"Best service I have signed up for! My life has changed because of the team as tax jar. I no longer have to spend days preparing my sales tax returns. I have more time now to grow and have expanded to other countries. Seriously, if you want to save two to three days time per month and not have to do number crunching and data entry sign up. It was the best move I made."

Common Questions

Feel free to contact us if you can't find the answer to your question. We're happy to help you.

I've heard good things about TaxJar, how will it help me and my business?

TaxJar's automated reports eliminate the need for you to lookup sales and sales tax information by state, county, city, and local tax jurisdiction. We give the the exact data you need to be able to file your tax returns much faster than using Excel spreadsheets.

For many states we'll even file your sales tax returns for you. Our reports are updated every day and downloadable in CSV format. You'll also receive email reminders when your sales tax returns are due. Lastly, you'll be able to see what sales tax you should have collected using our detailed sales tax analysis feature.

I'm new to Amazon. What do I have to do to get started in sales tax?

We created an entire website called FBASalesTax.com to help new Amazon sellers figure out how to become sales tax compliant.

Does TaxJar work with individual Amazon accounts?

According to Amazon, to be eligible to connect TaxJar to Amazon, sellers must have at least one of the following:

  • Non-individual selling on Amazon account
  • Amazon Webstore account
  • Checkout by Amazon account
  • Amazon Product Ads account

Sellers with only individual selling on Amazon accounts are not eligible to register for or use MWS. If you are an individual seller and would like to use MWS, you can become eligible to register for MWS by upgrading to a Pro Merchant seller account from the Amazon Services Selling on Amazon page.

Can TaxJar file my sales tax returns automatically for me?

Yes. With AutoFile you can file sales tax returns in most states. Learn more about AutoFile.

Can TaxJar determine how much sales tax should have been collected?

We sure can! This feature can be very helpful if:

  1. You aren't sure if you’ve set up your sales tax collection correctly.
  2. You have sales before you started collecting sales tax.
  3. You sell on multiple channels, but aren’t collecting sales tax in all of them.
  4. You use Fulfillment By Amazon, but aren’t collecting sales tax in some of Amazon's warehouse states.

As an FBA seller, does inventory give me nexus in other states?

Yes. No matter how much revenue your business is generating, sending your inventory to FBA turns your business from one that collects and pays sales tax in a single state to one that could potentially have to do the same in more than a dozen states. Here's why – all states that have FBA warehouses say that your inventory counts as nexus to their state. Nexus means that your business has a presence in a state that is significant enough to do the following three things:

  • Register for a sales tax license in that state.
  • Collect sales tax on taxable items shipped to customers in that state (regardless of where the item originates).
  • Remit (or pay) sales tax to the state when they to you to (states usually dictate payment frequency).

After connecting your Amazon account to TaxJar, we automatically tell you which FBA warehouses you're shipping from.
