Nexus review by state
Your sales compared with all 50 state thresholds, plus the states to register in and watch.
The Problem
Your Sales Crossed State Lines Before Your Tax Settings Did
Nexus arrives quietly. One strong season in a new state can create a duty to collect there, and Shopify only charges tax where you've switched it on.
01 · Unregistered states
Two states show Action required, and nobody has registered.
Your sales by state get compared with each threshold and Shopify's insights.
02 · Wrong exemptions
Clothing shipped to New Jersey gets taxed when it shouldn't.
Products get tax categories, so exempt items get charged correctly.
03 · Filing confusion
Your accountant can't tell which orders TaxJar should count.
TaxJar or Avalara gets connected when you need filing.
04 · Growing liability
Uncollected tax becomes money you owe from your own margin.
Test checkouts to each registered state prove the rates before launch.
Your store started in one state, and tax was simple. Then sales grew. Shopify's liability page now lists two states under Action required, and nobody has registered there. Sweaters shipped to New Jersey get taxed even though that state exempts most clothing, because half your catalog has no product category. Your accountant asks which orders TaxJar should count, and nobody knows. Every month you wait, uncollected tax becomes money you owe from your own margin.
We start with your sales by state, next to Shopify's liability insights, so you know where you have nexus. You register there, and we turn on collection, assign product categories, and set exemptions. When you need filing, we connect TaxJar or Avalara. Test checkouts to every registered state prove the rates before launch, not after a notice arrives.

Our Tax and Nexus Setup Process
From Nexus Review to Live Tax Collection
You see the nexus review, our recommended setup, and a test checkout for every state before any shopper pays tax.
We compare your sales by state with every state's threshold and with Shopify's liability insights. You get the states to register in, the states to watch, and a fixed quote. If Shopify's settings alone cover your states, we'll tell you before we quote.
What's Included
What You Get With Shopify Tax Setup
Every setup covers the nexus review, collection in every state you've registered in, categories, exemptions, test checkouts, and a handover.

What Our Clients Say
What Clients Say After Launch
Feedback from ecommerce teams we have built checkouts, payments, and integrations for.
We were getting plenty of traffic, but far too many people were leaving at checkout. The buying process had simply become too complicated. The team took the time to understand where customers were dropping off, then rebuilt the checkout flow and cleaned up the shopping experience. What I really appreciated was that they didn’t just make the store look better, they actually solved the problems that were costing us sales. The whole store feels faster, simpler, and much easier to buy from now. Exactly what we needed.
We had a different kind of problem. People were visiting the store, adding products to their carts, and then disappearing before they finished the order. We had tried a few apps and made changes here and there, but nothing really seemed to solve the bigger issue. The team went through the shopping experience with us and pointed out things we hadn't really noticed ourselves. They cleaned up the cart and checkout flow, made the mobile experience much smoother, and helped us make the store feel easier to shop. I’m not going to pretend we fixed everything overnight, but it finally feels like the store is helping the sale instead of getting in the way of it.
Our old store was making it way too difficult for people to find products. We had a large catalogue, but the search, filters, and mobile navigation were frustrating customers. The team completely changed how the store handled product discovery and made the experience much easier to use on mobile. I was especially impressed by how much thought went into the customer journey rather than just the visual design. They understood what we were trying to achieve and turned it into a store that actually feels built for our customers. We’re genuinely proud of the result.

Work Culture
Why Merchants Trust Us With Their Tax Settings
A Shopify sales tax mistake repeats on every order until someone notices. These are the habits we bring to every setup.
Nexus checked before settings
We compare your sales by state with each threshold before touching Shopify. You know where you collect and why, instead of switching states on by guesswork.
Categories before overrides
Product categories let Shopify apply exemptions state by state. We set them first and add overrides only on manual collections, where Shopify applies them.
A checkout for every state
We check out to an address in each state you collect in. You see the tax charged beside the expected rate, so errors surface before customers do.
One source per sale
When Shopify and QuickBooks both feed TaxJar, the same sale can count twice. We connect one source per sales channel, so each order is reported once.
Honest about our role
We set up your store, not your tax position. Registration, advice, and filing decisions stay with your accountant, and we work beside them.
Your tax accounts stay yours
Your Shopify, TaxJar, and Avalara logins stay under your business. We work through staff accounts you can remove the day we finish.

