct tax rate

• Once approved by the client, Brightflag Support can configure it

➡️ Do not substitute another tax rate to bypass the error.

Step 5️⃣ Check for Duplicate Tax on the Same Amount

In more complex invoices, multiple tax lines may be added.

What to check

• The same amount is not being taxed more than once

Important

• Brightflag does not support taxing the same amount multiple times

➡️ If your invoice requires multiple tax lines on different portions of the invoice, contact your client for guidance on how the tax should be structured.
