Ecommerce owner

Ecommerce sellers used to have a pretty easy time when it came to sales tax, but those days are gone. 

In June 2018, a landmark case turned the tide on sales tax collection for good. The Wayfair vs. South Dakota ruling redefined the criteria for business owners eligible to pay sales tax. 

Prior to this ruling, business owners needed physical presence in a state to be considered eligible to remit sales tax. This is no longer the case. 

Ecommerce has become worth so much money that the physical presence rule became outdated. Business owners that cross a certain revenue threshold in any state, regardless of their location, may now be eligible to pay sales tax to multiple states. 

This eligibility is referred to as “economic nexus”. The rules around nexus differ in every US state, and are also affected by where your buyers live, where you live, and where you store keeps inventory - among other things. 

In addition to ecommerce sellers now needing to pay attention to taxes, so do the marketplace facilitators. Numerous states have enacted legislation that requires sites like Amazon, eBay and Walmart to remit tax on behalf of sellers, which is far easier for the states to administer than tracking individual sellers themselves.

If you’re scratching your head here, you’re not alone.

In this guide, we take you over the basics of sales tax and what is expected of you. We have also created in-depth guides unique to each selling platform so that you can get as much information as possible to nail your taxes.

Please note, as these regulations are fairly new and still evolving, always go to an accountant or the official sites of each state for the most up-to-date and relevant information. We have a directory of trusted accountant partners here

Basic Tax Terminology 

Ecommerce sales tax is so complex, it almost needs its own dictionary. Here’s a quick explanation of the most common terms associated with sales tax in the US and Canada:

  • Ecommerce sales tax: Sales tax related to an online sale. It’s a consumption tax added to the retail price of your products, and your customers pay the tax when they make a purchase. 

    In the US, there is no national sales tax because it’s governed at a state level. Ecommerce sellers find themselves dealing with different tax laws and rules in each state. In Canada, it’s a federal-level tax called GST.

  • Local sales tax: on top of the state-level sales tax, some local municipalities also charge a sales tax. In Canada, you have local-level taxes for the 10 provinces only.

  • Total tax rate: State and local sales tax combined.

  • Sales tax nexus: Nexus refers to an economic link with a state. You will be considered to have a strong enough link that it counts as nexus when your business meets a revenue threshold set by that state.

    If you’re an ecommerce retailer, and you have nexus in a state, then you must register, collect and remit sales tax. Each state has its own conditions for what creates sales tax nexus.

  • Physical nexus: Your business has a physical presence in a state – for example, a store, inventory, staff, or third-party providers – making you sales-tax liable.

  • Economic nexus: Your business has an economic connection to a state. Some states have an economic threshold you need to reach before you charge and pay sales tax. This might be transaction or gross sales based, and again, changes from state to state.

  • Origin vs. destination-based states: This refers to how states determine the rate of tax a seller remits. If a state is origin-based, then the seller needs to collect the rate of tax for their local jurisdiction.

    If the state is destination-based, as most of them are, the seller needs to remit the rate of tax of their buyers’ local jurisdiction. As you can imagine, the latter is a lot more difficult to keep track of. 

  • ‘Carrying on business’: Canada’s version of nexus.

  • Taxable products: Not all products are taxable, meaning you don’t add sales tax to their price. Most tangible personal property is taxable, but each state may have its own exceptions.

5 Simple Steps to Ecommerce Sales Tax Compliance in the US and Canada

  1. Determine where you have economic nexus. 

To do this, list the states where you sell, store inventory, have any employees, and include where you live. Check their nexus threshold and figure out whether you meet this. For all the states whose threshold you meet, you have economic nexus there.

Find a table with these rates in our eBay Sales Tax Guide here under “A Comparison of the US States for Sales Tax".

  1. Determine whether your products are taxable. 

Establish if the products you’re selling are taxable in each state. These may differ by state, so ensure you have checked the official sites of each. Links to these sites can also be found in the eBay Sales Tax Guide, in the same table referenced above. 

