Online Marketplaces

You do not need to register and collect Oklahoma sales/use tax if two conditions are met: 

• You only make taxable sales in Oklahoma through a marketplace;
• The marketplace facilitator or referrer is collecting and remitting Oklahoma sales/use tax on your behalf, then.

Sales tax payment and filing date

Most of the remote sellers must fill and submit tax returns before the 20th day of the month following the month in which the sale was made.

A seller whose tax liability does not exceed $50 per month can file semi-annual tax returns. Semi-annual sales tax reports are due by July 20th (for the period from January to June) and January 20th (for the period from July to December).

Penalty and interest

Fail to pay delinquent taxes:

• $15 or an amount equal to 10%, but not to exceed $200, of the total amount of tax, penalty, and interest or the actual liability at the date of issuance of the warrant;
• The penalty for late filing of the tax return within 15 days after the tax payment is 10% of the total tax amount.

Oklahoma sales tax holiday

Oklahoma has a sales tax holiday focused on clothing and footwear, happening annually:

• Dates: The tax-free weekend occurs on the first Friday, Saturday, and Sunday of August each year. In 2024, it falls on Friday, August 2nd to Sunday, August 4th.
• Exemption: During this weekend, qualifying clothing and footwear purchases are exempt from state, city, and county sales tax.

Here’s what qualifies for the Oklahoma Tax-Free Weekend:

Clothing and footwear:

• Designed to be worn on or about the human body;
• Sold for less than $100 (price of the single item).

Some key points to remember:

• This tax exemption applies to online and in-store purchases made during the designated weekend.
• Accessories (jewelry, scarves, etc.) and athletic or protective clothing/footwear generally don’t qualify.
• Local sales tax rates may still apply depending on your location within Oklahoma.
