Disclosure: Zamp makes sales tax software and a managed filing service, and Zamp is one of the options below. Facts about other vendors come from their own public pages, checked on 5 November 2026, and we say where another option fits better. How we compared
Short answer
- Software files, and your team handles registrations and notices. Up to 200 orders a month, Numeral or Kintsugi ($75 a return) cost least under about 15 returns a year; TaxJar Starter costs least above that. From about 2,500 orders, Avalara is often lower (see the order-volume table).Sources: Numeral+2NumeralNumeral pricingnumeral.com/pricingChecked KintsugiKintsugi pricingtrykintsugi.com/pricingChecked TaxJarTaxJar pricingtaxjar.com/pricingFirst checked · Last checked

List prices in USD, checked 5 November 2026. TaxJar: monthly billing at the 200-orders tier, plus pay-as-you-go AutoFile after the included credits; registration $299 per state. Avalara: annual per-state price; registration $403 per location. Numeral: $75 per return, $150 per registration. Kintsugi: $75 per return or registration. "First year" assumes the vendor registers you in every state you file in; state registration fees, where a state charges one, are extra for everyone.Sources: TaxJar+2TaxJarTaxJar pricingtaxjar.com/pricingFirst checked · Last checked AvalaraAvalara pricing informationavalara.com/us/en/products/pricing.htmlFirst checked · Last checked NumeralNumeral pricingnumeral.com/pricingChecked
- At 10 states filing monthly, AutoFile fees are $5,900 of TaxJar Starter's $6,368 a year, about 93% of the bill (84% on Professional).
- After the first year, a $75-per-return tool beats TaxJar Starter's list price only up to 14 returns a year, and Professional's up to 48. Above that, TaxJar's list price is lower. If you're leaving TaxJar, you're probably already registered, so the per-year rows are the ones to compare.
- Registration fees widen the gap in year one. At 3 states, Kintsugi's first year is $1,125 and TaxJar Starter's is $1,865, because TaxJar charges $299 per state to register you and Kintsugi $75.Sources: TaxJar+1TaxJarState sales tax registrationstaxjar.com/product/registrationsChecked KintsugiKintsugi pricingtrykintsugi.com/pricingChecked
- At up to 200 orders a month, Avalara costs more than TaxJar in every row. At 10 monthly states it is $1,622 a year more than Starter and $422 more than Professional, the TaxJar plan that includes notice management. Avalara's $403-per-location registration makes its first year at 10 states $12,020, against $9,358 for TaxJar Starter. Avalara's case is that its price doesn't change with order volume or return count.Sources: Avalara+1AvalaraAvalara pricing informationavalara.com/us/en/products/pricing.htmlFirst checked · Last checked AvalaraAvalara sales and use tax pricingavalara.com/us/en/products/sales-and-use-tax/priChecked

- TaxJar Starter costs less than Avalara up to its 1,000-order tier in all three of our scenarios (3, 5 and 10 states).
- At 2,500 orders, Avalara is cheaper than Starter in two of the three (3 states quarterly and 10 states monthly), but not at 5 states quarterly ($3,995 vs $3,528).
- If you need Professional's features (real-time API calculation, notice management, nexus alerts), Avalara costs less from the 1,000-order tier in all three scenarios.
- The $75-per-return break-even moves up with order volume. Numeral or Kintsugi cost less than Starter up to 24 returns a year at TaxJar's 500-order tier, and up to 43 at 1,000.
Also not in the table: TaxValet's published range is $12,000–$48,000 a year. Stripe Tax Complete's 12-return tier is $430 a month ($5,160 a year).

If price is your only reason to leave, run the math with your own return count. For many sellers, the bigger differences are who registers you, who answers state notices, and who you can call.

"Their quick monthly emails for review simplify our operations, allowing me to spot-check a few states before approving their plans for filing and remittance.

When Zamp isn't the right choice
- Up to 200 orders a month, and you're fine handling registrations and notices: Numeral or Kintsugi below about 15 returns a year; TaxJar Starter above that.

Selling on WooCommerce, Etsy or other marketplaces
On marketplaces, the marketplace usually handles the tax. Etsy's help center says it calculates, collects and remits US sales tax on orders shipped to US buyers, and sellers can't opt out.Source: EtsyEtsyUS state sales tax on Etsy ordershelp.etsy.com/hc/en-us/articles/360000343968-HowChecked Sales on your own WooCommerce or Shopify store are yours to collect and file. Two things to check with any vendor:
- Marketplace orders are reported as marketplace sales, so the tax isn't filed twice.
- How it counts marketplace sales toward nexus. States differ on whether those sales count toward your economic nexus threshold.
- On TaxJar, WooCommerce stores need Professional for real-time checkout calculation. TaxJar's own plan guide says the API is "essential for Woo, BigCommerce, Magento, or custom-built stores", and that Starter suits marketplace sellers.Source: TaxJarTaxJarHow much does TaxJar cost?support.taxjar.com/article/139-how-much-does-taxChecked

