Best Sales Tax Software for Shopify (2026): Top 9 Compared

Shopify Tax is Shopify's native tax service for stores in the United States, Canada, the European Union and the United Kingdom. Shopify's comparison of tax services lists automatic rate calculation from the store's tax registrations and product categories, recommended product categories, rooftop accuracy, support for state fees, tax holidays, advanced tax reports, tax liability insights, and customer and B2B exemptions. In the EU and UK it also generates VAT invoices.

Pricing changed for stores created on or after 13 May 2026. For those stores the $100,000 free threshold is measured across lifetime sales rather than each calendar year. After the threshold, the fee is a percentage of each order where tax is collected, capped at $0.99 per order, and stores with more than $25 million in annual sales are directed to their Customer Success Manager.

The material limit for a growing store is filing. Shopify's help center states that automated filing is closed to new enrollment and applies only to stores already enrolled, which pay $75 per generated return, or $50 on Plus. Shopify Tax decides what to collect; a store that is not enrolled must still register, file and remit through another provider or by hand.

Kintsugi publishes a dedicated Shopify integration page that sets out the division of labour. Shopify calculates and collects tax at checkout; Kintsugi reads orders, products, customers, refunds, POS locations and shop information, classifies products for taxability, tracks economic nexus, and registers, files and remits returns. The page also notes that Shopify's automated filing is closed to new enrollment and excludes imported orders, marketplace sales and amended returns.

The Free plan covers global exposure monitoring, historical liability auditing, automated risk assessment, threshold alerts, AI product categorization, address validation and an in-app assistant. Starter, at $75 per filing or registration, adds automated registration, filing and remittance, deregistration, refunds and amendments, basic exemption certificate management, a virtual mailbox for state notices and onboarding assistance. Premium, priced by quote, adds multi-country compliance, real-time calculation on invoices in ERPs, back filing with voluntary disclosure options, full certificate management, API access and SLA-backed support.

The Shopify App Store listing names Amazon, BigCommerce, QuickBooks, Stripe and WooCommerce among other connections, which matters for stores that also sell outside Shopify.

Numeral sells sales tax compliance as a service rather than a calculation engine. Its Shopify App Store listing is free to install and states the US prices directly: $75 per filing and $150 per registration, with custom pricing for global VAT and GST. The listing also names SST filing and local tax returns among its reporting and filing categories.

The base plan on Numeral's pricing page covers registrations, filing and remittance with autofile and autoregister, a virtual mailbox for tax mail, AI product classification, exemption certificate management, coverage of all US states and jurisdictions, and a concierge service staffed by sales tax specialists. Native integrations are listed with Shopify, Stripe, Amazon and QuickBooks among dozens of others.

The pricing FAQ states there are no setup or onboarding fees for standard US filings, no per-transaction overages, and no required contract. Adding a state costs the $150 registration plus $75 for each return that state requires. A merchant can connect the store and receive a free nexus study before committing, which helps a Shopify brand decide whether it has filing obligations at all.

BreezyFile describes itself as built just for Shopify merchants, and its App Store listing carries the Built for Shopify badge, which Shopify awards to apps meeting its performance, design and integration standards. The listing states that the app works with Shopify Tax: Shopify calculates and collects at checkout, and BreezyFile uses the store's order data to prepare and file returns on time in each US state where the merchant operates.

Features listed are automated filings paid by the due date, state registrations submitted once and then enrolled for future filing, an admin dashboard showing filing history and upcoming returns, and data sync from Shopify orders. The listing's categories include liability calculation, threshold tracking, multi-state filing, SST filing and local tax returns. Support is described as US-based.

Pricing is two figures: $75 per filing and $150 per registration, with the app itself free to install. The listing names Shopify Admin as its only connection. That fits a merchant whose revenue passes entirely through Shopify; a brand also selling on Amazon, at wholesale or through a separate storefront would need to confirm how those sales are reported.

Sidr Tax describes itself as a fully managed US sales tax solution for ecommerce, and its website's main call to action is to install the Shopify app. Its help center explains that autofile uses sales tax reports generated from Shopify transactions and that merchants enroll each state separately. Reports are built from the tax actually collected.

