Discount after tax but the tax need to be lessened as well

[Kuubs]

I have a weird situation that I cannot seem to resolve with Virtuemart calculations.

Let's say I have a product of 100 euro. And I have 21% tax. This means that the product is 121 euro. Now when i apply a discount the final salesprice becomes 111 euro.  The tax of this product is 19,26. But my VatTax rule is not applied correctly. It is essentially calculating tax of that 100 euro, and then doesn't recalculate when a discount happens. How can I fix this?
Do I need to use another calculation method? Tax per invoice or something? But then the tax of the specific prodcut is not calculated. I find it all very weird.

I am using coupons for the discount!

Please tell is what You use, dbtax, datax and all your calculated data. This should work.

This bug is long time, sorry, we had to fix for every shops, which use invoice from VM (not for shops connected to ERP).
I remember how Max furiously defended the mistake in some discussion (I solved it in 2015, but it didn't solve it).
Since then, I have lost the illusion of a remedy and we always program the hack ourselves, unfortunately.

Hmm, once again, in my shop it works, How do you do it? I have still not seen all the numbers.

Org price: 95 sek (inkl VAT)
Vat: 25 %
Discount 50%
end price 47,50 sek
vat 9,50 sek = 20 % of 47,50 this is OK

Where is the problem ?

I do not see any problems.

Jörgen:

For acountant, the VAT must be still 25% after discount == then calculation for VAT for discount is wrong == must be recalculate after discount again

[Jörgen]

Did You Read My figures

[pinochico]

To Jorgen:

I Read Your Figure

Org price: 95 sek (inkl VAT)
Vat: 25 %
Discount 50%
end price 47,50 sek
vat 9,50 sek = 20 % of 47,50 this is OK

And our accountant put this in my head and say - what the hell is your shop? I created, then my shop and my mistake
Is totaly wrong and calculating not function for financial goverments.

100 - basic price
121 - sales price with 21%VAT
111 - final price with discount 10 EUR

basic price - must be recalculate - 91,735537190082645 (111 * 100 / 121)
vat after discount (21%) - must be recalculate - 19,264462809917355 - finally not really in VM

Your example - change VAT from 25 to 20. And this is big mistake
But for us is not mother, we fixed in ERP and if some clients wants invoice from VM, then we recomended external online invoicing, not VM
We don't waiting. Not anymore, otherwise we would never see it, sorry.

[Jörgen]

You really did not read my figures.

VAT is 25 % to be added on price without VAT which equals 20 % of total customer price.

Original VAT = 20% OF price = 19 sek (25 % added on price without VAT)
VAT after discount = 20% of discounted price = 9,5 sek (25 % added on discounted price without VAT)

Please do not waste my time any more.

I use the following:

VatTax.

And I also have DATax discount in the VM itself. But it's going wrong when people use Coupons!

[Jörgen]

OK, this is new information, native VM coupons or AwoCoupon?

I can not remember I have had any problems with AwoCoupon.

Native coupons! I thought I was clear in my OP, lets double check taht again.

[Jörgen]

Sorry missed that.

I only read, added discount.

Jörgen

[Jörgen]

Tested with 10 % native coupon.

Works for me

Screenshots would probably help.

What kind of screenshots?

I have a product with 21% VatTax. I also have a DATax discount code of 15 euro. When I add a discount code for 10% the Tax is wrong. Please let me know what kind of screenshots you need!

[Jörgen]

A screenshot of the checkout that shows the figures that are wrong. It is hard to guess, since my figures all seem to show correctly
