Sales tax is a complicated world. We’ve put together this series to give you the information you need to navigate the complexities of compliance, as well as the solutions offered through sales tax technology. In this chapter, we start at the beginning: what sales tax technology is and how it helps businesses like yours.

What is sales tax automation?

As companies move toward the productivity and responsiveness of digital transformation, they discover cloud-based sales tax technology can automate end-to-end sales tax processes for greater efficiency and improved accuracy.  

These types of programs handle business registration, apply current tax rates for tens of thousands of jurisdictions (over 12,000 in the United States alone), simplify document management, and file returns. And because they integrate with existing ERP, accounting, and business systems, they can be installed with minimal resource allocation or downtime.

The implementation of sales tax technology can be compared to the transformation that occurred not too long ago with payroll. Once upon a time, employee hours were computed and paychecks were distributed manually. But automation dramatically simplified the process, and most companies wouldn’t dream of implementing manual payroll systems. Considering the complexity and legal liabilities of assessing and remitting sales tax for multiple tax authorities, the benefits of automating sales tax can be even more impactful.

Do all businesses need sales tax technology?

Businesses selling a handful of products in one location may be able to keep up with a manual system. It’s a time-consuming process with an increased chance of error, but many small businesses get by without automation, especially those that don’t sell online.

But for anything more complex, automation can save significant time and resources. Rather than continually updating tax rates, monitoring local tax law changes, sifting through questionably stored exemption certificates, and remitting to multiple jurisdictions with different deadlines, sales tax technology automates each step according to the latest information and policies. Selling in multiple tax jurisdictions, expanding product lines, conducting business across borders or in Colorado, or having multiple exempt customers all increase the burden of sales tax management exponentially. Businesses meeting any of these descriptions should evaluate the ROI of an automated system.

It’s important to keep in mind that all industries can be subject to sales tax obligations. Manufacturing, nonprofit, agriculture, software, telecom — businesses in each are responsible for ensuring compliance. And not owing sales tax isn’t necessarily a get-out-of-filing-free card; it’s often just as time-consuming and labor intensive to prove tax isn’t owed as it is to file and remit a standard sales tax return.
