Sales Tax Compliance Software for Modern eCommerce

If you have an online store, one of your biggest challenges is undoubtedly remaining sales tax compliant. Whether you primarily sell locally or have a national or international reach, trying to navigate thousands to tens of thousands of sales tax laws across multiple tax jurisdictions is impossible without support.

Enter sales tax software. It’s become essential for ensuring you’re charging the right sales tax to each customer based on their location, types of items purchased, and more. Many types of sales tax software also help with other critical things like keeping track of your progress towards nexus thresholds in different jurisdictions, notifying you when you achieve nexus, handling sales tax registration for you, and even filing and remitting your taxes.

In this post, we’ll break down the best sales tax compliance software options to help you figure out which is best for you.

How does ecommerce sales tax work?

In the U.S., ecommerce companies have been required to collect and remit sales tax since the 2018 South Dakota v. Wayfair decision that found that businesses didn’t have to have a ‘physical presence’ in a state to be required to collect and remit sales taxes in that state.

Since then, companies who have a significant ‘economic presence’ in that state, also known as ‘economic nexus,’ are required to collect and remit sales tax. Each state has different thresholds at which they consider companies to have achieved economic nexus in their state. This is often achieved by doing a certain volume of sales in a state or processing a certain number of orders to that state.

For example, in Connecticut ecommerce companies achieve economic nexus once they make $100,000 in sales and 200 separate transactions in a state in a year.

Once a company achieves sales tax nexus in a state, they must register for a sales tax license and begin collecting, filing, and remitting sales tax. Depending on the size of the company, they could be required to remit sales taxes in a handful of states – or all of them. That’s where ecommerce sales tax software comes in handy.

What is sales tax software?

Sales tax software is any type of software that helps automate aspects of the sales tax management process including tracking nexus, calculating sales tax, collecting sales tax, filing sales tax, remitting sales tax, and helping with sales tax audits.

Not every type of sales tax software helps with all aspects of the sales tax compliance process. For example, some types of sales tax management software will only help with sales tax calculation and collection whereas other types will automate everything for you.

Ecommerce sales tax software integrates with your ecommerce platform(s) to calculate sales tax for you. Generally, it also integrates with your other programs including your ERP, accounting software, and more. This allows you to manage your sales tax compliance in the most efficient way possible.

Choosing a sales tax software

There are a number of different types of sales tax automation software. Which one will be right for your ecommerce business will depend on your needs.

Here are some things to consider before you choose which one’s right for you.

Comprehensive vs. simple: The more features an ecommerce sales tax software has, the more that program tends to cost. However, time is money and so you might appreciate having the entire sales tax compliance process automated for you.

One platform vs. multi-platform: There are a number of single-platform sales tax compliance software plug-ins available for popular ecommerce marketplaces. However, if you sell on multiple platforms they won’t be able to track your sales tax nexus or file your taxes for you without significant work on your behalf to consolidate your sales taxes across platforms. If you sell on multiple platforms, you’re better off getting a sales tax software solution that works across platforms.

One country vs. global: If you sell in just one country, it makes sense to get a sales tax automation software just for that country. However, if you sell cross-border, there are a number of global options. While global software might be more convenient, most charge extra for each jurisdiction so it might be more expensive, in the end, to go with a global software than to choose country-specific options for each of your country’s sites.

Specialized vs. generalized: Some types of sales tax management software are focused on helping niche types of businesses with their sales tax management. For example, there are some sales tax software specifically designed to help SaaS companies.

Real time API vs. basic data integrations: When it comes to how sales tax calculation software calculates your sales tax, there are often two options: a real-time API or a basic data integration. A real-time API makes some additional features possible like geographic address verification and real-time data updates. However, basic data integrations are cheaper.

Premium customer service vs. limited: Like many software options, one of the biggest differentiators between ecommerce sales tax software is the level and quality of the solution’s customer support. Some sales tax software options have very limited customer support whereas others have multiple customer support options and highly responsive support.

What’s right for your company will depend entirely on what your needs are.

Customer review

“Simple tax calculation – Somewhat easy to integrate API if you’re a developer as there is pretty good documentation. As a developer I didn’t totally understand the whole tax VAT collection process going into it. More guides on that would have been helpful as I was getting started. I’m a small business owner and software engineer so more guides on how to not only integrate it but also how to use Quaderno to calculate how much to report and where to report.” – Paul M.

Customer review

“The software does what it is supposed to, it correctly calculates sales tax even on complex transactions. We use the program to calculate tax, store resale and exemption certificates and file our returns in 26 states. The software is not one software and it really shows. If you are storing resale & exemption certificates they goes into one program. Once it is in the system it is transferred to another system.” – Kristin U.

Customer review

“The upsides of Avalara are quite compelling. Firstly, its seamless integrations with different platforms make navigating the complexities of tax compliance remarkably easy for businesses. The user-friendly interface enhances overall efficiency and ensures a smoother experience. The only downside to Avalara so far is the price tag. While the platform nails seamless integrations, the cost might raise an eyebrow for budget-conscious businesses.” – Jordan R.

They also don’t provide audit support.

Customer review
