Why Is QuickBooks Payroll Not Calculating Taxes Correctly?

Tax calculation errors usually happen due to outdated tax tables, incorrect company or employee setup, or payroll subscription issues. Let’s explore each cause in detail.

1. Outdated Payroll Tax Table

QuickBooks uses tax tables to calculate current federal, state, and local payroll taxes. If your tax table is outdated, tax amounts won’t calculate correctly or might show zero deductions.

Fix: Always download the latest payroll tax table update before processing payroll. Tax tables change frequently—especially for 2026 compliance.

2. Incorrect Payroll Subscription or Active Service Key

If your QuickBooks payroll subscription has expired or the service key is inactive, payroll calculations stop automatically.

Fix: Revalidate your payroll subscription.

1. Go to Employees > My Payroll Service > Manage Service Key.
2. Verify that your service key is Active.
3. If expired, renew and re-enter the key provided by Intuit.
4. Restart QuickBooks and reprocess your payroll.

3. Payroll Item Setup Errors

Sometimes, payroll items such as Medicare, federal withholding, or state tax are incorrectly linked or missing from your company file. Even a misplaced checkbox can prevent QuickBooks from calculating taxes.

Fix:

1. Open Lists > Payroll Item List.
2. Double-check that tax items like Federal Withholding, Social Security, and Medicare are active.
3. Verify employee pay item assignments under Employees > Employee Center > Payroll Info.

4. Employee Information Missing or Incorrect

QuickBooks calculates taxes based on employee details like filing status, allowances, and work location. Any blank or invalid field can cause QuickBooks to skip tax calculations.

Fix:

1. Go to Employees > Employee Center.
2. Double-click the employee.
3. Check the Payroll Info and Taxes tabs to ensure all details match updated 2026 tax rules.

5. Manual Calculations or Overrides

Manually overriding paycheck details can break automatic calculations. QuickBooks might stop computing taxes until you remove those overrides.

Fix: Edit the paycheck and remove overrides by resetting the tax fields. Then recalculate the payroll using QuickBooks’ automated process.
