Free shipping for an order which total is more than some value

I need free shipping for an order wich total is more than some value BUT to be calculated after the taxes applied to the order total.

For example i enter free shipping more tha 50 euros but the “50” to be after the taxes.

Thanks for any hint where i should check to modify the code.

thanks very much!

You can do this out of the box. No code editing necessary.

Just setup your shipping and tax accordingly, shouldn't be too hard.
