Reason Code 76: "The tax amount is invalid."

[mmcdonald]

Hi all, using the PHP SDK I have the following:

$transaction = new AuthorizeNetTransaction;
$transaction->amount = $amount;
$transaction->tax->amount = 19.8000;
$transaction->tax->description = 'UK Value Added Tax';
$transaction->customerProfileId = $customerProfileId;
$transaction->customerPaymentProfileId = $paymentProfileId;

The creation of the customer profile and payments profile works, but the transaction fails with the error mentioned in the subject.

I have tried:

• '19.80'
• 19.80
• $amount * 0.2
• 19.8000
• "19.80"
• 19.8

Any thoughts? The docs state The value submitted in x_tax failed format validation, but I don't think that's true.

Thanks,

Michael

the x_tax have 3 components

name, description, and amount, my guess it that it need the name.

Thanks, I thought it was optional, but I think that's a lack of clarity in the docs. The API docs say it's optional period, not required if another value is provided. Thanks for the clarification!

The documentation says the structured tax item is one format, but the other format is pure numeric. After years with no problem, today I received an error with text "The tax amount is invalid". I am using simply "0". Maybe a decimal is now required. I will be searching for a more precise format description, and/or testing with "0.00" as the tax amount. But it sounds like you have tried a number of formats already.
