## Official rule text

Seller tax representative name shall occur maximum once, if the Seller has a tax representative

## Why did my invoice fail UBL-SR-22?

The Seller tax representative name (BT-62), in cac:TaxRepresentativeParty/cac:PartyName/cbc:Name, names the fiscal representative acting for the seller and may be given at most once when a tax representative (BG-11) is present. A seller has one tax representative, so only one name is valid.

## Common causes

- Two cac:PartyName elements are emitted under cac:TaxRepresentativeParty.
- Both a legal name and a trading name of the representative are written.
- The seller name is duplicated into the tax representative party.

## How do I fix it?

```
Use one name: <cac:TaxRepresentativeParty><cac:PartyName><cbc:Name>Fiscal Rep GmbH</cbc:Name></cac:PartyName>...</cac:TaxRepresentativeParty> and remove extra PartyName elements.
```
