# BT-110 — Invoice total VAT amount

> https://billhorse.com/en/terms/bt-110/

Total VAT of the invoice in the invoice currency. Must equal the sum of the VAT amounts of all breakdown categories (BG-23) — with multiple rates, round each category first, then sum.

## Practical note

In CII, ram:TaxTotalAmount carries a currencyID attribute; the value in the invoice currency (BT-5) is BT-110. In UBL, BT-110 sits in the TaxTotal that holds the TaxSubtotals.

## Where does it live in the XML?

- UBL: `cac:TaxTotal/cbc:TaxAmount`
- CII: `rsm:SupplyChainTradeTransaction/ram:ApplicableHeaderTradeSettlement/ram:SpecifiedTradeSettlementHeaderMonetarySummation/ram:TaxTotalAmount`
