Reverse charge VAT (Ireland)

[cruiser]

I understand that the new version of Sage 50 now incorporates the reverse charge on vat that is in place in Ireland.
Can anybody give advice on how to input this on older versions?

The regulations are that a Sub-Contractor will invoice the Principal contractor a NET price and the Principal Contractor will then account for the VAT and if appropriate can then claim it back.

Any assistance would be appreciated otherwise it is a manual entry each period of VAT or biting the bullet and buying the new version.

Well, generally this would be a nominal journal. Calculate the amount of VAT that should have been charged, and raise a nominal journal CR Sales VAT, and DR - well, either Purchase VAT or an expense account for "VAT not recovered". The only thing I'm struggling with is how, if VAT was chargeable on the supply to the principal, and he has to account for that, there could be any conceivable circumstance under which he couldn't claim it as input tax. But I am not an expert on Irish VAT.
