Tax collection and calculation can be a complex and overwhelming process for Amazon sellers like you. It’s especially challenging if you are operating across international borders, between the US and Canada. You surely have wondered, "How is tax calculated on Amazon?"

Let us answer that question and provide you with a comprehensive overview of how taxes are calculated on Amazon for transacting between the US and Canada. From explaining the different types of taxes imposed by both countries to outlining the necessary steps for tax collection, this guide will equip you with the knowledge and tools to navigate the tax landscape on Amazon effortlessly and efficiently.

How Does Amazon Calculate Its Tax?

Amazon calculates its tax based on the applicable tax laws and regulations of the jurisdictions where it operates, taking into account factors such as sales, income, and other taxable criteria.

Sales Taxes in the United States

In the United States, tax charges on Amazon orders depend on various factors, such as the type of item or service sold and the shipping destination or origin. Each state has its own set of sales and use tax rates that need to be considered when calculating taxes on transactions.

US Sales Tax Nexus and Key Factors in Sales Tax Calculation

There are two main factors affecting sales taxes in the US: tax nexus and the Marketplace Facilitator Laws (MPF). Let us know what these two mean for your business.

Nexus

A nexus is a legal term used to describe a significant presence in a state. It can be based on several factors, such as the location of your offices, employees, warehouses, or fulfillment centers. If your business has a nexus in a state where it sells products, you must collect and remit sales taxes for that state.

MPF

You can skip the hassle of collecting and remitting sales taxes on Amazon as the MPF mandates the e-commerce giant do this. Nevertheless, Amazon does not cover local sales taxes not listed on the MPF. In these cases, you have to collect and remit them yourself.

Steps to Calculate US Sales Tax on Amazon

To make your US sales tax calculation and compliance on the platform easier, here are some steps you can follow.

The five steps in calculating sales tax in US

1. Determine Business Nexus.

Identify if you have a sales tax nexus in the states where you sell your products. This includes evaluating if you have a physical presence or economic nexus.

2. Register for a Sales Tax Permit.

Remember that it's illegal to collect Amazon sales tax without a permit, so make sure to register at the state's revenue department.

3. Set up an Amazon Seller Account for Sales Tax Calculation.

In your Amazon Seller Central account, set up your sales tax settings. Input the states where you need to collect sales tax, and assign product tax codes to your items to ensure the correct tax rates are applied.

4. Begin Collecting Sales Tax On The Platform For Amazon To Remit.

Once your tax settings are configured, Amazon will automatically collect the appropriate sales tax based on the applicable tax rates for each state. Amazon will be responsible for remitting collected sales tax to the relevant tax authorities.

5. Utilize Automated Sales Tax Tools.

Consider using automated sales tax tools to help you in tracking, sales tax reporting, and filing your sales tax return. These tools can minimize human errors, save time, and help you comply with ever-changing sales tax laws.

Sales Tax in Canada

Sales tax in Canada includes the different provincial taxes. With different rates applied to individual provinces, you must know the specific tax breakdown. Taxes include the Goods and Services Tax (GST), Provincial Sales Tax (PST), Harmonized Sales Tax (HST), and Quebec Sales Tax (QST). Each of which is determined by the selling price and shipping destination unless stated otherwise.

Key Factors in Canada Sales Tax Calculation

There are three main types of sales taxes in Canada. Each province and territory has its own PST rate and rules. Some locations have combined GST and PST into an HST. 

Goods and Services Tax

The GST rate is 5%, and it is applied to most goods and services sold in the country. The collected taxes are used to fund public services and programs.

Provincial Sales Tax

PST is a sales tax levied by individual provinces in Canada on the retail sale or lease of most goods and some services. 

Harmonized Sales Tax

HST, on the other hand, is a combined federal and provincial sales tax that applies in provinces that have chosen to harmonize their sales tax with the federal GST. HST rates can be up to 15%.

Steps to Calculate Canada Sales Tax on Amazon

To ensure compliance with Canadian tax laws, follow these steps:

The five Steps in Calculating Sales Tax in Canada

1. Register for GST/HST.

To collect and remit sales taxes, register to the Canada Revenue Agency (CRA), especially if your annual sales meet or exceed CAD 30,000.

2. Understand Provincial Sales Tax.

Research the tax rates and rules for each location where you have a nexus to understand the specific PST or HST rates for each province or territory where you have a tax nexus. 

3. Enabling Sales Tax Calculation.

Customize your tax settings in your Amazon Seller Central account to reflect the tax rates and rules of the provinces or territories where you have a nexus.

4. Let Amazon Collect and Remit Sales Tax.

For tax-liable transactions on Amazon, the platform will automatically collect sales tax from customers at the specified rates in your tax settings. Amazon, through the MPF, files sales tax reports, and remits collected taxes to the CRA accordingly.

5. Utilize Sales Tax Software for Accurate Calculations.

To make the sales tax calculation process easier and maintain accuracy, consider using sales tax software. These tools can automatically track tax rates, generate reports, and assist with the filing process if you integrate them into your Amazon Seller Central account.
