Payment Notification with Tax deductions

Hi List,

My company is currently designing a web system for Payment Notification here in my country, Colombia.

Technically, it will be backed by an XML database and, personally, I want to recommend that we use UBL as the standard to represent the payment notifications.

We have an special requirement due to the nature of our Tax system: here in Colombia, the government require to the big companies to collect taxes when they pay to the smaller ones. The system is known as auto-retention and may vary depending on the location, amount and kind of transaction.

Behind this tax system if a customer is going to pay to a provider an invoice of COP $100, the provider receives only $90, the other $10 are transferred from the customer to the govt. tax agency (its name is DIAN), and for the end of fiscal year, the provider can deduct those $10 from his taxes.

The whole system is a bit complex because the customer can collect this taxes for the national government and also the city govt.

So the Accounting Party needs to inform to the Payee Party, not only the amount paid, but also the auto-retentions made, so they can know how much to deduct from the taxes.

I've been studying the RemittanceAdvice specification but I can't find how to include on it information about the taxes deducted from the payment (kind, percentage and amount).

Can somebody give me some advice if I can use the RemittanceAdvice for this case?

Thanks in advance,
