Override a transaction

AvaTax provides a TaxOverride method for overriding calculated tax. This method can be specified at either the document level or line level of a transaction.

When creating transactions that will calculate Use Tax, use a taxAmount override and specify the type as VendorChargedTax. This setting determines how AvaTax will handle vendor-charged tax. Usually, this override is done at the document level. It's possible to specify a vendor-charged tax override at the line level. If you specify a vendor charged tax for at the line level, then you must specify this for all line items. You'll receive an error if you have multiple line items but only specify a vendor-charged tax override for 1 line. If your additional lines don't require an override, pass a vendor-charged tax override with a tax amount of $0.00.

Example

...,
  "taxOverride": {
    "type": "VendorChargedTax",
    "reason": "VCT Reason",
    "taxAmount": "42"
  },
