Tax Rounding Problem

[tjblaat]

Hi

 

I'm busy finishing my webshop and I have one problem with tax calculations.

version: 1.6.1.4

 

I'm not able to solve it with the round up/round type

 

for example:

I have an item 

 

24,75 without tax

29,95 (with tax 21%)

 

The site shows the right prices incl tax

So 29,95 (euro) incl tax

 

If I buy 1 products. Everything is fine

But if I buy three, then the price should be 89,85 incl tax.

But it shows 89,84 (because of rounding the prices)

 

The option to use round type "round on each product" is not the solution.

I get the right price incl tax. But the tax calculation aren't right. I need to calculate the tax over the total price.

Playing with the round mode doesn't solve it either.

I can...add more decimals to the product price. But that will only cause the problem to happen at higher amounts. It won't happen at 3 parts anymore, but at 50+ (for example).

 

 

So I think I came up with a solution

 

- set product price at (for example) 24,75

- set rounding type a "round on each product". This way it shows the right price incl tax on the site.

- The total price in the cart with also be right (because it uses 29,95 (incl tax) times the quantity. 

- tax calculation won't be right, because it calculates tax on each product (and I need tax on the total price)

 

Is this possible?

Let the cart calculate the tax based on total price incl tax instead of each product.

 

Or is there a way to set product prices incl tax? (and I don't mean incl tax on the front end, but in the backend at the product settings)

You have available 6 round modes and 3 round types. That's all you can use.
