The short answer

Does QuickBooks file your sales tax?

Not on its own. QuickBooks Online automated sales tax works out the rate and tracks what you owe, and you still register, file and pay each state. Zamp calculates in QuickBooks, and our team files and pays every return for one price.

What changes when Zamp runs your QuickBooks sales tax.

Keep invoicing the way you do today. Zamp does the tax work behind each invoice and every return that follows.

Tax recorded in QuickBooks is the tax you file.

Zamp calculates rooftop-accurate tax on invoices, recurring invoices, estimates and sales receipts, and writes it to QuickBooks' own sales tax line. Edit an invoice and the tax and the filing record update together. Your QuickBooks sales tax report and your returns tell the same story.

Does QuickBooks Online file sales tax returns for you?

Not on its own. QuickBooks Online tracks what you owe and when, offers sales tax e-file in some states, and otherwise has you file on the state's website or by mail, then record the payment yourself². With Zamp, our team prepares, files and pays every return on each state's schedule.

What does QuickBooks automated sales tax do?

QuickBooks automated sales tax calculates a rate on each sale from your business address, where you sell or ship, the customer and each product's tax category¹. It also tracks due dates and what you owe. You still need to be registered in a state before you set it up there³.

Does Zamp replace QuickBooks automated sales tax?

Zamp takes over the calculation inside QuickBooks Online. With automated sales tax turned on, Zamp's amount appears in QuickBooks' native sales tax field; without it, Zamp adds its own sales tax line to the invoice. Either way, the amount recorded in QuickBooks is the amount filed.

Do I need to send Zamp a QuickBooks sales tax report?

No. Transactions sync from QuickBooks Online as you create and edit them, and Zamp prepares liability by state each period for you to approve. If you prefer to send data by file, you can export a monthly sales tax report from QuickBooks and upload it to Zamp.

Will Zamp double count Shopify or Amazon sales that post to QuickBooks?

No. You decide, customer by customer, whether Zamp calculates and files, files as charged, or skips QuickBooks transactions that come from another channel. Orders already taxed at checkout are filed as charged, and each sale reaches your returns once.

Which QuickBooks plans does Zamp work with?

Zamp works with QuickBooks Online Simple Start, Essentials, Plus, Advanced and Accountant. QuickBooks Desktop isn't supported today.

How much does Zamp cost for QuickBooks users?

One price based on your monthly order volume and the number of states you file in. Registrations are included, and there's no extra cost for the QuickBooks connection or for syncing your history.

We already use a sales tax provider with QuickBooks Online. How do we switch to Zamp?

Most teams switch at the end of a filing period. We move your existing registrations, filing calendar and QuickBooks Online history over, your current provider files its last period and Zamp files the next, so no return is missed or filed twice. If you're mid-contract, ask about the Zamp buyout.

We haven’t been collecting or filing sales tax everywhere we should. Can Zamp help us catch up?

Yes. A specialist reviews where you sell and where you may already owe. Then we agree a path with you, from filing past-due returns to a voluntary disclosure or registering going forward, and our team does the filing.
