Difference between Tax Amount and Base Tax Amount

Question

I am curious to what the difference is between Tax Amount and Base Tax Amount. I have dumped to the system.log the values of each and the Base Tax Amount is coming out a penny more than the Tax Amount.

Any insight on these two fields is greatly appreciated, and any ideas on why the two are different values is even more appreciated =]

Thank you!

Jeff

Answer 1

Base tax amount (actually any field that starts with base_) is the value in the default store currency.

Tax amount (like other amount fields) is the value in the selected store currency.

If you have only one currency on your website then base_X and X should always have the same value. It's really strange that you get even 1 cent difference. Probably it has something to do with rounding prices.
