    This guide will take you step by step through how to integrate TaxJar into your Magento 2 account. You’ll learn how to configure Magento 2 to automate sales tax calculations as well as what you need to do when it comes time to file.

    Sales tax is complex, with regulations changing constantly. For a primer on the basics of sales tax, including nexus, registration, filing, reporting, calculations and more, please visit Sales Tax Fundamentals. Also, be sure to take a look at our Resource Center, with articles, webinars and videos for beginners and experts alike.

    Please note that TaxJar for Magento 2 requires a TaxJar Professional or Premium subscription. To sign up, or to upgrade your existing account, please contact our sales team.

    How to Connect Your Magento 2 Store

    To get started, install the Magento 2 sales tax extension. The easiest way is to use the Magento Marketplace and install it from your Magento admin panel.

    Alternatively, you can access all of the code on GitHub and download the extension as a ZIP file by clicking Download ZIP. You can also install our module with Composer using the following command:

    composer require taxjar/module-taxjar

    If you’re installing the extension manually, unzip the archive and upload the files to /app/code/Taxjar/SalesTax. After uploading, run the following Magento CLI commands:

    bin/magento module:enable Taxjar_SalesTax
    bin/magento setup:upgrade
    bin/magento setup:di:compile

    These commands will enable the TaxJar extension, perform necessary database updates, and re-compile your Magento store. If you decide to manually update the TaxJar extension later, run setup:upgrade and setup:di:compile again after installing the update.

    Transitioning from Magento 1 to Magento 2

    Already using TaxJar for Magento 1? Both of our extensions handle sales tax calculations similarly, but if you’ve been using TaxJar for sales tax reporting and filing you’ll need to make a quick change. Log in to your TaxJar account and go to Account > Linked Accounts. Click Unlink to remove your existing Magento 1 connection. In Magento 2, transactions are imported directly through our extension using the TaxJar API. We’ll set up transaction sync shortly.

    Pre-Import Checklist

    Before going further, let’s review some of your existing Magento settings to make sure TaxJar is clear for landing. Log in to your Magento admin panel.

    Go to Stores > Configuration in your admin panel. Under Sales > Shipping Settings > Origin, make sure you have a valid address with a US-based region and 5-digit postal code. If not, go ahead and add your address then click the orange Save Config button.

    Magento Shipping Origin

    If you have existing sales tax rates, don't worry. We only overwrite zip-based sales tax rates if they reside in one of your nexus states. Your other rates will be remain intact and can still be used.

    To review your existing rates, go to Stores > Tax Zones & Rates.

    Magento Tax Rates

    For existing sales tax rules don't sweat it either. We attach our zip-based sales tax rates to new or existing rules based on the tax classes you select in our extension. This means that custom rates can still be tied to existing sales tax rules. We've designed our extension to stay out of the way as much as possible.

    Magento Tax Rules

    Sales Tax Calculations

    You’ve reviewed the pre-import checklist and everything looks ready for primetime.

    Go to Stores > Configuration from the main menu. Select Tax under the Sales configuration menu on the left. We’re now ready to configure the TaxJar Magento 2 extension for sales tax calculations.

    Magento TaxJar Configuration

    Connecting to TaxJar

    Before enabling the TaxJar API, you’ll first need to connect to TaxJar from your Magento store. Click the Connect to TaxJar button. This will open a popup asking you to create a new account or log in to TaxJar. Once you’re in, you’ll be shown a confirmation screen to import your API token:

    TaxJar Connect Confirmation

    Click the Connect button and your token will automatically be saved in Magento. The configuration screen will refresh and show new options:

    TaxJar Configuration After Connection

    Nexus Addresses

    After connecting to TaxJar, you’ll first want to set up the states where your company has nexus. Go to Stores > Nexus Addresses from the main menu. From there you can add, change, or delete nexus addresses associated with your TaxJar account. There’s also a Sync from TaxJar button to automatically import any of your existing addresses from TaxJar:

    Magento Nexus Addresses

    We currently support one address per state/region in the US and Canada. For other countries we support one address per country. Make sure you enter a valid address for each state. If you’re unsure where you need to collect sales tax, read our blog post on nexus. We also provide helpful sales tax guides for each state.

