QuickBooks Online is primarily accounting software. It records business transactions and produces financial reports such as the profit and loss statement and balance sheet.

When QuickBooks Payroll is activated and properly configured, it may calculate payroll taxes and file payroll forms such as Forms 941, 940, W-2, and W-3. It may also file applicable state and local payroll forms. Whether Intuit files these forms automatically depends on the payroll subscription, account setup, and filing settings. Business owners should confirm that each filing was accepted rather than assuming it was completed.

Standard QuickBooks Online does not prepare or file the S corporation income tax return, Form 1120-S, shareholder Schedule K-1 forms, or the owner’s individual Form 1040. QuickBooks information may be exported into separate tax preparation software, but the accounting records must still be reviewed, reconciled, and adjusted before the tax return is prepared.

QuickBooks also does not determine reasonable compensation, calculate shareholder basis, identify every available tax deduction, or provide a complete tax strategy. Software can organize the numbers, but it cannot replace professional review.
