While running an eCommerce business, regardless of your domicile status, you face multifaceted challenges that the US tax system imposes. A patchwork of 50 states with different tax rates based on the state sales tax laws complicates the task of staying tax-compliant.

An eye-opener: There are about 11,000 different authorities that impose a sales tax in the United States.

As more and more sellers were gaining online presence, tax jurisdictions reconsidered their requirements for online entrepreneurs. Adding some new sales tax laws, such as the tax nexus Wayfair ruling, made tax categorization more complex. And with that, try to picture how dealing with VAT rules can make things even worse when it comes to selling internationally. 

With their heads twice the size, online entrepreneurs generally get swamped by a screed of sheet reports and tedious sales tax calculations. And this is where sales tax automation software makes the case. The trickiest thing is to choose the one that can:

  • provide well-versed and up-to-date tax advice and sales tax compliance services

  • minimize the risk of tax reporting errors which can ruin customer trust and trigger even more severe tax compliance problems

Can Avalara AvaTax Ease My Sales Tax Headaches?

Short answer is yes!

Here are at least four clear benefits for you if your eCommerce platform is integrated with the Avalara AvaTax plugin.

1. Streamline Your Tax Calculations and Returns

Avalara tax automation software calculates tax rates, validates the customer’s address information, and automatically inputs the results into your shopping cart or invoice at the time of purchase. 

Integrated with your eCommerce platform, AvaTax also manages the heavy lifting of the filing procedure, thereby saving you the pains of filling out the immense amount of information by hand.

2. Stay Tax Compliant

With all the shiftiness and multiformity of the US economic nexus laws, even a seasoned online seller doesn’t feel entirely at ease with tax determination and reporting. As a result, some eCommerce businesses find themselves unintentionally non-compliant, which may lead to severe tax audit penalties. 

Luckily, there is a way to avoid tax sanctions and keep tax compliance under control by utilizing an automated AvaTax sales tax tool.

3. Improve Taxing Accuracy

While inaccurate sales tax calculations impose serious risk for your business credibility, AvaTax service provides highly accurate product taxability assessments. It significantly reduces the possibility of human error, thereby delivering a better customer experience and contributing to the number of positive reviews.  

On top of that, AvaTax generates detailed real-time reports on-demand and allows the export of data for transactional tax filing.

4. Benefit from Streamlined Sales Tax Program

Because of the currently implemented tax nexus laws, enrolling in a Streamlined Sales Tax program has become critical for eCommerce businesses with economic tax nexus in multiple states. Let’s first figure out what an SST Program is if you are still unaware for whatever reason.

A shortcut:

Streamlined Sales Tax (SST) is a program designed to make sales tax compliance easier and more affordable. 

How does it work? 

The US states which participate in the SST program offer simplified tax registration requirements and more uniform rules for calculating taxes and filing returns. On top of that, they offset the cost of your automated sales tax solution provided that you are using a certified service provider (CSP), like Avalara.  

Current SST states:

Arkansas, Georgia, Indiana, Iowa, Kansas, Kentucky, Michigan, Minnesota, Nebraska, Nevada, New Jersey, North Carolina, North Dakota, Ohio, Oklahoma, Pennsylvania, Rhode Island, South Dakota, Tennessee, Utah, Vermont, Washington, West Virginia, Wisconsin, Wyoming
