Let's break down the essential steps you need to take for a successful first payroll run.

Gather Employee Information

Before you can run payroll, you need to collect necessary information from your employees. This includes: 1. Personal details — Full name, address, and Social Security number are essential for tax reporting. 2. Tax forms — Employees should fill out Form W-4 to determine their federal income tax withholding. 3. Employment eligibility — Ensure you have completed Form I-9 for each employee to verify their eligibility to work in the U.S.

Having accurate and complete employee information prevents issues down the line. Make sure to keep these documents secure and easily accessible.

Understand Payroll Taxes and Rates

Understanding the payroll taxes you need to withhold is crucial. For 2026, here are the key tax rates: 1. Social Security — The rate is 6.2% on wages up to $176,100, as set by the IRS. 2. Medicare — This tax is 1.45% on all wages. 3. Washington State Paid Family and Medical Leave (PFML) — The total rate is 1.13%, with the employee share being 0.8072%, according to the Washington ESD's November 2025 announcement. 4. Washington Cares Fund — A tax of 0.58% applies to all wages. 5. Washington Labor & Industries (L&I) — The rate varies based on the risk class code of your business.

Make sure to stay updated on these rates, as they can change annually. Proper understanding ensures that you withhold the correct amounts, preventing any penalties.

Choose a Payroll System

Selecting the right payroll system is vital for managing your small business payroll. You have several options: 1. Manual processing — This method involves calculating payroll by hand, which can be time-consuming and error-prone. 2. Software solutions — Many payroll software options automate calculations and filings, making them a popular choice for small businesses. 3. Outsourcing — Hiring a payroll service can take the burden off your shoulders, allowing you to focus on other aspects of your business.

Each option has its pros and cons. Consider your budget, the complexity of your payroll needs, and how much time you can dedicate to payroll processing.