If you sell on Shopify: what changes at the end of 2026
Shopify Tax calculates and collects at checkout. Shopify's help center says it doesn't remit for you unless your sales tax is managed by Shopify or you're enrolled in automated filing.Source: ShopifyShopifyFiling and remitting US sales taxhelp.shopify.com/en/manual/taxes/us/filing-remitChecked
Automated filing is ending. It covers sales through 31 December 2026, and you can download filing records until 30 April 2027. Shopify's filing-partner page lists two services for stores moving off it: Numeral, at $50 per return for a year, and Zamp, with three free months if you sign up by 31 January 2027. TaxCloud advertises its own switch offer.Sources: Shopify+1ShopifyAutomated filing partnershelp.shopify.com/en/manual/taxes/shopify-tax/autChecked TaxCloudTaxCloud pricingtaxcloud.com/taxcloud-pricingChecked
Shopify Tax costs 0.35% of each taxed US order on Basic, Grow and Advanced, and 0.25% on Plus, after a $100,000 sales threshold. The fee is capped at $0.99 per order. Include it if you're comparing TaxJar with "Shopify Tax plus a filing partner."Source: ShopifyShopifyShopify Tax pricinghelp.shopify.com/en/manual/taxes/shopify-tax/priChecked
How to switch from TaxJar without missing a filing
- Cut over at the end of a filing period. TaxJar files the last period and the new provider files the next.
- Turn off AutoFile for the periods the new provider will file, so nothing is filed twice.
- Don't buy AutoFile bundles you won't use. They're non-refundable.Source: TaxJarTaxJarHow much does AutoFile cost?support.taxjar.com/article/409-how-much-does-autChecked
- Export your reports and history before you close the account. TaxJar lists report exporting on Professional, so check what your plan allows.Source: TaxJarTaxJarTaxJar pricingtaxjar.com/pricingFirst checked · Last checked
- List registrations, filing frequencies and portal logins. The state accounts are yours.
- Move exemption certificates for exempt and wholesale customers.
- Check your contract. On an annual plan, ask any new provider whether it credits your remaining term. Zamp's buyout program does.Source: ZampZampZamp buyout programzamp.com/buyoutChecked

What is the best TaxJar alternative?
It depends on who does the work and your order volume. Under 200 orders a month: Numeral or Kintsugi below about 15 returns a year, TaxJar Starter above that. Up to 1,000 orders, Starter costs less than Avalara in our scenarios; from about 2,500, Avalara often costs less. Stripe billing: Stripe Tax. SST states: TaxCloud. A team for registrations, filing and notices: Zamp (our product) or TaxValet.
Is there a free alternative to TaxJar?
Not for filing. Kintsugi's Free plan monitors exposure but doesn't file. Zamp's Free plan is a one-time nexus review. In SST states, TaxCloud and Avalara's SST plan can use state-funded filing for eligible sellers. TaxJar offers a 30-day free trial.Sources: Kintsugi+2KintsugiKintsugi pricingtrykintsugi.com/pricingChecked ZampZamp pricingzamp.com/pricingChecked TaxJarTaxJar pricingtaxjar.com/pricingFirst checked · Last checked
Which TaxJar alternatives file sales tax returns for you?
All seven offer filing (Stripe Tax on its Complete plan). The difference is what surrounds the return. With Avalara, Kintsugi, Numeral, Stripe Tax and TaxCloud, your team manages setup and anything outside the plan. With Zamp and TaxValet, a team also handles registrations and state notices.
Who owns TaxJar? Is it part of Stripe?
Stripe owns TaxJar. Stripe announced the acquisition on 27 April 2021. TaxJar still sells its own plans and says current customers are not being moved to Stripe Tax, Stripe's separate tax product.Sources: Stripe+1StripeStripe will acquire TaxJarstripe.com/newsroom/news/taxjarChecked TaxJarPricing changes FAQsupport.taxjar.com/article/1227-frequently-askedChecked

How much does Zamp cost?
Zamp doesn't publish a price; it quotes after a sales call. See Zamp's entry above for what its pages say the price includes. Shopify's help center lists a three-free-months offer for merchants leaving automated filing who sign up by 31 January 2027.Sources: Zamp+1ZampZamp pricingzamp.com/pricingChecked ShopifyAutomated filing partnershelp.shopify.com/en/manual/taxes/shopify-tax/autChecked
How we compared
Every price and feature comes from the vendor's own pages, checked 5 November 2026 and listed below, as US-dollar list prices. Where a vendor doesn't publish a number, we say so. G2 ratings and review counts are as shown on G2 on 5 November 2026. Quotes are verbatim, linked and labelled, and patterns are counted from full review text. Zamp pays for G2's API plan. Zamp facts come from zamp.com and are attributed to Zamp, backed by Shopify's help center, Zamp's trust center or a named customer where possible. Zamp's price is a quote, so it isn't in our cost math. We recheck monthly.