    Once you’re finished adding all of the states where you have nexus, continue on.

    Product Sales Tax Exemptions

    Before enabling the TaxJar API, you may want to assign a TaxJar product tax code to a product tax class in Magento. For example, say you have nexus in New York and sell clothing apparel. Clothing items under $110 are exempt in certain jurisdictions of New York. To set this up in Magento, all we need to do is go to Stores > Product Tax Classes. Click the Taxable Goods class and you’ll notice a shiny new dropdown for assigning a TaxJar product category:

    Magento TaxJar Product Tax Codes

    Select Clothing and click Save Product Tax Class. You now have clothing tax exemptions applied to all products assigned to the Taxable Goods class. This works for new or existing product tax classes. We leave the tax code assigning up to you and it’s completely optional.

    For a list of product tax codes the TaxJar API currently supports, check out our category endpoint reference.

    Customer Sales Tax Exemptions

    To exempt a specific customer in Magento for calculations and reporting, edit the customer and update the TaxJar Exemption Type field with the appropriate exemption type:

    Magento 2 TaxJar Customer Exemptions

    You can also select one or more TaxJar Exempt Regions to exempt the customer in specific regions / states. If no regions are selected, the customer will be exempt everywhere. To exempt multiple customers in bulk, use the customer admin grid to filter your customers and select the customers you’d like to exempt. From there, select an exemption type and click Save Edits:

    Magento 2 TaxJar Bulk Customer Exemptions

    These customers will then be synced to TaxJar. After they’re synced over, they will be exempt from sales tax calculations at checkout and their transactions will be designated as exempt in the TaxJar app for reporting and filing.

    Address Validation

    TaxJar Plus now offers address validation in Magento 2 to help increase the accuracy of sales tax calculations for your store. When tax rates are based on the buyer’s location, a valid shipping address is necessary to ensure the most accurate tax rate. After connecting to TaxJar with a valid Plus account, you’ll be able to enable address validation under Stores > Configuration > Sales > Tax:

    Magento 2 TaxJar Address Validation Setting

    Once enabled, shipping addresses will be validated automatically at checkout and in the customer address book. At checkout, both guests and registered customers will see one or more suggested addresses directly after providing a shipping address:

    Magento 2 TaxJar Address Validation Suggested Addresses

    The address validation feature never blocks or interferes with the checkout process. It asynchronously provides address suggestions after the shipping address is entered. If the shipping address can not be found, the customer is asked to review their address or continue to the next step:

    Magento 2 TaxJar Address Validation Invalid Address

    If the shipping address is fully validated, no suggested addresses are shown to the customer. After a suggested address is selected by the customer, the existing address may be updated on the following step, after a shipping method is selected, or when the order is submitted based on whether you’re using the native Magento checkout process or a 3rd party checkout extension.

    We currently support the following 3rd party checkout extensions for address validation:

    • Aheadworks One Step Checkout
    • Amasty One Step Checkout

    If you use another checkout extension for Magento, please contact us for more information. Feel free to use your own stylesheet and customize the design of our suggested addresses section to better fit your Magento theme.

    Address validation also works on the backend for order creation and customer management:

    Magento 2 TaxJar Address Validation Backend Order

    Enabling the TaxJar API

    By default Magento uses zip-based rates for calculating sales tax. When you calculate taxes by zip code, you may not be collecting the most accurate amount of sales tax. Zip codes can cover multiple districts, counties, cities, and even states/regions. These jurisdictions can have different rates. In addition, you may have product exemptions depending on what you’re selling and where. There’s limitations when you rely solely on a zip code for figuring out sales tax.

    With the TaxJar API enabled you’ll get the most accurate sales tax rates based on the entire shipping address (not just zip code) with built-in support for shipping taxability, sourcing logic, itemized discounts, and product exemptions. Response times are fast (sub-75ms) with 99.99% uptime. Rest assured it won’t interrupt your checkout process.

