- Short answer
- Shopify's help names Avalara Tax Compliance and Vertex; a US Shopify page adds Drinks.com. No page we read in Oct 2026 calls TaxJar a replacement.
- Their listings
- TaxJar, Quaderno and Stripe Tax describe their own jobs; none says it replaces Shopify Tax
- One or the other
- A tax app or Shopify's built-in tax service per store, not both at the same time
- Still in Shopify
- Tax-inclusive pricing, taxable flags, and duties and import taxes at checkout stay active
- Cost
- Shopify adds no cost for integrating Avalara or Vertex; for pricing, Shopify's help sends you to the vendor
- No backup rates
- If the app is temporarily unavailable and you have no backup rates set up, no tax is charged on purchases
- Switching back
- Your Shopify settings return at once; if that means Shopify Tax past the billing threshold, its fees start immediately
Which tax apps does Shopify itself name?
Shopify's Help Center gives its own pages to exactly two tax apps, Avalara Tax Compliance and Vertex, and its Tax Platform page names the same two partners, adding “More partners coming soon.” Tax apps calculate tax “in all countries and regions”, so they are also the route for destinations Shopify Tax doesn't cover. The US Shopify Tax page also names Drinks.com: with Vertex, Avalara or Drinks.com, the third-party service manages tax calculation and Shopify Tax is automatically disabled.
The Tax Platform partner list is short by design: Shopify's Tax Platform is available by invitation only to select tax software companies. No Shopify page we read in October 2026 — the Help Center tax pages, the Tax Platform page, the US Shopify Tax page and shopify.dev — publishes a full list of the tax apps your admin offers.
Avalara and Vertex are both paid and need a direct contract with the vendor; Shopify adds no cost for integrating Avalara or Vertex; for pricing and functionality, Shopify's help sends you to the vendor.
Searching for AvaTax? That legacy app was deprecated on May 1, 2025 for merchants collecting US sales tax; the name Shopify uses now is Avalara Tax Compliance.
On the Shopify Plus or Shopify Enterprise Commerce plan, with at least two business entities set up with Shopify Payments, each assigned to its market, and all shops migrated to new Markets, a single Avalara connection can serve all your entities.
What about TaxJar, Quaderno and Stripe Tax?
| App | Who describes it | What that source says it does |
|---|---|---|
| Avalara Tax Compliance | Shopify: Help Center, Tax Platform page | Paid tax software, added as a tax app |
| Vertex | Shopify: Help Center, Tax Platform page | Paid tax solution, among Shopify's tax apps |
| TaxJar | The vendor's own listing | Automating sales tax calculations and filing; Stripe-owned since 2021 |
| Quaderno | The vendor's own listing | Registrations, global tax filing and mandatory e-invoicing |
| Stripe Tax | The vendor's own listing | Monitoring where you need to collect through automated filings; imports Shopify transactions to Stripe |
| Avalara's Shopify Extractor and marketplace extractor | The vendor's own listing | Import transactions into Avalara for Avalara Returns filing |
Help Center pages, Shopify's Tax Platform page and App Store listings read October 17, 2026 — a dated snapshot, not every tax app.
An App Store listing is not the same as a tax app that replaces Shopify Tax's calculation. No Shopify page we checked in October 2026 — the Help Center tax pages, the Tax Platform page, the US Shopify Tax page and both Shopify changelogs — names TaxJar, Quaderno or Stripe Tax as one, and their listings describe the jobs above without saying they replace Shopify Tax.
The US Shopify Tax page says, without naming which ones, that third-party services available on the Shopify App Store that manage registration and tax filing can integrate with Shopify Tax.
Before you sign, look for the app under Settings > Taxes and duties > Manage tax service — that is where Shopify has you find and install one. In our development store on October 18, 2026, that list held just two, Avalara Tax Compliance and Vertex Tax & Compliance, both marked Paid app. If it isn't there, ask the vendor how it connects.
What changes when a tax app replaces Shopify Tax?
An active tax app replaces Shopify's tax service for that store and most of your admin's tax settings. The rule:
You can use either a third‑party tax app or Shopify’s built‑in tax service for a store, but not both at the same time.
These settings stay active in Shopify while an app calculates tax:
- Tax-inclusive pricing
- Tax-inclusive pricing by country
- Products marked as taxable
- Customers marked as not taxable
- Duties and import taxes collected at checkout
Before you activate one, you need an account with the tax provider and a complete shipping origin address. Support comes from the vendor: tax apps are made by third parties and aren't managed by Shopify.
If you sell B2B, a company's saved tax information goes to the provider to calculate exemptions. Historical orders you import also sync with the app by default.
How do you switch to a tax app, and back?
Switching takes two stages: find the app on the tax service page, click Install and connect it to your account with the provider; then configure your tax settings in the provider's system and click Activate on the banner in Taxes and duties. Until you complete the activation steps, your existing tax settings keep collecting tax.

- Taxes and duties
- Manage tax service
Shopify's help calls this list the Tax apps section; in our development store it is headed Apps.
Deactivating or uninstalling an active app immediately reverts tax calculation to your Shopify settings. If your previous US tax service was Basic Tax, your settings return to Shopify Tax instead. Whenever your settings revert to Shopify Tax and your store is past the billing threshold, Shopify Tax fees on orders where tax is calculated start immediately.
In the US, Shopify Tax's automated filing isn't available if you used another tax service in 2025, such as a third-party tax app. Automated filing itself is ending: for stores already enrolled, it files returns for sales made through December 31, 2026, and in New York also the full December 2026–February 2027 quarterly return.
