I think you also received the following email about earning money on Youtube. It says that if you don't enter your tax information, a 24% U.S. tax will be deducted. The email came in English, here is the translation below. Does anyone have accurate information about this? Hello, Contacting you because Google will need to withhold U.S. taxes from payments made to content creators outside the U.S. later this year (as early as June 2021). In the coming weeks, if applicable, we will ask you to submit your tax information to AdSense to determine the correct amount of tax to be withheld. If your tax information is not provided by May 31, 2021, Google may need to withhold up to 24% of your total earnings worldwide. What do I need to do? In the next few weeks, you will receive an email to submit your tax information to AdSense. The online tax tool in AdSense is six steps and will guide you through a series of questions to determine if any U.S. taxes apply. Visit our Help Center for more information on these changes and a list of tax information to prepare. Why is this happening? Google is responsible for collecting tax information from all content creators earning money outside the U.S. and may need to withhold taxes under certain circumstances when revenue is generated from U.S. viewers, as required by Section 3 of the U.S. Internal Revenue Code. For content creators outside the U.S., the earnings from YouTube will be considered as royalties from a U.S. tax perspective, and we will soon update our Terms of Service accordingly. This could affect how your earnings are taxed, and Google will withhold taxes as mandated by U.S. laws. How will it affect my earnings? If you provide your tax information, U.S. taxes will only apply to your monthly U.S. earnings from AdSense (revenue from ads viewed by U.S. viewers, YouTube Premium, Super Chat, Super Stickers, and Channel Memberships). If no tax information is provided, your tax rate may default to a higher individual backup withholding rate (24% of total earnings worldwide). Follow these instructions to estimate the potential impact on your earnings. Thank you, YouTube Team
