Sales Tax

Sales tax is a percentage-based tax added to the price of a product or service at the point of sale, collected by the seller on behalf of a government and later remitted to the relevant tax authority.

Sales tax rules vary by country and, within some countries, by state, province, or local jurisdiction. In the United States, obligations are set at the state level and often depend on whether a seller has nexus, a legal connection to that state created by physical presence or sales volume.

Many other countries instead use value-added tax, applied at multiple stages of production rather than only at final sale. For dropshipping and ecommerce sellers, this means obligations can differ for every region a store sells into, separate from how a payment gateway processes the underlying payment.

Sales tax is a legal and financial obligation, not a feature a store chooses to enable, which sets it apart from optional pricing tools like multi-currency display.

Key characteristics

• Jurisdiction-dependent rates: The applicable rate depends on the buyer’s location, the seller’s location, or both, and can change between neighboring regions.
• Nexus-based obligation: In many systems, a seller only must collect sales tax in a jurisdiction once a legal connection, or nexus, is established there.
• Collected, not kept: The seller collects sales tax from the customer but does not retain it; the amount is remitted to the tax authority on a regular filing schedule.
• Platform-assisted calculation: Many ecommerce platforms and tax tools calculate the correct rate automatically based on the shipping address at checkout.

Example

A dropshipping store based in Texas sells a phone accessory for 20 dollars. A customer also located in Texas completes the purchase, and the store automatically adds the applicable Texas sales tax to the order total at checkout. The store owner collects that tax along with the payment, then later reports and remits it to the state tax authority during a periodic filing. A customer ordering the same product from a country with no equivalent requirement would not see this charge added.

• Payment gateway – the service that processes the total charge, including any sales tax added.
• Multi-currency – a separate store feature for pricing, distinct from a jurisdiction’s tax requirements.
• Business plan – a planning document that should account for tax compliance costs and obligations.

Frequently asked questions

Do all online stores need to collect sales tax?

Not all online stores need to collect sales tax; the requirement depends on factors like the seller’s location, the buyer’s location, and whether the seller has established a legal connection, or nexus, to a taxing jurisdiction. Requirements vary widely between countries and, within the United States, between states.

How is sales tax different from value-added tax?

Sales tax is typically collected only at the final point of sale, while value-added tax is collected at multiple stages of production and distribution. Many countries outside the United States use value-added tax instead of, or alongside, traditional sales tax.

Who is responsible for remitting sales tax to the government?

The seller is generally responsible for collecting sales tax from the customer and remitting it to the appropriate tax authority on a set filing schedule. Some ecommerce platforms or marketplaces may handle this calculation and remittance automatically on behalf of the seller.

Does sales tax apply the same way to dropshipped products?

Sales tax generally applies to dropshipped products the same way it applies to any retail sale, based on customer location and the seller’s tax obligations there. Some jurisdictions add rules involving the supplier’s location, so sellers should confirm requirements for their specific setup.

What creates a sales tax obligation in a new state or region?

In the United States, a common nexus threshold is around 100,000 dollars in annual sales into a state, historically paired with a 200-transaction test, though several states have dropped the transaction rule. Crossing the applicable threshold can create a new collection obligation, and exact figures still vary by jurisdiction.
