Published September 29, 2026·6 min read

As a small business owner or solo-entrepreneur, adding employees to payroll can feel overwhelming. You're not just managing your own finances anymore; you're also responsible for your employees' paychecks, taxes, and compliance with various regulations. Understanding the payroll setup process is crucial to ensure you remain compliant with federal and state laws. This guide will walk you through the essential steps to add employees to payroll, making the process straightforward and manageable.

Understanding Payroll Setup

Before you can start adding employees to payroll, it's vital to understand what payroll setup entails. Payroll setup includes gathering employee information, determining pay rates, and understanding tax obligations. You'll need to collect personal details from your employees, such as their Social Security number, address, and tax withholding preferences. It's also essential to decide on a pay schedule—weekly, bi-weekly, or monthly. Knowing the specifics of how you'll process payroll will streamline the entire operation.

Gather Necessary Employee Information

The first step in adding employees to payroll is gathering all required information. Here's what you'll need: 1. Personal Information — Collect the employee's name, address, Social Security number, and contact details. 2. Tax Forms — Have the employee complete a W-4 form to indicate their withholding preferences. 3. Pay Rate — Determine how much you'll pay the employee and how often. 4. Employment Status — Clarify whether the employee is full-time, part-time, or temporary. This information is crucial for accurate payroll calculations.

Calculate Payroll Taxes

Once you have all employee information, the next step is to calculate payroll taxes. As of 2026, these are the key rates you need to consider: Social Security tax is 6.2% on wages up to $176,100 (the IRS set this wage base for 2026). Medicare tax is 1.45% on all wages. In Washington, the Paid Family and Medical Leave (PFML) tax is 1.13% total, with the employee share being 0.8072% (per the Washington ESD's November 2025 announcement). Additionally, the WA Cares Fund tax is 0.58%. Depending on your industry, the WA Labor & Industries (L&I) tax will vary by risk class code. Understanding these rates will help you accurately calculate how much to withhold from your employees' paychecks.
