What is Nexus?

You'll need to collect sales tax in Oklahoma if you have nexus there. There are two main ways that sellers can be tied to a state when it comes to nexus: physical, or economic.

Physical nexus means having enough tangible presence, or activity in a state to merit paying sales tax in that state.

Economic nexus means passing a states' economic threshold, for total revenue, or the number of transactions in that state.

Calculating Nexus in Oklahoma

Physical Nexus

Physical nexus is all about your business having a real, tangible presence in the state. If any of these sound familiar, your business needs to collect and remit sales tax for sales to Oklahoma customers. This could be anything from:
  • An office, warehouse, or a store
  • Employees or sales reps in Oklahoma
  • Storing goods in a warehouse or distribution center
  • Participating in trade shows or other business activities in the state

Economic Nexus

Economic nexus looks at your sales figures. If you hit these numbers in the current or previous year, it's time to register for and collect Oklahoma sales tax. In Oklahoma, you'll have economic nexus if, since September 1, 2018, you have:
  • More than $100,000 in sales in Oklahoma, or
  • 200 separate transactions in the state

Affiliate Nexus

Affiliate nexus comes into play if your business has a connection with another entity in Oklahoma that helps boost your sales. If you're in this boat, you'll need to handle sales tax for Oklahoma customers. This could be:
  • A parent company, subsidiary, or sister company in Oklahoma
  • Affiliates in the state directing customers to you

Click-Through Nexus

Click-through nexus is about online connections. If you partner with Oklahoma-based websites or platforms that send customers your way, and you've made over $10,000 from these referrals in the last 12 months, you've got click-through nexus.

Marketplace Nexus

Marketplace nexus is for those selling through platforms like Amazon, eBay, or Etsy. Since April 10, 2019, these platforms collect and remit sales tax in Oklahoma on behalf of sellers like you.

Steps for Filing a Oklahoma Sales Tax Return

Oklahoma sets your filing frequency based on how much sales tax you collect, and it's pretty straightforward:
  • Monthly Filing: If your business collects over $500 in sales tax each month, you're on a monthly schedule. Your returns and payments are due by the 20th of the month following your sales.
  • Quarterly Filing: Collecting less than $500 but at least $50 a month? Then you're filing quarterly. Your due date is the 20th after the quarter ends.
  • Annual Filing: If your monthly sales tax is under $50, you only need to file once a year, with returns and payments due by January 20th of the following year.

What If a Filing Date Falls on a Weekend or Holiday?

If your filing date falls on a weekend or holiday, the Oklahoma Tax Commission extends your deadline to the next business day. You can check their calendar for specific due date adjustments.
