Best Sales Tax Software for Shopify Stores (2026)
Shopify Tax filing is ending. The best sales tax software for Shopify in 2026: GoodVat, Kintsugi, Zamp, TaxJar, Avalara and Quaderno compared on price.
Shopify calculates tax at checkout, but that’s the easy part. Shopify won’t tell you when you cross a new state’s threshold, won’t register you, and Shopify’s automated filing is closed to new stores and stops after 2026 returns. If you sell in more than one state or country, you need sales tax software alongside it.
We compared seven options on coverage, filing, multichannel support and price.
Disclosure: GoodVat publishes this list. Competitor details come from vendor pricing pages, the Shopify Help Center and the Shopify App Store, checked in October 2026.
The short answer: the best sales tax software for Shopify in 2026 is
- GoodVat: best overall. US sales tax, VAT and GST, every channel, with registration and filing. Free up to 50 transactions/month, then from $20/month.
- Kintsugi: best pay-per-filing option for US stores. $75 per filing.

1. GoodVat: best overall for Shopify
- Best for: Shopify stores selling across states, abroad, or on more than one channel
- Coverage: 140+ countries and 14,000+ US jurisdictions
- Registration and filing: Yes, through local partner tax firms, quoted per country
- Pricing: Free up to 50 transactions/month; $20 (250), $50 (1,000), $100 (2,500)
- Limitation: Registration and filing are quoted per country on top of the plan; setup is sales-led, on a call with the team
GoodVat for Shopify reads every Shopify order and counts it against each US state’s economic nexus threshold and every country’s VAT and GST rules. Add Amazon, Etsy or Stripe and those sales are counted too, so a threshold you cross on two channels combined is still caught.
When you need to register, GoodVat’s partners register you, and they file the returns Shopify no longer will. Pricing is flat, so it doesn’t grow 0.35% at a time with your revenue.
2. Kintsugi: best pay-per-filing option
- Pricing: Free monitoring; $75 per filing, registration or amendment on Starter; custom plans for VAT
- Limitation: Checkout calculation and international coverage are on paid custom plans
Kintsugi has a well-rated Shopify app and a simple per-action price. A store filing monthly in four states pays about $3,600 a year in filing fees alone.
3. Zamp: best fully managed US service
- Pricing: Quote only; Shopify lists it at about $45–65 per state per month
- Limitation: US and Canada only; no public pricing
Zamp is one of Shopify’s two recommended filing partners. It does everything for you in the US, but at five states that’s roughly $2,700–$3,900 a year with no VAT coverage.
4. Shopify Tax: fine for calculation, not compliance
- Pricing: Free until your store passes $100,000 in sales, then 0.35% per US order (0.25% on Plus), capped at $0.99 an order
- Limitation: Automated filing is closed to new stores and only covers sales up to 31 December 2026
Shopify Tax gets the rate right at checkout, including product-level rules. It doesn’t register you, only sees Shopify orders, and will soon file nothing at all. Shopify itself recommends pairing it with a filing service. See our Shopify sales tax guide.
5. TaxJar: best for a few US states
- Pricing: Starter $39/month, Professional $99/month (200 orders/month tier)
- Filing: 2–4 returns a year included, then $50–55 each
- Limitation: US only
TaxJar is the familiar name in US sales tax. Its included filings run out fast for any store registered in more than one state.
6. Avalara: best for Shopify Plus enterprises
- Pricing: Avalara Select from $799 per state per year, three-state minimum; larger plans by quote
- Limitation: Per-state pricing; VAT is a separate quote
Avalara connects through Shopify’s tax settings and suits brands with a tax team. See GoodVat vs Avalara.
7. Quaderno: best for digital products on Shopify
- Pricing: $29/month (25 transactions), $49 (250), $99 (1,000), $149 (2,500)
- Limitation: No free plan; filing priced by quote; no native Etsy integration
See GoodVat vs Quaderno.

| Kintsugi | 60 filings × $75 = $4,500 | Custom plans only |

Does Shopify file sales tax returns for me?
Not for new stores. Shopify’s automated filing is closed to new stores and only files returns for sales up to 31 December 2026. Shopify points merchants to third-party filing services, so most stores will need a separate tool for registration and filing in 2027.
