Selling online with Shopify opens up huge opportunities, but it also brings complex tax rules. Whether you’re UK-based and dealing with VAT, selling to US customers with sales tax, or expanding into Europe where GST and VAT both come into play, getting your taxes right is crucial. Get it wrong, and you risk HMRC or IRS penalties, missed tax reclaim, or overpaying none of which help your business grow.
The good news? Staying VAT or sales tax compliant is possible and can be made easy, when you combine Shopify with Xero or QuickBooks. With the right setup, you can automate reporting, stay on top of your liabilities, and sleep easy knowing your books are always ready for tax authorities.
This guide walks you through what every online seller needs to know about tax compliance in the UK, US, and EU, how to automate your reporting, what to check every month, and the best tools for easy compliance. No jargon, no scare tactics—just practical, actionable advice.
UK VAT, US Sales Tax, EU GST What’s the Difference?
Let’s break down the tax basics for Shopify sellers, wherever you do business:
UK VAT (Value Added Tax)
If you’re based in the UK, or sell to UK customers, you almost certainly need to deal with VAT. Standard VAT is 20%, with some products/services charged at 5% or zero. If your business turnover exceeds the VAT threshold (£90,000 as of 2024), you must register for VAT, charge it on eligible sales, reclaim it on expenses, and file regular VAT returns.
Key Points:
- Register once turnover exceeds the threshold
- Charge the correct rate on each product (20%, 5%, 0%)
- Reclaim VAT on eligible business expenses
- Submit VAT returns (usually quarterly) via MTD-compatible software (like Xero or QuickBooks)
- Keep digital records for HMRC
US Sales Tax
Sales tax in the US is even trickier it’s state-based, not federal. This means each state (and sometimes each county/city) can have different tax rates and rules. If your business meets “nexus” requirements (economic or physical presence), you must register, collect, and remit sales tax in that state.
Key Points:
- No federal sales tax rules vary by state
- Nexus rules: economic (sales volume), physical presence, or marketplace facilitator
- Charge the correct tax rate based on customer location
- File returns for each state where you’re registered
- Keep detailed records for each jurisdiction
EU VAT & GST
Selling to customers in the European Union or other countries with GST? You must comply with local rules, including “place of supply” rules (who is responsible for VAT/GST collection) and special regimes like the EU’s One-Stop Shop (OSS).
Key Points:
- VAT registration may be required in each EU country you sell to, unless using OSS
- Digital goods/services have their own VAT rules (Mini One Stop Shop—MOSS)
- VAT rates differ by country
- Keep compliant invoices and records for cross-border sales
Setting Up Automated Tax Reporting
The biggest compliance headaches come from manual errors and missed steps. The smartest Shopify sellers automate as much as possible saving time, reducing risk, and ensuring nothing slips through the cracks.
1. Connect Shopify, Xero or QuickBooks, and Your Tax Settings
Begin by integrating your Shopify store with Xero or QuickBooks. Use a dedicated sync app (like A2X, Link My Books, or Synder) that supports tax mapping. Don’t rely on basic integrations these often miss fees, refunds, or don’t handle VAT/Sales Tax correctly.
What does a good sync app do?
- Pulls every sale, fee, and refund from Shopify, including VAT/tax information
- Posts summary entries to Xero/QuickBooks, matching your bank deposits
- Maps each product, shipping line, and fee to the correct tax code and account
- Supports multi-currency and multi-channel (if you sell on eBay, Amazon, etc.)
2. Set Up Correct Tax Rates and Codes
Within Shopify, ensure every product is assigned the right tax code. For UK VAT, assign 20%, 5%, or 0% based on the item. For US sales, use Shopify’s built-in tax engine to calculate and collect tax at checkout, or integrate a dedicated sales tax app like TaxJar or Avalara for more complex needs.
In Xero or QuickBooks:
- Set up accounts for VAT/Sales Tax collected, VAT/Sales Tax on purchases, and any special regimes (OSS, MOSS, etc.)
- Match Shopify products and tax codes with your accounting software tax rates
- If you’re VAT-registered, enable digital VAT reporting (MTD) for HMRC
3. Automate Invoice Creation and Bank Reconciliation
Your sync app should post each Shopify payout as a single journal or invoice, breaking down sales, tax collected, refunds, and fees. This makes reconciliation easy and ensures all taxes are tracked.
- Xero/QuickBooks matches payouts from Shopify to your bank feed
- Each journal/invoice clearly shows the VAT/Sales Tax portion
- Refunds, discounts, and adjustments are correctly accounted for
What to Check Each Month
Automation saves time, but even the best system needs a regular review to keep you compliant and confident.
1. Reconcile Every Shopify Payout
Every Shopify payout in your bank account should have a matching entry in Xero/QuickBooks, including tax breakdowns. If something doesn’t match, investigate right away—missed fees, refunds, or mapping errors are easier to fix early.
2. Review Tax Codes and Rates
Check that all new products, shipping methods, and discounts are mapped to the right tax codes in both Shopify and your accounting software. New product lines, international expansion, or pricing changes can affect VAT/Sales Tax liabilities.
3. Verify VAT/Sales Tax Collected Matches Returns
Compare the tax collected in Shopify (and shown in Xero/QuickBooks) to what you’re reporting to HMRC, IRS, or local authorities. This catches errors from missed settings or refunds.
4. Check for Nexus (US), Registration Thresholds (UK/EU)
Growing fast? Monitor your turnover and the location of your customers. In the US, you may cross nexus thresholds in new states; in the UK/EU, you may hit VAT/GST registration thresholds or need to use OSS.
5. Monitor Refunds and Chargebacks
Ensure all refunds, returns, and chargebacks are correctly reversing VAT/Sales Tax. This prevents you from overpaying tax on sales that didn’t stick.

Frequently Asked Questions
Can Shopify handle VAT and sales tax automatically?
Shopify collects and displays tax at checkout based on your product settings and the customer’s location. But it’s up to you to ensure rates and codes are correct, and to sync the tax data into Xero/QuickBooks for reporting and returns.
How do I fix a VAT or sales tax mistake from previous months?
If you discover an error, correct your mapping and resync the affected payouts or orders. Adjust your next tax return (HMRC allows VAT adjustments within certain limits) or file an amended sales tax return in the US. Your accountant can guide you through the process.
What if I sell digital products?
Digital goods have special VAT/GST rules—especially for EU customers. Make sure you’re registered for the right regimes (like MOSS/OSS), and use Shopify plus your accounting software to track and report these sales separately.
Do I need to register for VAT in every country I sell to?
Not always! Use EU OSS for pan-European B2C sales, or local registration if you pass country thresholds. For B2B, VAT rules are different (reverse charge may apply). Professional advice is highly recommended as you expand.
How often should I check my Shopify tax settings?
Review settings every month or anytime you launch new products, change your shipping methods, or add new countries to your store.
Can eSeller Accountant help me if I also sell on Amazon, eBay, or Etsy?
Yes! We specialise in multi-channel eCommerce tax compliance, making sure every platform, every payout, and every tax is automated and accurate in Xero or QuickBooks.
