Setting up sales tax in QuickBooks Online

Invoices are not adding sales tax, the rate looks wrong, or the Sales tax center shows agencies you do not file with — or is missing one you do.

In the current 2026 US menu, go to All apps, then Sales Tax, then Sales Tax Settings (to turn it on) and Overview (to set up automated sales tax and agencies). Some companies still see a Taxes item in the left-hand menu. Labels vary a bit between plans.

Likely causes

• Sales tax was never turned on, or the business address used for tax was incomplete.
• The company is registered in another state or local agency that was never added to QuickBooks.
• Customers or products are marked taxable or non-taxable in a way that does not match how you actually sell.
• The filing frequency in QuickBooks does not match the frequency the agency assigned to you.

Quick fixes

1. Open Sales Tax Settings and confirm that you charge sales tax. Save.
2. Go to Sales Tax Overview and choose to use automated sales tax if it is offered. Confirm the business address QuickBooks will use for tax.
3. Add every state or local agency where you are actually registered to collect. For each one, set the filing frequency (monthly, quarterly, annual) to match the agency's notice. If you are not sure whether you must register somewhere, confirm that with the agency or your tax advisor before you add it.
4. Review a sample invoice. Check that taxable products and services are marked taxable, that tax-exempt customers carry their exemption, and that the calculated tax looks right for the ship-to or service location.
5. Before each filing, run the sales tax liability report in the Sales Tax center and compare it with the agency return. Record the payment in QuickBooks so the liability clears.

A few more questions

Does QuickBooks decide where I owe sales tax?

No. Automated sales tax helps calculate rates for the agencies you add, but you are responsible for registering where you have to and adding only those agencies.

Why is tax not appearing on an invoice?

Common reasons are that sales tax is not turned on, the product is marked non-taxable, the customer is exempt, or the address on the invoice is incomplete.
