I will fix shopify sales tax errors and checkout tax issues


About this gig
Is your Shopify checkout charging the wrong sales tax or none at all leaving you to cover the gap at filing time?
In 2026, with more states enforcing economic nexus and marketplace rules, one misconfigured setting can quietly drain your margins and flag you with state tax authorities. Most errors trace back to a few common misconfigurations and they're fast to fix once found.
I specialize in diagnosing and repairing Shopify tax setups. Through a secure collaborator invite (no password needed), I'll find exactly why your settings are broken and fix them fast and transparently.
WHAT I FIX:
- Tax charged where you have no nexus
- Missing tax on shipping or digital products
- Over- or under-charging at checkout
- Conflicts with TaxCloud / Avalara / TaxJar
- Tax-exempt & wholesale setup
HOW IT WORKS:
- Send a collaborator invite + describe the issue
- I audit settings and find the root cause
- I fix it and test across states/zips
- You get a clear report of what changed
Note: I'm a Shopify tax specialist, not a CPA confirm filing/nexus questions with your accountant.
Every sale with broken tax settings costs you money. Message me and let's fix your checkout.

FAQ
Do you need access to my Shopify store?
Yes — I'll need collaborator access, which you can grant through Shopify's Settings > Users and Permissions. I never ask for your password or main login.
Can you help if my store is undercharging or overcharging tax?
Yes. I'll review your tax regions, nexus settings, and product tax categories to find the root cause and make sure checkout collects the correct amount.
Do you register sales tax permits or give tax/legal advice?
No — I'm a technical specialist, not a CPA or tax attorney. I fix the Shopify configuration based on the nexus/registration info you provide. For filing or legal questions, please consult your accountant.
What if I use TaxCloud, Avalara, or TaxJar?
That's actually one of the most common sources of these errors — Shopify's native settings often conflict with third-party tax apps. I'll check the integration and sync settings to fix it.
How do you confirm the fix actually worked?
I run live checkout simulations using real addresses across multiple states/zip codes — including states where you do and don't have nexus — to confirm the math is correct before I deliver.