  1. Get registered. 

Get compliant, and register for a sales tax permit in your nexus states. This is usually done through the state’s tax authority. It’s illegal to collect sales tax without a permit.

  1. Collect sales tax. 

As mentioned above, marketplace facilitators are now required by many states to collect tax for you. Where this is the case, ensure that you have correctly set up your sales tax collection settings on your ecommerce platform. 

If a state does not require the marketplace facilitator to collect sales tax, but you have nexus there, you may still need to collect, so make sure you do!

  1. File a return. 

Once you’re registered for sales tax, you must file a return on time, even if you’re reporting zero sales tax collected. Marketplace facilitators only collect sales tax; they don’t remit it for you.

In this article, which is the third in a series, we outline the options of filing for sales tax. 

Sales tax makes a lot of people nervous – accountants and ecommerce sellers alike – but as Michael Fleming from Sales Tax and More puts it, it’s not a big deal if you’re only selling in one marketplace (like Amazon), which does most of the work for you.

Michael says when it comes time to work with an ecommerce sales tax professional, make sure that person has the right experience and connections.

“It’s about the capability of who you’re working with. We have tax partners around the world in all the major markets – Australia and Europe – we handle the US and Canada, and we refer back and forth.”

In this article, we discuss the benefits in using a specialist ecommerce accountant, and what to ask them when finding the right fit for you.

Selling Overseas? There’s a Tax for That 

Ecommerce knows no boundaries – you can market, sell, buy, and ship to almost every corner of the world.

Unfortunately, sales tax isn’t just a US and Canada thing.

Europe (including the UK)

In Europe, value-added tax (VAT) is the equivalent of sales tax – with a few differences. It’s a general tax applied to all commercial activities, including production and distribution. 

Under EU law, each country can set its own VAT rate at or above 15%.

“Anybody who wants to trade internationally in the long-term should consult a professional tax advisor. Rules are changing all the time, especially with Brexit, and you’ll find there are new things you’re not aware of.”

- Melanie Shabangu, client-managing director for AVASK in London.

Hong Kong

Hong Kong has a relatively simple tax system with no sales tax, VAT or GST. You do, however, need to be mindful of profit tax – and whether this is something your business needs to pay.

What do the experts say is the most common mistake ecommerce sellers make in Hong Kong? Not filing their profit tax return on time.

Ray Ng from Unipro Consulting says to enlist the help of a local ecommerce sales tax professional.

“We have a typical case with a US client. He uses our service because his company is registered in Hong Kong. We take care of his tax obligations here, but he also has another accountant in the US to handle his global tax filing.”

Australia and New Zealand

For US-based ecommerce sellers, your main tax obligation in Australia is GST and this depends on whether you’re importing and storing goods, and your volume of sales.

“Ecommerce is a growth industry, and it’s complex, so you really do need to specialize in the area to understand the nuances and issues that sellers aren’t often aware of.”

- Jason MacDonald from White & Black Chartered Accountants.

Jason’s advice: get GST registered, ensure your GST settings in Amazon are correct, and avoid paying more than you need to.

GST in New Zealand is a 15% tax added to the price of most goods and services – including most goods imported by foreign sellers.

Brad Golchin, managing director of Wise Advice, has one piece of advice: get to know the jurisdictions you’re selling in, or find someone who does.

Also, a trick for ecommerce businesses operating internationally – keep local currency for all the jurisdictions you’re likely to owe tax in.

Key Takeaways for Ecommerce Sales Tax

  • Don’t skimp on or skip sales tax. Ecommerce sellers are under the microscope now more than ever.
  • The “Wayfair decision” was pivotal in ecommerce sales tax regulations, and states are coming after sellers who do not comply.
  • Each state has different rules about whether you need to pay tax and how much.
  • The best place to start is by figuring out which states consider you to have nexus with them. 
  • Make sure that you register for sales tax in these states and get a permit before you start collecting sales tax.
  • Remember that if your marketplace facilitator collects tax for you, you still need to remit the tax.
  • Remember that if your marketplace facilitator doesn’t collect tax for you, but you have nexus in a state, you need to collect the tax yourself.
