Project Description

I don't know if your familiar with the VAT taxes from the UK but there is a bug in magento that is causing it to report incorrectly. I would like to have a extension written that will fix the issue.

Here is some information on the issue

This is affecting currently all versions of Magento (1.0 thru 1.2.x)

I think this hasn’t gotten much attention because its somewhat hard to understand and many online store owners aren’t familiar with how traditional cash register’s / tax calculation works. .. Let me clarify this bug which again applies to all versions of Magento:


WHAT IS HAPPENING NOW: Magento is taxing products individually, rounding the tax and then adding the tax and making it the Total Tax

Item price * Tax Rate = rounded(Tax)

Item price * Tax Rate = rounded(Tax)

Item price * Tax Rate = rounded(Tax)

Item price * Tax Rate = rounded(Tax)

Total tax is the sum total of all the rounded taxes.. BUT rounding shouldn’t happen per item

IT SHOULD BE: Calculating tax based on the subtotal (of taxable products), then rounding the total tax and adding that to the grand total

[[ Begin Taxable good items ]]

Item Price

Item Price

Item Price

Item Price

Item Price

[[End Taxable good items

* Tax Rate

= rounded(Total Tax for the Order)

SO HOW DOES IT AFFECT STORE?: Result is your customers are being charged more/less tax than they should be charged.

OTHER RELATED ISSUES: This is also what is happening with discounts.. it appears this issue is related to how discounts are being calculated.

Let me know if this is something you could do for me
