While WooCommerce's customizable storefront makes selling online simple, a 2018 court ruling in South Dakota v. Wayfair introduced challenges to the ecommerce world by allowing states to require sellers to collect sales tax even if the company had no physical location in the state.

If you run a WooCommerce store with $100,000 or more in annual revenue, you're likely to owe sales tax on e-commerce sales in multiple states in the post-Wayfair era, as well as GST or VAT if you sell outside the U.S. Unfortunately, WooCommerce can't help you fulfill your responsibilities in these locations.

Failure to follow tax rules can result in steep penalties of 10% to 25% of back tax plus interest. Audits are common, so compliance is essential.

While WooCommerce can collect sales tax, it does not handle remittance and requires extensive configuring. Solutions like Numeral integrate seamlessly into WooCommerce, ensuring compliance with much less work.

This guide will explain the details of how WooCommerce handles sales tax natively, what the gaps are, and how to best manage sales tax compliance through the WooCommerce platform.

Does WooCommerce collect sales tax?

When you sell products online using certain platforms like Amazon or Etsy, the platform is classified as a marketplace facilitator because it plays an integral role in the transaction. Marketplace facilitators collect the correct amount of tax on your behalf and remit it for you.

WooCommerce, however, is not a marketplace facilitator.

WooCommerce can collect sales tax for you, but manual configuration may be required, including setting tax classes for products and selecting whether to calculate tax based on the shipping address, billing address, or store address.

Unfortunately, tax collection is also a small part of your compliance obligations. Your company must complete other tasks, including tracking when you establish nexus based on sales volume and number of transactions, registering when required, and filing and remitting tax.

You must fill the gaps left by WooCommerce to avoid violating tax laws and putting your company at risk of owing back taxes and penalties.

WooCommerce and sales tax nexus: How it impacts what you need to do

The absence of nexus tracking is one of the biggest gaps in the tax tools offered by WooCommerce. That's because, when Wayfair changed the rules for when states could require companies to collect sales tax, it did so by expanding when companies can establish nexus.

This fundamentally changed the rules for when a state could require a business to collect sales tax, as establishing nexus triggers a requirement to register to collect tax, collect the correct amount, file sales tax forms, and remit tax payments regularly.

What is sales tax nexus?

Sales tax nexus means a company has enough connections with a state that the state is entitled to require the business to register to collect sales tax.

Traditionally, companies only established nexus by having a physical presence. This could include a store, a warehouse, or local employees. In an effort to collect more revenue, some states did have a broad definition of nexus, including things like selling products at trade shows.

Still, the physical nexus requirement was limiting as ecommerce sales grew. States began pushing the envelope to capture more revenue, and eventually, the court heard a challenge to the physical nexus rule in Wayfair and established a new framework called economic nexus.

The court allowed states to impose sales tax obligations on sellers with a major local economic presence, even without a physical location. This meant a business that sold to many local customers was deemed to have enough connections that it had to follow local sales tax rules.

Economic nexus thresholds that affect WooCommerce sellers

Under the Wayfair framework, states had to pass laws that established reasonable thresholds for establishing economic nexus. Each state sets its own rules, but there are some common trends. For example, in many locations, a business establishes economic nexus if:

• It does more than $100,000 in sales to customers within a specific state
• The company enters into more than 200 transactions with in-state customers (many states are phasing out this transaction-based threshold, but it still exists in some jurisdictions)

Ecommerce companies now must track sales and transaction volume in all states where they operate to see if they cross the thresholds. Failure to register when required based on volume and collect sales tax when selling online can result in back taxes, penalties of 10% to 25% of unpaid taxes, interest, and audit exposure.

WooCommerce will not track whether you have crossed the thresholds. Your company must manually monitor the key metrics and respond quickly when nexus is established to register and begin collecting and remitting the required tax.

How to set up sales tax in WooCommerce (step-by-step)

While WooCommerce will not help fulfill all compliance requirements, it will collect tax due—but only if you enable this option and configure your tax settings.

Here are the steps to setting up sales tax collecting in WooCommerce:

1) Enable tax in WooCommerce settings

WooCommerce will not collect sales tax by default unless you enable taxes. You can do so by taking the following steps:

• Open up your WP Admin dashboard
• Navigate to the Settings section of WooCommerce
• Select "General" under settings
• Scroll down to the Taxes and coupons section
• Select "enable tax rates and calculations" (this is a checkbox)
• Save your changes at the bottom of the screen.

2) Configure tax options

The next step is to configure your tax options.

There are many variables when collecting sales tax, and WooCommerce requires you to understand which rules apply to the products or services you're selling so you can correctly configure tax collection.

You'll complete this process by navigating to WooCommerce > Settings > Tax. The options you must configure include:

• Whether to determine the tax rules based on your store's address, or based on the customer's billing or shipping address. This depends on whether the buyer and seller are located in origin-based or destination-based states.
• Whether to charge sales tax on shipping: The rules vary by state, as well as based on factors such as whether shipping is separately stated or combined, or whether buyers have the option to pick up the item to avoid the shipping charge.
• Whether tax should be rounded when calculating tax due for each item or at the subtotal line: Most jurisdictions require line-item level rounding, but some require subtotal rounding.
• Whether you want to display prices inclusive or exclusive of tax, both in the shop and in the shopping cart: Inclusive pricing is more common in consumer markets in the EU and UK, while tax-exclusive pricing is common in the U.S. due to variations in tax rates among states.

