I want to apply for a withdrawal, but I receive an official email notification that I need to pay income tax!

Starting from 2/18, about 240,000 USD were deposited successively, and until 5/15, the accumulated income was about 260,000 USD. During this period, there were attempts to withdraw 3,100 USD, and all of them were withdrawn normally. As a result, due to capital requirements, the application for withdrawal of 10,000 USD was made. , but received an official email notification the next day, requiring payment of 20% of the income, more than 50,000 USD, and then the progress of the withdrawal was stuck in processing. After contacting and inquiring according to the official line account paid in the letter, the reply is that the tax payment certificate is required for the withdrawal application process before the withdrawal. It is suspected of scam on the fraud platform, please help to retrieve the funds.
