Taxcat reads your orders, tells you the day you cross a state's threshold, and prepares every return. Then your own Tax Engineer registers and files for you.
Monitoring is free. $50 per return filed. $100 per state registered.
Hover or tap a state. In the app, each one opens to the date you crossed, the date collection had to start, and what to do next.
Every state measures economic nexus its own way. Taxcat applies each rule to your real order history and keeps watching as orders come in.
Sales and transaction thresholds in 46 states and DC, measured the way each state measures them.
You also get the date you crossed, the date collection had to start, and an estimate of the tax that went uncollected.

A return for every period in every state you are registered in, built from Shopify's own sales records.
The paperwork around the tax, in one place instead of someone's inbox.
Open Taxcat in your Shopify admin. Your order history imports on its own.
Every state on one map, and a prepared return for every period. You can stop here; this part is free.
Click “Register for me” on a state or “File this for me” on a return. One-time setup: your authorization, how the tax gets paid, and access to your state account.
Your Tax Engineer registers or files on the state's site and records the confirmation. You are charged only then.
Every store gets one Tax Engineer: a named member of our team who knows your account, files your returns, and answers when a state sends a letter.
Their photo, email address and phone number are in the app, on your first screen.
Book a 30-minute video or phone call from their open times, shown in your time zone.
Onboarding, a question about a state, a notice that landed on your desk.
Taxcat lives inside Shopify and connects to the other places you sell, the books you keep, and the tools your team already checks.
Shopify orders sync on their own. Sales from other marketplaces come in from their sales reports, so every state threshold counts all of your sales.
When a return is filed, the payment is recorded in your accounting system, so the sales tax you owe on paper always matches what you paid.
New alerts post to a Slack channel. Signed webhooks send filed returns, new registrations and deadlines to any other tool.
Subscribe once and every return due date appears in your calendar, with a reminder three days ahead.
No subscription and no tiers. Charges go on your Shopify bill after a return is filed or a registration is issued, never before.
To file for you we need things you would not hand to just anyone. Here is how they are handled.
State logins, bank details and business details are encrypted with AES-256.
Once saved, a password or account number is never shown back in the app.
A team member has to ask to see a secret, and each time is recorded.
Remove the app and your logins, bank details and business details are deleted.
No. Shopify Tax does that. Taxcat reads the tax Shopify charged on each order and works out where you owe, what to file, and when.
No software files on its own here. Either you file using the return Taxcat prepared, or you click “File this for me” and your Tax Engineer files it on the state's website.
Four things, set up once: approval of billing in Shopify, your business details, a signed authorization, and a way into your state tax account. We recommend adding us as a tax preparer on the state's own site, so you never share your password. Some states also ask you to sign their power-of-attorney form; your Tax Engineer sends it to you.
From your business bank account to the state, when the return is filed. The money never passes through us. You can also choose to pay each state yourself.
International sales are reported by country. VAT and GST thresholds are not monitored.
No. Taxcat applies each state's published rules to your sales and shows its working. For a judgment call about your business, talk to your Tax Engineer or a tax professional.
