Price List including TAX

Question

Hello experts
I have a Price List that includes Tax. At present, if I raise an Invoice, SAP will automatically add Tax to each line however, what I would like to achieve is the following:
1. No Tax should be added.
2. The Price List amount should be worked out backwars as follows:
Tax Rate = 20 %
Item Price in Price list  Item001= 120
A/R Invoice line = Item001 Gross = 120, Item001 Tax = 20, Item001 Net= 100
How can I achieve this so the Price List is automatically split into Net + Tax = Price List priice.
The reason for this requirement is that we publish our prices to the public and these include VAT, so we need to end up exactly with the same price as our published price.
Thank you for your help

Hello Robert...
Believe it or not, I have been thinking about this thread since it was posted - I once implemented SAP B1 for a company who had a veritable walking Tax Standards as their CFO.  Everything this fellow discussed somehow ended up as a discussion about taxes!  He required a taxation projection similar to what you described - it took us some time but we came to the penny for what he was looking for.  So before answering with a rather complicated reply, I think there might be a way depending upon the combination of the answers to the following (not being an expert in British taxation):
A few questions for you:
1.  Is the VAT always a set figure of 20% (or can it vary from area to area as it does here in the US)?
2.  Is the publication sent to your customers created from SAP B1 (or externally by sales personnel/management/etc)?
3.  Do you use the internal SAP B1 Tax Report (or is it exported/manually created)?
4.  Does your company have a policy that allows over/underpayments of invoices?
5.  How many decimal points do you have on SAP B1 for your product and documents?
6.  Are variances allowed by the taxing authorities (or does it have to be penny to penny in sales and taxes collected)?
Still thinking here and might work out some drafts this weekend, depending upon your replies I would work one up.

PS - is this the Robert from the famous thread once posted in 2009 where an SAP person asked if we had seen the latest and greatest in SAP B1 land?  I believe that Robert had a real uphill battle getting SAP B1 working in his company because the initial partners did not understand the nominal accounts and other items.  If so, I have a funny story to share with you from May (the last time I was in Waldorf Germany - send a note to zalparchem-at-bellsouth-dot-net for that).
