It’s Time to Prepare Your E-Commerce Store Sales Tax for Black Friday/Cyber Monday Sales Tax

by TaxJar September 30, 2021


According to statistics from Adobe, shoppers spent 20% more during Cyber Week last year in 2020 than they did in 2019. The pandemic plus expanded ecommerce adoption from brick and mortar retailers partially explain the jump in online holiday shopping. But considering that online Thanksgiving, Black Friday and Cyber Monday sales have increased year-over-year in perpetuity, chances are online holiday shopping will break records again in 2021.

Whether you are one of those brick and mortar store owners who turned to e-commerce due to COVID-19, or have been selling online since early eBay days, one thing you want to double and triple check is that your e-commerce store is set up to collect sales tax before Black Friday and Cyber Monday (BFCM) roll around.

Here’s why.

Sales Tax Can Impact Your Bottom Line

Many online retailers make their entire year’s sales goals during the holiday season. But sales tax can throw a wrench into those gorgeous sales numbers. Collecting too much sales tax from a customer can create a negative experience. But not collecting enough sales tax means that you’re required to pay the uncollected amount out of your profits. Ouch!

To prevent a holiday sales tax disaster, we suggest double checking your sales tax setup on all of your online shopping carts (and if still applicable) marketplaces. Ensure you are collecting sales tax from buyers in all of your nexus states. It can be extremely easy to realize you have nexus in a new state but forget to turn on sales tax collection for that state on one of your sales channels. 

Also, sales tax rates change constantly. If you have any custom sales tax collection set up, it’s time to double check that those rates are still accurate. 

Of course, if you use the TaxJar API to collect sales tax via your online store, then you are all set. TaxJar’s sales tax API is always up to date and ensures you collect the right amount of sales tax from every buyer, every time. 

BFCM Requires Sales Tax Collection that can Scale

Do your sales and marketing teams have some mega-gigantic Black Friday/Cyber Monday promotion planned? Great! Hopefully that means zillions of new customers will pour into your online store and make this your busiest sales day of the year. What could go wrong? 

A stalled or failed sales tax collection engine, for one thing.

Speed is important when your customers are buying online, and every millisecond matters. For example, every 1,000 millisecond or 1 second reduction in page load time for Walmart resulted in a 2% conversion rate increase. Every 100 milliseconds for Mobify resulted in a 1.11% conversion increase. 

A slow checkout can lead your customer to a competitor. Worse, your check out could stall out completely, leaving your customers unable to check out. Nobody wants to see a slew of abandoned carts on Cyber Monday because of an administrative necessity like sales tax. 

TaxJar’s sales tax API clocks in at sub-20ms with 99.99% uptime, which means that your customers instantly see accurate tax data in their checkout view. Our ecommerce sales tax API and calculation engines scale seamlessly, maintaining the same speed and reliability no matter how many transactions are processed at once.

Cyber Week is no Longer Just a Week

Studies show that interest in Black Friday starts to build as early as late October. Or, if your family and friends are anything like mine, if a large appliance starts to go or if a new TV starts to look really good, you’ll tell each other, “Wait for those Black Friday deals.”

Many retailers are getting with the program and offering their Black Friday/Cyber Monday deals earlier and earlier to get a jump on the competition. 

So the time to ensure that you are collecting the right amount of sales tax is now. 

Good News! Marketplace Sellers are Prepared for BFCM

In the US, most ecommerce sellers who sell on marketplaces like Amazon or eBay are in luck in 2021. Every state with a sales tax, with the exception of Missouri, require that online marketplaces collect sales tax on behalf of third party sellers who use their platform. (Missouri has passed a law to require ecommerce marketplaces to collect sales tax, too, but it does not go into effect until January 1, 2023.)

However, don’t confuse an online marketplace with software like Shopify or BigCommerce that allows you to create your own online store. If you sell online via a Shopify store or using a ERP like Acumatica you are still required to collect and remit sales tax in states where your business has sales tax nexus.
