Hi there,
This kind of problem is usually caused by a conflict with your theme or with another plugin. The best way to determine this is to:
- Temporarily switch your theme to Storefront
- Disable all plugins except for WooCommerce
- Repeat the action that is causing the problem
If you’re not seeing the same behavior after completing the conflict test, then you know the problem was with the plugins and/or theme you deactivated.
Reactivate the theme first and check again. Then, go on and reactivate your other plugins one by one, testing after each, until you find the one causing conflict.
You can find a more detailed explanation on how to do a conflict test here: https://docs.woocommerce.com/document/how-to-test-for-conflicts/.
Let us know how it goes.
Hi thank you for your answer.
– I already using Storefront.
– Only have WooCommerce plugin working.
– Tried to change to different themes not working.
Maybe is VAT calculation formula is bad? I mean is to simples to calculate ex: 100*0,23 to know VAT value, or 100*1,23 to add VAT to value. :/
I really trying for days!
Do you have any suggestions?
Thanks.
I found something interesting
Imagine you have a value without VAT like = 376,33€
If we add 23%VAT on value in the top it will be like: 376,33€ * 1,23 = 462,8859€
What is happen when WooCommerce add 23%VAT it will be like = 376,33€ + €70.41 = 446,74€
Okei to here we understand that is really bad calculation but wait if we add VAT23% 70.41€ magic happen we get a result of 86,6043€
And to the final result, we have 376,33€ + 86,6043€ = 462,9343€ is a result than we need!
So here’s whats happens when WooCommerce calculates VAT its forget to add VAT to the VAT calculated. Its mean that when we get a result of VAT we need to add VAT to this result to get the final real VAT.
Hope you understand the explanation.
Hi @alibaba761,
Thank you for this additional information! It is possible that the tax setting in the back end – we might be able to try to replicate it on our own side, but without knowing what is exactly on the site it is hard. If it is OK, Could you please share a copy of your site’s System Status? You can find it via WooCommerce > Status. Select “Get system report” and then “Copy for support”. Once you’ve done that, paste it here in your response. Also, if possible let us know what the tax setting is under WooCommerce > Settings > Tax.
This allows us to see if there are any custom plugins for tax, as well as the setup of the Tax area so we can try to replicate and see why WooCommerce is behaving like so.
We look forward to hearing back from you!
Hello,
Thanks for the awesome support, I think everything works fine atm.
I changed some settings and turned off the TAX calculation.
