What is US Sales Tax, and How is it Different From VAT?
If youβre a business owner residing outside the United States, youβre probably familiar with the concept of a Value Added Tax (VAT). Most countries that use a VAT sales tax for ecommerce businesses follow a centralized tax structure determined by their federal government, such as Germany, Australia, and Canada.
The US follows a different playbook.
The US has no centralized sales tax at the federal level. Instead, this responsibility is delegated to the state and local levels. States are free to determine their own sales tax rates with a few exceptions (the NOMAD states).
What This Means For You
The fact that each state can set its own sales tax rates adds a whole new level of complexity that your business has to contend with. A state like Delaware charges no statewide sales tax, whereas others might go as high as 10-11.5%.
A state-by-state system ultimately means you could have to collect sales tax for an ecommerce business even without a physical presence in the state if you cross certain thresholds. This could be a set number of transactions or a certain amount of annual revenue.
Do You Have To Collect Tax If Youβre Selling in the US?
It depends, but the answer is usually yes. Letβs take three typical cases to understand US sales taxes for international sales:
- No Physical US Presence, But You Do Sell to US Customers: If youβre a small to mid-sized business, youβre most likely in this boat. If youβre selling to US-based customers, you might be required to comply with state sales tax regulations.
It all comes down to thresholds set by different states. For example:- Kentuckyβs economic nexus threshold is 200 separate transactions or $100,000 in annual revenues.
- Alabamaβs threshold is $250,000 in annual revenues.
- Californiaβs threshold is $500,000 in gross annual revenue.
If youβre selling to customers in the US and are unsure of your nexus for sales tax for an ecommerce business, we strongly recommend consulting a sales tax expert for a personalized strategy.
- No Physical US Presence, and You Donβt Sell to US Customers: You donβt have to collect sales tax at all.
- Youβre a Non-Citizen Who Owns a Business in the US: Regardless of your citizenship status, if youβre managing inventory and selling to customers in the US, you most likely have to comply with your stateβs sales tax regulations. Note that US ecommerce sales tax rules might change, and you should stay informed of the latest amendments before making a tax-related decision.

How to Handle US Sales Taxes for International Sales
Whether youβre on BigCommerce or Shopify, you can follow these steps to handle sales taxes for your ecommerce business like a pro.
Determine Your Tax Nexus
This is the first and potentially most vital step to get right. Youβll need to identify your economic nexus before you can start filing sales taxes properly. To do this, youβll need to go over your sales data to identify states where your business has crossed the threshold and may have a nexus.
Note that mistakes at this stage can result in penalties and fines down the line. If youβre unfamiliar with the US business landscape, you can easily avoid errors by working with top-rated ecommerce tax experts like RJM.
Register For a Sales Tax Permit
If youβre meeting a state threshold for sales tax for your ecommerce business, you need to register for a sales tax permit.
This permit, also known as a sales tax license, will authorize your business to collect and remit sales taxes to local tax authorities. Failing to register in time will lead to penalties and even interest on unpaid dues, so earlier is better here.
The registration process for permits for US sales taxes for international sales will naturally vary from state to state. Youβll typically need to submit basic details like:
- Your businessβs name and legal structure
- EIN or a foreign tax ID
- Business address (this doesnβt necessarily have to be in the US)
- Sales volume in the state
- The type of products sold by your business
If youβre getting a permit to collect sales tax for your ecommerce business, you may have to pay a small fee depending on the authority youβre filing with. Texas doesnβt charge for a sales tax permit, while New York charges $7.
Collect and Remit Taxes
All thatβs left to do now that you understand US ecommerce sales tax rules is to collect and remit.
Set up your ecommerce platform to collect sales tax at the correct rate based on each customerβs location. This functionality should be built-in if youβre using a major platform, but you can always use apps and plugins to add and extend that functionality if needed. Youβll have to account for state, county, and city taxes, which can all vary in a given state.
If youβre selling through a party like Amazon, they can even handle tax collection for you.
Lastly, youβll have to remit sales tax for ecommerce businesses to your local authority on time to steer clear of penalties. Remember to keep records for future audits! If youβre worried about filing on time, you can easily automate tax filing with RJM.

Frequently Asked Questions
What is an economic nexus?
An economic nexus is more or less just a legal threshold that requires businesses to collect and remit sales tax if they meet it. This threshold can change significantly from one state to the next, so youβll need to know exactly where youβre selling to.
Do I need to register for a sales tax permit as an international seller?
You might be required to collect sales tax for ecommerce businesses even as an international seller if you meet state thresholds. You do not have to collect sales tax if you donβt have a physical presence in the US and donβt have an economic nexus in a state. US ecommerce sales tax rules can change, so you should look up the latest information before proceeding.
Do I need to register for a permit if Iβm selling through a marketplace?
Yes, in some cases. Marketplaces like Amazon and eBay are authorized to collect sales tax on your behalf. However, youβll need to register for a permit in states like Florida if you exceed $100,000 in independent sales (through your own website, for example).
