Sales tax compliance starts with one critical step: sales tax registration. Whether you’re launching a new e-commerce store, selling tangible personal property, or expanding into new states, understanding when, where, and how to obtain a sales tax permit is essential. Staying ahead of your obligations ensures your business operates smoothly across every jurisdiction while avoiding penalties.

Managing sales tax registration—especially across multiple states where nexus applies—can feel overwhelming for growing businesses. This guide simplifies each process step and highlights how tools like Kintsugi help businesses maintain accuracy and compliance.

Step 1: Know Where You Need to Register

Before you begin the registration process, determine where you have nexus—the legal connection that requires you to collect and remit sales tax. Nexus comes in two primary forms:

  1. Physical Nexus: A physical presence such as inventory, offices, or remote employees in a state creates an obligation to register. Businesses selling tangible personal property must apply for a sales tax permit in any state where they meet this condition.
  2. Economic Nexus: Many states require registration if businesses exceed revenue or transaction thresholds. For instance, surpassing $100,000 in annual revenue or 200 transactions creates nexus obligations.

The Streamlined Sales Tax Registration System (SSTRS) simplifies multi-state registration by offering centralized access for participating states. Platforms like Kintsugi make it even easier by automating nexus monitoring, ensuring businesses know their obligations without manual tracking.

Step 2: Gather the Right Information for Sales Tax Registration

Once you’ve identified where you need to register, prepare the required information. Each state has its own process, but common details include:

  • Your business name, address, and contact information
  • Employer Identification Number (EIN)
  • Types of products sold (e.g., tangible personal property)
  • Estimated monthly or annual revenue
  • Any relevant licenses needed for your business

For Shopify sellers, Shopify’s U.S. Tax Migration Guide offers a step-by-step overview to ensure proper tax collection setup. Integrating with platforms like Kintsugi can help streamline this process further by automating registration and tax calculations for accuracy.

Step 3: Apply for Your Sales Tax Permit

To collect sales tax legally, you must obtain a sales tax permit in each state where you have nexus. Here’s how to apply:

  1. Visit your state’s Department of Revenue website. For instance, New York businesses can register via the New York State Tax Department.
  2. Complete the registration form with details like your expected revenue and product classification (e.g., tangible personal property).
  3. Pay any application fees and submit the form.

Manually applying for permits across multiple jurisdictions can take time. For businesses registering in multiple states, the SSTRS offers a single registration process for participating states. Alternatively, tools like Kintsugi simplify the process by handling multi-state registrations and ensuring your business remains compliant.

Step 4: Understand Your Filing Responsibilities After Registration

Once your sales tax registration is complete and you have your sales tax permit, you must comply with ongoing filing and remittance requirements. Key considerations include:

  • Filing Schedules: States assign filing frequencies—monthly, quarterly, or annually—based on your revenue. High-volume businesses usually file more frequently.
  • Deadlines: Filing and payment deadlines differ across jurisdictions, so staying organized is critical to avoiding penalties.
  • Zero Returns: Even if you have no taxable sales for a given period, you may still need to file a “zero return” to maintain compliance.

According to the Sales Tax Institute, businesses should monitor filing requirements carefully. Tools like Kintsugi automate the preparation and submission of returns, ensuring all requirements are met and reducing administrative work.

Step 5: Keep Your Registrations Current

As your business grows, your nexus footprint and sales tax registration obligations will change. Here’s how to keep up:

  • Track Revenue: Many states reset economic thresholds annually, so monitoring your revenue helps ensure compliance.
  • Update Permits: If you expand into new states, add new products, or require additional licenses, update your sales tax registration accordingly.
  • Verify Product Taxability: Different states tax products differently. For example, tangible personal property may be taxable in one state but exempt in another.

The SSTRS FAQ emphasizes the importance of maintaining up-to-date information. Platforms like Kintsugi monitor changes in your nexus status, revenue, and filing needs—ensuring your registrations remain accurate across every jurisdiction.
