Hi Hugh,

The short answer is that if you are importing an invoice with a Distribution code on the detail that is defined as a 'Tax-included distribution', it is possible to import an expense amount that includes taxes, and a tax amount that is either automatically calculated or specifically determined in the import file that overrides this calculation. This note is from the Help file for import invoices notes:

Det-Tax Amount/Base: For overriding tax amount on Tax included purchase distributions or tax base on Tax distributions. Import 0.00 and these amounts will be calculated from the tax rate on the Distribution code.

Discussing how to do this in the most efficient and correct manner in the way your company requires is best handled with your Adagio consultant.
