Incorrect tax calculation with Gift Certificate

Hi all!

I confess that I did not read all threads in here before posting this. So just redirect me if the problem has already been submited.

I get wrong tax calculation when using gift certificate:

I give an example with an order of two articles of 8 EUR each: 8 = 6,69 EUR + 1,31124 EUR (French TVA 19,6%).
Shipping is 5,1 EUR.
The Gift Certificate has a value of 20%.

Order without GC:
Sub-Total: €16.00

Table Rate (Best Way):€5.10

TVA 19.6%:€2.62

Total:€21.10

Order with GC:
Sub-Total: €16.00

Table Rate (Best Way):€5.10
Gift certificate: -€3.23 shoud be (16 X 20%) = 1,6

TVA 19.6%:€1.58 ????

Total:€16.86 ???

Any help?

Correction:

Gift certificate: -€3.23 shoud be (16 X 20%) = 3,2

Note that I have the same error when shipping is 0.

Lots of posts on this one...

It's a bug in the module.

Try setting ot_coupon, reset tax as a CREDIT NOTE.

Look for other posts & threads.

Thank you for your quick reply!

I found the following thread helpfull : 1.3.5 coupon tax calculation and fix .

The solution to my problem was to configure the Gift Certificate module with the following options:

• Sort order: 280 (default)
• Include shipping: false (default)
• Include Tax: true (default)
• Re-calculate Tax: None
• Tax Class: TVA

Not a bug. Just a training matter...

Test it again with SEVERAL products in the cart...

With just ONE product, the tax calc is correct. with SEVERAL products, the tax calc is known to do funny things.
