Step-by-Step Guide: Filing Requirements for Payroll Taxes

1. Obtain an Employer Identification Number (EIN)

Before hiring employees or paying wages, register for an EIN with the IRS. This number identifies your business for tax purposes and is required for all payroll filings.

• Where to apply: IRS EIN Online Application
  

2. Classify Your Workers Correctly

Determine whether your workers are employees or independent contractors. Misclassification can result in serious IRS penalties.

• Employees: You withhold and remit payroll taxes.

• Contractors: You issue Form 1099-NEC (no payroll tax withholding).
  

3. Calculate Payroll Taxes

Payroll taxes include both employer and employee portions. Typical deductions include:

• Federal income tax (based on employee W-4)

• Social Security and Medicare taxes (FICA)

• Federal Unemployment Tax (FUTA)

• State income tax and unemployment tax (if applicable)
  

Use payroll software or a CPA to ensure accurate calculations.

4. Deposit Payroll Taxes

Employers must deposit withheld taxes either semiweekly or monthly, depending on total tax liability.

• Use the Electronic Federal Tax Payment System (EFTPS) to make deposits.

• Deposits generally include:

  • Employee income tax withheld

  • Both employer and employee portions of FICA

  • FUTA (quarterly, if owed)
    

Tip: Late deposits incur interest and penalties immediately.

5. File Quarterly and Annual IRS Forms

You’ll file several forms throughout the year:

Form	Purpose	Frequency
Form 941	Reports federal income, Social Security, and Medicare taxes withheld	Quarterly
Form 940	Reports FUTA tax	Annually
Form W-2	Reports employee wages and withholdings	Annually (to employee and SSA)
Form W-3	Transmits W-2s to the SSA	Annually
Form 1099-NEC	Reports payments to independent contractors	Annually
Form 944	For small employers with annual liability under $1,000	Annually (if approved by IRS)

6. File State Payroll Forms

Each state has its own filing requirements for income tax withholding and unemployment insurance. Check your state’s Department of Revenue or Department of Labor website for specific forms and due dates.

7. Provide Year-End Statements

By January 31, you must provide each employee with Form W-2 and each contractor with Form 1099-NEC. File copies with the IRS or Social Security Administration (SSA).

Real-World Example

Example: Let’s say ABC Plumbing LLC runs a team of five employees. Each quarter, the owner files Form 941 to report payroll taxes and deposits funds via EFTPS twice a month (semiweekly schedule). In January, ABC Plumbing issues W-2 forms to employees and files Form 940 for FUTA taxes. By following this routine, the business avoids late penalties and maintains IRS compliance.

Common Mistakes to Avoid

• Missing deposit deadlines – even one day late can trigger penalties.

• Failing to reconcile Forms 941 and W-2 totals – discrepancies can flag IRS audits.

• Incorrect employee classification – treating employees as contractors to avoid taxes is illegal.

• Ignoring state-level filings – states have their own forms and payment schedules.

• Not maintaining payroll records – the IRS requires employers to keep payroll records for at least four years.

Best Practices for Staying Compliant

• Use reliable payroll software to automate calculations and reminders.

• Reconcile payroll reports monthly to catch errors early.

• Calendar IRS due dates for Forms 941, 940, W-2, and 1099-NEC.

• Work with a qualified payroll specialist or CPA to stay current with tax law changes.

• Review IRS updates annually—regulations and filing thresholds can change each year.

  
  

Summary

Filing payroll taxes correctly isn’t just about avoiding penalties—it’s about keeping your business in good standing with federal and state agencies. With the right systems in place, payroll compliance can be simple, accurate, and stress-free.
