Numeral Sales Tax for Shopify: Nexus, Registrations and Filing Setup

Numeral Sales Tax is a Shopify app from Numeral, a US company that monitors where a store has sales tax nexus, registers it in new states, and files and remits returns. As of October 2026 the app is free to install and nexus monitoring costs nothing; US filings are $75 each and registrations $150 each. Numeral's own Shopify guide leaves checkout calculation to Shopify's tax settings, so every new registration has to be entered in Shopify before tax is collected in that state. Specialists keep the two in step, connect other sales channels, and sort product tax categories and exempt customers. When no profile below fits, the sales tax setup and bookkeeping specialists linked at the end of this page take on Numeral Sales Tax work as well. This page covers setup work, not tax advice. Confirm what you owe, and where, with a qualified tax adviser.

Where Numeral setups need a second pair of hands

Connecting Shopify from the Numeral dashboard is quick. The settings around it are where stores slip.

Registrations copied into Shopify. When Numeral registers you in a new state, Shopify charges tax there only after the state's sales tax ID is added under Settings, then Taxes and duties. Until someone adds it, sales into that state go out with no tax collected.

Every channel connected. Numeral asks merchants to connect all sales channels, and its listing names Amazon, eBay and Stripe among the integrations. A channel left out is missing from the nexus picture.

Product tax categories. Shopify applies tax rules by product category. An uncategorized catalog makes the checkout figures, and the filings built on them, harder to trust.

Exempt buyers. Wholesale and resale customers need tax collection switched off on their Shopify customer record and a certificate on file. Professional includes exemption certificate management, with the first 50 certificates free.

Past exposure. The free nexus study reviews past transactions. If it shows thresholds crossed in earlier periods, take that to a tax adviser before anything is filed.

Books that agree. Tax collected in Shopify, tax remitted by Numeral and the liability in your accounts should match each period, a monthly job for Shopify bookkeepers.

Numeral's concierge covers simple stores. One store selling only through Shopify into a few states usually needs nothing beyond the concierge service on Professional.

Choosing who sets up Numeral Sales Tax for your store

Two different skills get sold under one name: Shopify tax configuration and tax advice. Know which one you are paying for.

Where does calculation happen? In Numeral's Shopify guide, Shopify's tax settings handle checkout while Numeral registers and files; its tax engine API belongs to the Enterprise plan. A candidate who expects Numeral to change checkout rates by itself hasn't done this setup.

How do you bring a new state live? Listen for a sequence: registration confirmed in Numeral, ID entered in Shopify, a test order shipped to that state, then the first return checked against what was collected.

What won't you do? A setup specialist configures settings and reconciles data. Deciding what you owe for past periods belongs with a qualified tax adviser, and good candidates say so without being asked.

Promises to walk away from. Guaranteed compliance, advice on states you can safely ignore, or no plan for marketplace sales.

Begin with a Numeral nexus check. Pay for a review of the free nexus study against your Shopify tax settings: every state where registration, collection and filing don't line up, on one page.

For deeper Shopify tax configuration, sales tax and VAT setup specialists are the closest match.

Numeral Sales Tax plans, pricing and the Shopify settings it relies on

Three plans, as of October 2026. Monitoring is free: a nexus study once stores are connected, plus physical and economic nexus monitoring and alerts. Professional costs $75 per filing and $150 per registration and adds registrations, filings, remittance, AI product classification, exemption certificates and all US states. Enterprise is custom, with 90+ countries, the tax engine and API, and access to tax lawyers.

Billing terms. Standard accounts run month to month and are billed as filings occur, with no setup fee for standard US filings. Annual terms are offered for fixed rates.

The on-time promise. Numeral states it will pay penalties and interest if a filing isn't on time. Read the terms before treating that as cover for anything else.

On the App Store. Listed since October 2024, English only, working with Amazon, eBay, Stripe, QuickBooks, NetSuite and Microsoft Dynamics 365.

Shopify screens involved. Collection is switched on per state in the United States tax settings with the state's sales tax ID or FEIN. Exempt status sits on the customer record, and ship-from locations decide whether origin or destination rules apply.

The shopexperts guide to Shopify tax setup walks through those screens.

Numeral tax questions from Shopify merchants

How much does Numeral Sales Tax cost?

As of October 2026 the app is free to install and nexus monitoring is free. The Professional plan charges $75 per US filing and $150 per registration, billed as they happen on a month-to-month account. Global VAT and GST coverage is custom-priced on Enterprise. Outside setup help is a separate cost.

Does Numeral calculate tax at Shopify checkout?

Numeral's own Shopify guide has Shopify's tax settings calculate checkout tax, with Numeral handling registrations, filings and remittance. Its tax engine and API are part of the Enterprise plan. After each new registration, add the state's sales tax ID in Shopify so collection starts there.

Is Numeral tax software enough without an accountant?

It automates nexus monitoring, registration and filing, and Professional includes a concierge service. It doesn't decide what you owe for past periods, how an unusual product should be treated, or how filings land in your books. Confirm obligations with a qualified tax adviser and have a bookkeeper reconcile collected and remitted tax.

What should I check after Numeral registers my store in a new state?

That the sales tax ID is in Shopify's tax settings, a test order to that state shows tax, product categories and exempt customers are right, and the first return matches what Shopify collected. If checkout amounts look off, work through why Shopify tax calculates wrong.

Can Numeral cover sales from Amazon and other channels?

Its listing names Amazon, eBay and Stripe among the integrations, and Numeral asks merchants to connect every sales channel. Its nexus monitoring only sees the channels you connect, so link each one before reading the nexus study.

What should I send a Numeral specialist first?

Your Numeral nexus study, the states where you are registered with their IDs, every sales channel you use, screenshots of your Shopify tax settings, your list of exempt customers and the bookkeeping software you use.
