Sidr ‑ Sales Tax Automation

I'm so happy I found Sidr Tax. Kevin and Carrie have both been amazing during my onboarding process and put me at ease by walking me through the process at each stage and answering every question I had. I'm looking forward to working with them on an ongoing basis and I couldn't recommend them more.

Very pleased with this app and service. The online chat support is very responsive and helpful, and emails are always answered promptly.

It's a big relief to be able to hand off this monumentally aggravating and time-consuming aspect of my business to experts, for a very reasonable price.

The new flat-fee per-filing pricing is much easier to wrap your head around than the old hybrid system.

I did have a few snags setting things up, and a few shortly after, but the Sidr team addressed everything and got it all taken care of in a reasonable time. Things have been running on auto-pilot since, and it has been a huge relief to not have to deal with sales tax myself any more.

this makes my life so much easier. best app on shopify in my opinion!

Great customer experience!

Sidr is an excellent app for computing and filing required sales tax collected in Shopify. Sidr also makes the Registration of new required States simpler to apply. Their support is excellent and they respond quickly. It has made our collection and filing of taxes so simple. Sidr is also very competitive in the price of service they provide.

Best tax software i have worked with. Support is awesome and gets back to you quickly.

SIDR works well.
Also, their online chat is very good, very helpful.
Better to have the experts work on filing sales tax returns.

Sidr is very prompt and knowledgeable and has done an excellent job handling our Colorado Sales tax filings which was such an impossibly difficult process for me previously! Definitely worth it! So happy with the Shopify integration. It has made life much better!

They don’t just file your sales tax—they become a real support partner for your business. Their team consistently goes above and beyond, offering fast, detailed, and genuinely valuable guidance over chat. The quality of help they provide easily feels like a consulting service, and they deliver it with patience and clarity every time.

Sidr company helped me file my sales tax the same day I reached out. Their team responded very quickly and made the whole process simple and easy to understand. Compared to other services I’ve tried, their pricing is very affordable, and the experience was way smoother. Highly recommend to any store owner looking for fast and reliable tax filing help!