    TaxJar API Checkout Tax

    Set Enabled for Checkout to Yes for live checkout calculations. Click the orange Save Config button. Upon saving, the TaxJar API will be used for calculations instead of Magento’s rate-based tables. However, we can still use those rate-based tables as a fallback just in case.

    Magento TaxJar API Config

    Backup Sales Tax Rates

    We provide a fallback to Magento’s native zip-based rates in case our API becomes unresponsive. While that’s unlikely to happen, it’s always good to have a backup plan. Upon setting Backup Rates to Yes for the first time, you’ll be shown a screen similar to this:

    Magento TaxJar Import Success

    You’ll notice we imported zip-based sales tax rates for each US state where you have nexus. Since we’re downloading thousands of rates into your database at once, this can take several minutes. For destination-based states, TaxJar always returns the highest rate for each zip code to ensure you’re not under-collecting sales tax. For origin-based states we do the same for wildcard rates. We only provide backup rates for US states at this time.

    If you decide to add a new nexus state under Stores > Nexus Addresses and would like to refresh your rates manually, just click the Sync Backup Rates button. It’s that simple. We’ll automatically refresh your backup rates on the first of each month to make sure they’re up to date.

    To verify sales tax rates and rules are loaded, go to Stores > Tax Rules. You should see your imported rates attached to a couple of sales tax rules:

    Magento Tax Rules

    When turning off nexus for a state, please keep in mind that we never remove tax rates for non-nexus states/regions. This allows our merchants to use their own custom zip-based rates in Magento if needed. After removing a nexus state, you’ll need to manually remove the rates for that state and re-sync your backup rates to refresh the tax rules.

    Backup Sales Tax Classes

    If you’re taking advantage of our backup rates, make sure you select the appropriate product and customer tax classes under the TaxJar configuration. Usually this means you’ll want to select Taxable Goods and Retail Customer if you haven’t added your own custom classes.

    Post-Import Configuration

    After importing zip-based backup rates, TaxJar’s extension automatically does several things to help prepare you for collecting sales tax using Magento’s native calculations:

    Based on your shipping origin state configured under Shipping Settings > Origin, we set Magento's native tax calculations to be based on origin or destination-based sourcing (e.g. your address of shipping origin or the customer's shipping address).

    This means we update a setting under Sales > Tax in your store configuration: Tax Calculation Based On. For most stores, Tax Calculation Based On will be set to Shipping Address. If your store's shipping origin is origin-based (not destination), we'll set it to Shipping Origin.

    Keep in mind this setting only affects Magento's native zip-based rates calculations. If you decide to enable the TaxJar API (live checkout calculations), this will only be used as a backup.

    Our extension sets the following tax display settings under Sales > Tax to Excluding Tax:

    • Price Display Settings
      • Display Product Prices in Catalog
      • Display Shipping Prices
    • Shopping Cart Display Settings
      • Display Prices
      • Display Subtotal
      • Display Shipping Amount

    For most stores, these settings will already be set to Excluding Tax.

    Magento Tax Display Configuration

    If you’re a developer, you may be wondering if TaxJar changes anything with the database after installation. Beyond setting default configuration values and storing extension-related data in the core_config_data table, we only add a single column to tax_class for managing product tax class codes and a tax_nexus table for managing nexus addresses.

    Debug Mode

    If you need to contact support, enabling debug mode shows you diagnostic information about your Magento store and the TaxJar extension itself. It also prevents the extension from downloading zip-based rates into your store.

    Debug mode also allows you to enable the Sandbox environment. TaxJar provides a sandbox environment on all TaxJar Professional or higher plans for automated testing and development. Be careful! The Sandbox environment should only be used for testing and never enabled on a production store.

    To help us help you, take a screenshot of the debug mode message and include it in your support email if you’re having difficulties. Disable it afterwards if you want to continue importing rates.