The Free plan covers nexus monitoring across all states, reporting, CSV imports, historical liability analysis, risk assessment, address validation and live chat. Plus adds automated filing and remittance, registration and deregistration, a virtual mailbox for state notices, rooftop-accurate calculations, automatic tax code classification, backfiling and amendments, and notice management. The pricing page lists Colorado home rule filings as included.

The pricing page states that Sidr Tax has removed monthly subscription fees and charges $60 per filing and $150 per state registration. The App Store listing still labels Plus with a $60 monthly figure alongside the same per-filing price, so a merchant should confirm the billing basis before enrolling. The help center adds that state autofile validation can take up to two weeks.

TaxRex is a Shopify app whose website is titled Shopify sales tax automation and filing, and installation runs through the Shopify App Store, where store data syncs automatically. Every plan includes nexus tracking and filing-ready reports; filing and registration are optional services billed when used.

The four monthly plans are set by order volume. Startup costs $10 for up to 200 orders a month with additional orders at $0.05 each and includes state nexus sales reports and an economic nexus analysis report. The $20 plan covers 500 orders and adds multi-store support. The $30 plan covers 1,500 orders and lists an economic nexus analysis dashboard. The $100 plan covers 10,000 orders at $0.01 per extra order.

Autofile costs $25 per return per state and state registration $99 per state on every plan. The free trial lasts 15 days and covers the app and reports; the website states that optional services such as filing and registration are charged immediately. A low-volume store filing in a handful of states will find this one of the cheaper published structures, but should check support levels before relying on it.

TaxCloud is a Streamlined Sales Tax Certified Service Provider and lists a Shopify app in the App Store that is free to install, with nationwide registration and returns filing, SST access, US-based support and 100 orders included. Charges are billed by TaxCloud rather than on the Shopify invoice.

The pricing page sells a subscription chosen by sales platform and order volume, plus a filing tier chosen by the number of returns. Starter includes return-ready reports for all states, SST access, nexus monitoring across all 50 states and email support. Premium adds real-time calculation, ERP integrations, API access and phone support. In the plan comparison Shopify appears as a data import integration, so Shopify Tax continues to calculate at checkout. Returns filing and remittance start at $39 per month, filing plans are described as low as $20 per filing, and audit support starts at $99 per month.

The SST benefit is the main reason a Shopify merchant would consider TaxCloud. The page describes free registration, calculation, filing, remittance, audit support and notice management in 24 SST states. Additional services include state registration, a virtual mailbox and voluntary disclosure support.

AccurateTax is an ecommerce sales tax provider and an SST Certified Service Provider. Its Shopify app, launched in 2024, downloads order information from the store for reporting and offers optional SST integration. The listing describes two ways to use it: complete returns from the app's reports, or have AccurateTax handle filing and remittance as a concierge service. It also lists geolocation of each order to pinpoint the correct jurisdiction.

The free plan covers only filing under the SST CSP contract; other states are excluded. Three Enterprise plans at $50, $90 and $160 per month import 125, 250 or 500 non-SST transactions, and registration or filing in non-SST states costs extra.

The website adds that the company works only on ecommerce sales tax, that rates account for sourcing rules, addresses and product taxability, and that its services extend to exemption certificate management. It charges no setup fee and requires no long-term contract. For a Shopify merchant whose obligations sit largely in SST states, the free plan may cover much of the filing work; a store with significant non-SST exposure should request the per-state filing price.

Zamp positions itself as a fully managed sales tax service and publishes a Shopify integration page. It states that Shopify calculates and collects tax according to the store's settings, while filing and remittance need a separate workflow; Zamp connects to the store, backfills prior orders, refunds and adjustments for nexus analysis, and prepares returns from what was actually collected.

Zamp also lists a free Shopify app, Zamp Sales Tax Dashboard, which breaks down each order's tax by product category and jurisdiction, separates shipping tax and searches by order number. The app shows calculations only; filing comes from Zamp's paid service.

The free plan offers a one-time nexus assessment, historical liability estimate, product taxability review, a 30-minute consultation and an API sandbox. The U.S. plan adds rooftop-accurate calculation, nexus monitoring with alerts at 80% of a threshold, automated registrations, filing with direct ACH remittance and early-filing discount capture, daily portal monitoring, notice handling and specialists who include former state auditors. The U.S. + Canada plan adds Canadian coverage. Neither paid plan shows a price, so cost should be compared through a written quote.