Good fit
Stores past a new state's threshold
Your sales into another state just passed its economic nexus threshold, and you need tax collected there before the busy season.
Stores selling exempt products
You sell clothing or other items some states exempt, so each product needs the right category before Shopify applies the exemption.
Multi-channel sellers adding filing
You sell on Shopify, WooCommerce, or BigCommerce, and your accountant wants TaxJar AutoFile or an Avalara integration without double-counted orders.
Wholesale and B2B sellers
Your wholesale buyers send resale certificates, and their orders need to skip tax while retail orders are still taxed.
Agencies with multi-state clients
Your client sells into several states, and you want the state review, settings, and test checkouts done under your brand.
Not a fit
Tax advice or filing
You need tax advice, state registrations, or returns filed for you. That's a job for an accountant or filing firm, and we can work beside them.
VAT, GST, or duties
You sell to other countries and need VAT, GST, or duties at checkout. Our Shopify International Expansion Setup service covers that.
Books don't match Shopify
Your tax collection works, but your books don't match Shopify. Our Shopify QuickBooks Integration service fixes how tax posts to your accounts.
One state, simple products
You sell in one state with simple products, and Shopify Tax already collects there. Its settings are enough, and our $450 setup isn't needed.

Our setup starts at $450. Adding TaxJar or Avalara for filing is $1,050, and multi-channel setups start at $2,200. Shopify Tax is free on your first $100,000 of lifetime sales, then costs 0.35% per US order on most plans, capped at 99 cents.
Our Shopify Tax setup is live within 3 to 5 business days once you've registered in your states. A filing service adds 1 to 2 weeks, mostly for product codes and enrollment. Multi-channel setups take 2 to 4 weeks. Registration runs on each state's timeline, so we plan around it.
Yes, Shopify collects tax at checkout, but only in the states you've added and switched on. It works out the rate from the shipping address, the product category, and local rules. The tax arrives with your payouts, so you hold it until each return is due.
No, not for most stores. Shopify's help center says it doesn't file or remit taxes unless you use Shopify Tax with automated filing, which is closed to new enrollment. It doesn't report to states for you either. One exception: since January 2025, Shopify files tax itself on orders placed in the Shop app. For the rest, you, your accountant, TaxJar AutoFile, or Avalara Returns files each return.
You charge tax in every state where you have nexus and have registered. Nexus comes from a physical presence, such as a warehouse or staff, or from passing a state's economic threshold. Shopify flags a state once your sales reach 80% of its threshold, and your accountant confirms it.
You add each registered state in Settings, under Taxes and duties, enter your permit number, and turn on collection. Shopify Tax then works out rates by address and product category. Assign categories first: Shopify applies exemptions like New Jersey's clothing rule only to products carrying the right category.
Shopify Tax sets rates itself, so you change one with an override. Put the products in a manual collection, then add a product override for that collection and state. Automated collections can't hold overrides, and an override beats the category rule, so we keep them rare.
Yes, you need a permit from each state before you collect tax there. You register with the state's tax agency, not with Shopify, then enter that number when you add the state. Shopify's setup guide lists registration as step one, so we start there too.
A TaxJar Shopify integration starts in the Shopify App Store or on TaxJar's Linked Accounts page, and orders then import daily. On Shopify, TaxJar doesn't calculate tax at checkout. TaxJar's help center says its app reports the tax Shopify collected by jurisdiction, which is what feeds AutoFile.
Yes, TaxJar integrates with QuickBooks Online, but not QuickBooks Desktop, and only fully paid invoices sync. If your Shopify orders already post to QuickBooks as invoices, feeding both into TaxJar can count one sale twice. We connect one source per sales channel instead, so each order is reported once.
