These clowns just filed AND PAID a seven figure erroneous tax filing for us. The company is a total joke, the support is non-existent, absolutely inexcusable wait times with ZERO accountability from anyone. TaxJar a Stripe owned company, they need to start paying attention to how terrible TaxJar is, it reflects poorly on Stripe.

Extremely disappointing support. Long response times, missed meetings, and our point of contact stopped responding altogether. We couldn't rely on them for our business and decided to move elsewhere.

Do not use this app. Is the worst customer service experience when you need anything from them. In addition to that, if you mark your customer in your store as exempt, Tax Jar won't take this and will file ignoring this. This cause that you'll have to file an amendment with each State and eventually you'll loose money. Don't use this app. it doesn't do the job as expected. Do not use it.

Tax Jar - The juice ain't worth the squeeze. Tax Jar filed incorrect sales & use with the State of New Jersey for us and wanted us to pay Tax Jar again to correct mistakes their app makes. Sounds like a winner right! Taxable and non taxable items in shopify do not line up with Tax jars system. When a sale happens on shopify it goes through Tax jar’s system and you have re-categorize every single sale to ensure non taxable items are not taxed. Nothing like going backwards when busy season is happening to correct these mistakes Tax Jar app makes. This is what happened to us, we had to pay sales tax out of pocket on non taxable items. Now to the real kicker, Tax Jar just doubled their pricing from $19.00 a month to $39.00 a month. So you have a company who’s unwilling to correct their mistakes as well as doubling prices for an app that truly does not simplify your life or work properly.

The app is unusable for any Shopify merchant who has a base currency that is not USD... It assumes USD in the connection to Shopify, which makes the filing completely wrong (they could just read in the USD values from the order, but they didn't think to do such a simple thing). A spoke at length with the support team, who eventually just said they are aware of the shortcoming, but said it wasn't on their roadmap to fix it. So for now, we are doing manual imports to TaxJar which defeats much of the purpose of even using them in the first place. Looking at other reviews of this app, I can see TaxJar are not concerned with building a robust platform that actually works. Very poor service.

*****BEWARE!! DO NOT USE TAXJAR!!! *****Charging us $30,000 in states sales tax when we really owe $300. RIDICULOUS!!! They will not help us amend this before filing. They will be stealing $30,000 from us that we don't have!! They also take days to respond and there are deadlines that they will not help before!

Support can't tell me why the total sales in one county do not equal the sum of sales in three cities located within that county. I'm just getting cut and paste replies that suggest I should inquire with my state's DOR. My return is being flatly rejected because of their faulty calculations. How could the state have an answer for Taxjar's unacceptable numbers? They've basically shrugged their shoulders literally telling me that Taxjar uses 'lots of tax logic'.

Consider this review a serious caution. I wish it were possible to rate this app with zero stars. The support team is virtually non-existent, and on the rare occasion you do receive a response, it's clear they lack any real understanding of their own service. We're currently paying $349 monthly for the Pro plan, which is set to increase to $499 next month. Additionally, they fail to offer SST service as they aren't a certified service provider, which is concerning given the seriousness of sales tax compliance and the risks associated with non-compliance. I strongly advise avoiding this service.
