This guide will take you step by step through how to integrate TaxJar into your Magento account. You’ll learn how to configure Magento 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.
How to Connect Your Magento Store
First install the Magento sales tax extension. The Magento 1 TaxJar Extension is no longer listed in the Magento marketplace (Magento Connect) and we share 3 options for installation in our GitHub ReadMe.
If you’re installing the extension manually, upload all files in the
/app directory to their respective directories.
If you’re already logged in to your Magento admin panel, log out and log back in again for a clean slate.
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 System > Configuration in your admin panel. Under 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.
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 Sales > Tax > Manage Tax Zones & 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.
Sales Tax Calculations
You’ve reviewed the pre-import checklist and everything looks ready for primetime.
Go to System > Configuration from the main menu. Select Tax under the Sales configuration menu on the left. We’re now ready to configure the TaxJar Magento extension for sales tax calculations.
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:
Click the Connect button and your token will automatically be saved in Magento. The configuration screen will refresh and show new options:
After connecting to TaxJar, you’ll first want to set up the states where your company has nexus. Go to Sales > Tax > 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:
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.
When managing your nexus addresses in Magento, all of your changes are automatically synced with TaxJar. 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 Sales > Tax > Product Tax Classes. Click the
Taxable Goods class and you’ll notice a shiny new dropdown for assigning a TaxJar product category:
Clothing and click Save 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
If you have customer groups exempt from sales tax, you’ll need to set their corresponding tax classes to exempt for checkout calculations. Go to Sales > Tax > Customer Tax Classes. Click the customer tax class you’d like to exempt and you’ll notice a dropdown:
Yes and click Save Class. Now any customers associated with that customer tax class will be exempt from the TaxJar API. If you’re still seeing sales tax collected, make sure you’re not collecting for this class using our backup rates feature or your own custom tax rates by reviewing your tax rules under Sales > Tax > Manage Tax Rules.
Enabling TaxJar’s 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 TaxJar’s 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.
Set Enabled for Checkout to
Yes for live checkout calculations. Click the orange Save Config button. Upon saving, TaxJar’s 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.
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:
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 Sales > Tax > 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 Sales > Tax > Manage Tax Rules. You should see your imported rates attached to a couple of sales 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. Additionally you’ll want to select
Shipping for a separate tax rule if you plan to collect sales tax on shipping fees.
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 the shipping taxability and whether to use origin or destination-based sourcing (e.g. your address of shipping origin or the customer's shipping address).
This means we update two settings under Sales > Tax in your store configuration: Tax Class for Shipping and Tax Calculation Based On.
For most stores, Tax Class for Shipping will be set to the default
Shipping product tax class and 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
Keep in mind these settings only affect 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
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
In order to import transactions into your TaxJar account, we need access to your store via Magento's Core API (SOAP/XML-RPC). Our extension automatically creates a new API user and role under System > Web Services. This allows you to automate your sales tax reporting and save hours of time each filing period.
We'll cover how to finish connecting TaxJar to your Magento store shortly. No data will be shared until you link the account from TaxJar, but you now have everything configured to make it work seamlessly. If you'd prefer to only use TaxJar for sales tax calculations, feel free to remove the API user and role.
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.
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.
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.
When debug mode is enabled, calculation API requests and responses will be logged to
/var/log/taxjar/calculations.log. You can use this log file to further investigate issues.
Sales Tax Reporting
We’re almost done setting up TaxJar with your Magento store. If you’re interested in sales tax reporting and automated filing, proceed!
Make sure your server fulfills Magento’s system requirements. Your PHP memory limit should be at least 256 MB or higher (512 MB recommended). If you’re not sure about the requirements, contact your hosting provider.
The latest version of our extension now supports real-time transaction syncing between TaxJar and Magento. Once your order is invoiced and shipped from the Magento admin panel, it’s automatically synced to TaxJar through our 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
closed order state.
Setting Up Sales Tax Reporting
To begin syncing transactions with TaxJar, go to System > Configuration from the main menu. Select Tax under the Sales configuration menu on the left. Under TaxJar Sales Tax Automation, you’ll find a Transaction Sync setting:
Click the Transaction Sync dropdown and select
Yes. That’s it! Future orders will now be synced to TaxJar once they transition into a
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:
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:
You will be redirected to a new page, allowing you to pick a date range of orders you’d like to sync:
After selecting the From and To states, click the orange Sync to TaxJar button. We’ll look for
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
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 System > Configuration from the main menu. Select Tax under the Sales configuration menu on the left. Switch to one of your stores using the “Current Configuration Scope” 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.
You’ve finished setting up TaxJar and Magento! At this point you should be collecting sales tax in your Magento store and importing orders into 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 TaxJar’s API Works
Your store seems to be calculating sales tax correctly, but now you might be wondering several things:
- How many API calls will be made per order?
- What happens if TaxJar’s API goes down or becomes unresponsive?
- How does TaxJar’s API handle my custom / international rates?
- Will TaxJar’s 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, our 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:
- Checkout process for a nexus state
- Cart shipping and tax estimate for a nexus state
- Refreshing zip-based backup rates in the admin panel
If the order does not reside in a nexus state, TaxJar’s 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 our API goes down or times out after 10 seconds, Magento’s native calculations will kick in using the backup rates as well.
Our integration observes the
sales_quote_collect_totals_before checkout event and extends the
Mage_Tax_Model_Sales_Total_Quote_Tax model only if 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:
How Reporting Works
After setting up your Magento connection in the TaxJar app, we’ll automatically queue up an import to pull order and refund transactions from your store for the last 60 days. From there we’ll continue to import your store transactions on a nightly basis. If you sign up for a paid TaxJar subscription, you can request a backfill import for older transactions.
To import transactions from your store into TaxJar, we connect to your store using Magento’s Core API over a SOAP/XML-RPC endpoint. Our extension creates an API user and role automatically.
We break up imports into smaller jobs divided by day to minimize load on your server. To speed up the import process, you’ll want to make sure WSDL Cache is enabled under System > Configuration > Services > Magento Core API > General Settings. WS-I Compliance must also be set to
Orders must be in a
closed state for TaxJar to import them. This ensures we only import completed orders and refunds into the system.
We support checkout calculations in more than 30 countries including VAT in the EU and Canada. To perform international calculations, add the countries to your nexus addresses under Sales > Tax > 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 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 Sales > Tax > Manage Tax Rules.
