SepticParts.Com  will comply with all State Sales Tax laws in which we have Sales Tax Nexus. SepticParts.Com  will collect and remit sales tax for all states that we ship product to in which we have Sales Tax Nexus.

Items sold on the SepticParts.Com  website and shipped to locations both inside and outside the US, including territories, may be subject to Sales Tax. The amount of tax charged on your order depends on many factors including the following:

  • Whether we have Sales Tax Nexus in your state
  • The type of item or service purchased
  • The time and location of fulfillment
  • The shipment or delivery address of your order

These factors can change between the time you place an order and when your shipment is complete. As a result, the tax calculated on your order may change. We display an “Estimated Tax” to be collected at Check Out when confirming an order. The amounts displayed as estimated tax may then be updated later when your order is finalized and shipped.

If we have Sales Tax Nexus in your state, the tax rate applied to your order will be the combined state and local rates of the address where your order is delivered to or fulfilled from. For example, if you live in a state that does not impose a sales tax, you may still see tax calculated on your order if shipped to another state. Moreover, the tax rates applied to your order may also be different for a variety of reasons, such as a shipment to a residential home versus a business address.

If you are ordering from the SepticParts.Com  website and shipping to a country outside of the US, you may be charged the applicable country tax rate.
