GST appears to not be Calculating Correctly

Posted on by Bill Campbell 12

I have an invoice that I am matching to a PO and it works perfectly - all values agree to the penny - except for the GST / TAX

The total dollar value of the invoice line items is 9,321.81 and at 5% GST would be 466.0905

When I look at the number GP (2015 R2) presents, the GST is 466.1350

Now we are not going to lose it over .04 but the important question is why.

What we know:

There are 40 line items

All 40 have GST - same tax detail - attached

When I review each detail line I get a total of 466.135

Anyone have a suggest as to why and that can be explained to a client that is a little concerned about how the system works already and now we see this happening.

    Hi Bill,

    I think what your seeing is the effect of the rounding option on the tax detail on a number of lines. GP will round the tax amount on each line, not on the transaction total, so it can make a difference to what you expect if you calculate the tax on the transaction total.

    If you go through and round the tax amounts for each line, based on the tax detail rounding option, it should come to a total of $466.1350.

    Cheers

    Ok, so what you are saying is that the TAX that is presented below the subtotal is the 'rounded affected' amount and that when I calculate 5% on the subtotal it is the different value.

    I get this, so, question - is there a way to drop this - so that is does not round ???

    Thanks

    Hi Bill,

    As far as I know there isn't a way to prevent this. There is no rounding option of do not round on the tax details and there is nothing in POP setup in relation to this either.
