Understanding 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. Consult your professional advisers if you have questions especially on understanding state text registration.

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.

Why State Tax Registration Numbers are Necessary

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.

Getting Started with Tax Calculation Services

Once you have your state tax registration number, you can move forward with Setting up Tax Calculation Services.

Responsibilities of Sellers

It's important to note that sellers remain responsible for any remittance and/or reporting obligations they may have with any state or taxing jurisdiction. Failure to comply with these obligations can result in penalties and fines. Therefore, it's essential to understand your responsibilities and ensure timely compliance.

Seeking Professional Advice

If you have any questions about registering with a state, obtaining a state tax registration number, remittance, or reporting obligations, it's advisable to seek guidance from your tax advisor and/or the specific tax authority. They can provide you with tailored advice based on your individual circumstances and help you navigate the complexities of tax compliance.

Professional Amazon sales people.We connected with them in 2020 already in the second month we felt the change. - Turnover doubled and advertising expenses decreased.We immediately felt the professionalism of the team.Today in 2022 our turnover is 5 times since we started with them.Regarding the team: they have a great content writer, graphic artists and campaigners. The support staff speaks English.Contacting the service was done with the help of WhatsApp, email and phone. - always available.Their work plan is annual and they know how to manage the advertising budget wisely.Their team performs actions and measurement and sometimes the results of a certain action are seen only after 4 months.They never forced us to stay with them for support and always gave us confidence that the control was in our hands.The owner is always pushing our business forward.Thanks to them today we manage stores in Walmart, Etsy, Shopify and WordPress.Our brand has tripled its value.This is a boutique store management company in the USA that puts the customer at the center.recommend
