Odoo Taxjar Connector FAQs

These frequently asked questions cover the most common setup, daily use and troubleshooting topics for the Odoo Taxjar Connector. For help options, see Odoo Taxjar Connector Support Policy.

Getting Started

Which Odoo editions does the connector work with?

The connector works with Odoo Enterprise, Odoo Community and Odoo.sh.

What does the connector do?

When you create a quotation or an invoice, the connector gets the correct US sales tax from TaxJar and applies it. The tax depends on where you ship from and where your customer is. When you validate an invoice, the connector sends it to TaxJar, so your tax reports and return filing are ready.

What do I need from TaxJar?

You only need your TaxJar API token. Copy it from your TaxJar dashboard and paste it into the API Token field of your TaxJar account in Odoo.

Can I use the connector if my company is not in the United States?

No. A TaxJar account only works with a company whose country is the United States. If the company country is different, the app shows “Please check your company country!”.

Can I test the connector before going live?

Yes. The TaxJar account has an Environment setting. Set it to production only when your credentials are certified for production.

Setup

How do I connect my TaxJar account to Odoo?

1. Go to Invoicing ‣ Configuration ‣ Taxjar ‣ TaxJar Account and create a new account.

2. Paste your token in the API Token field.

3. Click Confirm.

Confirming tests the connection and activates the account. Your states with nexus are imported and shown on the Your States with Nexus tab.

How do I import the TaxJar product tax categories?

Open your TaxJar account and click Sync Category. The categories appear in Invoicing ‣ Configuration ‣ Taxjar ‣ TaxJar Category, each with its Tax Code and Description.

How do I tag my products with a TaxJar category?

Set the TaxJar Category field on a product. To cover many products at once, set the Taxjar Category field on a product category instead.

How do I make orders use TaxJar taxes?

Attach the TaxJar account to a fiscal position with the TaxJar Account field. From then on, orders that use this fiscal position get TaxJar taxes.

How do I update my nexus states?

Open your TaxJar account and click Sync State. To cover all US states instead, check Export All US State Transactions?. Then the app calculates taxes for quotations and invoices and exports all USA customer invoices to TaxJar.

How often are tax rates refreshed?

You choose. On the TaxJar account, set Refresh Rate Interval and Interval Unit. The unit can be Minutes, Hours, Days, Weeks or Months.

Can I split the tax into city, state and county lines?

Yes. Check Apply Tax Breakdown on the TaxJar account. The tax is then split into lines, such as city, state and county taxes. Leave it unchecked to show one combined tax.

How do I decide how taxes are named?

Go to Invoicing ‣ Configuration ‣ Taxjar ‣ Tax Format and create a format. On the Lines tab, add lines with a Sequence, a Type, and an optional Prefix and Suffix. The Type can be Hardcoded, State Name, State Code, Country Name, Country Code, City, County, ZIP Code, Percentage or Add a space.

Select a contact with an address in Address to see a proper Preview. Click Sync County to fetch the county from TaxJar. Use Tax Group to set the default tax group for new taxes.

Then pick your formats on the TaxJar account. With Apply Tax Breakdown unchecked, set Tax Format. With it checked, set City, State, County and Special, one for each tax level.

Which accounts are used on new taxes?

On the TaxJar account, set Default Invoice Tax Account and Default Credit Note Tax Account. The connector uses them when it creates a new tax.

How do I turn on automatic invoice sync?

Check Transaction Sync? on the TaxJar account. Invoices and refunds are then exported from Odoo to TaxJar automatically.

Who is told when an export fails?

Select users in Activity Assigned To on the TaxJar account. If an error occurs at export time, an activity is created and assigned to them.

How do I turn on address validation?

Check Allow Address Validation with TaxJar on your company. You can then validate customer addresses from the contact form.

Daily Use

Do I need to do anything to get taxes on quotations and invoices?

No. The right sales tax appears on quotations and invoices when you add a product. Make sure your warehouse and customer addresses are complete, because tax depends on both.

What happens when I validate or cancel an invoice?

With Transaction Sync? checked, a validated invoice or refund is sent to TaxJar. If you cancel it, it is removed from TaxJar. The Is sync with TaxJar field on the invoice shows whether it is synced.

How do I send past invoices to TaxJar?

1. Open your TaxJar account and click Backfill Transactions.

2. Set the From Date and To Date.

3. Click Export.

How do I handle tax-exempt customers?

Set the TaxJar Exempt Type on the customer. It is used when the app calculates order taxes and uploads invoices to TaxJar for this customer. Click Apply to Child Contacts to copy it to the customer’s child contacts.

What is an exemption mismatch?

A customer and their delivery address can have different exemption settings. Then the Is Exemption Mismatch field is set on the sales order or invoice. Click Correct Exempt Type on the sales order, or Correct Exemption Type on the invoice, to fix it.

How do I validate a customer address?

1. Open the contact and click Validate(TaxJar).

2. Compare the current address with the Taxjar Verified Addresses.

3. Click Save to use the verified address, or Cancel to keep yours.

Where can I see the tax rates the connector uses?

Go to Invoicing ‣ Configuration ‣ Taxjar ‣ TaxJar Rates. Each rate shows the address details, such as From Zip, To Zip, From State and From Country, the City Tax Rate(%), State Tax Rate(%), County Tax Rate(%) and Special Tax Rate(%), and the Last Sync Date.

Why does an order line show a Taxable Amount(TaxJar)?

For some product categories, only part of the line is taxable. TaxJar sends this value based on the customer address and the TaxJar product category. It appears in Taxable Amount(TaxJar) when it is less than the subtotal.

Troubleshooting

I get "TaxJar API token is empty!" or "Unauthorized API Token!!"

The API Token on your TaxJar account is empty or not accepted by TaxJar. Copy the token again from your TaxJar dashboard, paste it into API Token, and click Confirm.

Also check the Environment button at the top of the account. It must match your token: Production for a live token, Test for a sandbox token. Click the button to switch, then click Confirm again.

I get "Please check your company country!"

TaxJar accounts and TaxJar fiscal positions only work when the company’s country is the United States. Set the company country to the United States and try again.

I get "Taxjar account not found or not confirmed."

This message can appear when you click Sync County on a tax format or Validate(TaxJar) on a contact. It means the company you are working in has no confirmed TaxJar account. Open that company’s TaxJar account and click Confirm.

I get "Please define tax format on TaxJar Account."

One or more tax formats are missing on your TaxJar account. Which ones you need depends on Apply Tax Breakdown:

• Apply Tax Breakdown checked: set City, State, County and Special.

• Apply Tax Breakdown unchecked: set Tax Format.

I get "Invalid percentage lines!"

A tax name format can have only one line with the Percentage type. Remove the extra lines.

I get "Please select an Address with a ZIP code first."

Sync County needs an address with a ZIP code. Select a contact with a ZIP code in Address and try again.

I get "Configuration Error: The 'From Date' cannot be later than the 'To Date'."

In the backfill wizard, the From Date must be on or before the To Date. Fix the dates and click Export again.

I get "Error From TaxJar". Where can I see more?

The text after “Error From TaxJar :” is the reason TaxJar gave. If the error happened when an invoice was sent to TaxJar, the same reason is saved in a TaxJar Export Error activity on the invoice, assigned to the users in Activity Assigned To on your TaxJar account.

Failed requests are not saved in the TaxJar logs. The logs only keep requests that TaxJar accepted. See Where to review API request logging, as applicable?.