While WooCommerce has a guide to common tax scenarios, you must largely determine the correct configurations on your own.

3) Set up tax rates manually (or via CSV)

The next step is to configure the tax rates for your items.

Rates vary depending not just on location, but also by product. Some items, such as food and basic clothing, are often non-taxable, while things like digital products or SaaS are taxable in some states but not others.

Tax classes are found in the Tax Settings screen in subtabs along the top. Default settings include standard, reduced, or zero, but there are more tax classes in some locations. You may add more classes by typing the new class into the Additional tax classes box.

The standard rate applies to most products. A reduced rate is a lower rate charged on certain items, such as energy-saving materials. Zero-rated items can include essentials like food. No tax is charged on zero-rated items, but input VAT can be reclaimed in areas that collect VAT.

Within each class, rate tables define which rates apply to which transactions. Each row in the table includes key information like the rate being applied, the country, state, city, and zip code that the rate applies to, and which rate is the priority one to use when multiple rates could apply.

You can manually add new rates by clicking Insert Row, entering all of the required values, and clicking Save. This may be necessary if there are special tax rules applied to products or services you sell in a particular city, state, or zip code where you do business.

If you don't want to manually configure tax rate tables, you can import them from CSV files. This can save time and make charging the correct tax simpler, provided the imported data is accurate.

However, whether you import a CSV file or manually create rows in rate tables, the information is static. It doesn't change unless you change it. Since rates adjust often, you must continually update the data manually, unless you automate the process with a plugin.

4) Setup the WooCommerce tax plugin (free automated calculation)

WooCommerce offers a free plugin that automates rate calculation for sales made in the United States, Canada, the UK, or the EU. The WooCommerce site allows you to add this automation by clicking Add to store.

The automated plugin connects to WordPress cloud services using a Jetpack/WP.com account. You can enable it by:

• Going to WooCommerce
• Selecting Settings > Tax
• Selecting “Enable automated taxes”
• Clicking Save Changes

After you've enabled the plugin, many configurable sales tax settings are disabled. For example, the plugin automatically sets your store to exclude tax when displaying prices and to calculate tax using the customer's shipping address.

While this plugin eliminates manual configuration of tax rules and rate tables, it doesn't offer features like nexus tracking, registration, or filing and remittance. It can work well for small stores operating in one or two states with minimal compliance obligations, but not for bigger ones.

5) Configure tax on shipping

WooCommerce also requires you to configure whether to charge tax on shipping. You'll set this rule in WooCommerce > Settings > Tax, where you can choose from among four options:

• Setting the shipping tax class based on items in the cart
• Applying the standard rate
• Applying a reduced rate
• Applying a zero rate

The first option usually makes the most sense, as it applies the same tax rate charged on the item to the tax rate charged on the shipping. So, for example, if an item in the cart is taxed at a reduced rate, the shipping is as well. This avoids manual adjustments of shipping tax rules.

However, defaulting to the first option won't always result in the correct tax rate being applied to shipping charges. Rules for tax on shipping vary, and WooCommerce doesn't automatically account for this, so the wrong rules and rates could apply if you don't manually configure them.

How to find and use your WooCommerce sales tax report

When WooCommerce collects taxes for you, it creates a Taxes Report that provides some basic information, including the following.

• A summary of all taxes collected during a specified date range
• Comparison mode to search and add all tax codes
• A search function to filter for transactions involving specific tax codes

The report can be sorted by tax code, rate, total tax, order tax, shipping tax, and number of orders:

While the report provides insight into sales volume and the number of transactions, it does not provide key details, including which orders crossed the economic nexus threshold, and it does not allow you to sort by state jurisdiction. This makes its utility limited for nexus tracking.

Where to find the WooCommerce tax report

The WooCommerce tax report can be found by navigating to Analytics > Taxes in your WordPress dashboard:

It can be exported via a CSV download.

What the built-in report includes (and what it's missing)

Here are the details on what you can expect from the WooCommerce sales tax report:

Why the WooCommerce tax report isn't enough for filing

The WooCommerce tax report is missing key details that companies need to comply with registration requirements and to file the appropriate sales tax forms. The report falls short because:

• It shows collection, not liability: If you did not collect the correct amount of taxes because of configuration issues, you won't be able to determine this just from reviewing the report. Errors in configuration can remain undetected.
• Doesn't match the format required by state tax authorities: States have specific requirements for how data is presented, and the WooCommerce report does not follow this format or include all the required details. For example, many states require jurisdiction-level breakdowns, while WooCommerce aggregates data differently.
• Doesn't account for customer exemptions: Some customers are exempt from sales tax, including certain resellers or nonprofits. While WooCommerce makes it possible to configure your account to avoid tax on exempt customers, reporting tools don't provide robust exemption tracking.
• No audit trail for exemption certificate: States require companies to retain exemption certificates to prove that they didn't collect sales tax. WooCommerce has no system for uploading and storing exemption certificates, linking them to customers, or creating audit-ready exemption records.
• If you sell on multiple channels, WooCommerce only shows WooCommerce data. If your company has multiple sales channels, tracking nexus becomes more challenging as you must gather and aggregate reports from each one. WooCommerce doesn't offer tools for this, but only shows transactions processed through its platform.

With key data missing, filing required sales tax forms on schedule becomes more time-consuming, difficult, and risky for your business.
