## Why Accurate Payroll Tax Calculations Matter

Payroll taxes include federal income tax withholding, Social Security, Medicare (FICA), federal unemployment (FUTA), and applicable state and local taxes. Employers are legally responsible for withholding and remitting these amounts accurately and on time.

Incorrect calculations can lead to:

* Underpayment or overpayment of payroll taxes
* IRS and state tax penalties and interest
* Amended payroll tax forms (Forms 941, 940, state returns)
* Delays in payroll processing
* Reduced employee trust

Maintaining correct payroll tax calculations in QuickBooks helps protect your business from unnecessary financial and legal risk.
