Proposal

The functionality in Adempiere is targets at supporting sales tax - i.e. taxes on sales. In Europe, and many other parts of the world, governments implement consumption taxes such as VAT (Value Added Tax), IVA, GST (Goods & Services Tax). Adempiere handles these in transacting, but the reporting for input and output taxes could be improved.

I propose to implement the changes we have made in order to support VAT in the UK. These include:

  • extending C_TaxDeclaration in include IsSOTRX
  • extending MTaxDeclarationLine to support correct signage of input and outputs
  • extending the Tax Declaration Report to summarise by input and output and group by tax to provide relevant totals to complete a VAT return

Project Specifications

The images here show an example of a VAT report (with some details deleted).

In the images, the text in red indicate the figures to use in a UK VAT return as follows:

1 - VAT Due in this period on sales and other outputs 2 - VAT due in this period on acquisitions from other EC member states 3 - Total VAT Due (1 + 2) 4 - VAT reclaimed in this period on purchases and other inputs 5 - Net VAT (3 - 4)

6 - Total value of Sales and other outputs excluding VAT 7 - Total value of Purchases and other inputs excluding VAT 8 - Total value of all Supplies of goods and related costs excluding VAT to other EC member states 9 - Total value of all acquisitions of goods and related costs excluding VAT from other EC member states

The new VAT report shown here provides figures for boxes 1,4,6 & 7

If EC VAT Exemption (tax rate) is used, then the figures for 2, 8 & 9 are also displayed.

This provides the total requirement to complete a UK VAT return.
