Taxes are imported into QuickBooks Online as part of your transactions. QuickBooks Online imports the exact tax amount you recorded during the transaction you did with Square.
QuickBooks Online then uses the tax rates table to match your tax rates from Square to QuickBooks Online.
Sales tax in QuickBooks Online
If you have not set up sales tax in QuickBooks Online yet, you'll need to do that before you import transactions.
From the left menu, select Taxes (or Sales Tax, if you have Payroll enabled) and then set up the tax from the tax centre. If you don't turn on sales tax before you import transactions, tax information from Square will not be imported into QuickBooks Online.
Sales tax/GST in Square
QuickBooks Online uses your tax rates from Square to map your taxes to QuickBooks Online to ensure correct reporting and tax filing. In imported sales receipts, you see the correct tax amounts and tax codes. The tax amounts and codes are also reflected on the Sales tax page in QuickBooks Online.
If you believe you have not set up the tax rates correctly in Square, go back to Square and set up the correct tax types before importing your transactions.
