Hello,
We apologize for the issue you are facing regarding the VAT charge on your subscription. When upgrading to Rank Math PRO, the purchase may be subject to taxes like Value-Added Tax (VAT) depending on your location, even if you are a US-based LLC. This is due to our partnership with FastSpring, which automatically applies applicable taxes during the checkout process based on location and product type.
If you believe you should be exempt from VAT, you can claim a refund after completing your purchase by contacting FastSpring’s consumer support here. Additionally, you can enter your VAT identification number during the checkout process to potentially avoid these charges, as shown in the image below:

If you are still having trouble or if the option to enter your VAT ID is not displayed, please reply to this ticket with more details, and a human agent from our support team will assist you further.
Thank you for raising this concern, and we look forward to helping you resolve it!