    Magento TaxJar Debug Mode

    Multi-Store Calculations

    If you have multiple websites or stores with different nexus addresses, you can assign nexus addresses to specific store views. Select the nexus address from Stores > Nexus Addresses and update the Store View dropdown:

    Magento TaxJar Nexus Address Store View

    By default a nexus address will be assigned to “All Store Views” and applied globally. Keep in mind that the same one address restriction applies to nexus addresses at the store level. For example, you can’t add a separate nexus location in California for one of your stores if you already have a global nexus location for California.

    You can also supply different shipping origins per website. Shipping origins are used to help determine sourcing for sales tax calculations. Make sure you review your shipping origins under Stores > Configuration > Sales > Shipping Settings > Origin.

    Sales Tax Reporting

    We’re almost done setting up TaxJar with your Magento 2 store. If you’re interested in sales tax reporting and automated filing, proceed!

    The latest version of our extension now supports real-time transaction syncing between TaxJar and Magento 2. Once your order is invoiced and shipped from the Magento admin panel, it’s automatically synced to TaxJar through our TaxJar API. On subsequent changes, the order is updated. Separate refunds are created for each credit memo in the order. We only sync orders with a complete or closed order state.

    Setting Up Sales Tax Reporting

    To begin syncing transactions with TaxJar, go to Stores > Configuration from the main menu. Select Tax under the Sales configuration menu on the left. Under TaxJar, you’ll find a Transaction Sync setting:

    Magento TaxJar Transaction Sync

    Click the Transaction Sync dropdown and select Yes. If it’s your first time enabling Transaction Sync, you’ll be shown a pop-up window to authorize your TaxJar account for syncing transactions. In order to sync transactions with TaxJar, we require a 30 day reporting trial or paid TaxJar subscription:

    Magento TaxJar Transaction Sync Upsell

    Click the green Enable Transaction Sync button in the pop-up window to finish enabling Transaction Sync in your Magento admin panel:

    Magento TaxJar Transaction Sync Popup

    That’s it! Future orders will now be synced to TaxJar once they transition into a complete or closed order state. To see when a transaction was synced, go to the individual order or credit memo in your admin panel. You’ll find a Synced to TaxJar row in the summary with the sync date:

    Magento TaxJar Order Synced At Date

    You can also browse through your orders and credit memos with the Synced to TaxJar grid column. This is turned off by default, so you’ll need to customize your grid to show it:

    Magento TaxJar Order Synced At Column

    Backfilling Transactions

    Now that we’re syncing transactions, it’s likely that you have previous Magento orders that haven’t been synced to TaxJar yet. To backfill transactions, click the Sync Transactions button that’s shown after you enable Transaction Sync:

    Magento TaxJar Backfill Button

    A modal window will slide in, allowing you to pick a date range of orders you’d like to sync:

    Magento TaxJar Backfill Modal

    After selecting the From and To states, click the orange Sync to TaxJar button. We’ll look for complete and closed orders updated within that date range and push them to TaxJar. Once the process is finished, you’ll be able to view a log of what happened.

    Whenever a transaction is synced to TaxJar, it’s recorded in a log file for your reference. You can find the log file at /var/log/taxjar.log.

    Multi-Store Transaction Sync

    Agencies or merchants with multiple business entities across different websites or stores can now use multiple TaxJar accounts to sync their transactions from a single Magento instance. To get started, go to Stores > Configuration from the main menu. Select Tax under the Sales configuration menu on the left. Switch to one of your stores using the “Store View” dropdown.

    From there, you’ll want to scroll down the page to enable Debug Mode in the TaxJar module. Once the API Token field is visible, replace the existing API token with another TaxJar API token. Click the Save Config button and turn off Debug Mode. Now any order or credit memo processed through that store will be synced to a different TaxJar account for reporting and filing.

    Wrapping Up

    You’ve finished setting up TaxJar and Magento 2! At this point you should be collecting sales tax in your Magento store and syncing orders to TaxJar for reporting. From here on out this guide becomes more in-depth to explain what we’re doing behind the scenes. If you’re curious, feel free to read on.

