Ecommerce sales tax is confusing, and it pays to get it right!

The Challenge: Confusing and Costly Sales Tax for Ecommerce

Sales tax compliance is one of the biggest pain points for ecommerce merchants. Rules and rates vary vastly across dozens of states and thousands of local jurisdictions. This creates a maze of obligations and considerations for anyone selling products online. Even cities and counties within the same state can have different rates and requirements.

To make matters worse for online merchants, a 2018 Supreme Court decision (South Dakota v. Wayfair) allows states to enforce economic nexus laws. This means that, even if you have no physical presence, you may be required to collect sales tax in a state if your sales exceed certain thresholds - and even these can be different from one state to another.

There are serious consequences to getting sales tax reporting wrong. If you fail to collect or remit sales tax when required, states can pursue your business for uncollected tax, and levy heavy penalties with interest. It's not just a legal risk: falling behind can lead to stressful audits and unexpected back tax bills that add up quickly. No wonder sales tax management feels overwhelming for many ecommerce merchants!

Online Business Sales Without the Overhead

Many ecommerce businesses believe that a tax automation SaaS tool or a general accountant is taking care of their sales tax needs. However, pre-packaged ecommerce sales tax software solutions do not account for the complexity of home rule states such as Colorado, and most accountants are not trained in their state’s sales tax laws, much less the many varying jurisdictions with their own rates and rules. Failing to prepare accordingly can lead to costly situations.

At Sales Tax Colorado, we are experts in all things sales & use tax, not just in Colorado, but the entire United States. As Shopify partners, we know the limitations of relying on existing software tools, and when to dig deeper in sales tax calculations. Our expertise makes us the right choice for ecommerce merchants in Colorado and beyond.

Ecommerce Sales Tax Nexus Analysis & Monitoring

Nexus Analysis & Monitoring

Not sure where you're supposed to be collecting sales tax? Our team analyzes your sales data and business activity to pinpoint exactly which localities you owe sales tax in. We continually monitor your sales tax nexus status and alert you as you approach the local tax threshold in any state. No more surprises!

State Tax Registrations

State Tax Registrations

Once we have identified where you have nexus obligations, we assist you with registering your business for sales tax permits where required. This process varies from state to state, but we handle the paperwork and filings to get permits in place quickly and in a compliant manner. You'll never have to worry about navigating confusing state tax portals again!

Product Taxability & Exemptions

Product Taxability & Exemptions

Each state taxes products differently. For example, clothing or food might be tax-exempt in one state but not in another, and many goods are taxed at special sales tax rates in some jurisdictions. We assess your product catalog and determine how to tax each item throughout the United States, and assist with exemption certificates when necessary. Offload these time-consuming tasks to a team that handles them every day!

Ecommerce Platform Tax Configuration

Ongoing Ecommerce Sales Tax Compliance

Ongoing Compliance

Sales tax laws and rates are constantly evolving. We keep meticulous records to stay on top of any changes to sales tax compliance throughout the U.S. When a state changes its tax requirements, our team of sales tax professionals adjusts your compliance strategy immediately.

If your business is behind on sales tax compliance, we specialize in cleanup projects. Our team will file past-due or amended returns, correct errors, and work to minimize penalties on taxes you owe.
