Mysterious Tax code

[alexrpaul]

On our invoices in the VAT summary at the base of the page we get two codes, one for VAT on goods code 301 and another for VAT on shipping.
The system correctly calculates the VAT on goods excluding for example books which are non VATable but for shipping it applies a tax code 501 which comes out with a four decimal percentage ranging from just above 17.5% to less than 10%.
I can't understand why or how this tax is being applied. We have always ignored it in the past because it is fairly marginal but now we want to link to sage we need it to be exact.

Maybe it is something to do with non VAT goods but even so with these items full VAT should be charged on carriage as it is a value added service. Also some of the orders with adjusted 005 tax %ages are on orders with just a standard VATable item.

Has anyone encountered this problem or could anyone shed light on it?

Thanks,

Is it 501 or 005, if it is 005 then it is custom tax.

Have you got any products with a set amount for the tax because if you have the percentage would be calculated on the fly, all custom taxes are reports with the same code but each one could have a different percentage value.
