重要： 本页信息不构成税务、法律或其他专业建议，也不得用作此类用途。如有疑问，请咨询您的专业顾问。
要计算任何非商城征税州或管辖区的税费，您必须在相应的税务机构进行注册，获得税务登记号，然后才能收取任何销售税和使用税。
亚马逊的税务计算服务需要您提供州税务登记号，才能为您想要启用该服务的所有管辖区进行税务计算设置，从而计算您商品的销售税和使用税。
如果您注册了精简销售税税号 (SSTID)，那么各州还将签发一个与您的精简销售税注册相关的唯一州税务登记号。在设置税务计算服务时，只能使用各州签发的唯一州税务登记号。您的精简销售税税号用于在“精简”计划内进行沟通时使用，请勿在设置税务计算服务时使用精简销售税税号。
如果您有州税务登记号，便可继续设置税务计算服务。
卖家有责任履行在所有州或税务管辖区内可能要承担的任何缴纳和/或申报义务。
如果您对在某个州注册、获取州税务登记号、税务缴纳或申报义务有任何疑问，请联系您的税务顾问和/或相应的税务机构，获取更多信息。

State Tax Registration Numbers
Important: Information on this page does not constitute tax, legal, or other professional advice and must not be used as such. You should consult your professional advisers if you have questions.
To calculate tax for any non-Marketplace Tax Collection state or jurisdiction, you must register with the appropriate tax authority to obtain a tax registration number before collecting any sales and use tax.
Amazon’s Tax Calculation Service requires your state tax registration number to set up tax calculation settings for any jurisdiction you would like to enable to calculate sales and use taxes on your products.
If you registered for a Streamlined Sales Tax ID (SSTID), individual states will also issue a unique state tax registration number in connection with your Streamline registration. Only use the unique state tax registration number issued by each state when setting up your Tax Calculation Settings. Your SSTID is for communications within the Streamline program, do not use your SSTID for your Tax Calculation Settings.
Once you have your state tax registration number, you can move forward with Setting up Tax Calculation Services.
Sellers remain responsible for any remittance and/or reporting obligations they may have with any state or taxing jurisdiction.
If you have any questions about registering with a state, obtaining a state tax registration number, remittance, or reporting obligations, contact your tax advisor and/or the specific tax authority for additional information.
