In QuickBooks Online, which steps correctly enable Sales Tax and configure rates to products and services?

• A. Go to Taxes > Sales Tax, enable the feature, create or select tax agencies, define tax rates, and assign tax codes to each product or service item.
• B. Go to Settings > Taxes, enable Sales Tax automatically, and apply a single tax rate to all products.
• C. Open Invoices, choose Tax, and set a default tax rate for the entire invoice.
• D. Enable tax reporting and set tax codes on the Customer profile only.

Answer: (A)

Setting up Sales Tax in QuickBooks Online requires turning the feature on, then defining the jurisdictions (tax agencies), creating the tax rates for those jurisdictions, and tagging each product or service item with the appropriate tax code so the correct rate applies on transactions. This end-to-end setup is necessary because the system needs to know where the tax is due (the agency), what rate to charge (the rate), and which items are taxable (the codes). Without enabling Sales Tax, the feature won’t calculate at all; without tax agencies, there’s nothing to report against; without defined rates, there’s no percentage to apply; and without assigning tax codes to items, QuickBooks wouldn’t know which items should incur tax and which rate to use.

In contrast, trying to enable taxes and apply a single rate to all products ignores regional variations and different tax treatment for items, which QuickBooks supports through multiple rates and codes. Simply opening an invoice and setting a default rate bypasses the necessary setup of agencies and item-level tagging. And focusing tax codes only on the Customer profile leaves item-level application unresolved, since tax calculations are determined by the item and its assigned code, not just the customer.
