VAT Rounding Up

We have noticed that VAT is rounding up more than 1p

eg: 5 x £0.69 = £3.45 Tax shows as £0.60

However at 20% UK VAT it should be £0.575, although I can understand if it showed £0.58, but rounding it up 2.5p seems a little exessive.

Does anyone know why and how we can rectify this?


This has been resolved.

Change Tax Calculation from Unit Price to Subtotal.