    How the TaxJar API Works

    Your store seems to be calculating sales tax correctly, but now you might be wondering several things:

    • How many TaxJar API calls will be made per order?
    • What happens if the TaxJar API goes down or becomes unresponsive?
    • How does the TaxJar API handle my custom / international rates?
    • Will the TaxJar API work with my other extensions?
    • How often do the zip-based rates refresh?

    Our extension only makes live API calls when the order resides in a state where you have nexus. This saves you a lot of API calls and money. Additionally, API calls are cached until the checkout data changes. So if you have a customer repeatedly loading the checkout page without changing their shipping info, your store will not make additional API calls. On average, the TaxJar API integration will make 2-3 API calls per order in a nexus state. If you allow customers to estimate their shipping and tax on the cart page, that’s included.

    API calls are only made under 3 circumstances:

    1. Checkout process for a nexus state
    2. Cart shipping and tax estimate for a nexus state
    3. Refreshing zip-based backup rates in the admin panel

    If the order does not reside in a nexus state, the TaxJar API will fall back to Magento’s zip-based rate tables. This gives you the opportunity to use custom or international rates for regions where you may have nexus that TaxJar either doesn’t support yet or you’d rather handle it yourself.

    In the unlikely event that the TaxJar API goes down or times out after 10 seconds, Magento’s native calculations will kick in using the backup rates as well.

    Our TaxJar API integration extends the \Magento\Tax\Model\Sales\Total\Quote\Tax model and overrides Magento’s native calculations only if checkout calculations are enabled. If you’re using a third-party checkout extension or something else that may rely on Magento’s internal rate tables (such as multi-warehouse inventory), try out TaxJar’s extension on a test or staging server before deploying to production.

    Your zip-based rates will refresh automatically on the first of each month via cron job. You can manually refresh these rates yourself by re-saving the TaxJar extension configuration. Each refresh counts as one API call.

    After a customer completes an order using the TaxJar API, our extension will record the sales tax amount and rate by line item in your database. If your store allows multiple currencies, the sales tax will be converted to the customer’s currency:

    Magento TaxJar Alternate Currencies

    How Reporting Works

    After enabling Transaction Sync in your TaxJar extension configuration, we’ll automatically sync orders to your TaxJar account once they’re fully invoiced and shipped. This happens immediately after the order transitions into a complete or closed state using the sales_order_save_after event. Credit memos are synced after the associated order is synced. We support both partial and full refunds in TaxJar.

    Sync requests go through our TaxJar API using the transaction endpoints. Once an order is synced, we save the timestamp in your database to ensure the order is only synced again after it’s updated. In the unlikely event that we can’t sync an order, no timestamp will be shown in the individual order view. You’ll need to backfill the transaction later if you don’t see the timestamp or can’t find the order in TaxJar.

    Transaction API requests and responses are recorded in a custom log file located at /var/log/taxjar.log. This log file contains the sync history for both backfilled and new transactions. You can use taxjar.log for debugging or reaching out to TaxJar support if you experience any issues.

    International Stores

    We support checkout calculations powered by the TaxJar API in more than 30 countries including VAT in the EU and Canada. To perform international calculations, add the countries to your nexus addresses under Stores > Nexus Addresses. For backup zip-based rates, we currently support the United States since it’s tightly integrated with our reporting app.

    With that said, our TaxJar API integration will automatically fall back to custom zip-based rates in Magento and already supports non-USD currencies. If you need backup rates in other countries you can set up custom tax rules under Stores > Tax Rules.

    CLI Commands

    TaxJar now provides a command in the Magento CLI for developers to sync transactions:

    bin/magento taxjar:transactions:sync

    By default this command will backfill the previous day’s updated orders in a complete or closed state. Additionally, you can provide from and to arguments to sync a date range:

    bin/magento taxjar:transactions:sync 01/01/2018 01/31/2018

    We recommend using the CLI for merchants backfilling a high volume of transactions to avoid in-browser AJAX timeouts. You can also use it to increase your PHP memory limit, sleep between date ranges, run the command in a bash script, or schedule the command using a cron job.
