No uploading spreadsheets

TaxJar syncs up with your Amazon account and automatically pulls the information it needs. You don't need to upload or download anything.

Automatically track sales in all FBA states

Right out of the box, TaxJar will tell you what you might owe in each of the states with an Amazon warehouse. This is important because you likely owe sales tax in these states.

Are you collecting enough sales tax?

See a comparison of what you actually collected versus what you should have collected. If you're not collecting at all, we show you what your liability might be in each state.

County and city granularity in reports

No more manually breaking down sales tax collected by counties, cities or districts. For states requiring it, our reports will break this detail down for you. No one else does this!

Multi-channel and multi-state reports

TaxJar reports can accommodate any of the other channels you sell on, too. Your sales tax collected is organized into state-specific reports for easy filing.

Automated sales tax filing

For an additional fee of $19.95 per filing per state, our AutoFile feature will file your state sales tax return for you every month, quarter or year. Never bother with sales tax again.

Swagasaurus Rex - October 4th, 2016
"Taxjar is a must have for FBA Sellers. I was overpaying sales tax by about 500% because I didn't understand sales tax (at all really!). Taxjar makes it simple to figure out what you owe, and puts you at ease by illustrating clear transaction data. HONESTLY just install it, if you don't love it just remove it... will only take you 10 minutes and you won't look back!"

They have guides that teach you, and running my business with Tax Jar has been simple and very user friendly. I have never filed tax myself and with Tax Jar it's no stress. Also, very quick to respond to your questions, along with great customer service."

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 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. For more info, go to this page.

Can TaxJar file my sales tax returns automatically for me?

Yes. We can automatically file your returns for you in nearly all states with sales tax. AutoFile is an additional cost of $19.95 per filing per state.

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.
