No. The Form W-9 will only make it simpler to file taxes in the same way you have been doing before. VIPKID will provide a Form 1099 MISC in time for the next US tax filing season. It will include details about services provided to VIPKID, and payments made by VIPKID for the previous taxable year. This means it will be simpler for the IRS to determine how much tax you owe based on your individual situation. For more information please consult a tax professional.
